Description
[0001] This case is a divisional of U.S. patent application Ser.
No. 09/797,325, filed Mar. 1, 2001, which claims the benefit of
priority of U.S. provisional patent application Ser. No.
60/186,123, filed on Mar. 1, 2000.
BACKGROUND OF THE INVENTION
[0002] The present invention generally relates to the field of
extracorporeal blood processing systems and, more particularly, to
providing information management and/or data manipulation and/or
optimization capabilities to, in and/or with such systems.
[0003] The utilization of blood taken from donors and transfused
into recipients is well known for purposes of treating medical
conditions. More recently, selected blood components have been
separated and collected from donated blood for subsequent
transfusion into recipients for the more specific therapeutic
benefits of those particular blood components. The primary blood
components of current interest in many separation and collection
technologies include platelets, red blood cells, white blood cells,
stem cells and plasma.
[0004] In the harvesting of blood components, blood is removed from
a donor through a needle assembly or other blood access device and
may thereafter be processed by centrifugation or other appropriate
separation techniques to isolate and collect the desired
components. This procedure is often carried out very effectively in
an on-line procedure wherein blood is removed from a donor,
processed in and through a disposable extracorporeal fluid circuit
to obtain the desired components, and the uncollected components
thereafter returned to the donor. Two illustrative blood component
collection systems that provide for this type of on-line blood
component collection procedure are the COBE Spectra (Registered
Trademark) and Trima (Registered Trademark) apheresis systems,
which are commercially available from the assignee of the present
application.
[0005] The yield of a particular collection of blood components
from such a process is an important factor in the ultimate
usefulness of those particular components. For instance, in the
United States a minimum yield is associated with a collected blood
component product in order for that product to meet certain
criteria and qualify for use as a transfusable blood component
product. The COBE Spectra and Trima apheresis systems presently
accommodate for this requirement by processing certain donor
biological data such as height, weight, gender, and platelet
pre-count or hematocrit, together with pre-configured and/or
operator-input data such as the total procedure time, and
system-related data such as the type of collection procedure (e.g.,
single or double needle) and collection efficiency to generate
certain process parameters such as the inlet flow to the apheresis
centrifugation device (including, for example, the combined flow of
whole blood from the donor plus typically a flow of anticoagulant).
These apheresis machines then generate a predicted blood component
yield from these data as well.
[0006] An additional consideration presently in the United States,
for example, relating to blood component yield is that the yield is
determinative of the product classification. With regard to
platelets, a single platelet product is presently considered to be
a collection of 3.times.1 011 platelets and a double platelet
product is considered to be a collection of 6.times.1 011
platelets. If a collection is between 3.times.1 011 and 6.times.1
011 platelets, it is still considered to be a single platelet
product. This classification as a single or double platelet product
is important to blood component collection facilities (e.g., blood
banks/centers) since a double platelet product may have a higher
selling price than a single platelet product and may also have a
greater benefit for the recipient/patient. The yield of a
particular collection of blood components may also be a relevant
consideration for certain therapeutic treatments (e.g., red blood
cell or plasma exchanges).
[0007] Furthermore, advances in blood component collection
technologies offer the possibility of collecting multiple
combinations of products from a single donor. These products can be
defined within a large range of volumes and contents. Add to this
multitude of collection choices, a multitude of donors with
differing physiologies, each being subject to potential variations
in collection procedures to yield a potential very large plurality
of choices of products to be collected, as may be desired.
[0008] Still other important considerations relating to blood
component collection systems relate to the donor and product
demand. For instance, blood component collection facilities are not
only experiencing an increase in the overall demand for blood
components, but the demand now typically varies between the blood
component types as well. Moreover, the supply of donors is
unfortunately inadequate in many cases, and donor time constraints
are becoming more prevalent. Furthermore, obtainable yields from a
given donor may vary from one blood component to another, i.e., one
donor may be a better platelet source than a red blood cell
source.
[0009] The result is a large number of variables which must
preferably be simultaneously managed in order to meet the blood
bank collection goals which will thus also satisfy the needs of the
ultimate hospital or like customer. Computerized information
systems are tools, which are beginning to prove useful in assisting
in controlling parts of blood collection processes. This will
likely further impact, if not transform, how blood banking will be
managed in the future. Computer information systems may prove
important in aiding the provision of just-in-time supply of
products to meet customized demand for blood products and better
satisfying the individual needs of patients and providers.
Automated component collection systems will also allow for
flexibility in producing customized blood products in a
just-in-time fashion from potentially fewer donors to help meet the
demands of patients and providers.
[0010] In view of the foregoing, it should be readily understood
that better management of the various aspects of blood component
collection processes and systems is increasingly desirable in
providing preferred product collection and customer supply
options.
SUMMARY OF THE INVENTION
[0011] The present invention relates in one application to a blood
component collection system and the provision of management
capabilities, which may include the incorporation of data
manipulation and/or optimization principles. Generally, the present
invention preferably utilizes an information management system,
which provides simplified donor data storage and control as well as
communications with actual blood component collection machines to
both ease and optimize the set-up and operation thereof. The
principles of data manipulation and/or optimization are further
improved also, particularly in terms of the individual donor, a
given pool of donors, the particular blood component collection
system, and/or the blood component product or products to be
collected. For instance, the present invention may be adapted to
provide for the collection of a predetermined quantity of at least
one predetermined blood component, or more typically the collection
of such blood components within a particular range in a "minimum"
amount of time, and/or for the collection of a "maximum" quantity
of at least one predetermined blood component in a fixed amount of
time, all based upon certain donor and/or blood center defined
process conditions. Moreover, the present invention may be adapted
to provide for blood component inventory control by basing donor
selection and/or collection procedure selection (in terms of the
type of blood component to be collected) on blood component demand
and/or existing inventory. In addition, the present invention may
be adapted to provide for further donor management by collecting
that blood component type or types from the donor, which provides a
maximum yield.
[0012] A preferred central computational, data storage,
manipulation and communication system serving as the primary basis
of the present invention is preferably a software-type of
application run in tandem with one or more hardware devices
including, for example, a data input device, a data storage device,
a data manipulation device and one or more communications devices
which connect in data communication relationship one or more of
such input, storage and/or manipulation devices to at least one
blood component separation and/or collection machine. The software
application may be and in preferred form is operable in/on a
Microsoft (Registered Trademark) Windows (Registered Trademark)
software platform (or a similar such system) that allows blood
donation center operators to prepare apheresis machines and donors
for apheresis donations in an automated manner. The present system
may preferably have two primary components, a
computation-manipulation application with associated software and
devices, and a server system also including associated software and
devices. The computation-manipulation application is used by the
blood center staff to perform data management and/or manipulation
functions. The server system is used preferably to store data and
to provide communications with the apheresis machines and/or other
information systems. In a typical setting, one or more operators
from different locations within a single blood center and/or
remotely from various disparate blood centers (and/or other sites)
can communicate with a centralized server system to perform
specific functions such as donor check-in, preparing a donor for a
particular donation, or finalizing and/or preparing reports on
collection activities, inter alia.
[0013] An important purpose of the present system is to address
various challenges in the area of blood donation management
including increasing productivity, better donor
qualification/utilization and improved product quality control and
disposition.
[0014] Increased productivity may be accomplished through
centralized management of apheresis machine configurations.
Operators and/or system administrators may easily create and store
several configurations using the present system on a centralized
server/computer or a like environment. These configurations are
preferably kept in a centralized database and can be downloaded to
each apheresis machine on a permanent or a temporary/one-time
donation basis. This reduces the inherent contemporary difficulty
of editing apheresis machine configurations by allowing the
operator to update a centralized configuration and not be required
to repeatedly make the same change on several stand-alone apheresis
machines.
[0015] Donor qualification/utilization may be improved through
procedure customization and/or optimization. Each donation may be
customized by this system to account for the current needs of a
blood center and/or optimized by what each particular donor is
eligible/qualified for or capable of donating. This allows the
operator to determine what product or combination of products will
best be collected even before the donor is connected to the
machine. It also allows the blood center operators to see what
tubing set is required for the donation. With this information the
customer can avoid wasting tubing sets and reduce incomplete
procedures. Decision support for donor eligibility is a preferred
beneficial feature of the system. At a minimum, eligibility may be
determined by the interval between donations, the number of
donations previously given, the blood component loss over a period
of time, and other donor screening issues.
[0016] Another important, yet optional feature of donor
qualification/utilization and management in using a system of the
present invention involves donor recruitment. The present invention
provides a tool that may analyze and predict donation outcomes
prior to running a donor on an apheresis machine. Such a tool can
use donor and procedure information from the central database or
optionally from an imported text file containing the required
minimum information. Thus, such predictions can be used
independently of actual runs on donors, even those actual runs
involving the system of the present invention. These predictions
may also be independent of procedures not currently entered into
the central database, but rather from data generated by the blood
center or data obtained from the blood center information system.
Donor data may refer to a particular donor or to a statistical
distribution of donor population. At a minimum, the system of the
present invention may preferably analyze the outcomes of the
following three scenarios: a) a single donor relative to many
possible procedures; b) many donors relative to a single type of
procedure; and c) many donors relative to many possible
procedures.
[0017] Improved product disposition may be enhanced through the
provision of alterable prioritizations of the product needs of a
blood center. The present system presents the capability of
providing a prioritization of which products are preferred to be
collected. This allows the blood center to begin to incorporate the
concept of demand drive where donors are used to fill existing
and/or imminent product needs. This also reduces waste from the
over collection of certain products. The system also presents the
capability to tailor a blood center's priorities by blood type, CMV
status, and/or HLA type matching.
[0018] The present system also provides for quality control (QC) in
the entry of laboratory data for products collected by blood
separation devices operated in accordance with the present
invention. Data may include (but is not limited to) measured
yields, volumes, concentrations, product contaminants, and pH
levels. The present system provides the capability to associate
anomalous QC lab data to donation events and to generate exception
reports where the device prediction and QC lab results may differ.
The present system can also utilize this data to automatically
calculate and adjust a separation device's yield calibration value,
i.e., a yield scaling factor, depending on the particular device
type.
[0019] Overall procedure and apheresis machine management may also
be improved by recording procedure history information for each
apheresis donation and storing it in a central database. Thus, the
system may contain a detailed log of each donation. These logs can
include procedure comments, tubing sets used, alarms experienced,
adjustments made, and machine run summary information. Operators
may additionally annotate this procedure history information and/or
obtain reports using such logged information.
[0020] To implement the above and other features of the present
invention, it is preferred that a central computational/data
storage system be established according to the present invention so
that it communicates with each of one or more blood collection
machines, preferably apheresis machines, in both directions (even
though one-way communications may be desirable in certain
situations). Two way communications provide for directing to each
machine configuration information of both temporary and permanent
natures, procedural lists and priority information, donor vital
information, including height, weight, gender, blood component
pre-counts and total blood volume (TBV), as well as donor
identification which may include a donor picture with the donor's
name and perhaps the date of birth. The centralized system may then
also communicate in the reverse direction with each machine to
retrieve from each apheresis machine immediate information
regarding conditions such as alarms, procedure adjustments, and run
progress (product collection information) for monitoring purposes.
It also provides for retrieving end of run summary information and
run logs after each procedure is complete. The centralized system
can also use data from the apheresis devices to detect and isolate
potential maintenance problems before they manifest themselves to
the blood center. These can then be reported so that preventive
maintenance may be performed.
[0021] The present system preferably uses prediction algorithms
like those used in the COBE Spectra and/or Trima apheresis
machines. Moreover, the prediction algorithms can also be applied
to individual donors, a reference donor list, and/or ranges of
donors within the database. This capability is helpful to
predetermine donor eligibility for specific product collections,
and what products would be available given specific apheresis
machine configuration settings.
[0022] The present system has been developed with an open
architecture to provide integration capabilities and collaborative
capabilities with other computing environments (such as Mak and/or
Wyndgate donor database information systems) and/or with other
component separation machines (such as the Haemonetics and/or the
Baxter series, e.g., the MCS+ (Trademark) and/or the Amicus
(Trademark) and/or CS-3000 (Trademark) apheresis machines, inter
alia). This ultimately will allow ancillary applications to be
used. For example, this allows for the manipulation and formatting
of donor identification data and/or images obtained from other
information or software systems. Bar code capability is another
preferable alternative, which may be incorporated into the present
system. Any field entry point which could/would require keyboard
data entry could be filled using a bar code reader. In addition,
special entry fields such as unit or batch number, manufacturer and
expiry dates of disposable tubing sets may be fully decoded
utilizing administratively editable decoding information; an
example is manufacturer identification of a disposable tubing
set.
[0023] Products can also be customizable from a collection
standpoint. This is a potential first step toward a "dosing" model
whereby components may be collected in quantities matching specific
medically or doctor prescribed doses. These customizable products,
although perhaps not directly donor specific, could also be set up
in a way to take care of situations such as a "first time" donor or
persons known as "lumpers," i.e., those persons whose component
products show a certain tendency to clump or aggregate.
[0024] After determining which product or products are to be
collected, each donor can be assigned to a specific apheresis
machine. Monitoring real-time machine status from a central system
is useful to determine to which machine each donor should be
sent.
[0025] The present system has been designed to satisfy an optional
yet desirable three room operational flow scenario. The basic three
room scenario involves processing donors sequentially through three
steps which may correspond to three different rooms; namely, donor
registration or reception, donor interview/screening and donor
utilization rooms. This model has been suggested for providing
smooth operation of the blood component collection process.
[0026] During or after the run, numerous standard reports may be
made available to provide the donation center information related
to specific runs, sequences of runs, exceptions, etc. Although the
reports are preferably standardized, customization may also
preferably be made possible through the simple use of report
wizards. The present system preferably also utilizes an industry
standard report engine.
[0027] The central database provides the system with the capability
of storing and maintaining data relevant to the entire blood
component collection process such as, donor demographic
information, machine configuration information, run information and
lab result information. Lab data can also be entered into the run
record to complete the product collection run record. This data can
be used to provide feedback to the process. The communication
software and hardware enable the pulling of data from and
transmission of data to a common or central data repository.
[0028] This system may be used in a stand-alone configuration or in
collaboration with a blood banking information system, especially
for transfer of donor demographics and like donor identification
information. The blood center information system is preferably
considered the master when linked. Fire wall protection may be
provided through password protection schemes, message formatting
requirements and/or hardware communications interfaces. This
provides the assurance that the integrity of the apheresis machine
is maintained during connectivity of this system with such
machines(s) and/or with other systems. The present system can also
utilize a "standard" customer network for communications between a
central system server and operators. This concept of collaborative
networking particularly with pre-existing networks can minimize the
"re-wiring" that otherwise might have been necessary.
[0029] Connectivity may also be utilized to provide collection data
to the blood bank information system after the run is complete.
This two-way communication strategy allows the present system to
optimize the procedure and device selection based on the blood
center's current priorities, rather than making these selections
less-optimally at donor registration time. The as-run collection
data may also synchronize the blood bank information system to the
actual products, yields, and volumes donated.
[0030] Further, this system preferably utilizes formal and de-facto
standards such as SQL interfaces to the database, ethernet
protocols for communications, and preferably Oracle (Trademark)
reports for report generation.
[0031] In the present system, an apheresis machine, which is
preferably also operable in an off-line mode, may upload run
information to a central server system when the apheresis machine
is connected on-line with the central server system. This feature
could also be used for mobile or satellite operations.
[0032] An additional preferred functionality is connectivity with a
blood center information system. Donor data will preferably be
down-loadable to the central server system of the present invention
from the blood center information system. This will allow real time
updating of donor data in the central database of the present
invention from the database of the blood center information system.
Other alternatives of the present system may also include
connectivity of the central data manipulation and/or storage system
to apheresis machines from a plurality of manufacturers.
[0033] Of the various methods of data transfer available, an option
is a web server set-up. With specially developed applets, this
allows the local user or a remote user (with permission) to browse
the operator's database for pertinent information. Thus, this
system can also be accessed remotely and provides an external
"gateway" to run-logs from each apheresis machine. Security can be
established to obscure sensitive data. An administration/security
optional feature would allow the system to be configured with the
concept of user types for security. A system administrator would
have the most privileges and a guest would have the least number of
privileges.
[0034] The present system provides an opportunity to circumvent
shortcomings in the operational procedures forced on a blood center
by the use of pre-existing blood bank software. Specifically, the
present system may overcome the problem of a blood bank software
system pre-selecting blood components to be collected rather than
having the present system perform this selection process. The way
this is achieved is unique in that data is exchanged with the blood
bank software system during the process flow of information. This
is different from having either system depend on inputs from the
other system and then wait for outputs.
[0035] The present invention also preferably may be characterized
as a blood component collection system having blood component
product-based or time-based optimization capabilities. One
embodiment comprises a method for collecting at least one
predetermined blood component (e.g., a collection of platelets or
red blood cells or plasma) from a source of whole blood using a
blood component collection system, which includes a blood component
collection device running according to a particular collection
procedure. More particularly, a desired yield of the predetermined
blood component(s) may be identified (such yield including a single
yield or range of yields) and biological data relating to the
source of whole blood is provided to the blood component collection
system. This data may also include statistically developed
modifications based upon categories of data for multiple sources of
whole blood as contained within the central server systems. Also, a
value or magnitude may be associated with each of the various
process parameters used in the collection procedure. A magnitude of
at least one of these process parameters is preferably derived from
the biological data and the desired yield and optionally also the
statistically derived data from a plurality of whole blood sources.
These magnitudes, including all magnitudes of process parameters
derived from the desired yield, are input to the blood component
collection system. Thereafter, the collection procedure is
performed with the blood component collection device and with the
input process parameters to collect the desired yield of at least
one predetermined blood component(s) from the whole blood
source.
[0036] In a time-based optimization method, a total procedure time
for the collection procedure is identified (e.g., based primarily
upon donor time availability). One potential inlet flow to the
system is derived from at least this identified total procedure
time. Another potential inlet flow to the system is derived which
provides an "optimum" collection efficiency and is effectively the
apex of a bell-shaped yield/inlet flow curve (i.e., the inlet flow
which provides the maximum blood component yield). Consequently, if
the total procedure time-based inlet flow is greater than the
maximum yield-based inlet flow, and thus is an inlet flow on the
decreasing slope portion of the yield/inlet flow curve, the maximum
yield-based inlet flow magnitude is used in the performance of the
collection procedure. However, if the total procedure time-based
inlet flow is less than the maximum yield-based inlet flow, and
thus is an inlet flow on the increasing slope portion of the
yield/inlet flow curve, the total procedure time-based inlet flow
magnitude is used in the performance of the collection
procedure.
[0037] The subject invention provides greater efficiency in blood
component collection and management. For example, the present
invention can be used to compare blood bank/center component
inventories with projected needs, and adjust collection procedures
to meet these needs. Further, the present invention provides
benefits to donors. In particular, certain information relating to
the donor's physical and medical characteristics may be stored in
the system and utilized during subsequent visits by the donor to
derive magnitudes for the various process control parameters. For
example, for a donor with an anticoagulant intolerance, the
magnitude of the anticoagulant infusion rate may be set so as to
not exceed the donor's tolerance.
[0038] The present invention may be implemented as a computer
process, a computing system or as an article of manufacture such as
a computer program product. The computer program product may
include a computer storage medium communicatively connected to
and/or readable by a computer system and may include encoding of a
computer program of instructions for executing a computer process.
Such a computer program product may also be a propagated signal on
a carrier readable by a computing system and may also include
encoding of a computer program of instructions for executing a
computer process.
[0039] These and other features of the present invention can be
better understood from the following detailed description of a
preferred embodiment of the present invention taken in conjunction
with the accompanying drawings, which are briefly described

DETAILED DESCRIPTION OF THE INVENTION
[0056] The present invention will be described with reference to
the accompanying drawings, which assist in illustrating various
pertinent features hereof. One application of the present invention
involves one or more blood component collection systems which
separate, remove, and collect at least one type of blood component
(e.g., platelets, red blood cells, stem cells, white blood cells,
plasma) from a source of whole blood (e.g., a donor) through
utilization of a collection procedure derived from a typically
site-configured and/or operator-input goal or set of goals and may
optionally also include a "maximization" of at least one process
control parameter. This type of maximized parameter derivation is
referred to herein as an "optimization process" and the derived
process control parameters may be referred to herein as "optimal
values."
[0057] Referring to the schematic of FIG. 1A, a first alternative
schematic representation of the present invention is shown as
including a blood component collection and information management
system generally identified by the reference numeral 2. The system
2 would typically be implemented at a blood bank/center (not shown
in FIG. 1A). The system 2 may include a substantially centralized
computing/data storage assembly 140 (e.g., including an appropriate
microcomputer and/or microprocessor such as a Windows-based
standard desktop or laptop computer (or other like platforms),
including therein or communicating with at least one memory device,
not shown separately in FIG. 1A, with corresponding appropriate
software, etc.) and at least one blood component
separation/collection assembly (three shown), each generally
identified with respective reference numerals 10 (in FIGS. 1A-1 D).
Each such separation collection assembly 10 preferably includes a
blood component separation and collection device 18 as an integral
part thereof. As will be discussed below, the centralized
computing/data storage assembly 140 (or at least a portion thereof)
and the associated blood component collection assemblies 10 are
preferably appropriately interfaced with each other in electronic
or electro-magnetic data communication relationship as will be
described, but may also and/or alternatively be disposed in a
physically separate disposition from each other particularly during
non-communication operation. That is, component
separation/collection, data communication, retrieval, manipulation,
and optimization procedures in accordance with principles of the
present invention are not limited to being performed at any
particular physical location of apheresis machines 10 relative to a
central assembly 140. Furthermore, data entry, manipulation and
storage may still be performed at/on each machine 10 using, for
example, respective interfaces, which here are shown as preferred
touch screen input/output devices 199.
[0058] A further aspect of the present invention is shown in more
detail in FIG. 1B wherein a centralized computing/data storage
assembly 140 is shown schematically disposed in communicative
relationship with various types of blood component collection
machine assemblies 10 as well as to either a discrete blood center
information system within a blood center 1000 or a hospital
information system within a hospital 1001, or both. Thus, as will
be described in further detail below, a centralized computing/data
storage assembly 140 may preferably make broad use of multiple
communication connections (including satellite and/or wide area
networks (WAN's), for example). Note also that though preferable
connections to Trima apheresis machines 10 (available from the
assignee of the present invention) are shown and described
throughout; these are intended as exemplars only. As shown in FIG.
1B, connections can be made to numerous other machines as well,
such as COBE (Trademark) Spectra apheresis machines and/or Baxter,
Inc. and Haemonetics Corporation apheresis machines (such as the
CS-3000, the Amicus and the MCS+ apheresis machines, inter alia).
The currently preferred machines 10 are, as shown, Trima apheresis
machines 10 (see e.g. FIGS. 1A-1D). However, a representation of a
COBE Spectra apheresis machine is also shown in FIG. 1B, identified
therein generally by the reference numeral 10A, and a Baxter Amicus
machine and a Haemonetics MCS+ machine are also shown in FIG. 1B
and identified by the respective reference numerals 10B and 10C.
Use with a more traditional manual whole blood collection system is
also shown schematically in FIG. 1B, generally identified by the
reference numeral 10D, therein. Thus, this system is intended to
and will operate with various apheresis as well as whole blood
collection systems.
[0059] Generally, a centralized computing/data storage assembly 140
may include, as shown schematically in FIG. 1A, a central station
148 which may include, for example, data input/entry devices
generally identified by the reference numeral 149. Such devices 149
may, more particularly, include a keyboard 149A, a mouse 149B,
and/or if desired, devices such as a barcode reader (not shown),
and/or a digital camera (not shown) and/or an input/output display
monitor and screen 200 as these may be known in the art. Various
internal hardware and software elements, again as known in the art
are also intended to be included within a central station 148.
Further, the centralized computing/data storage assembly 148 may
include a data manipulation device 144 (disposed within station 148
in FIG. 1A), which is preferably closely associated with and in
some embodiments is perhaps inseparable from the central station
148. Manipulation device 144 may be an appropriate processor as
used in a computer system such as may be used in a microcomputer or
otherwise standard desktop or laptop personal computer (PC)
including a preferably Windows-based operating system and may
further include other devices and attendant manipulation software
(whether resident on/in the processor or resident in other
associated memory devices but closely associated with the
processor). A further preferred element of the computing/data
storage assembly 140 is the storage medium 142 (not separately
shown from central station 148 in FIG. 1A) used for data storage.
The storage medium 142 may also be closely associated with the
other elements of the assembly 140, i.e., the central station 148
and the manipulation device 144, or as with those other devices it
may be dissociated in physical space but communicatively associated
therewith through space (via cabling or energy wave communications,
inter alia), so long as these elements cooperatively interact
functionally. Hardware and software which may make possible data
communication between various elements of assembly 140, as well as
between assembly 140 and myriad possible external devices, some of
which are like those shown in FIGS. 1A and 1B, are hereafter
referred to as a communication or server subsystem 146. Subsystem
146 may also be mainly disposed on or in the assembly 140 and/or
may be mostly physically disparate therefrom so long as it provides
the data communication functions described herein.
[0060] Thus, the assembly 140 may be referred to as a whole for
performance of the inputting and maintaining of donor-related data
functions (principally through use of the central station 148,
communication subsystem 146, and the storage medium 142), and also
typically for the preparation of an initial procedure order (the
process control parameters derived from the donor-related data and
other considerations) for a given donor (through use primarily of
the data manipulation device 144 together with the data obtained
from either or both of the other elements 148,142 as communicated
by and through the subsystem 146).
[0061] Though perhaps not preferred, there may remain various
situations in which it may be desirable to maintain the ability to
perform data entry and/or manipulation procedures/functions at the
corresponding pre-existing operator interface 199 of each
particular apheresis machine assembly 10 as well. In such
situations, a central computing/database assembly 140 may thus not
be required for operation of assembly 10 even if still provided.
Note in the preferred apheresis machines 10 shown in FIG. 1A (such
as the Trima machines 10 described above), the computing/database
and data entry and manipulation capabilities are available in and
would thus be able to continue to separately provide these
functions, if desired. Moreover, this could still occur even when
connected through a central communications system 146 to a central
assembly 140 such that the computer/database assembly 140 may still
collect/retrieve data from the one or more apheresis assemblies 10
even if the central assembly 140 is not used to program the
respective machines 10. However, where a central computing/database
assembly 140 is employed as preferred herein, this donor-related
data and/or initial procedure order is preferably generated by the
central computer/database assembly 140 and then transferred to one
of the apheresis machines 10 (via an RS/232 or other similar
interface, among other communications options such as energy wave
communications, inter alia (see further descriptions below)). In
either event, the operator is preferably provided with one or more
data manipulation or optimization options, whether through the
central data manipulation device 144 of a centralized
computing/data storage assembly 140 or the data manipulation
capabilities of the apheresis machines 10 themselves. Note the data
manipulation and/or optimization options provided by a central
assembly 140 may provide a different set of process control
parameters than an initial procedure order that might result from
data entered manually on the apheresis machine 10 because the data
manipulation and/or optimization on a central assembly 140 may be
based upon one or more previously specified and central database
stored conditions/goals (e.g., input blood component yield, input
procedure time) and one or more particular derivations for the
process control parameters. Generally, more flexible options would
be available from a central server system 140 than those previously
available on discrete machines 10. Moreover, if an optimization
option is selected at the central server 140, a manually-entered
procedure order may be modified to reflect the results of such an
optimization and the collection procedure may be initialized or
re-initialized with the results of the optimization (i.e., the
collection procedure could be re-initialized in the less preferred
case of an optimization which is performed after the collection
procedure has been started and such a case is referred to as a
downstream optimization). The collection procedure may thereafter
be performed by the respective blood component collection device
10.
[0062] The concept of optimization here generally refers to
achieving the maximum or best product output depending upon certain
circumstances (e.g., obtaining the most product in a certain
specified time or achieving a specific yield in the fastest time).
On the other hand, the concept of data manipulation is more
generally here intended to have a similar yet less exacting
connotation, such that perhaps the best or maximum output may, but
will not necessarily be the result. Thus, data manipulation is here
intended to encompass optimization calculations in addition to
providing perhaps less than optimum but still high efficiency
results depending on certain further combinations of criteria.
Thus, data manipulation is intended to generate more and/or perhaps
better options to the blood donation center. For example, blood
centers may prefer or determine to require certain combinations of
products from certain blood type donors 14 (see FIG. 1B); then the
blood center 1000 can prioritize this in the computer/database 140
so that those donors will donate those combinations even if the
particular yields or donation times are not fully optimized
according to the concept of optimization set forth above. Thus,
yield or time optimization can be made secondary to other data
requirements and/or manipulations. Note also that optimization
and/or manipulation may be performed without requiring the central
system 140 to collect/retrieve data from the various apheresis
assemblies 10. Thus, communications may be made only one-way to (or
from) the apheresis assemblies 10. Further, a preferred purpose for
performing the optimization and/or manipulation functions centrally
is to allow selection of the donation procedure prior to connection
of a donor to a machine 10; thus, a particular product or products
and the corresponding tubing set (if there are distinctive such
sets) may be selected prior to machine set-up and donor connection.
Also it could prove that the donor may not be able to provide a
useful donation (for the end recipient/patient 15; see FIG. 1B),
and this could thus be determined prior to machine set-up and/or
donor connection.
[0063] Nevertheless, before describing the preferred
manipulation/optimization processes of the present invention in any
further detail (see description relative to FIGS. 7-1 0, below),
two further, non-exhaustive alternative system embodiments will
first be described. Referring first to FIG. 1C, an alternative
centralized computing, communication and data storage assembly 140A
is shown. Assembly 140A includes a central station, here referred
to as a central data server 148A, which may be substantially like
the central server 148 in FIG. 1A, at least preferably in primary
function. At least a storage medium/database 142A and preferably
also a data manipulation device 144A, each again substantially like
those described relative to the embodiment of FIG. 1A are also
preferably disposed within the central server 148A of FIG. 1C.
However, in the embodiment of FIG. 1C, the communication sub-system
identified generally by the respective reference numerals 146A and
146B, is shown as preferred here discrete therefrom, in two general
sub-parts, referred to respectively as the machine network 146A and
the client network 146B.
[0064] Machine network 146A preferably includes a network terminal
server 1210 with a connection 1212 between the server 148A and the
terminal server 1210. Respective connections 1215 are also shown as
disposed between terminal server 1210 and each of the
separation/collection machines 10. Connections 1212 and 1215 may
typically be RS/232 cable-type connections, or other alternative
data communication connections may be used including such options
as radio, microwave or other electromagnetic wave communication
systems (not specifically shown). Note that other
separation/collection machines/systems, such as systems 10A, 10B,
10C and 10D (from FIG. 1B) may also be connected to/through the
illustrated terminal server 1210 or a further discrete server (not
shown).
[0065] A similar, though preferably discrete, network terminal
server 1220 is also shown in FIG. 1C to illustrate a preferred
communication sub-system for the client network 146B. A connection
1222 between the central server 148A and the terminal server 1220
is also shown, as are respective connections 1225 from the terminal
server 1220 to one or more data input/output/manipulation stations
149C (two shown here). Connections 1222 and 1225 may here also
typically be RS/232 cable-type connections, or take other data
communication forms including, for example, energy wave
communication forms. Note also that other devices (not shown) might
also be connected or connectable to/through the illustrated server
1220, as for example, one or more printers (not shown) or other
accessory devices. Note, stations 149C may contain, as above, one
or more various input/output devices such as keyboards, mice and/or
screens (as shown) or otherwise (barcode readers, digital cameras,
etc., not shown). Moreover, as decentralized stations, these
assemblies may also generally include computing devices and/or
capabilities such as may be included in standard desktop or laptop
computers, including the stations 148B as shown, and potentially
data storage/memory and/or data manipulation devices and/or
software along with potential resident communications devices
and/or software.
[0066] Separating the machine network server 146A from the terminal
network server 146B allows for isolating and/or protecting
communications therebetween, as may be desired. Thus, the
respective servers may have on one side, a network connection to
the central server 148A using discrete I/P (Internet Protocol)
address information, and on the other side, RS/232-type connections
to the respective end devices (machines 10, and/or input/output
devices 149C, e.g.). In this fashion then, each network may be kept
private from each other such that the I/P's are essentially hidden
from each other by the central server 148A. A firewall
communication protection setup as known in the art may thus be
established.
[0067] A further alternative communication sub-system 146C is shown
in FIG. 1D. Sub-system 146C generally includes a network terminal
server 1230 with respective connections 1232 which connect
respective central servers 148C to network terminal server 1230.
RS/232 or other communication connections (as above) may be used
here as well. In this way, two or more centralized servers 148C may
communicate data with each other. Thus, central servers in two or
more physically separate clinics may communicate with each other.
Such a system may also be used for communication with other
information systems (blood center information systems or hospital
information systems) such as is schematically shown in FIG. 1B.
Other similar communications can also be made in this way, as for
example to help or maintenance centers (not shown), as described
below. Firewall types of communication protections may also be set
up here, such as was described above. Thus, network connections can
be made between each central server 148C and the network terminal
server 1230; whereas RS/232-type communications can be established
elsewhere. Note, all variations of system 140 may include
communications connection(s) of many different sorts, which allow
each particular device to communicate with other devices. RS/232
communications connection(s) as described, are only examples of
such communication media. Communication media may typically embody,
be embodied in or otherwise be capable of interacting with and/or
through computer readable instructions, data structures, program
modules or other data in a modulated data signal such as a carrier
wave or other transport mechanism and include any information
delivery media. The term modulated data signal may include a signal
that has one or more of its characteristics set or changed in such
a manner as to encode information in the signal. By way of example,
and not limitation, communication media may include wired media
such as a wired network or direct-wired connection, and wireless
media such as acoustic, RF, infrared and other wireless media. The
term computer readable media as used herein preferably includes
both storage media and communication media.
[0068] A more detailed description of the preferred steps for using
the present preferred system will now be set forth. In FIGS. 2A-2I,
inter alia; use of the centralized computing/data retrieval
assembly is shown in more detail. First, FIG. 2A depicts an
exemplary display page or screen 201 which may be the first such
screen displayed on the output monitor display screen 200 (see,
e.g. FIG. 1A) of the centralized computing/data storage assembly or
system 140 when the software thereof is initially accessed. A more,
rather blank, screen (not shown) may be used as an initial screen
upon startup, as described below. As can be seen in display screen
201 generally, the initial donor information may be gathered here,
such as for example the donor's name (last and/or first), and/or
the donor's identification (ID) number or like identifier (if
used), and/or the donor's telephone number or other identification
data (also if used, not shown). Data entry fields for these types
of data may be seen in the main work area 202. These are several
examples of possible initial identifiers among numerous others,
which could be alternatively substituted herein.
[0069] Moreover, as mentioned this could be the first display
screen to be shown upon software initialization, or other
alternatives (not shown) could be simply used preliminarily hereto
by way of introduction to this or a like display 201. In any event,
some display is preferably used as the starting point for data
entry (and/or search, if the data were previously entered or
imported from another system) for use with a particular donor, and
for the sake of convention, display 201 will be used in this role
for this description of the preferred embodiment. Note also, that
as shown in FIG. 2A, disposed next to the main work area 202 (with
sub-areas 203 and 204 as will be described below) is a procedure
icon selection area 205, which is depicted along a vertical portion
of the left-hand side of display 201. In it, five icons 207, 208,
209, 210, and 211 are currently shown, though either more or fewer
such icons could be used as may be desired.
[0070] A description of the preferred general overall procedural
flow will be set forth starting with particular reference to the
procedure icon bar 205 on the left side of the display screen
201.
[0071] As an initial step or sub-procedure, the Select Donor icon
207 represents the performance of several functions generally
described as follows. First is a Greet Donor function wherein the
system operator may verify and/or add a new donor record to the
system database 142, and check-in a donor into the system 140
(either by data entry directly into this application or via
automatic transfer of data from a discrete blood bank information
system). Thus, the operator may perform Donor Entry/Edit functions
to enter or modify a donor record in the database (see e.g., FIGS.
2B-2I, as described below). This may also include capturing a donor
image using a digital camera to take the donor's photo (this
functionality may also or alternatively be part of the Prepare
Procedure Wizard process; see below). And, this may include use of
a barcode reader to enter bar-coded data such as the donor ID, etc.
(Note: this data input functionality may also be part of other
processes in this system such as the Prepare Procedure Wizard
(entering bar-coded unit number) and/or the Finalize Procedure
Record (entering bar-coded lot number/data for supplies).)
[0072] After the data entry/verification, the next general step
would preferably be to Prepare the Procedure for component
collection as indicated by the second icon 208 in bar 205 as shown
in FIGS. 2A and 3A, inter alia. This preferably involves using a
Prepare Procedure sub-procedure or software wizard to record
further donor information and select the procedure to be run on the
donor prepared as set forth above (see description relative to
FIGS. 3A-3F, below).
[0073] Next, the operator preferably uses the Assign Machine icon
209 to access the sub-procedure for assigning the donor to a
particular apheresis collection system 10. More details of this
process are described below with particular respect to FIGS. 4A and
4B.
[0074] As shown generally in FIG. 5A, the central system 140 may be
used for monitoring the procedure/machine status after the
assignment of a donor to a particular machine. An icon 210 (FIGS.
2A and 5A) is preferably included for accessing this functionality
in the left-hand procedure icon area 205. Screen 501 (FIG. 5A)
reflects the first step in such a monitoring sub-procedure.
Finalization of the Procedure Record may also be performed here,
wherein the operator may enter procedure data, including operator
roles and supplies entries. (Note: this record finalization
functionality may also be part of the Select Procedure process
below.)
[0075] Another optional step in the overall procedure shown in
FIGS. 2A and 6A by the icon 211 is the Select Procedure
sub-procedure where the operator may search for and select a
procedure (either active, pending, or finalized). A screen 601 such
as shown in FIG. 6A may then be displayed (as described in further
detail below). The operator will then be able to enter lab results
by entering procedure product volume/quality information returned
from the lab. The operator may finally prepare a Report on the
Procedure by generating procedure or donor or production
reports.
[0076] It ought to be noted that the various sub-procedures
identified by the respective icons 207-211 can be selected at any
time in the overall procedure to view, input or modify particular
desired information. As an example, but not to be considered in any
way as a limitation, the assign machine icon 209 could be selected
at anytime to view the list of available and/or assigned machines
10. However, it should be noted that certain functionalities may
thus be unavailable if an icon 207-211 is selected without having
completed a previous sub-procedure. For example, upon selection of
the assign machine icon 209 as suggested here, the assignment
function will not be available unless at least one donor has been
processed though the Prepare Procedure sub-procedure (see
description, below). In such a case, where no donor has yet been so
processed, there would not appear any donor icon in the donor
assignment queue of screen 401 (FIG. 4A), even if the available and
assigned machines 10 may be shown in the machine list. Similar
functionalities preferably requiring pre-completed sub-procedures
(thus building on previous module completions) are identified
throughout the below descriptions.
[0077] Although not a part of the general run procedure (and thus
not involving or resulting from the clicking of icons in the
procedure icon area 205), Administration Tasks (extra security
being preferably required to access these options) may generally
include: Setting Up the Application including setting default
values; setting the apheresis machine configuration(s) including
creating and/or modifying apheresis collection system
configurations; Defining Products including establishing an
unlimited number of product definitions; Defining Procedures
including establishing an unlimited number of procedure definitions
(combinations of product definitions); Defining Focus Lists
including establishing an unlimited number of procedure focus lists
(prioritization of procedure definitions); Performing Database
Administration including managing and maintaining the data stored
within the central database; and Blood Product Prediction wherein a
blood product forecasting report may be generated.
[0078] Returning now to FIG. 2A, a more detailed description of the
preferred overall procedure will now be set forth. In an initial
start-up mode of software initialization, the main work area 202
could be adapted to display a preliminary display screen (not
shown), which has no active workspaces. Then, after log-in (see
below), the operator could be forced to select an icon from a menu
list and/or from the left-hand procedure icon selection area or bar
205 in order to initialize the overall procedure. As an example,
the operator could first select the select donor icon 207 with a
computer screen cursor or pointer (not shown) and click the "enter"
or mouse button (neither shown) as is known in the art of standard
desktop or laptop computer, Windows-based or like software
applications. This selection could then bring up the shown display
201 for beginning a donor check-in procedure. A few further
alternatives for use in start-up (as well as throughout operation)
may be found in the toolbars located as shown horizontally along
the upper portion of the display 201. These are toolbars much like
those used in a plurality of computer Windows-type software
applications with numerous functional similarities and specific
distinctions as described herein. For example, the software
start-up to the initial working display may also be achieved by
selecting the "Tasks" menu heading 216 in the top level menu
toolbar 215 and then selecting the appropriate "open" file command
(not shown) or other like commands as are generally known in the
art. Or, similarly, a small icon toolbar 217 may be configured to
be used for initiating software procedures, as may also be
generally known in the art. Other menu headings and/or icons (not
shown) in toolbars 215 and/or 217 (or otherwise, not shown) may be
used for other functions in startup or otherwise.
[0079] A third toolbar 220 may further be used in or even prior to
software initialization or it may not be opened until the main work
area 202 has been opened. The third toolbar 220 as shown and
preferred herein has a location for the typing of a name or other
identifier which may be used to begin the process of either data
entry for new records or a search for existing records. This third
toolbar 220 is preferably used for identifying the operator of the
system, such identification being useful for logging-in and/or
assessing the operator's level of security clearance, inter alia
(described below). Thus, it is preferred that this operation of
logging-in the operator be completed first. Further, it is
preferred that a system administrator have previously established
authorized users, with log-in names and optional passwords. The
log-in names may then be typed in the blank space in tool bar 220,
or the down arrow may be selected and clicked to reveal the list of
authorized users to be selected. Once a user log-in name is
entered, then a pop-up dialog box/window (not shown) may be made to
appear to prompt entry of an appropriate password. Note, password
and/or user log-in names may be made editable via such a pop-up
dialog box/window (not shown) or may be restricted to editing by a
system administrator. Further similar options may also be used for
these initialization procedures as may be known in Windows or
Windows-like environments.
[0080] Returning now to the main work area 202 of the display
screen 201, two sub-areas 203 and 204 are shown in which data may
be entered or displayed. First, as shown in sub-area 203, data
concerning the identity of the donor to be checked-in may be
entered in order to begin the donation process. The
computer/database system 140 may then be made to search its
database 142 (by selection of the search button 218 by the
operator) to determine whether this particular donor has been
previously entered in the system. If so, the system 140 returns the
results of that search in the search results sub-area 204. Note
that the search may be made dependent on any of the criteria set
forth in the first sub-area 203 (or others not shown herein but
alternatively usable herewith). Also, the search mechanism may be
adapted to search wild cards and/or truncated terms or list various
short forms for further search as these and other search
capabilities are known in the art. As such, when typed into the
proper field, this display screen simply calls up a donor from the
existing database if such a donor exists therein. A search/query
format may be used wherein typing an alphabetical initial will call
up into the results window 204 all donor names beginning with that
initial. The operator may then double click on a listed name to
select and call up the next preferred screen (see FIG. 2B, the
donor entry/edit screen 221), which contains greater detailed donor
information as will be described below.
[0081] First, however, several other graphical buttons are shown in
the main work area 202 of FIG. 2A and may be used to perform
various functions. For example, below the work sub-area 204 are
examples of three buttons, which could be set forth on this or any
other alternative display screen used herein. In this example, the
three buttons here are the "new" button 212, the "select" button
213 and the "help" button 214. The "new" button 212 could be used
to toggle to a fresh search page like this one 201 shown without
any information in any of the fields (name, ID, or results).
Alternatively, the "new" button 212 could allow for either new data
entry editing directly in the fields shown here in screen 201, or
could be used to call up a secondary display screen, such as the
Donor Entry/Edit screen 221 shown in FIG. 2B (described below).
Such a "new" screen would preferably have empty fields to allow for
new donor information data entry. Note, the "new" button 212 is
shown in active, darkened mode in FIG. 2A as compared to the other
"grayed-out" buttons 213 and 214. This means it is active as shown
(and as would be understood to those knowledgeable in the art of
common, conventional Windows and the like software applications).
It is active as shown when it may be desirable to enter new data
records into the system. The "grayed-out" "select" button 213, on
the other hand, is inactive until a search result record is
displayed in sub-area 204. When such a record is made available,
button 213 would be made active and darken in style such as the
other active buttons shown here. The "select" button 213 provides
for the selection of a donor data record to be verified and/or
modified for preparation of a collection procedure. This
functionality as well as that of the "help" button 214 is described
in greater detail below.
[0082] As next shown by the donor data entry/edit screen 221 in
FIG. 2B, data can be either manually input into the
computer/database system 140 by typing into the corresponding
fields such as will be described further below. Or, any appropriate
data input can be performed with an alternative input system such
as, for example, a bar code reader (not shown), or input from other
computerized information systems as will be described below and/or
become obvious to those skilled in the art. If using a bar code
reader, a donor may be given a donor identification (ID) card which
may have a bar code imprinted thereon which represents that
particular donor's data. Then, an optical reader (not shown) can be
used by the operator to read the bar code information from the card
to fill in the donor data fields shown in FIGS. 2B-2I. The other
previously introduced alternative input process would be in taking
advantage of other pre-existing database/information systems which
may already contain the appropriate donor data. Thus, the present
computer/database system 140 may be disposed in data communication
relationship with one or more such pre-existing systems and simply
upload the desired data therefrom. Thus, the fields such as those
shown in FIG. 2B, et al., can be automatically populated from the
blood center's management information system (e.g., Wyndgate, MAK,
etc.). In this situation, the reception portion of the data entry
process (i.e., initial data entry and/or verification) could take
place entirely on the blood center receptionist's computer in the
corresponding Wyndgate or MAK (or like) system. This information
may then be retrieved by and/or forwarded to the computer/database
system 140 to populate the fields such as those shown in the
display 221 of FIG. 2B. This display 221 may be referred to
hereafter as the Donor Entry/Edit screen 221 and may, in the
three-room model, initially be called up in what may be referred to
as the "Reception" room. This three-room model will now be briefly
described.
[0083] There may be considered three main data input/verification
points in a collection process. At the first point, hereafter
referred to as "Reception," the donor is checked into the overall
process. Under a scenario of data connectivity between the central
computing/database system 140 and a blood bank information system,
the "Reception" room/step may be handled through the blood bank
information system and the needed donor data may then be
automatically transmitted (downloaded or uploaded or otherwise)
into the central system 140 as described above. With this
connectivity between the blood center information system and the
central system 140, the historical donor data (which may be batch
file loaded into the central system 140 periodically) may also be
called up and the donor may then be assigned to the second room,
hereinafter also called the "Screening Room." In the screening room
the donor information may be retrieved and displayed and several
preferable pieces of lab data may be input for purposes of
selecting the proper/preferred collection procedure to be
performed. A donation unit number may also be assigned at this
point. The central system 140 may, but preferably does not, hold
confidential donor information influencing potential deferral; this
information would preferably reside only in the blood bank
information system. The central system 140 is preferably only
concerned with the collection process. In either the "screening
room" or the third room, hereinafter also called the "Donation
Room," the donor may be assigned to a particular apheresis machine.
The procedures performed in the donation room may also include
recording other data about the procedure such as recording the
identification numbers associated with the disposable tubing set.
Once the donor is assigned to a machine, the central system 140
would preferably go into a monitor-only mode relative to that donor
and that machine for monitoring and/or recording any and/or all
events in the procedure. More details hereon are provided
below.
[0084] Returning to the donor entry/edit screen 221 of FIG. 2B,
further details concerning some of the specific, preferred fields,
tabs, buttons, etc. shown on screen 221 in FIG. 2B will now be set
forth.
[0085] As mentioned, new donor records may be created using screen
221, and pre-existing records may also be edited/modified here. A
primary difference in creating new records versus modifying
existing ones lies in the fact that the fields shown in FIG. 2B
will be empty prior to entry of new record information, as opposed
to having been populated by previously entered (or imported) data
in the modification sense. As shown in FIG. 2B, the data fields are
primarily populated thus generally signifying either a data import
or previous donor record entry situation.
[0086] Primarily donor identification data/information, such as the
donor's name and/or ID, may be entered/edited in the fields
disposed preferably in an upper substantially fixed area 222 of
screen 221. However, if this data has come from a previously
entered record, the fields in area 222 are preferably "inactive" as
shown by being "grayed-out." Thus, these fields would preferably
not be editable directly, rather would be editable otherwise as
described below. Other information about a particular donor may
then be entered/edited in corresponding fields appearing with
respective tabs in the lower data area 224. For example, donor
demographics information may be entered/edited in corresponding
fields under the "Demographics" tab 231 as shown in FIG. 2B. Other
general information such as gender or date of birth, inter alia,
would preferably be enterable/editable under the "General" tab 241
(see FIG. 2C). Blood type, CMV, (cytomegalovirus) and HLA (Human
Leukocyte Antigen) type, inter alia could be entered/edited under
the "History" tab 251 (FIG. 2D). A "Comments" tab 261 (FIG. 2E)
could be selected and used for entry of comments about the donor.
Allergy information could be entered or edited under an "Allergies"
tab 271 (see FIG. 2F). Donor status data could be entered and/or
edited under a "Status" tab 281 (FIG. 2G) including such data as,
for example, last procedure date, numbers of donations given, over
what period of time, etc. Other tabs, such as a "Blood Loss
History" tab 291 (FIG. 2H) and/or a "Procedure History" tab 299
(FIG. 21) could also be used for separate entry of such
information. Note, separate pop-up dialog boxes or other
alternative screen styles or types (none shown) may be used for
prompting for and entering/editing these types of information.
[0087] Note, the information shown and described here in screen 221
may alternatively be optional or mandatory, depending on the
desires of the ultimate user; here, usually a blood center. That
is, the standard operating procedures (SOP's) of the blood center
may be implemented herein to make certain information optional or
mandatory, as desired. However, certain information, whether listed
here (under the Donor Entry/Edit screen 221) or entered elsewhere
(see the Prepare Procedure functionality, described below) may be
required by the blood separation/collection assembly 10 prior to
initiation and/or completion of a separation/collection procedure.
Examples of such information may be gender, height, weight, blood
type, and/or pre-count (platelets and/or hematocrit) information
(again, see the Prepare Procedure, below). As such, some of this
information (e.g., height/weight) would only be enterable/editable,
as preferred here, in the procedure preparation portion of the
overall process (see below).
[0088] Moreover, as introduced above, all, most, or at least the
information required by the blood center may be entered or have
been entered previously into the blood center's separate (but
communicatively-linked) information system (not separately shown,
but see FIG. 1B). Such an information system is separate from the
present invention, although these systems may be made to
communicate with each other. Thus, such information may be entered
into the blood center information system, preferably according to
the standard operating procedures (SOP's) of the blood center, and
then this information may be transferred (downloaded or uploaded,
or otherwise) to the central system 140 of the present invention.
This information would then populate the respective fields shown
and/or described here relative to the Donor Entry/Edit screen 221.
An operator of the present system may then use screen 221 to merely
verify the accuracy and/or completeness of this information shown
on screen 221 prior to checking-in the donor for the present
collection procedure.
[0089] In a presently preferred embodiment, when a blood center
information system is used, the transmission of this general sort
of donor identification, demographics and commentary information,
inter alia, is one-way from the blood center information system to
the central server system 140 of the present invention, primarily
to maintain SOP's on which types of donor information a blood
center may wish to capture. Thus, the operator may continue to
operate at reception in a fashion unchanged from before
introduction of the present invention.
[0090] Nevertheless, these donor identification data may also be
transmitted both ways; namely, from the blood center information
system to the central server 140 and/or back to the blood center
information system from the central server 140. In such an option,
these data may be entered/edited in either system and then be made
to update the records of the other system. Note, these donor data
communications are discussed here only in terms of the general
donor data; not necessarily including feedback information about
the results of any particular collection procedure. Such procedural
data communications are also considered within the present
invention, but are discussed further below.
[0091] First however, more particular descriptions of the preferred
data to be entered/edited in screen 221 will now be described.
[0092] As mentioned, in the Demographics tab 231, the operator may
enter/modify the donor's national ID, address and telephone number
as shown in FIG. 2B. Then, after selecting the General tab 241, the
following information may preferably be entered/edited: Gender
(Male or Female, neither of which preferably selected by default);
Date of Birth (which can be typed in text box or selected using
pop-up calendar); Ethnic Background (preferably available via a
drop-down list which is editable by selection only, and is
preferably created by the System Administrator); and Donor Picture
(the default is preferably a generic, genderless icon; however, if
a gender is selected using one of the Gender radio buttons, this
icon preferably changes to a gender-specific icon the next time the
donor record is accessed, provided the operator saved the data
before closing the dialog box). The operator can optionally click
Update Picture to take donor's photo using an optionally attached
digital camera.
[0093] The operator may then optionally click the Donor History tab
251 (FIG. 2D) to view/modify procedure history data for this donor.
This tab 251 may contain the following information: Blood Type,
CMV, HLA, Hematocrit, and/or Platelet Count. More specifically, the
Blood Type may include A+, A-, B+, B-, AB+, AB-, O+, O-, or
Unknown; preferably accessible via a drop-down list, editable by
selection only; default is preferably Unknown. The CMV Status
includes Unknown, Positive, and Negative Radio buttons options; the
default is preferably Unknown. HLA Typing options are as follows:
the operator may select the HLA Tested check box if HLA testing has
been done for this donor; or left unchecked by default. And the A,
B, C, D check boxes are disabled unless the HLA Tested check box is
selected. Once HLA Tested is selected, the operator can select one
or more HLA-type check boxes (A, B, C, and/or D). The Last
Hematocrit and the Last Platelet Count are preferably non-editable,
generally pre-populated fields from past procedure data or external
blood bank information system, if available.
[0094] The operator may then also optionally click the Comments tab
261 (FIG. 2E) to enter/view free-form comments about the donor. To
add a comment, the operator clicks the Add Comment button 262. A
separate Enter Donor Comment pop-up dialog box (not shown) may then
appear, or comments may be made enterable/editable within the work
space 263, shown. The operator may then enter a comment in the text
box. Note that a comment is preferably not saved in the donor
record until the operator clicks the Apply or OK button 229 or 230
in the Donor Entry/Edit dialog box 221 (see more details
below).
[0095] The operator may then optionally click the Allergies tab 271
(FIG. 2F) to enter/view donor allergies and associated comments. To
view the comments about a specific allergy, the operator clicks the
allergy in the Donor Allergies list; associated comments for this
allergy appear in a Donor Allergy Comment box. To add an allergy,
the operator may click the Add Allergy button. An Enter Donor
Allergy pop-up dialog box (not shown) may then appear. A listing of
allergies (preferably non-editable and created by the System
Administrator) may be made to appear in such a dialog box and the
operator may optionally enter a comment pertaining to that allergy
in the Allergy Comment box. Note that an allergy is preferably not
saved in the donor record until the operator clicks the Apply or OK
button 229 or 230 in the Donor Entry/Edit dialog box 221 (see
details below).
[0096] The operator may also decide to remove an allergy from the
Donor Allergies list. The operator may then click the allergy in
the Donor Allergies list, and then click the Remove Allergy button.
The allergy is removed from the displayed list; however, the
allergy is not permanently removed from the donor record until the
operator then clicks Apply or OK button 229 or 230. The operator
may decide to enter additional comments for an allergy currently in
the Donor Allergies list. The operator clicks the allergy in the
Donor Allergies list, and then clicks the Add Comment button. An
Allergy Comment dialog box (not shown) may be made to appear. The
operator can then enter a comment and click an OK option. The Donor
Entry/Edit dialog box 221 reappears, still showing the Allergies
tab 271 (FIG. 2F). The allergy listing in the Donor Allergies list
is updated to show the new comment. The date and time the comment
was created, as well as the user ID for the user who was logged on
when the comment was created, will preferably appear with the
comment in the Donor Allergy Comment box.
[0097] The operator may then optionally click the Status tab 281
(FIG. 2G) to enter/view the following donor status information:
Donor Status--Active or Inactive; Donor Category (a drop-down list,
preferably created by the System Administrator); Donor Since
Date--date the donor started donating (preferably defaults to first
procedure date, if not modified, which can be typed in text box or
selected using a pop-up calendar); Last Visit Date--last date the
donor attempted to donate (defaults from system records, preferably
non-editable except by the System Administrator); Last Procedure
Date--the last date the donor actually did donate (default from
system records, non-editable except by the System Administrator);
Last Contact Date--last date that the center contacted the donor
(can be typed in text box or selected using pop-up calendar,
default is preferably the current date).
[0098] The operator may then optionally click the Blood Loss
History tab 291 (FIG. 2H) to view the total volume of blood the
donor has lost from apheresis (not whole blood) activities for the
previous 12-month period. All of the data in this tab is preferably
non-editable in this module. It is downloaded as run data from the
apheresis collection system 10 (preferably a Trima system 10) for
procedures run for this donor, and/or entered by an operator during
procedure finalization (see below). The tab 291 preferably shows
the Total Blood Loss the total volume (preferably in milliliters)
of blood the donor has lost from apheresis (not whole blood)
activities for the previous 12-month period); and a Procedure table
which shows blood loss for apheresis procedures for which a
procedure record exists in the central server system 140. Each
procedure is preferably listed in a separate row in the table. The
operator may need to scroll horizontally or vertically to view some
of the data. For each procedure, the table preferably shows the
following:
[0099] Procedure Date--The date the procedure was run.
[0100] Product RBC--The volume of RBC product collected during the
procedure (total RBC volume less anticoagulant volume). This
information is preferably determined based on the procedure that
was run and the donor's hematocrit.
[0101] Sample RBC--The volume of sample RBCs collected during the
procedure. This volume is either the default value set by the
Administrator during system setup or a value entered by an operator
during procedure finalization, according to the facility's SOPs
(see the Finalize Procedure Record description below).
[0102] Residual RBC--The volume of residual RBCs remaining in the
tubing set after the procedure. This information is determined
based on the tubing set type, the procedure that was run, the
donor's hematocrit, and whether or not rinseback was completed for
the procedure.
[0103] Other RBC--Any other RBC volume (for example, estimated
volume of a spill), entered by the operator in the Finalize
Procedure Information dialog box, Blood Loss tab, according to the
facility's SOPs. (see the Finalize Procedure Record description
below).
[0104] Product Plasma--The volume of plasma product collected
during the procedure (total plasma volume less anticoagulant
volume). The information is determined based on the procedure that
was run and the donor's hematocrit.
[0105] Sample Plasma (not shown in FIG. 2H; scrolled off the right
side of the screen)--The volume of sample plasma collected during
the procedure. This volume is either the default value set by the
Administrator during system setup, or a value entered by an
operator during procedure finalization, according to the facility's
SOP's (see the Finalize Procedure Record description below).
[0106] Residual Plasma (not shown in FIG. 2H; scrolled off the
right side of the screen)--The volume of residual plasma remaining
in the tubing set after the procedure. This information is
determined based on the tubing set type, the procedure that was
run, the donor's hematocrit, and whether or not rinseback was
completed for the procedure.
[0107] Other Plasma (not shown in FIG. 2H; scrolled off the right
side of the screen)--Any other plasma volume (for example,
estimated volume of a spill), entered by the operator in the
Finalize Procedure Information dialog box, Blood Loss tab,
according to the facility's SOPs. (See, the Finalize Procedure
Record description below.)
[0108] The operator may then optionally click the Procedure History
tab 299 to view product information for all procedures run for this
donor since the donor record was created in the present system 140.
The tab 299 shows product information only for apheresis procedures
for which a procedure record exists in the database 142. All of the
data in this tab is preferably non-editable. It is downloaded from
the apheresis system (preferably a Trima system) 10 run data for
procedures run for this donor. The operator may need to scroll
horizontally or vertically to view some of the data. For each
procedure, this tab 299 preferably shows the following:
[0109] Procedure Date--The date the procedure was run.
[0110] Platelet Yield--The yield of platelets collected during the
procedure.
[0111] Plasma Volume--The volume of plasma collected during the
procedure (plasma product volume plus anticoagulant volume).
[0112] RBC Volume--The volume of RBCs collected during the
procedure (RBC product volume plus anticoagulant volume).
[0113] Various alternative data entry/editing actions may also be
preferred. For example, at any time while using the Donor
Entry/Edit dialog box 221, the operator may click the Apply button
229 (see FIGS. 2B-2F, e.g.) to save all to-date changes to the
donor record, without exiting the dialog box. Similarly, at any
time while using the Donor Entry/Edit dialog box 221, the operator
may click the Cancel button 228 to cancel the current entry
session. The system 140 may then prompt the operator to confirm the
cancellation. If cancellation is confirmed, the system may lose all
unsaved changes and closes the Donor Entry/Edit dialog box 221. A
Help button 227 is preferably also provided to present a
corresponding help screen (not shown) when desired.
[0114] If the facility determines that a donor record no longer
needs to be in the central database 142, the record can be
permanently removed. This option is preferably only available when
an operator with a high level clearance such as a System
Administrator user role or the like is logged on to the system.
This Administrator or high level operator may then search for and
display the donor record in the Donor Entry/Edit dialog box 221, as
described and then click the Remove button 226 (see e.g., FIG. 2B).
A warning may first be made to appear, informing the operator that
the record will be permanently removed from the database 142. If
removal is still desired a Yes confirmation button (not shown) may
be selected. The following may then occur: 1) both the warning
message and the Donor Entry/Edit dialog box 221 may be closed; 2)
the Search Results box 204 in the Select Donor task window 201 (see
FIG. 2A) would no longer show a listing for the removed donor; 3)
the donor record would preferably be permanently removed from the
database; and/or 4) an internal record for this donor may be
retained elsewhere in the system for reporting reasons.
[0115] Moreover, at any time while using the Donor Entry/Edit
dialog box 221, the operator may change the donor's name, while
retaining the current donor ID. To do so, the operator would
preferably click the Edit Donor Name button 223 (see e.g., FIG. 2B)
in the Donor Entry/Edit dialog box 221. An Edit Donor Name dialog
box (not shown) would preferably be made to appear, displaying all
previous names used by the donor, as well as the date the name was
changed and the operator who was logged on to the system when the
name change was made. The operator may then enter a new name for
the donor in the Last Name, First Name, and/or Middle Name boxes,
and conclude with an OK option (not shown). The Donor Entry/Edit
dialog box 221 would then reappear, showing the changed name. The
operator can still also decide to not change the name by selecting
a Cancel option in the Edit Donor Name dialog box (not shown) to
retain the current donor name; whereby, the Donor Entry/Edit dialog
box 221 would reappear, showing the unchanged name. Note that a
changed name is not saved in the donor record until the operator
clicks the Apply or OK button 229 or 230 in the Donor Entry/Edit
dialog box 221.
[0116] Similarly, at any time while using the Donor Entry/Edit
dialog box 221, the operator may change the donor's ID, while
retaining the current donor name. To do so, the operator would
click the Edit Donor ID button 225 (see FIG. 2B) in the Donor
Entry/Edit dialog box 221. An Edit Donor ID dialog box (not shown)
would preferably be made to appear, displaying the current donor
ID. The operator could then enter a new ID for the donor in the New
Donor ID box, and click an OK button (not shown) to save the ID
change. The Donor Entry/Edit dialog box 221 reappears, showing the
changed ID. The operator can also decide not to change the donor's
ID, and click a Cancel option in the Edit Donor ID dialog box (not
shown) to retain the current donor ID; in this case, the Donor
Entry/Edit dialog box 221 would again reappear, showing the
unchanged ID. Note that a changed ID is not saved in the donor
record until the operator clicks the Apply or OK button 229 or 230
in the Donor Entry/Edit dialog box 221.
[0117] At any time, the operator can search for and select the
record for any donor who is already checked in to the system.
However, if the donor is already checked in to the system, the
following fields, inter alia, in the Donor Entry/Edit dialog box
221 may be preferably disabled and therefore cannot be modified:
General tab: Gender; History tab: Blood Type; Status tab: Donor
Status.
[0118] Once the appropriate/desired donor data is satisfactorily
entered, edited and/or verified using screen 221 (FIGS. 2B-2I), the
donor may then be checked-in to the next step in the process, the
Prepare Procedure step/sub-procedure (described below). Donor
check-in may be accomplished from any view of screen 221 by
clicking the "OK" button 230 (or another appropriately labeled
button, e.g., "Check-in" if so provided, not shown). This may then
send the donor information to the Prepare Procedure portion of the
software application (e.g., to the Prepare Procedure software
module, if the software is so modulized as is preferred).
Alternatively, a pop-up dialog box (not shown) can be made to
appear for confirmation that donor check-in is desired. "Yes" or
"No" options may be provided in such a pop-up dialog box to confirm
the operator's desires. Clicking the "Yes" option will then pass
the donor information to the Prepare Procedure Step, as described.
Note, clicking the "No" option will provide for not passing the
donor information to the next procedural step; however, it may be
made to either save all edited/entered information while exiting
the Donor Entry/Edit screen 221, or it may be made to call up a
further pop-up window to confirm whether the edited/entered
information should be saved to the central memory 142 before
exiting the Donor Entry/Edit screen 221. Note also that, as will be
described below, the donor data entered/edited via screen 221 may
be made further enterable/editable at later stages of the overall
procedure after initial check-in, still preferably through use of a
screen 221, or the like. Thus, provision (preferably through
clicking the Select Donor icon 207 in bar 205; see FIG. 2A) may be
made to return to screen 221 or the like at later stages of the
procedure to enter new data or modify existing data, as may be
desired. However, at such later stages, a check-in option would not
preferably be made available if (as would be true in such a
situation) the donor had/has already been checked-in. Thus,
clicking the "OK" button 230 (see FIG. 2B, e.g.) would only save
the information to the donor record in memory 142 and not proceed
to a "Check-in" dialog box, if used (not shown).
[0119] FIG. 3A shows the next step in the overall general component
collection procedure, which would appear after donor check-in is
completed as described above. This next step corresponds generally
with the shown display screen 301 which would have been accessed
via clicking on the Prepare Procedure icon 208 in the procedure
icon area 205. This next step in the data entry/manipulation
process shows, via the display screen 301, the donors who have been
checked into the system and are now ready for selections of the
desired collection procedures to be performed. The work area 202 of
screen 301 in FIG. 3A then preferably displays a listing of donors
(via a text list (not shown) or by representative icons as shown,
or otherwise (not shown)), which have been checked-in according to
the above-described procedures(s). This grouping or listing of
checked-in donors may also be referred to as a "donor queue." A
donor may then be selected from this queue by clicking the
corresponding icon 302 or 303, for example. Once the donor is
selected in screen 301 (selection being indicated by distinctive
shading, see icon 303 in FIG. 3A), the next step can be accessed by
clicking the "Prepare" button 304 in the main work area 202, or, in
an optional embodiment, by again clicking the "Prepare Procedure"
icon 208 in the icon area 205. Note, a "Remove" button 305 could
alternatively be selected to remove the donor from the Checked-in
Donor Queue, (i.e., from the work area 202) if desired. Also, help
may be obtained at any time by selection of the "Help" button 306.
Note, in a preferred embodiment, the donor icon(s) 302 and/or 303
may include the donor's photo (i.e., as introduced above, the
computer/database system 140 may also be equipped with a digital
camera as is known in the art of computer systems generally).
[0120] There may be at least two general and perhaps overlapping
preferences for separating the Donor Check-in functionality from
the Prepare Procedure functionality. Specifically, a first such
preference may derive from the three room scenario
suggested/described above, wherein a donor may be greeted by a
receptionist or receptionist-type of operator in a "Reception" room
or area. Then, the donor information described generally above (see
FIGS. 2A-2I, e.g.) may be entered and/or edited and/or verified at
such a "Reception" point of the overall procedure. The donor may
then be moved to a second, discrete room where a second, discrete
operator may perform the Procedure Preparation steps described
hereinbelow. These rooms/areas may be separate physically or rather
may not actually be separate at all, depending upon the blood
center and its preferred operating procedures and facility
arrangements. The operators may also not be discrete; however, the
second, likely overlapping preference for the functionality
separation may be that there are two separate operators and the
second operator may have different technical skills and/or
qualifications from the first operator, i.e., the second operator
may be qualified to run the actual collection procedure while the
first, reception operator/person may not. Thus, by separating these
functionalities (even if the "rooms" are not separated), the
reception person or the reception area computer may be given access
limited only to the Select Donor icon functionality, for example.
At the same time, the perhaps higher qualified collection operator
may be relieved of the data entry/edit tasks associated with
initial check-in procedures.
[0121] As a result of finishing the previous steps (data entry
modification and donor check-in), the Prepare Procedure portion of
the overall process may be performed next. As shown in FIG. 3B, a
"Prepare Procedure" sub-procedure, preferably a "Prepare Procedure"
Wizard, as depicted by a first Wizard display screen 321, may
substantially automatically lead the operator through the procedure
preparation process. Note, a wizard as known in the art generally,
may be a software module or sub-procedure which includes a series
of screens used to accomplish a particular task or operation. Note,
this "Prepare Procedure" wizard screen and/or other such screens
(as follow) may be sub-windows or full window-sized displays.
[0122] In particular, as shown here, respective screens 321, 331,
341, and 351 of respective FIGS. 3B, 3C, 3D, and 3E represent
substantially sequential wizard screens accessed initially by the
selection of the "Prepare" button 304 (after selection/highlighting
a particular donor icon, e.g. icon 303) of screen 321 in FIG. 3A.
These wizard screens 321-351 are then sequentially accessed; one to
the next, by the selection of the respective "Next" buttons 322
(see lower portions of screens in FIGS. 3B and 3C, e.g.).
Backtracking, in reverse order, of these wizard screens is also
available by selection of the respective "Back" buttons 323,
disposed preferably adjacent the "Next" buttons 322. Other general
wizard buttons such as the "Help" button(s) 324, the "History"
button(s) 325 and the "Cancel" button(s) 326 may be selected at any
general point in this process to obtain respectively
assistance/information, a history of data entry/edits (and/or
optionally displayed screen views 321-351, e.g.) and/or to cancel
the Prepare Procedure wizard at any time.
[0123] Further details of preferred process for using these
preferred and like screens will now be set forth.
[0124] The operator is presented with the first page of the
"Prepare Procedure" module/wizard/sub-procedure, the Donor
Identification page 321 as shown in FIG. 3B. This page shows the
donor's name, donor ID, date of birth (DOB), and photo (if
previously taken and/or saved in the database 142). This page
allows the operator to confirm the donor's identity and,
optionally, to take or update a photo of the donor. An "update
picture" button 328 may be supplied for providing a new or updated
photo. Field specific behavior of these items is preferably as
follows: the "Donor Name is pre-populated with first and last name
from the donor record data, and is preferably not editable here.
The "Donor ID" is also pre-populated, and preferably not editable.
The "Date of Birth" field is pre-populated using localized format,
and not editable. And, the "Donor's photo" is also preferably
pre-populated to further assist the operator confirm the proper
donor is present for this procedure being prepared. If such a photo
is not available for this particular donor, a generic male or
female icon may be displayed. The operator may then click the
"Next" button 322 to proceed to the next page of the wizard.
[0125] A Unit Number text box 329 may also be disposed in either of
screens 321 or 331 (or elsewhere, see FIG. 3B). A Unit Number is
preferably a required field entry. The operator may enter the unit
number either by typing the number in the Unit Number box 329, or
by using a barcode reader (not shown, e.g., by highlighting the
unit number field 329 and then using the bar code reader to scan
the supply bar code which would then populated this field 329). The
unit number may be supplies related information or taken therefrom
as related to the tubing set type used, or the bag identifiers to
be used. The Directed Donor and HLA matched boxes 330 are further
alternative fields which could be entered/edited at this (or a
later) stage of the procedure. These fields are directed to noting
whether this donor is providing a donation for a specific
pre-identified recipient, and the HLA match box merely records
whether the HLA types have already been matched for such a directed
donation per pre-existing techniques. The operator may then click
the Next button 322 to proceed to the next page, or the Back button
323 to return to the previous page.
[0126] Then, as shown by the display screen 331 in FIG. 3C, gender,
height, weight, hematocrit and platelet pre-count parameters will
preferably be entered, if not already populated in the respective
fields 332, 333, 336 and 337 as previously entered in and thus
disposed in the database 142. In fact, even if these parameters are
previously entered, these fields in this screen 331 may be made
mandatorily re-entered here, or at least re-confirmed before the
system 140 may allow the operator or donation process to proceed
(note, if re-entered here, it may be that this data re-entry could
rewrite the database information at this point or at the end of the
collection process as part of the entire record which is saved to
the central database 142 at that time). The other fields shown in
this FIG. 3C are preferably entered as well, but may be made
optional. As introduced above, and as will be understood from
further description below, the required fields may be populated
with historical data until the current lab values come back.
[0127] More particularly, the operator is presented with the Donor
Information page 331 of the wizard, see FIG. 3C. Donor "vitals" are
taken and entered on this page. The following items are preferably
displayed on the Donor Information page 331. The Donor's Gender is
preferably pre-populated in field 332, required, and editable via
selection: Male or Female. The Donor's Height and Weight are
preferably also pre-populated (see fields 333) with the last value
(from database 142, if available) in localized units, editable, and
required. The value written to the database will indicate if the
value was changed. The "TBV" (Total blood volume) in field 334 is
dynamically calculated (non-editable), based on the Height, Weight,
and Gender fields 332, 333. The Donor Blood type is also preferably
pre-populated in field 335, either from database 142 or (if unknown
for this donor) pre-populated with Unknown. This field is
preferably editable via a selection: O+, O-, A+, A-, B+, B-, AB+,
AB-, or Unknown.
[0128] The Hematocrit/Hemoglobin field 336 is labeled either
Hematocrit as shown or Hemoglobin (not shown), based on the system
setup that is defined by the System Administrator. Data in this
field is required, and may be entered by the operator, or a default
value may exist. If the Administrator configures this field to use
a default value, and historical data of the configured type is
available for this donor, the field is pre-populated with the
historical data. The type of historical data used as the default
may be configured by the Administrator to be one of the following
types: Average of last three pre-procedure values; Last visit's
pre-procedure value; No default value; Gender-based default value;
or blood center chosen default value. The value written to the
database and displayed on the page indicates if the value is one of
the configurable defaults above or if it is a measured value
entered by the operator.
[0129] The Platelet Pre-count field 337 is also entered here. Data
in this field 337 is required, and may be entered by the operator,
or a default value may exist preferably as defined by the
Administrator. If the Administrator configures this field to use a
default value, and historical data of the configured type is
available for this donor, the field is pre-populated with the
historical data. The type of historical data which may be used as
the default may be configured by the Administrator to be one of the
following types: Average of last three pre-procedure values; Last
visit's pre-procedure value; No default value; Gender or
Center-wide default. The value written to the database and
displayed on the page preferably indicates if the value is one of
the configurable defaults above or if it is a measured value
entered by the operator.
[0130] In addition to the above, preferably required items, the
operator may enter the appropriate optional donor vitals (see
generally fields 338); Temperature (an optional field in localized
units: Fahrenheit or Centigrade); Blood pressure; and Pulse
(optional fields).
[0131] When all required information (and any optional information
the operator chooses to enter) has been entered, the operator
clicks the Next button 322 to proceed to the next page 341 or 351
(FIG. 3D or 3E), or the Back button 323 to return to the previous
page 321 (FIG. 3B). Note, if a required field does not have an
entered value, an attempted click of the Next button 322 will
preferably present a prompt that a value must be entered in this
field before the wizard can proceed to the next page. Note, if the
operator enters a value in a field that is above or below the
allowable limits for that field (hard limits), or a value that is
unusually high or unusually low (soft limits), a message will
preferably be made to appear. If this is a soft limit, the message
informs the operator that the value is outside the limits and asks
if the operator wishes to proceed. The operator may click a Yes
option to use the value and proceed, or No to enter a new value. If
this is a hard limit, the operator may be required to enter a new
value in order to proceed. Also, if the blood center uses a blood
bank information system, a warning message will preferably be made
to appear when the operator changes a donor demographic field on
the Donor Information page 331 (FIG. 3C). This warning would
indicate that the demographics data must be changed in the blood
bank information system to be permanently saved.
[0132] In a simplified process (usually for operators with lower
qualifications, or wanting or needing fewer choices), after the
operator has clicked the "Next" button 322 (FIG. 3C), the operator
is then presented with the Target Procedure page 351 (FIG. 3E) of
the wizard. Screen 341 (FIG. 3D) is skipped in this simplified
procedure. The operator may then accept the recommended target
procedure (shown highlighted with a rightward-pointing arrow icon
355 in FIG. 3E). Note that the target procedure is obtained by the
system 140 running the apheresis time and/or product yield
optimization routines such as are run on the Trima collection
systems 10 (and as described below, see description accompanying
FIGS. 7-10) in the present system application, and that the
parameters for the highlighted procedure are preferably shown above
the procedure list. The operator may then optionally click the
Finish button 352 (FIG. 3E) to complete the "Prepare Procedure"
apheresis procedure selection process.
[0133] Note, the running of the apheresis optimization routines by
system 140 preferably involves the use of data either from storage
in the central memory 142 and/or as input into system 140 via input
devices 149 at any station 148 (as described hereinabove)
preferably through use of the sub-procedures described herein
(i.e., using the screens shown in FIGS. 2A-2I and 3A-3C) and
communicated through subsystem(s) 146 and then manipulated by the
manipulation device 144. The manipulated data may then result in
optimized data which can then be interpreted by the system as
representing a system preferred target procedure (or procedures)
such as is shown in FIG. 3E. Again, optimized data would provide
usually either the largest yield in a certain time, or the shortest
time to reach a minimum yield (see FIGS. 7-10, below). Other
manipulations may provide for procedures which may not be either
time or yield optimized, but which a blood center may find
otherwise perhaps more desirable, such as platelet (or other
component) preferences no matter what the optimization program(s)
might suggest. Thus, the system 140 and manipulation device 144 can
manipulate the donor statistics (vitals, etc.) against a large
plurality of procedure types and compare with blood center
prioritizations to obtain various sorts of procedure lists such as
that shown in FIG. 3E. Preferably, the optimal procedure (optimized
or merely manipulated according to system administrator
pre-selections) may be returned with the rightward-pointing icon
355; however, preferably also other procedures will be listed also
with various icon representations to signify prioritization. For
example, as shown in FIG. 3E, numerous procedures are shown with a
circle with a diagonal line which here preferably represents
procedures which are not available due to physical (and/or safety)
constraints such as the donor not meeting a minimum hematocrit or
total blood volume preferred therefor. Green circles, inter alia,
can be used to signify less than optimal procedures, which would
nevertheless be available for this donor to be subjected to.
Question marks could be used to signify procedures, which could be
available options if the parameters (e.g., time, lab values, etc.)
were to change (i.e., if more time were allowed for a
collection).
[0134] Note several alternative actions may be presented. For
example, in some instances it may occur that more than one target
procedure may be indicated, whereby the operator may then choose
the preferred procedure. Or perhaps the donor may be disqualified
such that no procedures appear available. The donor can be
disqualified for the donation based on the donor vitals or
screening questions. In this situation, the operator may press the
Cancel button 326 on any page in the Prepare Procedure Wizard to
discontinue the prepare procedure process. The operator may then
remove the donor from the Checked-in Donor Queue, as described in
the "Prepare Procedure" sub-procedure above.
[0135] Otherwise, the donor may be unable to donate if the central
system 140 cannot determine a valid apheresis procedure to run for
this donor. If this is the case, the central system 140 preferably
displays a dialog box (not shown) explaining the reason a procedure
cannot be determined. Based on the blood center's policy, the
operator may ask the donor if the donor can stay longer. The
operator may then extend the procedure time, as described in the
"Adjust Donation Time" alternative sub-procedure below.
[0136] As noted, the operator may adjust the donation time. If the
donor can only stay longer or perhaps only a certain limited amount
of time, the operator may change the default maximum procedure time
by clicking the Adjust button 353 (FIG. 3E). The operator is
presented with the Procedure Adjustments dialog box 361 (see FIG.
3F), in which the operator may enter a new maximum procedure time.
The operator may then click the OK button to return to the Target
Procedure page 351 (FIG. 3E) of the wizard. If the maximum
procedure time is changed, the Target Procedure page is
re-optimized and possibly recommends a different procedure. It is
also possible that there are no procedures available as a result of
the time change.
[0137] Similarly, the operator may adjust the tubing set type
availability. If only certain tubing sets are available, the
operator may change the tubing set type availability by clicking
the Adjust button 353. The operator again is presented with the
Procedure Adjustments dialog box 361, in which all three tubing set
types (e.g. Grey, White, and Black options for the Trima apheresis
systems 10; other optional set types and/or designations may be
used for other blood processing systems 10, as desired) are checked
by default. The operator may uncheck one or more tubing set types.
The operator may then click the OK button to return to the Target
Procedure page 351 of the wizard. If the tubing set type
availability is changed, the Target Procedure page is re-optimized
and possibly recommends a different procedure. It is also possible
that there are no procedures available as a result of the tubing
set availability change.
[0138] Note, the operator may also select certain different
procedures in the procedure list shown in screen 351 (FIG. 3E). The
operator may select a procedure with an icon indicating that the
procedure can be run for this donor (though perhaps not the optimal
procedure according to the system 140), or a procedure with an icon
indicating that the procedure can be run for this donor, but only
if the donor's actual hematocrit and/or platelet pre-count change
significantly from the values entered in screen 331 (or the default
values used in screen 331). In any event, preferably the operator
cannot select a procedure with an icon indicating that the
procedure cannot be run for this donor. Note that when the operator
selects a different procedure in the list, the parameters for the
selected procedure are shown above the procedure list. Note, the
operator may also view any of the listed procedure details. To do
so, the operator may double-click a listed procedure to view a
Procedure Details dialog box (not shown), which may provide more
detailed information about the procedure. The operator may
double-click either the currently selected procedure, or any other
procedure in the list. The operator may click an OK button to close
the Procedure Details dialog box (not shown) and return to the
Target Procedure page 351 of the wizard. If the operator
double-clicked a procedure other than the currently selected
procedure, the procedure that the operator double-clicked would now
preferably be selected (e.g., highlighted) in the Target Procedure
page 351.
[0139] Note also that an operator may select different donation
options, preferably after the step depicted by screen 331 (FIG.
3C), but prior to the step depicted by screen 351 (FIG. 3E).
Preferably, however, this option would be limited to higher
security users preparing the donation. Then an additional page 341
(FIG. 3D) would appear, allowing finer control of the donation.
This page 341 would be presented only to individuals with the
higher privilege level. The following two steps could be added for
this operator. The operator would choose the blood product types
eligible for this donation (e.g. platelets, RBC's or plasma). These
choices would be used to disqualify one or more product types from
being collected. By default, all product types are preferably
eligible for a donation. Thus, a check in the corresponding box in
area 342 of the "Select Products and Configuration" page 341 would
indicate that the product type may be collected. If the
corresponding box is unchecked, any procedure that would collect
this product type is disqualified in the Target Procedure page 351
(FIG. 3E). The three choices are platelets, plasma and red blood
cells. Any combination hereof may be checked. As shown in area 343,
the operator may also select alternative apheresis system
configurations or product focus lists to utilize for this donor's
donation. Note that these changes would preferably only apply to
this donation. For Focus Lists, the operator may select a product
focus list from this drop-down list. The center-wide default focus
list is preferably pre-populated in this drop-down list. All focus
lists that have been defined by the Administrator will then appear
in this drop-down list. For Machine Configuration, the operator may
select an apheresis system machine configuration from this
drop-down list. The center-wide default machine configuration is
preferably pre-populated in this drop-down list. All machine
configurations that have been defined by the Administrator will
then appear in this drop-down list.
[0140] At any point while using the Prepare Procedure Wizard, the
operator may click the History button 329 (see FIG. 3C) to view the
donor's record. When the operator clicks the History button 325,
the Donor Entry/Edit dialog box 221 (see FIGS. 2B-2I) appears,
showing all information in the donor record. To return to the
Prepare Procedure Wizard, the operator clicks the OK button in the
Donor Entry/Edit dialog box 221.
[0141] Note, the sub-procedure depicted by the screens in FIGS.
3B-3E may be known generally as "screening" in suggesting that
these functions may be performed in the second room, the
"Screening" room, of the three room model described above.
[0142] Then, in the next procedural step as shown by the display
screen 401 in FIG. 4A, the donor may be assigned to a blood
processing machine 10. Screen 401 may be accessed via a button such
as the "Finish" button 352 appearing on the last page 351 (FIG. 3E)
of the "Prepare Procedure" wizard/sub-procedure, or more preferably
by clicking the "assign machine" icon 209 appearing in the icon
work area 205 (see FIGS. 2A and 4A, e.g.). Assigning a donor to a
machine may be a simple matter of clicking and dragging the donor's
icon 402 (with or without photo) to an available Trima or like
apheresis machine icon 404 as shown in the respective left and
right portions 406, 408 of the main work area 202 in screen
401.
[0143] Note however, that any particular donor will preferably not
be available (i.e., no icon will preferably show up) in the icon
list 406 (also labeled as a "Donor Assignment Queue") until
completion of the "Prepare Procedure" sub-procedure (i.e., as
accessed using the "Prepare Procedure" icon 208, e.g.) as described
for the wizard module in FIGS. 3B-3F. However, after the "Prepare
Procedure" sub-procedure is completed, preferably after the
clicking of the "Finish" button 352 on the last screen 351 of the
wizard (see FIG. 3E), a donor icon for that donor, such as icon
402, e.g. is preferably automatically generated and automatically
placed in the icon list 406. Thus, the donor, as represented by the
icon, is then ready to be assigned to a particular apheresis
assembly 10.
[0144] In more detail, to do so, the operator will first preferably
double-click the Assign Machine task icon 209 in the main window
task bar 205, or, alternatively, the operator may select the Assign
Machine element (not shown) from the Tasks menu 216. The Assign
Machine task window 401 is then displayed, showing two panes: the
Donor Assignment Queue 406 and the Machines list 408. The Donor
Assignment Queue 406 shows donor icons (e.g., icon 402) for all
donors who are ready for machine assignment. Donor icons are
preferably ordered in the queue based on the time an operator
finished using the Prepare Procedure Wizard (see above) to prepare
a procedure for the donor. The donor for whom the Prepare Procedure
Wizard was finished the longest ago preferably appears at the top
of the queue. The donor for whom the Prepare Procedure Wizard was
finished most recently preferably appears at the bottom of the
queue. The Machines list 408 shows an icon for each apheresis
system in the facility that is enabled in the current network. To
help the operator make a decision about which machine to select for
a donor, the following information is preferably displayed as part
of each machine icon: run status; time remaining if a procedure is
currently running on the machine; name of the next donor queued for
the machine; machine communications status (online or offline).
[0145] To assign a donor to a machine, the operator preferably
selects a donor icon from the Donor Assignment Queue 406 and drags
it to a machine icon in the Machines list 408. Alternatively, the
operator may select a donor icon 402, e.g., (by
highlighting/clicking it once, not shown) and a machine icon 404
and then click the Assign button 410 to make the assignment. A
confirmation dialog box (not shown) may then be displayed with
"Yes" and "No" options to ask the operator to confirm the
assignment. If the operator clicks the "Yes," option, the system
may then close the confirmation dialog box, and, in the Assign
Machine task window 401, the following preferably occurs: the donor
icon 402 is removed from Donor Assignment Queue 406 and the machine
information in the Machines list 408 is updated to show that the
donor is assigned to the machine. If the operator clicks the option
"No," option, the system closes the confirmation dialog box, and,
in the Assign Machine task window 401, the following occurs: the
donor icon 402 remains in the Donor Assignment Queue 406, and the
machine information in the Machines list 408 is unchanged. After a
short delay, the donor information (and photo, if available)
appears on the apheresis system. In addition, the donation-specific
apheresis system configuration is in effect on the machine. At this
point, the operator may continue using the Assign Machine task
window or select another option in the system main window.
[0146] Some alternative process flows for donor/machine assignments
are as follows.
[0147] It may be possible that all machines 10 are non-functional.
If this is the case, the operator (or another member of the
facility's staff) will need to fix the problem at those machines
10, to make at least one machine 10 available. If this is not
possible, the operator may be required to remove all donors from
the Donor Assignment Queue, as described below.
[0148] At any time prior to machine assignment, the operator may
edit the information about a procedure by selecting the donor's
icon (e.g., icon 402) in the Donor Assignment Queue 406 in screen
401 and clicking the Edit button 405. The Prepare Procedure Wizard
(see FIGS. 3B-3E) appears, allowing the operator to edit the
procedure information. Once the operator clicks Finish 352 on the
last page 351 of the wizard, the Assign Machine task window 401 is
redisplayed. (Alternatively, the operator may redisplay the Assign
Machine task window 401 by clicking Cancel 326 on any page of the
wizard; however, in this case, the modifications that were made in
the wizard are discarded.)
[0149] At any time prior to machine assignment, the operator may
remove a donor from the Donor Assignment Queue 406 by selecting the
donor's icon (e.g., icon 402) in the Donor Assignment Queue 406 and
clicking the Remove button 407. A Confirm Remove Donor dialog box
(not shown) may be made to appear, allowing the operator to enter a
reason for the removal and/or select a reason from a predefined
list (preferably created by the Administrator). Once the operator
clicks the OK option in the Confirm Remove Donor dialog box (not
shown), the donor's icon is removed from the Donor Assignment Queue
406.
[0150] The operator may also unassign a donor from an apheresis
system 10 under the following conditions; namely, if another donor
is currently donating on the machine, and the donor the operator
wants to unassign is queued to donate on the machine, and/or if the
machine is offline. To unassign the donor, the operator may click
the machine icon 404 in the Machines list 408 and then click the
Unassign button 412. The machine icon 404 returns to its previous
state. In addition, an icon (e.g., icon 402) for the unassigned
donor reappears in the Donor Assignment Queue 406. To distinguish
this donor from donors who have not yet been assigned to any
apheresis system 10, this donor's icon is gray. The donor may then
be reassigned to an apheresis system 10 as described in the basic
procedural flow, or removed from the Donor Assignment Queue 406 as
described in the "Remove Donor" alternative flow, above. Note: the
Unassign button 412 is disabled when no machine icon is selected.
If the operator then clicks a machine icon (such as icon 402, inter
alia) the Unassign button 412 will remain disabled, the unassign
feature not being available for that machine at this time.
[0151] If a donor is assigned to an apheresis system 10, but then
is dismissed at the apheresis machine 10 using, for example, the
touch-screen display 199, the machine icon 402 in the Machines list
408 in the Assign Machine task window 401 returns to the "Ready for
Donor" state. In addition, an icon (e.g., icon 402) for the
dismissed donor reappears in the Donor Assignment Queue. To
distinguish this donor from donors who have not yet been assigned
to any apheresis system 10, this donor's icon is "grayed-out". The
donor may then be reassigned to an apheresis system 10 as described
in the general sub-procedure for Assign a Donor, or removed from
the Donor Assignment Queue 406 as described in the "Remove Donor"
alternative sub-procedure, above.
[0152] After assigning a donor to an apheresis machine 10 as
described, the display screen 421 shown in FIG. 4B appears on the
corresponding display area (e.g., touchscreen 199, if used) of the
assigned blood component apheresis assembly 10 itself. The operator
may then either confirm the information appearing on the apheresis
screen 421 by depressing the "continue" button 422, or the like; or
the operator may touch/push the box 423 marked with an "X" to
decline the donor assignment, thus sending the donor data back to
the central system 140 and figuratively send the donor back to the
"waiting/screening" room. The apheresis screen 421 shown here may
have touch-screen capabilities as understood in the art, or may
accept input through other means such as mouse driven cursors,
inter alia, which are within the skill of the art.
[0153] Note, it is still also conceived that though perhaps not
preferable, there may be situations in which the system may be
configured to allow the operator to enter data directly on the
apheresis machine 10 itself and then perform data manipulation
and/or optimization as is known for many existing machines 10
without requiring the use of a central computer/database system
140. Nevertheless, it is also conceivable that in such a situation
it may be preferable to still collect data at a centralized system
140 for database or reporting purposes.
[0154] After the download of the information from the
computer/database system 140 to the actual apheresis machine
assembly 10 as described, then the computer/database system 140 may
preferably only be used for monitoring and/or reporting. This
follows a preference that all actual apheresis control during a
procedure remains resident in the apheresis machine 10, itself. It
is possible, however, if not preferable, to have computer/database
system 140 exert control over apheresis machine functions,
including process control manipulation and optimization, during
procedures, as well. In either case, as shown in screen 501 of FIG.
5A, it is at this point that the computer/database system 140 can
be used to monitor the procedure(s) occurring on one or more
apheresis machines 10. All procedure interventions again would
preferably occur directly on the apheresis machine 10 through its
touch screen 199 or other input mechanism as known in the art.
[0155] In monitoring mode, real time monitoring of procedures on
the centralized computer/database system 140 allows the
administrator to know the status of collection of any or all
machines 10 at a glance. This can help with scheduling and
management. Alarm states may also be displayed and/or all other
occurrences and/or activities of each machine may be recorded (not
specifically shown). As shown in screen 521, FIG. 5B, detailed data
information can be called up to assess the status of a procedure.
More details concerning these display screens and the information
thereof will now be set forth.
[0156] In operation the operator preferably double-clicks the
Monitor Procedure task icon 210 in the main window task bar 205
(FIGS. 2A and 5A), or, alternatively, the operator may select the
"Monitor Procedure" element (not shown) from the Tasks menu
216.
[0157] The present system 140 preferably provides users with the
ability to view the status of all procedures currently running on
machines 10 connected on the local machine network 146A (see FIG.
1C), as well as procedures which have completed on a machine 10,
but for which not all required finalization data has been added to
the procedure record. Status information is supplied continuously
from each machine 10 to visit status table (not shown) in the
central database 142. The Monitor Procedure module scans an
internal visit status table recurrently; the Monitor Procedure task
window 501 is preferably updated based on the current data in the
internal visit status table. Using the Monitor Procedure function,
operators can enter a comment about a procedure; enter finalization
data about the procedure, such as supplies data and operator roles;
view more detailed information about a procedure's status; or force
record completion, inter alia.
[0158] The basic flow for the monitoring sub-procedure is as
follows. Two different general types of procedures are displayed in
the Monitor Procedure task window 501; namely Active and Pending
procedures. In Active procedures, all of the procedures currently
running on machines 10 connected to the machine network 146A,
including active procedures currently in an alarm state, are shown.
Pending procedures are procedures that have been completed on the
apheresis machine 10, but for which not all required finalization
data may have been entered in the procedure record. Note,
procedures are considered active from the time that donor and
procedure data is downloaded from central system 140 to an
apheresis machine 10, until the time that the central system 140
receives indication from the apheresis machine 10 that either the
procedure run has been completed, or the operator has indicated on
the apheresis machine 10 that the procedure run is incomplete.
[0159] In the Monitor Procedure task window 501, procedures are
preferably displayed in table format (as shown in FIG. 5A). For
each procedure, the following information is preferably displayed:
machine ID; collection stage and status; donor name; procedure
name; and the time remaining. In addition, an icon (e.g., icon 503)
next to each procedure description may preferably indicate if the
procedure is in an active, pending, or even an alarm state.
[0160] The operator may then optionally select a procedure in the
list and then click the Add Comment button 505 to enter a comment
in the procedure record for that procedure. An Enter Procedure
Comment dialog box (not shown), may then be made to appear. The
operator can then select a comment from the pre-configured comment
list (preferably created by the System Administrator) and/or enter
a free-form text comment entry.
[0161] The operator may then optionally select a procedure in the
list and then click the Procedure Information button 507 to enter
data about the procedure, such as supplies data and operator roles.
A "Finalize Procedure Information" dialog box may then appear,
showing the Supplies tab. (For more information about this dialog
box (not shown), see the "Finalize Procedure" descriptions (FIGS.
6C-6I, below).
[0162] The operator may also optionally select a procedure in the
list and then click the Status button 509 to view more detailed
information about the procedure. A Procedure Status dialog box 521
(see FIG. 5B) may then appear. (Optionally, the operator may
double-click the selected procedure in the list to view this
Procedure Status dialog box 521.) This dialog box 521 preferably
shows the procedure time (time remaining, total time, and estimated
end time) and the current collection status for each of the three
blood product types (platelets, plasma, and RBCs), which may be in
the process of being collected as part of a procedure.
[0163] Several alternative conditions and/or sub-procedures may be
available in Procedure monitoring. For example, when an alarm,
warning or alert condition occurs within an active separation and
collection procedure, the system may change the icon next to the
procedure description in the Monitor Procedure task window 501 to
an "alarm" icon (not shown). The operator can view the alarm
description (preferably uploaded automatically to central system
140 from the apheresis system 10 generated by the run data for the
procedure) by selecting the procedure from the procedure list in
the Monitor Procedure task window 501 procedures list 504, clicking
the Procedure Information button 507, and then clicking a Procedure
Log tab in the Finalize Procedure Information dialog box (see
similar description in FIGS. 6C-6I, below). However, the alarm
cannot be resolved in the preferred embodiment directly within the
central system 140. The alarm must then be resolved at the machine
10. Once this alarm (and any other alarms on the machine) have been
resolved at the machine 10, the central system 140 may change the
icon next to the corresponding procedure description back to an
"active procedure" icon such as icon 502, for example, as opposed
to an inactive icon 503.
[0164] At any time, a procedure may no longer meet the active or
pending criteria. An update to the visit status table in the
central database 142 may cause a procedure that was previously
displayed in the Monitor Procedure list on screen 501 of procedures
to be removed from the list. Only procedures that have a status of
active or pending are preferably displayed in the procedure list.
If a procedure previously was active or pending, but no longer
meets that criteria the next time central system 140 scans the
visit status table, the procedure is no longer displayed in the
Monitor Procedure task window 501.
[0165] At any point in monitoring procedures using screen 501, an
operator may sort procedures in procedure list. In particular, the
operator may click one of the column headings in the procedure list
to sort the procedures using different criteria. Procedures may
preferably be sorted by one of the following: Machine ID, Status,
Donor Name (first name, last name), Procedure, or Time Remaining.
The first time the column heading is clicked, the procedures are
sorted in ascending alphanumeric order. Each subsequent click of
the column heading results in a display of the elements in the
opposite alphanumeric order (ascending or descending).
[0166] As a usual last step in the overall blood component
separation and collection process using a central system 140, the
record finalization and reporting function of the computer/database
system 140 will now be briefly introduced. First, the
computer/database system 140 is preferably capable of capturing a
great deal of optional information from the apheresis system 10 as
well as from manual entry. This end-of-run information may then be
used in generating a multitude of optional reports in addition to
standard run records, both of which optionally being formattable as
desired by the operator (see FIGS. 6K, 6L and 6M, described below).
Further, various types of data can be sorted and measured relative
to each other as desired as well. For example, the time period of
the entire collection procedure can be reported relative to the
numbers and/or quantities of the products collected (volumes or
contents). Or, certain quality measures may be reported against
either or any of the other data collected by the computer/database
system 140. In addition, certain data may be manipulated, edited or
amended, or comments added thereto after a collection procedure.
For example, certain additional information may be added such as
information about the type of tubing set used or post procedure
laboratory values. Nevertheless, the data generated by the
apheresis machine 10, itself, very preferably would not be capable
of being edited or changed in any way. As above, more details of
the overall reporting functionalities will now be set forth.
[0167] The present invention allows operators to search for and
select any procedure record in the central database 142, whether
the procedure record is opened (as for active and pending
procedures) or closed (as for finalized procedures). As shown, for
example by screen 601 in FIG. 6A, operators can search for
procedure records based on donor ID, unit number, or a range of
dates. Once the desired procedure record has been found, the
operator can access the procedure record to do one of the
following: View and/or enter finalization data (see the "Finalize
Procedure Record" sub-procedure described below); or, View and/or
enter lab results data (see the "Lab Results Entry/Edit"
description below; FIG. 6J)
[0168] The Basic Flow of this sub-procedure case follows the
scenario that the operator preferably searches by either donor ID
or unit number, and that the operator wants to view/enter
finalization data for the procedure. The operator preferably
double-clicks the Select Procedure task icon 211 in the main task
bar 205 (FIGS. 2A and 6A), or, alternatively, the operator may
select the "Select Procedure" element (not shown) from the Tasks
menu 216 (FIG. 2A). The operator may then search the central
procedure record database 142 for the desired procedure records,
either by donor ID (see field 602) or unit number (field 603).
Searching by a range of dates (see fields 604) is another preferred
alternative. The operator clicks the desired radio button, which
clears any information that may be currently shown in other
selection option fields, and the operator then enters a full or
partial entry of the donor ID or unit number or dates in the
appropriate box. Logical and/or boolean-type searches are also
preferably available. Alternatively, the operator may use the bar
code reader (not shown) to enter the donor ID or unit number. For
date searching, the operator may enter a starting date in the From
box, and enter an ending date in the To box. Either date can be
typed in the text box or selected using a pop-up calendar (see
calendar 611 in FIG. 6B).
[0169] The operator may then click the Search button 610 or press
the Enter key (on the keyboard, if used). The central system 140
then searches the central database 142 and displays all possible
matching procedure records in the Search Results box 612. The
search finds both open and closed procedure records. In date
searching, the Search Results box displays all procedures that were
performed within the specified date range.
[0170] The operator may then click the desired procedure record in
the Search Results box 612, and then click the Procedure
Information button 614 (shown grayed-out in FIGS. 6A and 6B, since
a record is not yet selected there, i.e., is not yet highlighted. A
Finalize Procedure Information dialog box 621, which may also be
known as a Procedure Data Entry Edit box 621 (see FIGS. 6C-6I) then
appears (optional double-clicking of the procedure entry in the
Search Results box 612 may also display the Finalize Procedure
Information dialog box 621), here showing a Supplies tab 631. (For
more information about this dialog box, see the "Finalize
Procedure" sub-procedure described below.)
[0171] Note: alternative search steps may also be performed. For
example, if the operator clicks the Search button 610 with no
search criteria given, then the Search Results box 612 preferably
displays all procedure records in the central database 142.
Alternatively, the correct procedure record may not be found, in
which case the operator may then perform a new search by entering
new search criteria.
[0172] Also, the operator may sort procedure records in Search
Result box 612 by clicking one of the column headings in the Search
Results box 612. This will sort the procedure records using
different criteria. Procedure records may preferably be sorted by
one of the following: Unit Number, Date, Donor ID, or Donor Name
(first name, last name). The first time the column heading is
clicked, the procedure records are sorted in ascending alphanumeric
order. Each subsequent click of a column heading results in
presentation of the records in the opposite alphanumeric order
(ascending or descending). The operator may also view a Lab Results
Entry/Edit Dialog box (see box 701; FIG. 6J) by clicking the
desired procedure record in the Search Results box 612, and then
clicking the Lab button 616 to view the Lab Results Entry/Edit
dialog box 701 (FIG. 6J).
[0173] The operator may preferably access the Finalize Procedure
Information dialog box 621 for a particular procedure using one of
two methods, the Monitor Procedure sub-procedure described above
(see FIGS. 5A-5B), and/or the Select Procedure sub-procedure (FIG.
6A). The operator can access the Finalize Procedure Information
dialog box 621 via the Select Procedure task window 601 (see FIGS.
6A and/or 6B), preferably if the following is true; the procedure
will be run, is currently running, or has been run under control of
the central system 140. Note that while using Select Procedure, the
operator can preferably access the Finalize Procedure Information
dialog box 621 regardless of whether the procedure record is opened
or closed (this is in contrast to Monitor Procedure; the procedure
record must preferably be in open status in order to access it from
the Monitor Procedure task window 501). In addition, once the
procedure has been completed on the apheresis machine 10, the
operator may use the Select Procedure task window 601 to access a
Lab Results Entry/Edit dialog box 701 (FIG. 6J), allowing the
operator to view/enter lab product results.
[0174] Moreover, the operator can preferably access the Finalize
Procedure Information dialog box 621 any time after the Prepare
Procedure Wizard (see description of FIGS. 3B-3F) has been
completed for the donor/procedure. Thus, the operator may enter
procedure information such as supplies and operator roles (see
below) while the procedure is still running. However, even if all
required data has been entered and saved in the procedure record,
the procedure record is not considered closed until after the
apheresis machine run has been completed (i.e., the central system
140 has detected a reboot or similar such signal from the apheresis
machine 10). In addition, in order to update the status of a
procedure record from open to closed, all required information must
be present in the Finalize Procedure Information dialog box.
Required information is preferably either or both dictated by the
central system 140 (unit number, machine ID, donor ID, date), and
determined by the System Administrator during system setup
(required supplies, operator roles, etc.).
[0175] Once the central system 140 changes the status of a
procedure record from open to closed, the central system 140
preferably removes the procedure from the Monitor Procedure list
504 (see FIG. 5A). After this point, the system 140 may require use
of the Select Procedure task window 601 to revisit the procedure
record. Note: a procedure is preferably also removed from the
Monitor Procedure list 504 if a System Administrator forces record
completion using button 511 in FIG. 5A (i.e., when the System
Administrator determines that a record cannot or will not be
closable in accordance with normal procedures as dictated
herein).
[0176] To finalize a procedure, the operator will preferably select
a procedure listed in either the Monitor Procedure window 501 (FIG.
5A) or the Select Procedure task window 601 (FIG. 6A), and then
open the Finalize Procedure Information dialog box 621 (FIGS.
6C-6I). The procedure record for the selected procedure is then
displayed in the Finalize Procedure Information dialog box 621,
preferably in initial form with a Supplies tab 631 as shown in FIG.
6C by default.
[0177] In the top portion 629 of the Finalize Procedure Information
dialog box 621, the operator confirms all preferably required and
pre-populated procedure information, as follows: Unit Number;
Machine ID; Procedure Date; Donor ID; Donor Name; and End Time. All
of the above information is preferably non-editable, and is
preferably downloaded from the central database 142 and/or the
apheresis system 10 run data for this procedure.
[0178] On the Supplies tab 631 (FIG. 6C), the operator may enter
procedure supplies data. The supplies data entries may include the
following: an "X" box or column, and various columns which may
include a Description, a Lot number, an Expiration date, and a
Manufacturer column, inter alia. In the "X" box/column, preferably
the left-most column in the grid, the Administrator preferably
defines which supplies entries are required, using an "X" in this
cell for such required supply information. In the Description
field, which is preferably non-editable as defined by an
Administrator during setup, the Administrator preferably sets up
supplies data by providing supplies descriptions and defining each
supply as an optional or required entry. Each supply description
the Administrator defines preferably appears in the Description
column in the grid. The Lot number is preferably required if any
supplies entry is a required entry. This can be typed into the box,
or alternatively, the operator may use the barcode reader to enter
this data automatically. The Expiration date is also preferably
required if any supplies entry is a required entry. This also can
be typed into the box, or alternatively, entered using a barcode
reader to enter this data automatically. Similarly, the
Manufacturer data is preferably required if any supplies entry is a
required entry. Preferably a drop-down list, editable by selection
only is used for entry here. Alternatively, the operator may use
the barcode reader to enter this data automatically.
[0179] The operator may then optionally click the Operators tab 641
(see FIG. 6D) in the Procedure Data Entry/Edit screen 621 (also
known as the Finalize Procedure Information screen 621; FIGS.
6C-6I) to access the operator role data entry area. Here, the
operator may preferably enter information about operator roles.
Each operator role entry may include the following: an "X" box or
column; a Role column, and Operator ID and Name columns. The "X"
box or column is again preferably the left-most column in the grid,
with the Administrator having pre-defined an operator role entry as
required such that an "X" appears in this cell for that role. The
Role column is preferably non-editable, defined by the
Administrator during system setup. The System Administrator
preferably sets up operator roles data by providing operator role
descriptions and defining each operator role as an optional or
required entry. Each operator role description the Administrator
defines appears in the Role column in the grid. The Operator ID and
Name columns are preferably required if the operator role is a
required entry. These may be drop-down lists, editable by selection
only. When the operator selects an item in the Operator ID
drop-down list, the corresponding Operator Name cell is preferably
automatically populated with the operator's first and last names.
Alternatively, an operator name can be typed in the box, but it
reverts to match the currently selected operator ID the next time
the procedure record is displayed.
[0180] The operator may then optionally click the Donor Information
tab 651 in screen 621 (FIG. 6E) to view the donor information for
this procedure. The donor information is preferably supplied from
the central donor database 142 and/or the blood bank information
system, as well as information entered during the Prepare Procedure
Wizard for this procedure. Once the central system 140 creates a
procedure record for a procedure, the donor information becomes a
part of the procedure record, providing a snapshot of this
information on the date the procedure was run. This information is
therefore preferably non-editable. The donor information preferably
includes the following: Gender; Height; Weight; TBV (Total Blood
Volume); Blood Type (if available); CMV and HLA status (if
available); and Pre-procedure values for hematocrit and platelet
count. In addition to the above information, this tab 651
preferably also shows the post-procedure values for hematocrit and
platelet count. This information is preferably provided from the
apheresis system 10 run data for this procedure and thus, like the
other information in this tab, these values are preferably
non-editable.
[0181] The operator may then also optionally click the Record
Status tab 661 in screen 621 (FIG. 6F) to view the current central
system procedure record status. The status options preferably
update automatically during the procedure run and procedure record
entry. The options, which are preferably non-editable within this
module, may include the Procedure Record, the Machine Release, the
Visit Status and the Reason. The Procedure Record preferably
remains Opened until all required information has been entered in
the procedure record; at that point, the central system may update
this option to Closed. A check box can be used to indicate whether
the machine has been released for the next donor. The Visit Status
preferably shows the current status of the donor's visit, for
example. If the procedure is currently running, this box shows the
same status that is shown in the Monitor Procedure task window 501
(FIG. 5A) for this procedure). The Reason field may preferably be
used to indicate whether and/or if the donor was removed from the
Donor Assignment Queue 406 in the Assign Machine task window 401
(FIG. 4A) for any reason (incomplete procedure, dismissed at the
apheresis system 10, etc.); the reason being displayed in this
box.
[0182] The operator may then optionally click the Procedure Log tab
671 (see FIG. 6G) to view the procedure name and the procedure log
(an event log of all machine alerts, alarms, warnings, and operator
adjustments entered throughout the procedure). Procedure comments
that have been entered by a system operator may be intermixed
(according to timestamp) with the other information in this
scrollable region. This information is preferably variable for
active donations and remains at the final status display for
pending and finalized procedures. The information is preferably
non-editable and is preferably supplied by the apheresis machine 10
run data and by the operator entering procedure comments either in
this dialog box 671 or via the Monitor Procedure task window 501
(FIG. 5A). The operator may optionally click the Comment button to
enter a comment in the procedure record for that procedure. An
Enter Procedure Comment dialog box (not shown) may be made to
appear. The operator can select a comment from the pre-configured
comment list (preferably created by the Administrator) and/or enter
a free-form text comment entry. If the operator clicks the OK
option, the Finalize Procedure Information dialog box 621,
Procedure Log tab 671 is redisplayed, showing the date and time the
comment was created, as well as the user ID for the user who was
logged on when the comment was created. If the operator clicks
Cancel, the Finalize Procedure Information dialog box 621,
Procedure Log tab 671 is redisplayed, but the comment is not
included in the procedure record.
[0183] The operator may then optionally click the Run Summary Tab
681 (FIG. 6H) to view the machine-estimated product volume
information. This information is preferably provided by the
apheresis machine 10 after the run is complete. Until the procedure
is completed, all of the fields in this tab are blank. The
information would then be non-editable and defaulted from the
procedure run data (machine run summary). This information
preferably includes the following: the estimated volume for
platelet, plasma and RBC products; the AC volume in platelet,
plasma and RBC products; the estimated yield for platelet products;
the total AC volume used; the AC administered to the donor during
the procedure; the total blood volume processed; and Summary
remarks, preferably including one or more of the following: a
reminder to label LRS platelet product as having less than
1.times.10e6 white blood cells (if so leukoreduced, as on the Trima
system 10; a reminder to count the product; a reminder to verify
platelet yield; a reminder to verify platelet volume; a reminder to
determine whether platelet concentration is out of range; a
reminder to verify plasma volume; and/or a reminder to verify RBC
product.
[0184] The operator may then optionally click the Blood Loss Tab
691 (FIG. 61) to view blood loss entries. Blood loss information
preferably includes the Product, the Tubing Set Residual, the Blood
Sample and an Other column. A check box for Rinseback Completion is
also provided. In more detail, the Product column shows product
volume for plasma and RBCs. This information is preferably
downloaded from the apheresis system 10 run data for this
procedure, and is preferably non-editable. The information is
determined based on the procedure that was run and the donor's
hematocrit. Until the procedure is completed, these fields are
blank. The Tubing Set Residual preferably shows the volume of
plasma and RBCs remaining in the tubing set. This information is
also preferably downloaded from the apheresis system run data for
this procedure, and is preferably non-editable. During the
procedure, this information is determined based on the collection
status, the tubing set type, the procedure that is being run, and
the donor's hematocrit. When the procedure is completed, this
information is determined based on all of the above, as well as
whether or not rinseback was completed for the procedure. The Blood
Sample column presents the volume of blood, entered by operator for
plasma and/or RBCs, according to the facility's SOPs. The default
value if, used, is preferably specified by the Administrator. The
Other column includes any Other volume of blood (for example,
estimated volume of a spill), entered by operator for plasma and/or
RBCs, according to the facility's SOPs. The Donor Completed
Rinseback check box is checked if rinseback was completed for the
procedure. Until the procedure is completed, this box remains
unchecked. This information is also preferably downloaded from the
apheresis system run data for this procedure, and is preferably
non-editable.
[0185] After entering and/or confirming the above data
(particularly as may be required by the SOP's of a particular blood
center), the operator may then click the "OK" button 622 (FIGS.
6C-6I) to save the record. The central system 140 saves the
procedure record. If all the required information has been entered,
the central system 140 updates the status of the record to be
closed. The central system 140 may then also close the Finalize
Procedure Information dialog box 621 and redisplay either the
Monitor Procedure task window 501 (FIG. 5A) or the Select Procedure
task window 601 (FIG. 6A), depending on the method the operator
originally used to open the Finalize Procedure Information dialog
box 621.
[0186] Alternatively, the Operator may click the Apply button 624,
at any point while the Finalize Procedure Information dialog box
621 is displayed to save the data in the procedure record up to
that point, without closing the dialog box 621. The central system
140 saves the procedure record and, if all the required information
has been entered, the system 140 updates the record's status to
closed. Similarly, at any point while the Finalize Procedure
Information dialog box 621 is displayed, the operator may click the
Cancel button to cancel the current entry session. The central
system 140 may then discard all unsaved changes in the procedure
record, and close the Finalize Procedure Information dialog box 621
and redisplay either the Monitor Procedure task window 501 or the
Select Procedure task window 601, depending on the method the
operator used to open the Finalize Procedure Information dialog box
621.
[0187] Various alternative actions are also available. For example,
the Operator may view a record for a procedure that has not yet
begun. The central system 140 creates a procedure record as soon as
the operator completes the Prepare Procedure Wizard for a procedure
(see FIGS. 3B-3E). However, the procedure does not appear in the
Monitor Procedure task window until the donor and procedure
information is downloaded to the assigned apheresis system 10.
Prior to that time, if the operator wants to view the procedure
record, he/she can search for the procedure record using the Select
Procedure task window 601. The operator may also view and/or edit
information in the Finalize Procedure Information dialog box 621,
as described here; i.e., at any point in the overall process,
however, in most instances, doing so at before a process has begun
or during the process would be premature.
[0188] However, Lab data entry/edit may also be performed from
screen 601 (as introduced above) at any time in the overall
process; generally after such data has been processed and returned
from the Laboratory. Again, the Lab Data Entry/Edit screen 701
(FIG. 6J) is preferably accessed by selecting the Lab button 611 in
screen 601 (FIG. 6A). Then, lab information may be entered/edited
in screen 701 according to the product types (see the three tabs
for Platelet Products, Plasma Products and Red Blood Cell
Products). Then, Lab data entry/editing may be performed according
to the information on hand. For example, Collected Product
information can be entered/edited (although this information may be
downloaded from the apheresis machine 10, and thus may be made
non-enterable/non-editable, here); Residual Count information can
be edited/edited (as may be applicable); and Split Product
information may be entered/edited (Split ID numbers;
concentrations, bag weights, volumes and/or yields, e.g.),
here.
[0189] During use of the Select Procedure task window 601, the
operator may click one of the column headings in a grid to sort the
entries using different criteria. The first time the column heading
is clicked, the entries are sorted in ascending alphanumeric order.
Each subsequent click of the column heading results in the opposite
alphanumeric order (ascending or descending).
[0190] Note: the donor may be dismissed at the machine 10 after the
central system has initiated a record. In such a case, the central
system 140 preferably automatically closes the procedure record if
both of the following are true: The donor is assigned to an
apheresis system, but then is dismissed using the apheresis system
touch-screen display 199 before the procedure is begun; and, the
operator does not assign the donor to a different machine 10, but
instead removes the donor from the Donor Assignment Queue 406 in
the Assign Machine task window 401 (See FIG. 4A). For more
information, see the following alternative actions described
relative to the "Assign Machine" sub-procedure relative to FIGS. 4A
and 4B.
[0191] The central system may also detect an Incomplete Run, in
which case, the system 140 preferably automatically closes the
procedure record if both of the following are true: the donor is
disconnected from the apheresis system 10 and the operator
indicates on the machine that the run is incomplete, and the
operator has completed all information necessary to finalize the
procedure record. If the operator has not yet completed all
information necessary to finalize the procedure record, the
procedure record remains opened until such information has been
entered, as described, above.
[0192] Note, throughout the descriptions of preferred options
above, there are set forth a plurality of described instances of
data/information preferably being communicated to and from the
central system 140 from and to the apheresis system(s) 10.
Nevertheless, it is understood that not all of these particular
types of data or information may be used or captured or
communicated by many available blood processing systems. Thus, it
should be understood that all such instances in the above
description are intended as the preferred embodiment, and that
lesser direct communications and mere manual data transfer from and
to a central system 140 and associated blood processing systems 10
are also intended within the scope of the present invention. Thus,
for example, data may be manipulated and/or optimized on/in a
central system 140, and the results of which may not be readily
transferred to a blood processing system 10 (see perhaps systems
10B and/or 10C as shown in FIG. 1B, e.g.), and therefore the
resulting manipulated and/or optimized data or information may have
to be operator entered into such a system 10 for use thereby.
Similarly, the results of the processing/collection procedure
performed by a lesser compatible system (see again, perhaps systems
10B and/or 10C, e.g.) may not be automatically communicated to the
central system 140, but may be operator transferred (i.e., manually
entered) upon procedure completion. Instances of preferably
non-editable fields or data, as set forth above, would thus not be
applicable here. Rather, such data fields would indeed be
editable/enterable depending upon which type of blood processing
system 10 was being used. A further similar process for data
handling may be performed for whole blood collection systems (see
e.g., the whole blood representation 10D in FIG. 1B), wherein a
data-communicating machine is often not used (at least not in the
initial collection process; a needle connected to a receptacle/bag
by a tube may be the collection device 10D). However,
data/information may still be captured by manual data entry
throughout the process, for example, from initial Reception and
Screening through to Collection completion. Moreover, subsequent
(or chair-side, or bed-side) processing may even be performed such
as to separate the collected whole blood into components, which may
be desirably tracked in a central system 140. The data would rather
only be manually entered, or perhaps even certain subsequent (or
chair-side, or bed-side) processing machines may have data
communication abilities so as to communicate with a central system
140. The quantity and/or quality of data would then only differ as
to the type of procedure performed (e.g., whole blood separated
into which components).
[0193] Lastly, if the operator desires to view and/or print an
End-of-Run report when the procedure is complete, he/she may do so
using the Reports feature of the Everest software (see generally
FIGS. 6K, 6L and 6M, for example). Various pre-defined and/or
system administrator defined reports can be generated about donors,
procedures and collected blood products, inter alia. The reports
command may be an icon in the icon task bar 205 (though not shown
as such here), or may be accessible through the Tasks menu 216 (see
FIG. 2A, e.g.), inter alia. A list of previously configured reports
may then be made to appear as for example is shown in dialog box
711 of FIG. 6K. Upon selection of a report from the list in box
711, a report generating dialog box such as box 721 (FIG. 6L) may
then be made to appear. After entry of the prompted-for
information, a report may then be generated. An example report is
shown in the report preview screen 731 (FIG. 6M). The presently
preferred report generator is based on the Oracle Reports platform,
which is a readily available software application (from the Oracle
Corporation, Redwood Shores, California). Thus, data from the
central may be transferred to such a Report generating platform to
create reports of any desirable format in fashions known and
understood by those skilled with Oracle Reports or like software
applications.
[0194] As mentioned throughout, an important element of the overall
system 140 is the communication subsystem 146, which provides
communication between and/or among the various other
devices/elements. As described above, subsystem 146 may involve
hardwire or cable connections between the various elements; and/or
it may involve other devices and/or software. A further
communication alternative with the computer/database 140 may
generally involve the internet. As is known in the art, the
internet provides a "common language" through which multiple
different systems can communicate without requiring special
tailoring of each system. For instance, various protocols have been
established to facilitate data communication on what has become
known as the internet. In particular, the TCP-IP (Transmission
Control Protocol--Internet Protocol) is an internet protocol
structure which was developed in a 1973 Department of Defense
research project designed to link a "network of lowest bidders";
now in wide commercial usage since about 1988. In particular, the
TCP ensures that the information goes to its destination correctly;
verifies the correct delivery of data from client to server; and
provides a common way of sharing information among different types
of systems (PC, MAC, SUN workstation, etc.). Further, the IP also
ensures the information goes to the right location; moves packets
of information from node to node; and provides unique IP addresses
assigned by InterNIC (NSF, AT&T, & Network Solutions, inter
alia.). The Internet then provides a web of information, which can
be accessed through a single interface (web browser). The internet
can also provide a communication medium between a computer/database
system 140 and various other computer information systems such as
those shown in FIG. 1B; and ostensibly provide communication
protocols to or with the apheresis machines 10 as well.
[0195] As an example, as inventory is withdrawn or replenished
within the hospital or blood bank, this information can be recorded
via bar code. By connecting the information to the hospital
information system (HIS) and on through to www.bloodaccess.com, or
a like internet connection address, a blood donation center can
then access and monitor local inventory levels. When one hospital
needs a stat or immediate order for a given blood component, the
blood center may then locate and arrange transfer of the units from
one center or one hospital to another. The blood center can then
replenish the units taken from the hospital within a short period
of time (such as 24 hours) using flexible collection through
automation. Moreover, this is not merely an inventory tool, it may
also be tailored to fill specific needs such as in the "dosing"
model introduced herein.
[0196] Similarly also, donor recruitment and/or eligibility and/or
qualification can be run by a centralized system to determine which
donors may be able to provide certain products at a certain time.
The data may be obtained by data input as above, or with data
already existing in the memory 142 and/or as may be obtained by
communication with a discrete information system. Most preferably,
these procedures could be performed without the specific potential
donor present to predict what the donor could yield, and then if a
desirable product is predicted (i.e., the potential donor is
eligible or qualified to give the desired product(s)), the
potential donor could then be contacted to recruit them to undergo
the procedure. In this fashion, a blood center could better tailor
its blood and blood component supply to better match demand.
[0197] By way of background and provision of a detailed application
of the present invention, a description of the blood apheresis
process and associated machinery will now be set forth. Various
embodiments of blood component collection assemblies may
incorporate principles of the present invention. However, as noted
above on-line techniques have been determined to be quite effective
and thus the present invention is being described with reference to
such techniques. One embodiment of an on-line technique and
attendant apparatus which may be incorporated into the blood
component collection system 2 of FIG. 1A is illustrated in FIG. 7A.
An on-line technique herein refers to the use of a blood processing
device which is controlled by parameters entered directly therein
and calculated or manipulated thereby to achieve all necessary
control parameters. Off-line techniques refer to the use of data
entry and/or data manipulation performed by devices not resident on
or within the particular blood processing device; though which are
preferably disposed in data communication therewith.
[0198] The blood component collection assembly 10' of FIG. 7A
utilizes an on-line technique in that a donor 14 (e.g., the whole
blood source) is directly integrated with the system 10' by fluid
interconnection with the blood component collection device 18. This
particular on-line technique is more particularly referred to as a
dual needle configuration since there are two fluid
interconnections between the donor 14 and the blood component
collection device 18.
[0199] The donor 14 is fluidly connected to the blood component
collection device 18 by an inlet line 22 and appropriate needle
assembly (not shown). Whole blood from the donor 14 is thus
continuously provided to the blood component collection device 18
through the inlet line 22 for separation of the desired blood
component(s) therefrom, utilizing an inlet pump 26 (e.g., a
peristaltic pump) to maintain this flow if desired/required. Prior
to the blood of the donor 14 entering the blood component
collection device 18, anticoagulant from an anticoagulant ("AC")
container 30 may be provided to the whole blood, utilizing an AC
pump 32 (e.g., a peristaltic pump) to maintain this particular flow
if desired/required. Consequently, the inlet flow to the blood
component collection device 18 typically includes both a flow of
whole blood from the donor 14 and a flow of anticoagulant from the
AC container 30.
[0200] The blood component collection device 18 separates the whole
blood provided on-line by the donor 14 into three primary
constituents, namely platelets, a combination of red and white
blood cells ("RBC/WBC"), and plasma. The platelets collected from
the blood component device 18 are directed through a platelet
collect line(s) 34 to one or more platelet collect bags 38 via a
collect pump 36. The plasma and RBC/WBC are provided back to the
donor 14 through a plasma line 42 and RBC/WBC line 46,
respectively, both of which are interconnected with a second needle
assembly (not shown) on the donor 14 via a donor return line 50.
The plasma line 42 includes a plasma pump 40 (e.g., a peristaltic
pump) to maintain the flow of plasma if desired/required. Although
plasma may be provided back to the donor 14 in the above manner, it
may be desirable to collect the separated plasma in some cases. In
this regard, a plasma collect bag 54 may be provided and
interconnected with the plasma line 42 (interconnection shown in
phantom). In this case, appropriate valving 56 may be incorporated
in the plasma line 42.
[0201] The blood component separation assembly 10'' of FIG. 7B is
similar to that of the dual needle configuration of FIG. 7A except
that a single needle assembly (not shown) integrates the donor 14
within the blood component collection assembly 10''. Consequently,
similar components are similarly identified where appropriate. With
regard to the single needle configuration of FIG. 7B, whole blood
of the donor 14 initially flows through a donor access line 62 and
into an inlet line 66 which is fluidly connected with the blood
component collection device 18 such that the platelets are
separated and collected in the above-described manner. The plasma
and RBC from the blood component collection device 18 flow through
the plasma and RBC/WBC lines 42, 46, respectively, both of which
are fluidly interconnected with a return flow controller 74. As
above, however, the plasma may alternatively be directed to a
plasma collect bag 54. In the event that plasma is not collected,
the RBC/WBC and plasma are provided back to the donor 14 through
the return flow controller 74 via a donor return line 70, which is
interconnected with the donor access line 62. As can be
appreciated, since only a single line is directly connected to the
donor 14, namely the donor access line 62, blood is either being
removed from or provided back to the donor 14 such that the
procedure is effectively two-step versus continuous in relation to
the donor 14.
[0202] An exemplary blood component collection device 18 which may
be used in the blood component collection assembly 10 is more
particularly illustrated in FIGS. 8A-8B. This and like devices 18
are the subject of various U.S. Patents, see particularly No.
4,387,848 to Kellogg et al., entitled Centrifuge Assembly, issued
Jun. 14, 1983, and U.S. Pat. No. 4,708,712 to Mulzet, entitled
Continuous-loop Centrifugal Separator, issued Nov. 24, 1987; inter
alia, the disclosures of which are incorporated by reference in
entireties herein. Such devices 18 are also commercially available
from the assignee of the present application as such may be
incorporated in the COBE Spectra and/or Trima apheresis
systems.
[0203] Referring to FIGS. 8A-8B, the blood component collection
device 18 utilizes a processing channel 80 to provide the desired
disposable extracorporeal circuit. The channel 80 is positioned
preferably within a groove formed directly or indirectly in a
centrifuge rotor (not shown) (e.g., a separate filler may receive
the channel 80 and be attached to the centrifuge rotor), and is
illustrated in the two-stage shape, which it assumes during
processing (i.e., during flow of blood therethrough). Although a
two-stage channel 80 is shown and described further herein, the
present invention is not so limited; rather, the present invention
may be used also with single-stage and/or any other centrifugal
configuration as well as with non-centrifugal separation machines
or devices.
[0204] As shown and described herein, the two-stage processing
channel 80 generally includes a first stage 84 for collectively
separating red blood cells ("RBC") and white blood cells ("WBC")
from platelet-rich plasma, a second stage 92 for thereafter
separating platelets from the platelet-rich plasma, a transition
portion 88 defining a separation between the first stage 84 and
second stage 92, and a control chamber 124 for maintaining a proper
interface between the first stage 84 and second stage 92, namely
the position of the interface between the RBC/WBC and platelet-rich
plasma within the transition portion 88.
[0205] The first stage 84 extends from one end of the control
chamber 124 along an arcuate path generally inwardly, toward the
axis 132 about which the processing channel 80 rotates via the
centrifuge rotor, until terminating at the transition portion 88.
Specifically, the end of the first stage 84 adjacent the control
chamber 124 is positioned at a greater radial distance from the
axis 132 than the end of the first stage 84 adjacent the transition
portion 88. An inlet tube 96 is fluidly connected with the first
stage 84 between its two ends to introduce whole blood into the
processing channel 80 and a RBC/WBC tube 100 is provided in the
control chamber 124 for removing the separated RBC/WBC from the
channel 80. Both the inlet tube 96 and RBC/WBC tube 100 extend
externally of the rotatable device 18 for interconnection with the
donor 14 and/or collection bags 38, 54.
[0206] As RBC/WBC sediment against the outer wall in the first
stage 84 during rotation of the centrifuge rotor they are directed
and counterflow toward the RBC/WBC tube 100 for removal from the
channel 80 due to the increased centrifugal forces at the RBC/WBC
tube 100 in comparison with the transition portion 88. That is,
since the first stage 84 extends along an arcuate path generally
outwardly away from the axis 132 proceeding from the transition
portion 88 to the control chamber 124, the centrifugal force
differential along the first stage 84 establishes the described
counterflow of the separated RBC/WBC. Moreover, the transition
portion 88 also assists in providing for this counterflow since it
extends along an arcuate path generally inwardly toward the axis
132 proceeding from the first stage 84 to the second stage 92.
[0207] The platelet-rich plasma, which has a lower density than the
RBC and WBC, flows beyond the transition portion 88 from the first
stage 84 into the second stage 92 for further processing, while the
RBC/WBC are directed back toward the RBC/WBC tube 100 in the
above-described manner. The second stage 92 initiates at the
radially inwardmost part of the transition portion 88 and extends
along an arcuate path generally outwardly away from the axis 132 to
a platelet collection chamber 104. Platelets are removed from the
processing channel 80 at the platelet collection chamber 104 by a
platelet tube 108 which interfaces with the outer wall of the
processing channel 80 at the platelet collection chamber 104.
Thereafter, the second stage 92 extends along an arcuate path
generally inwardly toward the axis 132 until terminating at the
plasma tube 112. Both the platelet tube 108 and plasma tube 112
extend externally of the rotatable device 18 for interconnection
with the platelet collect bag(s) 38 and donor 14/plasma collect
bag(s) 54, respectively.
[0208] Platelets which do not separate from the plasma in the
initial portion of the second stage 92 between the transition
portion 88 and platelet collection chamber 104 are separated in the
portion of the second stage 92 between the platelet collection
chamber 104 and the plasma tube 112. These platelets will flow back
towards the platelet collection chamber 104 in the opposite
direction of the flow of platelet-rich plasma/platelet-poor plasma
through the second stage 92 due to the configuration of this
portion of the second stage 92. That is, the platelet collection
chamber 104 assumes the radially outwardmost position in the second
stage 92 such that all platelets, regardless of where separation
occurs in the second stage 92, flow towards the platelet collection
chamber 104 for removal from the channel 80.
[0209] Platelet-poor plasma exits the second stage 92 and flows out
through the plasma tube 112, which interfaces with the inner wall
of the processing channel 80 and/or continues to flow through the
remaining portion of the processing channel 80 to the control
chamber 124. Plasma which flows to the control chamber 124 exits
the channel through the control tube 114, which joins with the
RBC/WBC tube 100 into a single outlet tube 120. The positions and
diameters of the RBC/WBC tube 100 and control tube 114 and the
joinder of such into the common outlet tube 120 regulate the
position of the RBC/WBC-platelet-rich plasma interface within the
transition portion 88 using conservation of mass principles.
[0210] As noted above, each blood component collection device 18
may include a prediction model appropriately interfaced with the
operator input module 16 and/or disposed on or within the
manipulation device 144 or in an associated memory device 142 as
shown in FIGS. 1A-1D any and/or all of which may be used to
configure the prediction model and/or to allow operator input of
various parameters to be used by the prediction model for
predicting a yield of a particular blood component to be collected
before a collection procedure is initiated using a compilation of
algorithms. The preferred prediction model and the optimization
algorithms which are associated with the present invention are
described in detail in U.S. Pat. Nos. 5,496,265; 5,658,240;
5,712,798; and 5,970,423; inter alia, all of which being commonly
assigned to the assignee of the present invention, the disclosures
of which being incorporated herein in their entireties as if fully
set forth here by this reference thereto. The algorithms and
disclosures thereof will thus be only briefly described herein.
[0211] The prediction model is typically configured by the site
(e.g., the blood bank/center) for a particular blood processing or
component collection procedure (e.g., single or dual needle) used
by the site. Both single-needle and double needle procedures as
shown in FIGS. 7A and 7B will be used in the following general
description, particularly in relation to a platelet-collecting
procedure (although of course, any collection procedure can be
understood as being substitutable herein). In this regard, an AC
infusion rate (i.e., the rate at which anticoagulant is provided to
the donor 14 per the blood volume of the donor 14) and the AC ratio
(i.e., the collective flow of AC and blood through the inlet line
22 in relation to the flow of AC through the line 22) must be
specified (through configuration or modified input as will be
discussed below). Moreover, in the event that plasma is to be
collected into the plasma collect bag 54 in the collection
procedure, the maximum amount of plasma which should be collected
considering the medical and physical characteristics of the donor
14 must also be provided.
[0212] And, as described in the above-mentioned patents, there are
two alternatives for establishing the plasma volume limit. These
will not therefore be described further here.
[0213] Further information is required by the prediction model
prior to performing its yield prediction function. For instance,
the total procedure time is typically input by the operator or
pre-configured by the site (e.g., the blood bank/center). Moreover,
the total procedure time may be affected by whether a stepdown
option is utilized for the blood component collection device 18 so
as to enhance separation of the various blood components. When this
stepdown option is selected, the angular velocity of the blood
component collection device 18 is incrementally reduced during the
platelet-collection procedure. For instance, the stepdown option
could provide for angular velocities for the device 18 of 2400,
2200, and 2000 RPM, each of which would be for a specified
duration.
[0214] Based upon the foregoing, the configuration of the
prediction model in relation to the blood component separation
assembly 110' and associated protocol in effect standardizes site
protocol for purposes of "normal" operations. However, for a
particular donor 14 it may be desirable to alter the
"configuration" for one processing run. Consequently, the
prediction model may utilize a procedure in which certain
parameters utilized in the following equations may be adjusted on a
one-at-a-time basis. Such is referred to as modified input data and
the associated parameters are procedure time, inlet flow rate to
the device 18, AC ratio option, the desired platelet collect
volume, the desired platelet collect concentration, and the desired
source plasma volume to be collected. Moreover, other parameters
such as AC infusion rate, stepdown option (yes or no), needle
option (single or double), and high flow option (yes or no) may
also be entered as modified input data by an operator.
[0215] Having configured the prediction model in the
above-described manner, the following additional information is
provided and is utilized in the various calculations of exemplary
Equations 1-22 presented below: (1) needle option, namely whether
the procedure is dual needle (FIG. 7A) or single needle (FIG. 7B);
(2) run identification number for purposes of associating the
data/output generated by the various equations with a particular
donor 14 and processing run; (3) the gender of the donor 14; (4)
the height of the donor 14; (5) the weight of the donor 14; (6) the
total blood volume as calculated in Eq. 10 below; (7) the
hematocrit of the donor 14, either based upon an initial estimation
and thereafter updated based upon analysis of the donor's 14 blood
sample (e.g., by a cell counter) or input directly from such an
analysis; (8) the platelet pre-count, either based upon an initial
estimation and thereafter updated based upon analysis of the
donor's 14 blood sample (e.g., cell counter) or input directly from
such an analysis; and (9) whether plasma collection is desired in
conjunction with the platelet collection.
[0216] Based upon the above initial configuration and subsequent
data input (except when entered as modified input data), the
following output is generated by the prediction model: (1) platelet
yield; (2) inlet flow rate; (3) AC ratio; (4) procedure time; (5)
platelet collect volume; (6) platelet collect concentration; (7)
source plasma volume; (8) AC in the platelet and plasma collect
bags 38, 54; (9) platelet post-count; (10) AC infusion rate; and
(11) output approval. This information is utilized at least in part
in the following equations to generate, inter alia, the predicted
platelet yield value of the collected platelets for the case of the
dual needle procedure of FIG. 7A and also for the case of the
single needle procedure of FIG. 7B. The differences between those
procedures with regard to the prediction model are identified
herein. As will be appreciated, some of the equations are utilized
in the calculation of the predicted platelet yield, whereas other
equations are used to generate additional information for output
and informational purposes. The variables or parameters and the
units associated therewith of the equations are presented after the
equations in the Variables Index.
[0217] Platelet Yield:
Y=1.times.10.sup.6C.sub.PRV.sub.BF.sub.Y[1-exp[-E.sub.C(f.sub.BP-0.12)]]
(Eq. 1) F.sub.BP=(Q.sub.INt.sub.E+50)(1-1/R)/V.sub.B (Eq. 2) and
where: Q.sub.IN=RQ.sub.AC=0.001IV.sub.BPR.ltoreq.150 (Eq. 3)
[0218] Alternatively, the platelet yield may be expressed as:
Y=1.times.10.sup.6C.sub.PRV.sub.BF.sub.Y[1-exp[-E.sub.C(0.001I(R-1)Pt.sub-

E.sub.c=C.sub.1-C.sub.2exp[9.91(1-1/R)H]Q.sub.INA.gtoreq.0 (Eq. 5)
where the constant C.sub.1 is defined as follows:
C.sub.1=0.803--dual needle, without stepdown C.sub.1=0.840--dual
needle, with stepdown where the constant C.sub.2 is defined as
follows: C.sub.2=4.08.times.10.sup.-5--dual needle, without
stepdown C.sub.2=8.54.times.10.sup.-5--dual needle, with stepdown
and where: Q.sub.INA=Q.sub.IN(t.sub.E/t.sub.P) (Eq. 6)
[0220] In Eq. 6, t.sub.p may be provided as configuration data or
modified data as provided above, or alternatively may be derived
from the solution of Eq. 4 for t.sub.E.
[0221] Effective Procedure Time: t.sub.E=t.sub.P,
Q.sub.IN.ltoreq.45 t.sub.E=t.sub.p-50(1/45-1/Q.sub.IN),

[0222] Only high-flow protocol is used for Q.sub.IN>45.
[0223] AC Infusion Rate Constant: I=1000Q.sub.IN/(PRV.sub.B) (Eq.
8)
[0224] Alternatively to the use of Eq. 8 for the derivation of the
AC infusion rate constant I, such may be provided as configuration
or modified input data pursuant to the above.
[0225] AC Ratio:
[0226] Initially, the AC ratio may be provided as configuration or
modified input data pursuant to the above. In configuration, it is
defined as follows: R=1+2.51/H low R=1.33(1+2.51/H)medium
R=1.67(1+2.51/H)high (Eq. 9)
[0227] Total Blood Volume: V.sub.B=604+0.006012L.sup.3+14.6W
ml(male) (Eq. 10) V.sub.B=183+0.005835L.sup.3+15.0 W ml(female)
[0228] Plasma Collect Factor:
[0229] AC infusion rate control maintains the AC flow to the donor
as: Q.sub.ACD=0.001 IV.sub.B (Eq. 11) where the inlet flow
associated with this is: Q.sub.INO=RQ.sub.ACD=0.001 IRV.sub.B (Eq.
12)
[0230] Q.sub.IN is proportional to the total AC flow, as given by
Eq. 3, which includes the AC that flows to the platelet collect bag
38 and the plasma collect bag 54. P (Eq. 13) is the factor by which
QIN is increased by collecting AC, relative to not collecting AC.
That is, P=Q.sub.IN/Q.sub.INO=(average Q.sub.AC)/Q.sub.ACD (Eq. 13)
where:
P=1+(f.sub.ACD/Q.sub.ACD)[V.sub.C/(t.sub.P-150/Q.sub.IN)+V.sub.SP/(t.sub.-
P-500/Q.sub.IN)] (Eq. 14) and where: f.sub.ACP=[(R-1)(1-H)].sup.-1
(Eq. 15)
[0231] Platelet Collect Volume:
V.sub.C=1.times.10.sup.-6Y/[C.sub.B(1+f.sub.ACP)] (Eq. 16)
[0232] Source Plasma Volume:
[0233] The four choices are provided as follows:

[0237] A warning is given if C.sub.PO<100.
[0238] Collect Volumes V.sub.CB=V.sub.C(1+f.sub.ACP) (Eq. 21)
V.sub.SPB=V.sub.SP(1+f.sub.ACP) (Eq. 22)
[0239] The primary equation to be solved for purposes of the yield
prediction by the prediction model is Eq. 4. Consequently, Eqs. 1-3
and 5-22 are ancillary to Eq. 4 although they may be used to
calculate other output data and/or information required by Eq. 4.
With regard to the manner in which Eqs. 1-22 are solved, all the
iteration loops are preferably based on the technique of successive
approximation, in which each iteration is a repeat of the previous
one, but using updated parameter values calculated in the previous
iteration. This process continues until all the convergence
criteria are met. The convergence criteria are that, on successive
iterations, the variable difference is .ltoreq.1 for V.sub.c,
.ltoreq.0.2 for t.sub.E, and <0 for C.sub.B.
[0240] As noted above, the foregoing was based upon a dual needle
configuration as illustrated in FIG. 7A. In the event that a single
needle configuration such as that illustrated in FIG. 7B is
utilized, the following Eq. 7' is used in place of Eq. 7 and the
constants C.sub.1 and C.sub.2 for Eq. 5 are as follows:
C.sub.1=0.803 C.sub.2=8.54.times.10.sup.-5 t.sub.E=t.sub.P,
Q.sub.IN.ltoreq.20 t.sub.E=t.sub.P-215(1/20-1/Q.sub.IN),

[0275] As noted above, the computer/database assembly 140
associated with principles of the present invention interfaces with
or at least provides information to one or more blood component
collection assemblies 10 to provide a blood component collection
system 2. That is, although there are definite advantages to having
an interface between the computer/database assembly 140, and the
blood component collection device 18, the optimization procedure
may be performed at any location and input into the blood component
collection device 18 in any manner. Since the general principles of
the blood component collection assembly 10 were described with
relation to the collection assemblies 10', 10'' (FIGS. 7A and 7B)
which included the blood component collection device 18 and its
various features, the computer/database assembly 140 will be
described in relation to such assemblies 110', 10''. However, it
will be appreciated that the fundamental optimization principles of
the present invention are not limited to these collection
procedures and/or apparatus.
[0276] As noted (FIGS. 1A-1D), the computer/database assembly 140
generally includes a central station 148, as well as a manipulation
device 144 and a memory device 142 (not separately shown).
Initially, it should be noted that the manipulation device 144 is
preferably separate from the internal control of the blood
component collection device 18. Device 18 also preferably remains
accessible by the operator interface device 16 (which could include
the touch screen introduced above). However, typically the
manipulation device 144 will be integrated with (e.g., put in data
communication relationship with) this internal control device 16.
The central memory device may also be separate from the central
manipulation device 144 (as well as from the individual blood
processing machines 10 and/or their control elements 16). The
memory device need only be put in data communication relationship
with the data manipulation device 144 and/or one or more control
elements of the central computational/database assembly 140 and/or
one or more blood processing machines 10.
[0277] Referring now to FIG. 9A, the computational/database
assembly 140 will be described with regard to a standard exemplary
procedure. The central input station 148 will typically be used by
blood banks/centers as the primary means for donor data input and
donor data management. As introduced above in the relation to FIGS.
2A-2E, information relating to a donor such as gender, height,
weight, total blood volume, blood type, temperature, pressure and
demographics will preferably be input at the central input station
148, or could be easily downloaded to the computer/database
assembly 140 from a disparate system such as systems 3 and/or 4 as
shown in FIG. 1B. Moreover, information relating to the donor's
hematocrit and a blood component pre-count (such as platelet
pre-count), both of which may be obtained from a donor blood sample
and determined by known techniques such as cell counters, may also
be entered at the central station 148. In addition to donor-related
data, the particular type of collection procedure to be used for
the donor (e.g., single needle or double needle) may be
input/confirmed at the central input station 148. These also could
be downloaded from a disparate system. Based upon this information
and certain site-standardized conditions (e.g., total procedure
time, collection efficiency, AC infusion rate), an initial
procedure order is thereafter generated preferably by the
manipulation device 140, which specifies the various process
control parameters associated with the selected collection
procedure.
[0278] The initial procedure order may be transferred/down-loaded
onto the internal control of a blood component collection device 18
by a computer network system (FIGS. 1A and 1B) or by other methods
such s floppy disk transfer (not shown). The operator interface
module 16 may be used to assist this process if required/desired.
When this operator interface module 16 exists, it may of course
still be used as an alternative for the initial donor data input
and/or to generate the initial procedure order including
optimization and thereby alleviate the need for a central input
station 148. However, it is believed that it will be more efficient
to use the central input station 148 and the associated central
data manipulation device 140, preferably in conjunction with the
central memory database. Although this initial procedure order may
be used in the collection process, the initial procedure order may
also be optimized in accordance with principles of the present
invention to obtain one or more optimal values for the process
control parameters. This optimization may also be performed on the
individual blood processing machines 18, but is preferably
conducted on/by the central data manipulation device 140. As noted,
this optimization process may be utilized before the collection
procedure is actually initiated, but may also be initiated during a
given collection procedure and such is referred to as downstream
optimization although if performed after initiation, and though
possibly performed at the central computer/database 140 on/by
manipulation device 140, it is preferred that post-initiation
changes be effected only at or by the individual machines 10.
[0279] With regard to the various optimization options, process
control parameters may be derived for a product-based optimization.
More particularly, the computer/database assembly 140 and
specifically the manipulation device 144 derives process control
parameters for achieving a predetermined yield of blood components
through a maximization of at least one process parameter as will be
discussed below in relation to the optimization models 152 (FIG.
9B), and 172 (FIG. 9C), for example, as noted above, in the United
States a single platelet product (SPP) is 3.times.1 011 platelets
and a double platelet product (DPP) is 6.times.1 011 platelets.
Consequently, the manipulation device 144 may be configured to
provide a number of product-based optimizations such as SPP and
DPP. Although the exact values for a current U.S. SPP and DPP could
be configured into the manipulation device 144, in order to
increase the probability that the actual yield will equal or exceed
the yield requirements for a current U.S. SPP or a DPP, the site
may configure a SPP to be 3.5.times.1 011 platelets and a DPP to be
7.0.times.1011 platelets (e.g., to effectively provide a given
confidence level over the minimum that the specified yield will
actually be met).
[0280] The manipulation device 144 may also be configured to
provide a time-based optimization. That is, for a given amount of
time for which a donor is available, the manipulation device 144
will derive those process parameters that allow for the collection
of a "maximum" amount of platelets in this time period in relation
to a maximization of at least one of the process control
parameters.
[0281] Once the optimization is complete, the values for the
various process control parameters generated thereby, as well any
ancillary/previously specified values, are downloaded to the
internal control of the blood collection device 18 such that the
collection procedure may be initiated or reinitiated (downstream
optimization) as the case may be in accordance with these values.
Once the procedure is completed, certain data is transferable
(electronically through the communication subsystem 146 or
otherwise as noted, e.g., floppy disk) back to the manipulation
device 144 and/or the central memory/database and/or the central
input station 148 for further use with regard to the particular
donor. In addition, this information as well as the initial input
may be used to generate various types of reports, which may further
assist in the management of the blood bank/center (e.g., individual
run, donor/patient, summary reports, etc.). That is, this
information may be used in the derivation of subsequent procedure
orders for the particular donor or even for improved efficiency for
entire pool of donors. For instance, in the event that a certain AC
infusion rate was used in the collection procedure which had
certain effects on this particular donor, this may be recorded in
the central memory/database 142 such that a lower AC infusion rate
would be suggested/required for subsequent donations by this donor
and perhaps also for the entire pool.
[0282] One model which may be incorporated into the manipulation
device 144 is illustrated in FIG. 9B and will be described with
regard to platelet collections in accordance with the dual needle
configuration of FIG. 7A, although the device 144 may be used with
a variety of other collection procedures and including the single
needle configuration of FIG. 7B, as well as with various other
blood components. Initially, it should be noted that all references
in FIG. 9B to "derivations" are actually provided by the prediction
model discussed above such that there is either an appropriate
communication interface between the prediction model and
manipulation device 144 or the manipulation device 144 actually
includes the prediction model disposed thereon or therein.
Moreover, as noted the prediction model described here is specific
to the blood component collection machine 18 and to platelet
collections. Therefore, if other machines are used, the associated
prediction model would also likely change as noted. Moreover, the
associated prediction model may also vary in the case where
different blood components such as red blood cells are to be
collected.
[0283] The optimizer model 152 of FIG. 9B may be used for both
product-based and time-based optimizations. Initially, the
optimizer model 152 will be described with regard to a
product-based optimization. That is, the fundamental premise of the
optimization is to achieve a predetermined platelet (or other blood
component type) yield (or within a yield range), preferably in the
minimum amount of time.
[0284] The optimizer model 152 of FIG. 9B is comprised of four
iterative loops. Generally, the first loop 156 is a derivation of
an inlet flow (Q.sub.IN) associated with a specified AC infusion
rate (I.sub.SPEC) which is typically set at a maximum value for
purposes of the present invention and which is entered at the input
station 154. This derivation is thereafter performed by the
processing station 158 and includes the solution of Eqs. 4, 8,14,
and 16 and/or equations ancillary thereto by the prediction model
as discussed above.
[0285] There are of course various convergence criterion/criteria,
which may be incorporated into the first loop 156. For instance,
convergence may be based upon the current inlet flow (Q.sub.IN-C)
in the first loop 156 through use of a binary search technique. In
this case, in solving the noted equations at the processing station
158 certain parameters remain fixed in the iterative derivation of
the inlet flow (Q.sub.IN) that achieves the specified AC infusion
rate (I.sub.SPEC) and these parameters are also specified at input
station 154. These include the total blood volume (V.sub.B) which
can be calculated using Eq. 10 since the donor's height, weight,
and gender are entered at the central input station 148, and the AC
ratio (R), which can be calculated using Eq. 9 since the donor's
hematocrit (H) has been determined, or may be specified at some
value. Moreover, the total procedure time (t.sub.P) remains fixed
in each iterative derivation of the inlet flow (Q.sub.IN)
associated with the specified AC infusion rate (I.sub.SPEC) in the
first loop 156. However, since the total procedure time (t.sub.P)
is not known in the case of a product-based optimization and thus
cannot be specified at the input station 154, a current total
procedure time (t.sub.P-C) initially will be assumed (e.g., this
assumption is configured in the optimizer model 152 and since a
range of total procedure times is provided in the prediction model
20 as noted above, the mean total procedure time (t.sub.P) is
typically configured into this portion of the optimizer model 152
as the initial current total procedure time (t.sub.P-C)). The
"current" designation is used for the total procedure time in this
case since the optimizer model 152 provides for an adjustment of
the total procedure time after each iterative determination of the
inlet flow (Q.sub.IN) which provides the specified AC infusion rate
(I.sub.SPEC) in the second loop 160 in order to achieve the desired
yield (Y) if required in the case of a product-based optimization
as will be discussed in more detail below.
[0286] Generally, the inlet flow-based binary search technique
convergence may be provided by assuming a current value for the
inlet flow (Q.sub.IN-C), calculating a current plasma collect
factor (P.sub.C) using the current total procedure time
(t.sub.P-C), calculating a current AC infusion rate (I.sub.C) using
the current inlet flow (Q.sub.IN-C) and current plasma collect
factor (P.sub.C), and adjusting the current inlet flow (Q.sub.IN-C)
(at the parameter update in the first loop 156) in accordance with
the selected binary search technique until there is a predetermined
convergence between the two most recent values for the current
inlet flow (Q.sub.IN-C) (i.e., wherein the difference between the
two most recent values of Q.sub.IN-C is less than some
predetermined amount which means that the convergence criterion is
met). In the case of a binary search technique, there will always
be convergence (i.e., the convergence criterion will always be met)
such that the optimizer model 152 will always exit the first loop
156 and enter the second loop 160.
[0287] As an alternative to the noted inlet flow-based convergence
criterion/criteria and the noted binary search technique, another
possibility is to base convergence on the specified AC infusion
rate (I.sub.SPEC) and use an iterative derivation to determine the
desired inlet flow (Q.sub.IN). In this case, the first loop 156 is
used to once again iteratively derive the inlet flow (Q.sub.IN),
which provides the specified AC infusion rate (I.sub.SPEC) at the
processing station 158 from certain specified parameters. That is,
the first loop 156 is still a maximization of the inlet flow
(Q.sub.IN) based upon the specified AC infusion rate (I.sub.SPEC),
which should be associated with the donor 14. This is again
primarily through the solution of Eqs. 4, 8, 14, and 16 and/or
equations ancillary thereto by the prediction model discussed
above.
[0288] For purposes of solving the above-identified equations in
relation to the infusion rate-based convergence criterion, certain
parameters remain fixed in the iterative derivation of the inlet
flow (Q.sub.IN), which achieves the specified AC infusion rate
(I.sub.SPEC) in the first loop 156 and these parameters are also
specified at the input station 154. These include the specified AC
infusion rate (I.sub.SPEC), which is known and which is typically a
maximum value for the donor 14, the total blood volume (V.sub.B)
which can be calculated using Eq. 10 since the donor's 14 height,
weight, and gender are entered in the central input station 148 or
downloaded from a disparate information database, and the AC ratio
(R) which can be calculated using Eq. 9 since the donor's 14
hematocrit (H) has been determined and input in the central input
station 148 or otherwise downloaded, or may be entered as modified
input data. Moreover, the total procedure time (t.sub.P) remains
fixed in each iterative derivation of the inlet flow (Q.sub.IN)
associated with the specified AC infusion rate (I.sub.SPEC).
However, once again the total procedure time (t.sub.P) is not known
in the case of a product-based optimization and thus cannot be
specified at the input station 154. Therefore, a current total
procedure time (t.sub.P-C) initially will be assumed (e.g., this
assumption is configured in the optimizer model 152, and since a
range of total procedure times is provided in the prediction model
as noted above, the mean total procedure time (t.sub.P) is
typically configured into the first loop 156 of the optimizer model
152). The "current" designation for the total procedure time is
used for the above-identified reasons relating to the adjustment of
the total procedure time in the second loop 160 if required to
attain the desired yield (Y).
[0289] The solution of Eqs. 4, 8, 14, and 16 also requires that
certain values be assumed for certain of the remaining parameters
with still other parameters being derived from this assumption. In
this case, an iterative procedure is used and updated/current
values are used in the next iterative calculation(s). All
parameters that change on each iteration of the first loop 156 are
identified herein with a "c" subscript to designate that the most
current value is to be used. Although the derivation of that inlet
flow (Q.sub.IN) which provides the specified AC infusion rate
(I.sub.SPEC) may be accomplished in a variety of manners via Eqs.
4, 8, 14, and 16, one way is to assume a current value for the
plasma collect factor (P.sub.C), then calculate the current inlet
flow (Q.sub.IN-C) using the specified AC infusion rate
(I.sub.SPEC), then calculate the current yield (Y.sub.C), then
calculate the current plasma collection factor (P.sub.C) using the
current yield (Y.sub.C), and repeat this procedure with the current
values until there has been acceptable convergence on the current
inlet flow (Q.sub.IN-C) in relation to the specified AC infusion
rate (I.sub.SPEC) (e.g., when the particular convergence criteria
are met). When there is acceptable infusion rate-based convergence,
the optimizer model 152 exits the first loop 156 and enters the
second loop 160. In order to offer protection for cases when there
is no such convergence, a maximum number of iterations for the
first loop 156 may be specified (not shown).
[0290] The second loop 160 of the optimizer model 152 is a total
procedure time (t.sub.P) iteration. That is, the second loop 160 is
an iterative adjustment of the current total procedure time
(t.sub.P-C). Initially, in the second loop 160 and in the case of a
product-based optimization the model 152 will never exit at the
first comparator 162 since a total procedure time (t.sub.P) is not
specified at the input station 154. Consequently, the optimizer
model 152 proceeds to the second comparator 166 where convergence
criteria (i.e., more than one check) is made. One convergence
criterion that is checked at the second comparator 166 is whether
the current yield (Y.sub.C) is greater than or equal to the desired
and specified yield (Y). In this case, the current yield (Y.sub.C)
may be calculated based upon the values specified at the input
station 158, values derived at the processing station 158, and the
current total procedure time (t.sub.P-C) for comparison with the
desired and specified yield (Y) (in some cases, this current yield
calculation (Y.sub.C) may have been performed in the first loop 156
and need not be repeated in the second loop 160). If the yield
convergence criterion is met, the model 152 exits the second loop
160 and actually exits all the way through to the exit 151, as will
be discussed below. In this case, the specified/derived values are
"optimal" and the collection procedure could be performed on the
device 18 using the noted values for the various control
parameters.
[0291] In the event that the yield-based criterion is not met at
second comparator 166, the second comparator 166 looks to a total
procedure time-based convergence criterion which may be similar to
that discussed above with regard to the inlet flow-based criterion
(e.g., using a binary search technique with the convergence
criterion then being a predetermined difference between the two
most current values of the total procedure time (t.sub.P-C)). On
the first time through the second loop 160 after the noted
yield-based convergence criterion has failed and the total
procedure time convergence criterion has failed, the current total
procedure time (t.sub.P-C) is adjusted and the model 152 returns to
the first loop 156. That is, each time that the current total
procedure time (t.sub.P-C) is adjusted in the second loop 160, the
entirety of the first loop 152 is repeated (i.e., a new inlet flow
(Q.sub.IN) associated with the specified AC infusion rate
(I.sub.SPEC) is derived using the current total procedure time
(t.sub.P-C) provided by the adjustment in the second loop 160).
Other convergence criterion/criteria could be used in the second
loop 160, such as specifying a maximum number of iterations to be
performed by the second loop 160.
[0292] In the event that the yield-based convergence criterion is
not met on the second loop 160 and the total procedure time-based
convergence criterion is met at the second comparator 166 in the
second loop 160, the optimizer model 152 exits the second loop 160
and enters the third loop 164. The third loop 164 is an iterative
adjustment of the AC ratio (R). However, the model 152 initially
enters the third comparator 169 where convergence criteria (i.e.,
more than one) are checked. One convergence criterion is again the
above-noted yield-based convergence criterion. If this yield-based
convergence criterion is again not met, an AC ratio-based
convergence criterion is checked at the third comparator 169. This
may be similar to the inlet flow-based criterion discussed above
(e.g., using a binary search technique with the convergence
criterion being the two most current values of the AC ratio). On
the first time through the third loop 164 after the yield-based
criterion has failed and the AC ratio-based convergence criterion
has failed, the AC ratio is adjusted and the optimizer model 152
returns to the first loop 152. That is, each time that the AC ratio
(R) is adjusted in the third loop 164, the entirety of the first
and second loops 156, 160, respectively, is repeated. Other
convergence criteria could be used in the third loop 164, such as
specifying a maximum number of iterations of the third loop
164.
[0293] In the event that the yield-based convergence criterion is
not met in the second or third loops 160,164, respectively, and the
second and third comparator 166, 169, respectively, and the AC
ratio-based convergence criterion is met at the third comparator
169 in the third loop 164, the optimizer model 152 exits the third
loop 164 and enters the fourth loop 168. The fourth loop 168 is an
iterative adjustment of the specified AC infusion rate
(I.sub.SPEC). However, the optimizer model 152 initially enters the
fourth comparator 170 where convergence criteria (i.e., more than
one) are checked. One convergence criterion is the noted
yield-based convergence criterion. If the noted yield-based
convergence criterion is not met at the fourth comparator 170, an
AC infusion rate-based criterion is checked at the fourth
comparator 170. This may be similar to the inlet-flow based
criterion discussed above (e.g., using a binary search technique
with the convergence criterion being the two most current values of
the AC infusion rate). On the first time through the fourth loop
168 after the yield-based criterion has failed and the AC infusion
rate-based convergence criterion has failed, the AC infusion rate
is adjusted and the model 152 returns to the first loop 152. That
is, each time that the specified AC infusion rate (I.sub.SPEC) is
adjusted, the entirety of the first, second and third loops 156,
160, 164, respectively, is repeated (with the AC ratio set back to
its initial value as entered at the input station 154 on each
iteration of the fourth loop 168). Other convergence
criterion/criteria could be used in the fourth loop 168, such as
specifying a maximum number of iterations of the fourth loop 168.
In cases where the specified AC infusion rate (I.sub.SPEC) is
actually the maximum AC infusion rate, typically the fourth loop
168 will execute only a single time with a one-time increase in the
AC infusion rate of, for instance, 20% (e.g., may be
site-configured).
[0294] In the foregoing loops where a yield-based convergence
criteria are identified, when the criteria are met the optimizer
model 152 exits to exit 151 and the specified/derived (i.e.,
current) values for the various process control parameters may be
provided to the device 18 for performing the collection procedure.
However, there may be cases where no optimization occurs, such as
when the optimizer model 152 exits to the exit 151 based upon the
AC infusion rate based convergence criterion being met.
[0295] The optimizer model 152 may also be used for a time
optimization. That is, the optimizer model will derive optimal
process parameters for a predetermined total procedure time
(t.sub.P) through maximization of at least one of the process
parameters in order to maximize the platelet collection (or for
other blood component types). In this case, the optimizer model 152
only executes the first loop 156 to derive the inlet flow
(Q.sub.IN) associated with a specified AC infusion rate
(I.sub.SPEC) (typically a maximum value) using the input total
procedure time (t.sub.P) in this iterative derivation instead of
the assumed total procedure time (t.sub.P) referenced above. Once
there is acceptable convergence as defined above in the
product-based optimization such that model 152 exits the first loop
156, the current yield (Y.sub.C) may be calculated in the first
loop 156 (but again may already have been calculated in the first
loop 156 at the processing station 158 such that no further
calculation is required) and the convergence criterion will be met
at the first comparator 162 when entering the second loop 160
(i.e., in a time-based optimization when a total procedure time is
specified at the input station 154, the model 152 will exit when
entering the second loop 158). As a result, the inlet flow
(Q.sub.IN) and AC infusion rate (I) will be optimal and the
collection procedure may be performed with such values.
[0296] Another optimization model is presented in FIG. 9C and may
be used for both product-based and time-based optimizations. As in
the case of the optimizer model 152, the optimizer model 172 may
interface with the prediction model or actually integrally
incorporate the prediction model, and thus reference to Eqs. 1-22
will be further made herein. Generally, the optimizer model 172 is
based upon the principle that optimization occurs when an optimal
inlet flow (Q.sub.L) associated with an optimum system collection
efficiency is used in the derivation of various process control
parameters. Referring to FIG. 10, a representative inlet flow
(Q.sub.IN)/yield (Y) curve is presented to show the optimal inlet
flow (Q.sub.L) associated with the maximum yield (Y.sub.MAX). This
optimal inlet flow (Q.sub.L) is mathematically expressed by Eq. 23,
presented below, which results from differentiating Eq. 4 of the
prediction model with regard to the inlet flow (Q.sub.IN). As can
be appreciated, where different algorithms are used in the
associated prediction model (whether based upon collection of blood
components other than platelets, different collection apparatus, or
alternative derivations of the various parameters with the same
collection procedure and apparatus), the optimal inlet flow may be
mathematically expressed in a different manner.
Q.sub.L=(C1/2C.sub.2)e.sup.-9.91(1-1/R)H-C.sub.3 (Eq. 23).
C.sub.3=1/(2(tp/K7-1/K9))Q.sub.0.gtoreq.45 for Dual Needle ("DN")
(Eq. 24) Q.sub.0.gtoreq.20 for Single Needle ("SN") C.sub.3=0
Q.sub.0.ltoreq.45 for DN (Eq. 25) Q.sub.0.ltoreq.20 for SN
K.sub.7=500(DN)K.sub.9=45(DN) (Eq. 26)
K.sub.7=215(SN)K.sub.9=20(SN) C.sub.1=0.803(SN, DN without
stepdown) (Eq. 27) C.sub.1=0.840(DN with stepdown)
C.sub.2=4.08.times.10.sup.-5(DN) (Eq. 28)
C.sub.2=8.54.times.10.sup.-5(SN)
[0297] Based upon the foregoing, the optimal inlet flow (Q.sub.L)
is really "optimal" in terms of the collection apparatus.
[0298] Referring again to FIG. 9C, the optimizer model 172 will
initially be described with regard to a product-based optimization
wherein the desired yield (Y) is specified at input station 184.
Generally, the inlet flow (Q.sub.IN) associated with a specified AC
infusion rate (I.sub.SPEC) (typically the maximum AC infusion rate
and also specified at input station 184) is iteratively derived
from certain other specified parameters. This inlet flow
calculation, particularly when the maximum AC infusion rate
(I.sub.MAX) and maximum AC ratio (R.sub.MAX) are specified, the
inlet flow (Q.sub.IN) is optimal based on the physiological
considerations of the donor 14. This is primarily through the
solution of Eqs. 4, 8, 14, and 16 and/or equations ancillary
thereto by the prediction model discussed above. For purposes of
solving these equations certain parameters remain fixed in the
iterative derivation of the inlet flow (Q.sub.IN), which achieves
the specified AC infusion rate (I.sub.SPEC) and these parameters
are also specified at input station 184. These include the total
blood volume (V.sub.B) which can be calculated using Eq. 10 since
the donor's height, weight, and gender are entered in the central
input station 148, and the AC ratio (R), which can be calculated
using Eq. 9 since the donor's hematocrit (H) has been determined,
or may be specified at some maximum value. Moreover, the total
procedure time (t.sub.P) remains fixed in each iterative derivation
of the inlet flow (Q.sub.IN) associated with the specified AC
infusion rate (I.sub.SPEC). However, since the total procedure time
(t.sub.P) is not known in the case of a product-based optimization
and thus cannot be specified at the input station 184, a current
total procedure time (t.sub.P-C) initially will be assumed (e.g.,
this assumption is configured in the optimizer model 172 and since
a range of total procedure times is provided in the prediction
model as noted above, the mean total procedure time (t.sub.P) is
typically configured into this portion of the optimizer model 172
as the initial current total procedure time (t.sub.P-C)). The
"current" designation is used for the total procedure time in this
case since the optimizer model 172 provides for an adjustment of
the total procedure time after each iterative determination of the
inlet flow (Q.sub.IN) which provides the specified AC infusion rate
(I.sub.SPEC) in order to achieve the desired yield (Y) if required
in the case of a product-based optimization as will be discussed in
more detail below.
[0299] The solution of Eqs. 4, 8, 14, and 16 also requires that
certain values initially be assumed for certain of the remaining
parameters. In this case, an iterative procedure is used in the
solution of the yield equation (Eq. 4) (and including equations
ancillary thereto as noted above) and updated values are used in
the next iterative calculation(s) at the processing station 188.
Although the derivation of that inlet flow (Q.sub.IN) which
provides the specified (typically maximum) AC infusion rate
(I.sub.SPEC) may be accomplished in a variety of manners via Eqs.
4, 8, 14, and 16, one way is to assume a current value for the
plasma collect factor (P), then calculate the current inlet flow
(Q.sub.IN-C) using the specified AC infusion rate (I.sub.SPEC),
then calculate the current yield (Y.sub.C), then calculate the
current plasma collection factor (P.sub.C) using the current yield
(Y.sub.C), and repeat the foregoing with the updated parameters,
all within the processing station 188, until there has been
acceptable convergence on the current inlet flow (Q.sub.IN-C) in
relation to the specified AC infusion rate (I.sub.SPEC).
[0300] In addition to the calculation of the current inlet flow
(Q.sub.IN-C) associated with the specified AC infusion rate
(I.sub.SPEC), the above-discussed optimal inlet flow (Q.sub.L) is
calculated at processing station 192. Consequently, a comparison
can be made between the current inlet flow (Q.sub.IN-C), which was
derived in the above-described manner and the optimal inlet flow
(Q.sub.L) at the first comparator 176. If the current inlet flow
(Q.sub.IN-C) is less than the optimal inlet flow (Q.sub.L) at the
first comparator 176, the specified values for the various
parameters associated with the inlet flow Q.sub.IN are "optimum",
namely the AC ratio (R) and the AC infusion rate (I) specified at
the input station 184. Thereafter, the current yield (Y.sub.C)
(which was calculated in the derivation of the current inlet flow
(Q.sub.IN-C) associated with the specified AC infusion rate
(I.sub.SPEC) at the processing station 188) is compared with the
input yield (Y) at second comparator 180. In the event that there
has been acceptable convergence between these yield values, the
current total procedure time (t.sub.P-C) is also "optimal".
However, in the event that there has not been acceptable
convergence between these yield values, the current total procedure
time (t.sub.P-C) is adjusted at adjusting station 196 and the
foregoing iterative derivation of the current inlet flow
(Q.sub.IN-C) associated with the specified AC infusion rate
(I.sub.SPEC) is repeated until such convergence is achieved (i.e.,
using the initially specified AC infusion rate (I.sub.SPEC) and the
now adjusted current total procedure time (t.sub.P-C), a new
current inlet flow (Q.sub.IN-C) is iteratively derived in the
above-described manner).
[0301] Referring back to the first comparator 176, if the current
inlet flow (Q.sub.IN-C) associated with the specified AC infusion
rate (I.sub.SPEC) derived at processing station 188 is greater than
the optimal inlet flow (Q.sub.L), a current AC infusion rate
(I.sub.C) associated with this particular inlet flow (Q.sub.L) is
iteratively derived at the processing station 188 generally in the
above-described manner (i.e., the initially specified AC infusion
rate (I.sub.SPEC) is disregarded in this derivation and a current
AC infusion rate (I.sub.C) is iteratively derived to coincide with
the inlet flow (Q.sub.L)). In this case, the current inlet flow
(Q.sub.IN-C) will always be equal to the optimal inlet flow
(Q.sub.L) at the first comparator 176 and the optimizer model 172
thereafter proceeds to the second comparator 180 for the yield
comparison in accordance with the above-described procedure.
[0302] The optimizer model 176 may also be used for a time-based
optimization. In this case, the total procedure time (t.sub.P) is
specified at the input station 184 as a specified total procedure
time (t.sub.P-SPEC) and thus is not assumed as in the product-based
optimization. The optimizer model 172 thereafter proceeds in the
same manner discussed above with regard to the product-based
optimization except at the second comparator 180. Since no yield
was input there is no yield comparison made at the second
comparator 180. Instead a total procedure time comparison is made
at the second comparator 180. Since the current total procedure
time (t.sub.P-C) was set equal to the specified total procedure
time (t.sub.P-SPEC) prior to the model 172 proceeding to the
processing station 188 in this time-based optimization, the model
172 will exit each time at the second comparator for a time-based
optimization.
[0303] In addition to the above-described product-based and
time-based optimizations, the principles of the present invention
may be extended to other applications relating to enhancing blood
component system management. For instance, an optimization in
accordance with principles of the present invention may be extended
to encompass donor management issues. In one such case, another
"optimization" associated with the blood component collection
process would be to collect blood components as dictated by
existing inventory (i.e., use optimization as an inventory
control). That is, information relating to the inventory of the
various types of blood components in the blood bank or the demand
for one or more blood component types could be maintained such that
specific collection procedures could be selected to accommodate for
a low supply of a given blood component type or a high demand for
such blood component type. More specifically, in the event that the
supply of red blood cells was low and/or the demand for red blood
cells was high, or anticipated to be so in the near future, prompts
could be provided to operators that red blood cells should be
selected for collection if possible from donors during a given time
period. Relatedly, the optimization principles of the present
invention would be applicable to maintaining data on blood
component collections from a given donor such that a determination
could be made as to what type or types of blood components from the
particular donor provided the maximum yield in the collection
procedure. That is, information could be collected and maintained
from prior blood component donations such that a determination
could be made for a specific donor as to which type or types of
blood components the donor has had a propensity to produce maximum
yields therefor.
[0304] Notwithstanding the foregoing description of the present
invention in relation to an on-line blood component collection
process, those skilled in the art will appreciate that the source
of blood may be provided to the blood component collection device
from an appropriate blood container (not shown) interconnected with
the blood component collection device 18 versus receiving such
directly from a human donor. Moreover, the blood of course may be
provided from alternative sources such as animals. Furthermore, as
illustrated in FIG. 7B the described component (platelet, RBC,
plasma, inter alia) harvesting procedure may be performed utilizing
a single needle configuration. In addition, the present invention
is applicable to the collection of other types of blood components
such as red blood cells, stem cells, white blood cells, and/or
plasma, and is further applicable to the simultaneous collection of
more than one blood component type. In the case of red blood cell
collection and optimization in accordance with principles of the
present invention, the donor's blood type should be known and used
in various algorithms. Moreover, the present invention is not
limited to the source being whole blood. That is, the principles of
the present invention may be applicable to removal of a component
from any composite liquid, i.e. any liquid containing separable
components (preferably separable using mechanical procedures.
