CROSS REFERENCE TO RELATED APPLICATIONS
[0001] This application claims the benefit of priority under 35
U.S.C. .sctn. 119 of German Patent Application DE 10 2008 034 243.3
filed Jul. 23, 2008, the entire contents of which are incorporated
herein by reference.
FIELD OF THE INVENTION
[0002] The present invention pertains to a device for use with a
treatment device for treating a patient pertains as well as to a
workstation with a plurality of treating devices and/or monitoring
devices for the treatment and/or monitoring of the patient.
BACKGROUND OF THE INVENTION
[0003] Modern workstations for the treatment of patients, for
example, in the area of anesthesia, intensive care or neonatology,
are known from practice. These workstations are characterized by
high requirements imposed on the integration of devices used
simultaneously or with one another. Thus, a number of devices, such
as patient monitors, drug pumps, documentation systems and others
are regularly connected functionally into one integrated
workstation.
[0004] The treatment carried out with the workstation may comprise
a plurality of phases, which follow each other and can often be
clearly distinguished from one another. Based on the example of
anesthesia, these phases may comprise induction of anesthesia,
maintenance of anesthesia and emergence from anesthesia. These
phases can, furthermore, be divided into detailed process steps.
Additional activities, which pertain, for example, to the transfer
of the patient from the induction room into the operating room, use
of a heart-lung machine, taking of x-rays and the like, can be
optionally added to the individual phases.
[0005] When passing over from a first phase of the treatment to a
second phase, it is necessary, as a rule, to manually adapt a
number of settings at the workstation or at the treatment devices
comprised by said workstation to phase-typical or phase-dependent
boundary conditions. Based on the example of anesthesia,
interactions, such as changes in therapy settings (gas
concentration, ventilation parameters), alarm settings (setting of
alarm limits, activation/deactivation of alarms) as well as
adjustments to the control surface, may be necessary at the time of
such a phase transition. These actions, which are repeated during
each treatment or anesthesia, must be carried out separately at
individual components and devices comprised by the workstation.
[0006] The adjustments of the above-mentioned settings regularly
represent a great effort for the person in charge of the treatment
of the patient (the attending physician or nurse). It can therefore
be observed in practice that regularly only the most needed
adjustments, e.g., the control of the depth of anesthesia by
setting the gaseous anesthetic concentration, are carried out at
the time of transition from one phase of treatment to the next,
especially under time pressure and stress. Other adjustments, for
example, the adjustment of the alarm settings, are often neglected
because of the complicated and uncomfortable operation. This may
lead to undesired behavior of the device. One example of this is
false alarms caused by suboptimal settings. However, dangerous
situations may occur as well, because important interactions, such
as reactivation of the alarms of hemodynamic monitoring after the
termination of the operation of the heart-lung machine, were
forgotten or were not executed for other reasons. Thus, the
insufficient technical support does not prevent erroneous human
behavior, which represents a considerable safety risk. Furthermore,
the operation of the therapeutic workstation differs from one user
to the next while the activities are comparable per se. This makes
it difficult to improve quality by means of standardized
procedures.
SUMMARY OF THE INVENTION
[0007] The object of the present invention is therefore to provide
an improved device for supporting the user in charge of treating
the patient.
[0008] According to the invention, a device is provided for use
with a treatment device for treating a patient. The device
comprises a detection means for detecting at least one phase of
treatment and/or a transition of the patient's treatment from a
first phase of treatment to a second phase of treatment and a
signal means for sending at least one signal related to the
detected phase of treatment and/or a signal when the transition is
detected.
[0009] A device is provided according to the present invention,
which has at least one detection means, by means of which a
transition of the treatment of the patient from a first phase of
treatment to a second phase of treatment, from a second phase of
treatment to a third, from a third phase of treatment to a fourth,
etc., can be detected. Moreover, a phase of treatment may also be
able to be detected by means of the detection means. It is thus
possible to detect or identify the first, present phase as such
independently from a phase transition. Means known to the person
skilled in the art, such as measuring means or patient monitors,
may be used for this. Inputs by the user and combined,
semiautomatic detections are likewise covered by the present
invention.
[0010] A treatment phase is defined according to the present
invention as a phase such as the phases of induction, anesthesia
maintenance and wake-up phase mentioned above based on the example
of anesthesia. Phases may comprise, according to the invention, a
process or a plurality of processes as well as subphases. A phase
is characterized by one parameter or a plurality of parameters. The
transition from a first phase of treatment to a second one may
therefore comprise a change in one or more parameters. A phase
transition shall not be defined according to the present invention
as being limited to intermittent transitions. A phase transition
may rather also take place continuously, steadily, with a range of
overlap or the like. It may therefore likewise be possible that
both features of the first phase and features of the second phase
can be observed simultaneously along with each other at defined
times during the phase transition.
[0011] The device according to the present invention has,
furthermore, at least one signal means for sending at least one
signal as a consequence of the detection of a transition. A signal
is defined according to the present invention quite generally as
communicated information: The signal may indicate, for example,
that a phase transition has taken place, is taking place or will
take place (announcement). Besides or as an alternative to the
communication function, the signal may also have a regulating or
controlling action: Thus, the signal can inform the treating person
of a phase transition in case of a suitable display (optical,
acoustic, etc.). However, the signal may also act on the treatment
device in such a way as to bring about, triggered by the reception
of the signal, changes in treatment parameters and/or treatment
processes. The signal, which is sent when the transition is
detected, may precede the point in time at which the transition
takes place, coincide with it or follow it in time. However, the
signal may also pertain to a currently present phase only, i.e., it
may be sent separated from a phase transition.
[0012] A phase or a phase transition can be detected according to
the present invention by means of the detection means, for example,
on the basis of a manual identification, e.g., by inputting via
user interaction elements by the user. However, semiautomatic
detection in the sense of identification, for example, by the
analysis of information of the device sensors, of patient
monitoring, of time measurement and the like is also defined
according to the present invention as "detection," and so is an
acknowledgement of a changeover from one phase to another, which is
proposed by the user. Furthermore, purely automatic detection or
identification of a phase or of a phase transition is also possible
by means of the detection means. For example, the first-time
recognition by the machine of an administration of anesthetics or
the like can thus represent a phase transition. The sending of the
signal may lead to automatic activation of the relevant alarm for
the drug concentration.
[0013] Thus, a device with a display means for displaying the phase
of treatment in which the patient is at a defined point in time is
proposed in a preferred embodiment. This point in time may already
be in the past, or it may pertain to the current point in time of
polling or to a point in time in the future. The history of the
treatment as well as expected treatment events such as phase
transitions can thus be displayed by means of the display means.
The knowledge of the treatment phase in which the patient is at the
given point in time (displayed, for example, by the display means)
makes it possible for the treating person to make a comparatively
simple classification or rating of parameter values. Thus, a
defined parameter value may be unusual for a first phase of
treatment but usual for a second phase of treatment. If the phase
of treatment of the patient during which the parameter had a
defined parameter value is displayed to the treating person,
deviations of the parameter can be determined more easily and
countermeasures can possibly be initiated sooner.
[0014] In another preferred embodiment, the device according to the
present invention has a selection means for selecting future
treatment phases. The definition of "selection" also includes
dropping, terminating, confirming and the like. The possible phases
of treatment may be limited only to the phases that are
meaningfully considered in the phase as the next phase based on a
current phase. A selection of decisions can thus be offered to the
treating person, in which every one of the options to be selected
is also meaningful and desirable at the moment of selection. The
mental selection of phases that are logically not possible or are
less desirable in the particular case or at the particular moment
is thus simplified. Nonsensical options can already be recognized
as such at the device and cannot be offered in the first phase at
all. Whether the selection takes place for the point in time of the
selection operation or for a point in time that is in the future,
especially the near future in time, makes no difference according
to the present invention. The selection by means of the selection
means may take place, for example, via one or more user interaction
elements.
[0015] In yet another preferred embodiment according to the present
invention, the device has a display means for displaying the
actions associated with a phase or with a phase transition. A
review of all the processes and operations that are relevant or
necessary during the phase or at the time of the change from one
phase to another may now be displayed to the user. This is
especially helpful for those whose adjustment must not be
overlooked and/or for those that are executed automatically by the
treating person during the phase transition. The treating person is
thus always in the picture about which changes are, in particular,
associated or must be associated with a transition of the treatment
from a first phase of treatment to a second one.
[0016] As was already provided in another preferred embodiment,
individual actions or adjustment of the parameters thereof can be
dropped by means of an input means. Furthermore, the phase
transition can be confirmed or terminated.
[0017] In yet another preferred embodiment according to the present
invention, the device has a data bank means for storing work flows,
e.g., SOPs (Standard Operating Procedures) in a comprehensive
manner. All the possibly parametrized actions and SOPs, which are
carried out at the time of a phase transition or a transition from
one state to another, can be defined in such a work flow data bank.
For example, all ECG (electrocardiogram) alarms can be switched off
or suspended following activation of the heart-lung machine. The
data bank may contain meaningful presettings provided by the
manufacturer, which can counteract erroneous setting and contribute
to increased safety. The data bank may be designed such that it can
be adjusted by the user to any desired standards, including local
ones (SOPs) and norms with suitable tools. Whether or not a
confirmation by the user is necessary before the action is carried
out may possibly also be stored in the data bank. For example, it
would be possible to specify that a message is sent to the
operating room cleaning team without checking at the time of
transition into the phase of emergence from an anesthesia. Besides
the definition of a standard setting, the data bank may also have
sets of settings, which are specific of certain interventions.
[0018] In yet another preferred embodiment, the device according to
the present invention has, furthermore, a control means for
controlling the work flow. Inputs entered via the selection means,
the input means and the like as well as the detection means can be
checked for consistency by means of such a control means.
Furthermore, especially if the nature of the intervention or
treatment can be polled from the surgery planning or other IT
systems, the standard settings can be replaced with specific
settings from the process data bank. Furthermore, the corresponding
actions can be polled from the work flow data bank in case of phase
transitions or transitions from one state to another and the
actions stored may possibly be presented to the user for
confirmation via the operating and display unit. The actions
confirmed by the user can be communicated in suitable formats to
receivers, for example, the internal device control or external IT
systems.
[0019] The advantages that can be obtained according to the present
invention comprise, among other things, optimal support of the
person treating the patient and a general improvement in operating
convenience.
[0020] Furthermore, the patient's safety is markedly increased
compared to the extent hitherto common in practice. Improved safety
of the patient and checking by the user, among other things, by the
acknowledgment mechanism described, can thus be guaranteed. The
number of human interactions necessary during a phase transition
can be limited to a minimum. Operating convenience is increased
while the probability of operating errors is minimized at the same
time.
[0021] Furthermore, a positive effect on quality and efficiency can
be achieved due to more standardized procedures (SOPs--Standard
Operating Procedures) by means of the technical support of the
treating person by the device according to the present invention.
The present invention advantageously contributes, furthermore, to
documentation, for example, in connection with surgical procedures,
because phase transitions are already detected by the device and
their occurrence only needs to be stored. This also applies to the
processes brought about by the signal sent or to transmitted
information. Furthermore, SOPs can be technically supported.
Standardization and hence quality assurance of anesthesia can
likewise be promoted. Higher-level work flows of the hospital can
be triggered or supported by connecting external IT systems. A work
flow data bank that can be freely configured offers the needed
flexibility to add, adjust or update standards. The workstation
documentation and especially the anesthesia documentation can be
automatically complemented with information on the phase
identification.
[0022] The present invention is also accomplished by a workstation,
especially an anesthesia workstation, with a plurality of treatment
devices and/or monitoring devices for treating and/or monitoring
the patient with the device features for treatment phase detection
and signaling. The workstation has at least one device according to
the present invention as described above. Since all the advantages
discussed above can be gained in full measure by means of the
workstation according to the present invention, reference is
expressly made here to the above discussion of these advantages to
avoid repetitions.
[0023] The above-described procedure can also be applied in this
form to other workstations, especially workstations used in
emergency medicine. It is advantageous in this connection if a
component of the integrated workstation ensures the needed
connectivity and a computing unit images the above-described
process logic.
[0024] It is advantageously possible in an intensive care
workstation to adjust the settings of the actuator mechanism and
alarm management as well as of the graphic user interface of the
patient monitor, respirator, thermotherapy device, syringe/infusion
pumps and hemofiltration apparatus during defined phases. These
phases, which are associated with treatment steps performed at the
patient, include, for example, basic nursing (washing,
positioning), physical therapy, endotracheal suction, taking of
blood, resuscitation, transport, etc.
[0025] What was said in connection with the intensive care
workstation in reference to the above-described invention applies
to the neonatological workstation. However, integration of
thermotherapy (incubators, heat radiators) and the work flows
associated therewith is of particular importance here.
[0026] The present invention will be explained in more detail below
on the basis of the drawings. The various features of novelty which
characterize the invention are pointed out with particularity in
the claims annexed to and forming a part of this disclosure. For a
better understanding of the invention, its operating advantages and
specific objects attained by its uses, reference is made to the
accompanying drawings and descriptive matter in which preferred
embodiments of the invention are illustrated.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0033] Referring to the drawings in particular, FIG. 1 shows an
example of an integrated workstation 1 for treating a patient from
anesthesia. The anesthesia apparatus 3 as the core of the
workstation 1 is technically linked with additional devices such as
a patient monitor 5, drug pumps 7, a documentation system 9, a
control interface 11 and other components.
[0034] FIG. 2 shows an example of consecutive phases of an
anesthesia with a phase transition each between them. The phases
"induction" 2, "maintenance" 4 and "emergence" 6 can be further
divided into more detailed process steps such as "premedication" 8,
"intubation" 10, "wash-in" 12, "instrumentalization" 16, "wash-out"
18 and "extubation" 20. They may optionally also be complemented
with processes such as transfer of the patient from one operating
room into another, the switching on of a heart-lung machine (HLM)
14, FIG. 3, and the like.
[0035] FIG. 3 shows an example of a "phase indicator and phase
transition" interface. User interaction elements for the transition
into another phase are displayed. Only logically possible phases,
such as "induction" 2, "maintenance" 4 and use of the heart-lung
machine 14 (HLM) and "emergence" 6, are displayed to the user for
selection.
[0036] FIG. 4 shows an example of a "confirmation of phase
transition", "maintenance" 4, "emergence" 6 control interface 11
with a sequential succession of the relevant phases during
anesthesia during a cardiac surgical intervention with the use of
the heart-lung machine HLM, which [interface] can be used during a
treatment according to the example shown in Table 1 with ten phase
transitions ("0" to "9," see tabular representation in Table 1).
The information that is displayed to the user during the particular
phase transition for confirmation (cf. FIG. 4) is found under
"therapy settings" and "alarm settings" in Table 1. Furthermore,
the particular adjustments that are performed at the user interface
are listed under "UI adjustments" (UI=User Interface). The
communication of confirmed phase transitions with external IT
systems for the purpose of documentation and process control is not
shown or indicated in Table 1.

[0037] A first phase transition is designated by "0" in Table 1.
The user now administers an "oxygen douche" (100% O.sub.2 with high
fresh gas flow) to the patient for the first time and administers
relaxing and sedating drugs in order to prepare the patient for
intubation.
[0038] An "intubation" phase transition designated by "1" is
confirmed by the user. He can very easily check the success of the
intubation by means of the automatically displayed capnogram
without being distracted by disturbing alarms; these are
automatically suppressed, as can be seen in the "alarm settings"
column.
[0039] The dialog for the wash-in is automatically offered to the
user after intubation during the phase transition designated by "2"
(capnogram analysis). Respiration and anesthesia with a gaseous
anesthetic is started after confirmation of the values proposed by
the treating person. Alarms that are no longer needed are in turn
switched off. If the expiratory target concentration in the
breathing gas is reached, the dialog for a transition "3" into the
phase of instrumentalization appears, during which all hemodynamic
alarms are in the automatic wake-up mode after confirmation by the
user.
[0040] If the induction measures are concluded, the user can change
over manually into anesthesia maintenance (transition "4") by
actuating the "maintenance" button. The patient is adequately
respirated and anesthetized and all alarms are activated now.
[0041] The HLM is used (transition "5") in the course of surgery.
The user actuates the "HLM" button for this purpose and confirms
the corresponding dialog. The alarms are set to the HLM mode in
order to avoid false alarms. Respiration and anesthesia are
likewise reduced, because these tasks are taken over by the
HLM.
[0042] If the output of the HLM is reduced in the further course,
this can be detected from pulses of the invasive pressure and
resumption of the ECG activity (transition "6"). This leads to
automatic display of the corresponding dialog; respiration,
dispensing of anesthetic and full alarm functionality are
reactivated.
[0043] After conclusion of the procedure (transition "7"), the user
can start the emergence from the anesthesia by actuating the
"wash-out" button--the gaseous anesthetics are washed out, oxygen
saturation is reached, and the alarm functionality is reduced.
[0044] If the patient is sufficiently alert (transition "8"), the
user can prepare the patient for the extubation by actuating the
"extubation" button. All alarms are deactivated for this.
[0045] The anesthesia is thus concluded and the apparatus can pass
over into the standby mode (transition "9").
[0046] FIG. 5 shows possible components of a device 13 according to
the present invention with a control means 15 for work flows, with
a detection means 17, with an input and display means 19, with a
data bank means 21 and with additional means. It is pointed out
that individual components may be provided in order to assume more
than only one function. For example, one means may send a signal
and also store same.
[0047] The control means 15 is connected via an apparatus control
22 to a data logging means 23, to a generator 24 for generating
control surfaces and to a signal means 25. Settings may be made via
a module 26. Furthermore, a surgery planning module 27 and a
surgery documentation module 28 are provided.
[0048] While specific embodiments of the invention have been shown
and described in detail to illustrate the application of the
principles of the invention, it will be understood that the
invention may be embodied otherwise without departing from such
principles.
