Description
[0001] This application claims the benefit of U.S. provisional
application Serial No. 60/202,283 filed May 5, 2000 and U.S.
provisional application Serial No. 60/229,136 filed Aug. 30, 2000,
both disclosures being expressly incorporated by reference
herein.
[0002] The invention relates to a computer system configured to be
used at the point of care by the caregiver in a hospital or other
health care facility in order to care for patients. The present
invention facilitates electronic data entry at the point of care,
provides automatic data capture, provides a computer screen with a
flow sheet sized proportion, provides access to information at the
point of care.
[0003] Providing a computer at the point of care provides access to
information from a laboratory, pharmacy, radiology, or other
locations away from the point of care where it is needed at the
point of care. The computer system of the present invention
includes both manual and automated patient data entry at the point
of care create an electronic record. The present invention permits
caregivers to easily input chart data directly into the computer.
In addition, the computer receives information automatically from
various monitors and medical devices such as vital signs monitors,
IV pumps, and the like. Therefore, all data related to the patient
is captured at a single location which is located at the point of
care. Logon to the computer system of the present invention may be
controlled by an IR or RF badge worn by the nurse or caregiver. The
computer is designed to remain with the patients in the hospital
room and during ambulation or transportation in the hospital. In
other words, the computer follows the patient wherever the patient
goes from admit to discharge.
[0004] Providing a computer at the point of care improves
communication. Lab and radiology results are presented
electronically to the ordering and consulting physicians at the
point of care. The computer system of the present invention
facilitates patient care by virtual teams which never actually meet
when caring for the patient. The computer system instantaneously
captures information related to the patient as well as laboratory
procedures and diagnostic procedures ordered for the patient.
Information is displayed in an electronic chart or flow sheet on a
display. Illustratively, two adjacent display screens are used to
display the patient information. There is little delay in inputting
this information to the patient's chart. Such delays often occur
with conventional paper charts. Therefore, the present invention
reduces the likelihood of ordering redundant lab or diagnostic work
on the patient. Electronic referrals, authorizations, and
consultations are fast, secure and reliable. E-mail or intranet
communications are used to transmit data and automate
prescriptions, lab orders, and work flow.
[0005] A computer system provides updated access to information and
communication at the point of care. Patient data is stored in a
memory of the computer or in a main server coupled to the computer
by a communication network. Access to all patient information is
available to physicians, pharmacy, radiology, lab, cath lab, or any
PC connected to the computer at the point of care through a
communication network. Doctors or other caregivers at remote
locations can view information related to the patient by connecting
to the patient's computer or the main server through the
communication network. In other words, the computer system acts as
a node on the network and can access information from other
nodes.
[0006] The present invention is also able to capture costs of
services and transmit the cost information for billing purposes.
For instance, the computer system of the present invention uses a
wireless data receiver to receive signals from a badge on the
caregiver and from tags on equipment located within the hospital
room. Therefore, the computer system of the present invention can
determine the actual cost of providing services to the patient. The
computer system also includes an input device such as, for example,
a keyboard or a bar code reader to capture costs of medication or
other treatment or articles used by the patient.
[0007] The system of the present invention may be used with the
COMposer.RTM. communication system available from Hill-Rom. Some
details of the COMposer.RTM. system are disclosed in U.S. Pat. Nos.
5,561,412; 5,699,038; and 5,838,223 which are incorporated herein
by reference.

patient monitoring system comprises a computer, an input device
coupled to the computer and configured to input patient
information, and first and second display screens coupled to the
computer. The computer displays a first portion of the patient
information on the first display screen and a second portion of the
patient information on the second display screen.
[0009] In an illustrated embodiment of the present invention, a
system comprises a computer including a memory, and a medical
device for treating a patient. The medical device includes an
indicator configured to provide a signal indicating when the
medical device is in use to treat the patient. The system also
includes a coupler coupled to the computer for receiving the input
signal from the indicator. The computer is configured to store the
amount of time that the medical device is in use to treat the
patient in the memory.
[0010] In one illustrated embodiment, the computer is configured to
generate a bill for use of the medical device based upon the amount
of time that the medical device is used to treat the patient. The
medical device illustratively includes a unique identification so
that the computer generates an itemized bill indicating the
particular medical device used to treat the patient.
[0011] In another illustrated embodiment of the present invention,
patient care computer system is provided for use by a caregiver
wearing an identification badge which includes a wireless data
transmitter that uniquely identifying each caregiver. The apparatus
comprises a computer including a memory for storing patient
information, a display screen coupled to the computer, an input
device coupled to the computer for inputting patient information, a
wireless data receiver coupled to the computer, and means for
detecting when a caregiver enters a room in which the computer and
patient are located. The detecting means determines whether the
caregiver is authorized to use the computer system and, if so,
automatically logging the caregiver in to the computer system.
[0012] In another illustrated embodiment of the present invention,
a system comprises means for monitoring at least one physiological
condition of a patient on a real time basis, means for recording
information related to a treatment of the patient and the time that

DETAILED DESCRIPTION OF THE DRAWINGS
[0084] Referring now to the drawings, FIG. 1 illustrates a block
diagram of a patient point of care computer system 10 of the
present invention. Computer system 10 is designed to provide
improved access to data at the point of care. Centralized computer
system 10 organizes numerous monitors, treatment devices, and
therapy devices and facilitates record keeping by providing a real
time electronic chart for the patient. The computer system 10 of
the present invention also improves communications between various
caregivers who are members of a care team for the particular
patient. The computer system 10 automates processes for ordering
tests and communicating between various caregivers working with a
patient.
[0085] Computer system 10 includes a computer 12 which is designed
to stay with the patient during an entire stay at a hospital or
other medical facility. Computer 12 is coupled to a memory 14 for
storing and retrieving data. Computer 12 is also coupled to a
display 16 which illustratively includes first and second displays
18 and 20 as discussed below in detail. Computer 12 is further
coupled to at least one input device 22. The input device 22
includes a pen or stylus based input, a keyboard, a mouse, a
joystick, a voice recognition input, a touch screen, or other
suitable input device. The input device 22 permits a caregiver or
other individuals to input patient information or other desired
information into the computer 12.
[0086] Computer 12 is also coupled to a communication network 24.
Communication network 24 permits computer 12 to transmit and
receive information from a remote location. Information related to
the patient stored in memory 14 of computer 12 can be accessed by a
doctor at a remote location. In addition, e-mail messages or other
order messages can be transmitted over the communication network 24
to other locations both inside and outside the hospital. Therefore,
a caregiver can schedule tests or request certain medications or
procedures using the input device 22 of computer 12. These orders
or prescriptions are then automatically transmitted over the
communication network 24 to the proper location. In addition,
information such as test results can be sent over the communication
network to computer 12 so that the caregiver can access all
information related to the patient at the point of care.
[0087] As discussed below, the computer 12 may be coupled to
monitors 26, treatment devices 28, and therapy devices 30 through a
physiological monitoring module or coupler 32. Illustratively,
coupler 32 may be an RS-232 part or other suitable connector.
Computer 12 processes signals from the monitors 26, treatment
devices 28, and therapy devices 30 on a real time basis. This
information is used to provide an electronic chart of patient
conditions on display screens 18 and 20. The monitors 26, treatment
devices 28, and therapy devices 30 include, but are not limited to,
heart rate monitors, temperature sensors, blood pressure monitors
(invasive and noninvasive), EKG monitors, blood oxygen sensors,
capnographs, ventilators, IV pumps, scales, chest drainage
monitors, and the like.
[0088] Computer 12 is also coupled to a bar code reader 34. Bar
code reader 34 is either a standard bar code reader or a 2D bar
code reader. The bar code reader 34 permits a caregiver to scan a
bar code to indicate the type of drugs given to the patient in
order to capture costs and the time that the drugs are
administered. Bar code reader 34 may be used on any other item
given to the patient or on equipment in the room. An RFID
receiver/reader 35 is also coupled to the computer 12 in another
embodiment to read transmitted RFID signals.
[0089] Computer 12 is also coupled to a wireless data receiver 36.
Data receiver 36 is illustratively an IR or RF receiver. It is
understood, however, that the wireless data receiver could be any
type of receiver. Receiver 36 is configured to receive transmission
signals from wireless transmitters 38. Transmitters 38 are
typically included in badges worn by personnel or on tags on
equipment. As discussed below, the wireless data receiver 36
monitors the time and type of equipment and personnel within the
vicinity of the point of care. Computer 12 is also coupled to a
wireless data transmitter 40. Transmitter 40 is configured to
transmit signals to a receiving station within the hospital such
as, for example, when computer 12 is disconnected from the
communication network 24 during transport of a patient from one
location to another.
[0090] Computer 12 is also coupled to a camera 42. Video signals
from camera 42 can be transmitted by computer 12 to a remote
location using the communication network 24 or the wireless data
transmitter 40. An Internet protocol such as video over IP may be
used if desired. Therefore, a doctor at a remote location can view
an image of the patient. The video signal from camera 42 may also
be taped using conventional magnetic tape storage devices.
[0091] In an illustrated embodiment, computer 12 is also connected
to the phone 44. Therefore, the caregiver or patient can use the
phone 44 to place telephone calls in a conventional manner or using
an Internet protocol such as voice over IP. In addition, messages
or warnings can be transmitted by the computer 12 over phone 44.
For instance, if a caregiver receives an e-mail message on computer
12, the message can also be transmitted to the caregiver via phone
so that the caregiver can be paged or delivered a message by voice
mail. Voice mail message or instructions received on the phone line
can also be converted to e-mail message and transmitted to another
location via communication network 24 or transmitter 40 or stored
on computer 12 for access by a caregiver at computer 12.
[0092] The computer system 10 provides access to information at the
point of care from the lab, pharmacy, radiology, and other
locations that may be inside or outside of the hospital but that
generate information relevant to the care of the patient. An
electronic record is stored in memory of a server 15 coupled to
computer 12 by communication network or wireless connection for
access by the computer 12 at the point of care. However, it is
within the scope of the invention as presently perceived to instead
or additionally store the electronic record in memory 14 of
computer 12 for access at the point of care. Patient information
data is integrated on to a chart which is displayed on the large
display 16 including both display screens 18 and 20. The computer
system 12 integrates data manually input into the computer using
input devices 22 with real time data available from monitors 26,
treatment devices 28, therapy devices 30, bar code reader 34, and
wireless data receiver 36. As discussed below, the computer 12
remains with the patient during transport and at the other
locations in the hospital such as, for example, for diagnostics,
the operating room, and the like.
[0093] FIGS. 2-10 illustrate various embodiments of components of
computer system 10 of the present invention. FIGS. 2 and 3
illustrate display 16 which includes a first display screen 18 and
a second, removable display screen 20. Display screen 20 is on a
removable module 50 which is removable from a support 52, having a
support plate 54 and a handle 56 coupled to the support plate 54.
It is understood that a single larger, elongated display may be
used instead of separate display screens 18 and 20. However, for
cost reasons or other reasons, two displays 18 and 20 are used to
provide the larger overall display 16. It is also understood that
more than two display screens may be coupled to support 52 if
needed as discussed below.
[0094] In the illustrated embodiment, display screen 18 is fixed to
the support 52. Bar code reader 34 is storable within a recess 58
of support 52. Bar code reader 34 is removed in the direction of
arrow 60 for scanning items such as drugs or equipment supplied to
the patient. Input device 62 is also coupled to the support 52.
Plate 54 illustratively includes a connector 64 which automatically
provides connection between module 50 and the rest of the system
when the module is loaded onto support 52 in the direction of arrow
66. It is understood that various connecting cords may also be used
to couple module 50 to the other components of computer system 10.
The connector 32 is configured to couple signals from monitors 26,
treatment devices 28, and therapy devices 30, to an inlet port on
module 50 when connector 32 is installed in the direction of arrow
68 of FIG. 2. Wireless data transmitter 36 may also be coupled to
module 52 by installing the transmitter 40 in the direction of
arrow 70.
[0095] The computer system 10 uses both display screens 18 and 20
to provide a flow sheet dimension in order to display the flow
sheet for the patient in electronic form so that the paper chart
does not have to be manually updated. As discussed below in detail,
real time data from monitors 26, treatment devices 28, and therapy
devices 30, are used to continuously update the flow sheet with
real time data. The caregiver can input information into the
computer 12 using an input device such as the stylus or pen 72
shown in FIG. 3. Illustratively, display screens 18 and 20 include
touch screen technology so that information can be input by simply
touching portions of the screen. In addition, an input pad section
74 permits the caregiver to write with the pen 72 to input
information. Computer 12 includes handwriting recognition software
such as, for example, CalliGrapher 5.3 for Windows software
available from ParaGraph, so that computer 12 recognizes the
characters written on input pad 74.
[0096] FIGS. 4 and 5 illustrate another embodiment of the present
invention. Those numbers referenced by numbers from FIGS. 1-3
perform the same or similar function. In FIG. 4, base support 52
includes a housing 76 formed to include an aperture 78 for
receiving the pen 72 in the direction of arrow 80.
[0097] A physiological monitoring module 82 is coupled to housing
76. Module 82 includes a plurality of sockets 84 configured to
receive connectors 86 coupled to the monitors 26, treatment devices
28, or therapy devices 30, as illustrated by arrows 88. FIG. 5
illustrates the caregiver inputting information using the pen 72. A
handle 51 is coupled to module 50 to permit easy removal of the
module 50 from the remainder of support 52. An arm assembly 53 is
configured to couple the computer system 10 to a suitable support
structure in the room, on the bed, or on a separate cart or stand,
as discussed below in detail.
[0098] Another embodiment of the present invention is illustrated
in FIGS. 6-8. This embodiment shows a modular physiological
monitoring interface 90 configured to be coupled to module 50.
Physiological monitoring interface 90 includes a separate housing
92 having a locking mechanism 94 configured to secure the interface
90 to a support plate 96 which is pivotably coupled to a support
arm 98. Physiological monitoring interface 90 further includes the

receiving connectors coupled to the monitors 26, treatment devices
28, and therapy devices 30. The wireless data transmitter card 102
is also coupled to the interface housing 92. Physiological
monitoring interface 90 may include its own processor and memory
for receiving the inputs from the various monitors 26, treatment
devices 28, and therapy devices 30. In another embodiment,
interface 90 provides a physical connection between the monitors
26, treatment devices 28, and therapy devices 30, with main
computer 12 located in module 50, but does not include any
processor of its own.
[0099] FIGS. 6 and 7 show module 50 which includes display screen
20 coupled to physiological monitoring interface 90. A lock 104 is
provided to secure module 50 to the interface 90. In the
illustrated embodiment, module 50 includes a connector 106
configured to mate with a connector on interface 90 to provide
electrical connection between the computer 12 within module 50 and
the interface 90. In another embodiment, a separate cord may be
used to provide the electrical connection between module 50 and
interface 90. In addition, when physiological monitoring is not
needed, module 50 can be coupled directly to base plate 96. Module
50 and interface 90 can be removed from base plate 96 as a unit as
shown in FIG. 7. Therefore, the computer 12 along with monitoring
capabilities may be coupled to the bed or a cart adjacent the bed
as discussed below for transport with the patient to various
locations within the hospital. If it is desired only to transport
module 50 including the computer 12 without the physiological
monitoring capability, module 50 is removed from interface 90 and
coupled to the bed or cart for transport with the patient to the
remote location.
[0100] FIGS. 9 and 10 illustrate yet another embodiment of the

incubator 160 for transport. Module 50 includes computer 12 and
display 20, as well as connector 32 for monitors 26, treatment
devices 28, and therapy devices 30. Therefore, computer 12
continues to capture real time data related to the infant 162
during transport. Wireless data transmitter 40 is used to
communicate with base units within the hospital during
transport.
[0104] FIG. 13 illustrates the computer module 50 coupled to the
wall in an examination room by bracket 170 and arm 172. The
examination room may be in the hospital, a doctor's office, or
other health care facility. In FIG. 13, a patient 174 is seated on
an examination table 176. Examination table 176 illustratively
includes a scale 178, having an output coupled to computer module
50 so that the weight of the patient is automatically recorded by
computer 12. It is understood that the entire computer system 12
including the dual display 16 discussed above may be used within
the examination room. However, for cost reduction purposes, a
single display on module 50 may be adequate for the examination
room. The temperature thermometer 180 and blood pressure cuff 182
are also coupled to the connector 32 coupled to module 50 by lines
184. Therefore, computer 12 automatically captures the patient's
temperature and blood pressure reading. The caregiver 186 inputs
additional information using input device 22 which is
illustratively a touch screen or pen based system. Patient symptoms
may also be entered so that a doctor entering the room later can
access complete information regarding the patient 174. This patient
chart information is coupled to a communication network 24 so that
the information can be transmitted to a remote location, such as a
hospital, if information related to the patient is needed at a
later time.
[0105] Another embodiment of the present invention is illustrated
in FIG. 14. In this embodiment, the wireless data receiver 36 is
used to receive data from badges 190 on caregivers 192. Tags 194
are also located on the medical equipment within the room. The
badges 190 and tags 194 transmit signals such as infrared signals
or RF signals which are received by receiver 36. The signals from
badges 190 and tags 194 include identification information to
identify the particular caregiver 192 or the particular type of
equipment located in the room. Computer system 12 monitors the time
that particular caregivers 192 and equipment are located within the
room. The signals from tags 194 can include status information
(such as in use or at rest). By knowing the location of equipment
and the status of the equipment at all times, the computer can
determine the amount of time that equipment is in use for each
patient. Therefore, the hospital can determine the real cost of
providing care to a patient 196. In addition, computer 12 can
generate an itemized bill indicating the time and duration that
equipment is used in treating the patient and the time spent by the
caregiver 12 within the room. This cost information can be either
maintained for internal purposes or transmitted to a billing
station for charging each patient for the exact amount of equipment
and caregiver time used.
[0106] In the illustrated embodiment, computer system 10 identifies
the caregiver 192 based upon signals transmitted from badge 190 to
receiver 36. Upon recognizing an authorized caregiver 192 entering
the room, computer 12 automatically logs the user onto the system
10. Any email or phone messages can be given to caregiver 192 via
the display 16. Caregiver 192 can also be alerted when results of
tests ordered by the caregiver 192 are available.
[0107] FIG. 15 illustrates another embodiment of the present
invention in which the computer system 10 is coupled to a bed 200
by a coupling mechanism 202 which includes a pin 204 configured to
be located within an IV socket 206 of bed 200. Pin 204 extends away
from hub 208. Hub 208 includes a bracket 210 which is pivotally
coupled to arm 212. The opposite end of arm 212 is pivotally
coupled to bracket 214 of computer system 10. An IV pole 216
supports IV bags 218 and pumps 220. By coupling the computer system
10 to bed 200, computer system 10 is transportable with the bed 200
during transport as shown in FIG. 17. Therefore, computer 12
continues to capture data from the monitors 26, treatment devices
28, and any therapy devices 30 on a real time basis during
transport of the patient within the hospital 10. Wireless
transmitter 40 and receiver 36 permit computer 12 to remain in
contact with the base station in the hospital during transport.
[0108] FIG. 18 illustrates another embodiment of the present
invention in which the removable module 50 has been removed from
support 52 and coupled to a cart 220. Cart 220 includes a base 222,
a support 224 for holding a ventilator 226, and pivotable IV poles
228 and 230. Illustratively, cart 220 is a Careporter cart
available from Hill-Rom, Inc. as disclosed in U.S. Pat. No.
5,966,760 and in U.S. application Ser. No. 09/105,255 which are
incorporated herein by reference. Cart 220 includes a pivotable
support arm 230 for receiving module 50. Module 50 includes display
20, connector 32, wireless data transmitter 40, along with computer
12, memory 14, and input device 22.
[0109] FIG. 19 illustrates a junction box 240 having a wireless
transmitter such as an RF transmitter 242. The junction box 240
includes a plurality of inlet connectors 244 configured to be
coupled to physiological monitors, IV pumps, or other devices 246
that do not have individual transmitters. For example, junction box
240 may be used in a critical care unit with all the devices 246
coupled to inlet connectors 244. Therefore, the hospital does not
have to undergo the expense of placing a transmitter on each device
246. Transmitter 242 transmits data from the devices 246 to the
wireless data receiver 36 of computer system 10 located on the bed
or a cart adjacent the bed.
[0110] Junction box 240 includes an internal memory 248 for storing
a selected amount of data from the devices 246. Power cord 250 for
junction box 240 is designed to be plugged into a suitable power
outlet.
[0111] Junction box 240 also includes a wireless receiver 252 for
receiving data from the wireless data transmitter 40 of computer
system 10. Junction box 240 also illustratively includes a
processor 240 which is programmed to recognize devices 246 coupled
to the junction box 240. Junction box 240 communicates with
computer 12, transmitter 242 and receiver 252. Processor 254
determines whether the computer system 10 is within range for
transmission of data by determining whether signals from the
computer system 10 are detected by receiver 252. If the computer 10
is within range for receiving data transmission from the junction
box 240, data from devices 240 is transmitted by transmitter 242
from data receiver 36 where computer 12 stores the data in memory
14. If computer system 10 is not within range to receive data,
processor 54 stores data from the devices 246 in memory 248 of
junction box 240. When processor again determines that computer
system 10 is within transmission range, processor transmits the
stored data from devices 246 to the wireless data receiver 36 of
computer system 10. Therefore, information for charting purposes is
supplied to computer system 10 without requiring transmitters on
each of the devices 246.
[0112] FIGS. 20-24 illustrate various uses for a patient assist
apparatus 260. Patient assist apparatus 260 includes a base 262
having casters 264. A support portion 266 is coupled to base 264.
Air or oxygen tanks 268 are coupled to support portion 266. IV
poles 270 are also coupled to patient assist 260. A handle 272 is
coupled to an upper end of support 266. A computer support 274 is
also coupled to the upper end of support 266. Computer support 274
is configured to receive computer module 50 which is illustratively
removed from the total computer system 10 as discussed above.
Module 50 includes a single display 20, a computer 12, memory 14,
wireless data receiver 36, wireless data transmitter 40, and
coupler 32 for connecting the computer 12 to monitors 26, treatment
devices 28, and therapy devices 30. Therefore, vital signs of the
patient 276 as well as outputs from various devices such as IV
pumps 278 are captured real time by computer 12. Display 20 also
displays the patient's vital signs. Patient data is transmitted via
the wireless data transmitter 40 to a communication network 24 or
stored in local memory. In FIG. 20, the patient assist 260 is used
as a walker-type device to assist with patient egress after medical
procedures such as surgery. The patient assist 260 helps the
patient 276 maintain his balance and keeps the computer 12 at the
point of care.
[0113] FIG. 21 illustrates the patient assist 260 and computer
module 50 for use as an IV pole within the room. Caregiver 280
inputs information related to the patient 276 using pen 72 as
discussed above. FIG. 22 illustrates the patient assist 260 coupled
to a wheelchair 282. Caregiver 280 uses handle 272 to push the
wheelchair 282. A coupling mechanism is used to secure the patient
assist 260 to the wheelchair 282. Again, computer module 50 is able
to monitor and record data from monitors 26, treatment devices 28
and therapy devices 30 during transport of the patient. In
addition, all the patient's information and chart are available on
display 20 during transport. FIG. 23 illustrates removable module
50 from support 52 within the room as illustrated by arrow 284.
Module 50 is then loaded on to patient assist 260 as illustrated by
arrow 286 for transport of the patient on the bed 290. Caregiver
280 is able to view the patient's chart and vital signs during
transport on display 20. Patient assist 260 is coupled to bed 290
by a suitable latching mechanism. FIG. 24 illustrates that the
patient assist 260 may be uncoupled from bed 290 at the testing
facility such as the CT scanner 292. Patient 276 is removed from
bed 290 and placed on table 294. Patient assist 260 is uncoupled
from bed 290 and left beside the patient 272 when the bed 290 is
removed from the room. Therefore, computer 12 located within module
50 continues to capture patient data and data from the monitors and
treatment devices while the patient 270 is at the testing facility.
All previous test results and chart information are available to
the caregiver at the test facility. In addition, the chart remains
complete on a real time basis. In certain instances, test results
can be automatically transmitted to computer 12. In other
instances, test results are obtained later and transmitter to the
computer 12 via the communication network 24. Since all test
results and lab results are available at the point of care, the
present invention reduces the likelihood of duplicate testing on
the patient 272.
[0114] In the embodiment of FIGS. 20-24, data related to the
patient is transmitted by wireless data transmitter to a central
nurse station or to the main server for transmission to any
location. Therefore, patient's vital signs or other information can
be displayed or monitored at the central station.
[0115] When in the room, the computer system 10 is also used as a
tool to educate the patient. Information related to the patient's
particular diagnosis or condition is provided to the patient so
that the patient understands the care plan for treating the
patient's condition. Computer 12 is also used to assist compliance
with a doctor's instructions after release. For instance,
informative information can be provided on display 16 with
instructions for the patient after release. Display 16 can also be
used as a TV set when the caregiver is not in the room.
[0116] FIGS. 25-27 illustrate a workstation 300 located in a
hospital room adjacent the bed 302. It is understood that the
workstation 300 can be used in the hallway or at another location
outside the hospital room. Computer system 10 is shown on an

Work surface 378 includes handles 380 and 382. Either module 50 of
computer system 10 or the entire computer system 10 is configured
to be coupled to a support 382. Pullout keyboard 384 is located
under work surface 378. Surface 378 may include an input device
such as device 74 in FIG. 2 which permits the caregiver to write
out information to be input into the computer 12 which is
recognized by handwriting recognition software.
[0119] Yet another cart 390 is illustrated in FIGS. 32 and 33. Cart
390 includes a central portion 392 having drawers 394. Legs 396 and
casters 398 are coupled to central portion 392. Stand 390 includes
an angled top work surface 400 and a keyboard 402 which can be
moved to an extended position in the direction of arrow 404 in FIG.
33 for access by a caregiver 406. Computer 10 is coupled to a
telescoping support arm 408 by a pivot connection 410. Arm 408 can
extend and retract in the direction of double-headed arrow 412 in
FIG. 33 to raise and lower the height of computer 10. Computer 10
is also pivotable about axis 412 as illustrated by double-headed
arrow 414 in FIG. 33.
[0120] FIG. 34 illustrates a summary of the real time electronic
charting feature of the present invention. As discussed above, dual
displays 18 and 20 permit replication of a chart approximately the
size of a conventional flow sheet used to keep patient records in
the hospital. The dual displays 18 and 20 also permit viewing of
two separate software application simultaneously. It is understood
that a single display may be used. However, dual displays are used
for cost saving purposes in order to provide the chart information.
In other words, a portion of the chart data is displayed on the
first display screen 18 and another portion of the patient data
chart is displayed on the second display screen 20. Computer 12
inputs information in a real time basis on the chart from monitors
26, treatment devices 28 and therapy devices 30. In other words,
the computer 12 monitors these devices to provide real time
information which normally is kept on patient's charts or flow
sheets. For example, computer 12 automatically charts information
related to temperature, respirations, rhythm, heart rate, blood
pressure, blood oxygen levels, or any other vital sign which is
desirable to monitor. The computer 12 graphs this information on a
continuous, real time basis on the chart.
[0121] Computer 12 also monitors the bed status as illustrated at
block 420. Bed status 420 includes information related to the
location of various bed deck sections or other information related
to the mechanical features of the bed. Computer 12 also monitors
bed based therapy devices as illustrated at block 422. These
therapy devices include, for example, thermal treatment devices,
percussion, vibration, or rotation therapy provided for the
patient. Computer 12 monitors the actual time and duration that
such therapies are performed. Computer 12 indicates these therapies
on the chart so that the results of these therapies can be
monitored for effectiveness by viewing the time that the therapy is
performed and then determining whether the patient's condition
improves based on the therapy. Computer 12 also monitors
medications administered using the bar code reader 34, RFID reader,
or other input device as indicated by block 424. Again, by charting
these medications on a real time basis, the caregiver can determine
the effectiveness of medications by monitoring the other vital
signs in relation to the time that medications are administered.
Test results are also monitored by computer 12 as illustrated at
block 426. These test results are charted, if appropriate, to
assist with analysis of the effectiveness of the various
treatments. As discussed above the charting from the monitors
continues regardless of whether or not the patient is in the room.
The modular interface card is provided for connecting the monitors,
treatment devices, and therapy devices to the computer system 10.
An open system permits devices from various manufacturers to be
coupled to the system 10. Therefore, vital signs are archived and
automatically downloaded to the flow chart regardless of whether or
not the patient is in the room. This provides a more complete chart
when compared to conventional paper charts.
[0122] Computer 12 may also be coupled to a smart mattress such as
disclosed in PCT Application No. PCT/US99/25311 which is
incorporated herein by reference. The smart mattress generates
output signals related to a patient's weight, heart rate,
respirations, temperature, EKG, ECG, SaO.sub.2, and the like which
are monitored and charted by the computer 12.
[0123] Another embodiment of the present invention is illustrated
in FIG. 35. The embodiment of FIG. 35 provides a fully integrated
care delivery system 500. The system 500 provides open architecture
which allows medical equipment manufacturers to produce module
products to function with the system 500. These medical device
manufacturers access common hardware and redundant systems so that
the modular devices are smaller and lighter. The smaller and
lighter modular devices facilitate ergonomic benefit and their
placement within the environment. The entire system 500 also has
cost advantages by reducing these redundant systems. System 500
includes a central station having a central processing unit (CPU)
504, a power supply 506, a battery backup 508, a display 510, and a
graphical user interface 512. User interface 512 may include any
type of input device discussed above. Medical device modules 514
configured to be coupled to a plurality of input connectors 516 of
station 502. Illustratively, the medical devices of modules 514 are
vital sign monitors, IV pumps, ventilators, defibulators,
compression boots, and other medical devices that may be used to
provide or monitor the care of a patient. Modules 514
illustratively do not include a CPU, a power supply, a display, or
a user interface. When modules 514 are connected to connector 516,
modules 514 include a suitable connector 518 so that modules 514
use the CPU 504, power supply 506, battery backup 508, display 510,
and user interface 512 of the central station 502.
[0124] Central station 502 provides an open architecture to allow
all medical equipment manufacturers to produce modules 514 to
function with the system 500. System 500 includes other components
(not shown) such as the connection to the communication network 24,
the bar code reader 34, wireless data receiver 36, wireless data
transmitter 40, camera 42, and phone 44 as discussed above with
reference to FIG. 1. CPU 504 also accesses memory 518. Modules 514
are less expensive since redundant systems are not used. Only the
actual treatment portions of the devices are required in the
modules 514. Control of the modules 514 is provided using the
graphic user interface 512 of station 502. Information regarding
operation of the module 514 is displayed on display 510 instead of
on a separate display on the module 514. Power is supplied to the
module 514 via the power supply 506 if the station 502 is connected
to a wall outlet or via a backup battery 508 if the station 502 is
disconnected from the wall outlet such as, for example, during
transport. Once the modules 514 are connected, the system 500
operates as discussed above to capture data for charting patient
information throughout the patient's entire stay at the
hospital.
[0125] FIGS. 36-38 illustrate an embodiment of the invention shown
in FIG. 35. This embodiment, a cart 520 includes a base 522

and width dimensions 640 and 642 of first display 632 are larger
than the height and width dimensions 644 and 646 of second display
634. Therefore, the removable display 634 is smaller than the
stationary display 632. A top edge 648 of first display 632 is
illustratively aligned with a top edge 650 of second display 634 on
support 636. In the illustrated embodiment, chart information or
other patient information is provided on both displays 632 and 634.
Illustratively, the charting data is only provided in a top portion
of display 632 as illustrated by dimension 652. Dimension 652 is
the same height as height dimension 644 of second display 634. A
lower portion of first display 632 illustrated by dimension 654 is
illustratively used for providing menu items or icons. Section 654
of screen 632 may also be used as a pen or stylus based input
section which provides handwriting recognition as discussed above.
It is understood that additional display screens may be coupled to
base 636, if desired.
[0128] When it is desired to transport the patient or permit the
patient to move about in the hospital, the computer 12 and display
634 are removed from base 636 and coupled to the bed, patient
assist, stand or other device as discussed above so that the
computer 12 and display 634 remain with the patient at the point of
care as the patient moves throughout the hospital. The other
components of computer system 10 permit real time monitoring and
data entry as discussed above.
[0129] FIG. 42 illustrates another embodiment of a physiological
monitor signal junction box and transmitter of the present
invention. In the illustrated embodiment, monitoring module 660
includes a housing 662 which is coupled to the patient 664 by strap
666. It is understood that the housing 662 may be coupled to other

FIGS. 54 and 59. Side portions 870 move outwardly as shown in FIG.
59 as the support is pivoted in the direction of arrow 882. Support
860 is shaped to provide spaced apart support legs 874 and 876
which are configured to engage plates 748 and 750 as shown in FIG.
53 to support the seat 856.
[0160] When it is desired to use the seat 762, an operator pivots
the seat 856 upwardly about mounting member 850 in the direction of
arrow 878 in FIG. 54. As the seat 856 is lifted, support 860 pivots
downwardly about axis 866 in the direction of arrow 880 in FIG. 59
until the side portions 870 enter notches 868 formed in couplers
862 to hold the support 860 in the position shown in FIG. 60.
Therefore, the support 860 automatically pivots downwardly and is
maintained in the support position by couplers 860 when the seat
856 is pivoted upwardly.
[0161] When it is desired to move the seat 862 to a storage
position, the user first pivots the support 860 about axis 866 in
the direction of arrow 882 shown in FIGS. 53 and 60. Support 860
pivots to be generally co-planar with seat 856 as shown in FIG. 54.
Seat 856 holds the support 860 in the position shown in FIG. 54 for
storage.
[0162] FIGS. 53 and 54 also illustrate the handle assembly 764.
When in the orientation shown in FIG. 53, a patient may use the
handles 884 and 886 for support or like a walker. A center bar 887
extends between handles 884 and 886. Handle assembly 764 is coupled
to cart 740 by coupling mechanisms 890 best shown in FIGS. 61, 63
and 64. Handles 884 and 886 are pivotable by an axis 891 in the
direction of arrow 888 in FIG. 53 to lie on an opposite side of
support tubes 56 and 58 as shown in FIG. 54. In the FIG. 54
orientation, the handles 884 and 886 are usable by a caregiver to
push a bed, wheelchair or other device attached to the patient
assist cart 740.
[0163] As shown in FIGS. 61 and 62, the center rod 887 includes a
cylindrical body portion having a flat sections 892 adjacent
opposite ends. End couplers 894 are coupled to bar 887. Each
coupler 894 includes an aperture 896 configured to receive an end
of a handle 884, 886. A stop 898 is located on each coupler 894. As
best shown in FIGS. 63 and 64, mounting mechanisms 890 include an
aperture 900 formed to receive support tubes 756 or 758. When the
handles 884 and 886 are pivoted upwardly as shown in FIG. 63, the
flat sections 892 on center bar 887 are aligned with an opening 902
formed in coupling mechanism 890. A Belville washer 904 and a
friction member 906 are located within the opening 902. An inner
surface of friction member 906 illustratively has a cylindrical
shape to engage an outer surface support tube 756 or 758. When the
flat section 892 is aligned with opening 902 as shown in FIG. 63,
the mounting mechanisms 890 can slide up and down on support tubes
756 and 758 in the direction of double headed arrows 908 in FIG.
53. FIG. 54 shows the handle assembly 764 moved downwardly. Handles
884 and 896 provide arm rests for the seat 856 in this
orientation.
[0164] When the handles 884 and 886 are pivoted downwardly in the
direction of arrow 910 in FIG. 64, center bar 887 rotates in the
direction of arrow 912 which causes an outer cylindrical portion of
bar 887 to engage Belville washer, thereby compressing the Belville
washer and moving the friction member 906 into engagement with an
outer surface of tubes 756 and 758. Therefore, the handle assembly
764 is held in position on support tubes 756 and 758.
[0165] When the patient assist cart 740 is used to push a hospital
bed or wheelchair, the handles 884 and 886 are rotated beyond the
support tubes to the position shown in FIG. 54. The cylindrical
surface of center bar 887 also compresses the Belville washer 904
and moves the friction member 906 against posts 756, 758 when in
the FIG. 54 orientation. A shuttle lock 916 on each mounting
mechanism 890 is pressed inwardly to move the shuttle member 916
into alignment with stops 898 on couplers 894 to lock the handles
in the position shown in FIG. 54. Shuttle member 916 is moved in an
opposite direction when it is desired to pivot the handles back to
the position shown in FIG. 53.
[0166] FIG. 65 illustrates a caster braking mechanism 760 of one
embodiment of the present invention. Support tubes 756 and 758 are
each illustratively mounted over an inner tube 920. Support tubes
756 and 758 are biased upwardly in the direction of arrow 922 by a
spring 924. A coupler 926 is coupled to each support tube 756, 758.
Coupler 926 includes spaced apart arms 928 and 930. Casters 754 are
rotatably coupled to plates 748 and 750 for rotation about axis
932. Casters 754 include a stem 934 having a rotatable brake
actuator 936 configured to actuate an internal brake 938 when the
actuator 936 is rotated about its longitudinal axis 940.
Illustrative, casters 754 are model number 2944 casters available
from Tente, although any suitable caster may be used. An arm 942
has a first end pivotably coupled to coupler 926 by a pin 944
extending between arms 928 and 930. On opposite end of arm 942
includes an elongated slot 946 located over actuator 936.
Illustratively, the slot is sized so that opposite side walls
engage opposite sides of hex shaped actuator 936. When user uses
patient assist cart 740 as a walker and pushes down on handles 884
and 886 with enough force, support tubes 756 and 758 are forced
downwardly in the direction of arrow 948 by the patient's weight.
Similarly, when the user sits on seat 762, the user's weight moves
support tubes 756 and 758 downwardly in the direction of arrow 948.
Couplers 926 also move downwardly causing arm 942 to pivot about
axis 940, thereby rotating actuator 936 and braking the castor
754.
[0167] In another embodiment of the present invention, the support
tubes 756 and 758 are mounted directly over a tube on the casters
and spring biased upwardly. Therefore, application of weight to the
support tubes cause a brake coupled to the support tubes to engage
the casters.

[0171] FIG. 73 illustrates a wheelchair 1062 coupled to the patient
assist cart 740. Front wheels 1064 of wheelchair 1062 are
illustratively supported off the ground and latched to the base 742
by latch members 1066. Therefore, a caregiver can push the
wheelchair 1062 and the patient assist cart 740 in a normal manner
using handles 1068 of wheelchair 1062. The patient assist cart 740
can also be coupled to a rear surface 1070 of wheelchair 1062 using
locking pins similar to those discussed above. In this embodiment,
handles 884 and 886 are pivoted to the position shown in FIG. 54
and used to push the wheelchair 1062 and patient assist cart
740.
[0172] FIGS. 74-76 illustrate another embodiment of a dual screen
display 1100 of the present invention. Display 1100 includes a
housing 1102 having a first housing portion 1104 coupled to a
second housing portion 1106 to define an interior region
therebetween. First and second display screens 1108 and 1110 are
located within the interior region of housing 1102. As shown in
FIG. 75, first housing portion 1104 includes an outer flange 1112
configured to engage an edge 1114 of second housing portion 1106.
Illustratively, a gasket or other seal is provided to provide a
waterproof seal for the housing for holding the first and second
display screens 1108 and 1110. As shown in FIG. 75, power supplies
1116 and electric components 1118 for converting electrical signals
for display screens 1108 and 1110 are located on first housing
portion 1104. Second housing portion 1106 includes a mounting
region 1120 configured to be coupled to the head 950 of arm
assembly 804.
[0173] Details of the display 1100 coupled to arm 804 are shown in
FIG. 77 and 78. Illustratively, arm 804 is coupled to a primary arm
1122 by a coupler 1124. Base 964 of arm 804 is pivotably coupled to
coupler 1124 about axis 1126. Coupler 1124 is pivotably coupled to
primary arm 1122 about axis 1128. On opposite end of primary arm
1122 is pivotably coupled to another coupler 1130 about pivot axis
1132. Coupler 1130 is pivotably coupled to a mounting bracket 1134
about a pivot axis 1136. The arms 1122 and 804 can therefore be
moved to a plurality of different orientations in a room to
facilitate viewing and data entry into the computer as discussed
above. A protective frame 1138 is coupled to display 1104 to
protect the display. The arms 804 and 1122 also move the display
1100 to an ergonomic position for entering data as shown in FIG.
81.
[0174] Another embodiment of a primary arm is illustrated in FIGS.
79A-79C. Primary arm 1140 is coupled to secondary arm 804 to
support a cantilevered load such as display 1100 as indicated at
location 1142. Primary arm 1140 supports the bearing load at
location 1144. Arm 1140 includes three separate linkage arms 1146,
1148 and 1150 which are grounded at locations 1152, 1154 and 1156,
respectively. A rigid coupler 1158 is pivotably coupled to each arm
1146, 1148, 1150 by connections 1160, 1162 and 1164, respectively,
that form a triangular pattern. FIG. 79A illustrates the primary
arm at a +70 degree angle. FIG. 79B illustrates the configuration
of primary arm 1140 at a zero degree angle, and FIG. 79C
illustrates the position of primary arm 1140 at a -70 degree angle.
Primary arm 1140 is illustratively two four bar linkages which are
out of phase by 90 degrees to achieve maximum stability. As shown
in FIG. 79B, an extension spring 1166 is coupled to one of the
linkage arms 1146, 1148, or 1150. Extension spring 1166 is similar
to the spring shown in U.S. Pat. No. 5,826,846, which is
incorporated herein by reference.
[0175] When primary arm 1140 is at its uppermost angle (i.e. +70
degrees), little or no balance force is required to maintain the
angular position of display 1100. At this position extension spring
1166 is in its natural unextended position and does not provide any
counterbalance force to primary arm 1140. As primary arm 1140
rotates the amount of balance force necessary to hold display 1100
in a neutral position increases linearly with the angle of
rotation. As the rotation occurs, spring 1166 extends and supplies
a counterbalance force that also increases as spring 1166 extends.
Thus, the necessary balance force required by display 1100 is
offset by the extension force supplied by spring 1166.
[0176] FIGS. 80-82 illustrate the patient assist cart 740 and the
dual display 1100 located in a hospital room 1200. A patient 1202
is located on a bed 1204. The patient assist cart 740 is located
adjacent a head end of bed 1204. Therefore, computer 800 on patient
assist cart 740 continues to collect patient information while the
patient is in room 1200. Computer 800 is configured to drive the
dual display 1100 when the patient assist is in the room 1200. A
cable 1206 extends from computer 800 to the display 1100. A head
wall 1210 which is coupled to wall 1212. A light 1214 is coupled to
wall 1212 above head wall 1210. In FIG. 80, the dual display 1100
and arms 804 and 1122 discussed above are moved to a configuration
to position the dual display 1100 in a region 1216 located between
the light 1214 and the head wall 1210. Display 1100 is very close
to wall 1212 so that display 1100 is out of the way. In FIG. 80,
arm 1122 extends generally parallel to wall 1212 and arm 804
extends upwardly from arm 1122.
[0177] FIG. 81 shows the arms 804 and 1122 moved downwardly to
permit a caregiver 1218 to enter data into the computer using the
display 1100 as discussed above. The height and angle of display
1100 facilitate use by caregiver 1218 for data entry and viewing.
The arm 804 is configured to pivot the display 1100 and align the
display 1100 at an ergonomic angle of about 5 degrees to about 60
degrees relative to the ground for data entry and viewing.
Preferably the angle is about 20 degrees to about 40 degrees. FIG.
82 illustrates the arms 804 and 822 moved to an elevated position
so that the monitor may be viewed at a position above the head of
caregiver 1218. In FIG. 82, the display 1100 is out of reach of
children. The arms 1122 and 804 permit the display 1100 to be
located at the plurality of different orientations.
[0178] FIG. 83 illustrates additional details of the computer 800
which drives display screens 1108 and 1110 on display 1100 and also
drives display screen 802 on patient assist cart 740. Computer 800
illustratively includes two video cards 1230 and 1232. The first
video card 1230 drives both the display screen 802 on patient
assist cart 740 and the first display screen 1108 on display 1100.
The second video cart 1232 drives the second display screen 1110 on
display 1100. In other words, the images on display screen 802 and
display screen 1108 are the same. This reduces the cost of computer
800.
[0179] FIG. 84 is a block diagram illustrating one embodiment of
electronic circuitry for coupling the computer 800 located on a
patient assist cart 740 or work station to a dual monitor display
screen 1100 coupled to an arm 804, 1122 in the room. The computer
800 on the patient assist cart 740 includes a firewire link to the
dual screen display 1100. Main computer 800 illustratively includes
a mux-demux for video, touch screen, TCI/IP communications over the
firewire connection. The remote display 1100 has mux-demux with a
microcontroller for firewire protocol handling. It is understood
that other types of transmission line systems may be used to couple
computer 800 to display 1100. For instance, a Low Voltage
Differential Signaling (LVDS) interface may be used to couple
computer 800 to dual display screen 1100.
[0180] FIG. 85 is a block diagram illustrating an alternative
embodiment of electronic circuitry for coupling computer 800
located on the patient assist cart 740 to the dual monitor display
screen 1100. The FIG. 85 embodiment, computer 800 includes
mux-demux for sending PCI bus signals over the fire wire
connection. Display 1100 has mux-demux with a microcontroller to
convert PCI bus signals back to parallel form. LVDS is also an
alternative to the firewire in this configuration. FIG. 86
illustrates yet another embodiment of the electronic circuitry for
coupling the computer 800 on the patient assist cart 740 to the
dual monitor display screen 1110 on the support arm 804, 1122
within the hospital room 1200.
