Emergency facility video-conferencing system
Abstract
A medical video-teleconferencing and treatment system, having a
central video-conferencing station and one or more remote
video-conferencing stations and a communications link establishing
video-conferencing communication therebetween. A central video
monitor and audio system is located at the central
video-conferencing station, and a controller unit is coupled with
the communications link. The remote video-conferencing stations
each have a mobile emergency center cart including a remote video
monitor and audio system and a video-conferencing camera controlled
by the controller unit via the communications link and capable of
responding to control signals of the controller unit for panning
and zoom movement of said video-conferencing camera by a medical
practitioner located at the central video-conferencing station. The
arrangement enables the medical practitioner to observe and to
diagnose the condition of the patient and direct the medical
personnel of the selected video-conferencing station to provide
treatment of the patient.

Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates generally to the field of video-conferencing
wherein a two-way video and audio system is provided enabling one
or more parties at one location to be in communication with one or
more parties at another location. More specifically, the present
invention pertains to a medically related video-conferencing system
that is particularly suited to emergency medical activities and
enables a physician at a central location to diagnose and control
treatment of patients located at one or more remote medical
facilities. Even more specifically, the present invention concerns
the use of portable video-conferencing units at each of one or more
remote emergency facility locations and having components, such as
a video-conferencing CODEC (Compressor/Decompressor), that can be
controlled by the physician from the physician's central location
to thus enable efficient diagnosis of the patient and to ensure
proper treatment of the patient by the medical personnel of the
remote facility.
2. Description of the Prior Art
Although the field of video-conferencing has been under development
only in recent years, a number of processes, procedures and
interactive communications systems have been developed to enable
video-conferencing in a wide variety of commercial environments.
Examples of methods and apparatus associated with
video-conferencing are presented in U.S. Pat. No. 4,719,513 of
Peterson, U.S. Pat. No. 5,489,938 of Maruyama, et al. U.S. Pat. No.
5,767,897 of Howell, and U.S. Pat. No. 5,900,907 of Malloy, et al.
U.S. Pat. No. 4,719,513 discloses a compact video system in the
form of a mobile cart having compartments for containing video and
video recording equipment such as a video camera and video recorder
as well as a battery for providing a source of electrical power for
operation of the video and video recording system (VCR) in remote
conditions and to facilitate ease of using the equipment. The
mobile cart device is also provided with a camera mount enabling
the video camera to be appropriately mounted on the mobile cart for
use. U.S. Pat. No. 5,489,938 discloses television conference
apparatus in the form of a mobile cart which has a number of
storage compartments within which apparatus such as a video camera,
a manuscript table, a fax machine, etc. may be stored and may be
subsequently used simply by opening compartment doors, operating
lights or positioning equipment.
U.S. Pat. No. 4,755,881 also discloses a mobile cart within which
various video apparatus such as a video monitor, VCR, battery,
video camera, etc. may be stored so as to be readily available for
use. U.S. Pat. No. 5,900,907 discloses a video-conferencing unit
intended to be mounted to or supported by a video monitor and being
designed with a differential signal sensing sound system enabling
the video camera, or its lens to be automatically directed to the
source of the sound, i.e., such as an individual speaking at a
video conference, by the differential sound signal.
An interactive video/audio communications system has also been
developed for medical treatment of remotely located patients as set
forth in U.S. Pat. No. 5,810,755. In this case, a medical
practitioner's station is in communication with a medical treatment
station via video-conferencing apparatus each having video cameras,
audio speakers, etc. This particular medical apparatus is
particularly designed for ensuring identification of the patient
and for ensuring payment for medical services via credit card or
insurance card.
When a remotely located patient is being treated, especially during
emergency treatment at a remotely located emergency facility, the
patient's condition may not be well known. It is thus desirable for
a medical practitioner, located at a central facility to have the
capability of controlling the orientation of a patient inspection
video, including panning up or down, right or left and actuating a
zoom feature of the video lens. This feature will permit the
medical practitioner remote from the emergency facility to conduct
independent patient inspection and to discuss aspects of the
patient's condition with the medical personnel and perhaps also
with the patient during the time the local medical personnel are
engaged in the conduct of independent patient care of treatment
activities at the direction of the medial practitioner. It is
desirable, therefore, to provide an emergency room
video-conferencing system wherein a medical practitioner is enabled
via a video-conferencing system to direct medical personnel at
several remote locations to treat patients, particularly emergency
patients, according to diagnosis and treatment controlled by the
medical practitioner and further enabling the medical practitioner
to inspect the condition of the patient for the purpose of
diagnosis and to observe the medical treatment that is being
administered by local staff personnel.
To enable a medical practitioner, especially during emergency
conditions, to deliver high quality of medical care to a patient,
from the standpoint of close inspection and diagnosis, and to
ensure that local medical personnel, such as nursing personnel are
enabled to concentrate on patient treatment, rather than expend
time and effort manually positioning a video camera or a mobile
emergency center cart having a video camera, it is desirable that
the medical practitioner have the capability of independently
causing the video camera to move as desired for efficient visual
inspection of the patient, including close-up viewing of selective
portions of the anatomy of the patient. It is also desirable that
the medical practitioner have the capability of selectively
controlling the video-conferencing camera from a remote location
for video-conferencing with the nursing personnel at one or more
emergency medical centers and for viewing both the patient and the
nursing personnel at such one or more centers to thus ensure
delivery of the highest quality medical care to the patient.
SUMMARY OF THE INVENTION
It is a principle feature of the present invention to provide a
novel emergency room video-conferencing arrangement having a mobile
emergency center cart that can be positioned as needed within an
emergency room or other medical facility and having a video camera
enabling a remotely located medical practitioner to selectively and
independently control various aspects of the video camera and audio
equipment to thus enable the medical practitioner to visualize and
communicate with both the patient and the emergency room personnel
or closely inspect the physical condition of the patient so that
the medical practitioner can diagnose and control the patient's
treatment and visually inspect and talk with the patient prior to
and during treatment;
It is another feature of the present invention to provide a novel
emergency room video-conferencing arrangement wherein the mobile
emergency center cart is provided with an umbilical cord of
sufficient length to enable its connection with electronic signal
transmission and processing equipment connected to a wall mounted
connection of a remote medical facility, thus enabling the cart to
be positioned at any suitable location within an emergency room to
best facilitate proper diagnosis and treatment of the patient;
and
Another feature of this invention to provide a novel emergency room
video-conferencing arrangement wherein the emergency center cart
includes positional control apparatus for the video camera thereof
thus enabling the medical practitioner from a remote location to
selectively position the camera or its lens equipment as needed to
visualize the condition of the patient for diagnosis and to control
the character of treatment that is being delivered to the patient
by the medical personnel of the remote location.
It is also a feature of the present invention to provide multiple
emergency centers, each having an emergency center cart with
video-conferencing equipment, date transmission equipment and the
like which is selectively controllable via a communications link by
signals generated by a controller unit being selectively
manipulated by a medical practitioner at a central office remotely
located from the emergency center.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENT
Referring now to the drawings and first to FIG. 1 an emergency room
video-conferencing arrangement, according to the principles of the
present invention, is shown generally at 10 and may conveniently
take the form of a central office facility 12 within which is
located a video-conferencing unit shown generally at 14 having a
video monitor 16 and a video camera 18 having an electronic
remotely controlled signal receiving and transmitting system 19 for
video and audio communication via a communications link with a
remotely located video-teleconferencing unit. A speaker 20 is shown
to be connected by a speaker circuit cord 22 to the remote
controlled signal receiver and transmitter or to the video monitor
system, its function being to provide audio signals to and from the
remote emergency room locations so that the medical practitioner 24
is enabled to audibly communicate with nursing or medical personnel
at the remote location and also to communicate with the patient so
that proper diagnosis of the patient's condition can be efficiently
and accurately determined. The medical practitioner 24, typically a
licensed medical doctor, is provided with a controller unit 26
enabling electronic control signals 28 to be transmitted to the
signal receiver and transmitter portion of the
video-teleconferencing control unit 18. The controller unit 26 is
preferably a hand-held unit capable of transmitting signals in the
form of an infra-red (IR) beam to the integrated
video-teleconferencing control unit 19 for controlling one or more
video-teleconferencing units of remotely located emergency room
facilities or the like via one or more communications links.
The integrated video-conferencing control unit 19 is connected via
appropriate electronic circuits to a communications link circuit 30
which is in selective communication with the video-teleconferencing
units of a selected one of two or more remotely located emergency
room facilities 32-34. The controller device 26, operated by the
medical practitioner 24, is capable of being manually controlled to
individually select the equipment of one or more of the emergency
room facilities 32-34 as needed to diagnose and treat patients
located therein. As shown at the upper right hand portion of FIG.
1, a typical emergency center room 32 is provided with a bed or
gurney 36 on which is located a patient undergoing emergency
treatment. Each emergency room facility will be provided with one
or more medical personnel 38 (such as a nurse or other
non-physician medical professional) who provide hands-on treatment
of the patient under the direction of the medical practitioner 24
(such as a licensed physician), utilizing information communicated
by the medical practitioner 24 via the video-conferencing system.
Conversely, the medical practitioner 24 is enabled to utilize
information communicated visually and audibly as well as by other
communication links, such as medical data telemetry, so that proper
diagnosis of the patient may be established to thereby facilitate
the same medical treatment that would occur as if the medical
practitioner were present in the emergency room. The medical
practitioner is in video and audio communication with the nursing
personnel 38 and is in video and audio communication with the
patient on bed 36, if needed, and can inspect the medical treatment
during its progress by independently controlling the
video-conferencing equipment of the emergency center from the
central office facility. To ensure that the nursing personnel can
concentrate on the patient's treatment, and to also ensure that the
nursing personnel 38 will not have to touch the video-conferencing
equipment and can more adequately maintain the necessary sterile
conditions for quality patient care, the medical practitioner 24
has the capability of independently controlling various aspects of
the video-conferencing system, so that the nursing personnel 38
should have no need to touch the video-teleconferencing system
after it has been properly positioned to accommodate the patient
care that is being administered.
Each emergency room facility is also provided with a mobile
emergency center cart, shown generally at 40, which connected to
the communications link circuit 30 via an umbilical cord 42 which
is typically received by an umbilical cord connection mounted to
the wall structure of the emergency room facility. The emergency
center cart 40 may be powered by an electrical circuit contained
within the umbilical cord 42 and by connection to the electrical
power circuitry of the emergency room system. Other electrical or
electronic conductors of the umbilical cord 42 will provide video
and audio communications links to enable the medical practitioner
24 to be in visual and audio communication with both the nursing
personnel 38 and the patient and to likewise provide the nursing
personnel with both video and audio communication with a medical
practitioner so that diagnosis and treatment of the patient can be
conducted efficiently. The umbilical cord of the emergency center
cart will also have electronic conductors for telemetry of medical
data representing the vital signs of the patient, thus enabling the
medical practitioner to consider all relevant patient data that is
desirable for patient diagnosis and treatment.
Referring now to FIG. 2, an emergency center cart (EC cart) is
shown generally at 40 and incorporates a plurality of upright
structural members 44 which provide support for upper, intermediate
and lower support shelves or platforms 46, 48 and 50. These support
shelves may be adjustable relative to the upright structural
members to properly position the video-conferencing equipment
relative to the height of the nursing personnel. The upper support
platform or shelf 46 provides support for a video monitor 52 and is
located at an elevation so that the video screen 54 of the monitor
52 is located at an efficient viewing height, typically eye level,
for nursing or medical personnel standing in the emergency room.
The upper surface 56 of the video monitor 52 provides a support
surface for a video-conferencing unit shown generally at 58 having
an electronic signal transmitting receiving and processing unit 60
to which is controllably coupled a video camera 62. The video
camera 62 may itself be movable relative to the electronic signal
transmitting receiving and processing unit 60 or, in the
alternative or additionally, the video camera 62 may be provided
with a movable lens system enabling its field of view to be
selectively positioned by electronic controlled signals generated
by the controller 66 under the control of the medical practitioner
24. Additionally, the lens of the video-conferencing camera may be
adjustable for panning up, down, left and right and for zooming so
that the medical practitioner can efficiently inspect the patient
and communicate both audibly and visually with the nursing
personnel or other health care professionals of the emergency
center.
The intermediate support platform or shelf 48 is provided for
support of a document illumination device shown generally at 64
having a housing structure 66 within which may be located one or
more illumination devices such as incandescent or fluorescent
lighting elements. The housing will be provided with a light
transparent or translucent screen or document support plate member
68 through which light may be transmitted for illumination of the
image of an x-ray film or the like. The document support screen or
plate member 68 also provides for support of other relevant medical
data documents such as EKG's, lab reports, etc., that may be
visibly inspected by a document camera. For lighting such other
documents, a pair of lighting elements 70 and 72 are shown to be
positioned by support members 74 and 75, respectively, which extend
upwardly from the housing structure 66 of the document illumination
device 64. A document inspection video camera 76 may be supported
by the lower portion of the upper shelf or platform 46 but
preferably by a boom arm 77 from housing 66 and is positioned so
that its lens is directed to and focused on the screen or plate 68
of the document illumination device. Thus, whether the document is
an x-ray film, an EKG, a lab report or any other type of document
or whether it must be lighted or backlighted to be readable, it may
be inspected by the medical practitioner at the central office
location simply by appropriately manipulating the control device 66
and selecting operation of the document video camera 76 together
with one or both of the internal lighting devices and external
lighting devices of the document illumination device 64. The
intermediate support platform may also be adjustably connected to
the support structures to enable selective positioning of the
document support and lighting device relative to the document video
camera.
In the event the document video camera 76 should have a fixed lens,
the position of the support platform or shelf 48 is adjustable
relative to the upright structural members 44 so that the screen or
plate 68 or any document located on the plate will be precisely in
focus. If the document supported by the screen 68 should have a
particular dimension so that its upper surface is out of focus with
respect to the lens of the video camera 76 then the support shelf
48 will be adjusted downwardly or upwardly so as to bring the
appropriate surface into focus. Obviously, for efficiency of
inspection of such documents by the medical practitioner from a
remote location, the lens of the video camera 76 is preferably
adjustable to achieve focus from the level of the screen or plate
68 upwardly to a level several inches above the plate 68.
The lower shelf or platform 50 of the mobile emergency center cart
40 is typically fixed relative to the upright structural members 44
and provides support for various communications and power terminals
78 and 80. One or both of these communication and power terminals
will be connected to umbilical cord 42. The communication and power
terminals provide electrical power for operation of video and
lighting equipment on the cart and also to provide for transmission
of control signals from the controller unit operated by the medical
practitioner through the communications link to provide for
selective control of cart mounted video-conferencing apparatus.
Referring again now to FIG. 1, to illustrate the method of the
invention, the medical practitioner 24 manipulates the controller
device 26, which may be a handheld controller as shown or a
controller console resting on a desk of the central office
facility. By manipulating the controller unit the medical
practitioner is enabled to select a desired communications link,
via the communications link circuit 30, with a particular one of
the emergency center facilities 32-34. The controller may also be
selectively manipulated to establish simultaneous communications
with each of the emergency room facilities if audio and video
communications is needed with two or more of the emergency room
facilities at any given time, as described below. Since the
video-conferencing video camera 62 is positioned substantially at
eye level with respect to the medical personnel 38 standing in the
emergency room, the medical practitioner 24 is enabled to insure
efficient interactive audio and video communication with the local
medical personnel of the emergency room facility. This ensures that
the information received by the medical practitioner by both video
and audio is of the best possible quality. For inspection of the
condition of the patient lying on the bed 36 by the medical
practitioner at the central office location, the medical
practitioner manipulates the electronic controller 26 to thereby
adjust the position of the video camera 62 so that the patient or
any selective part of the patient's anatomy can be visually
inspected by the medical practitioner via the interactive
communications link. The audio system of the emergency center cart
40 will also be capable of adjustment from the standpoint of volume
by appropriate manipulation of the electronic controller 26 by the
medical practitioner 24 so that the practitioner is enabled to
communicate directly with the patient in the event the patient is
capable of reporting his or her condition.
After the medical practitioner has diagnosed the patient's
condition treatment of the condition can be published by the
medical personnel 38 located at the emergency room facility. Since
the EC cart 40 is provided with casters or other types of wheels 82
and is thus mobile, the medical personnel and the emergency room
facility will be capable of moving the EC cart to a location that
is desired by the medical practitioner 24 so that the best possible
inspection of the patient may be accomplished. The umbilical cord
42 of the mobile EC 40 will be of sufficient length and flexibility
that the EC 40 may be located virtually anywhere within the
emergency room 32 . . . 34. Also, when treatment is in progress by
the emergency room personnel 38, the medical practitioner 24 can
inspect the treatment during its progress and thus insure that
optimum professional medical treatment is being accomplished. FIG.
4 also illustrates that a nurse 38 can remotely control functions
of the transmitting, receiving and processing unit 60.
Referring now to FIG. 5 a medical video-conferencing system is
shown generally at 84 having a plurality of emergency center rooms
86, 88 and 90, (preferably up to five emergency center rooms) which
may be remotely located from one another, such as in different
parts of a city or in different locations within a geographical
region. The emergency facilities are each provided with a mobile
emergency video-conferencing emergency center cart (EC cart), one
being shown at 92, to enable a patient to be visually and audibly
evaluated and to enable nursing personnel of the emergency room to
be in visual and audible communication with a medical practitioner.
Each of the emergency room facilities is connected via a
communications link 94, 96 and 98 to a telecommunications hub 100
and a central video-communications facility 102 which is in
communication with the telecommunications hub 100 via a
communications link 104. Within the central medical facility 102 is
located a plurality of video monitors 106, 108 and 110 which may be
simultaneously inspected by a medical practitioner 112 so that
video and audio signals from the emergency center room facilities
86, 88, 90 can be simultaneously or selectively evaluated as
needed. The medical practitioner is provided with a control unit
114 for controlling operations, panning and zooming of the video
cameras and lenses of the mobile emergency center carts as desired
for careful, direct evaluation of the patient and also of the
nursing personnel and health care procedures for efficient and
accurate diagnosis of the condition of the patient and inspecting
treatment of the patient as instructed by the medical
practitioner.
It should be understood that the communications links 94, 96, 98
and 104, shown in FIG. 5, may be hardwired electronic connections
or may conveniently take any suitable form of telemetry enabling
video and audio signal transmission to and from the emergency
center facilities and enabling transmission of control signals to
the EC carts of the individual emergency center facilities.
Referring now to FIG. 6, a perspective view is shown of one of the
emergency room facilities of FIG. 5 which shows a patient 116 in a
bed 118, being attended by medical personnel 120, such as a nurse
practitioner, and further showing an EC cart 122 of the general
character shown at 40 in FIG. 2. The EC cart 122, which is shown in
greater detail in FIGS. 6-10, has a frame structure shown generally
at 124 having a bottom shelf 126, an intermediate shelf 128 and an
upper shelf 130. A video monitor 132 and a video-teleconferencing
unit 134 are supported by the upper support shelf 130. The frame
structure of the EC cart 122 is defined by four corner standards or
posts 136 which provide support for the upper, intermediate and
lower support shelves and also define structure to which casters or
other types of wheels 138 are attached. It should be noted that the
corner standards or posts 136 are of sufficient height to extend at
least to or beyond the upper portion of the video monitor 132 to
thus provide the monitor and the video-conferencing unit 134 with
protection against being bumped by other objects within the
emergency center room as the cart is moved or as other objects are
moved. The corner posts also provide cart structure that can be
grasped, pulled or pushed by medical personnel to change the
position of the cart within the emergency center as directed by the
medical practitioner. A document lighting device 140 (FIG. 7), of
the character shown at 64 in FIG. 2, is supported by the
intermediate support shelf 128 and may include a video camera
support 142 supporting a video camera 144 in position for viewing
documents positioned on the support and backlighting screen 146 of
the document lighting device.
To provide the apparatus supported by the EC cart 122 with
additional protection against bumping into, being bumped by or
being jarred by other objects, the posts 136 of the cart are
provided with resilient bumper elements 148 which may be composed
of rubber or any suitable rubber-like material.
The video-teleconferencing unit 134 is provided with a video camera
head 152 which is capable of being controllably tilted upwardly,
downwardly and to each side for the purpose of permitting the
medical practitioner to achieve video inspection of the patient and
other aspects of the emergency center facility as well as having
the capability of zooming the lens of the video-conferencing camera
so that close inspection of any selected anatomy of the patient can
be selectively viewed under the control of the medical practitioner
by electronic signals transmitted from the controller unit via the
communications link to one or more of the selected
video-conferencing systems of the mobile EC carts.
The various electrical contacts or receptacles of the
video-conferencing units 134 are connected by the electronic
circuit wires 154 of the umbilical cable 156 as illustrated by FIG.
8. These electronic conductors are sheathed by plastic tubing 158
for protection thereof.
The lower support shelf 126 of the cart structure functions as a
communications shelf for supporting various communications devices
such as an IMUX inverse multiplexer 160, NT-3 power supply 162,
surge protector 164, and may also support other electrical
equipment such as spare electronic and video cables that may be
needed.
Referring now to FIG. 12, the perspective view shows the mobile EC
cart 122 being located within an emergency center facility. Since
an umbilical cable of the mobile EC cart may extend across a floor
and represent a hazard to persons walking in the immediate area, it
is desirable to provide the emergency center facility with means
for supporting the umbilical cable without diminishing the mobility
of the cart. An overhead track 166 is secured to the ceiling of the
room and may extend around corners as shown at 168. A plurality of
plastic, preferably Nylon rollers 170 are movably received by the
overhead track and are each provided with a hook element 172 for
support of a guided cable 174 representing the umbilical cable of
the cart 122. The guided cable 174 may additionally be supported by
an elastic bungie cord 176 which assists in permitting extension
and controls contraction of the umbilical cable as need for
selective positioning of the cart within the emergency center.
Additionally, one of the support posts of the EC cart may save as a
guide post 178 which receives the power and video-conferencing
control cable 174 to ensure efficient positioning thereof so that
it does not interfere with personnel movement about the mobile EC
cart 122.
As mentioned above, in the central medical facility 102 the medical
practitioner 112 is provided with a plurality of video monitors,
typically one for each of the remote emergency center facilities
86, 88, 90, etc. The control unit 114 utilized by the medical
practitioner typically operates by infra-red (IR) beam transmission
for sending control signals to the video camera and remote control
signal receiver/transmitter 18 shown in FIG. 1. To insure that the
IR signal beam is received by the video camera and remote control
signal receiver/transmitter of a selected one of the plurality of
video-conferencing systems 106, 108, 110, etc. monitored by the
medical practitioner 112 as shown in FIG. 5, it is desirable to
provide the video-conferencing remote control unit 114 with means
for ensuring that the IR signal beam is sufficiently concentrated
to actuate only the remote control signal receiver/transmitter that
is individually selected by the medical practitioner. To ensure
that the IR beam emitted from the video-conferencing remote control
unit 114, an adapter funnel 180 is secured to the remote control
unit in any suitable fashion, such as by means of small screws, by
a suitable bonding agent, etc. The adapter funnel is of tubular
form and defines a small end 182 that is fixed to the remote
control unit 114 and tapers gradually to a larger end 184. The
small end 182 may have a dimension of about 3 mm for intimate
engagement with the transmitting end of the remote control unit. In
contrast, the larger end 184 may have a dimension of about 31/2 mm.
The adapter funnel structure may be defined by a plurality of
substantially flat panels, including upper and lower panels 186 and
188 and side panels 190 and 192. The adapter funnel may be in the
order of 10 inches in length or of any other suitable length that
is sufficient for suitably controlling the dimension of the emitted
IR signal beam in relation to the distance from and location of the
plurality of video-conferencing systems being controlled by the
medical practitioner.
In view of the foregoing it is evident that the present invention
is one well adapted to attain all of the objects and features
hereinabove set forth, together with other objects and features
which are inherent in the apparatus disclosed herein.
As will be readily apparent to those skilled in the art, the
present invention may easily be produced in other specific forms
without departing from its spirit or essential characteristics. The
present embodiment is, therefore, to be considered as merely
illustrative and not restrictive, of the scope of the
invention.
