BACKGROUND OF THE INVENTION1. 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 INVENTIONIt 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.
So that the manner in which the above recited features, advantages and objects of the present invention are attained and can be understood in detail, a more particular description of the invention, briefly summarized above, may be had by reference to the preferred embodiment thereof which is illustrated in the appended drawings, which drawings are incorporated as a part hereof. It is to be noted however, that the appended drawings illustrate only a typical embodiment of this invention and are therefore not to be considered limiting of its scope, for the invention may admit to other equally effective equivalent embodiments.
In the Drawings:
Referring now to the drawings and first to
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
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
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
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.
