Abstract

An interactive communication system (400) includes a plurality of in-room video communications system (1250) each including an audio microphone (460), a video camera (440), an audio speaker (470), a patient operated control (420) and a television/video monitor (430). The message sender, e.g. a medical professional, enters a request to contact a selected patient at a terminal (190). A hierarchical access control (130, 135) arbitrates among persons trying to reach a patient based on an accesses hierarchy (200). The requester with the highest role in the hierarchy establishes a video communication link with the patient and appears on the television monitor (430) in place of previously viewed video entertainment.

Claims

1. An interactive communications system comprising:

a plurality of in-room video communications systems, each in-room video communication system including a video monitor, a video camera, a microphone, and an audio speaker associated with a patient;

a video selection unit which supplies video entertainment and video communications to each of the in-room systems; and

a hierarchal access control unit which automatically arbitrates among the video entertainment and video communications based on a defined access hierarchy;

wherein the defined access hierarchy is adjusted based on vital signs of a patient measured by a physiological monitor.

2. The interactive communication system according to claim 1 wherein the hierarchal access control unit includes:

a data entry terminal through which the access hierarchy is entered or modified;

a database which stores the entered access hierarchy;

a server which selects among competing video communications and entertainment based on the entered access hierarchy; and

wherein the video selection unit connects the video communication or entertainment with each in-room video communication system.

3. The interactive communication system according to claim 2, wherein the access hierarchy contains at least one of a primary care physician role, an on-duty physician role, a specialist physician role, a nurse role, a patient role, a guardian role, an attorney role, a friend role, a relative role, and business associate role.

4. The interactive communication system according to claim 1, wherein the video selection unit is connected with a television or cable source, video telephone feed, and a hospital network.

5. The interactive communication system according to claim 1, wherein each in-room video communications system includes a patient control unit such as a keyboard or remote.

6. The interactive communication system according to claim 1, further including:

a hospital database which stores archived images and patient data.

7. The interactive communication system according to claim 6, further including:

a plurality of terminals for medical professionals connected to the video selection unit,

the video selection unit being controllable to establish a video conference call between one of the medical professionals terminals and a selected one of the in-room video communications systems.

8. The interactive communication system according to claim 7, further including a video processor which enables the medical professional terminal to send a split screen image with the medical professional in one section, an image, and a pointer controlled via the medical professional terminal.

9. The interactive communication system according to claim 1, wherein the access hierarchy is dynamically adjustable.

10. The interactive communication system according to claim 9, wherein the access hierarchy is temporally adjustable in accordance with a clock.

11. The interactive communication system according to claim 9, wherein the access hierarchy is patient condition adjustable in accordance with vital signs measured by a physiological monitor.

12. An interactive communication method for providing an in-room audio and video communications, the method comprising:

entering data related to a patient admitted to hospital;

establishing an access hierarchy including at least one of a system administrator role, a primary care physician role, and a patient role;

consulting the access hierarchy via a hierarchical access control unit to automatically arbitrate among persons requesting video communications access to the patient and video entertainment;

establishing a video communications link from a requesting person to an in-room video communications system including a camera, a microphone, a television monitor, a patient operated control, and an audio speaker;

wherein the access hierarchy is adjusted based on vital signs of a patient measured by a physiological monitor.

13. The interactive communication method according to claim 12, further including:

sending a request by a sender to contact a receiver using a computer operable input device;

checking addresses of the sender and the patient against the access hierarchy in the hierarchical access control unit;

if the sender is not authorized to contact the patient, sending denial message to the sender;

if the sender is authorized to contact the patient and if no sender with a higher role in the access hierarchy is competing to reach the patient, establishing a video communication channel between the sender and the patient.

14. The interactive communication method according to claim 12, further including:

with a patient control device, changing the access hierarchy and selecting among video entertainment and video communications.

15. The interactive communication method according to claim 12, further including:

from a medical professional terminal, establishing a video communication link including overriding access requests by persons with a lower role in the access hierarchy.

16. The interactive communication method according to claim 15, further including:

from the medical professional terminal, retrieving images or physiological data from a hospital database;

creating a split screen format in which a video image appears in one section and a video display based on the retrieved images and physiological data appears in another section.

17. The interactive communication method according to claim 16, further including:

moving a pointer on at least the video display controlled by the medical professional terminal or the patient control.

18. The interactive communication method according to claim 12, wherein the access hierarchy includes a plurality of roles in a hierarchy including a system administrator role, the primary care physician role, an on duty physician role, a specialist physician role, a nurse role, a patient role, at least one of a friends role a relative role, and a business associates role.

19. An interactive communication method for providing an in-room audio and video communications, the method comprising:

entering data related to a patient admitted to hospital;

establishing a permissions hierarchy including at least one of a system administrator role, a primary care physician role, and a patient role;

consulting the permissions hierarchy via a hierarchical access control unit to automatically arbitrate among persons requesting video communications access to the patient and video entertainment;

establishing a video communications link from a requesting person to an in-room video communications system including a camera, a microphone, a television monitor, a patient operated control, and an audio speaker

adjusting the permissions hierarchy in accordance with vital signs measured by a physiological monitor.
