Abstract

A user interface and software system and architecture enables linking medical record information and patient location to a camera associated with that location when a particular patient is selected by a clinician using a health information system. The image of the patient as recorded by an in-room camera is displayed within a picture-in-picture display on a large plasma screen located at a command station, for example. The image may be controlled by a remote camera controller employing a Web-based user interface that allows a user to implement a pan-tilt-zoom (PTZ) camera controller via mouse control, for example. Information relating to patient location is used to remotely control, via Web-based application, the selection of the appropriate camera and the type of display in which to show the image. The user interface associated with this architecture provides an efficient and intuitive means of selecting specific images and specific display styles. The system operates in a parent-child relationship in which information associated with a parent application (HIS, for instance) is passed to the application architecture, thereby providing a direct, error-free and positive link to the application.

Claims

1. A remote patient monitoring system for visually monitoring patients in a plurality of different remote locations from a plurality of different locations, comprising:

an input processor for receiving a patient identifier derived from user interaction with an executable application;

at least one repository of mapping information associating patient identifiers with corresponding camera identifiers and room identifiers enabling acquisition of video information from a location associated with a particular patient;

a data processor for using said mapping information for automatically associating a received particular patient identifier with a particular camera identifier and initiating acquisition of video image data of said particular patient from said particular camera, in response to user selection of a displayed image element associated with said particular patient in a display image associated with said executable application and enabling the viewing of a plurality of patients in different locations concurrently from a plurality different remote locations; and

a display processor for initiating generation of data representing a composite display image presenting said video image data of said particular patient in a first image window together with medical information concerning said particular patient in a second image window.

2. A system according to claim 1, including

user interface enabling control of said camera pointing in pan, tilt, and zoom.

3. A system according to claim 2, wherein

said user interface enables real-time control of said camera using a mouse-based interface and a virtual or real mouse pad.

4. A system according to claim 1, wherein

said executable application is at least one of, (a) a hospital information system and (b) a clinical information system and

said display image associated with said executable application provides a list of different patients.

5. A system according to claim 1, wherein

said composite display image employs a default image format.

6. A system according to claim 1, wherein

said composite display image employs an image format determined by a user preference profile.

7. A system according to claim 1, wherein

said composite display image employs an image format selected by said user.

8. A system according to claim 1, wherein

said data processor initiates acquisition of audio data of said particular patient.

9. A system according to claim 1, wherein

said remote patient monitoring system is employs a Web browser compatible user interface.

10. A remote patient monitoring system for visually monitoring patients in a plurality of different remote locations, comprising:

an input processor for receiving a patient identifier derived from user interaction with an executable application;

at least one repository of mapping information associating patient identifiers with corresponding camera identifiers and room identifiers enabling acquisition of video information from a location associated with a particular patient;

a data processor for using said mapping information for automatically associating a received particular patient identifier with a particular camera identifier and initiating acquisition of video image data of said particular patient from said particular camera and initiating acquisition of medical parameter data from a monitoring device coupled to said particular patient, in response to user selection of a displayed image element associated with said particular patient in a display image associated with said executable application; and

a display processor for initiating generation of data representing a composite display image presenting said video image data of said particular patient in a first image window together with said acquired medical parameter data, concerning said particular patient in a second image window.

11. A system according to claim 10, wherein

said data processor automatically stores said video image data of said particular patient in a record associated with said particular patient in response to a predetermined condition.

12. A system according to claim 11, wherein

said predetermined condition comprises at least one of, (a) a patient medical parameter exceeding a predetermined threshold or ranges (b) a combination of a plurality of patient medical parameters exceeding corresponding predetermined thresholds or ranges and (c) user command.

13. A system according to claim 10, wherein

said display processor initiates generation of data representing a composite display image presenting video image data of a plurality of different patients in a corresponding plurality of different image windows.

14. A system according to claim 13, wherein

said plurality of different patients comprise patient assigned to a single care unit.

15. A system according to claim 13, including

a configuration processor enabling a user to graphically select multiple patient or single patient views for presentation in said composite display image.

16. A remote patient monitoring system for visually monitoring patients in a plurality of different remote locations, comprising:

an input processor for receiving a patient identifier automatically provided as context information by an executable application;

at least one repository of mapping information associating patient identifiers with corresponding camera identifiers and room identifiers enabling acquisition of video information from a location associated with a particular patient;

a data processor for using said mapping information for automatically associating a received particular patient identifier with a particular camera identifier and initiating acquisition of video image data of said particular patient from said particular camera, in response to user selection of a displayed image element associated with said particular patient in a display image associated with said executable application; and

a display processor for initiating generation of data representing a composite display image presenting said video image data of said particular patient in a first image window together with medical information concerning said particular patient in a second image window.

17. A system according to claim 16, wherein

said patient identifier is derived in response to user selection of a displayed image element associated with a particular patient identified in a list of a plurality of different patients provided by said executable application.

18. A remote patient monitoring system for visually monitoring patients in a plurality of different remote locations, comprising:

an input processor for receiving a patient identifier derived from user interaction with an executable application;

at least one repository of mapping information associating patient identifiers with corresponding camera identifiers and room identifiers enabling acquisition of video information from a location associated with a particular patient;

a display processor for initiating generation of data representing a two dimensional image display indicating first and second axes and a cursor; and

a camera controller for using said mapping information for automatically associating a received particular patient identifier with a particular camera identifier and remotely initiating movement of a camera associated with said camera identifier in pan and tilt axes in proportion to cursor distance from an origin formed by said first and second axes of said two dimensional image.
