Abstract

The local surveillance sub-system recognizes that a patient medical procedure has or will soon commence by sensing the presence of a healthcare professional in or near the surveillance area, and in response, creates a separate patient medical procedure A/V file for the surveillance data that will be captured. A dedicated procedure remote may be provided for receiving manual interactions from HC professionals present for a procedure or, alternatively, the local surveillance sub-system may autonomously interact with a personal security token device possessed by the HC professional. A procedure data file is also created that holds all of the pertinent information concerning the procedure that is known by the local surveillance sub-system. The patient procedure surveillance A/V file is given a higher priority than ordinary surveillance data captured by the local surveillance sub-system and is then copied to a nonvolatile memory that is separate from the primary memory of the surveillance sub-system. The local surveillance sub-system captures surveillance A/V data that is copied to the nonvolatile memory until the system senses that the procedure has ended, when an end-of-procedure message is transmitted across the HCF distribution network. The corresponding patient medical procedure surveillance A/V file resides in a local nonvolatile memory until it can be downloaded to a central storage at the healthcare facility.

Claims

1. A surveillance device for documenting patient procedures comprising:

a surveillance camera for capturing a plurality of video frames of a surveillance area;

a patient procedure remote for detecting the presence of a healthcare professional proximate to the surveillance area and in response, generating a procedure indication; and

a surveillance control device comprising;

a primary nonvolatile memory;

a secondary nonvolatile memory;

medical procedure remote interface for receiving a procedure indication from the patient procedure remote and generating procedure information from the procedure indication;

a video processing unit coupled to the surveillance camera for processing video frames captured by the surveillance camera and storing the processed video frames in the primary nonvolatile memory, and in response to receiving procedure information from the medical procedure remote interface, attaching at least some of the procedure information to the video frames subsequently stored in the primary nonvolatile memory and copying the video frames subsequently stored in the primary nonvolatile memory to the secondary nonvolatile memory;

a network controller coupled to a healthcare facility distribution network for obtaining processed video frames from the primary nonvolatile memory and transmitting the processed video frames across the healthcare facility distribution network; and

wherein the patient procedure remote includes a legacy interface for receiving generic manual interactions from a healthcare professional that may be correlated to a patient procedure.

2. The surveillance device recited in claim 1, wherein the legacy interface includes at least one of a manual actuator, switch, lever, knob, touch pad and button for receiving manual interactions from a healthcare professional.

3. The surveillance device recited in claim 1, wherein the legacy interface includes at least one of a biometric sensor, voice recognizer, fingerprint reader, whole hand scanner, iris/retina recognizer, for receiving biometric interactions from a healthcare professional.

4. The surveillance device recited in claim 1, wherein the legacy interface for receiving generic manual interactions from a healthcare professional includes at least one of a mouse, pointer, trackball, keyboard, touchpad and touch screen.

5. The method recited in claim 4 above, wherein the procedure indication is an identity of a healthcare professional and attaching information related to a patient procedure to each of the plurality of subsequent video frames further comprises:

attaching the identity of the healthcare professional to each of the plurality of subsequent video frames.

6. The surveillance device recited in claim 1, wherein the patient procedure remote is a pillow speaker with a multitasking manual interface for receiving manual interactions from a healthcare professional.

7. The surveillance device recited in claim 1, wherein the patient procedure remote is a hardware token in the possession of a healthcare professional.

8. The surveillance device recited in claim 7, wherein the hardware token is an automated electronic security token comprising one of a transponder key FOB, RFID tag, Bluetooth wireless interface, WIFI interface.

9. The surveillance device recited in claim 1, wherein the primary nonvolatile memory and the secondary nonvolatile memory are separate partitions in a nonvolatile memory.

10. The surveillance device recited in claim 1, wherein the secondary nonvolatile memory is one of a hard drive, optical drive and solid state drive.

11. A method for documenting patient procedures in a surveillance device, where in the surveillance device comprising a surveillance camera, a patient procedure remote, a surveillance control device comprising a primary nonvolatile memory, a secondary nonvolatile memory, a medical procedure remote interface, a video processing unit, a network controller coupled to a healthcare facility distribution network, said method comprising:

receiving a plurality of video frames from the surveillance camera;

storing each of the plurality of video frames in the primary nonvolatile memory;

transmitting the at least some of the video frames across the healthcare facility distribution network;

detecting a presence of a healthcare professional proximate to a surveillance area;

receiving a plurality of subsequent video frames from the surveillance camera;

delineating each of the plurality of subsequent video frames as procedure documentation video frames, the delineating including prioritizing each of the plurality of procedure documentation video frames in the primary nonvolatile memory;

storing the plurality of procedure documentation video frames in the primary nonvolatile memory;

copying the plurality of procedure documentation video frames in the primary nonvolatile memory to the secondary memory; and

transmitting at least some of the plurality of procedure documentation video frames in the primary nonvolatile memory across the healthcare facility distribution network.

12. The method recited in claim 11 above, wherein delineating each of the plurality of subsequent video frames as procedure documentation video frames further comprises attaching information related to a patient procedure to each of the plurality of procedure documentation video frames.

13. The method recited in claim 12 above, wherein delineating each of the plurality of subsequent video frames as procedure documentation video frames further comprises delineating each of a second plurality of video frames stored in the primary nonvolatile memory prior to detecting the presence of a healthcare professional as a procedure documentation video frame.

14. The method recited in claim 12 above, further comprises:

detecting an end to the patient procedure;

gathering information concerning the patient procedure;

enclosing the information concerning the patient procedure in an end-of-procedure message; and

transmitting the end-of-procedure message across the healthcare facility distribution network.

15. The method recited in claim 12 above, wherein detecting a presence of a healthcare professional proximate to a surveillance area further comprises:

receiving a procedure indication from the patient procedure remote.

16. The method recited in claim 12 above, wherein detecting a presence of a healthcare professional proximate to a surveillance area further comprises:

receiving procedure information from the patient procedure remote.

17. The method recited in claim 16 above, wherein attaching information related to a patient procedure to each of the plurality of subsequent video frames further comprises:

attaching the procedure information from the patient procedure remote to each of the plurality of subsequent video frames.

18. The method recited in claim 12 above, wherein the procedure indication is in response to a manual interaction between the healthcare professional and the patient procedure remote.

19. The method recited in claim 12 above, wherein the procedure indication is in response to an automated manual interaction between the healthcare professional and the patient procedure remote.

20. The method recited in claim 12 above, further comprising:

receiving a request for wherein the procedure indication is in response to a manual interaction between the healthcare professional and the patient procedure remote.
