Abstract

A system and method that allows caregivers, central monitoring companies and other persons to monitor whether individuals entering patients'"'"' rooms take appropriate steps to mitigate the spread of healthcare associated infections to the patients receiving healthcare services. In one non-limiting example the system and method determine whether an individual who has entered the room of a patient has washed his or her hands prior to approaching the patient. A live video feed from the monitored rooms can be displayed on a centralized monitoring primary display which can be located remote to the monitored rooms. When it is determined that an individual in a specific room from the monitored rooms is approaching a patient and has not washed his or her hands an alert, notification and/or a live video feed for the specific room can be displayed on a centralized monitoring alert display which can also be preferably located remote to the monitored rooms.

Claims

1-20. -20. (canceled)

21. A computerized method for live video analysis, the computerized method comprising:

receiving live video data of a virtual zone;

determining when at least a portion of an individual is observed in the virtual zone based on the live video data;

based on the live video data of the virtual zone, identifying a specific gesture of the at least a portion of the individual;

determining from the live video data whether the individual is in compliance with the sanitization task based on the specific gesture; and

when it is determined that the individual is in compliance with the sanitization task, transmitting the notification to the individual, wherein the notification indicates that the individual is in compliance with a sanitization task.

22. The method of claim 21, wherein determining from the live video data whether the individual is in compliance with the sanitization task based on the specific gesture comprises determining that the specific gesture corresponds to the sanitization task.

23. The method of claim 21, wherein determining from the live video data whether the individual is in compliance with the sanitization task based on the specific gesture comprises using three-dimensional coordinates of the at least a portion of the individual from the live video data to determine a duration of time during which the at least a portion of the individual remains in the virtual zone.

24. The method of claim 21, wherein the specific gesture of the at least the portion of the individual is the individual rubbing their hands together.

25. The method of claim 21, wherein identifying the specific gesture of the at least the portion of the individual comprises using three-dimensional coordinates of the at least a portion of the individual from the live video data to recognize that the individual rubs their hands together.

26. The method of claim 21, wherein identifying the specific gesture of the at least the portion of the individual comprises using three-dimensional coordinates of the at least a portion of the individual from the live video data to recognize that the individual activates a dispersal of a sanitizing fluid.

27. The method of claim 21, wherein identifying the specific gesture of the at least the portion of the individual comprises using three-dimensional coordinates of one or more joints of the at least a portion of the individual from the live video data to recognize that the individual rubs their hands together.

28. The method of claim 21 further comprising when it is determined that the individual is not in compliance with the sanitization task, transmitting a notification to the individual, wherein the notification indicates that the individual is not in compliance with the sanitization task.

29. One or more non-transitory computer-readable media storing executable instructions thereon for a method of live video analysis, wherein execution of the instructions by one or more processors provides a method, the method comprising:

defining a virtual zone;

receiving live video data of the virtual zone;

determining when hands of an individual are observed in the virtual zone based on the live video data;

based on the live video data of the virtual zone, identifying a specific gesture of the hands of the individual;

determining from the live video data whether the individual is in compliance with the hand sanitization task based on the specific gesture of the hands; and

when it is determined that the individual is in compliance with the hand sanitization task, transmitting a notification to the individual, wherein the notification indicates that the individual is in compliance with the hand sanitization task.

30. The method of claim 29, wherein determining from the live video data whether the individual is in compliance with the hand sanitization task based on the specific gesture comprises determining that the specific gesture corresponds to the hand sanitization task.

31. The method of claim 29, wherein determining from the live video data whether the individual is in compliance with the hand sanitization task based on the specific gesture comprises using three-dimensional coordinates of the at least a portion of the individual from the live video data to determine a duration of time during which the at least a portion of the individual remains in the virtual zone.

32. The method of claim 29, wherein the specific gesture of the hands of the individual is the individual rubbing their hands together.

33. The method of claim 29, wherein the specific gesture of the hands of the individual is the individual activating a dispersal of a sanitizing fluid.

34. The method of claim 29, wherein identifying the specific gesture of the hands of the individual comprises using three-dimensional coordinates of the hands from the live video data to recognize that the individual rubs their hands together.

35. The method of claim 29, wherein identifying the specific gesture of the hands of the individual comprises using three-dimensional coordinates of one or more joints of the hands from the live video data to recognize that the individual rubs their hands together.

36. The method of claim 29 further comprising when it is determined that the individual is in compliance with the hand sanitization task, transmitting the notification to the individual, wherein the notification indicates that the individual is in compliance with the hand sanitization task.

37. The method of claim 29, further comprising continuously displaying the live video data of the virtual zone via a graphical user display.

38. The method of claim 29, wherein the virtual zone corresponds to equipment for performing the hand sanitization task, and wherein the equipment is located in a patient room in a clinical setting.

39. The method of claim 29, wherein the live video data is received from one or more three-dimensional sensors, the one or more three-dimensional sensors capturing at least one of video, audio, or depth.

40. A system for live video analysis, the system comprising:

one or more three-dimensional sensors; and

one or more processors communicatively coupled to the one or more three-dimensional sensors, wherein the one or more processors;

define a virtual zone;

receive live video data of the virtual zone, the live video data received from the one or more three-dimensional sensors;

determine when hands of an individual are observed in the virtual zone based on the live video data;

based on the live video data of the virtual zone, identify a specific gesture of the hands of the individual;

determine from the live video data whether the individual is in compliance with a hand sanitization task based on the specific gesture of the hands; and

when it is determined that the individual is in compliance with the hand sanitization task, transmit a notification to the individual, wherein the notification indicates that the individual is in compliance with the hand sanitization task.
