Abstract

A system and method that 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 the system and method determine whether an individual who has entered the room of a patient has wash 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.

electronically transmitting an alert or notification to a centralized monitoring system by the computerized monitoring system when the computerized monitoring system determines that the individual did not wash his or her hands.

2. The method for detecting of claim 1 further comprising the step of updating a database in communication with the computerized monitoring system regarding the determination that the individual did not wash his or her hands prior to being within the certain distance from the area or having entered the area.

3. The method for detecting of claim 1 further comprising the step of notifying a previously designated caregiver by electronic message regarding the determination that the individual did not wash his or her hands prior to being within a certain distance from the area or having entered the area.

4. The method for detecting of claim 1 wherein electronically configuring the virtual patient zone comprises the steps of:

receiving a selection of a patient zone from a choice of icons appearing on a screen of a display where the live video feed from the one or more 3D motion and sound sensors is visible on the screen;

receiving a selection of an end point indicating where the patient zone begins;

receiving an indication of a corner point for the patient zone; and

receiving additional indications for remaining corner points for the patient zone to complete the virtual patient zone.

5. The method for detecting of claim 4 further comprising the step of displaying a depth range box.

6. The method for detecting of claim 5 wherein the depth range box is displayed on the screen within a portion of the completed virtual patient zone.

7. The method for detecting of claim 1 further comprising the step of continuously displaying a live video feed of the monitored area received from the one or more 3D motion and sound sensors on a centralized monitoring primary display that is remotely located from the monitored area.

8. The method for detecting of claim 1 further comprising the step of continuously displaying a live video feed of the monitored area for the room received from the one or more 3D motion and sound sensors on a centralized monitoring alert display after it has been determined that the individual in the room did not wash his or her hands.

9. The method for detecting of claim 1 wherein the one or more 3D motion and sound sensors are programmed to lock on the patient and forward data to the computerized monitoring system representing 3D coordinates of body joints for the patient and a general skeletal outline of the monitored individual such that, as the patient moves within a viewing range of the one or more 3D motion and sound sensors, the configured virtual patient zone is virtually moved by the computerized monitoring system so that the virtual patient zone remains around the patient based on the patient'"'"'s current location within the room.

10. The method for detecting of claim 9 wherein the computerized monitoring system determines if the individual is within a certain distance of the patient zone or within the patient zone by the location of specific body segments of the individual being within a certain predetermined or preconfigured distance from the patient zone or located in the virtual patient zone.

11. A computerized method for detecting when an individual who enters a room of a patient washes his or her hands prior to approaching the patient, said method comprising the steps of:

electronically configuring a virtual patient zone defining an area around a patient who is located within a room, the virtual patient zone further configured to follow the patient as the patient moves around the room;

providing one or more 3D motion and sound sensors to capture live video data from the area;

electronically forwarding the video data from the one or more 3D motion and sound sensors to a computerized monitoring system located within the room;

determining by the computerized monitoring system from the received video data when an individual is a certain distance from the area or has entered the area by a location of specific body segments of the individual being within a certain predetermined distance from the virtual patient zone or located in the virtual patient zone;

determining by the computerized monitoring system from the received video data whether the individual washed his or her hands after it is determined that the individual is within the certain distance from the area or has entered the area; and
