Method and system for determining whether a caregiver takes appropriate measures to prevent patient bedsores
First Claim
1. A computerized method for monitoring compliance with a bedsore-prevention regimen, the method performed by one or more processors and comprising:
- electronically receiving 3D motion sensor data from one or more 3D motion sensors positioned in a room with a patient;
using the 3D motion sensor data to identify a position of the patient in the room;
receiving a configuration of a virtual patient zone, wherein the virtual patient zone is a 3D volume defined by proximity to the patient;
using the 3D motion sensor data to identify a second person in the room;
detecting when the second person enters the virtual patient zone;
timing the duration from the entry of the second person into the virtual patient zone to an exit of the second person from the virtual patient zone; and
identifying a failure to comply with a bedsore-prevention regimen when duration from the entry to the exit is less than a predetermined period of time needed to comply with the bedsore-prevention regimen, wherein the predetermined period of time is configured to be specific to the identified second person.

Abstract
Systems and methods allow caregivers, central monitoring, and/or other persons to monitor whether a patient has moved or changed positions sufficient to prevent the patient from developing bedsores or at least reduce the chance of bedsores from developing. The systems and methods work by detecting when a caregiver has entered within a predefined patient or bed zone. The systems and methods detect whether the caregiver remained within the zone for a predetermined time period. If the caregiver fails to remain within the zone for the predetermined time period, an alert is generated as this could indicate that the caregiver was not present long enough with the patient for the patient to sufficiently move or change positions.

10. A computerized method for monitoring compliance with a bedsore-prevention regimen, the method performed at one or more processors and comprising:
-
obtaining 3D motion data from one or more 3D motion sensors in a room with a patient; identifying the patient within the room from the 3D motion data; receiving a configuration of a virtual patient zone, wherein the virtual patient zone is a 3D volume defined by proximity to the patient; identifying a second person within the room from the 3D motion data; determining when the second person has entered the virtual patient zone; timing a duration during which the second person remains in the virtual patient zone; identifying a failure to comply with a bedsore-prevention regimen when on the duration is less that a predetermined period of time needed to comply with the bedsore-prevention regimen, wherein the predetermined period of time is configured to be specific to the identified second person; and initiating an alert upon identifying the failure to comply with the bedsore-prevention regimen. - View Dependent Claims (11, 12, 13, 14, 15)

16. A system for monitoring compliance with a bedsore-prevention regimen, the system comprising:
-
one or more 3D motion sensors communicatively coupled to a network; a visual display apparatus communicatively coupled to the network and configured to display a visual representation of 3D motion data from the one or more 3D motion sensors; and one or more processors configured to execute computer-readable instructions for performing operations comprising; receiving a configuration of a virtual patient zone, wherein the virtual patient zone is a 3D volume defined by proximity to a first person or object, identifying an entry by a second person into the virtual patient zone, identifying the second person based on one or both of height and distance between points on a body of the second person, determining a duration for which the second person remains in the virtual patient zone after entry, identifying a failure to comply with a bedsore-prevention regimen when the duration is less than a predetermined period of time needed to comply with the bedsore-prevention regimen, wherein the predetermined period of time is configured to be specific to the identified second person; and initiating an alert upon identifying a failure to comply with the bedsore-prevention regimen. - View Dependent Claims (17, 18, 19, 20)
