METHODS AND SYSTEMS FOR MONITORING AND PREVENTING PRESSURE ULCERS
First Claim
1. A method of monitoring pressure applied to a pressure sensitive area of a human body, the method comprising:
- contacting a plurality of pressure sensors with pressure sensitive areas of the human body;
determining body posture;
tracking and determining the position of limbs of the human body;
collecting data from the pressure sensors mounted on a bed'"'"'s surface such as a pressure sensor mat;
extracting features from the collected data;
training a model by using the extracted features; and
determining the level of risk associated with the development of a pressure ulcer.

Abstract
The present invention relates generally to the prevention and treatment of pressure ulcers and a platform for monitoring, prevention and management of pressure ulcer using a pressure mapping system that records a patient'"'"'s bed posture, tracks different limbs along with associated statistical pressure image data and produces a summary report for care givers after data analysis and risk assessment. The methodology allows care givers to utilize the stress data and schedule the repositioning of the patient more effectively. The invention relates to creation and using algorithms and analytics for monitoring, prevention and management of pressure ulcers which include time-stamped whole-body pressure distribution data collection and profiling; posture classification, limb detection and tracking; quality of turn and risk assessment; turning schedule and nursing staff utilization for pressure ulcer management; and patient status reporting system customized for caregivers.

16. A method for monitoring, prevention and management of pressure ulcers of a patient, the method comprising:
- acquiring at least one real-time physiological data stream;
identifying a physiological data related to pressure present in the at least one real-time physiological data stream;
selecting a first algorithm directed to produce a first diagnostic interpretation of the physiological data;
selecting a second algorithm directed to produce a second diagnostic interpretation of the physiological data, wherein the first algorithm and the second algorithm produce diagnostic interpretations of the same identified physiological data;
applying the first algorithm to the at least one real-time physiological data stream as the at least one real-time physiological data stream is acquired to produce at least one first diagnostic interpretation;applying the second algorithm to the at least one real-time physiological data stream as the at least one real-time physiological data stream is acquired to produce at least one second diagnostic interpretation; and
displaying the first and second diagnostic interpretations. - View Dependent Claims (17, 18, 19, 20)
