Autonomous Human Motion Monitoring System using Wireless Body-worn Sensors    

System for autonomously monitoring body motion of patients in a medical or related facility (nursing home, hospital, etc). Body-worn motion and pressure sensors wirelessly transmit data to a network

Overview

Falls are unfortunate events, which aggravate the risk for disability and mortality among the elderly. Statistics show that fall events occur on a regular basis within the elderly community. About one third of the elder population over the age of 65 falls each year. In 2008, more than 2.11 million elderly people (age 65+) were treated for non-fatal falls. Injuries due to these fall events are often non-fatal in the short term. However the direct medical cost for these injuries, fatal or not, has been shown as high as 10K. Fall Detection can lead to rapid emergency response, faster medical attention and therefore, quicker recovery and a point of reference to determine the cause of the falls. Therefore a low cost, scalable, easily installable, 24/7 fall detection system is necessary and such a system has been developed.

The autonomous geriatric fall detection system technology is a form of fall detection that not only detects when a fall has occurred but could also prevent falls with the evaluation of collected data. The technology is intended for medical facilities such as nursing homes, hospitals, and other facilities in the related field. The technology will provide users with immediate intervention since caregivers are alerted as the falls happens which will eventually lead to a reduction in medical cost. The technology motion sensors can be built into shoes, belts, and other clothing items so that the users are unaffected by the presence of the sensors.

The basis of this systems consist of microsized sensors integrated with wireless platforms. The end goal of evaluating fall events in mind, the sensors used by these platforms include accelerometers, pressure sensors, gyroscopes, pulse oximeters, heart rate monitors, and infrared technology. Our system has shown that several types of sensors used in tandem may provide automatic and real-time evaluation of the patient status

While this technology is not currently patented, there is still an opportunity to file for IP.

How the Technology Solves the Problem

A patient will wear the belt and the slippers. If a fall event occurs or if a patient is at a risk of falling, the body worn sensors will transmit data via TCP to a computer for data parsing. The GUI will read the TCP data from the gateway, organize the information and store the data for future analysis. Due to commitment to open communication of data, the GUI also will send the raw data to AT&T Labs Research for auxiliary storage and corroboratory analysis.

In addition to the storage of data, the GUI will also provide immediate feedback for medical personnel. The GUI displays selected patient gait data in real-time in order to determine fall events. Fall events are defined by the algorithm as data that shows a subject in immediate risk of falling or has already possibly fell. If a fall event occurs for a patient being monitored by the system, both visual and audio alarms are generated by the GUI such that medical personnel will respond within moments, and possibly provide lifesaving first aid.
