Describes a prototype wireless health alert system for continuous remote monitoring of elderly patients to detect abnormal conditions and alert caretakers.
Prototype enables home alerts for elderly patients; leaves open validation before any clinical use.
The aim of this prototype wireless health alert system is to monitor the elderly sick patients at home independently and inform during the emergency health conditions to the caretaker automatically and manually by pressing the push button switch fixed in the monitoring system. This system is specially designed with fixed monitoring system on the body. The proposed system consists of sensors, microcontrollers, A/D converter ,signal conditioning circuit, transmitter section and receiver section. Sensors are used to sense temperature pressure, heartbeat rate. In addition to this a push button switch is fixed in the monitoring system to manually send the signal to transmitter A/D converter converts analog signal sensed by sensor into digital signal and fed into signal conditioning circuit. Microcontroller process this signal and send through GPRS/GSM modem Transmitter transmits the sensors signals which is output by microcontroller Receiver section receives the signal and communicates to caretaker mobile. The wireless health alert system is compact and portable. continuous monitoring helps to detect abnormal conditions and avoids delay in treatment and makes fast recovery. This can be implemented in hospitals, homes and homecare centers for aged people.
