Development of a Portable GSM SMS-Based Patient Monitoring System for Healthcare Applications
Although health care is a vital problem, in recent years mobile communication has become a widespread part and parcel of everyday life even in the rural areas of developing countries. This paper proposed a model to include the mobile communication for monitoring vital signs of health such as blood pressure, heart rate, body temperature; blood glucose level and sends result as Short Message Service (SMS) for the physician so as to monitor their patients continuously. Cuffless pressure sensing transducer is taken into consideration to measure pressure pulse and then combined with oscillometric method to measure Blood Pressure (BP). Availability of different sensors and measurement techniques to determine heart rate is presented. Conventional glucometry in low cost electronics and body temperature measurement using electronic thermistor is also described here. Sensed parameters are processed and stored into an array in ARM7 processor and sent via GSM SIM300 Modem. This portable vital sensing system is useful to analyze daily health condition; can be used both in home and hospital to prevent Hypertension, Heart Attack and to control Diabetes.
