Moze COE, Balewadi, Pune, India Abstract: Telemedicine is widely considered to be part of the inevitable future of the modern practice of medicine. It is gaining more and more momentum as a new approach for patient’s surveillance outside of hospitals (at home). Nowadays people are more aware of the health conditions. This proposed system tests the health conditions of an individual by measuring his/her blood pressures, heart rate and temperature using Blood pressure monitor device, Heart beat sensor, Temperature sensor respectively. Monitoring health parameters get display on LCD, and if these monitoring parameters enter in critical section then these parameters send through an alert SMS. SMS can be transmitted using the GSM technology to the doctor and advises can be sought for saving the life of the patient. Keywords: GSM, ARM, LCD, BP monitoring device, heart beat sensor, temperature sensor. I. INTRODUCTION According to estimate, given by the World Health Organization (WHO), cardiovascular disease kills almost seventeen million people around the globe each year along with twenty million people at a risk of sudden heart failure. Some of these lives can often be saved if acute care and surgery is provided within the so-called golden hour. So the need for advice on first hand medical attention and promotion of good health by patient monitoring and follow-up becomes inevitable. Hence, patients who are at risk require that their cardiac health and BP level to be monitored frequently whether they are indoors or outdoors so that emergency treatment is possible. This project is developed for the Doctors to test the heart rate, temperature and blood pressure of the patient. If anything strange inform the doctor through SMS. When patient measures their body parameters, it gets displayed on LCD using ARM7. If the parameter value is below or above a certain range, ARM7 sends signal to the GSM controlling circuit. The GSM unit sends SMS to the Doctor. The mobile of doctor receives the SMS and accordingly displays the status of the heartbeat, blood pressure and temperature. We describe a telemedicine system based on mobile messaging service namely: Short Messaging Service (SMS), which is an integral part of the original 2G GSM cellular system and subsequent generations since all new phones are SMS capable. II. SYSTEM ARCHITECTURE The proposed BP level, heart rate, Body temperature Tele-Alert system is shown in figure 1 our model consists of cuff in which air is pumped through motor, then the pressure sensor senses the body blood pressure. Temperature sensor senses the Body temperature. Heart rate device senses the heart rate from the fingertip using IR reflection method this signal then given to operational amplifier that picks up the bio signal and given to ARM 7. Inbuilt ADC digitizes the analog signal coming from monitoring devices; the digitized signal is simultaneously given to LCD and GSM MODEM. GSM modem forwards the health checkup report to doctor’s mobile using 2G technology.
