Monitoring the patient's condition can be done by using biomedical telemetry method where there is a mobile communication between microcontrollers. The temperature, heart beat and blood pressure are all sensed by using the appropriate sensors which are placed near the patient's body that is under investigation.
The biomedical telemetry system consists of temperature sensor, heart beat sensor, pressure sensor, A/D converter, signal conditioning circuit, microcontroller, data cable, mobile phone, LCD display.
The temperature sensor is used to sense the temperature value of the patient's body .The sensed output is given to A/D converter where the analog signal is converted to digital signal. The digital output is given to microcontroller.
The microcontroller delivers the signal for mobile phone through data cable. Then the signal is transmitted to other mobile through GSM network. The receiver mobile receives the signal and it is given for a PC. The signal from data cable is given to PC and the value gets displayed using monitor.
The pressure sensor is used to sense the pressure value of the patient's body .The sensed output is given to A/D converter where the analog signal is converted to digital signal. The digital output is given to microcontroller.
The microcontroller delivers the signal for mobile phone through data cable. Then the signal is transmitted to other mobile through GSM network. The receiver mobile receives the signal and it is given for a PC. The signal from data cable is given to PC and the value gets displayed using monitor.
Heart beat can be sensed by using heart beat sensor which is then given to a signal conditioning circuit. This unit delivers a train of pulses to microcontroller and the value gets displayed using LCD display.
