Design of Wireless Electronic Stethoscope Based on Zigbee

The auscultation of heart sounds is an important method of diagnosing disease.In this paper,we discuss the application of electronic stethoscope designed with the wireless transmission technology,based on embedded processor.Data can be transmitted through the Zigbee wireless transmission module,using a microphone receiving the voice of the heart.It can be insert the capacitor microphone in the acoustic stethoscope head to turn it into digital stethoscope,in order to receive the sound through the headset.The heart sound signals will be processed and amplified.The system of heart sounds achieves signal sampling,processing and wireless dispatch,so that several doctors can do the consultation.
