International Journal of Distributed and Parallel Systems (IJDPS) Vol.3, No.1, January 2012 DESIGN OF WIRELESS ELECTRONIC STETHOSCOPE BASED ON ZIGBEE Ms. Kadam Patil D. D. and Mr. Shastri R. K. Department of ETC Vidya Pratishthan’s CoE, Baramati, Maharashtra, India kadam.deepali2008@ , rajveer_shastri@ ABSTRACT Heart sound stethoscope is primary stage to access diseases. In this paper design of an electronic stethoscope with the functions of wireless transmission is discussed. This electronic stethoscope based on embedded processor. The data can be transmitted through wireless transmission using Zigbee module. A microphone is used to pick up the sound of the heart beat. Acoustic stethoscope can be changed into a digital stethoscope by inserting an electric capacity microphone into its head. The signal is processed and amplified to play with or without earphone. Heart sounds are processed, sampled and sent wirelessly using Zigbee module so that multiple doctors can do auscultation. PC connectivity is provided through serial port where from audio and video can be made available through LAN and internet for telemedicine consultation. Heart beat signals are sensed, sent, displayed, monitored, stored, reviewed, and analysed with ease. KEY WORDS Electronic stethoscope, Zigbee, Auscultation 1. INTRODUCTION The Stethoscope is an acoustic medical device for listening to internal sounds in human body which is known, in medical terms, as auscultation. Heart sound auscultation is one of the most basic ways to assess the state of the cardiac function [1]. Some researches concluded that an abnormal heart-rate profile during exercise and recovery is a predictor of sudden death.
