Design and implementation of digital tele stethoscope

Our project relates to Tele-stethoscope which is specially designed to provide state of art technology to medical and health professionals to provide best possible practices to the seniors, people with disabilities, and people in distant areas who may have difficulties to grab a proper health care facility. Initial stage of this project was to consult our professors, health professionals and sketch a concept design. Even though, electronic stethoscopes are available in market but they are out of reach of a common man. We revisited the cost and put up a cost analysis which has turned this instrument more economical. Research was completed to identity the frequencies of head sound which stethoscope needed to filter. The concept includes all the attributes that a Tele-stethoscope should include. Next step was to design analog circuit which comprises pre-amp and post amp stages and then the interfaced to Pc via a free open source. Project was then tested with the help of Skype voice call messenger and we successfully transmitted cardiac sounds with such high quality and precision.
