Bluetooth Based Wireless Digital Stethoscope with Mobile Integration

Abstract

Abstract Acoustic stethoscopes operate on the transmission of sound from the chest piece, via air-filled hollow tubes, to the listener's ears. In the stethoscope, the chest piece and the connecting cable are known to facilitate transmission of pathogens from patient to patient and from patient to the user. Replacing the connecting cable with a wireless system may help reduce the potential risk and further allow broadcasting of the signals to multi-user for examination. So, we present a wireless stethoscope design with mobile integration that transmits heart sounds to mobile devices for evaluation and analysis, thus, eliminates the connecting tube. In this project, the chest-piece of the traditional stethoscope is integrated with micro-controller unit and Bluetooth communication device. Captured signals are processed and transmitted wireless to a mobile device with interface application software for recording, listening and visual display of wave forms . This system may serve as the means for monitoring patients from remote locations and can also be useful for training health personnel through broadcasting of recorded signals for analysis and evaluation by members of a medical team.
