Wireless Auscultation

Auscultation is the act of listening to internal body sounds as a part of making a medical diagnosis. During auscultation, health care providers routinely listen to a patient’s lungs, heart, or intestines and they evaluate the frequency, intensity, duration, number, and quality of the sounds that they hear. Traditionally, auscultation has always been done with a stethoscope, however there are some drawbacks to this method. Stethoscopes require a doctor to be tethered to the patient and sounds can only be monitored intermittently.

Therefore, our project goal is to develop a wireless and hands free auscultation device that will continuously monitor heart and lung sounds. Our design will consist of a battery to power the device, an audio pick up source, an amplification and filtering unit, an analog to digital converter, and a Bluetooth transmitter.
