Advanced Electronic Stethoscope

There has been an exponential increase in health care costs in the last decade. Seniors have to make frequent visits to their doctor to get their vital signs measured. The objective of this paper is to design and implement a reliable, cheap, low powered, non-intrusive, and accurate system that can be worn on a regular basis and monitors the vital signs and displays the output. This data is also easily accessible by the physician through wireless network. This paper specifically deals with the signal conditioning and data acquisition of three vital signs: heart rate, blood pressure, and body temperature. The "ADVANCED ELECTRONIC STETHOSCOPE" is developing to measure the various body parameters using a single stethoscope. The stethoscope comprises of four different wires which perform different tasks. Out of them first is used to measure the heart beat rate, which includes microphone and to hear the beats we are using headphones. Other is used to measure blood pressure which includes the blood pressure sensor. We display the graphical view of blood pressure for measurement on the screen. One of them is made to measure the body temperature which is possible using the temperature sensor which is being displayed on the screen. And the last one, is used to measure the ECG(electrocardiograph). The graph of ECG is being displayed.
