Digital Stethoscope for Heart Sounds
نویسندگان
چکیده
The stethoscope has been used for many years, and has been very effective to diagnose certain cardiologic and pulmonologic sounds. For many years healthcare professionals would listen quietly to patients internal organs so they could diagnose from specific sounds of such internal organs. The objective is to develop a Peripheral Interface Controller based digital Stethoscope to capture the heart sound. The proposed designed device consists of following hardware stages: Front-end pickup circuitry, PIC18F2550 microcontroller, (128×64) graphic LCD and a Serial EEPROM. The captured data can be sent to PC for software analysis using LabVEIW. A digital stethoscope would help healthcare professional record their findings on a Serial EEPROM. Once the data is stored, the healthcare professionals can hear and plot the graph. This would be quick and more effective since there is a visual and audio representation to diagnose such cardiologic sounds.
