Title:
ELECTRONIC STETHOSCOPE
Document Type and Number:
Japanese Patent JP2022061563
Kind Code:
A
Abstract:
To provide an electronic stethoscope capable of reducing an influence of noise of an ambient environment detected by a sensor element through a person to be auscultated, etc.SOLUTION: A first electrode 5 that can come in contact with a body surface of a person to be auscultated is provided so that a signal detected by the first electrode 5 is superposed on signal wiring which is a predetermined constant potential of a signal processing circuit 3. Furthermore, a second electrode 7 that can come in contact with an auscultator is provided so that a signal detected by a second electrode is superposed on signal wiring which is a predetermined constant potential of the signal processing circuit 3. The potential of the person to be auscultated and the constant potential of the signal processing circuit 3 become the same potential so that an influence of noise can be reduced.SELECTED DRAWING: Figure 3
