Abstract
A device for detecting physiological sounds includes a thin film and a conductive element for conducting sounds to the thin film when contacting a skin of a live being. The conductive element is located on the thin film. The device of the invention can significantly improve the detection sensitivity and resolution of physiological sounds, and can give early diagnosis pathological sounds, for example, heart failure can be detected by means of heart sound diagnosis.
Claims20
A device for detecting physiological sounds, the device comprising:
