Abstract

The present invention describes a contact type electronic stethoscope with a noise interference resisting function for auscultation, and the stethoscope includes a chest piece for contacting a patient'"'"'s body, a contact type microphone installed in the chest piece for receiving sounds of patient'"'"'s organs, and an elastic member disposed on an external side of the contact type microphone, so that harsh sounds and irrelevant noises produced by rubbing the surface of clothes with the patient'"'"'s body can be avoided during an auscultation, if the piece chest is pressed and contacted with the patient'"'"'s body without reaching a predetermined pressure and maintains a predetermined distance from the patient'"'"'s body.

Claims

1. A contact type electronic stethoscope with a noise interference resisting function for auscultation, comprising:

a chest piece, disposed on said stethoscope at a position in contact with a patent'"'"'s body;

a contact type microphone, installed in the middle of said chest piece;

an elastic member, installed at an external side of said contact type microphone; and

a circuit board, electrically coupled with said contact type microphone;

thereby when said elastic member is pressed by an appropriate pressure to produce a deformation, said contact type microphone is in contact with said patent'"'"'s body to receive a physiological sound produced by a patient'"'"'s organ.

2. The contact type electronic stethoscope with a noise interference resisting function for auscultation of claim 1, wherein said contact type microphone is pushed out or withdrawn by controlling a press button.

3. The contact type electronic stethoscope with a noise interference resisting function for auscultation of claim 1, wherein said stethoscope comprises a display disposed on an external side said stethoscope for displaying a detected signal.

4. The contact type electronic stethoscope with a noise interference resisting function for auscultation of claim 2, wherein said stethoscope comprises a display disposed on an external side said stethoscope for displaying a detected signal.

5. The contact type electronic stethoscope with a noise interference resisting function for auscultation of claim 1, wherein said circuit board comprise a transmission circuit for a wireless transmission.

6. The contact type electronic stethoscope with a noise interference resisting function for auscultation of claim 2, wherein said circuit board comprise a transmission circuit for a wireless transmission.

7. The contact type electronic stethoscope with a noise interference resisting function for auscultation of claim 1, wherein said circuit board comprises a control circuit for adjusting the volume of an output sound

8. The contact type electronic stethoscope with a noise interference resisting function for auscultation of claim 2, wherein said circuit board comprises a control circuit for adjusting the volume of an output sound.
