Pickup method of stethoscope and stethoscope

Abstract

The embodiment of the invention provides a pickup method of a stethoscope and the stethoscope, and the method comprises the following steps: when an auscultation diaphragm vibrates to drive air in an auscultation head to vibrate, a first sound through a leather hose and a receiver of the stethoscope is picked up; the vibration waveform of vibration of the auscultation diaphragm is collected through the electronic device, and second sound is picked up. According to the scheme, the stethoscope can have a traditional auscultation mode and an electronic auscultation equipment pickup mode at the same time, compared with a second-generation electronic stethoscope in the prior art, the use habit of a doctor can be prevented from being changed, the traditional auscultation mode of the stethoscope can still be used, original sound heard by the traditional auscultation mode serves as a diagnosis basis, and the learning cost of doctors is prevented from being increased; the electronic device is used for collecting the vibration waveform of the vibration of the auscultation diaphragm to pick up sound instead of picking up sound based on air vibration, and compared with a first-generation electronic stethoscope in the prior art, interference such as echo, external noise and speaking sound can be avoided or reduced, and the pickup effect can be improved.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a method for picking up sound by a stethoscope and the stethoscope. Background technique [0002] The auscultation head of a traditional mechanical stethoscope has an auscultation diaphragm, which is attached to the auscultation point. The sound in the body vibrates through the auscultation diaphragm, and then the vibration of the auscultation diaphragm drives the air vibration, and the air vibration is transmitted to the earpiece through the leather tube. That is, the sound is conducted to the doctor's ear through the air. [0003] The first generation of electronic stethoscope did not greatly change the structure of the traditional auscultation head, but placed a microphone inside the auscultation head (or leather tube or tee or earpiece), and the sound vibrated through the diaphragm, using air as the medium to transmit the vibration to the pickup device of the mic...

Problems solved by technology

[0006] The embodiment of the present invention provides a sound pickup method of a stethoscope to solve the technical problems in the prior art that the sound pickup effect is poor, and the traditional auscultation method and the electronic auscultation equipment cannot work at the same time
