Problems solved by technology

The structure of the stethoscope pickup head is mainly divided into a membrane surface and a clock surface. In addition, the common double-headed stethoscopes on the market mostly use riveting technology to assemble the listening rod components. The processing requirements for the size of the assembly hole of the listening head body are relatively high, and it is easy to loosen and fall off.
Especially when the earpiece body is made of difficult-to-machine materials, such as stainless steel, titanium alloy, etc., the processing cost is high and the yield is low
Those skilled in the art want to try to design a kind of stethoscope that can replace listening head at any time always, but design scheme is not ideal always

Description

technical field [0001] The invention relates to a stethoscope, in particular to a stethoscope chest piece with a replaceable sound pickup area, which belongs to the technical field of medical equipment. Background technique [0002] The stethoscope is the most commonly used diagnostic tool for internal and external gynecologists and pediatricians. Since the stethoscope was used clinically, its shape and sound transmission method have been continuously improved, but its basic structure has not changed much. The sound guide tube and the listening part are earpieces. [0003] Because most of the common double-head stethoscopes on the market adopt a fixed double-head non-replaceable design, users need to replace stethoscopes of different models when using them for different groups of people, which increases the user's cost of use. The people used by stethoscopes are roughly divided into newborns, children, and adults. When auscultating different groups of people and body parts,...
