Abstract

The invention relates to medical equipment accessories, especially to accessories of a stethoscope and in particular to a stethoscope listening head. The stethoscope listening head comprises a listening head body and a sound guide passage in the listening head body, wherein the sound guide passage comprises a sound collection surface, a sound guide hole and a lateral sound guide hole, and the sound collection surface, the sound guide hole and the lateral sound guide hole are arranged on the listening head body and are mutually communicated; at least a part of the listening head body is made from a second density material; and the density of the material of the sound guide layer on the sound collection surface is larger than that of the second density material. The stethoscope listening head disclosed by the invention has the advantages of small weight, low cost and no influence on sound listening effect.

Description

technical field

[0001] The invention relates to a medical device accessory, in particular to a stethoscope accessory, in particular to a stethoscope earpiece. Background technique

[0002] Due to the fast conduction speed of sound in high-density materials, small attenuation, and clear hearing, high-density materials such as copper (density 8.9g / cm3), titanium alloy (density 7.82 g / cm3) stainless steel, steel (density 7.8 g / cm3) ), zinc alloy (density 6.58.9g / cm 3 ), etc., solid stethoscope earpieces in the prior art are all made of high-density materials. However, the price of high-density materials is relatively expensive, heavy, and the color is single, and it does not feel light when used.

[0003] Secondly, the commonly used materials for making stethoscope earpieces are titanium alloy, copper, stainless steel, etc. The cost of cutting tools consumed by the stethoscope made of such high-density materials is very high, and the processing time is long and the cost is exp...
