Problems solved by technology

[0004] In the process of manual assembly of stethoscopes, the hearing effect of the assembled stethoscopes is different due to different people. Even the same person cannot guarantee the same assembly. Therefore, how to make the diaphragm work in the best working condition has always been a problem in the industry.

Abstract

Disclosed is a matching structural assembly of a stethoscope head body (1) and a fixed part (2), the assembly comprising the stethoscope head body (1) and the fixed part (2). A revolving shaft hole (11), a sound leading hole (12) and a sound collecting face (13) which connect with one another are arranged on the stethoscope head body (1). A through hole (21) and a semi-through hole (22) with coincident axes and different bore diameters are arranged on the fixed part (2) along the axis. An annular step (14) is arranged on the stethoscope head body (1) at one side of the sound collecting face (13) and at least comprises a first annular side (141), a first bottom (142) and a second annular side (143), the first side (141) is connected with the second side (143) through the first bottom (142), and the fixed part (2) is fixed with the annular step (14) in a matching way. The present invention has the advantages that the products are good in consistence, and the hearing effect is perfect.

Description

technical field [0001] The invention relates to a medical device accessory, in particular to a stethoscope accessory, specifically a matching structural assembly of a stethoscope earpiece body and a fixing piece and a method for adjusting a diaphragm in the stethoscope to a predetermined tension using the structure. Background technique [0002] A stethoscope is assembled from multiple parts, mainly including a diaphragm, a listening head body, a fixing piece, a rotating shaft, a rubber tube and an earhook. When in use, the diaphragm is fixed on the listening head body through the fixing piece, and the diaphragm and the listening head body form a sound collecting cavity, and the sound of the organs is amplified in the sound collecting cavity through the diaphragm, and is connected to the listening head body The rotating shaft is transmitted to the rubber tube, and then transmitted to the earhook through the rubber tube for the user to listen to. Thus the diaphragm plays a v...
