Absorbing stethoscope

Abstract

The invention provides an absorption stethoscope, comprising a pickup, a rubber tube, and an earpiece; the output end of the pickup extends a rigid tube, and the rubber tube is orthogonally connected to the side wall of the rigid tube; the end of the rigid tube The part communicates with an absorption cavity, and the absorption cavity is covered with an elastic film that traverses the absorption cavity, and the surface of the elastic film is covered with pinholes. Completely closed; the end of the absorption cavity away from the rigid tube is sealed with an end plate full of through holes; a rod is connected to the center of the elastic membrane, the rod passes through the end plate, and the rod The end is connected with a handpiece. The absorption stethoscope can effectively improve the ability to distinguish pathological features, and is easy for novices to use.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a stethoscope. Background technique [0002] In the medical diagnosis process, a stethoscope is a commonly used medical device, which is mainly used to auscultate the internal signs of the body, such as heart and lung disease problems. Since the human body is a complex system, when listening to the internal sound of the human body, in addition to the specific frequency sound produced by pathological features, it is also accompanied by a large number of common noises. Therefore, if the experience is not rich enough, the characteristic frequency is mixed in the noise. If it is sent into the ear together, it will be difficult for people to distinguish. Therefore, the pathological discrimination ability of ordinary stethoscopes is limited at present. Contents of the invention [0003] In view of the above problems, the object of the present invention is to provide an absorbing steth...
