Description

a stethoscope

technical field

The invention relates to the field of medical supplies, in particular to a stethoscope.

Background technique

The stethoscope is the most commonly used diagnostic tool for internal and external gynecologists and children, and is a symbol of doctors. Modern medicine began with the invention of the stethoscope. Since the stethoscope was used clinically, its shape and sound transmission method have been continuously improved, but its basic structure has not changed much. It is mainly composed of the sound pickup part, the conduction part and the listening part. Stethoscopes currently on the market are used in winter When the patient touches the stethoscope head, the stethoscope head is relatively cold, and every patient uses the stethoscope head, which is unhygienic and prone to cross-infection. The invention patent application number is CN: 201010272297.9, which discloses a stethoscope. The stethoscope is made of It is composed of chest piece, listening tube, ear tube and earplugs. There is a buckle cover on the chest piece, and an electronic stopwatch is set on the buckle cover. This solution effectively improves the accuracy of auscultation by doctors. Cross-infection between patients, more importantly, can not give patients a comfortable feeling, which is not conducive to popularization and application.

Contents of the invention

The object of the present invention is to provide a stethoscope to solve the above-mentioned deficiencies caused in the prior art.

The technical scheme adopted by the present invention is:

A stethoscope, comprising earplugs and listening tubes, the middle part of the listening tube is provided with a branching part, the bottom of the listening tube is provided with a listening cover, the branching part is provided with a nylon buckle, and the inside of the listening tube between the earplugs and the nylon buckle is provided with sound insulation Sleeve, the length of the listening tube is 1.0-1.5m, there is a heater on the listening tube close to the listening cap, a switch is set on the heater, a shielding layer is provided at the earplug, the listening cap is a sandwich structure, and the outer surface of the listening cap is set There are switches.
