Abstract

The utility model belongs to a medical appliance which is a stethoscope composed of earplugs, an auscultation rod, a bow-shaped spring sheet, a rubber pipe, a three-way pipe, and a stethoscope head. The utility model is characterized in that the upper side of each of two earplugs is respectively fixed with a nest-shaped elasticity cover which can not clog the mouth of each of the earplugs; the utility model can cover the ear holes and effectively block off the external noise; the sound introduced into the ears through the stethoscope is clearer, and the mouths of the earplugs can not be directly clamped in the ear holes because of proper elasticity to make the ears more comfortable; in addition, the bow-shaped spring sheet can form an upwards bent shape, when used, the utility model is worn on the head to prevent the phenomenon that the nest-shaped elasticity cover moves downwards from appearing.

Description

Stethoscope

This utility model belongs to a kind of medical apparatus and instruments.

When auscultation, in order to make the sound that imports in the ear by stethoscope more clear, also for stethoscopic earplug is not fallen down from ear, existing stethoscopic earplug is all thinner, can tightly snap under the effect of arcuate bombing leaf in the earhole, because people's earhole position nerve is relatively more flourishing, and earplug is harder, so many doctors earhole are in use blocked very uncomfortablely, particularly when arcuate bombing leaf elastic force is big, the skin around the earhole sometimes even can be galled; In addition, though earplug can tightly snap in the earhole, but still earhole can not be blocked fully, extraneous noise also can partly import into, influences the auscultation effect.

The purpose of this utility model, it is more clear just to provide a kind of sound that imports in the ear by stethoscope that makes, and don't earplug is tightly snapped in the earhole, makes the more comfortable stethoscope of ear.

A kind of stethoscope of forming by earplug 1, auscultation bar 2, arcuate bombing leaf 3, sebific duct 4, tee T 5, auscultation 6 etc., it is characterized in that respectively being fixed with a nest-shaped elastic shield of not blocking the earplug mouth on said two earplugs, it can cover earhole, block outside noise effectively, the flexible again earplug mouth that makes can directly not snap in the earhole; In addition, described arcuate bombing leaf can be the shape and the sebific duct that are bent upwards and lay respectively at earplug both sides up and down, can be worn on the head during use.

Description of drawings: Fig. 1 is embodiment 1 sketch map, wherein, and 1-earplug, 2-auscultation bar, 3-arcuate bombing leaf, 4-sebific duct, 5-tee T, 6-auscultation head, 7-nest-shaped elastic shield.

Embodiment 1: with conventional method with auscultation bar, arcuate bombing leaf, tee T, auscultation is first-class installs, each fixes a nest-shaped elastic shield that be able to fasten ear that makes with rubber on two earplugs then, the earplug mouth is opened on the inwall of nest-shaped elastic shield.In use, as long as two nest-shaped elastic shields are buckled in respectively on two on the ear, can use according to a conventional method; Under the effect of arcuate bombing leaf, nest-shaped elastic shield can cover earhole more closely, block outside noise effectively, the sound that passes to the earplug mouth from the auscultation head can more clearly be imported into the ear, again because rubber itself has certain elasticity, earplug can directly not snap in the earhole, and therefore, originally the sort of because earplug snaps in the uncomfortable sense that earhole brings and just disappeared naturally.

Embodiment 2: the arcuate bombing leaf among the embodiment 1 is changed into by original being bent downwardly be bent upwards and sebific duct etc. is positioned at the earplug both sides respectively, size is advisable on the head being worn over; During use arcuate bombing leaf is worn on the head, nest-shaped elastic shield is buckled in respectively on two ears and can uses according to a conventional method; This structure except advantage with embodiment 1, can also prevent stethoscope service time long after, arc bouncing plate elastic force dies down and phenomenon that the nest-shaped elastic shield that occurs moves down.

The utility model is compared with existing stethoscope, is not that thin and hard earplug is direct Snap in the earhole, ear can be more comfortable during use; Not a part that only clogs earhole, But more whole earhole is covered from the outside, so the more difficult ear that imports into of ambient noise In, make auscultation more clear, judge more accurate.

Claims

1, a kind of by earplug 1, auscultation bar 2, arcuate bombing leaf 3, sebific duct 4, tee T 5, auscultation 6 stethoscope of forming, it is characterized in that respectively being fixed with a nest-shaped elastic shield of not blocking the earplug mouth on said two earplugs, it can cover earhole, block outside noise effectively, the flexible again earplug mouth that makes can directly not snap in the earhole.

2, stethoscope according to claim 1 is characterized in that described arcuate bombing leaf can be the shape that is bent upwards and sebific duct etc. and be positioned at both sides about the earplug respectively, can be worn on the head during use.
