Description

A kind of stethoscope

Technical field

The utility model belongs to medical instruments field, specifically a kind of stethoscope.

Background technology

Stethoscope is the most frequently used diagnosis apparatus of inside and outside woman doctor, is the mark of doctor, and modern medicine is to start from auscultation The invention of device, mainly listens heart and respiratory system, and conventional stethoscope soundproof effect is poor, readily hears external noise.

Utility model content

The utility model, which provides a kind of stethoscope, can reduce the influence of external noise.

The technical solution of the utility model is as follows：A kind of stethoscope, including earplug, listening tube and the being sequentially connected；Institute Stating can includes listening head body and eardrum, and the inner chamber of the eardrum and the listening head body is formed on membrane cavity, the listening head body Provided with the film cover corresponding with the eardrum, spring is connected between the film cover and the eardrum.

Further, the coefficient of elasticity of the spring is according to heartbeat, gurgling sound, bubble etc. the even audio of blood flow Depending on.

Further, blimp is also fixedly connected between the listening tube and the can, the blimp can cover described Can.

Further, a kind of stethoscope also includes sound panel, and the sound panel is made up of two vertical annulus, it is described every A wherein annulus for soundboard is located between the blimp and the can, an other annulus and the sound insulation of the sound panel Plate is connected by sponge.

Further, the earplug is flexibly connected with the end of the listening tube, and the end of the earplug can be with the listening tube End is rotated against.

Further, the end of the earplug has groove, and the end of the listening tube has projection, and the projection can be stuck in institute State in groove and can be rotated in the groove.

Further, the end of the earplug is connected with follow block by spring, and the follow block can be pushed against in the projection.

Further, the listening tube has cavity.

Beneficial effect：The earplug of the present utility model, listening tube and can are combined into stethoscopic basic framework, internal sound Ripple is agitated to drive the membrane cavity closed gas to shake therewith by the eardrum, then sound is passed to by the listening tube The earplug, is listened to when using by the earplug, and other can be reduced by being connected with spring between the film cover and the eardrum Influence of the sound wave to the eardrum, so as to reduce the influence of external noise.

Embodiment

The utility model is described in further detail below in conjunction with the accompanying drawings.

As shown in Figure 1, Figure 2 and as shown in figure 3, a kind of stethoscope of the utility model, including earplug 1, the and of listening tube 2 being sequentially connected Can 3；The can 3 includes listening head body and eardrum 31, and the inner chamber of the eardrum 31 and the listening head body forms membrane cavity 33, The listening head body is provided with the film cover 32 corresponding with the eardrum 31, is connected between the film cover 32 and the eardrum 31 Spring 4.

The earplug of the present utility model, listening tube and can are combined into stethoscopic basic framework, and sound in the body passes through institute State eardrum to agitate so as to driving the membrane cavity closed gas to shake therewith, then sound passed to the ear by the listening tube Plug, listens to by the earplug when using, is adjacent to human body skin by the film cover, it is to avoid the eardrum directly contacts skin, Influence of other sound waves to the eardrum can be reduced by being connected with spring between the film cover and the eardrum, particularly compare human body The smaller sound wave of intensity of acoustic wave, when eardrum described in such sonic impinging, due to the pulling force effect of spring, the eardrum is agitated very It is small, so as to reduce such sound that the earplug is heard, user is not more heard human heartbeat's sound, gurgling sound, bubble Deng so as to reduce the influence of external noise.

As specific embodiment, the coefficient of elasticity of the spring 4 is according to the even blood such as heartbeat, gurgling sound, bubble Depending on the audio of flowing, particularly heartbeat is at 20 decibels or so, so the elasticity of the spring 4 can be according to less than 12 decibels To formulate.

As specific embodiment, blimp 5, the blimp are also fixedly connected between the listening tube 2 and the can 3 5 can cover the can 3, and the can 3 can be reduced interference of the external environment to the can 3 by the blimp 5.

As specific embodiment, in order to preferably reduce interference of the external environment to the can 3, a kind of auscultation Device also includes sound panel 6, and the sound panel 6 is made up of two vertical annulus, and a wherein annulus for the sound panel 6 is positioned at described Between blimp 5 and the can 3, an other annulus for the sound panel 6 is connected with the sound panel 6 by sponge 7, when logical When crossing 3 tins of body sounds of can, human body skin extrudes the sound panel 6, the sound panel 6 is connected the sponge 7 Annulus is slowly contacted to the blimp 5 close to until human body skin with the film cover 32.

It is used as specific embodiment, it is contemplated that when people hangs the earplug 1 on ear, the earplug 1 may be made in ear Interior twisting, the earplug 1 is flexibly connected with the end of the listening tube 2, the end that the end of the earplug 1 can be with the listening tube 2 Rotating against so described earplug 1 would not rotate to sprain ear inside ear.

As specific embodiment, the end of the earplug 1 has groove 11, and the end of the listening tube 2 has projection 22, Described raised 22 can be stuck in the groove 11 and can be transferred in the inward turning of groove 11 and realize the earplug 1 and the listening tube 2 End rotation.

As specific embodiment, the end of the earplug 1 is connected with follow block 8 by spring 9, and the follow block 8 can be pushed against External sound is avoided to have influence on the junction of the listening tube 2 and the syrinx 2 on described raised 22.

As specific embodiment, the listening tube 2 has cavity 21, and the cavity 21 should be narrow enough so as to amplify patient's body Interior acoustic wave vibrations.

Embodiment of the present utility model is these are only, the scope of the claims of the present utility model, every profit is not thereby limited The equivalent structure made with the utility model specification and accompanying drawing content, is directly or indirectly used in other related technology necks Domain, similarly within scope of patent protection of the present utility model.
