Description

A kind of stethoscope

Technical field

This utility model relates to a kind of medical auxiliary apparatus.

Background technology

Stethoscope is a kind of traditional medical auxiliary apparatus, and internist is commonly used to the sound trying to find out in abdominal cavity of patients Sound carrys out assisting in diagnosis and treatment with this.Conventional stethoscope sound is amplified by vibration film, so that what doctor listened Apparent, but owing to the sound amplification of vibration film is limited, to the most small and weak and mixed and disorderly sound The most helpless.

Utility model content

In order to solve problem present in background technology, this utility model provides a kind of stethoscope, this auscultation The relatively conventional stethoscope of device can hear the trickleest and mixed and disorderly sound.

For reaching above-mentioned purpose, this utility model adopts the following technical scheme that

A kind of stethoscope, including visiting line, voice tube and listening sound tube, visits line and listens sound tube to pass through voice tube Being connected, described spy line includes the cylinder-like shell with opening, and the opening part of cylinder-like shell is provided with and shakes Dynamic thin film, cylinder-like shell is internally provided with sound amplifying device, sound amplifying device include sound collector, Sound amplifying circuit and loudspeaker, sound collector is electrically connected with loudspeaker by sound amplifying circuit；

Sound collector is positioned close to vibration film side inwardly, and loudspeaker are positioned close to cylinder-like shell Bottom side, voice tube extend into inside cylinder-like shell from the sidepiece central authorities of cylinder-like shell, sound collection Device and loudspeaker lay respectively at the both sides of voice tube, and voice tube can rotate to relative to cylinder-like shell, loudspeaker towards Vibration film side is arranged, and position relative with loudspeaker on voice conducting pipe is provided with opening.

It is also associated with power supply on described sound amplifying circuit.

The beneficial effects of the utility model are: can use by common stethoscope under normal circumstances, when need Time be capable of hearing trickle mixed and disorderly sound by sound amplifying device.

Accompanying drawing explanation

Detailed description of the invention

This utility model is further described by explanation and detailed description of the invention below in conjunction with the accompanying drawings:

Embodiment 1

As it is shown in figure 1, a kind of stethoscope, including visiting line 30, voice tube 20 and listening sound tube 10, visit sound Portion 30 with listen sound tube 10 to be connected by voice tube 20, visit sound tube 30 by the sound in abdominal cavity of patients by biography Sound pipe 20 is transmitted to fill in the pleasant to the ear sound tube of doctor's ear 10, so that doctor can hear the sound in abdominal cavity of patients Sound.As in figure 2 it is shown, visit the cylinder-like shell 31 that line 30 includes having opening, cylinder-like shell 31 Opening part is provided with vibration film 32, and cylinder-like shell 31 is internally provided with sound amplifying device, and sound amplifies Device includes sound collector 41, sound amplifying circuit 43, loudspeaker 42 and power supply 44, sound collector 41 Electrically connected with loudspeaker 42 by sound amplifying circuit 43, sound amplifying circuit 43 is also associated with power supply 44.

Sound collector 41 is positioned close to vibration film 32 side inwardly, and loudspeaker 42 are positioned close to circle Cylindrical case 31 bottom side, voice tube 20 extend into cylindrical shape from the sidepiece central authorities of cylinder-like shell 31 Shell 31 is internal, and sound collector 41 and loudspeaker 42 lay respectively at the both sides of voice tube 20, and voice tube 20 can Rotate to relative to cylinder-like shell 31.Loudspeaker 42 are arranged towards vibration film 32 side, on voice conducting pipe 20 The position relative with loudspeaker 42 is provided with opening 21.

Under normal circumstances, opening 21 forwarding vibration film 32 side to, sound is after vibration film 32 amplifies Entering voice conducting pipe 20 from opening 21, doctor hears abdominal cavity sound by listening sound tube 10.

When abdominal cavity sound is small cannot very understand time, opening 21 is turned round loudspeaker 42 side, at this time Sound enters through vibration film 32 conduction and visits sound device 30 inside, after sound collector 41 gathers relevant sound Acoustic method circuit 43 broadcasts after amplifying at loudspeaker 42, and the sound that loudspeaker 42 are released is entered by opening 21 Entering voice conducting pipe 20, doctor hears, by listening sound tube 10, the sound that abdominal cavity is small.

Sound collector and sound amplifying circuit described in above-described embodiment are all prior aries, such as tradition The sound-transmitting apparatus that meeting room is installed broadly falls into similar device, is again not described in detail its structure.

This stethoscope can hear the sound that abdominal cavity is the trickleest, contributes to doctor and judges disease more accurately Feelings.

It will be recognized by those skilled in the art, on the premise of without departing from protection scope of the present invention, permissible Above-mentioned embodiment is carried out various amendment, changes and combine, and think this amendment, change and combine Within the scope of originality thought.
