Abstract

The sound conductor of stethoscope capable of regulating angle includes two symmetrically distributed bows, two ear plugs in the end of the bows and one elastic tab to connect two bows elastically. It features that there are clamping hoops capable of rotating freely around the bow in the joints between the elastic tab and the bow and clamping tab outside the clamping hoop. It has also at least one auxiliary elastic tab, one locking tab and one plastic sheath. The sound conductor of stethoscope can regulate the angle of the bows easily to make the ear plugs plugged in the ears comfortably.

Description

But a kind of stethoscope sound conductor of regulated at will angle

Technical field

But the present invention relates to a kind of ears use, multi-functional, and preferably be furnished with the electronic stethoscope of a camber member.

Background technology

Stethoscope is to be used to detect sound phenomenon or the active instrument of auscultation organ.At present common stethoscope is and to be furnished with the hose type stethoscope of arc sound conductor for the ears use, they all have an open bell or by the parts of membrane sealed as the auscultation head.Except the hose type stethoscope of machinery, also available electronic stethoscope on the market.Stethoscopic auscultation head just is meant a kind of auscultation tube that can be placed on by on the auscultation patient body.The auscultation tube links to each other with a chest piece, and sound conductor leads to earplug from chest piece.

For the hose type stethoscope, acoustical signal through sound conductor, is directly transferred to the doctor's of checking ear from the auscultation tube of auscultation object one side.In traditional sound conductor, the angle of two camber members is regulated at will like a cork, and therefore, what can not be fit to all doctors normally wears use, usually causes that part doctor's ear has more serious sense of discomfort.

Summary of the invention

But the objective of the invention is to provide a kind of stethoscope sound conductor of regulated at will angle for the general doctor, this sound conductor can according to user require the regulated at will angle, make the wearer feel more comfortable.

According to technical scheme provided by the invention, but the stethoscope of regulated at will angle comprises two camber members of symmetric arrangement, the flexure strip that is positioned at the earplug of camber member end and is used for two camber member elasticity are linked together with sound conductor, it is characterized in that: the clamp in that the link setting of flexure strip and camber member can be clipped on the camber member and can freely rotate around camber member is provided for clamping the intermediate plate of clamp in the outside of clamp.

At least 1 auxiliary shell fragment that shape and flexure strip coincide is set on flexure strip, and this auxiliary shell fragment utilizes locking plate to be connected on the flexure strip, and locking plate is clipped on the outside or flexure strip of clamp.Outside at flexure strip and intermediate plate is provided with plastic sheath.

Advantage of the present invention is: because flexure strip adopts clamp being connected with intermediate plate with the connecting portion of camber member, be in a kind of relatively turnable state between clamp and camber member, therefore, user can be according to separately the physiological feature angle of regulated at will camber member voluntarily, makes earplug and ear be in auscultation under the state of the most comfortable; Secondly, owing on the used flexure strip at least 1 auxiliary shell fragment is arranged, therefore, elasticity is more stable, even; In addition, after the connecting portion of flexure strip and camber member is provided with plastic sheath, on the one hand can avoid of the injury of these metalworks, also the elastic force of flexure strip be played cushioning effect on the other hand human body.

The specific embodiment

In following introduction, will describe an embodiment of object of the present invention in detail by accompanying drawing.

But a kind of stethoscope sound conductor of regulated at will angle, comprise two camber members 2 of symmetric arrangement, the flexure strip 7 that is positioned at the earplug 1 of camber member 2 ends and is used for two camber member 2 elasticity are linked together, clamp 3 in that the link setting of flexure strip 7 and camber member 2 can be clipped on the camber member 2 and can freely rotate around camber member 2 is provided for clamping the intermediate plate 4 of clamp 3 in the outside of clamp 3.2 auxiliary shell fragments that shape and flexure strip 7 coincide are set on flexure strip 7, and this auxiliary shell fragment utilizes locking plate 6 to be connected on the flexure strip 7, and locking plate 6 is clipped on the outside or flexure strip 7 of clamp 3.Outside at flexure strip 7 and intermediate plate 4 is provided with plastic sheath 8.

During use, two earplugs 1 on the camber member 2 are placed in the ear, utilize the elastic force of flexure strip 7 to make camber member 2 keep to the inside chucking power, earplug 1 is remained in the ear, can not come off easily, when the doctor feel between earplug 1 and ear because of the angle of camber member 2 not when sense of discomfort is arranged, rotate camber member 2 with hands, make earplug 1 on the camber member 2 just in time be fit to the construction features of ear, at this moment ear will be pleasant.

Because

clamp

3 and 2 of camber members are in a kind of rotating state, the chucking power that clamp 3 and camber member are 2 is provided by intermediate plate 4, therefore, can guarantee the free rotary state of 2 of clamp 3 and camber members, guarantee that again clamp 3 can not rotate or move up and down along camber member 2 arbitrarily under the situation that does not have the external force effect.

Claims

But 1, a kind of stethoscope sound conductor of regulated at will angle, comprise two camber members (2) of symmetric arrangement, the flexure strip (7) that is positioned at the earplug (1) of camber member (2) end and is used for two camber members (2) elasticity is linked together, it is characterized in that: the link setting at flexure strip (7) and camber member (2) can be clipped in the clamp (3) that camber member (2) is gone up and can freely be rotated around camber member (2), is provided for clamping the intermediate plate (4) of clamp (3) in the outside of clamp (3); Outside at flexure strip (7) and intermediate plate (4) is provided with plastic sheath (8).
But 2, the stethoscope sound conductor of regulated at will angle according to claim 1, it is characterized in that: at least 1 auxiliary shell fragment that shape and flexure strip (7) coincide is set on flexure strip (7), should utilize locking plate (6) to be connected on the flexure strip (7) by auxiliary shell fragment, locking plate (6) be clipped on the outside or flexure strip (7) of clamp (3).
3, but as the stethoscope sound conductor of regulated at will angle as described in the claim 2, it is characterized in that: auxiliary shell fragment has two.
