Abstract

The present invention provides a kind of accurate stethoscope, including sound pick-up, has the pickup chamber of a closing inside the sound pick-up, and the front of pickup chamber is covered by elastic thin layer, forms the pickup face of sound pick-up；The back side of the sound pick-up has pedestal, a slideway with pickup chamber coaxial communication is formed in the pedestal, matching has sliding plug block in the slideway, the afterbody of the sliding plug block exposes the pedestal, pass through the pressing of finger, sliding plug block can be made to be moved axially in the slideway, to adjust the pressure of the pickup intracavitary；The pickup intracavitary is additionally provided with a mini microphone, and the mini microphone is exported to audio processing modules, and the audio processing modules are exported to a set of headphones.The accurate stethoscope can be directed to different human body auscultation positions, the shape in pickup face adaptively be adjusted, so that pickup face is nearly bonded human body auscultation position, to obtain excellent pickup effect.

Description

Accurate stethoscope

Technical field

The present invention relates to medical instruments field, especially, is related to a kind of stethoscope.

Background technology

Stethoscope is a kind of conventional medicine equipment, is mainly used in listening in clinical diagnostic process dirty inside patient body The distinctive tone of device, to judge the state of an illness.In use, the pickup face of sound pick-up is bonded better stethoscope with patient body, Then pickup effect is better；But stethoscopic pickup face shape is substantially stationary at present, and the human body of required auscultation is special Sign is change, such as be directed to different human bodies, or the human body of different building shape, and the shape and elasticity on auscultation surface are all respectively not It is identical, this pickup face fixed for shape, it is difficult to keep good pickup effect for a variety of situations.

The content of the invention

In view of the above-mentioned problems, it is an object of the invention to provide a kind of accurate stethoscope, the accurate stethoscope can be directed to Different human body auscultation positions, the shape in pickup face is adaptively adjusted, so that pickup face is nearly bonded human body auscultation position, To obtain excellent pickup effect.

The technical solution adopted for the present invention to solve the technical problems is：The accurate stethoscope includes sound pick-up, described to pick up There is the pickup chamber of a closing, and the front of pickup chamber is covered by elastic thin layer, forms the pickup face of sound pick-up inside sound device； The back side of the sound pick-up has pedestal, and a slideway with pickup chamber coaxial communication, interior of the slideway are formed in the pedestal Equipped with sliding plug block, the afterbody of the sliding plug block exposes the pedestal, by the pressing of finger, can make sliding plug block in the slideway interior axle To movement, to adjust the pressure of the pickup intracavitary；The pickup intracavitary is additionally provided with a mini microphone, the miniature Mike Wind is exported to audio processing modules, and the audio processing modules are exported to a set of headphones.

Preferably, the pickup face is made up of rubber membrane or resin sheet.

Preferably, the inner of the sliding plug block is popped one's head in provided with air pressure, the outer end of sliding plug block is provided with air pressure gauge outfit；The gas It is in nahlock shape to press gauge outfit, coaxial with the sliding plug block.

Preferably, also include recording module in the audio processing modules, so that mini microphone pickup Physiological characteristic sound can be replayed.

The beneficial effects of the present invention are：In use, the pickup face of sound pick-up is covered in for the accurate stethoscope Behind human body auscultation position, the sliding plug block can be pressed with finger, increases the air pressure of pickup intracavitary, so that the pickup face is encircleed To auscultation position, make being bonded closely everywhere for pickup face and auscultation position, so as to obtain excellent auscultation effect.

Brief description of the drawings

Fig. 1 is the schematic diagram of this accurate stethoscope one embodiment.

Fig. 2 is the schematic top plan view of sound pick-up in Fig. 1 embodiments.

Embodiment

The present invention is further described with reference to the accompanying drawings and examples：

In the embodiment shown in Fig. 1, Fig. 2, the accurate stethoscope includes sound pick-up 1, has an envelope inside the sound pick-up The pickup chamber 10 closed, and the front of pickup chamber 10 is covered by elastic thin layer, forms the pickup face 11 of sound pick-up；The sound pick-up 1 The back side there is pedestal 12, a slideway 120 with the coaxial communication of pickup chamber 10 is formed in the pedestal 12, in the slideway 120 Matching has sliding plug block 13, and the afterbody of the sliding plug block 13 exposes the pedestal 12, by the pressing of finger, sliding plug block 13 can be made to exist Moved axially in the slideway 120, to adjust the pressure in the pickup chamber 10；A miniature wheat is additionally provided with the pickup chamber 10 Gram wind 2, the mini microphone 2 are exported to audio processing modules（It is not shown, it can be located in pedestal 12）, the audio frequency process mould Block is exported to a set of headphones 3.

Above-mentioned accurate stethoscope, the pickup face 11 are made up of rubber membrane or resin sheet.The inner of the sliding plug block 13 Popped one's head in provided with air pressure, the outer end of sliding plug block 13 is provided with air pressure gauge outfit 14；The air pressure gauge outfit 14 is in nahlock shape, with the sliding plug block 13 is coaxial；So as to while sliding plug block 13 is pressed, it is possible to the pressure values of air pressure gauge outfit 14 are seen, so that in pickup chamber 10 Pressure is accurate to reasonable level, makes to keep rational contact between pickup face 11 and human body auscultation position.

Furthermore it is also possible to the audio processing modules are made to include recording module, so that the life that the mini microphone 2 picks up Reason distinctive tone can be replayed, to study written in water pathological characters sound repeatedly.

Above-mentioned accurate stethoscope in use, can after the pickup face 11 of sound pick-up 1 is covered in into human body auscultation position The sliding plug block 13 is pressed with finger, increases the air pressure in pickup chamber 10, so that the pickup face 11 is encircleed to auscultation position, Make being bonded closely everywhere for pickup face 11 and auscultation position, so as to obtain excellent auscultation effect.

The foregoing is only presently preferred embodiments of the present invention, be not intended to limit the invention, it is all the present invention spirit and Within principle, any modification for being made, equivalent substitution, it should be included in the scope of the protection.
