Abstract
The utility model discloses a stethoscope reducing stethoscope effects and belongs to the technical field of the angiocarpy clinical speciality. The stethoscope reducing the stethoscope effects is characterized by comprising an ear piece, an audio cable and a stethoscope head, wherein the ear piece, the audio cable and the stethoscope head are sequentially connected. The ventral side of the stethoscope head is a film type audio collector which is connected with an analog-digital converter. A digital signal of the analog-digital converter is transmitted to the ear piece through the audio cable. The ear piece is in a Y shape, and the two top ends of the ear piece are loudspeakers. The lower end of the ear piece is the audio cable. Compared with the prior art, the stethoscope reducing the stethoscope effects has the advantages of being simple in structure and high in stethoscopy accuracy.
Description
Technical field
This utility model relates to a kind of stethoscope, particularly a kind of stethoscope that reduces stethoscope effect.
Background technology
At present, stethoscope is of a great variety, and the stethoscope of different brackets difference when listening normal sound equipment is also not too obvious, but is just as far apart as heaven and earth while listening cardiac murmur.In general, stethoscopic quality is higher, and stronger to the discrimination ability of noise, the time of use is also longer.A clinicist should the better stethoscope of an at least standing substandard goods matter.In general, stethoscope is heavier more greatly, and pickup effect is better, contrary, more little lighter, carry Vietnamese side just, the design of giddy stethoscope is exactly in order to solve this contradiction, and therefore a kind of pickup effect stethoscope good, that noise is few, easy to carry is necessary.
Stethoscopic conduction portion, acoustic pipeline is also very heavy, and the internal diameter of pipeline is larger, length is shorter, tube wall is thicker, and stethoscopic effect is better, and international standard length is 27 inches.When checking, generally need hand-held auscultation head, auscultation head is placed on to check point, vibrations and friction that finger or other interference cause, increased interference factor, reduces the preparatory of auscultation.
Existing stethoscope is not made very large improvement for stethoscope effect, thereby has affected the effect of auscultation, to a certain degree affected auscultation in the better development aspect medical science.
Utility model content
Technical assignment of the present utility model is for above the deficiencies in the prior art, and a kind of stethoscope that reduces stethoscope effect is provided.
The technical scheme in the invention for solving the technical problem is: a kind of stethoscope that reduces stethoscope effect, it is characterized in that: comprise the ear piece, tone frequency channel wire and the stethoscope head that are linked in sequence, the described stethoscope head outside of belly is membrane type audio collection device, described membrane type audio collection device is connected with analog-digital converter, and described analog-digital converter digital signal is transferred to ear piece by tone frequency channel wire; Described ear piece is Y shape, and two tops of ear piece are speaker, and ear piece lower end connects tone frequency channel wire.
Above-mentioned speaker is electrostatic loudspeaker.
Above-mentioned ear piece lower end be linked in sequence transformator, power amplifier and tone frequency channel wire.
The above-mentioned stethoscope head back side is also provided with convex stripe.
Compared with prior art, the utlity model has following outstanding beneficial effect.
1, lead the stethoscope head outside of belly and be membrane type audio collection device, simple in structure, two tops of ear piece are electrostatic loudspeaker, have response speed fast, the various small details of can resetting, the feature that distortion is extremely low.
2, the stethoscope head back side is provided with convex stripe, and friction and vibrations that stricture of vagina can reduce hands produce noise, the accuracy while having improved auscultation.
3, in this utility model, all electronic components are prior art, all can from market, buy, and assembly cost is low.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with specification drawings and specific embodiments, this utility model is further illustrated.
As shown in Figure 1, this utility model comprises ear piece 1, tone frequency channel wire 3 and the stethoscope head 2 being linked in sequence.
Described stethoscope head 2 outside of belly are membrane type audio collection device, membrane type audio collection device can be collected the sound of check point, described membrane type audio collection device is connected with analog-digital converter, and analog-digital converter can become digital signal by audio signal, and digital signal is transferred to ear piece 1 by tone frequency channel wire 3.Ear piece 1 is Y shape, and ear piece 1 lower end connects tone frequency channel wire 3, and two tops of ear piece 1 are speaker 5, can for coil-moving speaker, etc. magnetic loudspeaker, in prioritization scheme, be electrostatic loudspeaker.Electrostatic loudspeaker is prior art, and its structure is that vibrating diaphragm is suspended in the electrostatic field being formed by two fixing metallic plates (stator), and when audio signal is loaded on stator, electrostatic field changes, and drives vibrating diaphragm vibration.Be characterized in: response speed is fast, the various small details of can resetting, distortion is extremely low.But this kind of electrostatic loudspeaker is not easy to drive, so need to install additional transformator 6 and power amplifier 7 between ear piece 1 lower end and tone frequency channel wire 3, be i.e. linked in sequence transformator 6, power amplifier 7 and tone frequency channel wire 3 of ear piece 1 lower end.
Described stethoscope head 2 back sides are also provided with convex stripe 4, and friction and vibrations that striped can reduce hands produce noise, the accuracy in the time of can effectively improving auscultation.
In this utility model, all electronic components are prior art, and its concrete structure is not repeated.
It should be noted that; particular of the present utility model have been described in detail this utility model; for a person skilled in the art, the various apparent change of in the situation that not deviating from spirit and scope of the present utility model, it being carried out is all within protection domain of the present utility model.
Claims (4)
