Abstract
The utility model discloses a can gather stethoscope with playback heart sound, including an auscultation section of thick bamboo and earplug, an auscultation section of thick bamboo and earplug pass through the rubber tube and connect, and the one end of an auscultation section of thick bamboo is equipped with the diaphragm, installs permanent magnet, iron core and coil in the auscultation section of thick bamboo, and the coil overlaps on the iron core, and the one end of coil is fixed on the diaphragm, earplug U -shaped support root in the rubber tube has set gradually amplifier circuit, wave filter and chip, amplifier circuit passes through wire and winding connection, still be equipped with the playback switch on the stethoscope, when opening the playback switch, the chip passes through wire and coil switch -on. The utility model discloses can take notes the heart murmur to can pass through the copy mode with the auscultation audio frequency, unloading in cell -phone, computer carry out acoustic wave analysis once more and copy to other stethoscopes, supply other people to carry out the playback auscultation, in order to differentiate the heart disease end of loveization, help improving the success rate of clinical heart auscultation.
Description
Technical field
This utility model relates to a kind of stethoscope, particularly relates to a kind of stethoscope with playback hear sounds that gathers, and belongs to medical instruments field.
Background technology
The blood flow that hear sounds produces when being heart contraction diastole and valve sound, clinicist is by stethoscope, and the normal noise of Diagnosing Cardiac and pathologic murmur, carry out heart disease diagnosis.Due to the change of patient body position, cardiac function, as deterioration, rehabilitation, the situation such as effective, cardiac auscultation result all can be made to change, therefore need the hear sounds each time of store patient, contrast to facilitate.Other has the noise of very strong personal feature and clinic meaning, also needs to preserve, and repeats research patient's hear sounds and teaching use to facilitate doctor.Especially to Special cases, need many people simultaneously auscultation, what adopt at present is auscultation in turn, and this must cause, and patient's is discontented, therefore provides a kind of and can preserve auscultation cardiac murmur and the stethoscope recording playback just seems very important.
Summary of the invention
The purpose of this utility model is that providing a kind of preserves and the stethoscope of playback cardiac murmur.
What this utility model provided gathers the stethoscope with playback hear sounds, and comprise stethoscope and earplug, stethoscope is connected by sebific duct with earplug, one end of stethoscope is provided with barrier film, be provided with permanent magnet, iron core and coil in stethoscope, coil is enclosed within iron core, and one end of coil is fixed on barrier film; In sebific duct, be positioned at earplug U-shaped support root area be disposed with amplifying circuit, wave filter and chip, described amplifying circuit is connected with coil by wire; Stethoscope is also provided with playback switch, and when opening playback switch, chip is connected by wire and coil.
Stethoscope is also provided with bluetooth and signal transmission port.
This utility model can record cardiac murmur, and auscultation audio frequency can be passed through copy mode, unloading is in mobile phone, computer, carry out acoustic wave analysis again and be copied to other stethoscopes, carrying out playback auscultation for other people, thus can at different time points, check hear sounds, carry out front and back to compare, to differentiate heart change of illness state, contribute to the success rate improving clinical heart auscultation.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model (sebific duct not shown in FIG. and earplug).
In figure: 1-chip, 2-wave filter, 3-amplifying circuit, 4-stethoscope, 5-annular permanent magnet, 6-iron core, 7-coil, 8-wire, 9-barrier film
Detailed description of the invention
As shown in Figure 1, this utility model comprises stethoscope 4 and earplug, and stethoscope 4 is connected by sebific duct with earplug, and the lower end of stethoscope 4 is closed with barrier film 9, and upper end is provided with annular permanent magnet 5 and iron core 6, and coil 7 is enclosed within iron core 6, and lower end is pasted on barrier film 9.In sebific duct, be positioned at earplug U-shaped support root area be disposed with amplifying circuit 3, wave filter 2 and chip 6, when stethoscope has vibrations, coil 7 cutting magnetic line and produce micro-electric current (i.e. the acoustic signals of cardiac murmur), this micro-electric current enters amplifying circuit 3 by wire 8 by coil 7 and amplifies, then enter wave filter 2 significantly single interfering noise is filtered, finally by wire transmission on chip 1, after carrying out biometrics storage, transfer to computer or mobile phone by bluetooth transmitting terminal.
This utility model is also provided with playback switch, when opening playback switch, chip 1 by digital signal by wire transmission to coil 7, coil 7 starts concussion, drive barrier film 9 to produce vibrations, sound wave transfers to ear plug of stethoscope by sebific duct, and user can hear the playback of hear sounds.
The above is only a kind of embodiment of the present utility model, but protection domain of the present utility model is not limited thereto, any based on scheme of the present utility model with conceive the improvement carried out and replace and all should be encompassed in protection domain of the present utility model.
