Abstract
The utility model discloses an electronic stethoscope, which comprises a chest piece and an earphone which is movably connected with the chest piece, wherein the chest piece comprises a shell and a sensor which is arranged on the shell, and the sensor is connected with an electronic chip record and play system and a potentiometer. The electronic stethoscope utilizes the sensor to collect the motion sound of internal organs of the human body, and can directly send the sound to the ear of the medical personnel via the earphone, the electronic chip record and play system in the stethoscope applies the electronic chip analog-to-digital conversion technology, the electronic chip digital-to-analogue conversion technology and other technologies, the sound signal is converted into electronic signal and the electronic signal is recorded, then the electrical signal is converted into the sound signal via the digital-to-analogue technology, and users can repeatedly play the record during the diagnose. In addition, because the electronic stethoscope has a compact structure, the earphone and the chest piece are imbedded with each other, so a large quantity of space is saved, and the carrying is facilitated; and the utility model is widely applied, and can be widely applied in the fields of clinical medical treatment, clinical teaching, medical scientific research and the like.
Description
Technical field
This utility model relates to a kind of clinical medical apparatus and instruments of using, particularly a kind of electronic stethoscope.
Background technology
The stethoscope that the doctor uses always be with two earplugs with two flexible rubber tubes be connected to can with the receiver of Body contact on, receiver is the specular cone of a hollow.Stethoscope helps the sound of doctor's auscultation vein, tremulous pulse, the heart, lung, enteral portion, even can hear the hear sounds of fetus in the parent, as a diagnostic tool of early stage thoracic cavity medical science, for huge contribution is made in whole physianthropy development.But traditional stethoscope is because its structural reason; cause lower tone, be subjected to the interferential problem of other noises especially easily; and its velocity of sound, volume can't change; be unfavorable for analyzing more meticulously its sound; and, being unfavorable for the interchange and the consultation of doctors to the state of an illness because the sound of hearing can not repeat to represent, volume is bigger in addition; carry also inconvenience, because the problem of pressure pipe pressure and tin head structure causes drawbacks such as doctor's external auditory meatus discomfort through regular meeting.
The utility model content
The purpose of this utility model is to avoid above-mentioned weak point of the prior art, and a kind of compact volume and convenience be provided, be easy to carry about with one, practical, cost is lower, fidelity is high, can reappear and adjust the electronic stethoscope of the movable sound key element of collecting of human viscera organ.
A kind of electronic stethoscope comprises chest piece and the earphone that flexibly connects with chest piece, and described chest piece comprises housing and be arranged on pick off on the housing that described pick off is connected with electronic chip recording playing system, potentiometer.
Volume and velocity of sound adjusting knob are set on the described potentiometer.
Described earphone is connected with chest piece is embedded.
The silica gel contact is set on the can of described earphone.
Because this utility model stethoscope is collected the movable sound of human viscera organ by means of pick off, can directly sound be imported in medical worker's ear by earphone, electronic chip recording playing system in the stethoscope has been used the electronic chip modulus conversion technique, technology such as digital-to-analogue conversion technology, convert acoustical signal to electronic signal and note, and then process digital-to-analogue conversion technology converts the electrical signal to acoustical signal, user can repeat playing be recorded when making a definite diagnosis, simultaneously can original sound amplification and frequency is slack-off by volume switch on the chest piece and frequency switching, user can clearerly be listened to the sound that obtains.Owing to its compact conformation, the embedded connected mode of earphone and chest piece is saved big quantity space, is easy to carry in addition; The silica gel contact is set on the can of described earphone, the material softness, good airproof performance is difficult for causing between auditory meatus is uncomfortable and significantly minimizing is mixed and disturbs.It is very extensive that this utility model is used, and can be widely used in fields such as clinical, clinic, medical research.
Description of drawings
Below in conjunction with accompanying drawing this utility model is further described:
Fig. 1 is a structural representation of the present utility model;
The specific embodiment
As shown in Figure 1: a kind of electronic stethoscope, comprise chest piece 1 and the earphone that flexibly connects with chest piece 1, described chest piece 1 comprises housing and is arranged on pick off 3 on the housing that described pick off 3 is connected with electronic chip recording playing system 2, potentiometer 4.Stethoscope is collected the movable sound of human viscera organ by means of pick off, can directly sound be imported in medical worker's ear by earphone, electronic chip recording playing system in the stethoscope has been used technology such as electronic chip modulus conversion technique, digital-to-analogue conversion technology, convert acoustical signal to electronic signal and note, and then converting the electrical signal to acoustical signal through the digital-to-analogue conversion technology, user can the repeat playing recording when making a definite diagnosis.The electronics recording and playback ic can be the voice control chip BMP5008 template of Shanghai racing current company brand-new design, this template function is powerful, can playback record simultaneously, with the original sound memory, and can be according to using needs to regulate volume and audio frequency size when repeat playing.
Volume and velocity of sound adjusting knob are set on the described potentiometer 4, can original sound amplification and frequency is slack-off by volume on the chest piece 1 and velocity of sound adjusting knob, user can clearerly be listened to the sound that obtains.For the too small problem that should not listen to of hear sounds volume that some patient's clinically heart change and pulmonary's consolidation etc. cause, volume need be amplified change.Potentiometer changes.Resistance is divided into two controlled gears, and when at first gear, playing sound is former sound, and what play when at second gear is the sound of process frequency transformation.Volume is changed into the knob volume and is changed, and when volume knob was positioned at extreme lower position, volume was patient's actual volume size, can suitably regulate volume by rotary knob.
Described earphone and 1 embedded connection of chest piece are saved big quantity space, are easy to carry.
The silica gel contact is set on the can of described earphone, the material softness, good airproof performance is difficult for causing that auditory meatus is uncomfortable and significantly reduces the noise interference.
