Problems solved by technology

But the ubiquitous deficiency is exactly that a kind of stethoscope can only auscultate the sound that a kind of viscera sends, and can not auscultate the sound of multiple frequencies that multiple viscera sends, and the equipment structure of existing digital stethoscope is all comparatively complicated, Not for use by physicians alone
In addition, existing electronic stethoscopes are easily affected by external noise, resulting in inaccurate diagnosis

[0033] figure 1 It is a structural diagram of an electronic stethoscope according to the first embodiment of the present invention. Such as figure 1 As shown, the electronic stethoscope includes an auscultation head, a host and a speaker. Among them, the auscultation head is used to contact the body surface during auscultation, so that the acoustic signals radiated from the organs through the body surface resonate, and convert the resonant acoustic signals into electrical signals. The host is used to amplify and filter the electrical signals converted by the auscultation head, and convert the processed electrical signals into acoustic signals. The speaker is used to play the sound signal converted by the host.

[0034] The auscultation head further includes a resonant cavity housing 1, a resonant membrane (in figure 2 Shown in a as 10) and audio collection microphone 2. Among them, the resonant cavity housing 1 is used to resonate the acoustic signal emitted by the organ to ob...

[0085] This embodiment adds the function of digital analysis on the basis of the first embodiment, that is, realizes operations such as the recording of various sounds in the body and the display of sound-related information.

[0086] image 3 It is a structural diagram of an electronic stethoscope according to the second embodiment of the present invention. By comparison image 3 with figure 1 It can be seen that the electronic stethoscope of this embodiment also includes a digital signal circuit 6 and a display screen 7. The digital signal circuit 6 is used to convert the electrical signal filtered by the filter circuit 32 into a digital signal; the display screen 7 is used to display the digital signal. Digital signal converted by circuit 6. Here, a known single-chip microcomputer software that can convert analog signals into digital signals can be used for processing, and then the converted digital signals can be converted into pulse signals that can drive counting after the ...

Abstract

The invention provides an electronic stethoscope. The electronic stethoscope comprises a stethoscope head for being contacted with the body surface during auscultation so that acoustic signals sent by organs and radiated by the body surface generate resonance and the resonance acoustic signals are converted into electric signals, a host machine for amplifying and filtering the electric signals converted by the stethoscope head and converting the electric signals processed into acoustic signals, and a loudspeaker for playing the acoustic signals converted by the host machine. The electronic stethoscope provided by the invention can monitor and record sounds at various frequencies sent by various organs such as heart sounds, bowelsounds, lung sounds, and fetal heart sounds, is suitable for diagnosing various diseases, and is simple in structure and using method, and can effectively isolate external noises so as to improve the diagnosing accuracy.

Description

Technical field [0001] The present invention relates to the technical field of medical devices, in particular to an electronic stethoscope. Background technique [0002] The medical stethoscope uses air as a medium to transmit faint sounds into human ears through a pipe. However, due to some faint but very important biological sounds (such as irregular periodic and random strong bowel sounds) emitted by the internal organs of the human body, it has brought great difficulties to clinical application, which made it impossible for doctors to make timely Diagnosis, and the basis of diagnosis is mainly based on the experience of physicians, and the accuracy is poor. From another perspective, the sensitivity of the human ear to sound is the combined effect of sound intensity and frequency. Therefore, it is difficult to capture some pathological features with a traditional medical stethoscope. Therefore, it is necessary to design an electronic stethoscope that can quantitatively and a...
