Problems solved by technology

However, this kind of stethoscope with exclusive use for specific organs has a limited range of application, so that it is often necessary to reserve multiple stethoscopes for different functions (i.e. organs), so that different stethoscopes need to be replaced when the organs to be measured are different, which not only causes doctors to auscultate Inconvenience, and the high cost of the instrument due to the quantity relationship, even if the same pair of stethoscopes are used to replace the auscultation head, it will cause inconvenience due to the replacement of the auscultation head, and because the original price of the auscultation head is not low. The bandwidth required by the stethoscope designed for a specific organ is more accurate, resulting in a high cost of the stethoscope

Embodiment Construction

[0016] In view of the inconvenient operation and high cost caused by the replacement of different stethoscopes or stethoscope heads in previous stethoscopes, the present invention directly separates and processes the signals inside the stethoscope, that is, the stethoscope head obtains the signal before using the active frequency band of the corresponding organ. The corresponding band-pass filter is used to extract the required sound, which is different from the previous use of different auscultation heads to only extract the signal of the corresponding organ frequency band and feed it into the processing, so as to solve the previous shortcomings. The main technical means of the present invention is to use multiple band-pass filters inside the stethoscope, and each band-pass filter corresponds to the active sound range of different organs in the human body, so as to capture the corresponding organ active sounds, so as to achieve a more realistic presentation of the organs to be ...

Abstract

The invention is a multifunctional electronic stethoscope, including a sensor, a band-pass filter set, a D / A converter, a micro-controller and a speaker. Its character: the filter set contains multiple band-pass filters corresponding to different sound bands, the stethoscope also has an input unit for the user to input mode-switch command, and the micro-controller receives the command to select one signal of band-pass filter corresponding to the command and then outputs the signal to the speaker.

Description

(1) Technical field [0001] The invention relates to an electronic stethoscope, in particular to a multifunctional electronic stethoscope which can selectively listen to heart sounds, lung sounds and bowel sounds. (2) Background technology [0002] Auscultation is a very widely used method in clinical practice. For example, listening to heart sounds can diagnose arrhythmia and heart valve disease, listening to lung breathing sounds can diagnose most lung diseases, and listening to bowel sounds includes the sound of gastric activity and intestinal peristalsis. These are clinically important reference materials, making the stethoscope a representative symbol of doctors. [0003] Stethoscope is mainly used to listen to the lungs of human body, heart and abdominal activity situation at present. Such as figure 1 Shown is a conventional electronic stethoscope 1, which has a fork tube 11, a stethoscope head 12, a receiver 14 and two earplugs 13. The fork pipe 11 has a main pipe 1...
