Abstract
A kind of teaching digital stethoscope.Traditional stethoscope cannot capture some faint but very important biological sound that internal organs send, and makes doctor cannot make diagnosis in time, and electronic stethoscope is not enough for this of conventional stethoscope just and develop.A kind of teaching digital stethoscope, its composition comprises: auscultation head (11), described auscultation head is connected with sebific duct (10), described sebific duct is connected with silicon microphone sensor (9), described silicon microphone sensor is connected with digital signal processor (1) by wire (8), and described digital signal processor is circumscribed with display (4) audio amplifier; The logical block that described digital signal processor comprises: onrecurrent mode filter unit, system master unit, fast Fourier transform arithmetic element, frequency spectrum screening its main operational unit, data communication units.This utility model is applied to teaching and uses digital auscultation.
Description
Technical field
this utility model relates to a kind of stethoscope, particularly one teaching digital stethoscope.
Background technology
traditional stethoscope cannot capture some faint but very important biological sound that internal organs send, make doctor cannot make diagnosis in time, electronic stethoscope is not enough for this of conventional stethoscope just and develop, the computer chip of electronic stethoscope configuration, internal organs etc. can be made to send faint biological sound amplify, thus make doctor can not miss any valuable clue, be more easy to judge the contingent pathological changes of the organs such as cardiopulmonary; In the past, on the mixed and disorderly scene of the accident, busy emergency room and noisy ambulance, using traditional stethoscope to come effectively to diagnose, is almost impossible; Along with the generation of electronic stethoscope, this worry of surgeon will become history.
Summary of the invention
the purpose of this utility model is to provide a kind of teaching digital stethoscope.
above-mentioned object is realized by following technical scheme:
a kind of teaching digital stethoscope, its composition comprises: auscultation head, described auscultation head is connected with sebific duct, described sebific duct is connected with silicon microphone sensor, described silicon microphone sensor is connected with digital signal processor by wire, and described digital signal processor is circumscribed with display and audio amplifier; Described digital signal processor comprises logical block: onrecurrent mode filter unit, system master unit, fast Fourier transform arithmetic element, frequency spectrum screening its main operational unit, data communication units.
the beneficial effects of the utility model:
1. the one teaching digital stethoscope of this utility model exploitation, this teaching digital stethoscope can convert the various sound that each for human body organ sends to corresponding level signal, then signal is sent into ASIC process by, analog digital conversion anti-aliasing through operation amplifier, wave filter; Wherein master control ASIC comprises: for the logical block such as onrecurrent mode filter unit, system master unit, fast Fourier transform arithmetic element, frequency spectrum screening its main operational unit, data communication units of different human body organ frequency spectrum, eventually through earphone interface, universal asynchronous receiving-transmitting transmitter or computer USB interface, student can listen to audio frequency via earphone or be shown by connect display.
when adopting general stethoscope, lungs sound very faint (such as friction sound and essence sound), and during with teaching digital stethoscope, then lungs sound is clearly audible; Can clearly identify pleura sound, just be easy to diagnose out extremely early stage pleuritis, not need to remake X-ray with confirmation; General auscultation method can not detect the noise suffering from asthma, and adopt teaching digital stethoscope, academics and students then clearly can tell sound of stridulating, and estimates bronchospasm situation, even can also assess immune homology.
3. in some pathological analysis such as such as gallbladder cystic fibrosis or chronic bronchitis etc., adopt common stethoscope to be can't hear vesicular breathing sound at all, adopt teaching digital stethoscope, teacher just can assess the drippage intensity in vesicular breathing sound, with the patient's condition of monitor patients and therapeutic advance situation.
accompanying drawing illustrates:
accompanying drawing 1 is structural representation of the present utility model, 2-universal asynchronous receiving-transmitting transmitter interface in figure, 3-display interface device, 5-mouse access port, 6-audio amplifier, 7-earphone interface.
accompanying drawing 2 is this utility model Circuits System composition structure charts.
detailed description of the invention:
embodiment 1:
a kind of teaching digital stethoscope, its composition comprises: auscultation head 11, described auscultation head is connected with sebific duct 10, described sebific duct is connected with silicon microphone sensor 9, described silicon microphone sensor is connected with digital signal processor 1 by wire 8, and described digital signal processor is circumscribed with display 4 and earphone 7.
embodiment 2:
teaching digital stethoscope according to embodiment 1, described digital signal processor comprises: the logical blocks such as onrecurrent mode filter unit, system master unit, fast Fourier transform arithmetic element, frequency spectrum screening its main operational unit, data communication units.
embodiment 3:
teaching digital stethoscope according to embodiment 1 or 2, described digital signal processor can convert the various sound that each for human body organ sends to corresponding level signal, then signal is sent into ASIC process by, analog digital conversion anti-aliasing through operation amplifier, wave filter; Eventually through earphone interface, universal asynchronous receiving-transmitting transmitter or computer USB interface, student can listen to audio frequency via earphone or show frequency spectrum to carry out auscultation by connect display.
embodiment 4:
teaching digital stethoscope according to embodiment 1 or 2 or 3, be solidified with the heart of the Healthy People gathered by all ages and classes group, lung, cardiovascular sounds frequency spectrum in described system master unit simultaneously, compare after can the healthy frequency spectrum of the crowd of same age section and the frequency spectrum of patient being inputted by display simultaneously.
embodiment 5:
teaching digital stethoscope according to embodiment 1 or 2 or 3, this stethoscope can use together with sterilizable or disposable barrier film, to check the patient safety ground of immunity degradation or skin extrasensitivity (as burnt degree).
