The cow simulation model stethoscope is composed of a cow simulation model and a stethoscope, wherein, a control box of the stethoscope comprises a microprocessor, a speech chip, a display and a power amplifier. The utility model is characterized in that the cow simulation model is provided with an auscultation point which can control the speech chip by a control panel; sound signals can be sent to the corresponding auscultation point after magnified by selecting a needed speech segment; generated sounds of the corresponding position of the cow simulation model can be heard only by pointing the auscultation point, and people can hear simulation heart sounds and breath sounds of different heart-lung diseases; thereby, various states of a cow can be known. The utility model is simple, visual, lifelike and intuitional, and can be used as the teaching appliance for diagnosing cow heart-lung diseases.

Description

Ox emulation auscultation instrument

Technical field

The utility model relates to a kind of simulation teching instrument, especially relate to a kind of can mock bull decentraction lung disease hear sounds and the emulation auscultation instrument of breath sound.

Background technology

At present, known this type of analogue means partly is made up of single-chip microcomputer (8031), scratch pad memory (EPROM), digital to analog converter (DAC), binary counter etc., and " scratch pad memory (EPROM) is as the chip of stored sound; Voice signal is stored in the scratch pad memory (EPROM) by analog to digital conversion after sampling, and tonequality is relatively poor, and it is bigger to take the storage area, the hear sounds of storage, and breath sound sound kind is less; Afterwards, Chinese patent CN 97243475.5 provided the automatic cardiopulmonary of a kind of perfect in shape and function, auxiliary auscultation teaching to listen and touched analog meter, and it can simulate tens kinds of hearts, lung, thoracic cavity, abdominal cavity noise.Both can be by outer relieved sound of loudspeaker or breath sound, modal patient's that can be true to nature situation allows the student carry out the auscultation exercise with various ill hear sounds or the corresponding physiological location of breath sound again; In teacher gave lessons process, it can put the type feature explanation of required ill hear sounds or breath sound and speech form by built-in loudspeaker outward, was shown the frequency of this hear sounds or breath sound simultaneously by frequency indication charactron; When the student carries out the auscultation exercise, can play out the voice suggestion of hear sounds or breath sound type feature by outgoing loudspeaker, hear sounds or breath sound are then not outer to be put, the student can be with stethoscope under the indication of display, hear in patient's corresponding physiological location on one's body, the pronunciation of physiological location and different disease associations are controlled according to the best audition position of various disease correspondence automatically by microprocessor; In the examination process, then maskable falls voice suggestion and physiological location prompting, goes analysis and judgement by student oneself.But, existing the diagnosis of Animal diseases is required great effort and inconvenience is carried out on the classroom very much, also lifelike image not.

Summary of the invention

In order to overcome the problem of the not true to nature and inconvenience of existing animal diseases diagnosis, it is the purpose of this utility model that a kind of ox emulation auscultation instrument of lifelike image is provided.

Technical solution adopted in the utility model is: the control box of auscultation instrument comprises microprocessor (CPU1) and microprocessor (CPU2), microprocessor (CPU1) links with microprocessor (CPU2), microprocessor (CPU1) links with speech chip (A1) and speech chip (A2) respectively, links with multiway analog switch (4) again simultaneously; Microprocessor (CPU2) links with display (3); Speech chip (A1) links with power amplifier (6), and speech chip (A2) links by switch (S2) and power amplifier (6) or multiway analog switch (4), and multiway analog switch (4) links with multichannel power amplifier (5); The output of power amplifier (6) and loudspeaker (SPK0) link, and the output of multichannel power amplifier (5) and set of speakers (7) link; Any two (I/O) mouthful line of microprocessor (CPU1) and microprocessor (CPU2) is connected to switch (K1) and switch (K2) simultaneously, switch (K3), switch (K4) and switch (S1) link with any three (I/O) mouthful line of microprocessor (CPU1), it is characterized in that, at auscultation instrument the ox realistic model is arranged in the side, the auscultation point is arranged on the ox realistic model, the auscultation point connects with power amplifier (6), and power amplifier (6) connects speech chip (A1) and speech chip (A2).Loudspeaker corresponding with the line interface of wiring board (sitting in the right seat); Auscultation point respectively has corresponding loudspeaker; The best auscultation point of ox realistic model has 12, can listen to the noise of 15 kinds of different organs.

The beneficial effects of the utility model are: by the simulation auscultation exercise to ox realistic model auscultation point, the situation of simulation ill domestic animal not only vivid but also true to nature allows the student carry out the auscultation exercise with various ill hear sounds or the corresponding physiological location of breath sound; In teacher gave lessons process, it can put the type feature explanation of required ill hear sounds or breath sound and speech form by built-in loudspeaker outward, was shown the frequency of this hear sounds or breath sound simultaneously by frequency indication charactron; When the student carries out the auscultation exercise, may broadcast the voice suggestion of hear sounds or breath sound type feature by outgoing loudspeaker, hear sounds or breath sound are then not outer to be put, the student can be with stethoscope under the indication of physiological location prompting charactron, hear in ill domestic animal corresponding physiological location on one's body, the pronunciation of physiological location and different disease associations are controlled according to the best audition position of various disease correspondence automatically by microprocessor; In the examination process, then maskable falls voice suggestion and physiological location prompting, is controlled oneself to analyze by the student and goes to judge; In addition, also realized the synthetic of hear sounds and decomposed, to the hear sounds of some common disease, by the synthetic of hear sounds with decompose, teacher is with the rank of the noise that has that it's too late of controlling noise flexibly, thereby makes student's feature of these hear sounds on top of.
