Description
Technical field
This utility model relates to field of medical, specifically a kind of intelligent online formula hear sounds collection analysis device.
Background technology
Hear sounds is one of physiological signal of wanting of body weight for humans, be in cardiac cycle due to myocardium contraction and diastole, the keying of valve, blood flow impacts the faint sound that vibration that the factors such as ventricle wall and large artery trunks cause is sent; Also increasing sharply and reducing the vibration forming of its rigidity that is cardiac muscle under periodic electrocardiosignal effect, arrives through ambition conducting system the body surface sound that thoracic wall forms.Listening to of hear sounds is a kind of basic skills of clinical assessment systema cariovasculare functional state.Produce in physiology or pathomorphology change at some cardiovascular system diseases, the various noises that hear sounds occurs and distortion are important diagnostic messages.Hear sounds diagnosis and detection is an important means understanding heart and cardiovascular system state.It will be further appreciated that, hear sounds has important value in cardiovascular disease, is the important method of the non-invasive detection of cardiovascular disease, has the advantage that electrocardiogram, ultrasound cardiogram are not replaced.Therefore, the extraction to hear sounds and analysis will have great significance.Signal record in hear sounds the more indistinguishable useful informations of a large amount of people's ears, it is a kind of complex sound signal being formed by Multiple components, traditional auscultation with stethoscope analytical method is subject to clinician's experience and subjective judgment, this measure diagnosis mainly depends on doctor's experience level, can only be often experienced cardiologist, just can make correct diagnosis.And the clinician that universal experience level is not too enriched feels worried for this reason.The hear sounds collection analysis device that there is no at present intellectual analysis type can be identified more abnormal hear sounds.
Utility model content
Utility model object: the problem and shortage existing for above-mentioned prior art, the purpose of this utility model is to provide a kind of intelligent online formula hear sounds collection analysis device, can auscultation and the cardiechema signals of acquisition and known cardiechema signals are analyzed, identify abnormal hear sounds; Can also obtain online hear sounds analysis result in online upgrading hear sounds storehouse.
Technical scheme: for realizing above-mentioned utility model object, the technical solution adopted in the utility model is a kind of intelligent online formula hear sounds collection analysis device, comprise heart sound transducer, signal amplification circuit, photoelectric isolating circuit, interfering signal stripper, microcontroller, memorizer and display device, described heart sound transducer gathers cardiechema signals, process cardiechema signals through described signal amplification circuit, photoelectric isolating circuit and interfering signal stripper successively again, and signal after treatment is inputted to described microcontroller, described microcontroller is connected storage and display device also.Wherein, signal amplification circuit is for amplifying the cardiechema signals that heart sound transducer collects and the cardiechema signals after amplifying being transferred to photoelectric isolating circuit, photoelectric isolating circuit is for preventing surging signal and the abnormal external magnetic field electric field interfering signal of the front end of circuit own, can guarantee that like this signal gathering is undistorted, the signal of output is transferred to interfering signal stripper by photoelectric isolating circuit, interfering signal stripper is used for removing noise and the noise of the cardiechema signals receiving, and signal after treatment is transferred to microcontroller.Because the storage space volume that microcontroller carries is too small, this utility model adopts special memorizer for storing known cardiechema signals and corresponding disease type, microcontroller contrasts the cardiechema signals receiving (the disease type that known cardiechema signals is corresponding is clear and definite) with known cardiechema signals, the type of the disease that the cardiechema signals that obtains receiving is corresponding, as room lacks, chamber lacks, and quivering etc. in chamber, can in display device, show.If hear sounds is normal, cardiechema signals is converted into hear sounds curve or electrocardiogram picture or word by microcontroller, in display device, shows.
Further, also comprise wireless network card and server, described microcontroller and wireless network card wired connection, described wireless network card and server wireless connections.Because the memory span being connected with microcontroller can not be too large, and the disease that in reality, different cardiechema signals is corresponding is of a great variety, sometimes the cardiechema signals of memory stores cannot be corresponding with the cardiechema signals receiving, at this moment microcontroller sends to by wireless network card the cardiechema signals receiving the server of far-end, in server, store the cardiechema signals of magnanimity and corresponding disease type, by server, the cardiechema signals receiving is contrasted and draws the type of the disease that the cardiechema signals that receives is corresponding with the cardiechema signals of its storage, result is returned to microcontroller and show in display device, simultaneously data in new memory more, when receive same cardiechema signals next time again like this, the direct consults memory of microcontroller, without again by wireless network card and server communication.
Further, also comprise loudspeaker, described loudspeaker connect microcontroller.As previously mentioned, microcontroller can not only show the type of disease in display device, can also send chimes of doom by loudspeaker; As hear sounds is normal, play hear sounds by loudspeaker.
Further, also comprise band filter, the input of described band filter connects the outfan of signal amplification circuit, and the outfan of band filter connects the input of photoelectric isolating circuit.The object of band filter is only to allow the signal of hear sounds frequency range to pass through, and prevents that irrelevant signal from entering in system.For example patient's arm that rubs sometimes, produce sound, but the cardiechema signals of not wanting should not enter in system yet.
Further, also comprise analog-digital converter, the input of described analog-digital converter connects the outfan of photoelectric isolating circuit, and the outfan of analog-digital converter connects the input of interfering signal stripper.Because the cardiechema signals of heart sound transducer collection is generally analogue signal, and microcontroller needs processing digital signal, therefore adds that analogue signal is converted to corresponding digital signal by analog-digital converter.
Further, also comprise control panel, described control panel connects microcontroller.Control panel can be controlled the switch of microcontroller etc.
Further, described display device is for showing and touch screen.Can select by touch the content of screen display, as selected to show hear sounds curve or electrocardiogram picture under normal condition.
Further, described microcontroller is ARM processing controller, and speed is fast.
Beneficial effect: this utility model can auscultation and the cardiechema signals of acquisition and known cardiechema signals are analyzed, and identifies abnormal hear sounds; Can also obtain online hear sounds analysis result in online upgrading hear sounds storehouse, make automatically to obtain auscultation result and become a reality.
