Example Embodiment

figure 1 It is the circuit schematic diagram of the portable visual heart sound auscultation teaching system. The heart sound sensor 1 collects the human heart sound signal, and then sends it to the preamplifier 2 for primary amplification of the signal, then sends it to the 50Hz trap circuit 3 to filter out 50Hz power frequency interference, and then passes through the high / low pass filter circuit 4 to filter out more than 1000Hz respectively High-frequency noise and low-frequency noise below 10Hz, the filtered signal is sent to the main amplifier circuit 5 for secondary signal amplification, and then sent to the high-speed A / D converter 6, which converts the analog signal into a digital signal and sends it to the high-speed micro The processor 7 analyzes the heart sound signal. The high-speed microprocessor 7 analyzes the envelope, ARMA, and CWD of the read-in digital heart sound signal respectively, and after obtaining the corresponding data, sends it to the SD card 9 to st...

Abstract

The invention discloses a portable type visualized cardiophony teaching system, which is formed by a cardiac sound collection and transmission module, a microprocessor, an earphone and a touch screen, wherein the cardiac sound collection and transmission module comprises a cardiac sound sensor, a prepositioned sensor, a 50-Hz trap circuit, a high/low-pass filtering circuit, a main amplifying circuit and an A/D (Analogue/Digital) converter, which are connected in sequence; the microprocessor is respectively connected with a storing device, an LED (Light-Emitting Diode) lamp, a network card, a USB (Universal Serial Bus) interface and a power supply managing module; the microprocessor is internally provided with an operating system; the operating system comprises an onsite cardiac sound collection module, a case learning module, a learning effect testing module and a user managing module; and the onsite cardiac sound collection module comprises a cardiac sound collection sub-module, a cardiac sound analyzing sub-module, an authority judging sub-module and a cardiac sound storing sub-module. The system disclosed by the invention has the characteristics of small volume, convenience for carrying, and capability of representing different cardiac sounds to a user on two aspects of auditory sense and visual sense, can carry out onsite cardiac sound collection and learning effect test, and is convenient for being promoted and popularized in school teaching.

Description

Technical field [0001] The present invention involves portable visual visual aiology system, which is convenient for promoting and popularizing in school teaching. Background technique [0002] Among the many physiological signals of the human body, the heart sound signal is one of the most important voice signals of the human body. It contains a large amount of pathological information about the function of various parts of the heart such as atrium, heart chamber, large blood vessels, cardiovascular, and valve.The most basic parameter of the state is a reflection of the condition of the heart and large vascular machinery.Before cardiovascular disease has not developed to produce clinical and pathological changes (such as changes in ECG), the murmur and distortion in the heart sound is important diagnostic information.What's more worth mentioning is that heart sounds have important value in cardiovascular diseases. It is an important method for cardiovascular disease to conduct n...
