Abstract

The invention relates to a portable and visual Bluetooth electronic stethoscope capable of separating heart and lung sounds. The traditional stethoscope is difficult to capture some weak and very important biological sounds made by the internal organs of a human body. A heart and lung sound sensor and the input end of an active filter circuit in the portable and visual Bluetooth electronic stethoscope are connected through signals, the output end of the active filter circuit is connected with the input end of a filter interface circuit through signals, the output end of the filter interface circuit is respectively connected with an audio power amplifying circuit and a level switching circuit through signals, the audio power amplifying circuit is connected with earphones through signals, the level switching circuit is connected with a master control unit circuit through signals, and a power circuit provides power for the active filter circuit, the filter interface circuit, the audio power amplifying circuit, the level switching circuit and the master control unit circuit. When selectively and individually hearing the heart or lung sounds, the electronic stethoscope analyzes the heart or lung sounds in real time by means of the Bluetooth wireless connection with a computer.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and relates to a portable medical device for measuring heart and lung sounds, in particular to a stethoscope capable of selectively separating the heart and lung sounds and transmitting the heart and lung sounds to a PC for display, storage and playback. Background technique [0002] Cardiovascular disease has been a major disease that threatens human life for a long time, and it is still one of the main causes of human death. Heart disease is the number one killer of human health. In my country, hundreds of thousands of people die of heart disease every year, and heart disease has been rising rapidly in recent years. The prevalence of cardiovascular diseases and respiratory diseases among the people in our province is increasing year by year. [0003] Among the various detection methods for heart disease, auscultation of heart and lung sounds is the oldest and most commonly used method ...
