Problems solved by technology

[0003] Heart sound is a method for monitoring the state of the heart and for early detection and diagnosis of heart diseases; currently, doctors use a stethoscope to explore and listen to a certain area of ​​the chest when listening to heart sounds, and then find the best heart sound listening position, and the best listening position Judgment marks are only based on the sound heard by the doctor subjectively and the professional experience of the doctor, without forming a specific and exact graphic or data form, and objectively judge the best listening position through graphic or data comparison; in addition, It is impossible to listen to heart sounds in different regions at the same time and obtain the results of the first to fourth heart sounds at the same time. The location and location of the first to fourth heart sounds are also different. The strength of the heart sounds in each region and the final waveform image can be judged. Early diagnosis of heart lesions in the area; now patients need to go to the hospital for early examination of heart sounds if they need to do a professional early examination of heart sounds. There is no portable heart sound monitoring equipment, so that patients can do it at home at any time Monitoring heart sounds can enable early detection and early treatment of some heart diseases; in the future, some home medical care will be developed, and early monitoring and examination of some patients' own health conditions can be carried out at home

Embodiment 1

[0037] refer to Figure 1 to Figure 2 As shown, an intelligent heart sound pickup, monitoring, and positioning system equipment is characterized in that the main hardware includes: an electrode sheet 1, a signal transmission line 2, a splitter 3, a center console 4, a display screen 5, and a button controller 6;

[0038]The electrode sheet 1 has four sheets, and a piezoelectric film sensor is installed in the electrode sheet 1. The piezoelectric film sensor of the model LDT0-028K can be selected, which has good flexibility. The piezoelectric film of 28 μm is used, and the signal transmission line 2 Connected to the integrated circuit board; the piezoelectric film sensor is very sensitive to the pressure applied to it, when a small force is regularly and intermittently applied in the longitudinal direction of the film, a large stress will be generated in the transverse direction, and if a large area is applied to the film in the transverse direction for a long time The stress g...

Abstract

The invention discloses intelligent heart sound picking, monitoring and positioning system equipment. The intelligent heart sound picking, monitoring and positioning system equipment is characterizedin that main hardware comprises electrode slices, signal transmission lines, a deconcentrator, a center console, a display screen and a key controller; the equipment can automatically find out the optimal heart sound hearing position through system operation; and a first heart sound, a second heart sound, a third heart sound and a fourth heart sound can be heard.

Description

technical field [0001] The invention belongs to the field of biomedical signal monitoring, in particular to an intelligent heart sound picking, monitoring and positioning system equipment. Background technique [0002] Heart sound is the mechanical vibration caused by factors such as myocardial contraction and relaxation, valve closure, and blood flow impacting the ventricular wall and aorta during the cardiac cycle, which is transmitted to the chest wall through the surrounding tissues. The sound heard; the heart sound is divided into the first heart sound, the second heart sound, the third heart sound and the fourth heart sound; the first heart sound is produced by the mitral and tricuspid valves; the second heart sound is produced by the aortic valve and It is produced by the closure of the pulmonary valve; the third heart sound is produced by the sudden deceleration of the blood flow from the atrium into the ventricle when the ventricle is rapidly filling in the early di...
