Distributed wearable dynamic heart sound collecting device

Abstract

The invention relates to a distributed wearable dynamic heart sound collecting device, which belongs to the technical field of the biomedical signal detection. The distributed wearable dynamic heart sound collecting device consists of five independent heat sound sensors 1-5, a wire 7 embedded in clothes, a signal output interface 6, five sets of independent signal conditioning circuits, a synchro data acquisition card and a heart sound signal processing unit, which are fastened to clothes through a electric corset. The distributed wearable dynamic heart sound collecting device can realize the synchronous dynamic acquisition of the heart sound signals of five areas (the aortic area, the pulmonary valve area, the second aortic area, the mitral valve area and the tricuspid valve area ) of the wearers in the daily state, and has the functions of automatically segmenting heart sounds, detecting heat rate, and calculating the energy-time-frequency of the heart sounds of the detection zones. The distributed wearable dynamic heart sound collecting device can provide integral heart sound information for the diagnosis of heart disease. The distributed wearable dynamic heart sound collecting device can be applied in intelligent clothes for health supervision. The distributed wearable dynamic heart sound collecting device can not only be used for discovering some valve type heart diseases, but also can be used for monitoring the health status of the hearts of the heart patients.

Description

technical field [0001] The invention relates to the field of biomedical signal detection, in particular to a distributed wearable dynamic heart sound detection device, which uses a mechanical structure to fasten five heart sound sensors to specific positions of clothing, and collects heart sounds in five areas synchronously and independently signal, thus providing a device capable of detecting heart sound signals in the daily life of the human body. Background technique [0002] At present, the incidence of heart disease is on the rise year by year, and the younger age of patients makes the early diagnosis of heart disease more and more attention. [0003] At present, commonly used heart disease diagnostic equipment in clinical practice, such as ultrasonic Doppler diagnostic instrument, ECG and other methods, are not only expensive, but also require professional and technical personnel to operate, and usually require experienced professional physicians to analyze the signals...

AI Technical Summary

Problems solved by technology

First of all, the accuracy of heart sound auscultation depends heavily on the experience of doctors; second, abnormal heart sounds are usually sudden and transient, and it is difficult to capture abnormal heart sounds in short-term static auscultation; third, doctors usually use repeated movements during auscultation The stethoscope detects heart sounds in different auscultation areas, and cannot simultaneously detect all auscultation areas and perform comprehensive diagnosis
