Example Embodiment

[0028] The present invention will be further described below with reference to the accompanying drawings.

[0029] 1. Determination of distributed heart sound collection area. There are five commonly used clinical examination areas for heart sounds, and doctors usually consider the heart sounds of these five areas comprehensively. Therefore choose figure 1 The five regions in the present invention are used as the heart sound collection regions in the present invention.

[0030] 2. The fixation of the heart sound sensor, the fasteners such as image 3 shown. On tight-fitting clothing, determine the fastening position of the heart sound sensor so that it corresponds to the heart sound collection area in 1. The protrusions on the fastener shell 9 are placed on the inside of the clothing, and a spring washer 12 is added to the outside of the corresponding clothing. The shell 9 is fixed on the clothing, the screws 11 with the springs 13 on the top are installed, the heart sound...

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...
