Problems solved by technology

Multi-slice spiral CT can clearly display the coronary arteries and judge the stenosis of the lumen. Although it is non-invasive, it is damaging. The rays generated by CT scanning will cause harm to the human body, and the high cost of inspection is not suitable for early general screening

Embodiment Construction

[0017] The inventive device such as figure 1 As shown: it includes heart sound signal detection module 1; ECG signal detection module 2; multi-channel synchronous A / D conversion module 3; data processing module 4; human-computer interaction module 5.

[0018] The signal output terminals of module 1 and module 2 are connected to the signal input terminal of module 3; the DMA channel of module 3 is connected to the signal input terminal of module 4; the signal output terminal of module 4 is connected to module 5. Place the five piezoelectric sensors in the above-mentioned heart sound signal detection module 1 in five different parts of the front chest wall of the human body, respectively: for males, place them in the second intercostal space on the right edge of the sternum in the order of the first to fifth channels , the second intercostal space at the left sternal border, the third intercostal space at the left sternal border, the fourth intercostal space at the left sternal ...

Abstract

The invention discloses a device for detecting the coronary artery stenosis of a human body, wherein, the device can detect parameters relative to the coronary artery stenosis in a noninvasive and nondestructive manner. The device adopts the method that five heart sound signal sensors are arranged at five different parts of an anterior chest wall so as to monitor heart sound signals, an electrocardiosignal detection electrode is arranged on a wrist of the right hand and the lower parts of ankles of two feet or is arranged on the wrists of two hands and the lower part of the ankle of a right foot so as to detect electrocardiosignals, a controller is used for controlled so as to lead a multi-channel synchronous A / D (Analog to Digital) conversion module to convert five heart sound signals that are acquired synchronously and the electrocardiosignals, converted signals are sent to a data processing module for data processing module, and the parameters relative to the coronary artery stenosis are obtained.

Description

technical field [0001] The invention relates to a device for detecting coronary artery stenosis in a non-invasive and non-destructive manner. Background technique [0002] Myocardial ischemic heart disease caused by coronary artery stenosis (Coronary Artery Stenosis, CAS) is commonly referred to as coronary heart disease (Coronary Artery Heart Disease, CHD). Its incidence rate is increasing at a rate of 20% per year, and it is gradually getting younger. If effective treatment cannot be carried out in the early stage of the disease, it will lead to myocardial ischemic necrosis or even death. Early detection of coronary artery stenosis and evaluation of the degree of stenosis are effective means for early warning and diagnosis of coronary heart disease. Currently, coronary angiography (Coronary Angiography, CAG) is still recognized as the "golden indicator" for detecting coronary artery stenosis. It can more clearly reveal the anatomical deformity of the coronary artery and...
