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 device of the present invention such as figure 1 Shown: Including 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. The five piezoelectric sensors in the heart sound signal detection module 1 are placed on five different parts of the front chest wall of the human body. They are: For men, they are placed in the second intercostal space on the right edge of the sternum in the order of the first to the fifth. , The second intercostal space on the left side of the sternum, the third intercostal space on the left side of the sternum, the fourth intercostal space on the left side of ...

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] Coronary Artery Stenosis (CAS) caused by myocardial ischemic heart disease is often referred to as Coronary Artery Heart Disease (CHD). The incidence rate is increasing at a rate of 20% per year and is gradually becoming younger. If effective treatment is not carried out in the early stage of the disease, it will lead to myocardial ischemic necrosis and even death. Early detection of coronary artery stenosis and evaluation of the degree of stenosis are effective methods for early warning and diagnosis of coronary heart disease. At present, Coronary Angiography (CAG) is still recognized as a "golden index" for detecting coronary artery stenosis. It can more clearly reveal the anatomical deformities of the coronary arteries and the location, extent and scope of their obstructive lesions. However, because the ...
