Embodiment Construction

[0018] The present invention aims to propose a method, and in this method, some hardware devices that are not available on the market need to be used. In order to prove the feasibility of the method, in the implementation case, the preparation scheme of the hardware device required by the method is a and presented.

[0019] The preparation scheme of the in vivo detection module: the shape of the in vivo detection module is long, and its internal circuit includes two pressure sensors (distributed at both ends of the module), a wireless communication transmitting circuit, a wireless charging receiving circuit, and a temporary storage unit for electric energy (such as a capacitor) , the module is wrapped in a biocompatible shell. Among them, the miniature pressure sensor, wireless communication transmitting circuit, wireless communication receiving circuit, and electric energy temporary storage unit are all mature technologies, so they will not be repeated here. The module conta...

Abstract

The invention relates to a method for detecting vessel stenosis based on double interventional pressure sensors. According to the method for detecting the vessel stenosis based on double interventional pressure sensors, the two pressure sensors are guided into a blood vessel (mainly the artery blood vessel) in an interventional mode, and whether stenosis happens to the blood vessel between the two pressure sensors can be judged by measuring the numerical values of the two pressure sensors through calculation.

Description

technical field [0001] The invention relates to a method for detecting vascular lumen stenosis in the medical field. Background technique [0002] At present, there are at least 230 million cardiovascular patients in my country, and 200 million hypertensive patients. Among many cardiovascular diseases, the morbidity and mortality of coronary heart disease are extremely high and have increased rapidly. From 1998 to 2008, the incidence of coronary heart disease in Chinese men The incidence rate will increase by 26.1% compared with the same period in the past, and the female will increase by 19.0%. The main cause of coronary heart disease is that some lipids accumulate in the arterial intima to form white plaques, resulting in narrowing of the arterial lumen, blocking blood flow, leading to cardiac ischemia and angina pectoris. In general, patients with coronary heart disease often undergo cardiac stent interventional surgery. In 2011, there were 408,000 cases of cardiac stent ...
