Cardiechema electrocardio micro in-situ synchronous detecting sensor based on MEMS technology

Abstract

The invention relates to a cardiechema electrocardio micro in-situ synchronous detecting sensor based on an MEMS technology. The sensor comprises a shell, wherein the shell is fixedly provided with atransaudient cap, the shell is internally provided with a supporting plate, the supporting plate is provided with an MEMS sonic transducer microstructure, and the MEMS sonic transducer microstructureis composed of a supporting frame, a central mass block, cantilever beams and four varistors; the periphery of the shell is sleeved with a ring of electrocardiographic electrode, and the periphery ofthe electrocardiographic electrode is provided with a ring of sucking disc; the electrocardiographic electrode comprises a flexible conductive substrate of which the top face is designed in a pinpointtype microarray, a metal seed layer and a metal layer are sprayed sequentially on the top face of the flexible conductive substrate, and the back face of the flexible conductive substrate is coated with a conductive silver paste layer. Compared with a traditional echometer or electrocardiogram sensor, the sensor utilizes the MEMS technology to integrate cardiechema and electrocardio, thereby achieving multi-parameter joint analysis and diagnosis of a coronary heart disease, the sensitivity is high, the volume is small, batch processing can be achieved, and the cost is low.

Description

technical field [0001] The invention belongs to a novel biomedical device, in particular to a miniature in-situ synchronous detection sensor for heart sounds and electrocardiograms based on MEMS technology. Background technique [0002] Coronary heart disease, namely coronary atherosclerotic heart disease, is a heart disease in which atherosclerotic lesions occur in the coronary arteries and cause stenosis or occlusion of the lumen of the blood vessels, resulting in myocardial ischemia, hypoxia or necrosis in patients. Coronary heart disease is a major disease that seriously threatens human life and health, and its prevention and treatment is a major public health problem faced by the whole world. At present, the current situation of coronary heart disease prevention and treatment is not optimistic: coronary heart disease, which has become increasingly rampant in the past 10 years, as an important cardiovascular disease, has become one of the most important diseases that ser...

AI Technical Summary

Problems solved by technology

At present, most of the existing high-precision medical equipment for diagnosing coronary heart disease cannot solve the problem of early and accurate diagnosis of coronary heart disease. Comprehensive analysis and diagnosis of coronary heart disease with multiple parameters, let alone timely understanding of the development and changes of coronary heart disease

Diastolic heart murmurs contain a large amount of early pathological information of coronary heart disease, and traditional auscultation is limited by the sensitivity of human hearing and the subjective experience of doctors, which greatly restricts the role of heart sounds in the diagnosis of coronary heart disease
