Abstract

The invention discloses an electronic stethoscope based on an n-type cantilever beam type one-dimensional MEMS acoustic sensor, and belongs to the technical field of biomedical devices. The electronic stethoscope comprises a supporting threaded connector, a heart sound probe shell and an MEMS acoustic sensor microstructure, wherein the supporting threaded connector is composed of a triangular supporting frame, a supporting column, a fastening bolt, a sliding block, a connecting rod, a supporting plate and a supporting rod, the heart sound probe shell is composed of an oval shell, a cover body and an induction film, and the MEMS acoustic sensor microstructure is arranged in the heart sound probe shell. The electronic stethoscope is scientific in design, reasonable in structure, small in size, attractive, low in cost, easy to machine, easy to produce in batches, convenient and stable to use and operate, high in detection sensitivity, high in anti-jamming capability, high in signal-to-noise ratio, high in reliability, high in bandwidth, good in detection effect and worthy of popularization and application.

Description

technical field [0001] The invention belongs to the technical field of biomedical devices, and in particular relates to an acoustic sensor probe for detecting heart sound signals, in particular to an n-type cantilever beam-based sensor probe which specifically converts heart sound signals and has strong anti-interference ability and high reliability. Electronic stethoscope with dimensional MEMS acoustic sensor. Background technique [0002] The heart sound signal is one of the most important active physiological acoustic signals of the human body. It is formed by the contraction and relaxation of the myocardium during the beating process of the heart, the opening and closing of each valve, and the vibration generated by the movement of the myocardium and blood. It includes various parts of the heart such as the atrium A large amount of physiological information of the heart, ventricle, cardiovascular system, great vessels and various valves can reflect the normal or patholog...
