Electronic stethoscope

Abstract

The invention discloses an electronic stethoscope. The electronic stethoscope comprises an upper shell (1) and a lower shell (2), wherein a stethoscope membrane (3) is fixed on the lower shell (2) and is used for touching a human body and transmitting heart sound or lung sound; a cavity cover (6) is tightly connected with the lower shell (2); the cavity cover (6) and the stethoscope membrane (3) encircle to form a sound collection cavity; a sound transmission device (4) is arranged in the sound collection cavity and is fixed on the cavity cover (6); a through hole (62) is formed in the cavity cover (6), so that the interior of the sound collection cavity is communicated with the exterior; the stethoscope further comprises an isolation cover (7); the isolation cover (7) covers the exterior of the cavity cover (6); a channel for communicating the through hole (62) with the outside is reserved; the upper shell (1) and the lower shell (2) are fixedly connected together; airflow is communicated with the outside via a pressure releasing hole (12) in the upper shell (1); the structures such as a pressure releasing channel and the isolation cover and the like are arranged, so that the inner air pressure intensity and the outer air pressure intensity of the stethoscope can be balanced; the noise is isolated; the sensitivity and the signal-to-noise ratio of the stethoscope can be improved.

Description

technical field [0001] The invention belongs to the field of medical instruments, in particular to an electronic stethoscope. Background technique [0002] Heart disease and respiratory system disease are major diseases that seriously threaten human health and life. Auscultation is an important method for detecting heart and respiratory diseases, and has incomparable advantages over other methods. However, there are many deficiencies in the traditional stethoscope, which hinder the development of medicine in the diagnosis of heart sounds or breath sounds. If the advantage of auscultation can be realized with simple, low-cost and easy-to-use devices, it will have great practical value. The existing electronic stethoscope occurs in the prior art, but its structure is complicated, the cost is higher, and the use effect is not good. needs improvement. Contents of the invention [0003] In order to overcome the defects of the prior art, the present invention proposes an elec...
