Abstract

The invention provides an electronic stethoscope which comprises an upper shell (1) and a lower shell (2). A stethoscope diaphragm (3) is fixed to the lower shell (2) and used for making contact with a human body to conduct heart sounds or lung sounds. A sensor (4) is placed in the space defined by the upper shell (1) and the lower shell (2) and used for converting the heart sounds or lung sounds into electric signals. The stethoscope is connected with an external terminal in a wireless or wired mode. The electronic stethoscope is characterized in that the stethoscope is connected with the external terminal in a Bluetooth wireless mode, heart sound or lung sound signals are upwards transmitted to the external terminal by means of a Bluetooth RFCOMM channel, signal fidelity is improved, and diagnosis is easy.

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 advantages of auscultation can be realized with simple, low-cost and easy-to-use devices, it will be of great practical value. In the prior art, electronic stethoscopes have occurred, but their complex structure and high cost are not enough for use. convenient. Contents of the invention [0003] In order to overcome the defects of the prior art, the present invention proposes an electronic stethoscope capable of...
