Contacting electronic stethoscope capable of avoiding noise interference

Abstract

The present invention relates to one kind of contacting electronic stethoscope capable of avoiding noise interference. The contacting electronic stethoscope has stethoscopy head in the part to be contacted with human body, and inside the stethoscopy head, there are one contacting microphone to receive the sound from human organ and one elastomer outside the contacting microphone to keep the contacting microphone in certain distance from the human body before some pressure is applied to the stethoscopy head so as to avoid friction sound while the stethoscopy head is moved on the surface of human body or clothing.

Description

technical field [0001] The invention relates to a contact electronic stethoscope capable of avoiding noise interference during auscultation, and is applied to receive physiological sound signals generated by human organs. Background technique [0002] Existing stethoscopes include traditional wired stethoscopes and wireless electronic stethoscopes, wherein the principle of receiving digital signals for existing contact-type wireless electronic stethoscopes includes: a stethoscope head in contact with the human body, and a contact microphone is provided inside the stethoscope head; A circuit board, the circuit board includes audio frequency conversion logic circuit, LCD output circuit, output emission circuit, button input logic circuit and function selection circuit, etc. When the auscultation head is placed on the human body, the analog sound emitted by the human body organs is collected by the contact microphone, and then the audio frequency is converted into a digital log...

AI Technical Summary

Problems solved by technology

[0003] The shortcoming of existing contact-type electronic stethoscope, when the stethoscope head of this stethoscope moves on the body or clothing surface, the friction noise that will produce ear-piercing and irrelevant human body information in contact with each other, this will have a strong impact on the hearing of medical staff, and medical staff needs to spend Greater spirit, focus on listening to the subtle sounds of the symptoms and sides, and endure the interference of friction noises

Furthermore, for wireless digital wireless electronic stethoscopes, some signals that have nothing to do with human body information will be received, resulting in the transmission of wrong information.
