Problems solved by technology

[0003] However, the current acoustic stethoscope has defects in removing friction noise. When the sensing cavity head of an ordinary acoustic stethoscope is in contact with the human body or the clothes worn by the human body, it will generate horizontal friction noise, which will mix with the longitudinal physiological sound generated in the human body. overlap, which interferes with the doctor's diagnosis

Abstract

The invention provides an anti-noise stethoscope which comprises a sensing cavity, a sound transmitting pipeline and earplugs which are sequentially connected. The sensing cavity comprises a shell, an annular hose is clamped to the inner side of an opening of the shell, the annular hose is made of an inflation rubber pipe, an annular wall is also clamped to the inner side of the annular hose, the outer wall of the annular wall makes direct contact with the annular hose, the front end of the annular wall is covered with a pickup film which is an elastic resin film, and the annular wall and the pickup film are integrally formed through a pickup film material. The anti-noise stethoscope can lower transverse friction noise of the sensing cavity, reduces interference and facilitates auscultation.

Description

Technical field [0001] The invention relates to the field of medical equipment; specifically, it is a stethoscope. Background technique [0002] Stethoscope is the most commonly used diagnostic tool for doctors in medical equipment, and it is an essential tool for doctors. In terms of cardiovascular, it can be used to listen to heart rate, heart sounds, vascular murmurs, etc., and to measure blood pressure. The breathing sound of the lungs can be used to identify lung lesions; it can also be used to auscultate the heart sounds of the fetus, etc.; a stethoscope is necessary for identifying vital signs such as heartbeat and blood pressure. [0003] However, the current acoustic stethoscope has defects in removing friction noise. When the sensing cavity head of an ordinary acoustic stethoscope is in contact with the human body or the clothes worn by the human body, it will generate horizontal friction noise, which will mix with the longitudinal physiological sound generated i...
