Stethoscope for department of cardiology

Abstract

The invention discloses a stethoscope for a department of cardiology. The stethoscope comprises a detecting body and an outer sleeve, the detecting body is in a cylindrical shape, the outer sleeve isarranged at the upper end of the detecting body in a covering mode, the outer sleeve and the detecting body are fixedly connected through connecting springs, and a flexible connecting method facilitates isolation of sound wave transmitting and further plays a buffering function when the stethoscope falls down to the ground; and a vacuum cavity is formed in the outer sleeve, and the function of thevacuum cavity is to further isolating sound to reduce interference of handholding of medical personnel towards detection. According to the stethoscope for the department of cardiology, the structureis simple and reasonable, loss of the sound wave in the transmitting process is reduced, meanwhile, the outer sleeve and the detecting body are fixedly connected through the connecting springs, the flexible connecting method facilitates isolation of the sound wave transmitting and further plays the buffering function when the stethoscope falls down to the ground, interference of signals sent by electronic equipment towards the stethoscope is reduced, the precision of the detection is improved, illness condition diagnosis by the medical personnel is facilitated, and the practicability is high.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a cardiology stethoscope. Background technique [0002] The stethoscope (stéthoscope) is the most commonly used diagnostic tool for internal and external gynecologists and children, and is a symbol of doctors. Modern medicine began with the invention of the stethoscope. Since the stethoscope was used clinically on March 8, 1817, its shape and sound transmission method have been continuously improved, but its basic structure has not changed much, mainly consisting of the sound pickup part (chest piece), the conduction part (rubber tube) and the listening part. (Earpieces) Composition. [0003] The main function of the pickup is to collect auscultation sound, which is equivalent to a "microphone". Amplifying and filtering device is then " speaker ", auscultation sound is amplified. The processing chip is used to reduce the interference of noise and ensure the ideal sou...
