Description

Noise-reducing ear-protecting stethoscope

Technical Field

The utility model relates to the field of medical treatment, specifically a ear protection stethoscope of making an uproar falls.

Background

The stethoscope is the most commonly used diagnostic tool for internal and external gynecologists, is the mark of the physicians, and the modern medicine is the invention of the stethoscope. The device mainly comprises a sound pickup part, a conduction part and a listening part, and is used for collecting and amplifying sound emitted from the heart, the lung, the artery, the vein and other internal organs. The stethoscope effect is commonly seen in-ear headphones, i.e. the earplug cord or unit is subjected to external impact or air friction, and the generated vibration is directly transmitted into the ear canal through the earplug cord, thereby generating unpleasant sound. The rear-hanging earphone can greatly improve the stethoscope effect.

The stethoscope is a necessary tool of doctors, can be used for listening to heart rate, heart sound, blood vessel noise and the like, but the sound pick-up can generate friction noise with the skin of a human body in the moving process, and the noise interferes with the diagnosis of the doctors. The stethoscope, which is an indispensable instrument for auscultation, plays a decisive role in the whole auscultation process. The stethoscope generally has high environmental requirements during use, and is generally used in a relatively quiet room. When in a noisy environment, a doctor is often required to find a quieter environment, which causes time waste and inconvenience to medical staff and patients. The existing stethoscope has large noise when in use, which affects the correct judgment of the doctor on the illness state, and the auscultation head has poor sound taking effect, low usability and inconvenient operation. The common stethoscope is hung on ears when being reused, needs medical care personnel to hold the stethoscope by hands, but cannot well examine a patient by a single hand, so that the stethoscope is very inconvenient to examine.
