Description

new stethoscope earplugs

technical field

The utility model relates to the technical field of medical instruments, in particular to a novel stethoscope earplug.

Background technique

The stethoscope is an important tool for medical staff to perform medical work. With the help of the stethoscope's loudspeaker function, the user can understand the condition of the internal organs of the patient. The stethoscope collects and amplifies the working sound of the patient's internal organs through the listening head, and then transmits it to the user's ear through the listening tube and earplugs. Yet there are following deficiencies and defectives about existing stethoscope:

First of all, the design of existing commercially available standard stethoscopes considers the auscultation effect more and seldom considers the comfort level problem of the doctor wearing the stethoscope. Currently on the market, the earplugs of stethoscopes are often made of circular hard plastic or hard silicone. The earplugs of stethoscopes are relatively hard, and when they need to be placed on the ears of medical staff for a long time, the medical staff will feel sore. Its shape is mostly round, which does not conform to the structure of the human ear canal and is uncomfortable to wear.

Secondly, when the existing stethoscope is rotated up and down, the earplugs tend to rub against the skin of the ear canal, and long-term or frequent wearing can easily cause the user to feel ear canal pain, swelling, and even damage, bleeding, and inflammation of the external auditory canal.

In addition, the earplug part of the existing stethoscope has no structure fixed to the ear canal, and it is easy to fall off during use. In order to obtain a good auscultation effect, medical personnel usually fix the earplug on the ear canal by force, so as to insert the earplug into a deeper position in the ear canal. thereby avoiding falling off. In this way, the position of the earplug inserted into the ear canal is too deep, which will squeeze the ear canal and cause ear canal damage.

Furthermore, the stethoscope in the prior art includes a listening head, a listening tube and an earplug, wherein the earplug is directly fixed on one end of the listening tube, and only the rotating listening tube can rotate the earplug. This makes the stethoscope in the prior art can only enter the ear canal by in-line insertion when worn, and cannot be worn by rotation. The stethoscope in the prior art enters the ear canal by in-line insertion and has the following disadvantages: 1. In-line insertion The method does not have a tentative effect, it is easy to find the best earplug position, and it is easy to fall off; 2. The direct insertion method cannot meet the physiological and anatomical structure of the ear canal of different human bodies; 3.
