Description
Technical Field
The invention relates to the technical field of medical appliances, in particular to a novel stethoscope earplug.
Background
Stethoscopes are important tools for medical staff to perform medical work, and by means of the sound amplifying function of the stethoscopes, a user can know the condition of internal organs of a patient seeking a diagnosis. The stethoscope collects and amplifies the working sound of viscera of the patient by the head, and then transmits the working sound to ears of the user by the auditory tube and the earplug. However, the following disadvantages and drawbacks exist with respect to existing stethoscopes:
first, the design of existing commercially available standard stethoscopes, more considering auscultation and less considering the comfort of the doctor wearing the stethoscopes. Stethoscope ear plugs on the current market are often made of round hard plastic or hard silica gel, are hard, and can cause pain when placed on the ears of medical staff for a long time. The shape of the ear canal is round, which is not in line with the structure of the ear canal of a human body, and is uncomfortable to wear.
Secondly, when the existing stethoscope rotates up and down, the earplug is easy to rub the skin of the auditory canal, and the ear canal is easy to feel painful, distended and even injured, bleeding and inflamed of the external auditory canal of a user after being worn for a long time or frequently.
In addition, the earplug part of the existing stethoscope has no structure of being fixed on the auditory canal, and is easy to fall off in the use process, so that in order to obtain a good auscultation effect, medical staff usually forcefully fixes the earplug on the auditory canal, so as to insert the earplug into a deeper position of the auditory canal, thereby avoiding falling off. In this way, the earplug is inserted into the auditory canal too deeply, so that the auditory canal is extruded, and the auditory canal is damaged.
Furthermore, the stethoscope in the prior art comprises a stethoscope head, a auditory tube and an earplug, wherein the earplug is directly fixed at one end of the auditory tube, the earplug can be rotated only by rotating the auditory tube, the earplug can not rotate 360 degrees relative to the auditory tube, and simultaneously, the earplug can rotate inside and outside, so that the stethoscope in the prior art can only enter an auditory canal through a direct insertion mode and can not be worn through a rotating mode when being worn, and the stethoscope in the prior art has the following defects that: 1. the direct insertion mode has no heuristic effect, is convenient for finding the position of the optimal earplug and is easy to fall off; 2. the direct insertion mode can not meet the physiological anatomical structures of auditory meatus of different human bodies; 3. the direct insertion mode and the auditory canal skin are buffer points, so that the auditory canal skin is easy to damage.
In view of the foregoing, there is a need for a stethoscope earplug that conforms to the structure of the human ear canal, is less prone to damage the ear canal, is comfortable to wear, has a fixation function, and can be rotatably adjusted.
