External ear cleaning device for nursing in otolaryngology department

Abstract

The invention relates to the technical field of external ear cleaning devices for otorhinolaryngology department nursing, in particular to an external ear cleaning device for otorhinolaryngology department nursing, which comprises a tube body, a pressing rod and a spray pipe, the pressing rod is mounted in the tube body, the spray pipe is fixedly connected to one side of the tube body, a mounting block is fixedly connected to the surface of the tube body, and by pressing a movable plate, the spray pipe is fixedly connected to one side of the tube body. Second rotating shafts on the two sides are driven to move, a movable strip rotates through a first rotating shaft to push a limiting plate, the limiting plate slides in a first sliding groove through a first sliding block, the limiting plate slides on the inner wall of a semicircular block, and a first magnet is driven to move through movement of the movable plate; the first magnet and the second magnet are attracted together, the movable plate and the semicircular block form a circle shape through the limiting plate, fingers placed on the mounting block are clamped, it is guaranteed that when a pipe body is used, taking and placing are firmer, and the situation that when an external ear is cleaned, the hand shakes, and consequently the pipe body falls off can be avoided.

Description

technical field [0001] The invention relates to an external ear cleaning device for ENT nursing, in particular to an external ear cleaning device for ENT nursing. Background technique [0002] The external auditory canal is a curved tube extending from the external auditory door deep in the concha cavity to the inside to the tympanic membrane, which can conduct the sound waves collected by the ear to the tympanic membrane. Due to the inclined position of the tympanic membrane, the outer 1 / 3 of the external auditory canal is based on the cartilage of the external auditory canal, which is a cartilaginous external auditory canal, and the inner 2 / 3 is based on bone and is a bony external auditory canal. The junction of the two is narrow; The narrowest part of the external auditory canal is called the isthmus, which prevents foreign bodies from entering the external auditory canal and injuring the tympanic membrane. External auditory canal cartilage and auricle cartilage are con...

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides an external ear cleaning device for ENT nursing, which overcomes the deficiencies of the prior art, has a simple structure design, and effectively solves the problem of the existing external ear cleaning device for ENT nursing. When using, when cleaning the ear canal, since it is operated by hand, it is necessary to clamp the fingers to ensure the stability of the hand operation and avoid falling. At the same time, different ear canals have different sizes , it is necessary that the cleaning plate can be telescopically moved, so that it can fit the ear canal and improve the cleaning efficiency
