Auditory meatus cleaning device

Abstract

The invention discloses an auditory meatus cleaning device, relating to the field of medical devices for the ear-nose-throat department. According to the auditory meatus cleaning device, the external auditory meatus is cleaned through method of superposing the pulse liquid flushing and elastic fiber bundle rubbing. During cleaning, first, a plugging bag capable of realizing air inflation expansion blocks the auditory meatus in front of the eardrum at the deep position of the external auditory meatus, so that the impact injuries caused to the eardrum by liquid are prevented. On one hand, the washing effect of the pulse liquid can be fully exerted, on the other hand, the pulse liquid drives the elastic fiber bundle to have elastic deformation; in the processes of generating elastic deformation and resetting, the elastic fiber bundle generates the repeated rubbing effect with the inner wall of the auditory meatus, then, due to the superposing of the liquid washing and the direct contact of the elastic fiber bundle, the cleaning effect is better than that of the independent washing and scraping adopting a hard material, and meanwhile, the injuries caused to the auditory meatus are greatly reduced.

Description

technical field [0001] The invention relates to the technical field of ear, nose and throat medical instruments. Background technique [0002] Preoperative preparation is very important for external auditory canal and middle ear surgery. When the external auditory canal or middle ear is diseased, there will be secretions or other diseased tissues in the external auditory canal. Therefore, on the premise of understanding the disease, preoperative preparations are necessary to prevent bleeding or loss of diseased tissue due to traction and stimulation of the diseased tissue (especially for malignant tumors). Tumors) cause adverse consequences, which is particularly critical. Therefore, cleaning the ear canal is an extremely important part in the preoperative preparation. The existing ear canal cleaning device mainly includes a flushing method and a negative pressure suction method. The flushing method uses liquid medicine that can soften the secretion to flush the ear canal...

AI Technical Summary

Problems solved by technology

The washing method uses liquid medicine that can soften the secretion to wash the ear canal; the pure washing method is better for small and viscous secretions, but the effect is not obvious for oily secretions or larger secretions

The negative pressure suction method uses a straw to suck out the secretion. Due to the poor visibility of the ear canal, the operation is time-consuming and laborious.

[0003] For the cleaning of the ear canal, the method of direct contact and scraping is used, which has a good cleaning effect, but it is easy to cause damage to the external auditory canal, and it is not easy to perform this method in a narrow space with existing operating instruments
