External auditory canal cleaning device

Abstract

The invention discloses an external auditory canal cleaning device and relates to the technical field of otological treatment auxiliary appliances. The external auditory canal cleaning device comprises a softening liquid storage box body and an ear entering tube, wherein the softening liquid storage box body is vertically arranged; an inner cavity of the softening liquid storage box body is divided into a power cabin at the bottom and a reflowing type piston cabin located at the upper part of the power cabin; a piston plate is matched with the inner part of the reflowing type piston cabin in a sliding and sealing manner; a screw rod is arranged in the middle of the reflowing type piston cabin in the vertical direction; the top of the screw rod is rotatably connected with the inner cavity of the reflowing type piston cabin; the lower end of the screw rod penetrates through the bottom of the reflowing type piston cabin and extends into the power cabin; the lower end of the screw rod is in rotary and sealed connection with the bottom of the reflowing type piston cabin; the middle of the screw rod penetrates through the piston plate and is in sealed connection with the piston plate through a thread; a stepping motor for driving the screw rod and a storage battery power supply circuit for supplying power to the stepping motor are mounted in the power cabin. The external auditory canal cleaning device can be worn for a long time and can be used for continuously softening earwax; softening liquid is at a continuous replacing state and the softening efficiency is high.

Description

technical field [0001] The invention relates to the technical field of otological medical aids, in particular to an external auditory canal cleaning device for softening and dissolving cerumen. Background technique [0002] Cerumen is a light yellow viscous liquid secreted by the cerumen glands in the skin of the cartilage of the external auditory canal. The cerumen glands are a special sweat gland located in the skin of the external auditory canal with ear hair. Cerumen becomes flakes after drying in the air, but some cerumen is like sticky grease, commonly known as "oil ear". Cerumen has the function of protecting the skin of the external auditory canal and adhering foreign objects (such as dust, small bugs, etc.). Usually, by chewing, opening mouth and other exercises, the cerumen can fall off and be discharged by itself. Cerumen embolism refers to the excessive secretion of cerumen in the external auditory canal or the obstruction of discharge, so that the cerumen accu...

Problems solved by technology

There are various tools for removing cerumen, but the most important softening step, there is no special tool, each softening operation must be dripped for several days, and after softening, find a doctor to rinse

Therefore, it takes time and effort to see a doctor every time and the cost is high, which causes a certain burden to the patient.

For tools for softening cerumen, the more advanced design is the Chinese invention patent with application number 201610735108.4, which proposes a device and method for rinsing cerumen in the external auditory canal based on digital ultrasound, which can improve the efficiency of single rinsing , but its mechanism is complex, the cost is high, and for relatively strong cerumen, it still needs to be washed repeatedly, which still cannot solve the existing problems
