External auditory canal cerumen flushing device and method based on digital ultrasonic wave

Abstract

The invention provides an external auditory canal cerumen flushing device and method based on a digital ultrasonic wave. An ultrasonic wave generation module in the device is packaged in the front end of a pushing rod to generate the ultrasonic wave; the pushing rod is inserted into a hollow cylinder full of cleaning fluid; under the function of the pushing rod, the cleaning fluid which carries the ultrasonic wave flows out of a flange of the hollow cylinder to flow into an external auditory canal through a liquid gyrator, and cerumen is cleaned to flow out along with the cleaning fluid; after the cleaning fluid flows through the liquid gyrator, the cleaning fluid obtains initial kinetic energy which forms a certain angle with the axial direction of a nozzle of the liquid gyrator, the cleaning fluid can move round and round along the external auditory canal after flowing out of the external auditory canal to prevent the cleaning liquid from directly flowing to eardrum, and the safety and the practicality of the device are improved. The device adopts a digital ultrasonic wave technology, the ultrasonic wave parameter can be duly regulated according to the situation of the cerumen, and cleanliness can be improved by the cleaning of the cleaning fluid which carries the ultrasonic wave. The power of the ultrasonic wave is enhanced, the material of the device and the formula of the cleaning fluid are duly changed, and the device and the method can be popularized to applications including the internal cleaning of a blow-off pipeline, special pipelines and the like.

Description

technical field [0001] The invention belongs to the field of ultrasonic cleaning and medical equipment, in particular to an external auditory canal cerumen washing device and method based on digital ultrasonic waves. Background technique [0002] Cerumen of the external auditory canal, commonly known as "earwax", is a substance secreted by the glands of the external auditory canal. The external auditory canal cerumen is generally divided into dry and wet. Wet cerumen is also called oily earwax. It is not easy to clean itself in the external auditory canal, and it is easy to accumulate together. With the evaporation of water in the cerumen, it will harden and block the earwax. The opening of the external auditory canal, thereby affecting hearing. In addition, infants and young children are also prone to cerumen accumulation due to reasons such as narrow ear canal, strong secretion, muscle relaxation, and weak mandibular joint movement. Therefore, infants and people with oil...

AI Technical Summary

Problems solved by technology

[0005] 1) Ultrasound is coupled with cerumen through the air, so the attenuation is serious, and the efficiency is difficult to optimize;

[0006] 2) The cleaning tube needs to go deep into the ear canal, which is difficult to operate and easily causes damage;

[0007] 3) The exfoliated cerumen is difficult to control and is easy to stay in the external auditory canal, so a second cleaning is required
