Ear canal inflammation medicine feeder for otology and laryngology

Abstract

The invention discloses an ear canal inflammation medicine feeder for otology and laryngology. According to the medicine feeder, two sides of an inflammation position are sealed, air is blown into a local ear canal, and fed medicines are uniformly diffused. The medicine feeder is characterized in that a sealing and retaining ring is arranged at on end of a hollow silica gel sealing head, the other end of the silica gel sealing head is of a hemisphere structure, a circular groove is formed in the outer side wall of the silica gel sealing head and positioned at one end of the sealing and retaining ring, the circular groove is a trapezoid groove, a plurality of speed reduction strips are arranged in the circular groove in an equal angle manner and hung at a half position of the depth of the circular groove and extend along an axis of the silica gel sealing head, a plurality of jet holes are peripherally and equidistantly formed in the circular groove, communicated with the inside of the silica gel sealing head and in one-to-one correspondence to the speed reduction strips, the widths of openings of the jet holes are radially and gradually increased, a plurality of fixed rings are equidistantly arranged on the inner wall of the silica gel sealing head, and a plurality of grooves are formed in the inner wall of the silica gel sealing head.

Description

Problems solved by technology

[0002] At present, in medical clinical treatment, ear inflammation is often encountered, and it is necessary to apply medicine to the inflammatory site to reduce inflammation. However, due to the complicated structure of the ear canal and the narrow space, it is difficult for the medicine to be delivered directly to the lesion. The existing liquid medicine uses drip The medicine is carried out in the way of medicine, the medicine has a short action time and flows in the ear canal, which affects the hearing. The medicine is poorly targeted and the medicine is wasted. The medicine is delivered in the ear canal, and the medicine is applied to the inflammation site. Because the material of the cotton swab is hard, the cotton will stick to the wound, hurt the inflammation area, and affect the wound healing. And some medicines enter the ear canal and fit the eardrum, causing hearing loss, and some appliances are reused, resulting in cross-infection of the wound;

[0003] Publication No. CN105997343A discloses an ear canal powder drug delivery device, which includes an ear canal insertion tube, a drug delivery container, a nebulizer, and a drug delivery tube; One end of the ear canal insertion tube is connected to the drug delivery tube, and it is characterized in that the other end of the ear canal insertion tube is provided with a cotton tip, and the ear canal insertion tube on the side of the cotton tip is provided with a medicine outlet hole; the device is made of plastic material for ear canal insertion The tube is provided with a cotton head and a medicine outlet hole. The powder medicine is administered into the dosing tube through the metering valve, and the powder medicine is sprayed into the ear canal through the sprayer, and then spread evenly through the cotton head. The sprayer blows the powder into the ear canal through the airflow. Directly impact and attach to the ear canal, causing secondary damage to the wound site, affecting wound healing, and the coating of the cotton head will come into contact with the inflammation site again, and the extrusion is severe, making the powder adhered and falling off, and the inflammation area cannot be fully treated Applying the medicine, the direction of applying the medicine is open, the medicine will directly extend into the ear canal under the action of the airflow, and contact the eardrum to cause hearing failure
