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

technical field [0001] The invention relates to a device for applying medicine to inflammation of the ear canal in the department of otolaryngology, relating to a device for applying medicine to inflammatory wounds in the ear canal during the treatment of inflammation of the ear canal in the department of otolaryngology, and belongs to the field of medical devices. In particular, it relates to a device for blocking both sides of the inflammation, blowing air locally on the ear canal, and evenly diffusing medicine. Background technique [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.

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;
