Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a combined tympanic membrane ventilation tube structure. Background Art

[0002] In the prior art, among ear diseases, secretory otitis media is a common disease and a frequently-occurring disease. For patients with recurrent secretory otitis media, due to the poor function of their Eustachian tube, the tympanic cavity drainage is not smooth, forming tympanic cavity negative pressure and (or) effusion, thereby leading to hearing loss, and even more serious sequelae such as adhesive otitis media. Tympanic membrane ventilation tubes are often needed in the treatment of secretory otitis media. Surgical implantation of tympanic membrane ventilation tubes is an important means to drain the effusion in the tympanic cavity, balance the pressure inside and outside the tympanic cavity, and improve tympanic cavity ventilation. The T-type tympanic membrane ventilation tubes used in hospitals in the past have safety due to their long tubes, but they are prone to tube blocking and are not easy to remove the tympanic cavity effusion after the tube is placed. If they are cut and used, they are easy to fall into the tympanic cavity and have safety hazards. Although the tympanic membrane ventilation tubes currently available on the market can reduce the risk of tube falling off to a certain extent during use, they are usually one-piece structures and are relatively single in use, and cannot be flexibly adjusted and used according to the patient's condition.

[0003] Chinese Utility Model Patent Application No. 201520065364.8 discloses a tympanic ventilation tube comprising at least a tube body and a baffle disposed at one end thereof, the baffle having a through hole communicating with the hollow cavity of the tube body; a side hole formed in the wall of the tube body near the other end, at least two of which are symmetrically arranged on either side of the tube body, each of which is trapezoidal in shape; side wings formed in the wall of the tube body near the baffle, at least two of which are symmetrically arranged on either side of the tube body, each of which is U-shaped in cross-section and opens toward the side hole; the diameter of the tube body gradually increases from the baffle to the side hole; the baffle is provided with an inverted L-shaped antenna, which is perpendicular to the baffle, and the baffle is elliptical in shape. However, this tympanic ventilation tube is a one-piece structure, which results in a relatively simple usage method and cannot be flexibly adjusted according to the patient's condition. In addition, the tube body is short in length, which cannot effectively drain secretions from the tympanic cavity. Utility Model Content
