Description

Technical Field

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

[0002] In the prior art, among ear diseases, secretory otitis media is a common and frequently occurring disease, which is a type of non-suppurative otitis media. For patients with recurrent secretory otitis media, due to the poor function of their Eustachian tube, the drainage of the tympanic cavity is poor, resulting in negative pressure and effusion in the tympanic cavity, which leads to hearing loss and even more serious sequelae such as adhesive otitis media. The treatment of non-suppurative otitis media requires the placement of a ventilation tube on the tympanic membrane to balance the pressure inside and outside the tympanic cavity and to remove the effusion in the tympanic cavity. The T-type tympanic membrane ventilation tube used in hospitals in the past is safe due to its long tube length, but it is prone to tube blockage and is not easy to remove the tympanic cavity effusion after tube placement. If it is cut for use, it is easy to fall into the tympanic cavity and poses a safety hazard. Although the tympanic membrane ventilation tube currently available on the market can reduce the risk of tube falling off to a certain extent during use, its fixation effect is poor, and due to its simple long tube design, the incidence of tube blockage in clinical applications is high.

[0003] The Chinese utility model patent with application number: 202021310160.3 discloses an anti-clogging tympanic membrane ventilation tube, including an outlet tube and a tentacle, the outlet tube and the tentacle are fixed in a T shape, the tentacle is fixed to the inner end of the outlet tube, and the inner end is the end extending into the patient's body; the tentacle is arranged in a strip shape, and its inner side surface is a groove surface, the groove surface includes a recessed area in the middle and convex areas on both sides, the recessed area and the convex area are both arranged along the axial direction of the tentacle, and the recessed area extends to the end of the tentacle; the interior of the outlet tube is a hollow part, and the hollow part is a diversion channel. The inner end of the hollow part passes through the tentacle until it is connected with the recessed area, so that the drainage channel is connected with the hollow part, and the inner end of the hollow part is exposed at the outer end of the outlet tube; a through hole is provided in the radial direction of the outlet tube. However, although this type of anti-clogging tympanic membrane ventilation tube can limit the ventilation tube and the tympanic membrane in one direction through the tentacle structure, it does not have a positioning structure, resulting in a poor positioning effect of this type of ventilation tube. If the external pressure of the tympanic membrane suddenly increases, the tympanic membrane ventilation tube will fall into the tympanic cavity and create a safety hazard. In addition, the overall structure adopts an integrated design. If any part is damaged, it will cause the entire structure to be scrapped, and the economic benefits are low. Utility Model Content
