Abstract

The invention provides a nasal cavity implant and an application thereof. The nasal cavity implant comprises a main body which comprises a connecting end and a free end; and the connecting end comprises at least one meshing part and a fillet terminal. In a direction from the connecting end of the main body to the free end, an included angle between the surface, closest to the main body, of the meshing part and the outer wall surface of the main body is alpha, wherein the alpha is greater than or equal to 10 degrees and less than or equal to 90 degrees. When being implanted in the nasal cavitytissue, the nasal cavity implant has a relatively good capability of being meshed with the nasal cavity tissue on the premise of ensuring a relatively good slow-release effect (slow and stable releaseof drugs can be realized and an efficient treatment effect can be achieved with a relatively small dose), so that the nasal cavity implant can be prevented from being discharged out of the body together due to sneezing or rhinorrhea.

Description

technical field

[0001] The invention belongs to the field of medical equipment, and relates to a nasal cavity implant and its application. Background technique

[0002] The main clinical manifestation of allergic rhinitis is sneezing, with paroxysmal attacks several times a day, each time more than 3. There are foreign articles reporting that the general airflow velocity of a sneeze is 150 km / h, which is 41.7 m / s. The foam is sprayed three or four meters away, which is almost close to the central wind force of a 15-level typhoon. The general way of administration is nasal cavity or nasal passage administration, but this way of administration will be excreted together when sneezing or runny nose, so no good therapeutic effect can be achieved.
