Abstract

The nasal cavity stent comprises a stent body, the stent body is of a tubular structure, a spray irrigation channel with an open end and a closed end is integrally formed in the annular side wall of the tubular structure, the open end is used for being connected with a spray and suction source, and spray and suction holes are formed in the side wall of the spray irrigation channel. According to the scheme, the characteristics of the nasal cavity support are ingeniously utilized, the nasal cavity support is not limited by a nasal threshold and a special structure, all-directional flushing, dosing, dirt suction and other operations are carried out on mucosa in the nasal cavity, on one hand, operation and control are convenient, on the other hand, nasal cavity irrigation and suction of special parts become possible, the nasal cavity flushing removal rate is increased, and the nasal cavity cleaning efficiency is improved. According to the technical scheme, accurate drug delivery of special parts is achieved, and the novel nasal cavity internal medicine intervention device is a brand new technical scheme for nasal cavity internal medicine intervention, is particularly suitable for treatment of diseases such as infection and allergy of the nasal cavity, the nasopharyngeal cavity and the eustachian tube, is also suitable for treatment in the nasal cavity mucosa perioperative period after a nasal operation, promotes mucosa recovery and prevents adhesion and relapse.

Description

technical field [0001] The present disclosure relates to the technical field of medical devices, and in particular, to a nasal cavity support and a nasal cavity irrigation system. Background technique [0002] Nasal diseases in otolaryngology, such as chronic rhinosinusitis-nasopharyngitis, adenoid hypertrophy or deviated nasal septum, have a high incidence, which seriously affects the quality of life of patients, and also affects many ears, pharynx and lower airways. The cause of the disease, due to blockage and abnormal anatomical structure, makes the drug treatment time too long, and it is not easy to completely eliminate the inflammation and prolong it into chronic. Complications of nasal adhesions may occur after surgery. Nasal adhesions will cause obstruction of airflow at the lesion site, inflammation will not subside, resulting in recurrence of the disease, and some residual blood and purulent secretions are likely to remain in the surgical cavity. After cleaning, s...
