Embodiment Construction

[0031] The specific embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present disclosure, but not to limit the present disclosure.

[0032] In the present disclosure, unless otherwise stated, the used directional words such as "inner and outer" refer to the inner and outer sides relative to the contour of the corresponding component itself, and the used directional words such as "front and rear" refer to After the nasal stent is placed in the nasal cavity, the end close to the nostril is the front, and the end that goes deep into the nasal passage is the back. Terms such as "unloaded state" are used to refer to the state of the nasal stent when it is not compressed and fully relaxed, "first", "second", etc. are used to distinguish one element from another and are not sequential and important sex. ...

Abstract

The nasal cavity stent comprises a stent body, the stent body comprises a tubular structure formed by connecting an outer membrane and an inner membrane, the tube wall of the tubular structure comprises a closed area and an expansion area, a spraying and sucking pipe is clamped among the closed area, the outer membrane and the inner membrane, and spraying and sucking holes are formed in the side wall of the spraying and sucking pipe in a penetrating mode. Through holes are correspondingly formed in the outer film. According to the scheme, by means of the characteristics of the nasal cavity support, 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, nasal cavity irrigation and suction of special parts become possible, the nasal cavity flushing removal rate is increased, accurate dosing of the special parts is achieved, and the nasal cavity support is convenient to use. The technical scheme is a brand-new technical scheme for medical intervention in the nasal cavity, is particularly suitable for treating diseases such as infection and allergy of the nasal cavity, the nasopharynx cavity and the eustachian tube, is also suitable for treating the nasal cavity mucosa perioperative period after the 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 the blockage and abnormal anatomical structure, makes the drug treatment time too long, and it is difficult to completely eliminate the inflammation and prolong the chronicity. 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 cleanin...
