Anterior naris stent

Abstract

The invention relates to an anterior naris stent. The anterior naris stent comprises an annular stent body provided with central ventilating holes and a nose clip which is connected with the annular stent body, wherein the annular stent body is formed into a conical structure which is stuffed into an anterior naris and is provided with a large end and a small end; the annular stent body comprisesa first side wall; the nose clip is connected with the first side wall and extends out of the annular stent body from the large end; the nose clip is formed into an arc curved hook which is matched with the outer side wall of the anterior naris; the tail end, facing the small end, of the arc curved hook is arranged close to the first side wall and is provided with an arc fold away from the first side wall. The anterior naris stent provided by the invention can be mainly used for treating a single-sided nasal cavity, and the annular stent body having the conical structure can be conveniently inserted into the anterior naris, and the nose clip can be clamped on the outer side wall of the anterior naris so as to prevent the annular stent body from being sucked into the depth of the nasal cavity, and the nose clip is stably mounted at the front end of a nasal limen.

Description

technical field [0001] The present disclosure relates to the field of medical devices, in particular, to an anterior nostril stent. Background technique [0002] Nasal breathing occupies a relatively large proportion of the human respiratory system, but the existing nasal cavity diseases will cause nasal congestion to a certain extent, resulting in poor nasal ventilation. For example, a deviated nasal septum will affect the patient's respiratory function, making the patient Difficulty breathing. In addition, nasal congestion can also cause various injuries to the human body, such as chronic hypoxia, affecting the cardiovascular and cerebrovascular systems of the human body, and affecting the quality of sleep of patients; it can also cause damage to the lower airway of the human body; it can even cause The poor drainage of the sinuses leads to the occurrence of rhinosinusitis, causing the clinical symptoms of headache and purulent nasal discharge. In short, nasal congestion...

AI Technical Summary

Problems solved by technology

At present, the main methods to improve nasal ventilation are surgery and drug treatment. However, with the aging of the population, some patients do not want surgery, are afraid of surgery, or have surgical contraindications and cannot undergo surgical treatment, and drug treatment cannot fully satisfy patients.
