Background technique

Nasal adhesion is one of the complications after nasal sinus endoscopic surgery, and it is also a common complication after nasal trauma. Clinically, in order to prevent this complication, it is necessary to repeatedly place Vaseline oil gauze strips in the nasal cavity to separate the nasal cavity On the one hand, the setting of oil gauze can easily cause nasal ventilation obstruction, decrease lung function through nasal pulmonary reflex, and decrease arterial oxygen saturation, which will cause patients to suffer from breathlessness, dyspnea, dry throat, and affect eating and sleeping On the other hand, nasal cavity drainage disorder easily causes infection and causes mucosal healing to be delayed; therefore people have designed a nasal cavity stent for placing nasal cavity adhesions, but the existing nasal cavity stent has the following deficiencies in actual use:

1. During the use of the existing nasal cavity stent, because the nasal cavity stent is directly inserted into the nasal cavity, there is a lack of firmness in the fixation, and when facing children, the nasal cavity stent is small and easy to be swallowed;

2. The existing nasal cavity stents only play the role of avoiding nasal cavity adhesion during use, but such nasal cavity stents cannot be applied to patients with dyspnea, and their practicability is poor;

Therefore, it is necessary to improve the prior art to solve the above technical problems.
