Description
Technical field
The utility model relates to the field of medical instrument technology, specifically, being a kind of modified form nasopharyngeal air duct.
Background technique
Nasopharyngeal air duct, as the term suggests it is exactly the air passage of via intranasal application placement, the same oropharyngeal airway of use scope, but stimulation
Small, nauseous response light easily fixes, and patient end has side port, and the overstriking of gas circuit end can prevent from sliding into nasal cavity.Nasopharyngeal air duct is maximum
The characteristics of be also do big advantage be manipulation it is simple, using, effectively, slightly training can be controlled, can in seconds or
In the twinkling of an eye complete operation, after can effectively ventilate.Nasopharyngeal air duct has wide range of applications, and is mainly used in is anaesthetizing at present
Section, Respiratory Medicine etc. help patient to carry out unimpeded respiratory tract, consequently facilitating the progress of medical operating etc..
But there are following not foot points for existing nasopharyngeal air duct at present: often during being placed in patient's nasal cavity,
Cause to contact with each other on the inside of air flue tube body and patient's nasal cavity because of unreasonable structure, causes patient uncomfortable；The merging of air flue tube body is suffered from
Depth in person's nasal cavity can not be grasped, and the judgement of medical staff is influenced；Nasopharyngeal air duct is rear without very in merging patient's nasal cavity
Good fixed structure, air passage ontology are easy to slide, and cause to repeat the phenomenon that setting pipe, and air flue tube body is easy to cause pneumatic duct to exist
It is moved in nasal cavity, influences the effect of ventilation, will increase the feeling of pain of patient for a long time.
