Operation principle of the present utility model and work process: 1. apply at patient's epistaxis, nasal cavity postoperative only
During the situation of blood:
Patient takes seat or semireclining position, is removed by nasal cavity blood clot as far as possible, uses containing tetracaine and furan fiber crops cotton
Sheet shrinks nasal membrane, row local anesthesia.Can be coated with wipe at nasopharynx part air bag 2 and nasal cavity airbag 3 surface
Blood medicine or placement soluble stanching gauze.This apparatus is sent into nasopharynx part through Ipsilateral nasal cavity meatus nasi communis.See
Examining central authorities' breather 1 scale to indicate, insertion depth about 10～13cm, direct oral cavity is swallowing rear wall it can be seen that be
Accurate.
Using employing common medical syringe as filling exhaust apparatus, its injection port end insertion spring is filled row
Air valve, backs down valve, through airway, nasopharynx part air bag 2 injects air 10～20ml so that it is full.
Then central authorities' airway is pulled back, nasopharynx part air bag 2 is moved choana to fixing to pulling.Make again
Through airway, nasal cavity airbag 3 injected air 30～40ml with injector for medical purpose so that it is full.According to patient
Bleeding, observes nasopharynx part pressure detecting air bag 6 and the force value of nasal pressure detection air bag 9, suitable
Air in increase and decrease nasopharynx part air bag 2 and nasal cavity airbag 3, reaches good haemostatic effect, reduces simultaneously
Patient's sense of discomfort；Finally the nose outer portion immobilization with adhesive tape of this apparatus is completed in Face and cheek, hemostasis.
Intubate latter 48 hours, if stopped bleeding, be i.e. ready for tube drawing.First by nasopharynx part gas before tube drawing
Air in capsule 2 and nasal cavity airbag 3 is extracted out, observes whether nasal cavity stops hemorrhage.The most again conduit is pulled out
Going out, final confirmation is stopped blooding successfully.For the patient of hemorrhage ferociousness, can divide 2～3 times and extract nasopharynx part air bag out
2 and nasal cavity airbag 3 in air, be gradually lowered the air bag contention effect to petechia, reach stop blooding purpose.
Owing to central authorities' breather hardness is moderate, will not cause blocking ventilation because of pressurized.If owing to nasal cavity divides
Secretion or blood clot cause obstruction, can terminate suction pump, removed outside central authorities' breather 1.
For needing the patient of oxygen uptake, Oxygen tube can be terminated outside central authorities' breather 1, it is ensured that patient's oxygen uptake
Demand.
2. apply at nostril forming postoperative:
According to the postoperative requirement of nostril forming, select nasopharynx part air bag 2 or nasal cavity airbag 3 as postoperative auxiliary
Bracing frame, for nostril plastic expansion.After nasal membrane local anesthesia, in central authorities' breather 1 graduated scale
Know, under auxiliary, this apparatus is inserted deep nasal cavity, the air bag of selection is filled.Expand according to postoperative nostril plasticity
The needs opened, adjust the force value of air bag, reach dilatation Choanal by observing pressure detecting air bag
Purpose, it is to avoid postoperative scar contracture.Finally by the nose outer portion immobilization with adhesive tape of this apparatus in Face and cheek.
Owing to central authorities' breather 1 does not affect normal nasal airflow, inserting after this apparatus can band pipe for a long time.With
Time can understand air bag to nostril dilating effect effect by the force value of routine observation pressure detecting air bag,
Increase and decrease air through Air inflating and exhausting valve if desired, adjust the pressure of air bag.Fully meet the postoperative needs of nostril forming
Long-time support expands requirement.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all
Within spirit of the present utility model and principle, any modification, equivalent substitution and improvement etc. made, all
Within protection domain of the present utility model should be included in.
