Minisize pick-up head 10 is arranged in ventilation tube chamber 3, and minisize pick-up head 10 is connected with data and power line 11.
Wherein, interface 1 of ventilating is located at outside nasal cavity, plays a part of to limit nasopharyngeal air duct setting position.Ventilation tube chamber 3 one
End outside is provided with scale, and scale starts sign from 10cm with the other end of tube chamber 3 of ventilating as starting.
Ventilation tube chamber 3 one end is provided with the foldable structure 4 of adjustable length.The ventilation inwall of tube chamber 3 is provided with vertically a blind hole
8, the one end of steel wire 7 is ferrule arrangement, and the other end of steel wire 7 insertion blind hole 8, ferrule arrangement is reached outside ventilation interface 1.Pharynx end 2
For round and smooth structure, it is to avoid damage nasopharyngeal cavity when stretching into nasopharyngeal cavity.The ventilation inwall of tube chamber 3 is provided with vertically gas port 9, gas port 9
One end connects with cuff gas injection port 5, and the other end is connected with cuff 6.
Ventilation length 0-20cm of tube chamber 3, the indexing from 10cm, 10cm, 10.5cm, 11cm, 11.5cm ... 20cm, its
Middle 14cm-20cm adopts adjustable and retractable, during enforcement, 14mm-20mm is when foldable structure is fully deployed, in placement process
In, if patient without n and V, choke and cough, ventilation is good, and registered depth is fixed on nasopharynx airway device at nostril, reality
The principle of existing nasopharyngeal air duct individuation.
Ventilation tube chamber 3 other end is provided with cuff 6, plays a supporting role, and cuff 6 is shaped as three-dimensional wave, sees Fig. 2,
By cuff gas injection port 5 to the gas injection of cuff 6, the space of pars oralis pharyngis can be increased, be more beneficial for ventilation.
The scalable using method with cuff nasopharyngeal air duct device, comprises the following steps：
1) steel wire 7 is inserted into blind hole 8, then nasopharyngeal cavity is inserted in the Jing sides nostril of pharynx end 2 of ventilation tube chamber 3, swallow the circle at end 2
Slipped Clove Hitch structure do not damage it is pharyngeal on the premise of, smoothly will ventilation tube chamber 3 be placed in nasopharyngeal cavity, according to scale judge ventilation tube chamber 3
Built-in length；
2) inflated to cuff 6 by cuff gas injection port 5, if patient feels ventilation tube chamber 3 not in place, by cuff gas injection
Mouth 5 is deflated to cuff 6, and then proceeding to force makes pharynx end 2 stretch into nasopharyngeal cavity, until patient feels ventilation tube chamber 3 in place, breather pipe
Chamber 3 is inflated to cuff 6 afterwards in place, makes ventilation tube chamber 3 be fixed on nasopharyngeal cavity, then takes out steel wire 7；
If 3) until ventilation interface 1 is resisted against at nostril, patient still feels to ventilate tube chamber 3 not in place, then hand-held steel wire 7
Ferrule arrangement to pharynx end 2 exert a force, using steel wire 7 extend foldable structure 4, until ventilation tube chamber 3 in place, inflate to cuff 6, make
Ventilation tube chamber 3 is fixed on nasopharyngeal cavity, then takes out steel wire 7.
4) during if nasopharyngeal cavity is inserted in the Jing sides nostril of pharynx end 2 of tube chamber 3 of ventilating, need to observe bottleneck throat, utilize
Minisize pick-up head 10 in ventilation tube chamber 3, is delivered to bottleneck throat image outside ventilation tube chamber 3, by data line end by data wire
The connection display terminal of usb 12 in portion, realizes accurately showing the position of nasopharyngeal air duct in placement process, keeps patient respiration
Road it is unobstructed.
The utility model is adopted by cuff gas injection port 5 to after the gas injection of cuff 6, and cuff 6 can play a supporting role, and expands mouth
Pharyngeal space, will not increase the external diameter of ventilation tube chamber 3, be more beneficial for ventilation；Cuff gas injection port 5 is stretched from the ventilation side wall of tube chamber 3
Go out, cuff 6 is kept apart with ventilation tube chamber 3, do not interact when nasopharyngeal air duct is inserted.This apparatus structure is simple, cavity
Unimpeded, ventilation contact surface is big, simple to operate, and little to patient trauma, its front end will not stimulate the epiglottis of patient and glottis, it is to avoid disease
There is reflux and inhale by mistake in people, reduce because inducing laryngospasm using nasopharyngeal air duct, and the situation for threatening patient vitals' safety occurs.
