Sliding and locking in 403.In addition, air guide pore 405 is additionally provided in lip stopper 4, in order to which above-mentioned gas-guide tube 6 passes through.
For the ease of providing source of oxygen for airflow channel 103, the oxygen supply end 102 of guiding tube 1 has connection dismountable
Standard breath return circuit joint 3, the oxygen supply end 102 of guiding device can also be connected with ventilator in the prior art.
In use, the air bag 5 is in a deflated state, guide device of endotracheal tube is inserted in trachea cannula, trachea cannula
Inlet 101 is slightly longer than trachea cannula, while oxygen supply end 102 is connected source of oxygen, to a certain extent to the inflation of air bag 5
Afterwards, it is fitted close tracheal catheter and tracheal catheter guider, is not loosened.The tracheal catheter guider one of tracheal catheter will be housed
Insertion patient throat is played, lip stopper 4 is blocked in the patient's mouth, tracheal catheter guider crooked radian is adjusted by drawing pull ring 201,
To be adapted with the pharyngeal anatomical structure of patient, thus accurate intubation rapidly.
After the completion of trachea cannula operation, open the air valve 701 in sphygmomanometer inflatable ball 7, air bag 5 becomes smaller, trachea cannula with
Gap between guide device of endotracheal tube becomes larger, to smoothly remove guide device of endotracheal tube.It is always patient in whole process
Oxygen supply, particularly for the patient of difficult airway, trachea cannula difficulty increases, and needs the intubation of long period, no longer repeatedly
The operation that tube drawing oxygen uptake is intubated again is carried out, to mitigate the damage to the pharyngeal soft tissue of patient, and timely logical for patient as early as possible
Gas, as far as possible reduction patient's deaeration time.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on should be included in the utility model
Protection scope within.
