After inflating and fixing the laryngeal mask air bag 2, artificial respiration can be carried out according to the laryngeal mask mode, and then fix the hand-held handle of the mask tube body 1 according to the condition of the patient. Handle 16, the other hand pushes the airway tube 4 deeply inward, the airway tube 4 will pass through the glottis and enter the trachea, and the depth of the airway tube 4 can be determined according to the scale difference between the two indicating scale lines. When in the position, the airway air bag 5 is inflated to close the trachea through the first inflation and deflation device 7, and after confirmation, artificial respiration is performed in the endotracheal catheter ventilation mode, as shown in Figure 1. At this time, in order to alleviate the bad compression of the laryngeal mask airbag 2 on the pharynx, the laryngeal mask airbag 2 can be properly deflated, and then the laryngeal mask can be withdrawn or not withdrawn according to the needs of the patient's condition. After the laryngeal mask airbag 2 is inflated, the airway airbag 5 is deflated and then carefully retracted according to the method of advancing the airway 4 until the airway 4 returns to the mask body 1 to change to the laryngeal mask ventilation mode. If the condition requires not to keep the laryngeal mask, you can exit the ventilation mode in which the laryngeal mask retains the pure endotracheal tube as follows, remove the universal tube connector 16, insert the first 7 inflation and deflation devices into the rear end of the airway tube, and fix the airway tube 4. Slowly and carefully pull out the laryngeal mask outward with the other hand, and then fix the airway tube 4 to perform the endotracheal tube ventilation function. In short, the two ventilation modes can be changed at once according to the needs of the condition, so as to ensure the safety of the patient and improve the work efficiency of the doctor.
