Delivered to the nostrils of the patient, the patient can breathe through the nostrils.

Specifically, as shown in Fig. 1, when the time for the patient to take off the ventilator training is shorter (this time is determined by the specific situation of the patient, in the medical work, the doctor can usually judge how long it is a short time or a long time) time), the oxygen supply device 1 is directly connected to the endotracheal tube 4 through the oxygen inhalation tube 5. At this time, due to the short time, air humidification may not be required, and the oxygen inhalation tube 5 is used as a simple oxygen supply Tube. Referring to Fig. 2, when the patient takes a long time to take off the ventilator for training, both the oxygen supply device 1 and the humidification device 2 are connected to the endotracheal tube 4 through the three-way tube 3, and the endotracheal intubation The tube 4 delivers the oxygen-containing and humidified mixed gas output from the oxygen supply device 2 and the humidification device 3 to the patient's body; that is, the oxygen supply device 1 delivers air containing a certain amount of oxygen to the In the three-way tube 3, the humidification device 2 humidifies the air in the three-way tube 3, and finally the three-way tube 3 transports the humidified air into the endotracheal tube 4, and then enters the patient in vivo. Of course, at this time, the oxygen supply device 1 and the three-way tube 3 or the endotracheal tube 4 and the three-way tube 3 may be connected through the oxygen inhalation tube 5 . Referring to Fig. 3, when the off-breather training is successful, the oxygen supply device 1 is connected to the patient's nostril position through the oxygen inhalation tube 5, so that the patient performs breathing training through the nostril, that is, the oxygen inhalation tube 5 It is used to connect the oxygen supply device 1 to the patient's nostril airway, so that the patient can gradually restore the function of nostril breathing, that is, one end of the oxygen inhalation tube 5 is connected to the oxygen supply device 1, and the other end is connected to the oxygen supply device 1. to the patient's nostrils so that the patient can perform breathing exercises through the nostrils.

It should be noted that due to the relationship between the positions and distances between the various components, a connecting pipe can be provided between two interconnected parts as required.
