When the device is used, the front section of the ventilation catheter 1 is placed into a trachea through a glottis, after intubation is completed, the ventilation catheter 1 is communicated with the ventilation interface 3 in a sealing mode, the ventilation interface 3 is connected with a breathing machine or an anesthesia machine, the ventilation interface 3 and the ventilation catheter 1 form a sealed ventilation pipeline which is communicated with the trachea and the lung of a patient, and the device can support the respiration of the patient. The airway tube 1 is now partially located within the trachea and partially within and outside the mouth above the glottis. The inner cavity of the head end of the ventilation catheter 1 is provided with an atomizing nozzle 12 which is positioned at the deep part in the tracheal cavity, and a medicine feeding interface 13 at the middle rear part of the ventilation catheter 1 is positioned outside the oral cavity. Corresponding to the general anesthesia patient to be treated, the spontaneous respiration is interrupted by the muscle relaxant, and the patient is in a mechanical support respiration state. When the medicine needs to be administered to the deep part of the air passage and the lung, the medicine is sucked by the injector, the medicine is hermetically connected with the injector through the medicine administration interface 13, the push rod of the injector is pushed, the medicine in the injector reaches the atomizing nozzle 12 through the atomizing medicine administration pipe 11, and the medicine is injected into the deep part of the air passage and the lung after atomization through the medicine outlet of the atomizing nozzle 12, so that the related treatment is completed. The corresponding therapeutic diseases are mainly: bronchospasm, asthma, COPD, and the like.

It should be reminded that in order to increase the therapeutic effect of the drug, the administration is preferably completed in an inspiratory state, at this time, the air bellow of the anesthesia machine pushes the oxygen-rich gas into the lung, the direction of the airflow in the air bellow is to pass through the air flue to the small air flue and the air alveoli deep in the lung, the drug is pushed, and the atomized drug enters the deep part of the air flue and the air alveoli under the driving of the airflow, so that the administration part can be accurately reached, and the best therapeutic effect is achieved.

It should be added that, clinically, many doctors have a habit of spraying local anesthetic under glottis and glottis when intubating, and the beneficial effects are that the local anesthetic can anaesthetize the surface of the glottis and the upper airway, increase the tolerance of the tracheal catheter entering the airway, reduce the intubation reaction and reduce the pain of the patient caused by the tracheal catheter when the patient is awake.
