The heater 35 is arranged above the atomizing cavity 33, and the bottom of the atomizing cavity 33 is provided with the ultrasonic transducer 30.

In the practical use process, firstly the injector 31 inhales the anesthetic, then the anesthetic is injected into the atomizing cavity 33 through the spiral tube 32, the ultrasonic transducer emits high-frequency oscillation, then a small amount of anesthetic in the atomizing cavity 33 is oscillated to form anesthetic liquid drops in an atomized state, the anesthetic liquid drops are heated to form gaseous anesthetic after passing through the heater 35, and finally the gaseous anesthetic liquid drops are mixed with oxygen in the oxygen delivery tube to achieve induction of anesthetic gas.

By adopting the anesthetic gas generation mode, the anesthetic gas is generated at a high speed, the anesthetic gas is prevented from being liquefied in the conveying process, the influence on the accurate administration of the anesthetic is avoided, and the operation is more convenient; in addition, because anesthetic at first injects into the atomizing chamber through the spiral pipe, visual operation can be carried out to the volume of anesthetic like this, and the quantity is accurate, all can inject into the accurate dose in atomizing chamber at every turn, avoids taking place danger.

In the system of this embodiment, the solenoid 32 is cylindrical, and the solenoid 32 is provided with scales to facilitate visual measurement of the medicament. A connection hose 310 is disposed between the syringe 31 and the spiral tube 32.
