The electromagnet A14 is controlled to be powered off, due to positive pressure ventilation of an air compression pump at an air flow inlet 20, air flow pushes away the air suction flap 12, the respirator 1 is communicated with the medicine storage bottle 1, continuous air flow introduced by the air compression pump passes through an air outlet hole in the top of the air inlet pipe 2, under the blocking of the atomizing cup cover, an air channel is formed at a narrow groove 6 in the periphery of the air inlet pipe 2, the bottom of the narrow groove 6 is communicated with the medicine storage groove, high-speed air flow formed by the air channel passes through the medicine storage groove to drive medicine liquid in the medicine storage groove to be atomized to form droplet particles, and then the air suction flap 12 is pushed away to enter the respirator 1 and reach a breathing nozzle through the air suction port 10. The breathing nozzle is contained in the mouth of a patient, and the gas enters the respiratory tract of the patient so as to achieve the purpose of treatment.

When the patient exhales, the pressure sensor 13 senses the pressure change in the respirator (the pressure is increased compared with the last moment), the pressure sensor 13 senses that the patient inhales, the controller 23 receives the signal of the pressure sensor 13, the electromagnet A14 is controlled to be powered on, the inhaling valve 12 is closed, and the respirator 4 is isolated from the medicine storage bottle 1.

The invention greatly improves the utilization rate of the medicine, greatly reduces the medicine waste, shortens the medication time of the patient, accelerates the recovery of the patient, lightens the medical expense burden of the patient and the hospital cost, and avoids the waste of the national medical insurance. The invention utilizes the valve device and the high-sensitivity trigger device to carry out pressure support drug delivery, so that patients with respiratory insufficiency can carry out atomization treatment, and the dyspnea of the patients during the atomization treatment is relieved. The invention is particularly useful for treating respiratory diseases.
