A water-adding pipe 6 and an air outlet 7 are arranged in the water-adding and air-outletting chamber 4. The liquid medicine chamber 5 is used to hold liquid medicine and an ultrasonic atomizing plate 9 is arranged at the bottom of the liquid medicine chamber 5. The ultrasonic atomizing plate 9 can atomize the liquid medicine. The height of the liquid medicine added to the liquid medicine chamber 5 is lower than the height of the vent hole at the lowest position of the partition 3, that is, the vent hole at the lowest position of the partition 3 is at a preset height from the bottom of the liquid medicine chamber, and the preset height is the maximum height of the liquid medicine that can be added. The second shell 2 is provided with an atomizing nozzle 10 connected to the liquid medicine chamber 5, and the atomizing nozzle 10 is provided with a nasal air inlet tube 11. When in use, the nasal air inlet tube 11 is placed at the patient's nostrils.

The water delivery component includes a water storage tank 8, a water outlet pipeline 15 and a water outlet nozzle 12 which are connected in sequence with a water filling pipe. The water outlet nozzle 12 is arranged on the first shell 1, and the water outlet nozzle 12 is connected in sequence with a drinking hose 13 and a mouthpiece 14. When in use, the patient holds the mouthpiece 14 to drink water. The water outlet pipeline 15 is provided with a light sensing element 16 for detecting whether there is water flowing through the water outlet pipeline 15. When the patient holds the mouthpiece 14 to drink water, the water in the water storage tank 8 enters the patient's oral cavity through the water outlet pipeline 15. At this time, the light sensing element 16 is used to detect whether there is water flowing through the water outlet pipeline 15 to determine whether the patient swallows and drinks water. When there is a swallowing action, the Eustachian tube will be opened, and this is the best time to take the medicine.
[0039] The air intake assembly includes an air intake pipeline 18, a compression pump 19 and a compressed air outlet pipeline 22 connected in sequence, and the compressed air outlet pipeline 22 is connected to the air outlet 7; the air outlet of the compression pump 19 is provided with a three-way 21, the first interface of the three-way 21 is connected to the air outlet of the compression pump 19, the second interface of the three-way 21 is connected to the compressed air outlet pipeline 22, and the third interface of the three-way 21 is connected to a pressure detection pipeline 23; the pressure detection pipeline 23 is connected to the control element 24, and is used to detect the outlet pressure of the compression pump 19.

After the water flows through the two light sensing elements 16 of the water outlet pipe 15, the light sensing element 16 transmits the monitored water flow signal to the control element 24 through a wire, and the control element 24 transmits it to the compression pump solenoid valve 20 through a wire to control the compression pump 19 to open; the opening time and opening pressure of the compression pump 19 are controlled by the control element 24, and the outlet pressure of the compression pump 19 is monitored through the pressure sensing pipe 23 next to the tee.
[0043] The compression pump 19 delivers compressed air of preset pressure to the water-added air outlet bin 4, and then flows to the medicine liquid bin 5 on the other side through the air vents on the partition 3. Driven by the compressed air, the medicine liquid atomized by the ultrasonic atomization plate 9 is discharged into the patient's nostrils through the atomization nozzle 10 and the nasal air inlet tube 11, so as to realize swallowing → opening the Eustachian tube → atomizing the medicine from the nasal cavity based on the opened Eustachian tube, so as to achieve the effect of treating middle ear and Eustachian tube diseases.
[0044] The advantages of the present invention are:
[0045] The present invention achieves drug administration by atomizing the drug and bringing the atomized drug into the Eustachian tube through compressed air, or passing through the Eustachian tube into the middle ear.
