The gas flowmeter 212 is an existing structure, and the model can be set as AFM0725. The gas flowmeter 212 and the air pump 213 are both electrically connected to an existing controller. The preset value of gas output can be set from the controller. By controlling the air pump 213 to work, gas can be output. The gas flowmeter 212 is used to monitor the gas output volume. After reaching the preset value, the controller controls the air pump 213 to pause working, so as to quantitatively transport gas into the inner cavity of the movable frame 21. The quantitatively input gas will push the push plate 27 upward, displacing a quantitative amount of anesthetic in the inner cavity of the liquid storage chamber 1, which is convenient for the use of medical staff. The rubber frame 25 is used to seal the connection between the movable frame 21 and the liquid storage chamber 1.

[0024] As an implementation manner in this embodiment, as Figures 1 - 6 shown, a connecting bar 22 is fixedly installed on the side surface of the movable frame 21. A connecting frame member 23 is movably sleeved on the outer wall of the connecting bar 22. The connecting frame member 23 is fixedly installed on the side surface of the liquid storage bin 1. The top of the connecting bar 22 is rotatably connected to a limiting block 24. The bottom of the limiting block 24 is movably connected to the top of the connecting frame member 23. The inserting block 272 can be inserted into the square groove 261, and the magnetic attracting block 262 can magnetically attract the inserting block 272, realizing the function of temporarily positioning the whole pushing plate 27 at the top of the movable frame 21. The rubber sleeve 271 can make the whole pushing plate 27 be hermetically connected to the inner wall of the liquid storage bin 1. Through the design of the connecting bar 22, the connecting frame member 23 and the limiting block 24, the movable frame 21 is detachably connected to the bottom of the liquid storage bin 1.

[0025] As an implementation manner in this embodiment, as Figure 1 , Figure 2 shown, a support plate 26 is fixedly installed on the inner wall of the movable frame 21. A square groove 261 is opened at the top of the support plate 26. A magnetic attracting block 262 is fixedly installed at the bottom of the inner wall of the square groove 261. An inserting block 272 is movably inserted into the inner cavity of the square groove 261. The inserting block 272 is fixedly installed at the bottom of the pushing plate 27. The bottom of the inserting block 272 is magnetically connected to the top of the magnetic attracting block 262. A threaded cover 12 is threadedly connected to the top of the top plate 11.

One end of the extension pipe 14 away from the internal threaded cylinder 13 is fixedly connected to an atomizing nozzle 15. By moving the extension pipe 14, the atomizing nozzle 15 is aligned with the patient's throat. Then, the air pump 213 is controlled to work, so that the anesthetic is sprayed out in a mist form from the atomizing nozzle 15, realizing the anesthetic function. The extension pipe 14 and the atomizing nozzle 15 are disposable structures. Through the design of the connection relationship between the internal threaded cylinder 13 and the extension pipe 14, the used extension pipe 14 and atomizing nozzle 15 can be disassembled and discarded. By opening the threaded cover 12, the anesthetic can be added into the inner cavity of the liquid storage bin 1.

[0026] Working principle: When in use, the anesthetic is added into the liquid storage bin 1 by opening the threaded cover 12. Then, the extension pipe 14 is moved to align the atomizing nozzle 15 with the patient's throat. Then, the air pump 213 is controlled to work, and gas is conveyed into the movable frame 21. The whole pushing plate 27 is pushed upward in the inner cavity of the liquid storage bin 1 by the gas, so that the anesthetic is sprayed out in a mist form from the atomizing nozzle 15, realizing the anesthetic function. After use, the limiting block 24 is rotated to a position overlapping with the connecting bar 22, and then the movable frame 21 is separated from the bottom of the liquid storage bin 1. Then, the pushing plate 27 is disassembled from the inner cavity of the liquid storage bin 1, facilitating the work of thorough cleaning.
