The vial containing mechanism 1 includes a vial receiving slot and a vial fixing device. The vial fixing device includes a clamping part 11, which is an elastic buckle that secures the vial opening by snapping. The elastic buckle can have 3 to 8 snap positions, for example, 3, 4, 5, 6, 7, or 8. There are no special requirements on the number of snap positions, allowing for easy disassembly and replacement of the vial. The puncture device 2 includes a valve body housing 21 and a puncture needle 22; the puncture needle 22 is fixed to the valve body housing 21. One end of the drug delivery line 3 is connected to the puncture needle 22 through the valve body housing. The volume of vial 13 can be 1 to 20 mL, such as 2 mL, 3 mL, 5 mL, 10 mL, 15 mL or 20 mL. There are no special requirements for the volume of vial 13, as long as it can be used in conjunction with vial containing mechanism 1 and vial fixing device.
[0032] In one specific embodiment, the valve body housing 21 has a raised profile 23. In use, after the puncture needle 22 penetrates the vial stopper 12, the guide slope 25 of the valve body housing 21 is more conducive to the valve body housing passing through the vial stopper 12. The raised profile 23 of the valve body housing 21 will form a channel for gas exchange at the vial stopper 12. At the same time, the slope 24 of the valve body housing 21 blocks the leakage of the medicine. Since the pressure inside and outside the vial is balanced, the backflow of the medicine can be prevented.

There are no restrictions on the gas line; it can be a straight or curved stainless steel needle. There are no special requirements for the inner diameter or material of the gas line, as long as it can quickly penetrate the vial stopper without producing any debris.
[0034] In one specific embodiment, the liquid delivery pipeline 3 is made of plastic, but it can also be made of other materials without limitation, so as to ensure the stability of the liquid and prevent the quality of the liquid from being affected by mutual reactions, adsorption or swelling during use.
[0035] In one specific embodiment, the puncture needle 22 is made of stainless steel, such as 316L stainless steel; the inner diameter of the puncture needle is 0.5-2.0 mm. There are no special requirements for the material and inner diameter of the puncture needle, with the aim of quickly penetrating the rubber stopper of the vial without producing rubber stopper debris or reacting with the drug solution or causing swelling.
[0036] In one specific embodiment, the other end of the liquid delivery pipeline 3 can be connected to an atomizing mechanism to deliver the liquid medicine to the atomizing mechanism. The other end of the liquid delivery pipeline 3 can also be connected to a power device. The other end of the delivery pipeline 3 can also be connected to both the atomizing mechanism and the power device simultaneously. For example, a three-way pipeline can be set up. This is a conventional design for those skilled in the art, and this patent application will not elaborate further. In addition, the atomizing mechanism and the power device can adopt conventional designs for those skilled in the art. This application does not impose any restrictions and can be selected according to actual needs to achieve the purpose of liquid collection and atomization.
