The present invention belongs to the field of medical atomization equipment, and particularly relates to a portable combined inhalation device suitable for vials.
Ampoules are widely used as inner packaging materials for sterile liquid preparations due to the characteristics of low cost, uniform material, high-temperature sterilization resistance, and the like. However, the ampoules are inconvenient for clinical use and pose a safety risk. For example, particles such as glass scraps and the like in the production process environment are easily inhaled through the instantaneous negative pressure at the ampoule filling and sealing bottleneck. There is a high risk for pathogenic bacteria in the hospital environment to be inhaled through the instantaneous negative pressure during use, causing contamination. Although plastic ampoules can reduce contamination in the production process to a certain extent, it is difficult to avoid environmental contamination during use. Therefore, in developed countries such as Europe and the United States, the trend of using vials instead of ampoules has become more and more significant in recent years.
Chinese patent CN111840715A discloses a combined portable inhalation device comprising a disposable dedicated bottle for an atomized medicament, which requires the use of the disposable dedicated bottle for the atomized medicament specified in the patent, and requires an additional production line for the disposable dedicated bottle for the atomized medicament, such that the cost is high; if other non-dedicated bottles are used to package medicinal liquid, the medicinal liquid needs to be taken out and then put into the disposable dedicated bottle for the atomized medicament for use, and the poor use environment or improper operations will lead to a high probability of cross-contamination.

The support 10 can be adapted according to the lids of vials 3 with different sizes to meet different requirements.
The puncture device 11 is arranged in the accommodating groove 101 of the support 10 and extends upwards from the middle portion of the bottom surface of the support 10, and the height of the puncture device 11 protruding upwards does not exceed a top end of the side wall of the support 10; an upper-end portion of the puncture device 11 forms a sharp end, which can puncture a rubber stopper of a lid of the vial 3; the puncture device 11 is provided with a gas channel 112 and a liquid channel 111; when the vial 3 is mounted on the support 10 in an opening direction, the puncture device 11 punctures the rubber stopper of the vial lid and enters the vial 3, and medicinal liquid in the vial 3 flows from the liquid channel 111 of the puncture device 11 into the atomizing device 2.
In this example, the length of the puncture device 11 extending upwards is 6 mm, and the length of the puncture device 11 puncturing and entering the vial 3 will affect the outflow or complete outflow of the medicinal liquid, and thus it is not preferable to be too long, nor too short.

Firstly, the connecting device can be adapted to vials 3 with various standard sizes without opening additional mold and non-standard filling lines, so that the production cost of the medicament is controlled; the puncture device 11 of the connecting device 1 punctures the vial 3, to avoid the waste and contamination of the medicinal liquid caused by transferring the medicinal liquid to the dedicated bottle of the atomizing device 2, and the medicinal liquid can be rapidly atomized by flowing to the atomizing sheet 212.
Secondly, the manner that a plurality of parts are detachably assembled is adopted, such that the atomizing sheet 212 assembly and the main unit 22 can be cleaned and disinfected conveniently and can be reused many times, and moreover, the probability of cross-contamination or infection of medicinal liquids caused by the atomization of different medicaments can be reduced.
In addition, in each of the aforementioned examples, after the atomization, inhalation, and administration are finished, the connecting device 1 is rotated and unscrewed from the atomizing main unit 22, taken out, and then classified and recycled as medical waste; meanwhile, a snap-fitting button on the main unit 22 is pressed, and the atomizing body 21 or the atomizing sheet assembly 23 is taken down; after soaking in high-temperature boiled water for 2 min, the atomizing body or the atomizing sheet assembly are wiped dry with medicinal cotton, put into a sterile plastic bag, and stored for later use; alternatively, after a disinfectant is added to the screw groove to disinfect the atomizing sheet 212 and the inner wall of the screw groove, the outer surface of each part of the device is cleaned and disinfected, and then these parts are independently packaged, sealed, and stored for later use. The present invention has been described in detail above, but the present invention is not limited to the aforementioned examples. All equivalent changes and modifications made according to the spirit of the present invention should fall within the protection scope of the present invention.
