Innovation Solution
A portable combined inhalation device designed for vials, featuring a connecting device with a puncture mechanism that allows direct connection to vials, ensuring balanced pressure and preventing contamination, using inert materials and sterile packaging to maintain medicinal liquid quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If ampoules are used for packaging medicinal liquid, then the cost is low and sterilization resistance is high, but particles and pathogenic bacteria can be inhaled through instantaneous negative pressure causing contamination
Solution Approach 1:
The device separates the packaging function (vial with rubber stopper) from the atomization function (atomizing device), allowing the vial to maintain its sealing integrity while the atomizing device provides controlled access through a puncture mechanism, eliminating the harmful negative pressure effect of traditional ampoules
Solution Approach 2:
The rubber stopper acts as an intermediary between the sealed vial and the atomizing device, allowing controlled puncture and connection while maintaining the sealing integrity of the vial, thus preventing particle and bacterial contamination while enabling safe medication delivery
2Object-affected harmful factors
If disposable dedicated bottles are used for atomized medicament, then contamination is reduced, but additional production lines are required and cost increases
Solution Approach 1:
The connecting device with puncture mechanism is designed to be universally compatible with standard vials, allowing the same device to work with various medicinal liquids packaged in conventional vials, eliminating the need for dedicated expensive bottles while maintaining contamination prevention
Solution Approach 2:
The connecting device is designed as a disposable component that is inexpensive to manufacture, allowing it to be discarded after single use, which prevents cross-contamination without requiring expensive reusable dedicated bottles or additional production lines
3Object-affected harmful factors
If medicinal liquid is transferred to disposable dedicated bottle, then contamination is reduced, but poor use environment or improper operations lead to high probability of cross-contamination
Solution Approach 1:
The vial is pre-sealed with a rubber stopper and the connecting device is prepared with a sterile puncture mechanism before use, allowing the user to simply connect the devices without complex transfer operations, thus eliminating cross-contamination risks associated with manual liquid handling
4Object-affected harmful factors
If vials are used instead of ampoules, then environmental contamination during use is reduced, but the device structure becomes more complex
Solution Approach 1:
The puncture device is integrated within the connecting device structure, with the puncture needle nested inside a protective sheath that is part of the connecting device housing, allowing the complex functionality to be compactly integrated without significantly increasing overall device complexity

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device allows for convenient and safe atomization of medicinal liquids from vials without transferring them to dedicated bottles, reducing contamination risks and production costs, while maintaining the quality of the medicinal liquid.
Implementation Method 1
the gas channel can enable the pressure in the whole device system to be kept balanced and ensure the smooth flow of the medicinal liquid into the atomizing device
Implementation Method 2
the gas channel can enable the pressure in the whole device system to be kept balanced and ensure the smooth flow of the medicinal liquid into the atomizing device

AI summary
The present invention relates to a portable combined inhalation device suitable for vials, comprising an atomizing device and a connecting device detachably connected to the atomizing device; the connecting device comprises a support on which an accommodating groove capable of accommodating a vial is formed, and a puncture device that is arranged on the support and can puncture a rubber stopper of the vial; the puncture device comprises a liquid channel and a gas channel. If the vial, the connecting device, and the atomizing device are connected, one end of the liquid channel communicates with the vial, and the other end communicates with the atomizing device; one end of the gas channel communicates with the vial, and the other end communicates with air. The present invention can directly introduce medicinal liquid in the vial into the atomizing device for atomization under the action of atmospheric pressure, without the need to first transfer the medicament in the vial to a dedicated atomizing bottle and then connect the dedicated atomizing bottle to the atomizing device, thereby being more convenient and safer to use, and greatly reducing the possibility of the medicinal liquid being contaminated; in addition, the device has a simple structure.
