Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing infusion bag pressing devices are prone to excessive expansion or distortion, making them inefficient for rapid and complete discharge of infusion solutions, and are costly due to complex structures.
Innovation Solution
An infusion bag pressing device with an air storage space and a pressing bag that includes unit space portions separated by an interval maintaining member, which is coupled to the pressing bag to prevent excessive expansion, allowing for controlled and efficient discharge of infusion solutions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the pressing bag is expanded by air flowing into the air storage space, then the infusion bag can be pressed to discharge the infusion solution, but the pressing bag may be excessively expanded or distorted
Solution Approach 1:
The air storage space is divided into multiple unit space portions by interval maintaining members. These members segment the single large air storage space into several smaller units, preventing the pressing bag from excessive expansion or distortion while still enabling effective pressing action on the infusion bag.
Solution Approach 2:
Interval maintaining members are introduced as intermediary elements within the air storage space. These members act as mediators that control the expansion behavior of the pressing bag, preventing direct excessive contact between the expanding air and the pressing bag walls, thereby maintaining shape stability.
2Productivity
If a piston-type or syringe-type medicine injection device is used to inject large amount of medicine emergently, then the injection speed can be increased, but the device structure becomes complicated and manufacturing cost increases
Solution Approach 1:
The complex piston or syringe mechanisms are extracted and replaced with a simple air-filled pressing bag system. The invention takes out the complicated mechanical injection components and substitutes them with a simpler pneumatic pressing mechanism that achieves the same emergency injection function.
Solution Approach 2:
The pressing bag system uses simple, inexpensive materials compared to piston-type or syringe-type devices. The air storage space and pressing bag can be designed as disposable or single-use components, significantly reducing manufacturing costs while maintaining the ability to inject large amounts of medicine emergently.
