Integrated Flow Stop Assembly for Infusion Pumps
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing flow stop assemblies for portable infusion pumps, which consist of multiple components, complicate manufacturing and increase costs due to the need for assembly, making it difficult to reduce the number of components and improve production efficiency.
Innovation Solution
A flow stop assembly with a tube receiving portion and a tube pressing portion coupled via a hinge, allowing rotational displacement, which reduces the number of components by integrating functions such as blocking and releasing mechanisms into a single member, thereby simplifying assembly and reducing manufacturing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the flow stop assembly consists of multiple components (flow stop blocking arch and flow stop arm), then the blocking function is achieved, but the manufacturing cost increases and production efficiency decreases due to assembly requirements
Solution Approach 1:
The patent integrates the flow stop blocking arch and flow stop arm into a single integrated flow stop assembly. This merging of previously separate components eliminates the need for assembly operations, thereby improving production efficiency while maintaining the blocking function through the unified structure's ability to clamp the infusion tube
2Reliability
If the flow stop assembly consists of multiple components, then the blocking function is achieved, but the manufacturing cost increases due to multiple components requiring assembly
Solution Approach 1:
The patent combines multiple components (flow stop blocking arch and flow stop arm) into a single integrated flow stop assembly. This reduces manufacturing cost by eliminating assembly operations and associated labor, while the integrated structure maintains the blocking function through its unified clamping mechanism
3Reliability
If the flow stop assembly consists of multiple components, then the blocking function is achieved, but assembly errors increase and assembly complexity increases
Solution Approach 1:
The patent integrates multiple components into a single flow stop assembly, thereby eliminating assembly steps and reducing assembly complexity. The unified structure prevents assembly errors while maintaining the blocking function through its integrated clamping design

AI summary
A flow stop assembly is attachable to an infusion pump and includes: a tube receiving portion comprising a fixing portion configured to be fixed to the infusion pump; and a tube pressing portion coupled to the tube receiving portion via a hinge and rotationally displaceable with respect to the tube receiving portion around a rotation axis. The fixing portion is fixable to the infusion pump in a state in which an infusion tube is inserted between the tube receiving portion and the tube pressing portion.
