Infusion Flow Regulator with Single-Plane Arc and Circular Paths
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing infusion flow regulators face challenges in manufacturing accuracy, ease of use, and stability during flow rate regulation due to complex structures and separate rubber packing for arc-shaped and discharge guide grooves, leading to potential inaccuracies and inconvenience in handling.
Innovation Solution
A simplified design with a single flat surface for both arc-shaped and circular flow paths, a connecting flow path, and a single sealing member to cover all flow paths, allowing for easy assembly and precise regulation, along with a handle for stable grip and rotation, ensuring accurate flow rate control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the arc-shaped flow path and discharge guide groove are formed at different installation surfaces with separate rubber packing, then the flow rate can be regulated by rotation, but the structure becomes complex and manufacturing precision deteriorates
Solution Approach 1:
The patent merges the arc-shaped flow path and discharge guide groove onto the same installation surface, eliminating the need for separate rubber packing and complex multi-surface alignment. This consolidation simplifies the overall structure while maintaining the flow rate regulation function through rotational adjustment of the flow regulator body.
2Manufacturing precision
If the arc-shaped flow path and discharge guide groove are formed at different installation surfaces, then flow rate can be regulated, but manufacturing precision and assembly accuracy become difficult to maintain
Solution Approach 1:
By combining both flow path features on a single installation surface, the patent eliminates complex multi-surface alignment requirements during assembly. This reduces manufacturing difficulty and improves assembly accuracy, as only a single sealing surface needs to be precisely manufactured and assembled.
3Ease of operation
If the body is held with one hand and the first body is rotated with the other hand, then flow rate can be adjusted, but stable handling becomes difficult and the tube may move
Solution Approach 1:
The patent incorporates a finger rest that allows the user's finger to rest on the body while operating the flow regulator. This self-service feature provides inherent stability during operation, enabling the tube to remain stable while the flow rate is being adjusted through rotation of the first body.

AI summary
The present invention relates to an infusion flow adjuster which is used in order to adjust the flow rate of an infusion solution to be administered when performing infusion therapy, and relates to an infusion flow adjuster in which an arc-shaped flow path for adjusting the distance through which the infusion solution passes and a circular flow path for inducing discharge of the infusion solution that has passed through the arc-shaped flow path are constituted in a single plane, and which is easy to produce as a product for accurately adjusting the flow rate, affords convenience of handling being provided with a handle in a suitable position, and also, in addition to allowing fine adjustment of the flow rate, limits the maximum flow rate to an appropriate value, so being convenient to use during actual infusion therapy.
