Medical Tube Clamp Guide Structure for Complete Closure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing medical tube clamps often fail to reliably close the flow path due to lateral misalignment of the presser with the sidewall, leading to incomplete closure, especially in high-pressure or busy medical settings where operations are performed quickly without visual confirmation.
Innovation Solution
A clamp design featuring a guide structure, such as a spherical surface or inclined surfaces, that ensures the presser is guided between the sidewalls, even when laterally misaligned, to ensure complete closure of the medical tube.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the clamp structure is simplified without sidewalls, then ease of operation is improved, but the medical tube may shift laterally causing incomplete closure
Solution Approach 1:
The guide structure acts as an intermediary mechanism that provides lateral guidance without requiring complex sidewall structures. The guide groove and guide surface work together to automatically center the presser during operation, ensuring reliable closure while maintaining simple clamp geometry and fast operation

AI summary
A clamp includes a fixed portion on which a medical tube is placed, a movable portion that is provided above the fixed portion to face the fixed portion, and a closing portion that presses and closes the medical tube when the movable portion is pressed toward the fixed portion. The closing portion includes a presser that protrudes from the movable portion toward the fixed portion and presses the medical tube, a pair of sidewalls that extends, like a wall, from both sides of the fixed portion and prevents the medical tube from being shifted laterally, and a guide structure that allows the presser to be guided between the sidewalls.
