Catheter Valve Holder Structure to Prevent Line Kinking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Catheter drainage lines are prone to jostling, twisting, or kinking during handling, causing user discomfort.
Innovation Solution
A catheter stabilization device with a base and upwardly extending arms that securely hold the catheter valve or sample port, featuring narrower inlet and outlet openings to prevent movement, and optionally elastic arms for retention and adhesive attachment for stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the catheter drainage line is left loose and movable for ease of handling, then the ease of operation is improved, but the catheter becomes prone to jostling, twisting, or kinking which causes user discomfort
Solution Approach 1:
The patent introduces a stabilization device as an intermediary component between the catheter drainage line and the user's body. This device includes a base with adhesive material for attachment to the user's leg, arms that extend upward to support the catheter, and a valve holder that secures the catheter valve. The stabilization device acts as a mediator that prevents the drainage line from moving excessively while still allowing necessary access and manipulation, thereby eliminating the harmful jostling, twisting, or kinking that causes user discomfort.
2Stability of the object's composition
If the catheter valve is securely held in place to prevent movement, then the stability of the catheter is improved, but the ease of accessing the valve for opening or closing becomes more difficult
Solution Approach 1:
The valve holder is designed with elastic arms that provide a dynamic holding mechanism. The elastic material allows the arms to flex and yield when force is applied to access the valve, while maintaining secure holding during normal conditions. This dynamic property enables the valve to be easily accessed when needed while remaining stable during routine use.
Solution Approach 2:
The patent employs elastic arms made of flexible material to construct the valve holder. These flexible arms can be compressed or expanded to allow access to the valve while maintaining a secure holding force. The flexibility of the arms enables easy valve manipulation while preserving catheter stability during normal operation.
3Ease of operation
If the drainage line is allowed to move freely for easy manipulation, then the ease of operation is improved, but the drainage line becomes prone to twisting or kinking which reduces drainage efficiency
Solution Approach 1:
The stabilization device serves as an intermediary support structure that prevents the drainage line from twisting or kinking while still allowing necessary manipulation. The base attaches to the user's leg, and the arms extend upward to support the catheter at an optimal angle, creating a stable configuration that maintains drainage efficiency while permitting access when needed.

AI summary
A catheter stabilization device of a catheter stabilization system includes a base having a top surface and a bottom surface, a first arm having a first inner surface and a second arm having a second inner surface, the first arm and the second arm each extending upwardly from the top surface of the base, the first inner surface and the second inner surface defining between them a space for receiving a valve or sample port for a catheter, the valve or sample port including inlet and outlet components and an enlarged portion between the inlet and outlet components, the first inner surface and the second inner surface further defining between them inlet and outlet openings at ends of the space for the inlet and outlet components of the valve or sample port, the inlet and outlet openings being narrower than a widest portion of the space.
