Slip Luer Connector With Actuated Latch Member
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current luer connectors face issues with disconnection and leakage under strong forces or bending, requiring more time and force to switch between interlocking tubes, which complicates applications like surgical procedures.
Innovation Solution
A luer assembly comprising a hub member and a latch member with a blade that can be actuated between positions to securely lock a male slip luer within a female luer connector, providing a secure and leak-free connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If luer threads are used to secure the male and female tubes together, then the connection security is improved, but the time required to switch between interlocking tubes increases and more force is required to tighten and loosen tubes
Solution Approach 1:
The connector is divided into two functional parts: a slip luer mechanism for quick insertion and a separate latch member for secure locking. This segmentation allows the connector to achieve both quick connection (like slip luer) and secure locking (like threaded) without the drawbacks of either alone, resolving the contradiction between connection security and switching time
Solution Approach 2:
The latch member is pre-positioned to automatically engage with the hub member upon insertion of the male luer. This preliminary positioning ensures that the secure locking action occurs automatically during the insertion process itself, eliminating the need for additional tightening actions and maintaining quick switching capability while ensuring connection security
2Reliability
If luer threads are used to secure the male and female tubes together, then the connection security is improved, but the force required to tighten and loosen tubes increases
Solution Approach 1:
The connector separates the insertion function (slip luer) from the locking function (latch member), eliminating the need for high-force threading actions. The latch member provides secure locking through a simple engagement mechanism that requires minimal force to activate and deactivate
Solution Approach 2:
The latch member is designed to automatically engage and lock the male luer in place through its own elastic deformation and blade engagement with the hub member. This self-locking mechanism eliminates the need for additional force to maintain the connection, while still providing secure locking that resists disconnection under load
3Loss of time
If a simple slip luer connector is used, then the switching time is reduced, but the connection security deteriorates under strong force or bending
Solution Approach 1:
The invention merges the quick-connection advantage of slip luer connectors with the secure-locking advantage of threaded connectors into a single hybrid device. The slip luer portion enables fast insertion, while the integrated latch member provides automatic secure locking, achieving both quick switching and high connection security simultaneously
Solution Approach 2:
The latch member is designed with elastic properties that allow it to dynamically adapt during insertion, automatically engaging and locking the male luer. This dynamic engagement provides secure locking that actively resists disconnection forces and bending, while maintaining the quick insertion capability of slip luer connectors

AI summary
A slip luer assembly includes a hub member and a latch member coupled to the hub member. The hub member includes an outer hub surface, an inner hub surface and a window surface. The window surface defines a window extending from the outer hub surface to the inner hub surface. The latch member includes at least one blade. The latch member is configured to be actuated between a first position and a second position. In the first position, the at least one blade is not positioned within the window of the hub member. In the second position, the at least one blade is positioned at least partially within the window of the hub member.
