Lamprey Lock Connector With O-Ring-Sealed Large Inner Diameter
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connections between catheters and tubing have smaller diameters than the catheters themselves, leading to restricted fluid flow and potential leaks.
Innovation Solution
The lamprey lock device features a tubular housing with a lumen, an O-ring, and a luer taper adapter with a threaded internal surface, allowing for a larger inner diameter connection that maintains a secure seal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If standard luer lock connection is used, then connection security is improved, but fluid flow rate deteriorates due to smaller diameter
Solution Approach 1:
The connector is divided into two distinct parts: a luer taper adapter that maintains compatibility with standard luer lock connections, and a lamprey lock receptacle that provides a larger diameter connection. This segmentation allows each part to optimize for its specific function while working together as a unified system.
Solution Approach 2:
The luer taper adapter serves as an intermediary component that bridges between the standard luer lock connection and the larger diameter lamprey lock connection. It receives the standard luer connector and transmits fluid to the larger diameter outlet, effectively mediating between two different connection standards.
2Productivity
If larger diameter connection is used, then fluid flow rate is improved, but compatibility with standard catheters deteriorates
Solution Approach 1:
The connector device performs multiple functions: it maintains compatibility with standard luer lock catheters while simultaneously providing a larger diameter connection for improved flow. The luer taper adapter portion universally accepts standard luer connectors, making the device adaptable to existing catheter systems.
Solution Approach 2:
The luer taper adapter is nested within the lamprey lock receptacle housing. The smaller luer adapter fits inside the larger receptacle structure, allowing the standard connection interface to be contained within the larger diameter connection system, much like nested dolls of different sizes.
3Productivity
If larger diameter connection is used, then flow disturbance is reduced, but connection security may deteriorate
Solution Approach 1:
The connector employs composite construction with the luer taper adapter made from one material and the lamprey lock receptacle made from another material. This composite approach allows optimization of each component for its specific requirements while maintaining overall structural integrity and connection security.
