Fluid Transfer Coupling for Dual Syringe Compatibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing medicine bottle syringe adapters lack child-resistant features and often compromise them when used with child-resistant medication bottle caps, and they typically only accommodate one type of syringe connection, failing to accommodate the two prevalent syringe styles: male oral slip tip and ISO 80369-3 compliant syringes.
Innovation Solution
The development of fluid transfer couplings with dual connection capabilities, featuring a cylindrical body with hinged shelves and flanges that allow for secure engagement with both male oral slip tip and ISO 80369-3 compliant syringes, maintaining child-resistant functionality while enabling fluid transfer from medication bottles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single-type syringe adapter is used, then the device complexity is reduced, but the adaptability to different syringe types deteriorates
Solution Approach 1:
The adapter incorporates both a female port for male-oriented oral slip tip syringes and a male port for ISO 80369-3 compliant female tip syringes within a single device, enabling one adapter to serve multiple syringe connection types without increasing overall structural complexity
2Ease of operation
If an adapter is added to facilitate syringe connection, then the ease of operation is improved, but the child-resistant functionality deteriorates
Solution Approach 1:
The adapter integrates the syringe connection port directly into the child-resistant cap assembly, merging the child-protection function with the fluid transfer function in a single integrated component rather than using separate adapter and cap devices
