Pharmaceutical Adaptor Sealing Element for Syringe Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a pharmaceutical adaptor system that ensures correct assembly and safe fluid communication between a glass syringe and other medical devices, such as needles, vials, or catheters, particularly for home administration where users may lack expertise.
Innovation Solution
The pharmaceutical adaptor system includes a syringe assembly with a male tubular projection, a connecting element, and an adaptor with a sealing element that provides a fluid-tight connection. The sealing element absorbs axial tolerances and provides consistent user feedback for correct assembly, ensuring a firm and uniform connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If users assemble pharmaceutical administration systems themselves at home, then the need for ready-to-use systems is reduced and cost is lowered, but the risk of incorrect assembly and fluid leakage increases
Solution Approach 1:
The patent incorporates visual feedback mechanisms (colored rings, alignment indicators) and tactile feedback (click sensations, mechanical stops) that provide immediate confirmation to users when components are correctly assembled. This feedback system ensures that even inexperienced home users can reliably assemble the system correctly, eliminating the trade-off between user assembly and connection reliability.
2Ease of manufacture
If standard Luer couplings are used for fluid transfer, then economical and reliable components are achieved, but home users lack the expertise to use them correctly
Solution Approach 1:
The system is designed to be self-guiding and self-verifying through integrated visual and tactile indicators. The alignment markers and color-coded components guide users through the assembly process automatically, while mechanical stops and click sensations confirm correct positioning. This self-service approach eliminates the need for user expertise while maintaining ease of operation.
3Measurement precision
If glass syringes are used for fluid administration, then precise dosing is achieved, but ensuring fluid tight connections during transfer becomes problematic
Solution Approach 1:
The adaptor system serves as an intermediary component between the glass syringe and the administration device. It features a sealing element that interfaces with the syringe's male tubular projection, creating a reliable fluid-tight connection while preserving the precision dosing capabilities of the glass syringe. The adaptor absorbs axial tolerances and provides mechanical stabilization.
4Ease of operation
If users handle and assemble pharmaceutical systems at home, then professional assistance is reduced, but the risk of medicine loss and incorrect dosing increases
Solution Approach 1:
The system incorporates preliminary alignment features and pre-configured sealing mechanisms that guide users through correct assembly before fluid transfer begins. The visual indicators and mechanical guides ensure proper positioning of components, preventing incorrect assembly that could lead to medicine loss or dosing errors. The sealing element is pre-positioned to engage with the syringe projection.
