Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current fluid transfer systems between containers and syringes lack efficient and accurate dispensation methods, particularly for medications stored in larger volumes, as they often result in dosing inaccuracies and inadequate sealing, leading to inefficiencies in fluid transfer and storage.
Innovation Solution
A capping device or bottle adapter with a male ENFIT compatible coupling and a sealing mechanism, including a resilient grommet, that facilitates secure engagement with syringes and containers, ensuring accurate fluid transfer and preventing leakage, while accommodating different bottle sizes through adjustable flanges and a flexible design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional transfer lids or press-in adapters are used, then fluid transfer between containers and syringes is enabled, but dosing inaccuracies occur and sealing is inadequate
Solution Approach 1:
The patent introduces an intermediary adapter device that couples between the container and syringe. This adapter includes a container coupling portion that interfaces with the container opening and a syringe coupling portion that interfaces with the syringe hub, creating a controlled fluid transfer pathway that ensures both accurate dosing and reliable sealing
Solution Approach 2:
The adapter is divided into distinct functional segments: a container coupling portion with external threads for engaging the container, a syringe coupling portion with internal threading for the syringe hub, and a body portion connecting these elements. This segmentation allows each portion to be optimized for its specific function while working together as an integrated system
2Adaptability or versatility
If a fixed design adapter is used, then manufacturing is simplified, but adaptability to different bottle sizes is limited
Solution Approach 1:
The adapter incorporates a flexible diaphragm or membrane in its body portion that can deform elastically to accommodate variations in container opening sizes and shapes. This dynamic flexibility allows the same adapter design to adapt to different bottle configurations without requiring multiple specialized adapters
Solution Approach 2:
The adapter is designed with universal coupling mechanisms that can interface with various container types and syringe models. The external threads on the container coupling portion and the internal threading on the syringe coupling portion are designed to accommodate standard variations, making the adapter broadly compatible across different product lines
