Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions for connecting syringes to vials in medical contexts lack effective control over fluid flow, leading to issues with reconstitution and administration, such as leakage and incomplete mixing.
Innovation Solution
A vial adaptor with a syringe connection port, a vial connection port, and a conduit, featuring a valve that selectively blocks and allows fluid flow between the syringe and vial, enabling controlled dispensing and reconstitution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a simple connection device is used to connect syringe to vial, then the device complexity is reduced, but fluid flow control is lost leading to leakage and incomplete mixing
Solution Approach 1:
A valve mechanism is introduced as an intermediary component within the connection device. The valve selectively blocks and allows fluid flow between the syringe and vial, providing reliable control over the reconstitution process while preventing leakage and ensuring complete mixing.
2Ease of operation
If manual operation is used for fluid transfer, then ease of operation is improved, but productivity decreases due to time-consuming reconstitution
Solution Approach 1:
The valve mechanism enables dynamic control of fluid flow, allowing the user to quickly switch between blocked and allowed states. This dynamic capability accelerates the reconstitution process by enabling rapid fluid transfer while maintaining ease of manual operation through simple valve actuation.
3Manufacturing precision
If the valve fluid passageway diameter is made smaller, then manufacturing precision is improved, but fluid flow rate decreases
Solution Approach 1:
The valve passageway diameter is optimized to a specific range that balances manufacturing precision with adequate fluid flow rate. The passageway is configured with dimensions that can be precisely manufactured while maintaining sufficient flow capacity for efficient reconstitution, resolving the contradiction between precision and productivity.
