Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing medical connectors for fluid transfer between containers expose nursing personnel to hazardous medicaments due to potential disconnection and leakage, as they lack secure locking mechanisms, especially during the transfer process.
Innovation Solution
A female piercing member protection device with a deformable locking mechanism and a second locking device, allowing for secure connection and prevention of accidental disconnection, ensuring the needle is never exposed, and enabling safe drug administration by locking the fluid container in place after connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a simple connector design is used for fluid transfer, then the device complexity is reduced, but the reliability of preventing accidental disconnection deteriorates
Solution Approach 1:
The connector employs a dynamic locking mechanism where the outer casing can be moved between a first position (where the connection member is locked) and a second position (where the connection member can move along the longitudinal axis). This dynamic positioning system allows the connector to transition between locked and unlocked states, providing reliable prevention of accidental disconnection while maintaining manageable device complexity through controlled movement rather than complex multi-component assemblies.
2Reliability
If a deformable locking device is used to prevent disengagement, then the reliability of connection is improved, but the device complexity increases
Solution Approach 1:
The locking mechanism utilizes parameter changes in the deformable locking device, which can change its deformation state based on the position of the outer casing. When the outer casing is in the second position, the locking device is prevented from deformation by the outer casing, securing the male connection part. This approach achieves high connection security through material property utilization rather than complex mechanical structures.
3Ease of operation
If the connection member is always exposed for easy access, then the ease of operation is improved, but the harmful factors exposure to personnel increases
Solution Approach 1:
The connector design implements preliminary protection by default, where the connection member is locked in the first position during storage and transport, preventing exposure to hazardous medicaments. The user must intentionally move the outer casing to the second position to access the connection member for fluid transfer. This preliminary protective action ensures safety without compromising operational ease, as the unlocking process is simplified through the movable outer casing design.
