Locking Syringe Adapter Connection for Closed Drug Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Healthcare providers are at risk of exposure to hazardous drugs during the reconstitution, transportation, and administration processes due to unintentional drug release into the atmosphere, necessitating a closed system transfer device to prevent exposure.
Innovation Solution
A syringe adapter system with a housing, membrane, needle hub, and connection interfaces that secure and release components using mechanisms like snap-fits, locking collars, and alignment features to ensure a closed transfer of fluids, reducing accidental disconnections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional open transfer methods are used, then ease of operation is improved, but healthcare providers are exposed to hazardous drugs through accidental release into the atmosphere
Solution Approach 1:
The syringe adapter is nested within the vial adapter housing, with the membrane received within the housing interior space. The component housing is received within the syringe adapter housing, creating a nested configuration that maintains closed system integrity while managing complexity through hierarchical integration.
Solution Approach 2:
The connection interface is divided into separate first and second connection interfaces positioned at different locations. The first connection interface engages the component housing while the second connection interface engages the membrane, segmenting the connection function to ensure reliable closed transfer while allowing modular assembly.
2Reliability
If additional clamps or securing mechanisms are added to prevent accidental disconnection, then connection reliability is improved, but device complexity and material costs increase
Solution Approach 1:
The locking collar integrates multiple functions into a single component: it provides mechanical locking engagement, maintains sealing pressure on the membrane, and prevents accidental disconnection. This merging of functions reduces the total number of components needed while maintaining high connection security.
Solution Approach 2:
The locking collar is designed to be movable between locked and unlocked positions, allowing dynamic control of the connection state. This dynamic mechanism enables secure locking during use while allowing easy release when needed, eliminating the need for additional fixed clamps or securing mechanisms.

AI summary
A system for closed transfer of fluids includes a syringe adapter having a housing, a membrane at least partially received within an interior space of the housing, a needle hub positioned, a needle connected to the needle hub, a first connection interface defined by a portion of the housing, a connection release member moveable relative to the housing between a first position and a second position, and a secondary component including a component housing, a component membrane at least partially received within a passageway of the component housing, and a second connection interface positioned on the component housing. The second connection interface is configured to engage the first connection interface. The connection release member is configured to engage the second connection interface and release the second connection interface from the first connection interface when the connection release member is moved to the second position.
