Vial Stabilizer Base with Universal Adapter
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Healthcare providers face risks of exposure to hazardous chemotherapy drugs during reconstitution, transportation, and administration due to unintentional release of drugs into the atmosphere during transfer, as existing systems fail to effectively manage differential pressures within vials.
Innovation Solution
A vial stabilizer base with a vial adapter system that securely attaches to vials of different sizes, using elastically deformable arms and retaining tabs to create a snap fit mechanism, allowing for closed system transfer while preventing drug exposure through pressure equalization and secure attachment to a closed system transfer device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a closed system transfer device is designed to attach to a specific vial size, then the attachment reliability is improved, but the adaptability to different vial sizes deteriorates
Solution Approach 1:
The vial adapter is designed as a universal interface component that can accommodate multiple vial sizes (e.g., 13mm and 20mm vials) while maintaining secure attachment to the closed system transfer device. The adapter includes a body with an opening configured to receive different vial types and attachment features that engage with the transfer device, enabling one transfer device to work with multiple vial sizes through the standardized adapter interface
2Reliability
If the vial adapter is designed to securely attach to the transfer device, then the attachment reliability is improved, but the device complexity increases
Solution Approach 1:
The system is segmented into distinct functional components: the vial adapter body, the attachment features, and the interface elements. This segmentation allows each component to be optimized independently - the body provides structural support and vial reception, while the attachment features provide secure connection to the transfer device, reducing overall complexity through modular design
Solution Approach 2:
The vial adapter incorporates nested structural elements where the attachment features are integrated into the body structure. The opening for receiving the vial is formed within the body, and the attachment features are positioned within or on the body structure, creating a compact nested design that reduces complexity compared to separate components

AI summary
A system includes a vial stabilizer base having a first body and a plurality of fingers projecting from the first body, with the plurality of fingers being annularly disposed about the first body, and a vial adapter having a second body and a plurality of arms projecting from the second body. The second body defines a passageway. The plurality of fingers of the vial stabilizer base defines a socket having a first seat configured to receive a vial and a second seat configured to receive the vial adapter.
