Vial Adaptor With Deflectable Tabs For Universal Fit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vial adaptors face challenges in accommodating a wide range of vial sizes and configurations, leading to inefficiencies in medication extraction and potential exposure to harmful substances.
Innovation Solution
The development of a vial adaptor with a body portion, penetrating portion, and interface portion, featuring deflectable tabs and axial openings, which allows for secure attachment and efficient fluid extraction across various vial sizes by minimizing the distance between the penetrating portion and the fluid barrier surface, while providing shielding and easy removal mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single vial adaptor design is used, then device simplicity is maintained, but it cannot effectively accommodate a wide range of vial sizes and configurations
Solution Approach 1:
The adaptor incorporates deflectable tabs that can dynamically adjust their position and shape to accommodate different vial sizes and configurations. These tabs are designed to flex and adapt during the attachment process, allowing the same adaptor design to work with multiple vial types without requiring complex interchangeable components.
Solution Approach 2:
The adaptor design utilizes parameter changes in the deflectable tabs' physical state (from undeflected to deflected positions) to achieve adaptability. By changing the geometric parameters of the tabs through controlled deflection, the adaptor can adjust its dimensions to fit various vial opening sizes while maintaining a single unified design.
2Productivity
If the penetrating portion is positioned closer to the fluid barrier surface, then medication extraction efficiency is maximized, but the risk of exposure to harmful substances increases
Solution Approach 1:
The interface portion serves as an intermediary element between the penetrating portion and the external environment. It provides a shielding barrier that protects the user from harmful substances while allowing the penetrating portion to be positioned optimally close to the fluid barrier surface for efficient medication extraction. The interface portion acts as a protective mediator that enables close positioning without direct exposure.
3Ease of operation
If deflectable tabs are used for secure attachment, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The deflectable tabs are designed to perform self-service during the attachment process. As the adaptor is pushed onto the vial, the tabs automatically deflect outward and then spring back to engage with the vial's rim, securing the attachment without requiring manual manipulation or additional components. This self-actuating mechanism improves ease of operation while adding minimal structural complexity.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The vial adaptor effectively supports a wide range of vial sizes, maximizes medication extraction, and reduces exposure to harmful substances through secure attachment and efficient fluid flow, ensuring safe and efficient use in medical settings.
Implementation Method 1
at least one deflectable tab comprising a proximal end, a distal end, and a protruding portion, the proximal end being supported by the body portion and the distal end being unrestrained so as to allow at least the distal end of the tab to be deflectable away from the penetrating portion

AI summary
A vial adaptor configured to be attached to a wide range of vial sizes, the adaptor being configured to penetrate the vial seal so that the contents of a vial can be removed. The vial adaptor can have a body portion, a penetrating portion projecting from the body portion and configured to be inserted through the seal and positioned within an interior space of the vial so that the contents of the vial can flow through an opening in the penetrating portion, an interface portion supported by the body portion that is connectable to a syringe or other medical implement, at least one deflectable tab configured be bendable by hand or to bend in response to contact with the vial. The vial can also have a filtered air vent to allow air to fill the vial as the contents thereof are being removed.
