Syringe Blinding Carton with Nested Housing and Flange Securing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for blinding clinical trials, such as opaque vials and makeshift syringe covers, are inconvenient, expensive, and prone to falling off during administration, compromising the trial's validity.
Innovation Solution
A carton designed to obscure the contents of a syringe, featuring a housing with an opening for the syringe tip, barrel, and flange, and flap portions that secure the syringe in place, preventing it from falling off during use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If makeshift syringe covers are used to obscure contents, then blinding is achieved, but the covers may fall off during administration compromising trial validity
Solution Approach 1:
The carton housing receives and contains the syringe within its chamber, with the syringe nested inside the housing structure. The flange of the syringe rests on the chamber floor while the tip protrudes through the aperture, creating a secure nested arrangement that prevents the syringe from falling off during administration.
Solution Approach 2:
The carton housing acts as an intermediary structure between the syringe and the external environment. It provides the obscuring function while the flange engagement mechanism serves as an intermediary securing system that reliably holds the syringe in place without requiring additional fastening components.
2Reliability
If opaque vials or blacked out syringes are used for blinding, then contents are obscured, but different packaging or decanting is required which is inconvenient and expensive
Solution Approach 1:
The carton housing serves multiple functions: it obscures the syringe contents through its opaque material, secures the syringe in place through flange engagement, and provides a user-friendly interface for administration. This multi-functional design eliminates the need for separate blinding solutions or modified syringe packaging.
Solution Approach 2:
The invention combines the blinding function, securing function, and administration interface into a single integrated carton housing structure. By merging these functions into one component, the system avoids the complexity and cost of multiple separate packaging elements or decanting procedures.
3Reliability
If the syringe is fully enclosed in the housing, then obscuring is maximized, but the tip needs to protrude for administration
Solution Approach 1:
The housing structure features a localized aperture that selectively exposes only the tip portion of the syringe while maintaining full enclosure of the barrel and contents. This local quality approach allows the tip to protrude for administration while the rest of the syringe remains obscured, balancing security with functionality.

AI summary
The present invention relates to a carton for obscuring the contents of the barrel of a syringe, the carton comprising; a housing; wherein the housing comprises an opening through which the tip, barrel and flange of a syringe may be introduced into the housing; a chamber with a first portion for receiving the barrel of the syringe and a second portion for receiving the flange of the syringe; and an aperture opposite to the opening, through which the tip of the syringe may protrude when the syringe is introduced into the housing.
