Sterile Fluid Package with Integrated Needle-Free Transfer Plug
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current packages for sterile fluids, such as contrast media, require needle penetration or multiple operating steps for transferring contents to syringes or cartridges, posing risks of prick injuries and contamination.
Innovation Solution
A package with a connecting plug and cap that provides an integrated, needle-free connection system, allowing easy transfer to delivery devices like syringes or cartridges, featuring a Luer taper connection and tamper-evident features to ensure sterility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a rubber stopper with needle penetration is used, then the container can be sealed and accessed, but there is a risk of needle prick injuries and particle contamination
Solution Approach 1:
The invention extracts and removes the needle component from the fluid transfer process. Instead of using a rubber stopper that requires needle penetration, the system uses a dedicated connector that interfaces directly with syringes or cartridges, eliminating the need for needles and thereby removing the associated prick injury and contamination risks.
Solution Approach 2:
The invention introduces a dedicated connector as an intermediary component between the fluid container and the delivery device. This connector serves as a specialized interface that enables direct, sterile fluid transfer without requiring needle penetration of a rubber stopper, thus acting as a mediator that eliminates harmful needle-related effects.
2Ease of operation
If a rubber stopper with cap removal is used, then the container can be accessed by pouring or siphoning, but multiple operating steps are required for transfer
Solution Approach 1:
The invention prepares the container with a pre-installed dedicated connector that is ready for direct interfacing with syringes or cartridges. This preliminary configuration eliminates the need for multiple operational steps such as removing caps, pouring, or siphoning, as the connector is already in place to enable immediate and direct fluid transfer.
Solution Approach 2:
The invention merges the sealing function and the connection function into a single integrated dedicated connector. Instead of having separate components (cap, stopper, transfer adapter), the dedicated connector combines these functions, allowing the container to be both sealed and directly connectable to delivery devices, thereby reducing the number of operational steps required.
3Adaptability or versatility
If adaptors and transfer sets are used, then fluid transfer is possible, but the devices are not integrated with the container and are difficult to handle
Solution Approach 1:
The dedicated connector is designed with multi-functionality to interface with various delivery devices such as syringes and cartridges. It incorporates universal connection features (such as Luer taper connections) that enable compatibility with different device types while maintaining a simple, integrated structure that is easy to handle.
Solution Approach 2:
The invention merges the adapter or transfer set functionality directly into the container closure system. The dedicated connector is an integral part of the container assembly, eliminating the need for separate, complex adaptors that are difficult to handle. This integration maintains adaptability while simplifying the overall device structure and improving ease of handling.

AI summary
The present invention relates to a package, and more particularly to a package for sterile fluids, such as contrast media. More particularly the invention relates to a package comprising a container, a connecting plug and a cap. The package hence includes an integrated connection for easily transferring the content of the container of the package, e.g. to a syringe, a tube or a cartridge.
