Infusion Set Packaging With Retaining Means And Release Layer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The insertion of infusion devices is often difficult, inflexible, and prone to contamination, as existing technologies lack stability and proper handling mechanisms during the insertion process.
Innovation Solution
A packaging system that combines an infusion set with a needle hub and an inserter or handle, featuring an impenetrable part for protection and a removable part for easy access, with adhesive retention and release mechanisms to minimize contamination and ensure stable positioning during insertion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the infusion set is held in the packaging during insertion, then stability and positioning are maintained, but the insertion process becomes more complex requiring additional handling steps
Solution Approach 1:
The packaging is designed to pre-position the infusion set and needle hub in a stable, ready-to-use configuration before insertion. The retaining means are pre-configured to hold the components in the correct orientation, so that when the user removes the packaging, the insertion is already prepared and stabilized, reducing the need for additional handling steps during the actual insertion process.
2Ease of operation
If the release layer is fastened to the impenetrable part, then the release layer is automatically removed when the infusion set is removed, but the packaging structure becomes more complex
Solution Approach 1:
The release layer is merged with the impenetrable part of the packaging through fastening, creating a single integrated component. This ensures that when the user removes the infusion set from the packaging, the release layer is automatically removed as well, providing ease of operation without requiring separate manual removal steps. The merging of these functions into a unified structure resolves the contradiction between operational simplicity and structural complexity.
3Ease of operation
If the secondary device forms a stronger connection with the infusion set than with the packaging, then the infusion set can be easily removed by pulling the secondary device, but the connection strength requirements increase
Solution Approach 1:
The connection between the secondary device and the infusion set is designed with local quality variations - the connection point is specifically engineered to have enhanced strength characteristics at the interface between the secondary device and infusion set, while maintaining ease of removal. This localized strengthening at the critical connection point allows for simple pull-away removal without requiring excessive force throughout the entire assembly, resolving the contradiction between ease of operation and connection strength requirements.
Applied Scientific Principles
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 packaging system simplifies and stabilizes the insertion process, reducing contamination risks and allowing for easy removal of the infusion set while maintaining sterility, with the option for either releasable or unreleasable connections to the secondary device.
Implementation Method 1
the proximal side of the infusion set is provided with an adhesive
Implementation Method 2
the adhesive can be covered with a release layer

AI summary
The present invention relates to a packing for an infusion set. An infusion set for intermittent or continuous administration of a therapeutical substance, such as insulin, comprises an infusion part having a cannula penetrating the skin of a patient and a connector which connects the infusion part with a medical device such as an adaptor for a syringe or an insulin pump. The insertion of the infusion part will be performed with an insertion needle which is delivered together with the infusion part under sterile conditions. The packaging comprises an impenetrable part (7) protecting the surroundings from the insertion needle and a removal part (8) which is to be removed by the user before applying the infusion part. The inner surface of the impenetrable part (7) is provided with means (7a) for releasable retaining at least a part of the infusion set.
