Syringe Labeling Arrangement with Integrated Needle Trap
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional syringe protection systems are complex and costly, lacking a simple and cost-effective solution for reliable needle protection and first-opening verification.
Innovation Solution
A labeling arrangement for syringes featuring a needle trap integrated with a label and two flaps, where the second label flap is separable and attached to the needle protection cap, providing both needlestick protection and a clear indication of first-opening, achieved through a molded plastic needle trap and separable adhesive layers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional needle guard and needle trap systems are used, then reliable needle protection is achieved, but device complexity and manufacturing costs increase
Solution Approach 1:
The patent combines the needle trap function with the label structure by integrating a first label flap coupled to the needle trap and a second label flap coupled to the needle protection cap, both connected through the label. This merging of protection and labeling functions reduces device complexity while maintaining reliable needle protection.
Solution Approach 2:
The label structure serves multiple functions: it provides needle trap integration, opening verification through the separable second label flap, and labeling information. This multi-functionality eliminates the need for separate complex protection devices, reducing overall device complexity while maintaining protection reliability.
2Reliability
If conventional needle guard and needle trap systems are used, then reliable needle protection is achieved, but material costs and manufacturing costs increase
Solution Approach 1:
The needle trap is integrated into the label structure, combining two previously separate components (label and needle trap) into a single manufactured unit. This reduces material costs and simplifies manufacturing processes while maintaining reliable needle protection.
Solution Approach 2:
The label flaps and needle trap are formed from homogeneous material structures that can be manufactured together in a single process, reducing manufacturing complexity and cost while maintaining the protective function.
3Reliability
If a separate opening verification device is added, then first-opening verification is achieved, but device complexity increases
Solution Approach 1:
The opening verification function is merged into the label structure through the second label flap that is separable from the needle protection cap. When the cap is removed, the flap separates to provide visual verification, eliminating the need for separate verification devices.
Solution Approach 2:
The label structure simultaneously provides labeling information, needle trap integration, and opening verification through the separable second label flap. This multi-functionality achieves first-opening verification without adding separate complex devices.

AI summary
A labeling arrangement for a syringe includes a label adapted to be attached to the syringe body, and a needle trap adapted to receive and secure the syringe needle after use. A first label flap is coupled to the needle trap, and a second label flap separate from the first label flap has a predetermined severable design and is adapted to be attached to a needle protection cap surrounding the syringe needle and to form an opening detection element on the syringe. The first and second label flaps are connected to each other by the label so that, when the labeling arrangement is attached to the syringe in an operational state, the second label flap is severable when the syringe is opened by removing the needle protection cap and a second label flap section together with the needle protection cap is removable from the label and the syringe body.
