Single-Use Vascular Access Caps with Destructible Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vascular access devices, such as needlefree connectors, contribute to healthcare-associated infections due to contamination risks, despite the use of disinfecting caps and scrubbing protocols, as they can be reused or not effectively protected, leading to ongoing catheter-related bloodstream infections.
Innovation Solution
Single-use caps designed to securely fit over vascular access ports, featuring a separating mechanism that renders them unusable after removal, ensuring compliance with infection prevention protocols by preventing reuse and providing antimicrobial protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If reusable caps are used on vascular access ports, then cost is reduced and resource utilization is improved, but infection risk increases due to potential contamination and improper reuse
Solution Approach 1:
The patent implements a disposable cap system where each cap is designed for single use only. The cap includes a destructible feature that prevents reuse after removal from the vascular access port, ensuring that a new sterile cap is used for each patient access event. This eliminates the infection risk associated with reusable caps while maintaining cost-effectiveness through efficient resource utilization.
Solution Approach 2:
The cap is pre-packaged in sterile condition and applied to the vascular access port before patient contact. The destructible feature is pre-configured in the cap design, ensuring that the cap cannot be reused. This preliminary preparation and design feature guarantee infection prevention by eliminating any possibility of cross-contamination between patients.
2Ease of operation
If caps are designed to be easily removable for patient access, then ease of operation is improved, but the risk of accidental removal or improper handling increases
Solution Approach 1:
The cap is segmented into two functional parts: a removable portion that allows easy detachment for patient access, and a destructible feature that remains on the port or is disposed of with the cap. This segmentation enables healthcare providers to easily remove the cap when needed while the destructible feature prevents accidental reuse or improper handling.
Solution Approach 2:
Different portions of the cap have different properties: the outer surface is designed for easy gripping and removal, while the inner portion includes a destructible feature with specific mechanical properties that prevent reuse. This local differentiation of qualities allows the cap to be both easy to remove and resistant to accidental improper handling.
3Reliability
If caps provide extended protection time without removal, then infection prevention is improved, but the need for frequent monitoring and potential removal increases complexity
Solution Approach 1:
The cap is designed as a self-contained protective device that maintains sterility without requiring external monitoring or intervention. The destructible feature automatically prevents reuse after removal, and the cap's material and design maintain its protective function throughout the intended duration. This self-service design eliminates the need for complex monitoring systems or frequent checks.

AI summary
This invention concerns improved single use caps or covers for vascular access devices such as needlefree connectors that are used, for example, in intravenous administration sets and extension sets. Removal of a single use cap or cover according to the invention from a vascular access device destroys the cap such that the cap cannot be reused. Said single use caps or covers will help ensure compliance with infection prevention protocols in healthcare settings, which will assist in reducing incidences of healthcare-associated infections (HAIs), particularly catheter-related blood stream infections. Assemblies and kits including said caps or covers, for example, IV administration and extension sets that include one or more needlefree connectors, as well as methods for using said caps or covers, are also described.
