Universal IV Additive Port Cap with Tamper-Evident Housing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current tamper-evident cap solutions for IV containers are not universally compatible with differently dimensioned and configured additive ports, posing risks of unauthorized access and contamination, as they are often designed for specific brands and sizes, lacking effective protection and sterility maintenance during storage and transport.
Innovation Solution
A universally structured cap assembly with a housing and cover that can be adjusted to fit various additive ports, featuring a retaining structure and closure mechanism with ratchet segments, a flexible side wall, and a frangible connection, providing clear visual evidence of tampering and ensuring secure attachment to the port.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If tamper-evident cap solutions are designed for specific brands and sizes, then they provide secure protection for those specific containers, but they lack universal compatibility with differently dimensioned and configured additive ports
Solution Approach 1:
The cap assembly is designed with a universal housing structure that can accommodate multiple types of additive ports (e.g., Luer lock, Luer slip, threaded ports) through a single standardized interface. The housing includes internal retaining structures and sealing mechanisms that adapt to different port configurations without requiring different cap designs, thereby achieving multi-functionality and universal compatibility.
Solution Approach 2:
The cap assembly is divided into distinct functional segments: a housing portion that interfaces with the additive port, a seal portion that maintains sterility, and a tamper-evident cover portion. This segmentation allows each component to be optimized for its specific function while maintaining overall universal compatibility, as each segment can independently adapt to different port types.
2Adaptability or versatility
If a universal cap design is created to fit various additive ports, then compatibility improves, but the security and tamper-evident capabilities may be compromised
Solution Approach 1:
The cap assembly applies different quality characteristics to different segments: the housing portion provides universal mechanical interface qualities for compatibility, while the cover portion maintains high-security frangible connection qualities for tamper evidence. The seal portion incorporates sterile barrier qualities. This local differentiation of properties allows universal compatibility in the housing while preserving high security in the cover connection.
Solution Approach 2:
The frangible connection is pre-configured in a weakened state that requires deliberate breaking for access, and the tamper-evident features are pre-positioned to show visible indication before actual tampering occurs. The sterile seal is pre-applied to maintain sterility from manufacturing through storage and transport.
3Reliability
If the cap assembly uses a frangible connection for secure attachment, then tamper evidence is improved, but the ease of legitimate access may be reduced
Solution Approach 1:
The frangible connection is designed to break with partial force application rather than requiring complete destruction. The cover can be opened by applying force to break the frangible connection, which provides clear tamper evidence while requiring only moderate effort for legitimate access. This partial breaking action balances security indication with operational ease.

AI summary
A cap assembly universally structured for protectively enclosing differently dimensioned and configured additive ports of an IV container and including a housing, which may include a variably dimensioned interior, structured to receive the additive port therein, in an operative position. A cover is disposed in covering relation to the housing interior and a retaining structure is disposed within the housing in retaining engagement with the additive port. A closure structure is disposed on the housing in an attached orientation, structured to be resistant to detachment, concurrent to the operative position of the additive port within the housing. The operative position further includes the retaining structure disposed in retaining engagement with the additive port on the interior of the housing, concurrent to the attached orientation of said closure structure.
