Antiseptic Dead-End Cap for Luer Connectors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for reducing contamination of medical connectors, such as luer connectors, are prone to human error and lack a standardized method for storing and protecting the male luer connector when disconnected from the female connector.
Innovation Solution
An antiseptic dead-end cap with a base, annular walls, and a cylindrical center plug is designed to be securely attachable to both male and female luer connectors, featuring antiseptic materials that disinfect the connectors and prevent contamination, using threads for secure connection and antiseptic fluids like isopropyl alcohol for effective disinfection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If manual swabbing with disinfection is used, then contamination reduction is attempted, but human error increases and implementation reliability decreases
Solution Approach 1:
The cap structure enables self-disinfection through its design features. The tapered portion and internal chamber configuration allow the cap itself to apply antiseptic material to the connector surfaces without requiring manual swabbing operations. The system serves itself by using the mechanical action of putting on the cap to automatically distribute the antiseptic agent.
Solution Approach 2:
The cap is pre-loaded with antiseptic material in the internal chamber before use. This preliminary preparation eliminates the need for manual application during the disconnection process, ensuring consistent and reliable disinfection without human error. The antiseptic agent is ready for immediate application when the cap is positioned on the connector.
2Ease of operation
If connectors are disengaged for restroom facilities, then patient mobility is improved, but connector exposure to contamination increases
Solution Approach 1:
The cap serves as an intermediary protective element between the disconnected connector and the contaminated environment. When the connector is removed from the female luer, the cap can be quickly attached to the male luer connector, creating a protective barrier that prevents environmental contamination while allowing the patient to use restroom facilities without exposing the connector.
Solution Approach 2:
The cap is designed for rapid application before the connector is fully exposed or during the reconnection process. The pre-loaded antiseptic material is immediately activated when the cap is positioned on the connector, providing protective disinfection during the brief period when the connector is disconnected from the IV system.
3Device complexity
If no storage protection is provided, then device complexity is reduced, but contamination risk increases during storage
Solution Approach 1:
The cap performs multiple functions within a single simple structure: it protects the connector from contamination during storage, provides antiseptic disinfection, and enables secure reconnection to the female luer. This multi-functionality eliminates the need for separate storage containers and protection systems, maintaining simplicity while addressing contamination risks.
Solution Approach 2:
The cap's internal chamber configuration and tapered portion design enable it to automatically apply antiseptic material to the connector surfaces during the simple act of putting the cap on. This self-service mechanism provides continuous protection during storage without requiring complex active systems, power sources, or additional components.
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 antiseptic dead-end cap effectively reduces contamination by providing a secure, antiseptic barrier for medical connectors, ensuring they remain disinfected and protected during disconnection and storage, thereby enhancing hygiene and reducing the risk of infection.
Implementation Method 1
An antiseptic dead-end cap for use with a connector. Antiseptic material is on at least one of the inner surface of the first annular wall, the inner surface of the second annular wall, the outer surface of the second annular wall, and the outer surface of the cylindrical center plug.

AI summary
An antiseptic dead-end cap includes a base having first and second sides, a first annular wall extending from the first side of the base, a cylindrical center plug extending from the first side of the base, and a second annular wall extending from the second side of the base. The first annular wall has an outer and an inner surface. The cylindrical center plug has an outer and an inner surface, and is positioned within the first annular wall to form an annular chamber. The second annular wall has an outer and an inner surface, and defines a second chamber having an open end. The second chamber is further defined by the inner surface of the cylindrical center plug. An antiseptic material is on at least one of the first annular wall inner surface, second annular wall inner surface, second annular wall outer surface, and cylindrical center plug outer surface.
