Disinfection Cap With Automatic Wiping for Medical Connectors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing disinfection caps for medical connectors often fail to provide stable and sufficient disinfection due to variations in user skill and design limitations, such as requiring manual rotation or pressing, which can lead to incomplete germ and dirt removal.
Innovation Solution
A disinfection cap with a cap main body and a movable wiping body impregnated with antiseptic solution, featuring a cap side locking section that engages with the medical connector side locking section, allowing for rotational and axial movement to effectively wipe the top face wall, inner peripheral face, and valve body surfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual rotation and pressing are used to wipe the medical connector, then the disinfection process can be performed, but the disinfection effectiveness varies due to user skill differences
Solution Approach 1:
The wiping body is designed to automatically perform the wiping action when the cap is attached to the medical connector. The relative movement between the wiping body and the cap main body occurs automatically during attachment, eliminating the need for manual rotation or pressing operations by the user.
Solution Approach 2:
The wiping body is configured to move relative to the cap main body during the attachment process. This dynamic design allows the wiping body to automatically contact and wipe the male connector connection section surfaces, converting the static manual operation into a dynamic automatic process.
2Reliability
If the cap main body is pressed against the male connector connection section and rotated manually, then wiping can be performed, but stable and sufficient disinfection is difficult to achieve
Solution Approach 1:
The device performs the wiping function automatically through the relative movement between the wiping body and cap main body during attachment. The impregnation section automatically contacts and wipes the target surfaces without requiring complex manual manipulation or additional operational steps.
3Reliability
If the wiping body is held by the cap main body with locking engagement, then stable wiping can be performed, but the device structure becomes more complex
Solution Approach 1:
The locking sections serve dual functions: they secure the cap main body to the medical connector and simultaneously provide the relative movement necessary for the wiping body to contact and wipe the male connector connection section surfaces. This multi-functionality reduces the need for separate complex mechanisms.

AI summary
A disinfection cap is provided with a cap main body and a wiping body held by the cap main body. The cap main body includes a cap side locking section that prevents pullout of the cap main body by engagement with a medical connector side locking section. The wiping body includes an impregnation section impregnated with an antiseptic solution and is movable with respect to the cap main body so as to wipe at least the surface of a top face wall, the inner peripheral face of an opening of the top face wall, or the surface of a valve body in a male connector connection section of a medical connector with the impregnation section with the cap side locking section engaged with the medical connector side locking section.
