Tubular Absorbent Cleaning Device for ENFit Connector Moat Drying
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The ENFit medical connector's geometry creates challenges in maintaining cleanliness, leading to drying and caking of enteral feeding solution, which results in difficulty connecting and disconnecting devices and potential microbial growth, as traditional cleaning methods like brushes are not effective in removing liquid or drying the narrow 'moat' region.
Innovation Solution
A tubular absorbent cleaning device is designed to fit within the ENFit connector's moat, absorbing and drying any liquid, and can be used alone or with a brush to remove dried solution, ensuring the area is clean and dry to prevent bacterial growth.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If traditional brushes are used to clean the moat region, then dried solution can be removed, but liquid solution cannot be effectively absorbed or dried
Solution Approach 1:
The cleaning device combines brush bristles for mechanical removal of dried solution with an absorbent material layer for liquid absorption. This composite structure allows the device to perform both mechanical cleaning and drying functions simultaneously, resolving the contradiction between removing dried solution and absorbing liquid.
Solution Approach 2:
The cleaning device has different regions with different properties: the brush bristles are concentrated in areas needing mechanical scrubbing, while the absorbent material is distributed in areas needing liquid absorption. This localized differentiation allows each part to perform its specific function optimally.
2Ease of operation
If the moat region is not cleaned, then connector operations are simple, but drying and caking occurs leading to connection difficulties
Solution Approach 1:
The cleaning device is designed to be used immediately after disconnecting the administration set from the feeding tube, before the solution can dry and cake in the moat region. This preliminary cleaning action prevents the formation of dried residues that would cause future connection difficulties.
3Ease of manufacture
If liquid remains in the moat after cleaning, then cleaning process is simple, but microbial growth occurs causing contamination
Solution Approach 1:
The absorbent material in the cleaning device has a porous structure that allows it to rapidly absorb and wick away liquid solution from the moat region. This porous structure provides large surface area for liquid absorption, effectively drying the region to prevent microbial growth.

AI summary
A cleaning device is configured access and remove fluid from and dry a moat region defined by a hub of a medical connector, thereby minimizing the potential for bacterial growth in the hub. The cleaning device takes the form of an absorbent block which can be inserted into the moat by extending about a central male fitting and into a gap between the male fitting and the inner wall of a female hub of the medical connector. In a preferred embodiment of the invention, the block takes the form of a tubular cylinder particularly configured for use on ENFit medical connectors wherein the absorptive feature of the cleaning device can be employed alone or in combination with another cleaning tool used to first remove any existing dried and caked solution in the hub before removing residual cleaning fluid from the moat.
