Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing IV catheter cover sleeves are difficult to adjust when both hands cannot be used, posing a challenge for secure and easy closure.
Innovation Solution
An IV catheter cover device with a single motion enclosure structure featuring extended fastening tabs and cuffs with elastic portions, allowing for secure closure and adjustment of the sleeves using a single motion, incorporating hook and loop fasteners for easy engagement and disengagement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional Velcro closure tabs are used along the open length of the sleeve, then the sleeve can be closed securely on the inside of the arm, but the sleeve becomes difficult to adjust when both hands cannot be used
Solution Approach 1:
The closure system is segmented into discrete components: a cuff at each end of the sleeve with Velcro tabs positioned at specific locations. Each cuff can be independently adjusted and secured, allowing the user to manipulate one end at a time rather than requiring simultaneous coordination of the entire sleeve closure.
Solution Approach 2:
The Velcro tabs are pre-positioned on the cuffs at optimal locations for engagement. The cuff structure itself is pre-configured with the fastening mechanism, so that when the user pulls the sleeve onto the arm, the cuffs are already positioned to engage with the Velcro tabs, eliminating the need for complex manual adjustment during application.
2Ease of operation
If the sleeve is designed to be open along its length for access, then the catheter can be easily accessed, but the sleeve lacks full enclosure protection
Solution Approach 1:
The sleeve transitions from a static fully-enclosed design to a dynamic structure with an open length portion that can be selectively covered. The cuff closures at each end can be adjusted to provide varying degrees of enclosure, allowing the user to balance accessibility with protection based on the situation.
Solution Approach 2:
The sleeve has different properties in different regions: the open length portion provides easy access and breathability, while the cuff portions at each end provide secure closure and protection. This local differentiation of enclosure quality allows simultaneous achievement of access and protection needs in different areas of the same device.

AI summary
Adjustable IV catheter cover devices are provided that include a sleeve defining a cavity therethrough. The sleeve can have first and second ends. First and second cuffs are integral to the sleeve at the respective first and second ends. The first cuff defines a first opening leading into the cavity and the second cuff defines a second opening leading into the cavity. The first and second cuffs each have an elastic portion, a fastening portion disposed next to a first end of the elastic portion, and a folding portion disposed between the elastic portion and the fastening portion. First and second fastening tabs are secured to the respective first and second cuffs at second ends of the respective elastic portions. The first and second fastening tabs are configured to engage the fastening portion of the respective cuffs to adjust the size of the respective first and second openings.
