Apertured Hydrogel Dressing for Percutaneous Device Comfort
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Percutaneous devices, such as diabetic pumps and Huber needles, cause skin irritation and increase infection risks due to prolonged use, with existing dressings failing to adequately address comfort and microbial growth inhibition.
Innovation Solution
An apertured hydrogel medical dressing with antimicrobial properties and adhesive capabilities, featuring a base sheet that forms a tab to secure the dressing and prevent adhesion to the injection mechanism, while allowing for easy removal and providing comfort and antimicrobial protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If a percutaneous device is used for extended period, then fluid delivery function is maintained, but skin irritation and infection risk increase
Solution Approach 1:
The patent introduces a hydrogel dressing as an intermediary barrier between the percutaneous device and the skin. This hydrogel layer provides a protective interface that reduces direct contact between the device and skin, thereby minimizing skin irritation and infection risk while allowing extended device use to continue
Solution Approach 2:
The patent modifies the physical and chemical parameters of the dressing by using hydrogel material with specific properties (moisture content, pH, antimicrobial agents). These parameter changes enable the dressing to provide enhanced comfort and antimicrobial protection, addressing the harmful effects of extended device use
2Reliability
If a dressing is applied to protect skin around percutaneous device, then infection risk decreases, but device complexity increases
Solution Approach 1:
The patent combines multiple functions into a single integrated hydrogel dressing layer. This layer simultaneously provides skin protection, moisture management, antimicrobial action, and comfort, eliminating the need for separate complex multi-layer structures and reducing overall device complexity while maintaining reliability
3Quantity of substance
If hydrocolloid material is used in dressing, then exudate absorption is improved, but material remaining on skin increases
Solution Approach 1:
The patent changes the material parameter from traditional hydrocolloid to hydrogel, which has superior absorption characteristics and can be removed more easily from skin. This parameter change maintains exudate absorption capacity while reducing the amount of material that remains on the skin after use
