Water-Soluble Wound Dressing Adhesive for Gentle Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional wound dressings, surgical tapes, and cannula dressings cause discomfort and further wound damage during removal due to the need for pulling off adhesive materials, which is painful and counter-productive, especially for elderly patients and cosmetic procedures.
Innovation Solution
Adhesive components made of water-soluble paper or polymer that can be easily removed with water or a wet sponge, allowing gentle removal without disturbing the absorbent pad or skin, and optionally covered by a removable film for added protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional adhesive materials (sticky fabric, adhesive plastic film) are used to secure wound dressings, then the dressing can be held securely against the skin, but removal causes pain and further wound damage
Solution Approach 1:
The adhesive material's solubility parameter is changed from traditional permanent adhesives to water-soluble adhesives. This allows the adhesive to maintain strong bond strength during use but enables painless removal through water dissolution, eliminating wound damage during detachment
Solution Approach 2:
The adhesive layer is designed as a temporary, disposable component that dissolves after use. Rather than being removed mechanically, the adhesive layer is discarded by water dissolution, eliminating the harmful mechanical removal process while maintaining secure attachment during the treatment period
2Strength
If traditional adhesive materials are used, then the dressing remains firmly attached, but removal requires tearing which is uncomfortable and counter-productive
Solution Approach 1:
The adhesive material transitions from permanent to water-soluble properties. This parameter change allows the adhesive to provide strong bond strength during application while enabling easy, painless removal through water dissolution, eliminating the need for forceful tearing
Solution Approach 2:
The mechanical removal process (tearing, pulling) is replaced by a chemical dissolution process. Water dissolves the adhesive material, eliminating the need for mechanical force and associated pain, making removal gentle and comfortable
3Reliability
If adhesive materials are used to secure cannula dressings, then the cannula is held in place, but removal causes skin pulling and discomfort
Solution Approach 1:
The adhesive material's solubility is changed to water-soluble. This allows the adhesive to securely fix the cannula dressing during use but enables painless removal through water dissolution, eliminating skin pulling and discomfort associated with traditional adhesive removal
Applied Scientific Principles
