Grooved Foam Debridement Pad for Wound Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wound care devices using foam for debridement often lack effective mechanisms to collect debris and slough from wounds, which can obstruct healing and may damage fragile wounds due to uneven pressure distribution.
Innovation Solution
A wound care device comprising a first foam layer with grooves and ridges on its surface and a second foam layer, where the grooves are designed to collect debris and the continuous edge portion provides robustness, allowing for even pressure distribution and gentle wound cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If foam material is used for debridement, then gentle wound cleaning is achieved, but debris collection capability is insufficient
Solution Approach 1:
The foam layer is segmented into multiple functional zones: a central portion with grooves and ridges for debris collection, and a continuous edge portion for structural support. This segmentation allows different regions to perform specialized functions, improving both debris collection and debridement effectiveness simultaneously.
2Object-affected harmful factors
If foam is made softer for gentle cleaning, then wound damage is reduced, but tensile strength and structural integrity deteriorate
Solution Approach 1:
Different regions of the foam are given different properties: the central portion contains grooves and ridges that provide mechanical strength for debris collection, while the continuous edge portion provides structural integrity. This local differentiation allows the foam to be gentle on wounds while maintaining overall structural strength.
3Object-affected harmful factors
If grooves are added to foam surface for debris collection, then debris acceptance is improved, but foam structural integrity worsens
Solution Approach 1:
The foam structure is differentiated into a central portion with grooves and ridges for debris collection, and a continuous edge portion without grooves for structural support. This local quality differentiation ensures that grooves are placed only where needed for debris acceptance, while the continuous edge maintains overall foam integrity.

AI summary
A wound care device for debriding a wound, said device is in the form of a foam pad with two layers of different foams. At one surface of the device is provided a pattern of grooved at the central portion. The grooves improve the ability of removing and collecting debris from a wound during cleaning of such.
