Gap-Patterned Foam Wound Dressing Honey Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for an improved gap-patterned wound dressing that effectively disperses honey throughout a wound treatment zone while allowing for easy handling and efficient absorption of exudates, as existing honey-based dressings face challenges with honey distribution and exudate management.
Innovation Solution
A gap-patterned medical grade foam dressing with a patterned foam structure featuring hexagon-shaped honey-dosed areas and foam gaps, where the foam is made of absorbent and porous polyether polyurethane, allowing exudates to collect in gaps and disperse honey evenly across the wound, with a dry edge for handling and a breathable barrier for protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If honey is applied to the entire surface of the foam dressing, then honey coverage is maximized, but honey distribution control and handling ease deteriorate
Solution Approach 1:
The foam dressing surface is divided into discrete hexagonal foam cells, with honey applied only to specific cells rather than the entire surface. This segmentation allows controlled honey distribution while maintaining handling ease, as the honey is confined to discrete locations rather than coating the whole dressing surface.
Solution Approach 2:
Different regions of the foam dressing have different properties: some foam cells are dosed with honey while others remain gap areas without honey. This local differentiation enables precise control over where honey is delivered to the wound, improving distribution control while the undosed gap areas maintain handling characteristics.
2Quantity of substance
If honey is dosed in large continuous areas, then honey delivery capacity increases, but exudate collection efficiency decreases
Solution Approach 1:
The dressing structure segments the surface into alternating honey-dosed foam cells and gap areas. The gap areas serve as collection zones for exudate, while the dosed cells provide honey delivery. This segmentation enables both high honey delivery capacity through multiple dosed cells and efficient exudate collection through the gap areas.
Solution Approach 2:
The gap areas act as intermediary zones between the honey-dosed foam cells and the wound bed. These gap areas collect exudate from the wound and facilitate its interaction with the honey in the dosed cells, improving overall exudate management while maintaining honey delivery capacity.
3Quantity of substance
If the foam structure is made fully porous for absorbency, then exudate absorption increases, but honey retention decreases
Solution Approach 1:
The foam dressing exhibits local quality differentiation: the overall foam structure is porous to enable exudate absorption, but the specific foam cells dosed with honey have controlled porosity to retain honey. The gap areas maintain high porosity for absorption, while the honey-dosed cells provide localized honey retention through controlled foam cell structure.
Solution Approach 2:
The foam structure is segmented into different functional zones with different porosity characteristics. The honey-dosed foam cells have structure optimized for honey retention, while the gap areas and overall foam matrix provide porosity for exudate absorption. This segmentation resolves the contradiction between absorption and retention.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The dressing facilitates controlled, natural osmotic delivery of honey, enhances exudate absorption, and improves handling ease, optimizing honey distribution and absorption efficiency beyond previous honey-based dressings.
Implementation Method 1
the foam includes a thickness that is sufficient to hold a specific amount of honey about 50% by total weight to about 75% by total weight of the foam structure and honey, in combination
Implementation Method 2
a wound in contact with the gap patterned side discharges an exudate which substantially collects in the individual ones of the foam gaps causing honey in the individual ones of the honey dosed areas to be substantially dispersed throughout a wound treatment zone

AI summary
A gap-patterned wound dressing, including a patterned foam structure having a gap patterned side and a non-gap patterned side, wherein the gap patterned side includes a pattern of foam gaps disposed between foam areas dosed with honey, where the pattern of foam gaps is formed by the honey dosed areas; and wherein a wound in contact with the gap patterned side discharges an exudate which substantially collects in the individual ones of the foam gaps causing honey in the individual ones of the honey dosed areas to be substantially dispersed throughout a wound treatment zone.
