Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a wound cover that provides variable moisture vapor transmission rates while ensuring adequate oxygen supply to the wound, prevents biofilm formation, and allows for continuous access and visualization of the wound for treatment without disrupting the healing process.
Innovation Solution
A mobile wound cover with a design featuring a skin adhesion rim, a protective rim, and a removable cover that secures with a semi-transparent, double-sided adhesive, allowing for intermittent access to the wound while maintaining a hydrophilic environment and preventing accidental impact on the wound.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a wound cover is used to isolate the wound theater from excessive exposure to bacteria, then biofilm formation is prevented, but adequate oxygen supply to the wound is disrupted
Solution Approach 1:
The wound cover employs porous materials with controlled pore sizes that allow selective passage of oxygen molecules while blocking larger bacterial structures. The porous structure enables gas exchange through diffusion, maintaining oxygen supply to the wound theater while preserving the protective barrier against bacteria and biofilm formation.
Solution Approach 2:
The patent utilizes parameter changes in the form of variable moisture vapor transmission rates (MVTR) through the wound cover material. By adjusting the MVTR parameter, the cover can maintain optimal moisture levels for wound healing while allowing sufficient oxygen transmission. The cover can be configured with different MVTR values to match specific wound healing stages and requirements.
2Duration of action of stationary object
If a wound cover is used to provide moisture vapor transmission, then wound healing is supported, but access to the wound for debridement and treatment is blocked
Solution Approach 1:
The wound cover is segmented into multiple functional layers including an outer protective layer, a moisture vapor transmission layer, and an inner wound contact layer. This segmentation allows each layer to perform its specific function independently while maintaining overall accessibility. The cover can be designed with removable or adjustable portions that allow easy access to the wound for debridement and treatment without compromising the protective barrier.
Solution Approach 2:
The wound cover incorporates dynamic elements such as removable covers, adjustable straps, or flexible portions that can be easily modified between a closed protective state and an open accessible state. This dynamic design enables the cover to transition between providing continuous protection and allowing easy access for medical interventions, supporting both healing continuity and treatment accessibility.
3Ease of operation
If a removable cover is positioned close to the wound surface, then access is facilitated, but accidental impact to the wound occurs
Solution Approach 1:
The removable cover is designed to be positioned at a distance from the wound surface rather than touching it directly. This dimensional separation creates a protective air gap that prevents accidental impact to the wound while still allowing the cover to serve its protective and moisture-regulating functions. The cover can be suspended or supported in a way that maintains this distance, facilitating access during procedures while protecting against impact.
4Reliability
If a wound cover provides continuous protection, then biofilm formation is prevented, but interruptibility for treatment is reduced
Solution Approach 1:
The wound cover is designed with preliminary action elements such as pre-configured removable portions, pre-attached access panels, or pre-planned opening mechanisms that allow for easy and quick access to the wound when treatment is needed. These preliminary preparations enable the cover to maintain continuous protection during normal conditions while allowing rapid interruptibility for treatment without compromising the protective barrier during routine use.
