Wound Dressing Garment with Hydrogel and Porous Film
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wound care treatments for pressure injuries, such as bed sores, are bulky, non-therapeutic, and lack breathability, requiring cumbersome application and frequent repositioning, especially for bedridden patients, and fail to effectively prevent ulcers on high-risk areas like heels and elbows.
Innovation Solution
A wearable wound dressing garment with a hydrogel layer, mesh layer for dispersal, adhesive layer for security, and transparent layers for monitoring, integrated into a sock or sleeve design that allows for easy application and secure positioning over wounds or at-risk areas, promoting healing and preventing ulcers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If foam based products are used for wound treatment, then the wound area is covered and protected, but the products become bulky and add heat to the wound area inhibiting healing
Solution Approach 1:
The patent uses a thin film dressing made of breathable material that conforms to the wound area without being bulky. This thin film design allows heat dissipation while maintaining wound protection, directly resolving the contradiction between reliable wound coverage and excessive heat accumulation.
Solution Approach 2:
The dressing incorporates porous breathable material that allows air and heat transmission. The porous structure enables thermal regulation by allowing heat to escape from the wound area while maintaining protective coverage, thus resolving the heat accumulation problem.
2Reliability
If individual dressing pieces are used for wound care, then the wound can be treated, but the application requires cutting and customization which is time consuming
Solution Approach 1:
The patent designs a universal dressing template with adhesive borders that can be applied to various wound shapes and sizes without cutting or customization. The single-piece design with flexible adhesive edges adapts to different wound geometries, eliminating the time-consuming cutting process while maintaining effective wound treatment.
Solution Approach 2:
The patent combines the dressing material, adhesive borders, and protective layers into a single integrated piece that requires no assembly or cutting. This merged design allows rapid application while maintaining all necessary wound care functions.
3Stability of the object's composition
If bedridden patients are required to remain in a single position, then the wound dressing remains stable, but the patients cannot shift about which is necessary for comfort and health
Solution Approach 1:
The patent employs dynamic adhesive borders that can stretch and conform as the patient moves between positions. The dressing material has elastic properties that allow it to accommodate patient movement while maintaining secure attachment, enabling both stability during rest and mobility when needed.
Solution Approach 2:
The dressing uses materials with variable mechanical properties that adapt to different states - maintaining firm adhesion when the patient is stationary for wound stability, while allowing controlled movement and repositioning when the patient needs to shift positions for comfort.
4Reliability
If a conformable wound dressing with high absorbency is used, then the wound can be effectively treated, but the dressing may wrinkle or appear bulky on protuberances like heels and elbows
Solution Approach 1:
The patent designs the dressing with pre-formed curved and contoured shapes that match common wound locations on body protuberances like heels and elbows. This curvature matching allows the dressing to conform smoothly to rounded body surfaces without wrinkling or bulkiness while maintaining high absorbency and treatment effectiveness.
Solution Approach 2:
The use of flexible thin film material allows the dressing to drape smoothly over contoured body surfaces without creating wrinkles or bulk. The material's flexibility enables it to adapt to complex body geometries while maintaining contact with the wound area for effective treatment.
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 garment provides a conformable, breathable, and easily applicable solution that stabilizes the wound dressing, reduces repositioning needs, and facilitates monitoring, while promoting healing and preventing ulcers, offering improved pain management and infection prevention.
