Topical Wound Treatment Composition Using Hydrogen Peroxide Generator
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wound healing treatments often neglect the pH value's influence on the healing process, with hydrogen peroxide not consistently showing positive results, and existing compositions are not adaptable for various wound types.
Innovation Solution
A topical wound treatment composition is created by dispersing a hydrogen peroxide generator (e.g., urea peroxide) and an alkaline powder into an emollient, which reacts with water to generate oxygen, aiding in wound healing, with a pH-adjusted formulation to enhance the healing process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If hydrogen peroxide is used to accelerate reepithelization and treat infection, then wound healing should be improved, but the results are inconsistent and do not support the hypothesis
Solution Approach 1:
The patent changes the chemical parameters by combining hydrogen peroxide with alkaline substances (sodium bicarbonate, sodium carbonate) to create a buffered system that maintains pH between 7-9. This parameter adjustment stabilizes the chemical environment, ensuring consistent oxygen generation and reliable wound healing effects across different wound types and conditions.
Solution Approach 2:
The patent creates a composite treatment composition by combining hydrogen peroxide with alkaline powders and emollients. This composite approach integrates multiple functional components: hydrogen peroxide for oxygen generation, alkaline substances for pH buffering, and emollients for wound protection. The synergistic combination ensures consistent and reliable healing outcomes that neither component achieves alone.
2Ease of operation
If a single wound treatment composition is used, then ease of application is improved, but adaptability to different wound types and phases is reduced
Solution Approach 1:
The patent designs a universal wound treatment composition that performs multiple functions: it generates oxygen for tissue regeneration, buffers pH to support different healing phases, provides emollient protection, and prevents infection. This multi-functional formulation can be applied to various wound types (surgical incisions, burns, ulcers) and healing phases without requiring different products, thus achieving both ease of use and adaptability.
Solution Approach 2:
The composition incorporates pH-buffering alkaline substances that can adapt to different wound environments and healing phases. The buffered system maintains optimal pH (7-9) regardless of the initial wound condition, allowing a single composition to effectively treat diverse wound types and support different phases of healing from inflammation to reepithelization.
3Reliability
If pH value is controlled to be alkaline for skin-graft take-rate, then graft survival is improved, but this conflicts with the traditional assumption that low pH is favorable for wound healing
Solution Approach 1:
The patent deliberately changes the pH parameter from acidic to alkaline (pH 7-9) to support skin-graft take-rate and other healing processes. By incorporating alkaline substances like sodium bicarbonate and sodium carbonate, the composition maintains a stable alkaline environment that promotes reliable graft survival and healing, overturning the traditional low-pH assumption.
Solution Approach 2:
The buffered alkaline system provides pH feedback control, automatically maintaining the optimal pH range (7-9) through the buffer capacity of the alkaline substances. This feedback mechanism ensures pH stability and reliability regardless of variations in wound exudate or environmental conditions, consistently supporting high skin-graft take-rates.
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 composition effectively promotes wound healing by generating treatment-effective amounts of oxygen, improving wound appearance and healing rates, as demonstrated in post-surgical wound healing studies.
Implementation Method 1
the hydrogen peroxide generator and/or the alkaline compound diffuse into one another, causing a chemical reaction that generates treatment-effective amounts of oxygen to occur
Implementation Method 2
When topically applied to a wound and water from the surrounding environment diffuses into the composition
Implementation Method 3
the hydrogen peroxide generator and/or the alkaline compound diffuse into one another

AI summary
A topical wound treatment composition comprises a hydrogen peroxide generator; alkaline powder; not more than 5 percent by weight of water; additional topical active agent if desired, and emollient (preferably hygroscopic emollient) to balance. When topically applied to a wound and water from the surrounding environment diffuses into the composition, the hydrogen peroxide generator and/or the alkaline compound diffuse into one another, causing a chemical reaction that generates treatment-effective amounts of oxygen to occur. The oxygen can then diffuse out of the composition and aid in wound treatment or healing.
