Sulfonic Acid Wound Debridement Formulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional treatments for chronic wounds, including debridement methods, have been ineffective in healing chronic wounds due to the presence of necrotic tissue that acts as a reservoir for bacterial growth and promotes inflammation, impairing cellular migration and healing.
Innovation Solution
A liquid or gel formulation comprising phenolsulfonic acid, guaiacolsulfonic acid, free sulfuric acid, and water, or benzenesulfonic acid, phenolsulfonic acid, and colloidal silica, applied topically to the wound, which acts as both a mechanical and chemical debridement agent, desiccating necrotic tissue and biofilms, and disrupting bacterial structural integrity, thereby promoting wound healing and preventing infections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional debridement methods (autolytic, enzymatic, mechanical, surgical) are used to remove necrotic tissue, then the wound bed is cleared, but the necrotic tissue acts as a reservoir for bacterial growth and promotes inflammation that impairs cellular migration and healing
Solution Approach 1:
The patent applies chemical parameters (strong acids like phenolsulfonic acid, guaiacolsulfonic acid, and sulfuric acid) to change the state of necrotic tissue from resistant to easily removable, while simultaneously achieving bacterial destruction and biofilm disruption. This chemical parameter change resolves the contradiction by making debridement both easy and effective at the same time.
Solution Approach 2:
The formulation combines multiple sulfonic acid compounds with colloidal silica to create a composite debridement agent that simultaneously performs mechanical debridement, chemical necrotic tissue dissolution, bacterial destruction, and biofilm disruption. This composite approach achieves both ease of debridement and reliable healing outcomes.
2Stability of the object's composition
If necrotic tissue is left in the wound, then the wound structure is maintained, but it delays healing by acting as a reservoir for bacterial growth and containing inflammatory mediators
Solution Approach 1:
The patent extracts and removes necrotic tissue from the wound bed through chemical debridement action of the sulfonic acid formulation. The formulation selectively targets and removes necrotic tissue while preserving healthy tissue, thereby eliminating the bacterial reservoir and inflammatory mediators to enable effective healing.
Solution Approach 2:
The formulation performs preliminary chemical debridement and bacterial destruction before the wound healing process can effectively begin. By pre-treating the wound to remove necrotic tissue and kill bacteria, the formulation prepares the wound bed for subsequent healing activities, thereby accelerating the overall healing rate.
3Reliability
If strong chemical agents are used to destroy bacterial structural integrity, then antibiotic-resistant and persistent bacteria are eliminated, but the formulation must be carefully controlled to avoid damaging healthy tissue
Solution Approach 1:
The formulation exhibits local quality by being selectively active only where necrotic tissue and bacteria are present. The sulfonic acid compounds concentrate their destructive action on damaged tissues and microbial structures while sparing healthy viable tissue, thereby achieving reliable bacterial elimination without causing harmful damage to healthy tissue.
Solution Approach 2:
The patent converts the harmful presence of necrotic tissue and biofilm into a benefit by using the formulation's strong chemical action to specifically target and destroy these harmful elements. The same chemical strength that could potentially damage healthy tissue is instead directed at pathological materials, turning a potential harm into a therapeutic benefit.
