The Paradigm Shift: Moist Wound Healing
Extensive clinical trials prove that maintaining a physiologically balanced moist wound bed accelerates epithelial migration up to 40% faster than traditional dry gauze dressings, while drastically reducing scarring and dressing-change trauma.
Advanced Dressing Spectrum
- Calcium Alginate: Derived from seaweed; converts to a soft hydrophilic gel upon contact with wound exudate. Ideal for high-exudate venous ulcers and cavity packing.
- Hydrocolloid Dressings: Waterproof outer polyurethane film with gel-forming carboxymethylcellulose mass. Perfect for partial-thickness abrasions, donor sites, and stage I-II pressure ulcers.
- Silver-Impregnated Antimicrobial Dressings: Sustained release of ionic silver (Ag+) provides broad-spectrum bactericidal action against MRSA and Pseudomonas aeruginosa in infected or colonized wounds.
