Film Forming Foam (FFF) for Burn Wounds/Burnflex
Invention Summary:
Many available dressings on the market use latex, PVC, or polyurethane as barrier-like components to protect the patient from outside elements. The current use of these components presents a problem of waste and contamination. Other available options in the market are hydrogel-based dressings that may be coated in silver sulfadiazine,...
