The Vivo foams are antibacterial, antifungal and disinfectant foams; Vivo B (based on a silver glass ingredient), Vivo C (based on nano silver particles = Vivo Argentum), Vivo X (based on a quaternary ammonium salt) and Vivo PVP-I (based on polyvinylpyrolidone-iodine). These materials are suitable for the use in medical devices, class II. The foams are ideal for modern wound care. They absorb wound exudates, but guarantee a moist wound environment. Absorption capacity varies between 15 and 20 gram per gram product. The foams are non-linting, do not stick into the wound, have a cushioning effect and show high bendability, allowing easy fixing of the dressing to rounded body shapes. Active ingredients as antimicrobial agents, healing factors, pain relief drug or botanical extracts, can be incorporated and slowly released.
