Hydrogel dressing sheet, made of hydrated polyurethane polymer containing glycerin. The dressing with a high water content (about 60%) is capable of dissipating moisture and absorbing wound exudate to a limited extent, thus providing a moist wound environment, supporting the wound healing process, stimulating granulation and epithelization. HydroTac transparent provides atraumatic dressing replacement, transparent, so the condition of the wound can be monitored even without removing the dressing. The semipermeable cover of the dressing protects against the penetration of bacteria. For the treatment of acute or chronic wounds with dry or mild discharge. Sterile, individually packed.
