Cutimed Sorbion Sachet S Dressing, 3" x 3" (7.5 x 7.5 cm). Cutimed Sorbion Sachet S is a versatile fibre dressing with high wearing comfort for primary wound contact and is suitable for moderately to highly exuding wounds. The inner core absorbs and irreversibly locks in wound exudate, debris and germs while maintaining a moist environment supporting the wound cleansing phase. The secret behind Sorbion Sachets highly absorbent core, Hydration Response Technology, binds together mechanically modified cellulose fibers and gel-forming polymers inside the wound dressing to provide increased binding capacity, optimized exudate handling capability and superior vertical uptake performance.
