Sorbion Sana Gentle Dressings features the Hydration Response Technology and a unique 3-D structured wound contact layer made of polyethylene to maintain a moist environment for supporting tissue development. Sorbion Sana Gentle is indicated as a primary dressing for exuding wounds of varying aeiologies and is non-sensitizing. This makes it ideal for all patients even those with contact sensitivities. It can be worn up to seven (7) days. The sorbion inner core is made of mechanically modified cellulose fibres (cellulose and sodium polyacrylate) which are processed to produce an absorbent dressing pad. The production process involves binding together selected cellulose fibres and gel-forming polymers so that both components can interact and function together. Available in 5 sizes.
