Cosmopor® DryBarrier Cosmopor® Advance and Cosmopor® Antibacterial include the Dry Barrier® Technology which allows the wound exudates to penetrate to the pad but not be released from it – even under pressure. This combination of high absorption capacity and extremely low rewetting permits the postoperative dressing to stay on the wound longer. The already tried and tested product benefits of Cosmopor® are retained. Both products are sterile, self-adhesive wound dressings made of soft non-woven with a highly absorbent pad. The wound pad of Cosmopor Antibacterial contains also an inner layer coated with metallic silver having an antibacterial activity concerning gram positive and gram negative bacteria. The wound pad of both products includes also a wound contact layer which prevents the wound pad from adhering to the wound.
