Molnlycke Health Care Us, Llc Molnlycke Wound Dressing - Mepitel® One. A one sided version of Mepitel that utilizes the product benefits from Mepitel, but is easier to handle. Can be left in place for up to 14 days depending on the condition of the wound. This reduces the necessity for frequent primary dressing changes. The porous structure allows exudate to pass into an outer absorbent dressing. The Safetec layer prevents the outer dressing from sticking to the wound and ensures atraumatic dressing change. The Safetec layer seals around the wound edges, preventing the exudate to leak onto the surrounding skin, thus minimizes the risk of maceration.
