A composite wound dressing 1comprising an absorbent body 14 and an activated carbon cloth layer 13 that, in use, is in direct contact with the wound. The activated carbon cloth layer may be of a knitted form. The absorbent body may comprise foam, a gelling material, a superabsorbent material or a combination thereof, such foams optional formed of polyurethane. The wound dressing may further comprise antimicrobial, antifungal, antiseptic, anti-inflammatory agents, such as silver, polyhexamethylene biguanide or honey. The dressing may include a backing layer 11, which optionally forms a border on all sides around the carbon cloth, which may be formed of polyurethane film. A perforated wound contact layer 15 may also be included, which may extend beyond the edges of the carbon cloth on all sides to form a border. The perforations on the border section 22 may be smaller than those positioned over the activated carbon cloth layer 21. The wound contact layer may be formed of melt-blown polyurethane, and may further include an adhesive on the wound contacting face. |
