A composite wound dressing 1 comprising a superabsorbent material 12, and a layer of activate carbon cloth 13. The wound dressing may be arranged such that wound exudates passes through the layer of carbon cloth before being absorbed by the superabsorbent material. The activated carbon cloth may be of knitted form and may be position directly below the superabsorbent material and bond or held thereto. The dressing may include a further absorbing body located between the activated carbon cloth layer and the superabsorbent material. The carbon cloth layer may be the wound contacting layer, or an additional wound contact layer may be provided 14, which can be formed of a non-woven blend of polyester and viscose or a melt-blown polyurethane film with a silicone gel. The superabsorbent material may comprise a polymeric superabsorbent material, such as alginate, polyacrylate, polyacrylamide copolymers, ethylene maleic anhydride copolymer, carboxymethylcellulose, polyvinyl alcohol, polyethylene oxide or starch-grafted copolymers of polyacetonitrile. The wound dressing may further comprise antimicrobial, antiseptic, antifungal or anti-inflammatory agents, such as silver, polyhexamethylene biguarnide or honey. The wound dressing may further comprise a backing layer 11 formed of polyurethane film and extend beyond all the edges of the carbon cloth to form a border around said carbon cloth. |
