Curative for wounds processes for treating a wound on a fabric structure of a living human or animal body and for the manufacture of the dressing and use of poly(3-hydroxybutyrate) in the form of fibres or powder substantially free from volatile solvent

摘要

A wound dressing (10; 110; 210) for dressing a wound (2; 102; 202) on a tissue structure of a living human or animal body comprising a lower section (1; 101; 201) which when the wound dressing dresses the wound is disposed adjacent the wound, the lower section being fluid permeable and comprising a bioresorbable material which promotes the healing process in the wound, and an upper section (3; 103; 203) which when the dressing dresses the wound overlies the lower section, the upper section being permeable to vapour and impermeable to bacteria. The wound dressing may be an integrally formed structure, an integrated structure or formed when the wound is dressed.
