Wound dressing for topical negative pressure therapy

摘要

The dressing comprises a pouch 10 consisting of fluid permeable outer layers 12, 14 enclosing a volume of permeable material 16, for example gauze. A plurality of these pouches 10 are placed within a wound cavity 20 to fill and conform to the shape of the wound cavity 20 and sealed within the wound cavity with a conduit 22 for supplying reduced pressure to the wound or provision for negative pressure may be provided on the wound cover 23. The outer layers 12, 14 of the pouches are non- adherent for ease of dressing changes and may be impregnated or coated with anti-microbials or medicaments to promote wound healing or with active charcoal to reduce wound odour. The pouches 10 can be manufactured in various sizes, shapes and in a sheet or a roll.
