Patent

CA 2641485

A wound dressing system includes a fluid permeable support member for positioning within a wound and adapted to generally conform to a topography of a wound, a plurality of beads supported by the support member, an outer member for positioning over the wound to substantially enclose the beads and a conduit for supplying reduced pressure to the wound. The support member is adapted to permit exudates from the wound to pass therethrough. The beads are characterized by having sufficient rigidity to substantially maintain respective shapes thereof to thereby facilitate passage of the exudates through spaces or passages defined between adjacent beads. The beads may comprise glass, an acrylic or a polymeric material. The support member may comprise a polymeric or fabric material. The support member may be an enclosure member or pouch which houses the beads. Multiple pouches are also envisioned.

L'invention porte sur un pansement chirurgical comportant, un support perméable aux fluides se plaçant dans la plaie et se configurant sensiblement à sa forme; des perles reposant sur le support; un élément extérieur se plaçant sur la plaie et confinant sensiblement les perles; et un conduit permettant de mettre la plaie sous une pression réduite. Le support se laisse traverser par les exsudats de la plaie. Les perles, de verre ou de matériau acrylique ou polymère, ont une rigidité suffisante pour conserver leur forme et donc favoriser le passage de l'exsudat entre elles. Le support, de polymère ou de tissus, peut être un sac ou une ou des poches renfermant les perles.
