  • a fluid flow path, comprising;

    a conformable wound dressing, comprising a backing layer which is capable of forming a relatively fluid-tight seal or closure over a wound and a wound-facing face, at least one inlet lumen passing through and/or under the wound-facing face and in communication with at least a fluid reservoir, and at least one outlet lumen passing through and/or under the wound-facing face, wherein a relatively fluid-tight seal or closure is formed over the wound at the point at which each inlet lumen and each outlet lumen passes through and/or under the wound-facing face;

    a means for fluid cleansing in communication at least with the outlet lumen comprising a two-phase system configured to remove materials deleterious to wound healing from fluid removed from the wound by bringing fluid removed from the wound into direct or indirect contact with a second fluid, wherein fluid removed from the wound and the second fluid are separated by an integer;

    a fluid recirculation lumen for directing cleansed fluid from the means for fluid cleansing back into the inlet lumen;
