APPARATUS FOR ASPIRATING, IRRIGATING AND CLEANSING WOUNDS
First Claim
1. An apparatus for treating a wound, comprising:
- a wound dressing comprising;
a backing layer having a proximal, wound-facing face and a distal face;
a boss mounted to the backing layer at an opening in the backing layer and protruding distally therefrom;
a foam layer provided on a proximal side of the backing layer, wherein the foam layer is configured to be simultaneously applied together with the backing layer over the wound;
an adhesive on a periphery of the backing layer, wherein the adhesive is configured to attach the backing layer to skin around the wound; and
a membrane layer comprising a plurality of apertures configured to contact the wound, wherein the foam layer is in direct contact with the membrane layer and wherein the periphery of the backing layer extends beyond and surrounds the membrane;
a vacuum pump configured to apply negative pressure to the wound dressing; and
a fluid offtake tube configured to be mounted to the boss and provide fluid communication between the vacuum pump and the wound dressing.

Abstract
An apparatus for cleansing wounds in which irrigant fluid from a reservoir connected to a conformable wound dressing and wound exudate from the dressing are recirculated by a device for moving fluid through a flow path which passes through the dressing and a means for fluid cleansing and back to the dressing. The cleansing means (which may be a single-phase, e.g. microfiltration, system or a two-phase, e.g. dialytic system) removes materials deleterious to wound healing, and the cleansed fluid, still containing materials that are beneficial in promoting wound healing, is returned to the wound bed. The dressing and a method of treatment using the apparatus.
