Wound cleansing apparatus
First Claim
1. An apparatus for treatment of a wound, comprising:
- a member comprising a central portion and a plurality of flow channels extending radially therefrom;
wherein each of the plurality of flow channels defines a flow path that is separate along its length from the flow paths defined by each of the other of the plurality of flow channels and the plurality of flow channels are interconnected only at the center portion of the member;
a relatively liquid impermeable backing layer disposed over the member and capable of forming a relatively fluid-tight seal or closure over the wound; and
a conduit having an end portion disposed beneath the backing layer and in fluid communication with each of the plurality of the flow channels via the central portion of the member.

Abstract
An apparatus for cleansing and promoting tissue growth in wounds, in which irrigant fluid optionally containing cell nutrients and/or other physiologically active material 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, a biodegradable scaffold in contact with the wound bed and a means for fluid cleansing and back to the dressing. The apparatus has means for supplying thermal energy to the fluid in the wound. The cleansing means (which may be a single-phase, e.g. micro-filtration, 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.

15. A method of treating a wound, comprising:
-
positioning a wound dressing over a wound, the wound dressing comprising; a backing layer; and a plurality of flow channels beneath the backing layer extending radially from a central portion, wherein each of the plurality of flow channels defines a flow path that is separate along its length from the flow paths defined by each of the other of the plurality of flow channels and the plurality of flow channels are interconnected only at the center portion; and delivering oxygen to the wound through an inlet conduit positioned beneath the backing layer, the inlet conduit having an end portion under the backing layer in fluid communication with the central portion; wherein oxygen flows from the inlet conduit, through the central portion and along the plurality of flow channels to the wound. - View Dependent Claims (16, 17, 18)
