Wound cleansing apparatus with heat

An apparatus for treatment of a wound, comprising:

• a relatively liquid impermeable backing layer capable of forming a relatively fluid-tight seal or closure over a wound;
• a member comprising a flexible upper layer, a flexible lower layer, and a plurality of flow pathway arms, each flow pathway arm defining a flow path that is separate along its length from the flow paths defined by the other flow pathway arms, the member being positionable beneath the backing layer, wherein:
• the flow pathway arms are interconnected only at a center portion of the member;
• and
• the flow pathway arms each extend in a radial direction from the center portion of the member;
• and
• a conduit in fluid communication with the flow pathway arms having an end portion configured to be mounted above the center portion of the member and configured to extend away from the backing layer.

An apparatus for treatment of a wound, comprising:

• a relatively liquid impermeable backing layer capable of forming a relatively fluid-tight seal or closure over a wound, thereby forming a volume of space between the backing layer and the wound;
• a plurality of elongated fluid flow channels configured to be positioned beneath the backing layer, each elongated fluid flow channel defining a flow path that is separate along its length from the flow paths defined by the other elongated fluid flow channels, the fluid flow channels being formed between a flexible upper layer and a flexible lower layer;
• and
• a boss positionable on the upper layer within said volume of space;
• wherein:
• each of the plurality of elongated fluid flow channels extends in a radial direction away from the center portion of the plurality of elongated fluid flow channels;
• and
• the plurality of elongated fluid flow channels are interconnected only at a center portion of the plurality of elongated fluid flow channels.

A method of treating a wound, comprising:

• positioning a member comprising a plurality of flow channels over or within a wound, each flow channel defining a flow path that is separate along its length from the flow paths defined by the other flow channels, wherein the channels are interconnected only at a center portion of the member;
• and the channels each extend in a radial direction from the center portion of the member;
• positioning a relatively liquid impermeable backing layer over the member and the wound;
• forming a relatively fluid-tight seal or closure between the backing layer and healthy skin surrounding the wound;
• and
• forming a fluid flow path between the flow channels and a conduit having an end portion mounted above the center portion of the member;
• and
• drawing wound exudate away from the wound.
