Wound dressing

A wound interface device for use in negative pressure wound therapy, the device comprising:

• a flexible body having a plurality of projections configured to define a therapy space between a wound surface and a wound facing surface of the device body and to conform to the contours of various wound surfaces;
• and
• an outlet for the application of negative pressure and removal of fluids from the therapy space.
• wherein the projections define multiplicity of channels between the first and second ends of the device, the channels shaped to direct fluids laterally across the wound surface between the first and second ends.

A wound interface device for use in negative pressure wound therapy, the device comprising:

• a flexible body having a plurality of shaped protrusions each comprising a convex wound contacting surface configured to define a therapy space between a wound surface and a wound facing surface of the device body, the protrusions being shaped and distributed to prevent collapse of the spacers and/or of the therapy space under the application of negative pressure to the therapy space;
• an outlet for the application of negative pressure and removal of fluids from the therapy space;
• and
• a transverse outlet channel comprising a plurality of apertures to allow the ingress of fluids from the therapy space into the outlet channel.
