Claims22
A negative pressure wound therapy apparatus, comprising:
- a wound dressing comprising an elongate portion having a longitudinal axis and a bridging portion, wherein the bridging portion comprises a first end and a second end, wherein the bridging portion extends away from a middle portion of the elongate portion at a substantially right angle from the longitudinal axis at the first end of the bridging portion, the wound dressing comprising within both the elongate portion and the bridging portion:
- a wound contact layer configured to be positioned in contact with a wound;
- an absorbent layer and/or transmission layer over the wound contact layer;
- and
- a cover layer configured to cover and form a seal over the wound contact layer and the absorbent layer and/or transmission layer, wherein the cover layer comprises an aperture at a second end of the bridging portion;
- and
- a fluidic connector positioned over the aperture in the cover layer at the second end of the bridging portion.
