1. A composite wound dressing apparatus comprising:

  • a cover layer for defining a reservoir over a wound in which a negative pressure may be maintained by forming a substantially fluid-tight seal around the wound, the cover layer including an aperture therein through which fluids may be extracted from the reservoir;

    an elongate wick having a first end and a second end, the first end in fluid communication with the reservoir through the aperture in the cover layer, the second end disposed remotely with respect to the aperture in the cover layer, the elongate wick comprising a three-dimensional spacer fabric;

    a flexible wick cover extending over the elongate wick and having a first end and a second end, the first end of the wick cover configured for forming a substantially fluid tight seal over the aperture in the cover layer, the second end of the wick cover cover including an aperture therein through which fluids may be extracted from the elongate wick, the wick cover having an adhesive coating for establishing a substantially fluid tight seal over the aperture in the cover layer and with the skin surface disposed remotely from the wound; and

    a fluid port coupled to the wick cover and in fluid communication with the second end of the elongate wick through the aperture in the wick cover.
