1. An appliance for administering reduced pressure treatment to a wound, the appliance comprising:

  • (a) an impermeable overlay comprised of a top end having an opening therein and a bottom end having an opening therein, wherein;

    (i) the bottom end is positioned over the wound on the tissue surrounding the wound so that the impermeable overlay encloses the wound and forms an approximately hermetic seal with such tissue; and

    (ii) the impermeable overlay is sufficiently rigid so that it supports a stopper and is supported out of contact with the wound;

    (b) a stopper having a port therein, the stopper being removably positioned in the top end opening of the impermeable overlay and forming an approximately hermetic seal with the top end opening of the impermeable overlay;

    (c) a suction drain comprised of a top drain portion positioned within the port in the stopper and a bottom drain portion extending from the top drain portion into the area of the wound under the impermeable overlay;

    (d) suction drain sealing means to seal the top drain portion to the port in the stopper; and

    (e) reduced pressure supply means to connect the top portion of the suction drain to a reduced pressure supply source that provides a supply of reduced pressure to the suction drain, so that the area under the impermeable overlay in the area of the wound is supplied with reduced pressure by the reduced pressure supply source.
