Abstract:
1. A reduced pressure treatment apparatus for administering reduced pressure to a wound site, the apparatus comprising: a drape for positioning over the wound site to create and maintain a substantially air-tight cavity between the wound site and the drape; a multi-lumen suction tube configured to be attached to a reduced pressure source, the multi-lumen suction tube having a center lumen and at least one outer lumen and being configured to deliver reduced pressure beneath the drape to the substantially air-tight cavity, the at least one outer lumen in fluid communication with the substantially air-tight cavity such that the reduced pressure is monitorable at the wound site through the at least one outer lumen; and wherein the multi-lumen suction tube is adapted to allow fluid to be drawn from the wound site through the center lumen, wherein the center lumen of the multi-lumen tube comprises a central bore adapted to remove fluids from the wound site and the at least one outer lumen comprises conduits located within the walls of the multi-lumen suction tube and adapted to allow air to flow there through, and wherein the conduits are circumferentially spaced at 90 degree intervals around the central bore.
