Patent ID: 7998125

Claim:
An appliance for administering reduced pressure treatment to an object or a portion of an object, the appliance comprising: a flexible chamber having an opening, wherein the flexible chamber is sized to enclose substantially all of the object or the portion of the object to be treated and adapted to maintain reduced pressure within the volume of the flexible chamber, wherein the chamber is a single chamber, said object or portion of the object extending through the opening into the volume defined by the flexible chamber; a collapsible frame, wherein the collapsible frame supports the flexible chamber away from the object or the portion of the object to be treated while the appliance is in use, and wherein the collapsible frame comprises one or more longitudinal frame members extending longitudinally along the length of the chamber and one or more circumferential frame members extending circumferentially across the chamber generally transverse to a longitudinal axis of the chamber, at least one of the one or more longitudinal members being movable between a collapsed configuration and an extended configuration, and wherein the longitudinal and circumferential frame members are inflatable and are in fluid communication with each other; a sealing mechanism to seal the opening so that reduced pressure may be maintained within the volume of the flexible chamber; and a reduced pressure supply mechanism to operably connect the flexible chamber to a reduced pressure supply source that provides a supply of reduced pressure to the flexible chamber, so that the volume within the flexible chamber is supplied with reduced pressure by the reduced pressure supply source in an amount sufficient to treat a wound, and wherein the chamber has a substantially uniform pressure throughout the volume defined by the flexible chamber; wherein the flexible chamber and the collapsible frame may be collapsed to a smaller size when the appliance is not in use.
