Claim:
An isolation enclosure for isolating a person to an area about a bed, wherein the bed is adapted to support the person and includes a frame and a mattress overlying the frame, comprising: a frame adapted to surround the bed and support a canopy that overhangs the bed; a canopy connectable to the frame and defining an isolation chamber sealed with respect to the ambient atmosphere, the isolation chamber extends over the frame of the bed and is sufficiently sized to allow a person located within the isolation chamber to be supported on the bed and to move freely within the isolation chamber, wherein the canopy includes a base wall adapted to at least one of (i) overly the mattress of the bed, and (ii) lie between the mattress and the frame of the bed, the base wall defining an expanded portion that overlies a movable portion of the bed, and is movable with the movable portion of the bed to allow a person supported on the bed and within the isolation chamber to adjust the position of the bed; a frame transport device mounted on the frame and adapted to transport the frame and canopy in cooperation with the bed to thereby transport a patient supported on the bed and located within the isolation chamber; and an environmental control device connectable in fluid communication with the isolation chamber and including (i) a filter adapted to at least one of filter air entering and filter air exiting the isolation chamber, and (ii) a pump adapted to at least one of pump air into the isolation chamber to increase the pressure within the isolation chamber relative to the ambient atmosphere, and pump air out of the isolation chamber to decrease the pressure within the isolation chamber relative to the ambient atmosphere.
