<p>An isolation enclosure is provided 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. The isolation enclosure comprises a frame adapted to surround the bed; and 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 large to allow a person located within the isolation chamber to be supported on the bed and to move freely within the isolation chamber. The canopy includes a base wall adapted to either (i) overly the mattress of the bed, and (ii) lie between the mattress and the frame of the bed. A frame transport device, such as wheels, casters, or sliders, is 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. An environmental control device is connectable in fluid communication with the isolation chamber and includes (i) a filter adapted to filter air entering and filter air exiting the isolation chamber, and (ii) a pump adapted to 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.</p> |
