Abstract
An improved fluidized bead bed (100) is reported. The bed (100) comprises an inflatable non-rigid bead diffuser (301) placed intermediate the beads (303) and the open tank (101) of the bed. An air porous bead impervious cover sheet (106) serving as a patient support surface covers the beads (303). When the diffuser (301) is inflated, the beads (303) are raised within the tank (101) beneath the cover sheet (106). Air escaping from the diffuser (301) fluidizes the beads (303). The exhausted fluidizing air passes through the patient support surface to aid in maintaining patient comfort. Control means (109, 110) regulate the operation of this device so as to maintain patient comfort and therapy. A method of use is also reported.
