A specialized bed is described, (Figs 2 and 3), that will prevent bedsores, heal existing bedsores, with no repositioning of patient required. With modifications it will be an effective massager, (Figs 14 and 15). The following is a description for Bedsores Therapy. The electro-mechanically powered bed, designed for resting of a living body that has limited or no capability of motion by self, has its resting area composed of movable Bed Elements, (Figs 5 and 6). The sequential lowering of these Bed Elements from contact with the body for sufficient length of time reestablishes blood circulation near skin in the regions that had been starved of blood. Down and up motion of the Bed Elements is created by Gear Motor Drive 30 which rotates two Camshaft assemblies 28L and 28R. A series of Cams 82, arranged with gradual phase shift, give the down and up movements to the Bed Elements in a desired sequential and cyclical manner.
