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.

I claim: 1. A method of directly connected strip pulling for tensioning and of releasing said pulling for relaxing, the ends of a plurality of strips, wherein each one of said strips has two ends, for a bed whose support platform comprises of said plurality of strips grouped into a plurality of groups, wherein each one of said groups comprises a fractional number of said strips, with one end of each one of said plurality of strips fixedly connected to said bed, the method steps comprising:(a) attaching of the ends opposite to said fixed ends of the strips in a group, for each one of said groups, to a sturdy member, whereby the resultant number of said sturdy members is equal to the number of said groups,(b) attaching of each one of said sturdy members to a linear actuator,whereby the resultant number of said linear actuators is equal to the number of said groups,(c) connecting each one of said linear actuators to said bed,(d) operating said linear actuators in a cyclical manner wherein,(i) a fractional number of said linear actuators move the sturdy members connected to said fractional number of linear actuators and the strips connected to said sturdy members, in the direction that tensions said strips,(ii) the remainder fractional number of said linear actuators move the remainder sturdy members connected to said remainder fractional number of linear actuators and the remainder of strips connected to said remainder sturdy members, in the direction to relax said remainder of strips,(iii) said linear actuators alternate their to and fro movements in a programmed sequence,whereby, a person lying on said bed will be supported at any given moment by the fractional plurality of flexible strips that are in tension;wherein the linear actuator comprises a fluid cylinder utilized to tension and relax said plurality of strips: wherein the bed further comprises two pulleys as strip supports, one at each end of each strip of said plurality of strips;wherein said strip's ends are draped over each one of said pulleys to form a body support, for a body on said bed, by said strip when said strip is in tension;whereby, frictional resistance to the movement of said strip at said strip supports results in rotational movement of said pulleys, and thereby said rotational movement facilitates easier and quicker tensioning of said strip; the support platform further comprising a weight attached to the underside of each one of said strips, whereby upon relaxation of said strip, said weight will facilitate in the sagging of said strip.
