ABSTRACT:
An adjustable bed comprises a hospital bed frame chassis, an articulatable, multi-sectioned base platform mounted on the chassis, an adjustable patient support framework mounted on the base platform, and a patient support surface overlying the adjustable patient support framework and base platform. The adjustable patient support framework preferably includes two main parts: an adjustable torso support litter mounted on the articulatable torso-supporting section of the base platform; and an adjustable hip support litter mounted on the articulatable hip-supporting section of the base platform. Each of these support litters comprise a plurality of independently adjustable vertices or segments oriented at or near the periphery of the overlying patient support surface. Modulation of the patient support surface is accomplished through two conceptually distinct mechanisms—(1) articulation of the base platform and (2) movement of the vertices and/or segments of the adjustable patient support framework.
