AUTOMATIC GRAVITY BED Russian patent published in 2013 - IPC A61F5/45 A61H1/02 

FIELD: medicine.

SUBSTANCE: invention refers to medical equipment and aims at using orthopaedics and traumatology for spinal extension in diseases and post-traumatic changes. The automatic gravity bed comprises a frame with a longitudinal bar and two hinged parallel-link motions with identical piece dimensions and with carriers placed on the longitudinal bar of the frame. Side rods of the hinged parallel-link motions are interconnected by a lumbar rest in the form of a corrugation with a low modulus of elasticity. Two shafts of adjoining crank arms of the hinged parallel-link motions comprise identical toothed wheels engaged into each other. Brackets with holes for placing an adjusting bar enabling both crank arms matched in the same plane when assembling are attached to the crank arms of the hinged parallel-link motions; the axes of said holes are parallel to the longitudinal axes of the crank arms. The bracket of one of the crank arms comprises a threaded hole wherein an adjustment screw ended with a spring end hole, seats; the second end of the spring is placed in a hole created in the bracket of the second crank arm. Each crank arm of the hinged parallel-link motions accommodates a fixed bed for placing a patient thereon.

EFFECT: higher load and pain management with substantial cost-cutting and simplification of the device and ease of use.
