Abstract
Abstract A bed frame for prolonged care of invalids, which frame is constructed to relieve pressures on certain parts of the body to support the lumbar region and maintain alignment of the spinal column and legs and to allow air circulation to reduce or prevent ulcers. A pair of side frame members are curved vertically to conform to the shape of the back of the invalid. A pad of canvas and sheepskin is stretched between said members by lateral adjusting rods for adjusting the distance between the side frame members. Portions of the pad are cut-out to provide ventilation and reduce the chance of ulcers and patient discomfort.
