Automatic patient turner

Abstract

This invention will alternately turn an immobile, bedridden patient 180 degrees. It is designed to prevent bedsores and the accumulation of fluid in the lungs. The device consists of five strategically placed inflatables on a flexible mattress assembly strapped to a hospital bed mattress. The knees are bent in a perpendicular, 90° position and sandwiched between a pair of inflated knee bags on top of the flexible mattress. The inflation of one of the elongated air bags beneath the flexible mattress raises that longitudinal side of the mattress to a 45° incline. This causes the knees to move from a 90° angle relative to the flat mattress an additional 45 degrees to a 135° angle. As those air bags deflate, the bent knees descend. Acting as a lever arm, the knees pull the body completely to the side of the turn, while a back support air bag pillow inflates.
