Abstract: A patient positioning device for manipulating mobility impaired patients. A specially dimensioned corset is adapted to be positioned around the torso of the patient and is coupled to two flexible straps which are individually routed to two drive assemblies designed for attachment on the vertically positionable safety side rails of the bed. A relay based control apparatus controlling the take up and play out of the straps to the two drives for regulating the movement of the corset and the patient.

Abstract: A patient positioning device for manipulating mobility impaired patients is disclosed. A specially dimensioned corset adapted to be positioned around the torso of the patient is coupled to a flexible strap which is routed via bed frame mounted guides to a drive assembly located beneath the bed's mattress. The flexible strap is of a length sufficient to permit it to extend from the corset and over the a conventional hospital bed protective side rails to the drive assembly.A variety of motors and drive systems are disclosed. One alternative features a reversible motor connected to a double roller mechanism. The strap is wound on a separate one of the rollers, so as the drive shaft rotates in one direction, one roller winds the strap upon itself while the other roller plays out a section of strap. Alternatively, a traveling block to which the strap is coupled pulls on one strap end while it feeds out the other.
