ABSTRACT:
An apparatus for periodically turning a patient from side to side in a bed includes a pull sheet portion having first and second lateral edges, with a plurality of first straps connected to the first edge, and a plurality of second straps connected to the second edge. These first and second straps each extend upwards to complementary strap spools supported on a longitudinal shaft over the patient and bed. A motor is adapted to rotate these strap spools in a selected direction to coil and retract one set of the straps, while uncoiling and extending the other set, so as to selectively raise one of the edges of the pull sheet while lowering the other, effectively turning the patient to one side or the other on the bed. A frame portion supports the longitudinal shaft, and an operator control box regulates and controls the motor.
