  • Patent number: 4939801
    Abstract: An improved patient transporting and turning gurney is disclosed for receiving and lifting a patient from a hospital bed, for transporting and depositing the patient on a hospital operating table, and for lifting and turning a patient for surgery. Preferably, the gurney has a U-shaped base, this base of sufficiently small dimension to fit under a hospital bed and of sufficiently large dimension to straddle the sides of a conventional operating table pedestal. The gurney further includes an overlying stretcher support, preferably U-shaped, for supporting a rotatable stretcher frame. A longitudinally extending rotating stretcher frame is mounted for rotation about its longitudinal axis on the stretcher support. Extending from the U-shaped base to the overlying stretcher support, there is provided a lifting device for moving the stretcher support upwardly and downwardly relative to the base.
