  • Patent number: 4761841
    Abstract: A hospital gurney is provided which allows a single attendant to conveniently and safely transfer a patient between a hospital bed, examination table, or the like and the gurney while minimizing patient discomfort. The preferred structure includes a rollable gurney frame, a laterally shiftable patient conveyor, means coupling the patient conveyor with the gurney frame for lateral outward shifting of the conveyor relative thereto, and a laterally extendable plate coupled with the gurney frame below the level of the conveyor. In use, the gurney is placed next to a hospital bed, for example, the plate is extended outwardly to rest upon the bed surface, and the conveyor is shifted laterally outwardly onto the plate for supportive engagement therewith; the belting material included as part of the patient conveyor freely moves to allow one attendant to transfer the patient between the bed and the gurney.
