Abstract: A patient transport apparatus with a base, a litter comprising a support surface, and a lift mechanism to facilitate arranging the litter at different heights relative to the base between a plurality of lift configurations including a fully-retracted configuration and a fully-extended configuration. The lift mechanism includes an actuator including a cylinder, fluid reservoir, and a pump driven by a motor to direct hydraulic fluid from the fluid reservoir to the cylinder. A sensor outputs a signal indicative of a magnitude of pressure in the cylinder. A user interface with an input control is provided. A controller determines a target parameter for the motor and, in response to user engagement with the input control, drives the motor at the target parameter to effect movement of the litter relative to the base at a predetermined rate irrespective of a weight of a patient supported on the litter.

Abstract: A person support apparatus includes a deck with a seat section, a leg section, and a back section. The back section is pivotally mounted to the seat section. The leg section has a proximal end pivotally mounted to the seat section and a cantilevered end spaced a first distance from its proximal end. The seat section, the leg section, and the back section are arranged to lie in a common plane when the deck is in a supine configuration to support a person in a supine position. A lift is mounted to the seat section of the deck, with the lift being configured to raise the deck relative to a supporting floor surface to a maximum height less than the first distance.

Abstract: A patient handling apparatus includes a frame, a base, and a lift assembly supporting the frame relative to the base, the lift assembly configured to extend or contract to raise or lower the base or the frame with respect to the other of the base and the frame. The patient handling apparatus further includes a control system, which comprises at least one hydraulic cylinder to extend or contract the lift assembly, a hydraulic circuit to direct the flow of hydraulic fluid to and from the hydraulic cylinder, and a controller operable to control the hydraulic circuit.
