  • Patent number: 11723821
    Abstract: A patient support apparatus comprising a base movable about a floor surface and a deck comprising sections movable between deck configurations including an egress deck configuration. An articulation system coupled to the deck moves the sections. A lift mechanism moves the deck relative to the base between lift configurations including an egress lift configuration. An egress input is arranged for actuation by a user. A bed detection system monitors data associated with the patient support apparatus and communicates with a remote station. A controller interrupts communication of the bed detection system with the remote station, drives the articulation system to move the sections to the egress deck configuration, and drives the lift mechanism to move the support frame to the egress lift configuration in response to actuation of the egress input.

  • Publication number: 20230201049
    Abstract: Powered patient support apparatuses—such as beds, cots, stretchers, or the like—include a plurality of user controls that allow a caregiver to control the steering and/or driving of one or more powered wheels from multiple different locations around the patient support apparatus (e.g. head end, foot end, and/or the sides). The control is carried out by force sensors that detect both an orientation of the applied forces and a magnitude of the applied forces. Translational and/or rotational movement is effectuated, depending upon the magnitude and direction of the forces, as well as the physical location of the applied force relative to a reference point on the support apparatus, such as the center. One or more object sensors may also be included in the support apparatus to assist in steering and/or navigating.
