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 patient support apparatus, such as the center. One or more object sensors may also be included in the patient support apparatus to assist in steering and/or navigating.

The camera may include one or more depth sensors that detect distances between the depth sensor and objects positioned within the field of view of the one or more cameras. A computer device processes the image signals and or depth signals from cameras and determines any one or more of the following: (a) whether a patient care protocol has been properly followed; (b) what condition a patient is in; (c) whether an infection control protocol has been properly followed; and (d) whether steps have been taken to reduce the risk of a patient from falling. Alerts may be issued if any conditions of importance are detected.
