  • Patent number: 11583454
    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.

  • Patent number: 11410771
    Abstract: Patient care devices, including beds, cots, stretchers, recliners, chairs, thermal control systems, and IV poles, include a user interface for controlling an aspect of the patient care device, a port for communicating with an external device, and a control system. The control system determines when an external device is communicating with the port, what type of device the external device is, and if the patient care device includes software for allowing the user interface to act as a user interface of the external device. In some embodiments, the control system receives a device type identifier when an external device is coupled to the port, selects a software module for communicating with the coupled external device, and uses the selected software module for communicating with the coupled external device. Multiple external devices may be connected to the port and display data on a display of the patient care device.
