Abstract:
1. A device for motorized support of a patient positioning facility, the device comprising: a control facility, an electric motor drive that is operable to be controlled by a control signal of the control facility, a measurement device that is operable to record a setting of the electric motor drive and to generate an output signal representing the setting of the motor drive while the motor drive is stationary, a moveable patient bed, a bed drive that is operable to be driven by the electric motor drive and that is operable to displace the patient bed, and a position sensor that is operable to record the position of the patient bed and to generate an output signal representing the position of the bed, wherein position changes produced by the electric motor drive are characterized by a fixed assignment between the output signal of the position sensor representing the position of the bed and the output signal of the measurement device representing the setting of the motor drive, wherein the bed drive is flexible and/or elastic with respect to the displacement direction of the patient bed such that the output signal of the measurement device and the output signal of the position sensor are operable to be fed to the control facility, and wherein the control facility is operable to generate the control signal for the electric motor drive as a function of a change in the output signals with respect to one another such that a manual movement of the patient bed allowed by the flexible and/or elastic nature of the bed drive is detected by the position sensor while the motor drive is stationary, the control facility operable to initiate operation of the electric motor drive in response to the manual movement of the patient bed while the motor drive is stationary.
