Definitions

  • the invention relates to a ceiling mounted supply unit and a method for operating the ceiling mounted supply unit, in particular, to a movable ceiling mounted supply unit and a method for operating the movable ceiling mounted supply unit.
  • Ceiling mounted supply units are installed in medical facilities in operating theaters and intensive care units for providing access to gases, electrical sockets and other utilities. Moreover, the ceiling mounted supply units comprise shelves or interfaces for medical devices to be positioned or attached. Therefore, ceiling mounted supply units themselves can be huge devices and, in particular, if they carry heavy accessories, moving of arms of the units involves a huge amount of force which can be difficult for the staff.
  • the object underlying the invention is to facilitate handling of the ceiling mounted supply units and to provide a ceiling mounted supply unit which assists in moving arms of the ceiling mounted supply units and assists in achieving end positions of the ceiling mounted supply units.
  • a ceiling mounted supply unit for providing medical apparatuses and/or gases and electric power in a room of a medical facility comprises a first swivel arm attached in a manner rotatable around the first vertical rotational axis to a ceiling of the room, a first drive configured to rotate the first swivel arm around the first vertical rotational axis, and a controller configured to control the first drive according to a motion request.
  • the provision of the drive for rotating the first swivel arm basically combined with the controller provides the option to assist actuation of the swivel arm in case of a large drag when moving the swivel arm. Furthermore, it provides the option for a manually controlled or for an automatically driven motion of the swivel arm.
  • a basic mobility of the ceiling mounted supply unit is provided, wherein, e.g., gas outlets and electrical sockets can be moved together with medical apparatuses installed on the supply unit. Therefore, lines for supplying the medical apparatuses can be set short in order to improve the hygienic circumstances although the medical apparatuses can be displaced for, e.g., a better access to a patient.
  • the provision of the medical apparatuses means that they are either arranged on a shelf of the ceiling mounted supply unit or that they are attached to the ceiling mounted supply unit, e.g., by means of a specific interface.
  • the ceiling mounted supply unit comprises a second swivel arm attached in a manner rotatable around a second vertical rotational axis to the first swivel arm, and a second drive controlled by the controller according to the motion request, wherein the second drive is configured to rotate the second swivel arm around the second vertical rotational axis.
  • the movability of the ceiling mounted supply unit is enhanced since not only a motion in a circle can be performed but any places within an area beneath an installation point of the ceiling mounted supply unit can be reached.
  • this movability is assisted or can be performed in a manually controlled or in an automatically driven mode.
  • the second swivel arm is attached in a manner rotatable around a horizontal rotational axis to the first swivel arm, and the ceiling mounted supply unit further comprises a third drive configured to rotate the second swivel arm around the horizontal rotational axis.
  • the movability of the ceiling mounted supply unit is enhanced since not only a horizontal motion but also a height adjustment is possible.
  • the ceiling mounted supply unit comprises a first torque sensor configured to detect a first torque exerted around the first vertical rotational axis to the first swivel arm and to transmit a signal related to the detected first torque to the controller as a component of the motion request.
  • the torque exerted to the first swivel arm e.g., initiated by manually moving the ceiling mounted supply unit, can be detected and the signal related to the detected first torque can be transmitted to the controller such that the detected torque can be understood as an intended motion of the first swivel arm and, therefore, it can be assisted by controlling the first drive in an appropriate manner.
  • the ceiling mounted supply unit comprises a second torque sensor configured to detect a second torque exerted around the second vertical rotational axis to the second swivel arm and to transmit a signal related to the detected second torque to the controller as a component of the motion request.
  • a started manual motion of the ceiling mounted supply unit in an arbitrary direction can be assisted by controlling the second drive in an appropriate manner and either by also controlling the first drive in an appropriate manner or by letting follow the first swivel arm the motion of the second swivel arm.
  • the ceiling mounted support system comprises a third torque sensor configured to detect a third torque exerted around the horizontal rotational axis to the second swivel arm and to transmit a signal related to the detected third torque to the controller as a component of the motion request.
  • a started manual motion of the ceiling mounted supply unit in a vertical direction can be assisted by controlling the third drive in an appropriate manner.
  • the ceiling mounted supply unit comprises at least one encoder assigned to one of each vertical rotational axis of the first swivel arm or of the first swivel arm and the second swivel arm or to the horizontal rotational axis of the second swivel arm, wherein the controller is configured to determine an absolute position of the first swivel arm or of the first swivel arm and the second swivel arm in the room based on the signals of the at least one encoder.
  • the controller is configured to store a predefined absolute position of the first swivel arm or of the first swivel arm and the second swivel arm
  • the ceiling mounted supply unit comprises a switching device configured to retrieve the stored predefined absolute position, wherein upon retrieve of the stored predefined absolute position as the motion request, the controller is configured to control the first drive, or the first drive and the second drive, or the first drive and the third drive, or the first drive and the second drive and the third drive in order to reach the stored predefined absolute position(s) of the first swivel arm or of the first swivel arm and the second swivel arm.

  • the controller is configured to determine a current absolute position of the supply component
  • the controller is configured to store a predefined absolute position of the supply component
  • the controller is configured to perform a path planning algorithm determining a determined path from a current determined absolute position of the supply component to the predefined absolute position of the supply component
  • the controller is configured to control the first drive, or the first drive and the second drive, or the first drive and the second drive and the third drive such that the supply component follows the determined path.
  • the absolute position of the supply component can be defined without defining the postures of the first arm and of the second arm which can facilitate and accelerate reaching of this absolute position. The reason is that if, e.g., the supply component is in a position close to the determined absolute position, a slight motion of one of the arms can be sufficient and a repositioning of both arms is not necessary.
  • a path optimized in view of consumed time and safety can be selected.
  • the ceiling mounted supply unit comprises a collision detection sensor configured to detect approach or contact of an obstacle to a face of the ceiling mounted supply unit, wherein the collision detection sensor is configured to transmit a signal related to the approach or the contact to the controller, and the controller is configured to notify the signal and/or to stop a motion of the ceiling mounted supply unit.

  • the method comprises the step of notifying a signal if a collision detection sensor detects approach or contact of an obstacle to a face of the ceiling mounted supply unit.
  • a method for operating the ceiling mounted supply unit comprises the steps: inputting a motion request to move a supply component for providing medical apparatuses and/or gas outlets and electrical sockets of the ceiling mounted supply unit into a predefined absolute position, performing a path planning algorithm determining a shortest possible path from a current detected absolute position of the supply component to the predefined absolute position of the supply component, and controlling the first drive, or the first drive and the second drive, or the first drive and the second drive and the third drive to rotate such that the supply component is on the determined path from the current detected absolute position of the supply component to the predefined absolute position of the supply component.
  • the supply component can be moved into the predefined absolute position on the path optimized in view of consumed time and safety.
