Abstract
A carrying device for medical devices provides simple adjustment operation. The carrying device has a height-adjustable bracket (1) designed in the form of a parallelogram cranking mechanism with a self-locking pneumatic spring (13). A supply unit (21) for medical devices is arranged at one end of the bracket (1). A handle (22) with an electric release element (23) is arranged at the supply unit (21). A valve, which releases the blocking function, is opened within the pneumatic spring (13) during the actuation of the release element (23).
Claims3
A carrying device comprising:
- bracket legs arranged between a first end-side head piece and a second end-side head piece forming a parallelogram height-adjustable bracket;
- a self-locking pneumatic spring between one of said first end-side head piece and said second end-side head piece and one of said bracket legs, said self-locking pneumatic spring having a valve for abolishing a blocking function of said self-locking pneumatic spring;
- a ceiling bracket connected at said first head piece;
- a supply unit for medical devices connected at said second head piece;
- a handle at the supply unit for swiveling the bracket;
- an electric release element connected to the handle in one assembly unit;
- and
- a transmission means for actuating said valve, said transmission means being operatively connected between said electric release element and said valve, said transmission means comprising a pneumatic piston releasing said valve, a solenoid valve connected to a compressed gas source, said solenoid valve being opened by said release element and a compressed gas line between said pneumatic piston and said solenoid valve.
