The invention relates to a circuit arrangement for a protective-conductor connection to at least two fluid-conducting lines, in particular to at least two fluid-conducting lines which are guided outwards from the interior of a housingof a medico-technical device, in particular the housing of a blood treatment device. The circuit arrangement comprises a plurality of protection apparatusesA,B;A,B for electrical contacting which are designed such that an electrical connection to a fluid in the line can be produced using each protection apparatus for electrical contacting. In the circuit arrangement, at least two protection apparatusesA,B;A,B for electrical contacting are assigned to each fluid-conducting line. As a result, two protective measures are taken for each fluid-conducting line. In addition, the protection apparatusesA,B;A,B of one fluid-conducting lineare each electrically connected to another protection apparatusA,B;A,B of another fluid-conducting line. The protective-conductor concept according to the invention improves safety for the patient and makes it possible to test the protective-conductor connection in a simple manner.

Circuit for connecting a protective conductor to at least two liquid-conveying lines and method for checking a protective conductor connection

The present invention relates to a medical treatment arrangement having at least three device parts, with the first device part being a device part which is not made for the treatment of a patient, with the second device part being made in conjunction with the third device part such that a treatment of a patient can be made with them, with the second device part being made movable relative to the first device part and relative to the third device part, and with provision furthermore being made that the first device part and the second device part and/or the second device part and the third device part being made such that energy and/or data can be unidirectionally or bidirectionally exchanged between them.

Medical treatment arrangement

A roller pump includes a stator with a pump bed formed therein, and a rotor for acting on a hose inserted into the pump bed in arcuate form. The ends of the hose are guided out of the pump bed in a crossed configuration.

Pump with crossing lines

The invention relates to a roller pump consisting of a stator with a pump bed formed therein and a rotor for acting on a hose inserted into the pump bed in arcuate form. In accordance with the invention, the flow paths associated with the ends of the tube guided out of the pump bed cross.
