Abstract
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.
