  • Circuit for connecting a protective conductor to at least two liquid-conveying lines and method for checking a protective conductor connection
    Patent number: 11413382
    Abstract: The invention relates to a circuit arrangement for a protective-conductor connection to at least two fluid-conducting lines 11, 12, in particular to at least two fluid-conducting lines which are guided outwards from the interior of a housing 1 of a medico-technical device, in particular the housing of a blood treatment device. The circuit arrangement comprises a plurality of protection apparatuses 16A, 16B; 17A, 17B 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 apparatuses 16A, 16B; 17A, 17B for electrical contacting are assigned to each fluid-conducting line 11, 12. As a result, two protective measures are taken for each fluid-conducting line.
