Claim Text:
1. A dialysis supply system comprising: a plurality of dialysis treatment units; a central dialysis liquid manufacturing unit that can be coupled via at least a first conduit to the plurality of dialysis treatment units; at least one filter comprising a first region coupled to the central dialysis liquid manufacturing unit and a second region coupled to at least one of the dialysis treatment units, the first region of the filter being separated from the second region of the filter by a membrane; a plurality of disposable, single-use hydraulic modules configured to be connected to the plurality of dialysis treatment units and operable with the plurality of dialysis treatment units to exclusively conduct dialysis liquid through the dialysis treatment units; a plurality of disposable, single-use blood modules configured to be connected to the plurality of dialysis treatment units and operable with the plurality of dialysis treatment units to conduct blood through the dialysis treatment units; a first valve arranged in a first fluid-conducting line coupled to the first region of the filter and to the first conduit; a second valve arranged in a second fluid-conducting line coupled to the first region of the filter and to the first conduit; and a third valve arranged in a third fluid-conducting line coupled to the second region of the filter and to a hydraulic module of the plurality of hydraulic modules, wherein, in a first mode, a control unit operates the first, second, and third valves to transport liquid from the central dialysis liquid manufacturing unit through the first and second regions of the filter to the hydraulic module, and, in a second mode, the control unit operates the valves to transport liquid to at least one of the first and second regions of the filter without transporting liquid from the central dialysis liquid manufacturing unit to the hydraulic module, and wherein, in the second mode, the control unit operates the first, second, and third valves such that the first valve is closed, the second valve is open, and the third valve is closed.
