Dialysis device for use with interface media, dialysis systems, use of dialysis device, method for establishing dialysis system, method for filling and/or priming dialysis system and method for removing air from dialysis system

A dialysis system comprising:

• an electrolyte solution;
• a first membrane comprising at least a first plurality of hollow fibers;
• a second membrane comprising at least a second plurality of hollow fibers;
• a first chamber formed by the first membrane, the first chamber being configured to receive a first fluid;
• a second chamber formed by the second membrane, the second chamber being configured to receive a second fluid;
• a third chamber formed in between a housing, the first membrane, and the second membrane, the third chamber being configured to receive the electrolyte solution;
• a dialysate regeneration device fluidly coupled to the second chamber, the dialysate regeneration device configured to regenerate the second fluid after the second fluid passes through the second chamber;
• a pump fluidly coupled to the third chamber, the pump configured to recirculate the electrolyte solution from an inlet port coupled with the housing at a first end of the third chamber to an outlet port coupled with the housing at a second end of the third chamber, wherein the second end is opposite the first end;
• and
• a blood detector fluidly coupled to the third chamber, the blood detector configured to detect a blood leak into the electrolyte solution,
• wherein a material and a structure of each fiber of the first plurality of hollow fibers are the same as those of the second plurality of hollow fibers.
