1. A renal replacement therapy system, comprising:
- a blood treatment device with at least one peristaltic pump mechanism;
a fluid circuit with respective portions to engage said at least one peristaltic pump mechanism;
said fluid circuit including separate engagement elements that may be brought together around said respective portions to engage said at least one peristaltic pump mechanism fluid circuit portions by a forcing a first of said engagement elements against a second of said engagement elements;
said fluid circuit and said blood treatment device being arranged such that multiple separate fluid flows may be maintained by an operation of said at least one peristaltic pump merely by means of said forcing, whereby an installation and set up of said fluid circuit is simplified.

Abstract
A first flow path is defined within a first panel that forms a part of an extracorporeal fluid circuit. A second flow path is defined within a second panel that also forms a part of the extracorporeal fluid circuit. The first and second panels are oriented in a fluid processing cartridge for mounting as an integrated unit on a fluid processing machine and for removal as an integrated unit from the fluid processing machine.

9. A method of performing renal replacement therapy using a blood treatment device with at least one peristaltic pump mechanism having separate engagement elements, a fluid circuit with respective portions to engage said at least one peristaltic pump mechanism, comprising the steps of:
-
locating said fluid circuit respective portions between said separate engagement portions;
attaching said engagement portions together to squeeze said respective portions therebetween;
operating a pump in one of said engagement portions to convey at least blood and at least one other fluid in order to perform a therapeutic treatment. - View Dependent Claims (10, 11, 12)

13. A renal replacement therapy system, comprising:
-
a blood treatment machine having at least one pump and at least one pump race configured to engage tubes of a fluid circuit;
a replaceable tubing set with tubes configured to engage with said at least one pump;
said at least one pump defining a single synchronous mechanical device such that said at least one pump, upon engaging with multiple ones of said tubes, said fluids are synchronously pumped through said tubes by an action of said at least one pump;
said tubes being engageable in a single step operation by placing them between said at least one pump and moving said at least one pump race toward said at least one pump. - View Dependent Claims (14, 15)
