1. A blood treatment system, comprising:
- a blood treatment machine with first and second opposing portions spaced apart to form a gap therebetween;
said flow balancing machine having at least one actuator and at least one sensor disposed on at least said first opposing portion;
a support on attached to said blood treatment machine;
a cartridge panel holding a fluid circuit, said fluid circuit having at least one portion to be aligned with said at least one actuator and at least another portion to be aligned with said at least one sensor prior to engagement therebetween;
said support being configured to permit said cartridge panel to be rested thereupon when said cartridge panel is inserted in said gap;
said support and said cartridge panel being configured such that said fluid circuit at least one and at least another portions are aligned respectively with said at least on actuator and said at least one sensor;
said flow treatment machine first and second opposing portions being movable with respect to each other to close around said cartridge thereby to cause said at least one actuator to engage said at least one portion and said at least one sensor to engage said at least another portion.

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.

7. A blood treatment system, comprising:
-
a blood treatment machine with first and second opposing portions spaced apart to form a gap therebetween;
said flow balancing machine having actuators and sensors facing said gap and disposed on at least said first opposing portion;
a control panel located on one of said first and second portions;
a support on attached to said blood treatment machine, said cartridge panel to be rested thereupon when said cartridge panel is inserted in said gap;
a cartridge panel holding a fluid circuit, said fluid circuit having at least one portion to be aligned with said actuators and at least another portion to be aligned with said sensors such that when said cartridge panel is rested on said support, said sensors and actuators are so aligned;
said flow treatment machine first and second opposing portions being movable with respect to each other to close around said cartridge thereby to cause said actuators to engage said at least one portion and said sensors to engage said at least another portion.

13. A blood treatment system, comprising:
-
a blood treatment machine with first and second opposing portions spaced apart to form a gap therebetween;
said flow balancing machine having actuators and sensors facing said gap and disposed on at least said first opposing portion;
a control panel located on one of said first and second portions;
a support on attached to said blood treatment machine, said cartridge panel to be rested thereupon when said cartridge panel is inserted in said gap;
a cartridge panel holding a fluid circuit, said fluid circuit having at least one portion to be aligned with said actuators and at least another portion to be aligned with said sensors such that when said cartridge panel is rested on said support, said sensors and actuators are so aligned;
said flow treatment machine first and second opposing portions being movable with respect to each other to close around said cartridge thereby to cause said actuators to engage said at least one portion and said sensors to engage said at least another portion. said first and second opposing portions are movable in a single motion;
said fluid circuit at least one portion includes at least three tube portions configured to be engaged with peristaltic pumps;
said actuators include at least three peristaltic pumps;
whereby said tube portions and said peristaltic pumps are caused to be engaged by a movement of said first and second opposing portions.

14. A method of performing blood treatment using a blood treatment device having first and second portions that are brought together around a fluid circuit holder, comprising the steps of:
-
positioning a fluid circuit holder within a slot defined by said first and second portions'"'"' positioning said fluid circuit holder on a support of said blood treatment device;
said second step of positioning being effective to align components of said fluid circuit with corresponding actuators and sensors of said blood treatment machine;
closing said slot by mutually moving said first and second portions together;
said step of closing being effective to engage said fluid circuit components with said corresponding actuators and sensors of said blood treatment machine. - View Dependent Claims (15)
