1. A blood treatment system, comprising:
- a blood treatment machine having a first opposing portion with a first surface and a second opposing portion with a second surface, the first and second opposing portions being spaced apart such that the first surface is parallel to the second surface with a gap formed therebetween, said first surface and said second surface being adjacent to the gap and facing each other;
said blood treatment machine having at least one actuator and at least one sensor disposed on at least said first opposing portion;
a support 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 one actuator and said at least one sensor;
said blood treatment machine first and second opposing portions being movable with respect to each other to close around said cartridge panel 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, said first and second surfaces remaining parallel to one another during movement of the first and second opposing portions.

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.

12. A blood treatment system, comprising:
-
a blood treatment machine with first and second opposing portions spaced apart to form a gap therebetween; the blood treatment machine having at least one actuator and at least one sensor disposed on at least the first opposing portion, the at least one actuator including at least one pump; a disposable cartridge panel that supports and holds a fluid circuit, the fluid circuit having at least one portion to be aligned with the at least one actuator and at least another portion to be aligned with the at least one sensor prior to engagement therebetween; a support attached to the blood treatment machine and configured to permit the cartridge panel to be rested thereupon when the cartridge panel is inserted in the gap; the support and the cartridge panel being configured such that the fluid circuit at least one and at least another portions are aligned respectively with the at least one actuator and the at least one sensor; the blood treatment machine first and second opposing portions being movable with respect to each other to close around the cartridge panel thereby to cause the at least one actuator to engage the at least one portion and the at least one sensor to engage the at least another portion, wherein said second opposing portion carries a user interface panel, and the first and second opposing portions are slidably interconnected. - View Dependent Claims (13, 15, 16, 17)
