Patent Images
1. A disposable fluid circuit for use in a blood processing machine, comprising:
- a fluid circuit having tubular and flexible panel-shaped portions;
a support, said tubular and flexible panel-shaped portions being mounted in said support;
said tubular and flexible panel-shaped portions being adapted for conveying blood and at least one other fluid consumed by a blood treatment operation;
said support exposing at least some of said tubular and flexible panel-shaped portions on opposite sides of said support whereby opposing actuators and/or sensors of a blood treatment machine can engage them on opposing sides thereof;
said support panel-shaped portions being held in an overlying relationship by said support.

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.

10. A disposable fluid circuit for use in a blood processing machine, comprising:
-
a fluid circuit having flexible panel-shaped portions with flat walls that convey fluid between the flat walls; a support that holds the flexible panel-shaped portions, exposing at least one of the flexible panel-shaped portions to opposing actuators and/or sensors of a blood treatment machine which engages them; the panel-shaped portions being held in mutually-overlying relationship by the support such that the panel shaped portions overlap; the overlying panel-shaped portions being held in mutual engagement by the blood blood-processing machine and confined such that a flow in one of the panel-shaped portions applies a force to the other of the panel-shaped portions. - View Dependent Claims (11, 12, 13, 14)
