First Claim
Patent Images
1. A blood treatment system, comprising:
- a blood processing machine having a slot with multiple actuators and sensors located within said slot;
a fluid circuit including blood lines connectable to a patient blood access and fluid lines connectable to a source of fluid used in performing a blood treatment;
a generally planar support element supporting said blood and fluid lines in a generally planar arrangement forming a cartridge;
said blood processing machine having at least one engagement element to engage said planar support element to position and orient it within said slot when said cartridge is placed in said slot;
said planar support element being configured to position and orient various portions of said fluid circuit such that they are in position to be engaged by said multiple actuators and sensor when said cartridge is placed within said slot.

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 processing machine having a slot with multiple actuators and sensors located within said slot;
a fluid circuit having fluid lines and used for performing a treatment on a patient;
a generally planar support element supporting fluid circuit in a generally planar arrangement forming a cartridge;
said fluid circuit includes at least one of containers, peristaltic pump headers, sensing stations, and valve stations;
said blood processing machine including equipment engageable with said at least one of said containers, peristaltic pump headers, sensing stations, and valve stations; and
said planar support element is configured to expose said at least one of said containers, peristaltic pump headers, sensing stations, and valve stations for engagement with said equipment on said fluid processing machine when said cartridge is inserted in said slot. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22)

23. A blood treatment system, comprising:
-
a blood processing machine having a slot;
said blood processing machine being configured such that said slot may be opened and closed;
said slot having spring-relieved engagement portions on at least one of first and second sides of said slot;
a fluid circuit including blood lines connectable to a patient blood access and fluid lines connectable to a source of fluid used in performing a blood treatment;
a generally planar support element supporting said blood and fluid lines in a generally planar arrangement forming a cartridge;
said planar support element being configured to position and orient various portions of said fluid circuit with respect to said spring-relieved portions such that when said cartridge is placed in said slot and said slot is closed, said spring relieved portions apply a pressure against said various portions of said fluid circuit. - View Dependent Claims (24, 25, 26, 27, 28, 29, 30, 31)
