Modular medical treatment replaceable component
View Patent ↗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 processing machine having a main unit and a door movably supported by the main unit such that the door can separate from the main unit to a loading configuration and come together with the main unit to an operating configuration; the main unit having actuators and pumps facing the door at least when in the operating configuration; the door having a control panel; a fluid circuit, engageable with the pumps and actuators, 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 support element supporting the blood and fluid lines in an arrangement that aligns respective portions of the fluid circuit with the pumps and actuators when said fluid circuit is engaged with said main unit and to maintain an alignment thereof when the blood processing machine is placed in said operating configuration; said main unit and said door being configured such that when said blood processing machine is placed in said operating configuration with said support element in said arrangement, said fluid circuit fluid circuit is located behind said control panel.
8. A system as in claim 7 , wherein said main unit includes a peristaltic pump actuator and said second part includes a pump race that is pressed against a portion of said fluid circuit when said blood processing machine is placed in said operating configuration.
9. A system as in claim 7 , wherein said main unit includes a peristaltic pump actuator and said second part includes a pump race that is pressed against a portion of said fluid circuit when said blood processing machine is placed in said operating configuration, said pump race being spring-relieved with respect to said second part.
10. A system as in claim 7 , wherein said main unit is latched against said second part with said fluid circuit between said first and second parts such that substantially all actuators required for a blood treatment operation are engaged thereby.
11. A system as in claim 7 , wherein said fluid circuit includes blood and treatment fluid lines which are pumped by said at least two pump races and/or pump actuators.
12. A system as in claim 7 , wherein said fluid circuit includes blood and replacement fluid lines.
13. A blood treatment system, comprising:
a blood processing machine having a fixed first part and a second, substantially smaller, part supported by and movably connected to the first part such that the first and second parts can separate to a loading configuration and come together to an operating configuration;
the first part having actuators and pumps facing the second part at least when in said operating configuration;
a fluid circuit, engageable with said blood processing machine, including blood lines connectable to a patient blood access and fluid lines connectable to a source of fluid used in performing a blood treatment;
at least one support element supporting said blood and fluid lines in an arrangement that aligns respective portions of said fluid circuit with said actuators and pumps when said fluid circuit is engaged with said blood processing machine and maintain an alignment thereof when said blood processing machine is placed in said operating configuration;
the second part having a control panel connected to control the pumps and actuators; said first part, second part and control panel being configured such that when said blood processing machine is placed in said operating configuration with said at least one support element in said arrangement, said fluid circuit fluid circuit is located between the first part and the control panel.
