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.
Claims15
A blood processing system, comprising:
- an extracorporeal blood circuit configured to circulate blood through a blood treatment device, said extracorporeal blood circuit including a fluid circuit for conveying incoming and outgoing fluids related to a treatment operation of said blood treatment device;
- a blood treatment machine configured to control respective flows of said incoming and outgoing fluids to maintain a substantial equal volume of said incoming and outgoing fluids;
- said extracorporeal blood circuit including a first portion integrated, at least in part, within a first panel and a second portion integrated, at least in part, within a second panel, where said first and second portions carry said incoming and outgoing fluids;
- a fluid processing cartridge orienting the first and second panels for mounting as an integrated unit on said blood treatment machine and for removal as an integrated unit from said blood processing machine.
A blood processing system, comprising:
- an extracorporeal blood circuit configured to circulate blood through a blood treatment device and at least one other fluid related to a treatment operation of said blood treatment device;
- a blood treatment machine configured to control respective flows of said blood and said at least one other fluid;
- said extracorporeal blood circuit including a first portion integrated, at least in part, within a first panel and a second portion integrated, at least in part, within a second panel;
- a fluid processing cartridge orienting the first and second panels for mounting as an integrated unit on said blood treatment machine and for removal as an integrated unit from said blood processing machine.
A system as in 11, wherein said at least one other fluid includes incoming and outgoing fluids used by blood treatment device, each of said panels carrying a respective one of said incoming and outgoing fluids.
