Embodiment Construction

[0046] The various aspects of the invention will be described in connection with providing hemofiltration. That is because the features and advantages that arise due to the invention are well suited to the performance of hemofiltration. Still, it should be appreciated that the various aspects of the invention can be applied to achieve other blood processing objectives as well, such as hemodialysis and hemopheresis.

I. System for Providing Frequent Hemofiltration

[0047]FIG. 1 shows a system 10 that makes it possible for a person whose renal function is impaired or lacking, to receive convenient and therapeutically effective hemofiltration on a frequent basis, e.g., at least four times weekly and, preferably, six times weekly. The frequent hemofiltration therapy that the system 10 provides has as one of its objectives the maintenance of uremic toxin levels in the person's blood within a comfortable range, e.g., at no more than 80% of the maximum level. Through frequent hemofiltration,...

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.

Description

RELATED APPLICATIONS [0001] This application is a divisional of co-pending U.S. patent application Ser. No. 09 / 865,905, filed May 24, 2001, and entitled “Fluid precessing systems and methods using extracorporeal fluid flow panels oriented within a cartridge,” which is incorporated herein by reference.FIELD OF THE INVENTION [0002] This invention relates to systems and methods for processing blood, e.g., for filtration, pheresis, or other diagnostic or therapeutic purposes. BACKGROUND OF THE INVENTION [0003] There are many types of continuous and intermittent blood processing systems, each providing different therapeutic effects and demanding different processing criteria. [0004] For example, hemofiltration emulates normal kidney activities for an individual whose renal function is impaired or lacking. During hemofiltration, blood from the individual is conveyed in an extracorporeal path along a semipermeable membrane, across which a pressure difference (called transmembrane pressure)...
