BLOOD TREATMENT SYSTEMS AND METHODS.

摘要

The present invention generally relates to hemodialysis and similar extracorporeal blood treatment systems. The subject matter of the present invention involves, in some cases, interrelated products. Alternative solutions to a particular problem. and/or a plurality of different uses of one or more systems and/or articles. Although the various systems and methods described herein are described in relation to hemodialysis, it should be understood that the various systems and method described herein are applicable to other dialysis systems and/or in any extracorporeal system able to treat blood or other bodily fluids, such as hemofiltration, hemodiafiltration. etc. In one aspect, the system includes four fluid paths: blood; inner dialysate; outer dialysate and dialysate mixing. In some embodiments, these four paths are combined in a single cassette. In other embodiments, these four paths are each in a respective cassette. In still other embodiments, two or more fluid paths are included on one cassette. In one embodiment, there is provided a hemodialysis system having at least two fluid paths integrated into: I) a blood flow pump cassette. 2) an inner dialysate cassette; 3) an outer dialysate cassette; and 4) a mixing cassette. The cassettes may be fluidly connected one to another. In some embodiments. one or more aspects of these cassettes can be combined into a single cassette.
