Abstract
A cassette integrated system. The cassette integrated system includes a mixing cassette, a balancing cassette, a middle cassette fluidly connected to the mixing cassette and the balancing cassette and at least one pod. The mixing cassette is fluidly connected to the middle cassette by at least one fluid line and the middle cassette is fluidly connected to the balancing cassette by at least one fluid line. The at least one pod is connected to at least two of the cassettes wherein the pod is located in an area between the cassettes.
Claims20
An integrated cassette assembly of a dialysis system comprising:
- a first cassette, a second cassette, and a third cassette, wherein the second cassette is interposed between the first cassette and the third cassette;
- a plurality of pod housings positioned between the second cassette and the third cassette, and between the second cassette and the first cassette, each pod housing having a fluid connection to each of the cassettes between which the pod housing is located;
- a plurality of valves in each cassette, each said valve having a fluid connection to a respective pod housing or to a fluid inlet or outlet of the cassette assembly;
- and
- at least one metering pump in the first cassette, the metering pump having a fluid connection to an inlet of the cassette assembly for connection to a dialysate solution supply when the dialysis system is in operation and a fluid connection to a mixing flowpath in the cassette assembly;
- and
- at least one ultrafiltration pump in the third cassette, the ultrafiltration pump having a fluid connection to an inlet and to an outlet of the cassette assembly.
