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.
Claims12
A pump cassette comprising:
- a primary membrane pump comprising a pumping chamber having an inlet fluidly connected to a first cassette inlet;
- a mixing chamber having an inlet fluidly connected to an outlet of the primary membrane pump, and an outlet fluidly connected to a cassette outlet;
- a first metering pump having an inlet fluidly connected to a second cassette inlet, and an outlet fluidly connected to the inlet of the primary membrane pump;
- and
- a second metering pump having an inlet fluidly connected to a third cassette inlet, and an outlet fluidly connected to the inlet of the mixing chamber, wherein
- a) the pumping chamber of the primary membrane pump is arranged to receive a first fluid via the first cassette inlet, and to receive a second fluid from the second cassette inlet, the second fluid being pumped by the first metering pump;
- b) the mixing chamber is arranged to receive a third fluid via the third cassette inlet, the third fluid being pumped by the second metering pump;
- and
- c) the pumping chamber of the primary membrane pump is configured to accommodate a pre-determined volume of the first fluid via the first cassette inlet and a pre-determined volume of the second fluid via the first metering pump, and the mixing chamber is configured to accommodate a pre-determined volume of the first and second fluids from the primary membrane pump and a pre-determined volume of the third fluid from the second metering pump, resulting in a mixing of said pre-determined volumes of the first, second and third fluids for delivery to the cassette outlet.
