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
A pump cassette comprising:
- a middle plate interposed between a first plate and a second plate, the middle plate having a first side facing the first plate and a second side facing the second plate;
- the first plate comprising a first actuation chamber wall of a first diaphragm valve;
- the second plate comprising a second actuation chamber wall of a second diaphragm valve;
- the cassette including an actuation chamber port for each of the first diaphragm valve and the second diaphragm valve, each said actuation chamber port extending away from a face of the cassette and configured for connection to separate conduits providing pneumatic pressure to the pump cassette;
- wherein the actuation chamber port for the first diaphragm valve connects to a first valve actuation chamber defined by the first diaphragm valve actuation chamber wall and a first valve diaphragm positioned between the first plate and the middle plate;
- and
- wherein the actuation chamber port for the second diaphragm valve connects to a second valve actuation chamber defined by the second diaphragm valve actuation chamber wall and a second valve diaphragm positioned between the second plate and the middle plate.

A pump cassette comprising:
- a middle plate interposed between a first plate and a second plate, the middle plate having a first side facing the first plate and a second side facing the second plate;
- the first plate comprising a pump actuation chamber wall of a diaphragm pump, and comprising a first valve actuation chamber wall of a first diaphragm valve;
- the second plate comprising a pumping chamber wall of the diaphragm pump opposite the pump actuation chamber wall of the first plate;
- the cassette including an actuation chamber port for the diaphragm pump and the first diaphragm valve, each said actuation chamber port extending away from a face of the cassette and configured for connection to separate conduits carrying pneumatic pressure to the pump cassette;
- wherein the actuation chamber port for the first diaphragm valve connects to a first valve actuation chamber defined by the first diaphragm valve actuation chamber wall and a first valve diaphragm positioned between the first plate and the middle plate;
- and
- wherein the actuation chamber port for the diaphragm pump connects to a pump actuation chamber defined by the pump actuation chamber wall of the diaphragm pump and a pump diaphragm positioned between the first plate and the middle plate.
