1. A device for creating a customized peritoneal dialysis solution and administering the customized peritoneal dialysis solution to a patient, the device comprising:
an input computing device configured for receiving health parameters of the patient to calculate a concentration of electrolytes for the customized peritoneal dialysis solution based in the patient health parameters
a unit housing connected to the input computing device;
a cassette housing disposed within the unit housing;
a cassette contained within the cassette housing;
at least one pump chamber formed within the cassette;
a plurality of inlet ports and outlet ports connected to the cassette, the inlet ports and outlet ports fluidly connected to the at least one pump chamber;
at least one valve for selectively sealing off and re-opening fluid communication between any one or more of the inlet ports and the at least one pump chamber and the outlet ports and the at least one pump chamber;
a first bag containing a dextrose solution connected by a first fluid line to a first inlet port to the pump chamber;
a second bae containing an electrolyte solution connected by a second fluid line to a second inlet port to the pump chamber;
a third bae containing a buffer solution connected by a third fluid line to a third inlet port to the pump chamber;
a water purifier connected to a tap water source and configured for providing sterile water from the tap water source through a water line connected to the cassette;
wherein the at least one pump chamber within the cassette is configured to selectively withdraw and measure a volume of dextrose solution from the first bag, a volume of electrolyte solution from the second bae, a volume of buffer solution from the third bae for mixing with water within the pump chamber to create the customized peritoneal dialysis solution based on the health parameters received by the input computing device and deliver the customized peritoneal dialysis solution to a receptacle fluidly connected to the pump chamber prior to administration to the patient.
