System and method for performing alternative and sequential blood and peritoneal dialysis modalities

A dialysis system comprising:

• a dialysis fluid pump receptacle actuated by a dialysis fluid pump actuator;
• a dialysis fluid line;
• a blood filter in fluid communication with the dialysis fluid pump receptacle via the dialysis fluid line;
• an extracorporeal circuit connectable to a patient;
• a blood pump receptacle actuated by a blood pump actuator, the blood pump receptacle in fluid communication with the blood filter via the extracorporeal circuit;
• and
• a control unit programmed to
• (i) in a first treatment create peritoneal dialysis fluid by combining purified water with a peritoneal dialysis concentrate, and
• (ii) in a second treatment create hemodialysis fluid by combining purified water with a hemodialysis concentrate.

A dialysis system comprising:

• a first dialysis fluid pump receptacle actuated by a first dialysis fluid pump actuator;
• a first dialysis fluid line;
• a second dialysis fluid pump receptacle actuated by a second dialysis fluid pump actuator;
• a second dialysis fluid line;
• a blood filter in fluid communication with the first dialysis fluid pump receptacle via the first dialysis fluid line and the second dialysis fluid pump receptacle via the second dialysis fluid line;
• an extracorporeal circuit connectable to a patient;
• a blood pump receptacle actuated by a blood pump actuator, the blood pump receptacle in fluid communication with the blood filter via the extracorporeal circuit;
• and
• a control unit programmed to
• (i) in a first treatment pump peritoneal dialysis fluid in a continuous flow manner through the first dialysis fluid pump receptacle, the first dialysis fluid line, the blood filter, the extracorporeal circuit, the blood pump receptacle, the patient's peritoneum, back through the blood filter, the second dialysis fluid line, and the second dialysis fluid pump receptacle by operating at least two of the first dialysis fluid pump actuator, the second dialysis fluid pump actuator and the blood pump actuator, and
• (ii) in a second treatment pump blood through the extracorporeal circuit, the blood pump receptacle and the blood filter to the patient by operating the blood pump.
