Extracorporeal dialysis ready peritoneal dialysis machine
First Claim
1. A dialysis system comprising:
- a first membrane dialysate pump;
a second membrane dialysate pump;
a patient connector configured to be attached to a peritoneal patient port;
an extracorporeal circuit;
a blood pump in fluid communication with the extracorporeal circuit;
a blood filter in fluid communication with the extracorporeal circuit;
a control unit;
a memory device that stores a plurality of instructions which, when executed by the control unit, cause the control unit to selectively perform a therapy in which (i) at least one of the first and second membrane dialysate pumps is caused to pump dialysate to or from the patient connector to perform a peritoneal dialysis therapy or (ii) the blood pump is caused to pump blood to the blood filter and the dialysate pumps are caused to pump dialysate to the blood filter/extracorporeal circuit and remove used dialysate from the filter to perform a blood treatment therapy; and
a user interface operable with the control unit and the memory, the user interface including at least one of;
(i) an input device configured to enable a patient to select to perform the peritoneal dialysis therapy or the blood treatment therapy, or (ii) a message displayed to inform the patient which of the peritoneal dialysis therapy or the blood treatment therapy is to be performed.

Abstract
A dialysis system includes: (i) a dialysate pump; (ii) a patient line having a connector configured to be attached to a peritoneal patient part; (iii) an extracorporeal circuit; (iv) a blood pump in fluid communication with the extracorporeal circuit; (v) a blood filter in fluid communication with the extracorporeal circuit; and (vi) a control unit configured and arranged to selectively perform a therapy which (a) the blood pump is deactivated and the dialysate pump is caused to pump dialysate through the patient line or (b) the blood pump is activated to pump blood to the blood filter and the dialysate pump is caused to pump dialysate to the filter/extracorporeal circuit and/or remove fluid from the filter.

20. A dialysis system comprising:
-
At least one pump actuator positioned within a cassette interface for receiving either a peritoneal dialysis cassette or an extracorporeal blood treatment cassette; A control unit; A memory device; A user interface configured to operate with the control unit, the user interface configured to selectively display at least one parameter particular to a peritoneal dialysis treatment, and at least one parameter particular to an extracorporeal blood treatment; and Wherein the memory device stores a plurality of instructions which, when executed by the control unit, cause (i) the pump actuator to operate with a peritoneal dialysis cassette during a peritoneal dialysis treatment and (ii) the pump actuator to operate with an extracorporeal blood treatment cassette during an extracorporeal blood treatment. - View Dependent Claims (21, 22, 23, 24, 25, 26)

27. A dialysis system comprising:
-
A dialysate cycler configured to perform a peritoneal dialysis therapy; A blood pumping unit; A control unit; and A memory device that stores a plurality of instructions which, when executed by the control unit, cause the blood pumping unit to operate optionally with the dialysate cycler such that the cycler and blood pumping unit collectively perform a blood treatment therapy. - View Dependent Claims (28)

29. A dialysis system comprising:
-
a dialysate supply; a blood pump; a dialysate pump; a dialyzer; a control unit; and a memory device that stores a plurality of instructions which, when executed by the control unit, (i) cause the blood pump to pump blood through a blood portion of the dialyzer and the dialysate pump to pump from the dialysate supply through a dialysate portion of the dialyzer and (ii) perform hemodialysis the first time the dialysate is pumped from the dialysate supply through the dialyzer and hemofiltration the second time the dialysate is pumped from the dialysate supply through the dialyzer. - View Dependent Claims (30, 31, 32)
