Method and apparatus for purified pulse peritoneal dialysis using a single pump
First Claim
1. A system including only one pump for providing peritoneal dialysis to a patient comprising:
- a single catheter that is placed in the patient and is coupled to an end of a first fluid line of a single fluid circuit;
a source of dialysate that is coupled to an end of a second fluid line of the single fluid circuit;
a dialyzer that is in fluid communication with the first and second fluid lines and thereby with the source of dialysate and the catheter; and
a single pump positioned in the single fluid circuit between the source of dialysate and the single catheter and comprising the only means for pumping the dialysate from the source of dialysate into and out of the patient, through the dialyzer and back to the source of dialysate.

Abstract
The present invention provides an improved peritoneal dialysis method and system. The system comprises a single catheter that is placed in the patient, a source of dialysate, and a diatyzer in fluid communication with the source of dialysate and the catheter. The system includes a single fluid pump in fluid communication with the source of dialysate and the catheter. The single pump is capable of pumping the dialysate into and out of the patient and back to the source of dialysate. The method includes the steps of placing a single catheter in a peritoneum of the patient, providing a source of dialysate, coupling the source of dialysate in fluid communication with the catheter on a single fluid circuit, pumping the dialysate from the source of dialysate into and out of the peritoneum using a single pump in the single fluid circuit.

6. A method for dialyzing a patient comprising the steps of:
-
placing a single catheter in a peritoneum of the patient; providing a source of dialysate; coupling the source of dialysate in fluid communication with the catheter on a single fluid circuit, the dialysate passing from the source of dialysate through a dialyzer to be dialyzed before reaching the catheter; and pumping the dialysate in the single fluid circuit from the source of dialysate into and out of the peritoneum and through the dialyzer using a single pump. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13, 14)

15. A method for dialyzing a patient comprising the steps of:
-
placing a single catheter in a patient; coupling the catheter to a source of dialysate using a single fluid circuit; placing in the single fluid circuit a dialyzer; providing and positioning a single pump in the single fluid circuit to pump dialysate from the source of dialysate into and out of the patient; and causing the dialysate to flow through the dialyzer as it is pumped with the single pump into the patient from the source of dialysate; and
when it is pumped out of the patient to the source of dialysate. - View Dependent Claims (16, 17, 18, 19, 20)
