Drain and fill logic for automated peritoneal dialysis
First Claim
1. A system for performing a peritoneal dialysis therapy comprising:
- at least one dialysis fluid pump; and
a logic implementer including a central processing unit (“
CPU”
) and a pump controller operable with the CPU, the pump controller operable with the at least one dialysis fluid pump to perform a plurality of peritoneal dialysis cycles, the cycles including a fill phase, a dwell phase and a drain phase, the logic implementer configured to;
(i) store a continuous cycling peritoneal dialysis (“
CCPD”
) therapy having a total prescribed fresh dialysate fill volume delivered over n cycles during a total therapy duration; and
(ii) during the CCPD therapy after at least some dialysis fluid has been pumped by the at least one dialysis fluid pump, convert the CCPD therapy into a tidal peritoneal dialysis therapy having at least n+1 cycles and using the total prescribed fresh dialysate fill volume.

Abstract
A system for performing a peritoneal dialysis therapy includes at least one dialysis fluid pump, and a control unit operable with the at least one dialysis fluid pump to perform a plurality of peritoneal dialysis cycles, the cycles including a fill phase, a dwell phase and a drain phase. The control unit configured to (i) store a previously entered continuous cycling peritoneal dialysis (“CCPD”) therapy having a total prescribed fresh dialysate fill volume delivered over n cycles, the cycles performed over a total therapy duration, and (ii) automatically convert the CCPD therapy into a tidal peritoneal dialysis therapy having n+1 cycles, less a number of cycles already completed during the CCPD therapy, using the total prescribed fresh dialysis fill volume, and maintaining the total therapy duration.

8. A system for performing a peritoneal dialysis therapy comprising:
-
at least one dialysis fluid pump; an input device configured to receive information, including information regarding a continuous cycling peritoneal dialysis (“
CCPD”
) therapy for a patient; anda logic implementer including a central processing unit (“
CPU”
