  • Patent number: 12097313
    Abstract: A peritoneal dialysis (“PD”) system includes a cycler including an actuation surface having a peristaltic pump actuator; at least one pair of capacitive sensing plates; a manifold assembly including a rigid manifold having at least one chamber, the rigid manifold configured and arranged to be abutted against the actuation surface for operation, wherein the at least one pair of capacitive sensing plates is positioned to be operable with the at least one chamber; a peristaltic pump tube; and a control unit configured to actuate the peristaltic pump actuator to pump dialysis fluid to the at least one chamber, receive a signal from the at least one pair of capacitive sensing plates, count a number of revolutions of the peristaltic pump actuator, determine a current volume per revolution for the peristaltic pump actuator, and use the current volume per revolution for a subsequent operation of the peristaltic pump actuator.

  • Patent number: 11911548
    Abstract: A peritoneal dialysis (“PD”) system includes a cycler including an actuation surface having a peristaltic pump actuator; a manifold assembly including a rigid manifold having first and second chambers (110a, 110b), the rigid manifold configured and arranged to be abutted against the actuation surface for operation, a peristaltic pump tube (124gh) extending from the first chamber (110a) to the second chamber (110b) of the rigid manifold, a dialysis fluid container line (124b) extending from the first chamber (110a), and a branch line (124c) extending between the dialysis fluid container line (124b) and the second chamber (110b); and a control unit configured to cause the peristaltic pump actuator to actuate the peristaltic pump tube (124gh) to pump dialysis fluid from the branch line (124c) into the second chamber (110b) and from the second chamber (110b) into the first chamber (110a).
