Abstract
In one aspect, the invention provides methods and apparatus for delivering peritoneal dialysis (PD) solution (or other fluids), from a supply to a patient. A first pump, in fluid coupling with the supply, delivers PD solution from the supply to a 'mesne' (or intermediate) measuring element, and generates signals indicative of a volume of that delivered PD solution. The mesne measuring element, in fluid coupling with the first pump, generates signals indicative of a volume of PD solution received from that pump. A second pump, fluidly coupled to the mesne measuring element, routes PD solution from the mesne measuring element for delivery to the patient.
