Methods and apparatus for delivering peritoneal dialysis (pd) solution with a peristaltic pump

An apparatus for delivering peritoneal dialysis (PD) solution from a supply to a patient, comprising

• A. a first pump, in fluid coupling with the supply, that delivers PD solution from the supply to a mesne measuring element,
• B. the mesne measuring element including a chamber that is in fluid coupling with the first pump and that receives PD solution from the first pump, the mesne measuring element generating signals indicative of a volume of that received solution, and
• C. a second pump, fluidly coupled to the mesne measuring element, that routes PD solution from the mesne measuring element for delivery to the patient.

The apparatus of claim 11, wherein the mesne measuring element generates the volume-indicating signals based on a height of received PD solution in the chamber.

An apparatus for delivering peritoneal dialysis (PD) solution from a supply to a patient, comprising

• A. a first pump, in fluid coupling with the supply, that delivers PD solution from the supply to a mesne measuring element, the first pump generating first volume-indicating signals indicative of a volume of that delivered PD solution,
• B. the mesne measuring element including a chamber that is in fluid coupling with the first pump and that receives PD solution from the first pump, the mesne measuring element generating second volume-indicating signals indicative of a volume of that received solution, and
• C. a peristaltic pump, fluidly coupled to the mesne measuring element, that routes PD solution from the mesne measuring element for delivery to the patient.
