Patent number: 11690941Abstract: A method of performing a dialysis treatment includes using a pump and a dialysate supply line to transport peritoneal dialysis fluid, the supply line having a proximal end into which peritoneal dialysis fluid is supplied and from which spend dialysate is withdrawn, and a distal end which is connected to a patient's peritoneal access. The method further includes generating proximal and distal pressure signals using pressure detectors located at both the proximal and distal ends, respectively, of said supply line. During a drain cycle in which spent dialysate is pumped from the patient, the method includes, responsively to the proximal and distal pressure signals, detecting a characteristic of a pressure difference between the distal and proximal ends whose magnitude is determined by a predicted change in dialysate properties, and responsively to the characteristic, generating a signal indicating the change in dialysate properties.Type: GrantFiled: March 21, 2019Date of Patent: July 4, 2023Assignee: NxStage Medical, Inc.Inventors: Jeffrey H. Burbank, James M. Brugger, Dennis M. Treu, Mark T. Wyeth
