Patent number: 11975131Abstract: A medical treatment system includes a disposable fluid circuit that includes a water inlet and a batch container arranged to hold a mixture, the mixture including water that is received from the water inlet and at least one concentrate. The fluid circuit also includes a drain line for draining fluid from the disposable fluid circuit, and a manifold with a plurality of fluid lines, the manifold connecting the water inlet, the batch container, a source of the at least one concentrate, and the drain line. A source of purified water supplies the purified water to the water inlet and a sensor detects a property of fluid in the disposable fluid circuit. A controller controls flowing of a first fluid followed by displacement by a second fluid causing the first fluid to flow to the sensor.Type: GrantFiled: December 23, 2020Date of Patent: May 7, 2024Assignee: NxStage Medical, Inc.Inventors: Jeffrey H.

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supply line having a proximal end into which peritoneal dialysis fluid is supplied and from which spend dialysate is withdrawn, and a distal end which is connected to a patient's peritoneal access.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.
