    摘要： A hemodialysis system configured to purge air from a blood circuit comprising: a dialyzer; a dialysis fluid circuit operable with the dialyzer via dialysis fluid inlet and outlet lines; the blood circuit operable with the dialyzer and including an arterial line, a venous line, a blood pump operable with the arterial line upstream of the dialyzer, and a physiologically acceptable fluid source in fluid communication with the arterial line upstream of the blood pump; and an air purging scheme wherein, with the dialysis fluid inlet and outlet lines connected to the dialyzer, air is purged using dialysis fluid or other physiologically acceptable fluid pumped by at least one of the fresh or used dialysis fluid pumps from the dialysis fluid circuit, through the dialyzer, into the blood circuit, in combination with dialysis fluid or other physiologically acceptable fluid from the source introduced directly into the blood circuit.

    摘要： A disposable cassette and system for dialysis are disclosed. An example disposable cassette includes a rigid portion, a fluid source inlet configured to be placed in fluid communication with a fluid source, and a fluid pumping receptacle placed in fluid communication with the fluid source inlet. The fluid pumping receptacle is configured to operate with a fluid pump actuator to pump fluid from the fluid source. The example disposable cassette also includes a dampening chamber formed as part of the rigid portion and in fluid communication with the fluid pumping receptacle. The dampening chamber is sized and arranged to reduce pressure fluctuations in the fluid delivered from the fluid pumping receptacle. The example disposable cassette further includes an outlet in fluid communication with the dampening chamber. The outlet provides dialysis fluid for a dialysis treatment.

    摘要： A system for dialysis is disclosed. An example peritoneal dialysis system includes a peritoneal dialysis machine including a pumping mechanism, and a sensor configured to measure a property of peritoneal dialysis fluid. The peritoneal dialysis system also includes a disposable cassette operable with the peritoneal dialysis machine. The disposable cassette includes a fluid source inlet for accepting fluid from a fluid source and a fluid flow path in fluid communication with the fluid source inlet. The fluid flow path includes a pump chamber operable with the pumping mechanism to pump fluid through the fluid flow path. The disposable cassette also includes a concentrate inlet for fluidly communicating concentrate to the fluid flow path, and a sensor chamber located along the fluid flow path and operable with the sensor. The sensor is configured to provide feedback to the peritoneal dialysis machine for mixing the concentrate for forming peritoneal dialysis fluid.
