摘要:
A renal failure therapy machine includes a blood cleaning filter, a dialysis fluid circuit including a balance chamber, the balance chamber including a fresh dialysis fluid compartment configured to send fresh dialysis fluid to the blood cleaning filter and a used dialysis fluid compartment configured to receive used dialysis fluid from the blood cleaning filter, a fresh dialysis fluid line in fluid communication with the fresh dialysis fluid compartment of the balance chamber and the blood cleaning filter, and a flow restrictor in fluid communication with the blood cleaning filter, the flow restrictor configured to cause fresh dialysis fluid delivered from the fresh dialysis fluid compartment, through the fresh dialysis fluid line, to the blood cleaning filter to be pressurized so that a first amount of the fresh dialysis fluid performs convective clearance and a second amount of the fresh dialysis fluid performs diffusive clearance.
