    摘要： A renal therapy system with cassette-based blood and dialysate pumping is disclosed. An example system includes a blood pump actuator, a dialysis fluid pump actuator, a dialysis fluid heater, a dialyzer, and a disposable unit. The example disposable unit includes a blood cassette portion configured to be operatively connected to the blood pump actuator to pump blood through the blood cassette portion. The example disposable unit also includes a dialysis fluid cassette portion, separate from the blood cassette portion, configured to be operatively connected to the dialysis fluid pump actuator to pump dialysis fluid through the dialysis fluid cassette portion. The blood cassette portion and the dialysis fluid cassette portion are both in fluid communication with the dialyzer. The example disposable unit also includes a heater bag configured to be placed in operable communication with the dialysis fluid heater and in fluid communication with the dialysis fluid cassette portion.

    摘要： A renal therapy apparatus includes a blood filter, a blood pump, a treatment fluid pump, and a control unit configured to control at least one of the blood pump or the treatment fluid pump during a filter cleaning sequence. The blood filter includes a plurality of hollow fiber membranes. During the filter cleaning sequence, a fluid mixture is formed by mixing air with a blood-compatible and physiologically safe fluid. Also during the filter cleaning sequence, the fluid mixture is transferred across insides and/or outsides of the plurality of hollow fiber membranes at least one time. The use of the fluid mixture enables the filter cleaning sequence to be performed during the blood treatment.

    摘要： A hemodiafiltration system with a disposable pumping unit is disclosed. An example system includes a medical fluid pump actuator, a medical fluid heater, a blood filter and a disposable unit. The example disposable unit includes a medical fluid cassette portion including a medical fluid cassette housing configured to be operatively connected to the medical fluid pump actuator to pump medical fluid through the medical fluid cassette portion when the medical fluid cassette portion is in fluid communication with a medical fluid source. The example medical fluid cassette portion is also configured to be placed in fluid communication with the blood filter and with an extracorporeal circuit communicating with the blood filter, the fluid communication enabling hemodiafiltration to be performed. The example disposable unit also includes a heater bag configured to be placed in operable communication with the medical fluid heater and in fluid communication with the medical fluid cassette portion.
