    摘要： Dialyzers and methods are disclosed for performing shortened extracorporeal blood treatments. A flow restriction is provided in a dialyzer serving to partially impede flow of dialysate through the dialysate compartment of the dialyzer. As a result, the pressure of the dialysate upstream of the flow restriction is sufficient to cause the pressure profile of the dialysate from the dialysate inlet to the dialysate outlet of the dialyzer to be non-linear, in contrast to prior-art dialyzers. This perturbation of the dialysate pressure profile permits a single dialyzer to be used to remove large amounts of blood water from a patient's blood and re-infuse large amounts of liquid to the blood while still attaining a desired net ultrafiltration of the patient without the need for more than one dialyzer per treatment or for a separate replacement fluid.

    摘要： A number of improvements relating to methods and apparatuses for kidney dialysis are disclosed. These include checking of dialysate bypass status using flow measurement; using a flow sensor to confirm the absence of ultrafiltration during bypass; automatic testing of ultrafiltration function by removal of a discrete volume from a portion of the dialysate flow path coupled with a pressure test of that part of the flow path; using a touch screen user interface; bar graph profile programming of ultrafiltration, sodium, and bicarbonate parameters; using a RAM card to upload treatment instructions to, and to download treatment data from, the machine; automatic setting of proportioning mode (acetate or bicarbonate) based on connections of concentrate lines; predicting dialysate conductivity values based on brand and formulation of concentrates; minimizing no-flow dead time between dialysate pulses; initiating operation in a timed mode from a machine power-off condition; preserving machine mode during machine power-fail condition; calibration scheduling and reminding; automatic level adjusting; and blood leak flow rate detecting.
