1. the system for extracorporeal blood treatment (1), described system has:

  • Blood filter device (2);

    Component (3), described component is used for blood to be pumped across described blood filter device;

    Citrate adds component (4), described citrate interpolation component is disposed on the direction of blood stream, the upstream of described blood filter device (2), and described citrate adds component and is configured to be added to by citrate in described blood;

    Calcium adds component (5), and described calcium interpolation component is disposed on the described direction of blood stream, the downstream of described blood filter device (2), and described calcium adds component and is configured to be added to by calcium in described blood;

    And control member (6), described control member is configured to start or stop using described citrate interpolation component (4) and/or described calcium interpolation component (5);

    The feature of described system isDescribed control member (6) is suitable for;

    -when blood treatment starts or before starting, start described citrate and add component (4);

    -after the described blood treatment of startup, determine the past of first time period (t1);

    AndCitrate described in-ongoing operation adds component (4), until blood treatment terminates, at this time point, described citrate of stopping using adds component (4), and wherein said control member (6) is further adapted for;

    -after described first time period has been pass by, when the overall outer blood volume in described system be filtered and by citrate process time, start described calcium add component (5);

    -during blood treatment, the described calcium that ongoing operation is in active state adds component (5), stably to maintain the calcium adding rate that user determines;

    And-after blood treatment terminates, the described calcium that ongoing operation is in active state adds component (5), until terminate the second time period (t2) in the past in described process.
