摘要

The invention relates to a device for calculating blood flow and to an apparatus for extracorporeal blood treatment provided with the device (25). The device (25) includes a memory (26) for receiving and storing either a first datum (i1) relating to a blood flow removed from the patient (Qb), or a second datum (i2) relating to a flow of liquid (Qt) crossing a tract (13) of the extracorporeal circuit, and a third datum (3) relating to a flow of infusion liquid (Qinf) flowing through the infusion line. The device also comprises a control unit (27) able to calculate the first datum (1) or the second datum (i2) as a function of the third datum (i3) in relation to the flow of infusion liquid (Qinf).
