    摘要: A device and method for increasing the safety of an extracorporeal blood treatment machine are based on monitoring transmembrane pressure. The transmembrane pressure measured by a measuring device during the treatment is compared with an upper limit transmembrane pressure L1 and a lower limit transmembrane pressure L2 which define a monitoring window. If the transmembrane pressure is outside this monitoring window, an alarm is triggered by an alarm device. The monitoring window is shifted as a function of the ultrafiltration rate. To determine the window limits, the transmembrane pressure is established after a change in the ultrafiltration rate is calculated. Thereafter, the window limits are determined on the basis of the expected transmembrane pressure.

    摘要: A method and device for determining the concentration of blood constituents, in particular haemoglobin, in a hose line of an extracorporeal blood circuit of an extracorporeal blood treatment apparatus, and an extracorporeal blood treatment apparatus with a device for determining the concentration of a blood constituent, are based on the correction of the influence of the blood flow rate of the blood flowing through the hose line on the determination of the concentration of the blood constituent. The device comprises a computing and evaluation unit configured such that a correction factor is ascertained for the influence of the blood flow rate on the determination of the concentration of the blood constituent. The concentration of the blood constituent is then determined based on a relationship describing the dependence of the concentration of the blood constituent on the intensity of the decoupled electromagnetic radiation, taking account of the correction factor.

    摘要: A device for determining the concentration of a constituent of blood in a hose line, in particular in the hose line of an extracorporeal blood circuit of an extracorporeal blood treatment apparatus, includes a clamping unit having an actuation mechanism configured to apply a clamping force such that first and second receiving elements are moved towards one another from a first position releasing the hose line into a second position clamping the hose line, in which the drive of the actuation mechanism takes place with an electric motor, and a monitoring unit configured to detect a hose line inserted into the receiving elements. A method for detecting a hose line in a clamping unit of a device for determining the concentration of a blood constituent in the hose line is also described. Automation of the measurement of the blood parameters is thus possible.

    摘要: A method for determining the recirculation in a fistula and/or the cardiopulmonary recirculation part during an extracorporeal blood treatment is disclosed, where the blood to be treated flows in an extracorporeal blood circuit through a blood chamber of a dialyzer split by a semi-permeable membrane into the blood chamber and a liquid chamber, and dialysis liquid flows in a dialysis liquid path through the dialysis liquid chamber of the dialyzer. A device for determining the recirculation in a fistula and/or the cardiopulmonary recirculation part, and a blood treatment device including such a device are also disclosed. The method and device are based on the fact that the sum of the fistula recirculation and the cardiopulmonary recirculation part, i.e. the total recirculation, is determined for two blood flow rates which differ from each other. The fistula recirculation and/or the cardiopulmonary recirculation part are then determined from the recirculation for the two blood flow rates.
