    • The invention relates to a method for determining the volume of distribution of a blood component in the body of a living organism, especially the volume of distribution of urea, during an extracorporeal blood treatment. According to this method, the blood to be treated flows through the blood chamber (3) of a dialysis machine (1) in an extracorporeal circuit, said dialysis machine being divided into said blood chamber and a dialysing liquid chamber (4) by a semipermeable membrane (2). Dialysing liquid flows through the dialysing liquid chamber of the dialysis machine in a dialysing liquid channel. The method is based on the determination of the temporal change in the concentration of the blood component in the blood upstream of the dialysis machine using the temporal variation in a physical or chemical characteristic of the dialysing liquid upstream and downstream of the dialysis machine and the determination of the volume of distribution of the substance in the body of a living organism using the temporal variation in the concentration of the blood component in the blood. The invention also relates to a device for the extracorporeal blood treatment, comprising a device for determining the volume of distribution of a blood component in the body of a living organism.
    • 本发明涉及一种用于在体外血液处理期间确定生物体内的血液成分的分布体积,特别是尿素分布体积的方法。 根据这种方法,待处理的血液流过体外循环中的透析机(1)的血液室(3),所述透析机通过半透膜分成所述血液室和透析液室(4) 膜(2)。 透析液体在透析液通道中透过透析机的透析液室。 该方法基于使用透析机上游和下游的透析液的物理或化学特性的时间变化来确定透析机上游血液中血液成分浓度的时间变化,并确定 使用血液中血液成分的浓度的时间变化的物质在活体的体内的分布体积。 本发明还涉及用于体外血液处理的装置,其包括用于确定活体内体内血液成分的分布体积的装置。

    • A welding device has a beam source to generate electromagnetic beams for absorption in an object to be welded at a welding location, and at least one sensor situated to detect electromagnetic process beams generated during welding at the welding location. The sensor is to generate a sensor signal as a function of the detected process beams. The welding device also has a processing unit, which is connected to the sensor and the beam source, the processing unit being configured to control at least one parameter of the beam generation of the beam source as a function of the sensor signal. The welding device is to delimit by a window a beam bundle of the emitted process beams in a plane transverse to the beam propagation direction; in the plane, the window has a longitudinal dimension greater than a transversal dimension of the window perpendicular to the longitudinal dimension.
