    摘要: 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.

    摘要: A method and device that identify impairments of the blood flow in an extra-corporeal blood circuit during extracorporeal treatment of the blood using an extracorporeal haemodialysis device, where the phase angle of at least one harmonic oscillation of an oscillating pressure signal that propagates in the extracorporeal blood circuit is determined. Impairments of the blood flow are detected in the extracorporeal blood circuit based on a characteristic modification of the phase angle of at least one harmonic oscillation of the pressure signal. A temporal modification of the phase angle may be compared with a predefined threshold value and an impairment is detected if the value of the modification of the phase angle is greater than the predefined threshold value. The method and device permit an early identification of a coagulation of the blood that flows through the haemodialysis unit, so that countermeasures can be initiated promptly.

    摘要: A method for determining a treatment parameter on a haemofiltration device, as well as a haemofiltration device for applying the method, based on the recognition that a determination method known from haemodialysis can, with little modification, be transferred to haemofiltration. To this effect a physical-chemical characteristic of the substitution fluid and of the fluid which is removed from the haemofilter by way of an ultrafiltrate outlet pipe, is determined. Furthermore, this characteristic is acquired before, after or during a change of this characteristic in the substitution fluid, and is evaluated. As a result, the ion dialysance and thus the urea clearance of a haemofiltration device, which can also be operated as a haemodiafiltration device, can be determined.
