    Abstract: The present invention relates to a method and a device for monitoring a blood treatment unit, subdivided by a semipermeable membrane into a blood chamber and a dialysis liquid chamber, of an extra-corporeal blood treatment device, which comprises an extra-corporeal blood circuit having an arterial branch leading to the blood chamber of the blood treatment unit, a venous branch, which extends away from the blood chamber, and a dialysis fluid system, in which the dialysis liquid chamber is arranged. The method according to the present invention and the device according to the present invention are based on the idea that the change of the flow resistance of the dialysis machine is determined based on two measurements, wherein an oscillating pressure signal in the extra-corporeal blood circuit or in the dialysis fluid system is measured before and after the change of the substitution rate and/or ultrafiltration rate, with which the substitute is applied to, or ultrafiltrate is removed from, the blood flowing in the blood circulation system. Preferably, the supply of substitute is interrupted temporarily.

    Abstract: The present invention relates to devices and methods for inspecting filters for extracorporeal blood treatment devices, e.g., filters for filtering dialysis fluid. The inspection of the filter according to the present invention is based on the measurement of the flow potential before and after changing the fluid flow of an electrolytic fluid between a transversal flow through the semi-permeable membrane of the filter and a longitudinal flow along the semi-permeable membrane of the filter, or vice versa. Changing the flow direction of the electrolytic fluid results in a change to the conductivity proceeding from a base value P to a higher value P2 or a lower value P1, wherein the conductivity readjusts to the base value P after a certain time interval T1, T2. An improper state of the filter is determined on the basis of the change in conductivity after changing the flow direction of the electrolytic fluid.

The pump flow includes a periodically non-altering direct component which is superimposed on a periodically altering alternating component. In order to monitor the regular operation of the hose pump, the alternating component of the power consumption in relation to the direct component of the power consumption is monitored as whether it increases and/or decreases during blood treatment.
