Abstract: The invention relates to a method and to a device for operating an electric peristaltic hose pump, in particular a hose pump for transporting fluids in medical-technical devices, in particular extracorporeal blood treatment devices. In order to monitor the regular operation of a hose pump, the power consumption of the pump or a physical variable in correlation with the power consumption, in particular the pump flow, is monitored. 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.

Abstract: The present invention relates to a method and a device for monitoring a fluid system of an extracorporeal blood treatment device. In the method according to the present invention and the device according to the present invention, the pressure in a ventilation line branching off the venous drip chamber in the venous blood line is measured, a hydrophobic filter being disposed in the ventilation line. A fault in the fluid system is determined in the absence of pressure variations in the segment of the ventilation line remote from the venous drip chamber. The pressure variations in the ventilation line can be generated downstream of the hydrophobic filter by alternately ventilating the ventilation line that is closed downstream of the hydrophobic filter during blood treatment.

Abstract: A device for the extracorporal blood treatment in a single-needle operating mode includes means for delivering blood into, and means for delivering blood out of means for collecting blood, and a controller for setting the respective delivery rates of the means for the delivery of blood. The operating mode of the means for delivering blood is continually switched between an arterial and a venous phase by the controller, wherein during the arterial phase the delivery rate Qb of the means for delivering blood is greater than the delivery rate Qsn of the means for delivering blood such that blood may be withdrawn from the patient during the arterial phase, and during the venous phase the delivery rate Qb is smaller than the delivery rate Qsn such that blood may be administered to the patient during the venous phase.

Abstract: The present invention relates to a method for regulating supply of substituate in an extracorporeal blood treatment with an extracorporeal blood treatment apparatus comprising a dialyzer divided by a semipermeable membrane into a blood chamber and a dialyzing fluid chamber and a device for supplying substituate. Moreover, the present invention relates to an extracorporeal blood treatment apparatus having a device for regulating supply of substituate. Regulation of supply of substituate in the extracorporeal blood treatment takes place as a function of the rheological loading of the dialyzer. To regulate supply of substituate during extracorporeal blood treatment, rheological loading of the dialyzer is determined from transmembrane pressure on the dialyzer and flow resistance of the dialyzer and substituate rate is increased or reduced according to the loading. The selection of dialyzer parameters or blood parameters is therefore no longer necessary and the distinction between pre-dilution and post-dilution is also made obsolete.

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.
