The apparatus has a first means for carrying out a priming mode and a second means for carrying out an initial treatment mode. The first means is configured to control the preparation unit to prepare a flushing solution having a pH of &#x2265;7.3, with the extracorporeal circuit being filled with the flushing solution. The second means is configured to control the preparation unit to prepare the dialyzate having a pH of &#x2265;7.3, with the dialyzate circuit being filled with the dialyzate.

Blood treatment apparatus for reducing the probability of contact phase activation

An apparatus for extra-corporeal blood treatment and a method of presetting an initial mode of treatment in the opening phase of an extra-corporeal blood treatment are controlled based on the opening phase of a haemodiafiltration, in which particularly fast removal of electrolytes such as potassium or of urea occurs. The apparatus has a control and computing unit for presetting an initial mode of treatment, in which over a preset interval of time, substituate is fed to the extra-corporeal blood circuit, dialysis fluid is not fed through the dialyser and instead only ultrafiltrate is withdrawn from the dialyser and, on expiry of the preset interval of time, dialysis fluid is fed through the dialyser. Alternatively, dialysis fluid is provided during the preset interval of time through the dialyser at a dialysis fluid flow rate that is smaller than the dialysis fluid flow rate after the preset interval of time has elapsed.

The present invention relates to a method for controlling a blood treatment apparatus, with the conveying of blood using a blood pump, with the patient venous tubing clamp closed, until a predetermined volume of fluid has passed out of the blood tubing set through the membrane and into the dialysis fluid chamber. It also relates to a control and regulating apparatus and a treatment apparatus. It further relates to a computer program, a computer program product and a digital storage medium.

Method for controlling a blood treatment apparatus and apparatuses

The invention relates to a method and to a device for supplying a dialysis device with dialysate, and to a dialysis device comprising a device for supplying the dialysis device with dialysate. For producing dialysate, a containerfilled with a pulverulent dialysate concentrate K is provided, the amount of dialysate concentrate in the container being set in such a way that an amount of dialysate sufficient for a specified number of dialysis treatments can be produced using the dialysate concentrate. The method according to the invention and the device according to the invention make it possible to align the amount Kof concentrate in the containerand the planned consumption amount, which is dependent on the prescription from the doctor and the treatment parameters established by the machine. After the individual dialysis treatments have been carried out, it is continuously monitored whether the amount of concentrate is sufficient. It may be monitored whether the amount of concentrate is sufficient for the following treatment or for all treatments still to be carried out. If it is not sufficient, an alarm signal is generated. Otherwise, a control signal for initiating each of the next treatment cycles is generated.

Method and device for supplying dialysis liquid to a dialysis apparatus

The present invention relates to a double connector for a tubular insert intended to connect an extra-corporeal circuit to a peristaltic pump. The double connector comprises: a first channel with an axis a, a second channel with an axis anot parallel to a, a pressure chamber arranged along the first channel and suitable for co-operation with a pressure sensor. The pressure chamber is closed, on the opposite side with respect to the second channel, by a membrane which extends mainly in a plane &#x3c0; substantially parallel to both the axes aand a. Moreover, a straight line r, passing through both axes aand aand perpendicular thereto, crosses the membrane. The invention also relates to a tubular insert comprising the double connector and an extra-corporeal circuit comprising the tubular insert.

Tube for extra-corporeal circuit with double connector

An apparatus and method of determining the blood flow rate at which, in an extra-corporeal blood circuit of an extra-corporeal blood treatment apparatus, blood is pumped through the arterial blood line into the blood chamber of the dialyser and out of its blood chamber through the venous blood line is described. The method and apparatus provide for the determination of a plurality of parameters characteristic of the extra-corporeal blood treatment, with a given blood flow rate being determined in each case as a function of one of the characteristic parameters. A blood flow rate which is preset for the blood treatment is selected from the plurality of blood flow rates determined on the basis of the characteristic parameters. The blood flow rate to be preset is selected on the basis of a preset algorithm which may be implemented in software installed on a data processing unit or in hardware.
