    摘要： The invention relates to the balancing of fluid streams in a dialysis system. In particular the invention relates to a cassette for conveying a first and a second fluid stream in a dialysis system, wherein the first and the second fluid streams can be medical fluid streams such as for example dialysate streams or blood streams, wherein the cassette has a sensor as a device for balancing the first and the second fluid stream, and wherein the sensor has a first channel for the first fluid stream and a second channel for the second fluid stream. The invention further relates to a dialysis system, which is configured to accommodate at least one cassette which is configured as described above. Furthermore, the present invention relates to an arrangement by which two channels for the first and the second fluid streams are formed. In addition, the invention relates to a method for construction of the two channels or the arrangement.

    摘要： The present invention relates to a device and a method for monitoring a patient access, particularly for monitoring the venous vascular access in extracorporeal blood treatment where blood is withdrawn from the patient via a flexible arterial line which has an arterial needle or cannula, and provided to the patient via a flexible venous line which has a venous needle or cannula. The needle or cannula of the present invention is so designed that, due to the liquid flowing through the needle or cannula, air is drawn in if the needle or cannula is out of the vascular access, whereby sound is generated. A vascular access which is not in proper order is detected with great certainty and reliability by monitoring the surrounding environment for the occurrence of sound, particularly for the occurrence of the solid-borne sound which propagates along the flexible venous line of the extracorporeal blood circuit.

    摘要： The housing of the blood treatment unit according to the invention holds both a blood pump and a semi-permeable membrane. The blood pump is an impeller pump. The impeller of the impeller pump is surrounded by a partition which divides the housing into two chambers. The semi-permeable membrane forms at least a part of the partition. It is therefore possible for an exchange of matter to take place between the blood which flows through the first chamber of the housing and the dialysis fluid which flows through the second chamber of the housing. The blood treatment unit is intended for an extra-corporeal blood treatment apparatus and has a particularly compact construction.
