20120175295 | BLOOD TREATMENT UNIT FOR AN EXTRA-CORPOREAL BLOOD TREATMENT APPARATUS - 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. | 07-12-2012 |

20120330214 | DEVICE AND METHOD FOR MONITORING AN EXTRACORPOREAL BLOOD TREATMENT - A device and method for monitoring an access to a patient, an extracorporeal blood circuit and/or a dialysing fluid system includes a centrifugal pump for conveying blood or dialysing fluid instead of an occluding pump. Centrifugal pumps bring about a large change in flow rate by even a small change in pressure difference across the pump. The device includes a measuring unit for measuring the flow rate of blood or dialysing fluid conveyed by the centrifugal pump, and a control and computing unit configured to determine an incorrect vascular access or malfunction if a change in measured flow rate Q is more than a predetermined amount. For example, a small drop in pressure in the venous blood line leads to a marked increase in the flow rate of the centrifugal pump, which is used as a basis for the detection of an incorrect vascular access. | 12-27-2012 |
