    摘要: The present invention relates to the field of regulating and presetting pump rates of blood pumps. It is directed at a device and a method in which the blood pressures are monitored upstream and/or downstream from the blood pump, and these values or another value formed from these values are compared with a limit value, which depends on an operating parameter or a pump parameter on the blood pump. In violation of the limit value, the pump rate of the blood pump is modified to such an extent or a new pump rate is determined so that the limit value is no longer violated or the degree of violation is reduced.

    摘要: The invention relates to a positive displacement pump 1 for conveying medical fluids, which pump has a pumping chamber 5 and a positive displacement element 15, and to a blood treatment apparatus comprising a positive displacement pump 1. In addition, the invention relates to a method for controlling a positive displacement pump 1 for conveying medical fluids. The positive displacement pump 1 according to the invention has an actuation member 20 in operative connection with the positive displacement element 20 for displacing or deforming the positive displacement element in order to convey the fluid into the pumping chamber or out of the pumping chamber, and a drive device 21 for displacing the actuation member 20. A control unit 14 is provided for to controlling the drive device 21 and an inlet valve 12 and outlet valve 13. The actuation member 20 is in operative connection with the positive displacement element 15 via a working chamber 19 that is filled with gas and has a sealed volume. In order to achieve a high conveying precision, the pressure in the working chamber 5 is kept constant when the positive displacement element 15 is moved.

    摘要: A device and method for monitoring an access to a patient, an extracorporeal blood circuit and/or a dialyzing fluid system includes a centrifugal pump for conveying blood or dialyzing 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 dialyzing 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.
