Abstract: For regulating and presetting the pump rate of a blood pump, a device and a method are configured for monitoring blood pressure values upstream and/or downstream from the blood pump. The monitored values, or another value formed from the monitored values, are compared with a limit value, which depends on an operating parameter or a pump parameter of 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, such that the limit value is no longer violated or the degree of violation is reduced.

Abstract: An apparatus for treating a medical fluid is provided which includes a treatment machine having a coupling surface, with a cassette made of a hard part having liquid-conducting passages which are covered by a flexible film being able to be coupled to the coupling surface of the treatment machine. A corresponding medical cassette is also provided. An air-free coupling of the flexible film of the cassette to the treatment machine is ensured in that air can be sucked out areally along a plane between the flexible film and the coupling surface during the coupling process and/or with a coupled cassette. A method for coupling the cassette and a method for checking the leaktightness of the cassette via the vacuum control of the air suction is also provided.
