摘要： A pumping device for feeding and metering liquids, in particular medical liquids, such as dialysis liquids, has a piston unit comprising a driving device and a piston, as well as a membrane unit comprising a membrane and a first chamber delimited by the membrane. The pumping device further has a hydraulic unit with a hydraulic fluid receiving chamber in communication with the piston of the piston unit and with the first chamber of the membrane unit. Metering reliability of such a pumping device is increased in that a regulating unit is provided to ensure a predeterminable metering speed and/or amount. A measurement device is also provided for directly determining the axial position of the piston of the piston unit and can be connected to the regulating unit.

摘要： The invention relates to a device for treating a medical fluid, said device comprising a treatment machine with a coupling surface, to which a cassette consisting of a hard part with fluid-conducting channels that are covered by a flexible film can be coupled. The invention also relates to a corresponding medical cassette. According to the invention, to guarantee that the film of the cassette can be coupled to the treatment machine without the inclusion of air, air can be sucked off along the plane lying between the flexible film and the coupling surface during the coupling process and/or when the cassette is coupled to the machine. The invention also relates to a method for coupling the cassette and to a method for checking the leak-tightness of the cassette by means of the regulation of the air removal by suction.

摘要： The invention relates to a valve for closing liquid channels, especially for using in disposable cartridges for extracorporeal circuits. Said valve (2) comprises a valve body having a pressure channel (4) and a seal bonnet (6) which can co-operate with the valve body in such a way that it closes the valve body side end of the pressure channel to the environment. The valve is embodied in such a way that a pressure chamber can be formed between the pressure channel and the seal bonnet, the seal bonnet comprising a deformable sealing region (8) for entering into a liquid channel (22) and closing the same. The invention also relates to an appliance for using with a disposable cartridge, comprising at least one liquid channel having an inventive valve or a receiving element for one such valve. The invention further relates to a disposable cartridge for using with an inventive appliance and a seal bonnet for using with an inventive valve.
