A device for providing at least one cleaning fluid, having a collecting container which by means of a pump and a fluid line is connected to a first cleaning container within which there is received a first cleaning component, further comprising a sensor unit and a control unit for controlling the pump and for interrupting a fluid loop depending on a concentration measured by the sensor unit in a contactless way.

The invention relates generally to a mixing system for mixing a dry material with a liquid. The mixing system includes a supply of dry material and a supply of liquid. An infinitely variable metering device meters the dry material into the liquid. A sensor senses the ratio of dry material to liquid. The sensor is operatively connected to the metering device to control the metering device to obtain a desired ratio of dry material to liquid. The dry material is dispensed volumetrically by volume of liquid to form the desired ratio of dry material to liquid.

An apparatus for premixing fluids to form dialysate for an extracorporeal blood treatment includes at least a first feed portion for supplying at least a first fluid from at least a first fluid reservoir, at least a second feed portion for supplying at least a second fluid from at least a second fluid reservoir, a premixing portion being configured to premix fluids supplied via the feed portions in counter flow to form a fluid mixture and at least one drain portion for draining the fluid mixture premixed in the premixing portion as dialysate. A method carries out appropriate steps. In a conductivity measurement along the drain portion the conductivity of the premixed fluid mixture is measured by means of a digital filter adapted to be parameterized based on at least two state variables of the premixing process at least in two phases with a first predictive phase and a second corrective phase.
