Abstract: The present invention relates to a device for preparing a medical solution by mixing at least one liquid and at least one concentrate raw material, comprising a mixing container into which the at least one liquid and the at least one concentrate raw material can be fed, a control device, and a measuring device for measuring at least one parameter, preferably a density, of a mixture produced by means of the device during the mixing operation, and a corresponding method.

Abstract: The present invention relates to a device for preparing a dialysis concentrate or another fluid, wherein the device includes an inflow for the raw material for the dissolving of or mixing with a raw material located in a container that can be dissolved in the solvent or can be mixed with it and a container having a raw material to be dissolved by means of the solvent or miscible with the solvent, wherein the device has connection means for connecting to the container, characterized in that the device has a mixing unit that is self-regulating and a mixing line and a suction unit arranged in the mixing line and a mixing chamber, with the suction unit being able to be brought into fluid communication with the inflow for the solvent and, by means of a suction line, with the container connectable to the device, and with a return line downstream of the mixing chamber leading back to the container connectable to the device.

Abstract: The present invention relates to a device for preparing a dialysis concentrate, wherein the device has an inflow for the solvent and a receptacle for a raw concentrate substance to be dissolved by means of the solvent or miscible with the solvent and having a mixing container for mixing the solvent and the raw concentrate substance, wherein the device further has a controller that has a parameter unit that is configure to receive or determine at least one input parameter value, an optimization unit that is configured to determine an optimization of the mixing process based on the at least one input parameter value, and a control or regulation unit that is configured to control or regulate the preparation process of the device by means of one or more starting parameter values on the basis of the determined optimization.

Abstract: The invention relates to a device (10) for degassing dialysis concentrates for automatic density measurement in mixing systems, comprising: an overflowable filter element (53), wherein the overflowable filter element (53) converts gas bubble-laden dialysis concentrate at the input end into a gas bubble-free dialysis concentrate at the output end. The invention also relates to a mixing system (M) having a device (10) according to the invention and a method for degassing dialysis concentrates for automatic density measurement in mixing systems (M), comprising the steps: Introducing (100) the dialysis concentrate laden with gas bubbles into the overflowable filter element (53), Filtering out (200) gases, Diverting (300) the gas bubble-free dialysis concentrate, Measuring (400) the density of the gas bubble-free dialysis concentrate.

Abstract: The present invention relates to an apparatus for preparing a medical solution and preferably a dialysis concentrate solution that has a fluid system having a main circuit and a branch section in communication therewith, wherein the main circuit is a circuit in which a pump and a product container are arranged and in which liquid can be circulated by operating the pump; and wherein a raw material container can be connected in the branch section; wherein the branch section comprises a suction line that leads from the raw material container to be connected to a suction unit of the main circuit; wherein the suction unit is configured to suck in liquid together with raw material not yet dissolved from the suction line and to introduce it into a liquid flowing through the main circuit; and wherein a fine mixing chamber that has two connectors and one retention element arranged between the connectors for undissolved raw material is furthermore arranged between the suction unit and the product container.
