In order to reduce the number of redundant sensors for measuring a property of process liquids in liquid-carrying production systems, there is proposed a measuring apparatus () for the online measurement of at least one property of process liquids at at least two different flow rates and during the production of a medical liquid, which measuring apparatus has a tank () for receiving the process liquid, a hollow accumulation vessel (), which is arranged within the tank (), in a side wall of the tank () or on a side wall of the tank () and through which the process liquid can flow depending on the filling level in the tank (), said accumulation vessel having at least one lower opening () and at least one upper opening () which are fluidically connected to the interior of the tank () such that process liquid can flow from the hollow accumulation vessel () into the tank, and a sensor () for measuring at least one property of the process liquid, which sensor is arranged in the hollow accumulation vessel ().

Measuring apparatus for the online measurement of at least one property of process liquids at at least two different flow rates for the production of a medical liquid

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.

Apparatus and method for preparing a medical solution

The invention relates to a device () for degassing dialysis concentrates for automatic density measurement in mixing systems, comprising: an overflowable filter element (), wherein the overflowable filter element () 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 () according to the invention and a method for degassing dialysis concentrates for automatic density measurement in mixing systems (M), comprising the steps: Introducing () the dialysis concentrate laden with gas bubbles into the overflowable filter element (), Filtering out () gases, Diverting () the gas bubble-free dialysis concentrate, Measuring () the density of the gas bubble-free dialysis concentrate.
