Problems solved by technology

[0005] The disadvantage of these known processing methods is that a sensor unit is required for each component
If necessary, a further sensor unit for measuring the conductivity of the mixed solution is used as an additional protection system, resulting in a relatively complex construction overall

Embodiment Construction

[0042] From figure 1A schematic time curve for the sum of the conductivities 100 can be seen in , that is to say the conductivity of a mixed solution of components A and B versus time. Furthermore, the time curves of the conductivity of components A and B are shown (LF (conductivity) component A, LF component B), so that the value of the conductivity of component B (shown in dotted line) is the same as that of component A The values ​​of the conductivities are added so that a temporally constant conductance sum of 100 is obtained.

[0043] The described embodiments relate to the measurement of electrical conductivity and are also conceivable for the measurement of any other parameter. The invention therefore also includes the measurement of any other conductivity-related or concentration-related parameters of the mixed solution, so that the concentration of components A and / or B or the substances they contain can be deduced.

[0044] From figure 1 As can be seen in , the pu...

Abstract

The invention relates to a method for preparing a medical solution from at least one liquid first component and at least one liquid second component, wherein the first component and the second component are each transported by means of a transport mechanism in order to obtain Mixed solution, wherein the conveying mechanism is operated in such a way that the concentration of the first component and the second component is modulated and the conductivity of the mixed solution or a parameter associated with the conductivity is measured at the measurement location, wherein the modulation of the concentration Conducted in a target state such that a specific modulation of the measured conductivity occurs or a specific modulation of a parameter associated with the conductivity occurs, or no modulation of the measured conductivity occurs or a parameter related to the conductivity occurs Modulation of associated parameters. The invention also relates to a device for preparing medical solutions and a blood therapy device with such a device.

Description

technical field [0001] The invention relates to a method and a device for preparing a medical solution from at least one liquid first component and at least one liquid second component, wherein the first component and the second component are each provided by means of at least one delivery mechanism to be transported in order to obtain at least one mixed solution. Background technique [0002] It is known from the prior art to prepare dialysis solutions from two components, one of which is an acidic concentrate and the other an alkaline concentrate. The concentrations of these two components must be monitored. In known devices this is done by providing, for each of the components, a conductivity sensor in conjunction with a temperature measurement to take into account the temperature dependence of the conductivity. [0003] The delivery of the components, that is to say the delivery of the concentrate, takes place by means of a concentrate pump. If the determined conducti...
