Problems solved by technology

[0009] Nevertheless, if this limit value of the fill volume is exceeded, for example due to leaks, this can lead to insufficient dissolution of the dry concentrate and thus to a concentration of the substance in the liquid concentrate in a relatively narrow outside the specified limit

Embodiment Construction

[0057] From figure 1 A flow diagram of a dialysis apparatus according to the invention is shown in . Reference numeral 10 denotes an RO water inflow portion from which water flows to a balance chamber system 20 .

[0058] The balance chamber system 20 comprises two parallel chambers K1 and K2, both of which have rigid outer wall portions, in which chambers extend respectively movable diaphragms which divide chambers K1 and K2 respectively into two areas, fresh water compartment F and old water compartment A.

[0059] In order to be able to use the balancing chamber system 20 to fill the dry concentrate container 100, after filling the hose system, by closing the valves V16 and V18 in the input lines of the two balancing chambers K1 and K2 will be present in the old water part of the balancing chamber The liquid volume in A is enclosed as a fixed swing volume. The swing volume thus comprises the volume of the waste water compartment A as well as the pipes extending therebetw...

Abstract

The present invention relates to a method for filling a container preferably containing at least one concentrate, wherein the concentrate is designed in such a way that, when dissolved or when mixed in / with a liquid, preferably water, it forms at least one liquid concentrate or part of a liquid concentrate that is suitable for producing at least one dialysis solution, and wherein the filling of the container takes place by means of the balance chamber system of a dialysis appliance, which has chambers from which the liquid is conveyed in repeating cycles into the container, wherein the pressure during one cycle of the filling phase of the container is measured, and wherein an alarm signal is emitted and / or the container-filling procedure is stopped if the measured maximum pressure in one cycle does not reach or does not exceed a limit value.

Description

technical field [0001] The invention relates to a method for filling a container which preferably contains at least one concentrate, wherein the concentrate is constituted such that it dissolves in a liquid or when it is diluted with a liquid, preferably in water or On dilution with water, at least one liquid concentrate or part of a liquid concentrate is formed, said liquid concentrate being suitable for the preparation of at least one dialysis solution, and wherein the container is filled by means of a balancing chamber system of a dialysis apparatus, said balancing chamber system There is a cavity from which the liquid is conveyed into the container in a repeated cycle. Background technique [0002] It is known from the prior art that dialysis solutions are prepared by means of dry concentrates. These dry concentrates contain, for example, various salts which are brought into solution with water. The concentrated solution prepared in this way is used, if necessary, with...
