Abstract

The present invention relates to a magazine having a plurality of solution bags for dialysis received therein, wherein the plurality of solution bags are identical; wherein the plurality of solution bags are fixed in a stationary manner in an identical orientation at different, but identically designed holding positions of the magazine; and wherein the holding positions are configured such that the solution bags can be removed from the magazine. The invention furthermore relates to a method of filling the solution bags.

First claim

The invention claimed is:

1. A magazine having a plurality of solution bags for dialysis received therein, wherein the plurality of solution bags are identical; wherein the plurality of solution bags are fixed in a stationary manner in an identical orientation at different, but identically designed holding positions of the magazine; and wherein the holding positions are configured such that the solution bags can be removed from the magazine, characterized in that the magazine has a plurality of identical carriers in which a respective one solution bag is fixed, with the carriers being stacked directly at one another, characterized in that the carriers have an areal base element and a framework extending in the normal direction, wherein the solution bag lies on the base element and is surrounded by the framework, and characterized in that the carriers have at least one pin that projects in the normal direction from the base element, with provision being made that the at least one pin is led through material sections of the solution bag to fix it in a stationary manner.

2. A magazine in accordance with claim 1 , characterized in that the solution bags are bags composed of connected and advantageously welded plastic films.

3. A magazine in accordance with claim 1 , characterized in that the solution bags have a material projection which is not in direct contact with the internal volume and in which at least one hole or a zone of weakened material is preferably worked, with the material projection preferably being a peripheral weld seam.

4. A magazine in accordance with claim 1 , characterized in that the solution bags are filled with a concentrate for preparing a dialysis solution.

5. A magazine in accordance with claim 4 , characterized in that the concentrate takes up less than 40% of the volume capacity of the bag.

6. A method of filling the solution bags of a magazine in accordance with claim 1 , wherein the magazine is inserted into a filling robot and individual solutions bags are then removed from the magazine and then filled or are filled and then removed from the magazine as part of an automated process.

7. A method in accordance with claim 6 , characterized in that the magazine is automatically introduced into a receiver of the filling robot so that the solution bags are present in a position suitable for the removal and, optionally, filling and so that the magazine is automatically removed from the receiver again after the removal.

8. A system comprising a magazine in accordance with claim 1 and a filling robot, wherein the filling robot comprises a receiver in which the magazine can be received in an exact fit.

9. A magazine having a plurality of solution bags for dialysis received therein, wherein the plurality of solution bags are identical; wherein the plurality of solution bags are fixed in a stationary manner in an identical orientation at different, but identically designed holding positions of the magazine; and wherein the holding positions are configured such that the solution bags can be removed from the magazine, characterized in that the magazine has a common frame having a plurality of slots at which the plurality of solution bags are placed, and characterized in that the frame has a perforated plate having a plurality of elongate holes and the solution bags each have a peg, wherein the elongate holes each have a slot, that is separated by holding projections, at an end of the elongate hole and have an extended portion at the other end or are open toward the margin of the perforated plate, and wherein the pegs have a collar whose diameters are larger than the width of the elongate hole, but smaller than the diameter of the extended portion.

10. A magazine in accordance with claim 9 , characterized in that the frame is releasably fastened to a box and is suspended at the upper edges of oppositely disposed side walls of the box.
