DETAILED DESCRIPTION

(15) A first variant of the method is shown in steps in FIGS. 1 to 6. Multiple infusion bags 10 are fastened to a holding device 12. In the present case, the holding device 12 is packed with the sterilized infusion bags 10 in a tubular bag 20 as outer packaging. Instead of the tubular bag 20, a sealed bag or another bag could also be used, for example, as outer packaging. The outer packaging 20 is first of all disinfected on the outside and then moved into a clean room in which the further method steps are carried out by means of corresponding devices.

(16) According to FIG. 2, the tubular bag 20 is first of all cut open by an opening device 50 which is only shown schematically here. The cut 22 is effected, in this case, in the vicinity of the holding device 12 in order not to damage the infusion bags 10 inadvertently during the cutting operation. The severed part 24 of the outer packaging 20′ is then removed (FIG. 3).

(17) The opened outer packaging 20′ is then tipped up by a separating device 52, which is also only shown schematically, so that the open side 26 of the outer packaging 20′ points downward. As a result, the infusion bags 10 with the holding device 12 slip out of the opened outer packaging 20′(see FIG. 5). The empty outer packaging 20′ can then be disposed of whilst the holding device 12 with the infusion bags 10 can be processed further. As a rule, the holding device 12 with the infusion bags 10 fastened thereto is transferred from a positioning device 54 to a transport device 56.

(18) Instead of the tubular bag 20, a flat trough-like receptacle 30 can also be used for storing the infusion bags 10 which are fastened to the holding device 12 (see FIGS. 7 to 9). The trough-like receptacle 30 is closed by way of a sealed lidding film 32. After the decontamination of the outsides of the closed trough-like receptacle 30, the lidding film 32 can be removed in a clean room by an opening device 50.2, which is only shown schematically here (see FIGS. 8 and 9). In the present example case, the lidding film 32 is pulled completely off the trough-like receptacle 30. As an alternative to this, a flat opening could also be cut into the lidding film 32, through which the individual holding devices 12 with infusion bags 10 could be removed.

(19) As can be seen in FIG. 10, multiple holding devices 12 with infusion bags 10 fastened thereto can be stored and transported in a trough-like receptacle 30. The individual holding devices 12 (see also FIG. 11) are each provided, in this case, with multiple infusion bags 10, the infusion bags 10 being arranged overlapping one another in a fan-like manner. The infusion bags 10 are fastened to the holding device 12 via a hose attachment 14 in the present example case. The hose attachment 14 of each infusion bag 10 is clamped, in this case, in the holding device 12. In this case, the distances between two adjacent hose attachments 14 are identical in each case so that an exact alignment of the infusion bags 10 on the holding device 12 is provided. Said exact alignment of the infusion bags 10 enables the defined processing and transfer of the infusion bags 10, which have been separated into singles, to an arbitrary device for further processing 53 without manual alignment by operators being necessary.

(20) Multiple holding devices 12 lie slightly offset one above another inside the trough-like receptacle 30. Insofar as the side walls 34 of the trough-like receptacle 30 extend in a sufficiently flat manner, the removal of the individual holding devices 12 could be effected as a result of tipping up the opened trough-like receptacle 30′. As an alternative to this, the individual holding devices 12 could also be removed from the opened trough-like receptacle 30 by means of a gripping device as separating device 52.2. The individual holding devices 12 with the infusion bags 10 can then be processed further.

(21) Instead of the flat trough-like receptacle 30, a comparatively deep trough-like receptacle 40 could also be used for storing the holding device 12 with infusion bags 10 (see FIGS. 12 to 14). The individual holding devices 12 could be present in said trough-like receptacle 40 suspended in such a manner that the infusion bags 10 each hang downward (see FIG. 14). The trough-like receptacle 40 is closed with a sealed lidding film 42. After the decontamination of the outsides of the closed trough-like receptacle 40, the lidding film 42 can be removed in a clean room by an opening device which is not shown here (see FIGS. 13 and 14). In the present example case, the lidding film 42 is pulled completely off the trough-like receptacle 40. As an alternative to this, a flat opening could also be cut into the lidding film 42, through which the individual holding devices 12 with infusion bags 10 could be removed. Once the lidding film 42 has been removed, the individual holding devices 12 with the infusion bags 10 can be removed out of the opened trough-like receptacle 40′ by means of a gripping device which is not shown here. The individual holding devices 12 with the infusion bags 10 can then be processed further.
