Description

TECHNISCHES GEBIETTECHNICAL AREA

Die Erfindung betrifft ein Verfahren, bei dem leere Infusionsbeutel, die in der Regel sterilisiert angeliefert werden, entpackt und vereinzelt werden können. Anschließend können die Infusionsbeutel einer weiterverarbeitenden Vorrichtung zugeführt werden, beispielsweise um die Infusionsbeutel mit einer Flüssigkeit zu befüllen.The invention relates to a method in which empty infusion bags, which are usually delivered sterilized, can be unpacked and separated. The infusion bags can then be fed to a further processing device, for example in order to fill the infusion bags with a liquid.

Bei den Infusionsbeuteln kann es sich um Beutel mit lediglich einer Kammer handeln, aber auch um Mehrkammerbeutel. Mehrkammerbeutel können beispielsweise auch ein Pulver und eine Liquidkammer umfassen.The infusion bags can be bags with only one chamber, but also multi-chamber bags. Multi-chamber bags can for example also comprise a powder and a liquid chamber.

STAND DER TECHNIKSTATE OF THE ART

Die Zuführung und das Entpacken von sterilen Infusionsbeuteln wird üblicherweise durch manuelle Arbeitsschritte realisiert. Die sterilen Infusionsbeutel werden in einer Umverpackung angeliefert. Die Umverpackung mit den Infusionsbeuteln wird desinfiziert und in einen ersten Bearbeitungsraum, der mit Handschuheingriffen ausgestattet ist, überführt. In diesem ersten Bearbeitungsraum wird die Umverpackung von einem Bediener manuell geöffnet und die einzelnen Infusionsbeutel werden der Umverpackung entnommen. Mehrere Infusionsbeutel werden in einem Übergabe-Tray platziert und erneut desinfiziert, bevor das Übergabe-Tray mitsamt der Infusionsbeutel in einen zweiten Bearbeitungsraum überführt wird. Auch in diesem zweiten Bearbeitungsraum erfolgt die Weiterverarbeitung manuell durch einen Bediener, der mittels Handschuheingriffen agieren muss. Die Infusionsbeutel werden durch den Bediener zunächst vereinzelt. Da die Infusionsbeutel häufig mittels Vakuum innerhalb der Umverpackung positioniert werden, kann dieses Vereinzeln eine gewisse Zeit in Anspruch nehmen, da die Infusionsbeutel aneinander anhaften können. Die vereinzelten Infusionsbeutel werden in einen dritten Bearbeitungsraum, der ebenfalls mit Handschuheingriffen ausgestattet ist, überführt. In diesem Bearbeitungsraum werden die einzelnen Infusionsbeutel von einem weiteren Bediener in einer definierten Ausrichtung angeordnet und an die weiterverarbeitende Vorrichtung übergeben. Beispielsweise können die einzelnen Infusionsbeutel in die Transportfächer eines Transportbandes eingelegt werden. Alternativ dazu können die Infusionsbeutel auch an Transportzangen aufgehängt werden.The feeding and unpacking of sterile infusion bags is usually carried out by manual work steps. The sterile infusion bags are delivered in an outer packaging. The outer packaging with the infusion bags is disinfected and transferred to a first processing room, which is equipped with glove openings. In this first processing room, the outer packaging is opened manually by an operator and the individual infusion bags are removed from the outer packaging. Several infusion bags are placed in a transfer tray and disinfected again before the transfer tray and the infusion bag are transferred to a second processing room. In this second processing room, too, further processing is carried out manually by an operator who has to act with gloves. The infusion bags are first separated by the operator. As the IV bag often are positioned within the outer packaging by means of a vacuum, this separation can take a certain amount of time, since the infusion bags can stick to one another. The separated infusion bags are transferred to a third processing room, which is also equipped with glove openings. In this processing room, the individual infusion bags are arranged in a defined orientation by a further operator and transferred to the device for further processing. For example, the individual infusion bags can be placed in the transport compartments of a conveyor belt. Alternatively, the infusion bags can also be hung on transport tongs.

Dieses stufenweise Entpacken durch Bediener in Handschuheingriffen wird zunehmend kritisch gesehen. Für die Bediener ist die Arbeit mit Handschuheingriffen körperlich beschwerlich, so dass es verhältnismäßig schnell zu Ermüdungserscheinungen kommt. Auch die Aufrechterhaltung der Sterilität wird zunehmend kritisch betrachtet, da eine nachträgliche Kontamination der offenen Innenseite der Umverpackung oder auch der Infusionsbeutel nicht sicher ausgeschlossen werden kann.This step-by-step unpacking by operators in glove openings is viewed increasingly critically. For the operator, the work with gloves is physically arduous, so that symptoms of fatigue occur relatively quickly. Maintaining sterility is also being viewed increasingly critically, since subsequent contamination of the open inside of the outer packaging or the infusion bag cannot be reliably ruled out.

DARSTELLUNG DER ERFINDUNGDISCLOSURE OF THE INVENTION

Ausgehend von diesem vorbekannten Stand der Technik liegt der Erfindung die Aufgabe zugrunde, ein verbessertes Verfahren zum Entpacken und Vereinzeln von Infusionsbeutel anzugeben, das weitgehend ohne Bediener in Handschuheingriffen auskommt und eine Berührung der eigentlichen Infusionsbeutel möglichst komplett vermeidet.On the basis of this known prior art, the invention is based on the object of specifying an improved method for unpacking and separating infusion bags, which largely works without an operator in gloves and avoids touching the actual infusion bag as completely as possible.

Das erfindungsgemäße Verfahren ist durch die Merkmale des Hauptanspruchs 1 gegeben. Sinnvolle Weiterbildungen der Erfindung sind Gegenstand von sich an diesen Anspruch anschließenden weiteren Ansprüchen.The method according to the invention is given by the features of main claim 1. Useful further developments of the invention are the subject of further claims which follow this claim.

Bei dem erfindungsgemäßen Verfahren zum Entpacken und Vereinzeln von Infusionsbeuteln wird zunächst eine Umverpackung mittels einer Öffnungsvorrichtung maschinell geöffnet. In dieser Umverpackung sind die Infusionsbeutel gruppenweise an einer Haltevorrichtung befestigt. Nach dem Öffnen der Umverpackung werden die Infusionsbeutel mittels einer Separiervorrichtung von der Umverpackung separiert. Die einzelnen Infusionsbeutel bleiben während dieses Schrittes an der Halteeinrichtung befestigt. Mittels einer Positioniervorrichtung wird nun jede Halteeinrichtung mit den daran befestigten Infusionsbeuteln in einer Transportvorrichtung positioniert, so dass die Infusionsbeutel einer weiterverarbeitenden Vorrichtung zugeführt werden können.In the method according to the invention for unpacking and separating infusion bags, an outer packaging is first opened automatically by means of an opening device. In this outer packaging, the infusion bags are attached in groups to a holding device. After opening the outer packaging, the infusion bags are separated from the outer packaging by means of a separation device. The individual infusion bags remain attached to the holding device during this step. By means of a positioning device, each holding device with the infusion bags attached is now positioned in a transport device so that the infusion bags can be fed to a device for further processing.

In der Umverpackung kann in einer ersten Ausführungsform lediglich eine Gruppe von Infusionsbeuteln vorhanden sein. Dies kann insbesondere bei Umverpackungen in Form von Beuteln, beispielsweise in Form von Schlauch- oder Siegelbeuteln, der Fall sein. Alternativ dazu können in einer zweiten Ausführungsform mehrere Gruppen von Infusionsbeuteln in einer Umverpackung vorhanden sein, wobei jede Gruppe an einer eigenen Halteeinrichtung befestigt ist. Dies kann insbesondere bei solchen Umverpackungen der Fall sein, die über ein wannenartiges Behältnis für die Infusionsbeutel verfügen. Abhängig von der Tiefe des wannenartigen Behältnisses können die einzelnen Halteeinrichtungen mit den Infusionsbeuteln fächerartig in dem wannenartigen Behältnis liegen oder nebeneinander in dem wannenartigen Behältnis eingehängt vorliegen.In a first embodiment, only one group of infusion bags can be present in the outer packaging. This can be the case in particular with outer packaging in the form of bags, for example in the form of tubular or sealed bags. Alternatively, in a second embodiment, several groups of infusion bags can be present in an outer packaging, each group being fastened to its own holding device. This can be the case in particular with such outer packaging that has a tub-like container for the infusion bag. Depending on the depth of the tub-like container, the individual holding devices with the infusion bags can lie fan-like in the tub-like container or they can be suspended next to one another in the tub-like container.

Bei der Verwendung eines wannenartigen Behältnisses als Umverpackung kann dieses wannenartige Behältnis vorzugsweise mit einer aufgesiegelten Deckelfolie verschlossen sein. Durch die Öffnungsvorrichtung kann in diesem Fall die Deckelfolie entfernt werden. Dies kann vorzugsweise durch ein Abziehen der Deckelfolie erfolgen. Grundsätzlich wäre es auch möglich, eine Öffnung in die Deckelfolie zu schneiden, um die Umverpackung zu öffnen.When a tub-like container is used as the outer packaging, this tub-like container can preferably be closed with a sealed-on cover film. In this case, the cover film can be removed through the opening device. This can preferably be done by peeling off the cover film. In principle, it would also be possible to cut an opening in the cover film in order to open the outer packaging.

Bei der Verwendung einer Umverpackung in Form eines Beutels kann das Öffnen des Beutels in einer besonders einfachen Art und Weise durch das Aufschneiden des Beutels erfolgen. Der Beutel kann dazu lediglich mit einem Schlitz versehen werden. Es wäre auch möglich, einen Teil des Beutels durch einen Schnitt abzutrennen, um die Umverpackung zu öffnen.When using outer packaging in the form of a bag, the bag can be opened in a particularly simple manner by cutting open the bag. The bag can only be provided with a slit for this purpose. It would also be possible to cut off part of the bag in order to open the outer packaging.

Die geöffnete Umverpackung kann anschließend von der Separiervorrichtung angekippt werden. Dadurch können die Infusionsbeutel mit der Halteeinrichtung aus der geöffneten Umverpackung herausrutschen. Ein solches Herausrutschen der Infusionsbeutel ist sowohl bei einem Beutel als Umverpackung als auch bei einem flachen wannenartigen Behältnis als Umverpackung möglich.The opened outer packaging can then be tilted by the separating device. This allows the infusion bags with the holding device to slip out of the opened outer packaging. Such a slipping out of the infusion bag is possible both with a bag as outer packaging and with a flat tub-like container as outer packaging.

Sofern die Halteeinrichtungen dagegen in dem wannenartigen Behältnis eingehängt vorliegen, können diese mitsamt den Infusionsbeuteln von der Separiervorrichtung gegriffen und entnommen werden.If, on the other hand, the holding devices are suspended in the tub-like container, they can be gripped and removed from the separating device together with the infusion bags.

Grundsätzlich ist es möglich, die Infusionsbeutel gruppenweise einer weiterverarbeitenden Vorrichtung zuzuführen. In diesem Fall müsste lediglich die Halteeinrichtung ausgerichtet und in einer definierten Lage an eine Transportvorrichtung übergeben werden. Dieser Verfahrensschritt kann von der Positioniervorrichtung übernommen werden. Die Infusionsbeutel können anschließend gruppenweise beispielsweise mit der gewünschten Flüssigkeit befüllt werden.In principle, it is possible to feed the infusion bags in groups to a device for further processing. In this case, only the holding device would have to be aligned and transferred to a transport device in a defined position. This process step can be taken over by the positioning device. The infusion bags can then be filled in groups, for example with the desired liquid.

In einer bevorzugten Ausführungsform können die Infusionsbeutel vor der Übergabe an die weiterverarbeitende Vorrichtung von der Halteeinrichtung getrennt werden. Die Infusionsbeutel können somit einzeln weiterverarbeitet werden. Dies hat den Vorteil, dass die Bauweise der weiterverarbeitenden Vorrichtung in der Regel unverändert bestehen bleiben kann, da die weiterverarbeitende Vorrichtung bislang ebenfalls die bereits vereinzelten und ausgerichteten Infusionsbeutel zugeführt bekam. Die Trennung der Infusionsbeutel von der Halteeinrichtung kann dabei insbesondere von der Positioniervorrichtung oder von der Transportvorrichtung durchgeführt werden. Vorzugsweise können die Infusionsbeutel während des Trennens von der Halteeinrichtung unmittelbar vereinzelt werden, so dass kein separater Vereinzelungs-Vorgang mehr erforderlich ist. Die Infusionsbeutel können nach dem Trennen oder auch unmittelbar während des Trennvorgangs von der Halteeinrichtung direkt ausgerichtet werden, so dass eine definierte Übergabe an eine weiterverarbeitende Vorrichtung möglich ist. Dadurch kann ein separater Verfahrensschritt für die Ausrichtung der Infusionsbeutel gespart werden.In a preferred embodiment, the infusion bags can be separated from the holding device before they are transferred to the further processing device. The infusion bags can thus be further processed individually. This has the advantage that the construction of the further processing device can generally remain unchanged, since the further processing device has so far also received the already separated and aligned infusion bags. The separation of the infusion bag from the holding device can in particular from the positioning device or from the Transport device are carried out. The infusion bags can preferably be separated immediately during separation from the holding device, so that a separate separation process is no longer necessary. The infusion bags can be aligned directly by the holding device after the separation or also immediately during the separation process, so that a defined transfer to a further processing device is possible. This saves a separate method step for aligning the infusion bags.

Weitere Vorteile und Merkmale der Erfindung sind en in den Ansprüchen ferner angegebenen Merkmalen sowie den nachstehenden Ausführungsbeispielen zu entnehmen.Further advantages and features of the invention can be found in the features further specified in the claims and in the exemplary embodiments below.

WEGE ZUM AUSFÜHREN DER ERFINDUNGWAYS OF CARRYING OUT THE INVENTION

In den Fig. 1 bis 6 ist eine erste Variante des erfindungsgemäßen Verfahrens schrittweise dargestellt. Mehrere Infusionsbeutel 10 sind an einer Halteeinrichtung 12 befestigt. Im vorliegenden Fall ist die Halteeinrichtung 12 mit den sterilisierten Infusionsbeutel 10 in einem Schlauchbeutel 20 als Umverpackung verpackt. Statt des Schlauchbeutels 20 könnte beispielsweise auch ein Siegelbeutel oder ein anderer Beutel als Umverpackung verwendet werden. Die Umverpackung 20 wird zunächst an der Außenseite desinfiziert und anschließend in einen Reinraum eingebracht, in dem die weiteren Verfahrensschritte mittels entsprechender Vorrichtungen durchgeführt werden.In the Figs. 1 to 6 a first variant of the method according to the invention is shown step by step. Several infusion bags 10 are attached to a holding device 12. In the present case, the holding device 12 with the sterilized infusion bag 10 is packed in a tubular bag 20 as an outer packaging. Instead of the tubular bag 20, for example, a sealed bag or another bag could also be used as the outer packaging. The outer packaging 20 is first disinfected on the outside and then introduced into a clean room, in which the further process steps are carried out using appropriate devices.

Gemäß Fig. 2 wird der Schlauchbeutel 20 zunächst durch eine hier nur schematisch dargestellte Öffnungsvorrichtung 50 aufgeschnitten. Der Schnitt 22 erfolgt dabei in der Nähe der Halteeinrichtung 12, um die Infusionsbeutel 10 beim Schneidvorgang nicht versehentlich zu beschädigen. Anschließend wird der abgetrennte Teil 24 der Umverpackung 20' entfernt (Fig. 3).According to Fig. 2 the tubular bag 20 is first cut open by an opening device 50, which is only shown schematically here. The cut 22 is made in the vicinity of the holding device 12 in order not to accidentally damage the infusion bag 10 during the cutting process. The separated part 24 of the outer packaging 20 'is then removed ( Fig. 3 ).

Die geöffnete Umverpackung 20' wird nunmehr durch eine ebenfalls lediglich schematisch dargestellte Separiervorrichtung 52 angekippt, so dass die offene Seite 26 der Umverpackung 20' nach unten weist. Dadurch rutschen die Infusionsbeutel 10 mit der Halteeinrichtung 12 aus der geöffneten Umverpackung 20' heraus (siehe Fig. 5). Die leere Umverpackung 20' kann anschließend entsorgt werden, während die Halteeinrichtung 12 mit den Infusionsbeuteln 10 weiter verarbeitet werden kann. In der Regel wird die Halteeinrichtung 12 mit den daran befestigten Infusionsbeuteln 10 von einer Positioniervorrichtung 54 an eine Transportvorrichtung 56 übergeben.The opened outer packaging 20 'is now tilted by a separating device 52, likewise shown only 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 slide out of the opened outer packaging 20 '(see FIG Fig. 5 ). The empty outer packaging 20 ′ can then be disposed of, while 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 attached to it is transferred from a positioning device 54 to a transport device 56.

Anstelle des Schlauchbeutels 20 kann auch ein flaches wannenartiges Behältnis 30 zur Lagerung der an der Halteeinrichtung 12 befestigten Infusionsbeutel 10 verwendet werden (siehe Fig. 7 bis 9). Das wannenartige Behältnis 30 ist mit einer aufgesiegelten Deckelfolie 32 verschlossen. Nach der Dekontamination der Außenseiten des verschlossenen wannenartigen Behältnisses 30 kann die Deckelfolie 32 in einem Reinraum von einer hier nur schematisch dargestellten Öffnungsvorrichtung 50.2 entfernt werden (siehe Fig. 8 und 9). Im vorliegenden Beispielsfall wird die Deckelfolie 32 dabei vollständig von dem wannenartigen Behältnis 30 abgezogen. Alternativ dazu könnte auch eine flächige Öffnung in die Deckelfolie 32 eingeschnitten werden, durch die die einzelnen Halteeinrichtungen 12 mit Infusionsbeuteln 10 entnommen werden könnten.Instead of the tubular bag 20, a flat tub-like container 30 can also be used for storing the infusion bags 10 attached to the holding device 12 (see FIG Figures 7 to 9 ). The tub-like container 30 is closed with a sealed-on cover film 32. After the outside of the closed tub-like container 30 has been decontaminated, the cover film 32 can be removed in a clean room from an opening device 50.2, which is only shown schematically here (see FIG Figures 8 and 9 ). In the present example, the cover film 32 is completely pulled off the tub-like container 30. As an alternative to this, a flat opening could also be cut into the cover film 32, through which the individual holding devices 12 with infusion bags 10 could be removed.

Wie Fig. 10 zu entnehmen ist, können in einem wannenartigen Behältnis 30 mehrere Halteeinrichtungen 12 mit daran befestigten Infusionsbeuteln 10 gelagert und transportiert werden. Die einzelnen Halteeinrichtungen 12 (siehe auch Fig. 11) sind dabei jeweils mit mehreren Infusionsbeuteln 10 bestückt, wobei die Infusionsbeutel 10 fächerartig überlappend angeordnet sind. Die Infusionsbeutel 10 sind im vorliegenden Beispielsfall über einen Schlauchansatz 14 an der Halteeinrichtung 12 befestigt. Der Schlauchansatz 14 jedes Infusionsbeutels 10 ist dabei in der Halteeinrichtung 12 festgeklemmt. Die Abstände zweier benachbarter Schlauchansätze 14 sind dabei jeweils identisch, so dass eine exakte Ausrichtung der Infusionsbeutel 10 an der Halteeinrichtung 12 gegeben ist. Diese exakte Ausrichtung der Infusionsbeutel 10 ermöglicht die definierte Weiterverarbeitung und Übergabe der vereinzelten Infusionsbeutel 10 an eine beliebige weiterverarbeitende Vorrichtung, ohne dass eine manuelle Ausrichtung durch Bediener erforderlich wäre.As Fig. 10 As can be seen, several holding devices 12 with infusion bags 10 attached can be stored and transported in a tub-like container 30. The individual holding devices 12 (see also Fig. 11 ) are each equipped with several infusion bags 10, the infusion bags 10 being arranged in a fan-like overlapping manner. In the present example, the infusion bags 10 are fastened to the holding device 12 via a hose attachment 14. The tube attachment 14 of each infusion bag 10 is clamped in the holding device 12. The distances between two adjacent tube attachments 14 are identical in each case, so that the infusion bag 10 is precisely aligned on the holding device 12. This exact alignment of the infusion bags 10 enables the defined further processing and transfer of the separated infusion bags 10 to any further processing device without the need for manual alignment by the operator.

Innerhalb des wannenartigen Behältnisses 30 liegen mehrere Halteeinrichtungen 12 leicht versetzt übereinander. Sofern die Seitenwände 34 des wannenartigen Behältnisses 30 ausreichend flach verlaufen, könnte die Entnahme der einzelnen Halteeinrichtungen 12 durch ein Kippen des geöffneten wannenartigen Behältnisses 30' erfolgen. Alternativ dazu könnten die einzelnen Halteeinrichtungen 12 auch mittels einer Greifvorrichtung als Separiervorrichtung 52.2 aus dem geöffneten wannenartigen Behältnis 30 entnommen werden. Die einzelnen Halteeinrichtungen 12 mit den Infusionsbeuteln 10 können anschließend weiter bearbeitet werden.Within the tub-like container 30, several holding devices 12 are slightly offset one above the other. If the side walls 34 of the tub-like container 30 run sufficiently flat, the individual holding devices 12 could be removed by tilting the opened tub-like container 30 '. As an alternative to this, the individual holding devices 12 could also be removed from the opened tub-like container 30 by means of a gripping device as a separating device 52.2. The individual holding devices 12 with the infusion bags 10 can then be processed further.

Anstelle des flachen wannenartigen Behältnisses 30 zur Lagerung der Halteeinrichtung 12 mit Infusionsbeuteln 10 könnte auch ein vergleichsweise tiefes wannenartiges Behältnis 40 verwendet werden (siehe Fig. 12 bis 14). In diesem wannenartigen Behältnis 40 könnten die einzelnen Halteeinrichtungen 12 so eingehängt vorhanden sein, dass die Infusionsbeutel 10 jeweils nach unten hängen (siehe Fig. 14). Das wannenartige Behältnis 40 ist mit einer aufgesiegelten Deckelfolie 42 verschlossen. Nach der Dekontamination der Außenseiten des verschlossenen wannenartigen Behältnisses 40 kann die Deckelfolie 42 in einem Reinraum von einer hier nicht dargestellten Öffnungsvorrichtung entfernt werden (siehe Fig. 13 und 14). Im vorliegenden Beispielsfall wird die Deckelfolie 42 dabei vollständig von dem wannenartigen Behältnis 40 abgezogen. Alternativ dazu könnte auch eine flächige Öffnung in die Deckelfolie 42 eingeschnitten werden, durch die die einzelnen Halteeinrichtungen 12 mit Infusionsbeuteln 10 entnommen werden könnten. Nach dem Entfernen der Deckelfolie 42 können die einzelnen Halteeinrichtungen 12 mit den Infusionsbeuteln 10 mittels einer hier nicht dargestellten Greifvorrichtung aus dem geöffneten wannenartigen Behältnis 40' entnommen werden. Die einzelnen Halteeinrichtungen 12 mit den Infusionsbeuteln 10 können anschließend weiter bearbeitet werden.Instead of the flat tub-like container 30 for storing the holding device 12 with infusion bags 10, a comparatively deep tub-like container 40 could also be used (see FIG Figures 12-14 ). The individual holding devices 12 could be suspended in this tub-like container 40 in such a way that the infusion bags 10 each hang down (see FIG Fig. 14 ). The tub-like container 40 is closed with a sealed-on cover film 42. After the outside of the closed tub-like container 40 has been decontaminated, the cover film 42 can be removed from an opening device (not shown here) in a clean room (see FIG Figures 13 and 14 ). In the present example, the cover film 42 is completely peeled off from the tub-like container 40. As an alternative to this, a flat opening could also be cut into the cover film 42, through which the individual holding devices 12 with infusion bags 10 could be removed. After removing the cover film 42, the individual holding devices 12 with the infusion bags 10 can be removed from the opened tub-like container 40 'by means of a gripping device (not shown here). The individual holding devices 12 with the infusion bags 10 can then be processed further.
