Furthermore a container, in particular a bag, with such a withdrawal and injection system is described.

Description

Entnahme- und Zuspritzsystem für medizinische Lösungen und Behälter mit einem derartigen Entnahme- und Zuspritzsystem Withdrawal and injection system for medical solutions and containers with such a withdrawal and injection system
Die Erfindung betrifft ein Entnahme- und Zuspritzsystem für medizinische Lösungen, insbesondere für Infusionslösungsbeutel, das ein in den Beutel einschweißbares Basisteil mit einem Entnahme- und Zuspritzteil aufweist. Darüber hinaus bezieht sich die Erfindung auf einen Behälter, insbesondere einen Infusionslösungsbeutel mit einem derartigen Entnahme- und Zuspritzsystem.The invention relates to a removal and injection system for medical solutions, in particular for infusion solution bags, which has a base part which can be welded into the bag and has a removal and injection part. Furthermore, the invention relates to a container, in particular an infusion solution bag with such a removal and injection system.
Medizinische Lösungen, insbesondere Infusionslösungen werden im allgemeinen in Folienbeuteln bereitgestellt. In die Beutelfolie sind Trägersysteme, beispielsweise Spritzgußteile, Schläuche oder dgl. eingesiegelt, die wiederum die eigentlichen Verbindungssysteme, z. B. Konnektoren, Septen oder dgl., aufnehmen.Medical solutions, in particular infusion solutions, are generally provided in plastic bags. Carrier systems, for example injection molded parts, hoses or the like, are sealed into the bag film and in turn the actual connection systems, e.g. B. connectors, septa or the like, record.
Es sind Entnahme- und Zuspritzsysteme bekannt, die über einen mit einer Membran verschlossenen Entnahmeteil und einen Zuspritzteil verfugen. Zur Entnahme der Lösung wird der Entnahmeteil von einem Spike durchstochen, an den eine Schlauchleitung angeschlossen ist. Der Zuspritzteil erlaubt das Zuspritzen einer weiteren Lösung mit einer Injektionsspritze.Extraction and injection systems are known which have an extraction part closed with a membrane and an injection part. To remove the solution, the removal part is pierced by a spike to which a hose line is connected. The injection part allows another solution to be injected with an injection syringe.
Die EP 0 732 114 A 1 und die DE 24 58 220 A 1 beschreiben Entnahme- und Zuspritzsysteme für enterale Nährlösungen enthaltende Beutel, bei denen es sich um relativ aufwendige Schraubverschlüsse handelt.EP 0 732 114 A 1 and DE 24 58 220 A 1 describe removal and injection systems for bags containing enteral nutrient solutions, which are relatively complex screw closures.
Die DE 33 05 365 C2 beschreibt ein Entnahme- und Zuspritzsystem für einen Folienbeutel, das aus einem Basisteil sowie einem Entnahme- und Zuspritzteil besteht. Der Basisteil ist in der Art eines Schiffchens ausgebildet und nimmt als Entnahme- und Zuspritzteil zwei kurze Schlauchstücke auf, die über das Basisteil außen vorstehen oder mit diesem bündig abschließen können. Die in der Art eines Schiffchens ausgebildeten Entnahme- und Zuspritzsysteme haben sich in der Praxis bewährt. Nachteilig ist jedoch deren relativ aufwendige Herstellung.DE 33 05 365 C2 describes a removal and injection system for a film bag, which consists of a base part and a removal and injection part. The base part is designed in the manner of a boat and, as a removal and injection part, takes up two short pieces of hose which protrude beyond the base part or can be flush with it. The extraction and injection systems, which are designed like a boat, have proven themselves in practice. However, their relatively complex manufacture is disadvantageous.
Der Erfindung liegt die Aufgabe zugrunde, ein Entnahme- und Zuspritzsystem für medizinische Lösungen zu schaffen, das sich einerseits in großen Stückzahlen aus möglichst wenigen Teilen kostengünstig herstellen, einfach in die Behälter einsetzen und andererseits leicht handhaben läßt. Eine weitere Aufgabe der Erfindung liegt darin, einen Behälter für medizinische Lösungen mit einem derartigen Entnahme- und Zuspritzsystem bereitzustellen.The invention has for its object to provide a removal and injection system for medical solutions that can be produced inexpensively in large quantities from as few parts as possible, simply inserted into the container and on the other hand easy to handle. Another object of the invention is to provide a container for medical solutions with such a removal and injection system.
Die Lösung dieser Aufgabe erfolgt erfindungsgemäß mit den Merkmalen des Patentanspruchs 1 bzw. 12.This object is achieved according to the invention with the features of patent claims 1 and 12.
Bei dem erfindungsgemäßen Entnahme- und Zuspritzsystem sind Entnahme- und Zuspritzteil mit einem flachen Steg miteinander verbunden. Die flache Bauweise des Basisteils mit der integrierten Entnahme- und Zuspritzstelle führt nicht nur zu einer Materialersparnis, sondern auch zu einer vereinfachten Herstellung. Das Entnahme- und Zuspritzsystem ist insbesondere zum Einbau in einen Folienbeutel bestimmt.In the removal and injection system according to the invention, the removal and injection part are connected to one another with a flat web. The flat design of the base part with the integrated removal and injection point not only saves material, but also simplifies production. The removal and injection system is particularly intended for installation in a foil bag.
Zwischen Entnahme- und Zuspritzteil ist der flache Steg unter Bildung einer verschließbaren Öffnung wulstartig erweitert. Die Öffnung in dem Steg dient sowohl zum Befüllen des Behälters als auch zur Vereinfachung dessen Handhabung während des Herstellungsvorgangs.Between the removal and injection part, the flat web is bulged to form a closable opening. The opening in the web serves both to fill the container and to simplify its handling during the manufacturing process.
Zum Transport oder zur lagerichtigen und verdrehsicheren Positionierung kann ein Fixiemngsdom in die Öffnung eingesetzt werden. Mittels eines Fülldoms kann der Behälter durch die Öffnung befüllt werden. Die Fixierung und Befüllung können aber auch mittels eines gemeinsamen Doms folgen, der in die Öffnung eingesetzt wird, wodurch sich die Handhabung noch weiter vereinfachen läßt. Nach dem Befüllen des Behälters wird die Öffnung einfach dadurch verschlossen, daß der Steg zusammengedrückt und verschweißt wird.A fixing dome can be inserted into the opening for transport or for correct positioning and rotation. The container can be filled through the opening by means of a filling dome. The fixation and filling can also follow by means of a common dome, which is inserted into the opening, which makes handling even easier. After filling the container, the opening is simply closed by compressing and welding the web.
Das System verfügt sowohl über einen Entnahme- als auch einen Zuspritzteil. Mehrere Entnahme- und/oder Zuspritzteile sind aber ebenfalls möglich.The system has both an extraction and an injection part. Several removal and / or injection parts are also possible.
Der Basisteil stellt einen Konnektorteil dar, der es erlaubt, Konnektionssysteme unterschiedlicher Ausbildung auf- oder einzubauen. Da alle Konnektionssysteme auf dem gleichen Basisteil aufbauen, können die maschinenseitigen Teile zum Transport und Fixieren unverändert bleiben, so daß ein einfacher und rascher Wechsel möglich ist. Auch der Füll- und Verschließprozeß ist unabhängig von der Art des Entnahme- und Zuspritzsystems immer der gleiche.The base part represents a connector part, which allows connection systems of different training to be built or installed. Since all connection systems are based on the same base part, the machine-side parts for transport and fixing can remain unchanged, so that a simple and quick change is possible. The filling and closing process is always the same regardless of the type of dispensing and injection system.
Zur Verbesserung der Fixierung und zur Vereinfachung des Verschweißens weist die Öffnung in dem Steg vorzugsweise einen in Richtung des Entnahme- und Zuspritzteils spitz auslaufenden Querschnitt auf. Da die Öffnung nicht kreisrund ist, kann der Dom in der Öffnung klemmend gehalten werden. Darüber hinaus läßt sich der Steg im Bereich der wulstartigen Erweiterung aufgrund dieser Formgebung besonders leicht zusammendrücken und zu einem flachen Verbindungsstück verschweißen.In order to improve the fixation and to simplify the welding, the opening in the web preferably has a cross section which tapers in the direction of the removal and injection part. Since the opening is not circular, the dome can be held clamped in the opening. In addition, the web in the area of the bulge-like expansion can be pressed together particularly easily due to this shape and welded to form a flat connecting piece.
Entnahme-, Zuspritzteil und Steg sind vorzugsweise einstückiger Bestandteil des Basisteils. Vorzugsweise ist der Basisteil ein Spritzgießteil aus Polyolefin oder thermoplastischem Elastomer (TPE).The removal, injection part and web are preferably an integral part of the base part. The base part is preferably an injection molded part made of polyolefin or thermoplastic elastomer (TPE).
Für den Fall, daß das Basisteil aus einem Material bestehen sollte, das nicht mit der Beutelfolie versiegelt werden kann, ist das Basisteil zumindest teilweise mit einer siegelfähigen Schicht überzogen, insbesondere einer mit dem bekannten Polyolefinfolien der Beutel verschweißbaren Kunststoffschicht, die auf PP oder PE basiert. Zur Verhinderung einer Luftblasenbildung beim Verschweißen von Basisteil und Beutelfolie ist der Basisteil an den Außenseiten vorzugsweise mit Rippen versehen, mit denen die Folie versiegelt wird.In the event that the base part should consist of a material that cannot be sealed with the bag film, the base part is at least partially covered with a sealable layer, in particular a plastic layer that can be welded to the known polyolefin films of the bag, which is based on PP or PE , To prevent air bubbles from forming when the base part and bag film are welded together, the base part is preferably provided on the outside with ribs with which the film is sealed.
Die den Entnahme- und/oder Zuspritzteil verschließende Membran ist vorzugsweise in dem Basisteil angeordnet. Sie kann beispielsweise aus einer Kunststoffplatte bestehen, die ebenfalls mit dem Basisteil einstückig ist.The membrane closing the removal and / or injection part is preferably arranged in the base part. For example, it can consist of a plastic plate, which is also in one piece with the base part.
Bei dem Zuspritzteil ist vorzugsweise oberhalb der Membran ein durchstechbares Septum angeordnet, das einen dauerhaften Verschluß auch nach dem Durchstechen der Membran mit einer Injektionskanüle erlaubt. Die das Septum abdeckende Membran kann auch entfallen, ebenso kann die Membran selbst auch das Septum darstellen.In the injection part, a pierceable septum is preferably arranged above the membrane, which permits permanent closure even after the membrane has been pierced with an injection cannula. The membrane covering the septum can also be omitted, and the membrane itself can also represent the septum.
Der Entnahme- und/oder Zuspritzteil schließen mit der Außenseite des Basisteils im wesentlichen bündig ab. Damit sind nach außen vorstehende Anschlußteile mit Ausnahme von Anstichstellen Abdeckungen oder dgl. nicht vorhanden. Daraus ergibt sich eine kurze Baulänge, wodurch auch die Abmessung und die für die Herstellung erforderliche Materialmenge weiter verringert wird.The removal and / or injection part are essentially flush with the outside of the base part. This means that there are no protruding connecting parts with the exception of tapping points, covers or the like. This results in a short overall length, which also further reduces the dimensions and the amount of material required for production.
Im Bereich der Entnahme- und/oder Zuspritzstelle kann das Basisteil unterschiedlich ausgebildet sein, so daß eine Optimierung der Geometrie auf die jeweilige Anwendung möglich ist. Bei einer Ausführungsform weisen der Entnahme- und/oder Zuspritzteil einen im wesentlichen hohlzylindrischen Abschnitt auf, der mit dem Basisteil einstückig ist.In the area of the removal and / or injection point, the base part can be designed differently, so that the geometry can be optimized for the respective application. In one embodiment, the removal and / or injection part have an essentially hollow cylindrical section which is integral with the base part.
Um eine Verletzung der Beutelfolie mit dem Spike des Überleitungssystems bzw. der Kanüle der Injektionsspritze zum Entnehmen bzw. Zuspritzen von Flüssigkeit auf jeden Fall zu verhindern, schließt sich bei einer bevorzugten Ausfuhmngsform an dem Basisteil im Bereich des Entnahme- und/oder Zuspritzteils eine rohrformige Abdeckung an, die sich nach innen erstreckt. Die sich in das Beutelinnere erstreckende Abdeckung hat nicht nur eine Schutzfunktion, sondern kann auch der Führung des Spike bzw. der Kanüle dienen. Die Abdeckung braucht den Entnahme- und/oder Zuspritzkanal nicht allseitig zu umschließen. Es genügt den Kanal nur an den Seiten abzudecken, an der die Gefahr des Durchstechens der Beutelfolie besteht.In order to prevent injury to the pouch film with the spike of the transfer system or the cannula of the injection syringe for withdrawing or injecting liquid, in a preferred embodiment, a tubular cover closes on the base part in the region of the removal and / or injection part that extends inwards. The cover extending into the inside of the bag not only has a protective function, but also can also be used to guide the spike or cannula. The cover does not have to enclose the extraction and / or injection channel on all sides. It is sufficient to cover the channel only on the sides where there is a risk of puncturing the bag film.
In einer weiteren bevorzugten Ausführungsform ist die Abdeckung des Entnahmeteils ein in Längsrichtung geschlitztes Rohrstück. Der bzw. die Schlitze in Längsrichtung ermöglichen, daß der Beutel vollständig entleert wird. Anstelle von Längsschlitzen können aber auch Bohrungen oder die dgl. in der Abdeckung vorgesehen sein.In a further preferred embodiment, the cover of the removal part is a piece of pipe slotted in the longitudinal direction. The slot or slots in the longitudinal direction allow the bag to be completely emptied. Instead of longitudinal slots, bores or the like can also be provided in the cover.
Zur sterilen Abdeckung der Membran und als Originalitätssicherung sind das Entnahme- und/oder Zuspritzteil in einer weiteren bevorzugten Ausgestaltung mit einer Abreißfolie verschlossen. Da Entnahme- und/oder Zuspritzteil vorzugsweise mit dem Basisteil im wesentlichen bündig abschließen, kann die Abreißfolie Bestandteil der Beutelfolie sein. Es können aber auch zusätzliche Abreißfolien oder Twist-off Abdeckungen vorgesehen sein.In a further preferred embodiment, the removal and / or injection part are closed with a tear-off film for sterile covering of the membrane and as tamper-evident device. Since the removal and / or injection part is preferably essentially flush with the base part, the tear-off film can be part of the bag film. However, additional tear-off films or twist-off covers can also be provided.

Figur 1 zeigt einen Längsschnitt durch das Entnahme- und Zuspritzsystem, während in Figur 2 das Entnahme- und Zuspritzsystem in der Draufsicht dargestellt ist.Figure 1 shows a longitudinal section through the removal and injection system, while in Figure 2, the removal and injection system is shown in plan view.
Das Entnahme- und Zuspritzsystem 1 ist ein einstückiges Spritzgußteil, insbesondere aus einem thermoplastischen Elastomer (TPE). Es weist einen nach Art eines Schiffchens ausgebildeten Basisteil 2 auf, der mit der Folie eines Folienbeutels versiegelt wird. Der Basisteil 2 umfaßt ein Entnahmeteil 3 und ein Zuspritzteil 4, die mit einem flachen Steg 35 miteinander verbunden sind.The removal and injection system 1 is a one-piece injection molded part, in particular made of a thermoplastic elastomer (TPE). It has a base part 2 designed in the manner of a boat, which is sealed with the film of a film bag. The base part 2 comprises a removal part 3 and an injection part 4, which are connected to one another by a flat web 35.
Der in den Beutel eingeschweißte Basisteil 2 weist eine nach außen weisende Außenseite 5 und eine nach innen weisende Innenseite 6 sowie zwei mit der Beutelfolie versiegelte Längsseiten 7,8 auf. An seinen Enden läuft der Basisteil 1 spitz zu, wobei im Bereich des Entnahmeteils 3 und des Zuspritzteils 4 der Basisteil 2 eine Breite hat, die dem Durchmesser des Entnahme- und Zuspritzteils entspricht (Fig. 2).The base part 2 welded into the bag has an outside 5 and an inside 6 and two longitudinal sides 7, 8 sealed with the bag film. The base part 1 tapers at its ends, the base part 2 having a width in the region of the removal part 3 and the injection part 4 which corresponds to the diameter of the removal and injection part (FIG. 2).
Der Entnahme- und Zuspritzteil schließen mit der Außenseite 5 des Basisteils im wesentlichen bündig ab. Sie werden jeweils durch einen Kanal 9,10 in dem Basisteil 2 gebildet. Der Kanal 9 des Entnahmeteils 3 hat einen Durchmesser, der dem des nicht dargestellten Spike des Überleitungsschlauchs zum Entnehmen der Flüssigkeit entspricht, während der Durchmesser des Kanals 10 des Zuspritzteils 4 kleiner ist. Die Kanäle 9,10 werden von einer durchstechbaren Kunststoffmembran 11,12 steril verschlossen, die mit dem Basisteil 2 einstückig ist. Zur dauerhaften Abdichtung des Zuspritzteils ist in den Kanal 10 oberhalb der Membran 12 noch ein durchstehbares Septum 13 eingesetzt. An seiner Außenseite 5 weist der Basisteil 2 einen ringförmigen Ansatz 14, der die Öffnung des Kanals 9 und einen ringförmigen Ansatz 15 auf, der die Öffnung des Kanals 10 umschließt. Die ringförmigen Ansätze 14,15 dienen der besseren Führung des Spike bzw. der Injektionskanüle.The removal and injection part are essentially flush with the outside 5 of the base part. They are each formed by a channel 9, 10 in the base part 2. The channel 9 of the removal part 3 has a diameter which corresponds to that of the spike of the transfer hose (not shown) for removing the liquid, while the diameter of the channel 10 of the injection part 4 is smaller. The channels 9, 10 are sterile closed by a pierceable plastic membrane 11, 12, which is integral with the base part 2. A permanent septum 13 is inserted in the channel 10 above the membrane 12 for permanent sealing of the injection part. On its outside 5, the base part 2 has an annular extension 14 which surrounds the opening of the channel 9 and an annular extension 15 which surrounds the opening of the channel 10. The annular projections 14, 15 serve to better guide the spike or the injection cannula.
An den Kanal 9 des Entnahmeteils 3 und den Kanal 10 des Zuspritzteils 4 schließen sich an der Innenseite 6 des Basisteils 2 jeweils ein Rohrstück 16,17 an. Zumindest das Rohrstück 16 des Entnahmeteils weist zwei Schlitze 18,19 auf, die in der Ebene des Basisteils 2 liegen (Figur 3). Wenn die Membran 11 des Entnahmeteils 3 von dem Spike durchstochen wird, dient das Rohrstück 16 zum einen als Führung für den Spike und zum anderen als Abdeckung, die ein Durchstechen des Folienbeutels verhindert. Über die seitlichen Schlitze 18,19 in dem Rohrstück 16 des Entnahmeteils kann der Beutel vollständig entleert werden. Auch das Rohrstück 17 des Zuspritzteils 4 dient vor allem dem Schutz der Beutelfolie.A pipe section 16, 17 adjoins the channel 9 of the removal part 3 and the channel 10 of the injection part 4 on the inside 6 of the base part 2. At least the pipe section 16 of the removal part has two slots 18, 19 which lie in the plane of the base part 2 (FIG. 3). If the membrane 11 of the removal part 3 is pierced by the spike, the tube piece 16 serves on the one hand as a guide for the spike and on the other hand as a cover, which prevents the foil bag from being pierced. The bag can be completely emptied via the lateral slots 18, 19 in the pipe section 16 of the removal part. The pipe section 17 of the injection part 4 also serves primarily to protect the bag film.
Zwischen Entnahme- und Zuspritzteil 3, 4 ist der flache Steg 35 unter Bildung einer Öffnung 34 wulstartig erweitert. Die Öffnung 34 hat einen Querschnitt, der in Richtung des Entnahme- und Zuspritzteils spitz ausläuft, so daß sich die beiden Seitenränder 36, 37 des Steges im Bereich der Öffnung leicht zusammendrücken lassen.Between the removal and injection part 3, 4, the flat web 35 is expanded like a bead, forming an opening 34. The opening 34 has a cross section which tapers towards the removal and injection part, so that the two side edges 36, 37 of the web can be compressed slightly in the region of the opening.
Die Öffnung 34 dient zum einen zum Befüllen und zum anderen zum Fixieren des Beutels. Zum Fixieren des Beutels wird in die nicht kreisrunde, sondern an den Enden spitz auslaufende Öffnung ein Fixiemngsdom eingeführt, der zwischen den Seitenrändern 36, 37 klemmend gehalten wird. Damit läßt sich der Beutel lagerichtig und verdrehsicher transportieren und positionieren.The opening 34 serves on the one hand for filling and on the other hand for fixing the bag. To fix the bag, a fixing dome is inserted into the opening, which does not have a circular shape but tapers at the ends, and is held clampingly between the side edges 36, 37. This allows the bag to be transported and positioned in the correct position and secure against rotation.
Die Befüllung des Beutels erfolgt über einen Fülldom, der ebenfalls in die Öffnung 35 eingeführt wird. Zum Verschließen der Öffnung werden die beiden Außenwände 36, 37, die eine hohe Flexibilität haben, fest zusammengepreßt und miteinander verschweißt. Die Fixierung des Basisteils kann mit dem gleichen Dom erfolgen, wie das Befüllen des Beutels.The bag is filled via a filling dome, which is also inserted into the opening 35. To close the opening, the two outer walls 36, 37, which have a high degree of flexibility, are pressed tightly together welded together. The base part can be fixed with the same dome as the filling of the bag.
Der Basisteil 2 weist an beiden Außenseiten mehrere querverlaufende Stege 38 auf, die mit der Beutelfolie versiegelt werden. Fig. 4 zeigt eine Seitenansicht des Basisteils mit den Stegen.The base part 2 has a plurality of transverse webs 38 on both outer sides, which are sealed with the bag film. Fig. 4 shows a side view of the base part with the webs.
Figur 5 zeigt einen Folienbeutel mit einem Entnahme- und Zuspritzsystem, das in einen Folienbeutel eingeschweißt ist. Der Basisteil 20 ist als flacher Steg ausgebildet, der an seinen Enden spitz zuläuft, während der Entnahmeteil 21 und der Zuspritzteil 22 jeweils einen hohlzylindrischen Abschnitt 23,24 unterschiedlichen Durchmessers aufweisen, der mit dem Basisteil einstückig ist. Die hohlzylindrischen Abschnitte 23,24 schließen mit der Außenseite 25 des Basisteils bündig ab. An der Innenseite 26 des Basisteils 20 gehen die hohlzylindrischen Abschnitte 23, 24 in rohrförmige Abdeckungen 27, 28 über, wobei zumindest die Abdeckung des Entnahmeteils in Längsrichtung seitlich geschlitzt ist. Diese sind in Figur 4 nur in gestrichelten Linien dargestellt.FIG. 5 shows a film bag with a removal and injection system which is welded into a film bag. The base part 20 is designed as a flat web which tapers at its ends, while the removal part 21 and the injection part 22 each have a hollow cylindrical section 23, 24 of different diameters, which is integral with the base part. The hollow cylindrical sections 23, 24 are flush with the outside 25 of the base part. On the inside 26 of the base part 20, the hollow cylindrical sections 23, 24 merge into tubular covers 27, 28, with at least the cover of the removal part being slit laterally in the longitudinal direction. These are only shown in broken lines in FIG. 4.
Die Füll- und Fixierungsöffhung 34 ist durch Zusammendrücken des Entnahme- und Zuspritzteils miteinander verbindenden Stegs im Bereich der wulstartigen Erweiterung und Verschweißen der beiden Außenwände verschlossen worden, so daß der Steg über seine gesamte Länge zwischen Entnahme- und Zuspritzteil flach ausgebildet ist.The filling and fixing opening 34 has been closed by compressing the web connecting the removal and injection part in the region of the bulge-like expansion and welding of the two outer walls, so that the web is flat over its entire length between the removal and injection part.
Der Folienbeutel 29, der mit einer Infusionslösung gefüllt sein kann, besteht aus zwei übereinanderliegenden, an ihren Rändern miteinander verschweißten Kunststofffolien 30,31, die mit den Längsseiten des Basisteils 20 versiegelt sind. Die untere Beutelfolie 31 weist an ihrem oberen Rand vorstehende Laschen 32, 33 auf, die sich über die Öffnungen des Entnahme- und Zuspritzteils 21, 22 erstrecken und mit der Außenseite 25 des Basisteils versiegelt sind. Zum Entnehmen bzw. Zuspritzen von Flüssigkeiten werden die Laschen 32, 33 abgerissen, so daß die Füll- bzw. Entnahmeöffhung frei liegt. Für den Fall, daß das Entnahme- und Zuspritzsystem aus einem nicht mit der Beutelfolie versiegelbaren Material besteht, ist zumindest das Basisteil an seinen Längsseiten mit einer Schicht, insbesondere einer auf PP basierenden Kunststoffschicht überzogen, mit der sich die Beutelfolie, z.B. eine Polyolefinfolie versiegeln läßt.The film bag 29, which can be filled with an infusion solution, consists of two superposed plastic films 30, 31 welded together at their edges, which are sealed to the long sides of the base part 20. The lower pouch film 31 has on its upper edge protruding tabs 32, 33 which extend over the openings of the removal and injection part 21, 22 and are sealed to the outside 25 of the base part. To remove or inject liquids, the tabs 32, 33 are torn off, so that the filling or removal opening is exposed. In the event that the removal and injection system consists of a material that cannot be sealed with the bag film, at least the base part is coated on its long sides with a layer, in particular a PP-based plastic layer, with which the bag film, for example a polyolefin film, can be sealed ,
Die Figuren 7 und 8 zeigen zwei weitere Ausführungsbeispiele des Entnahme- und Zuspritzsystems in der Seitenansicht, die auf dem Basisteil von den Figuren 6a und 6b aufbauen. Der Basisteil unterscheidet sich von dem Basisteil des unter Bezugnahme auf die Figuren 1 bis 4 beschriebenen Ausführungsbeispiels des Entnahme- und Zuspritzsystems im wesentlichen durch die Dimensionierung der Entnahme- und Zuspritzöffnung 9, 10, die den gleichen Durchmesser haben. Die einander entsprechenden Teile sind mit den gleichen Bezugszeichen versehen.FIGS. 7 and 8 show a side view of two further exemplary embodiments of the removal and injection system, which are based on the base part from FIGS. 6a and 6b.
