Abstract

The closure consists of a hollow cone (1), consisting of a cone neck (2) and cone head (3), a membrane (4) situated in the cone head, a disc (5) situated over the membrane and made of an elastic material, if appropriate with a recess (6) serving as a puncture marking, and a cover (7) which tightly seals the disc (5) and has a tear-open arrangement (8). The closure is used for the accurately leakproof sealing of a transparent plastic bag containing an infusion solution. It can be sterilised and thus guarantees the sterility of the puncture surface for infusion devices, can be resealed after removal of the infusion device, can be opened quickly and without difficulty, and is designed in such a way that only inert materials come into contact with the infusion solution.

Description

Die Erfindung betrifft einen Verschluß für Plastikinfusionslösungsbeutel.The invention relates to a closure for plastic infusion solution bags.

Plastikinfusionslösungsbeutel sind an sich bekannt und dienen der Aufbewahrung von zu infundierenden Lösungen und bestehen gewöhnlich aus einem flexiblen Plastikmaterial, das klarsichtig sein soll, damit eventuelle Trübungen der darin befindlichen Lösungen, die ein Anzeichen für nicht mehr einwandfreies Füllgut sein können, sichtbar sind.Plastic infusion solution bags are known per se and are used for the storage of solutions to be infused and usually consist of a flexible plastic material which is intended to be transparent so that any cloudiness of the solutions therein, which can be a sign of contents which are no longer perfect, can be seen.

Derartige Infusionslösungsbeutel müssen dicht und steril verschlossen sein, und das Verschlußmaterial muß derart sein, daß es von einem Infusionsgerät durchstochen werden kann.Such infusion solution bags must be sealed tightly and sterile, and the sealing material must be such that it can be pierced by an infusion device.

Bisher für diesen Zweck verwendete Verschlüsse bestanden beispielsweise aus einem Stopfen aus einem elastisehen Material, wie beispielsweise in DIN 58 366 Blatt 2 für Infusionsflaschen beschrieben, der mit einem Bördelverschluß wie in DIN 58 363 Blatt 3 beschrieben gesichert ist.Closures previously used for this purpose consisted, for example, of a stopper made of an elasti see material as described for example in DIN 58 366 sheet 2 for infusion bottles, which is secured with a crimp closure as described in DIN 58 363 sheet 3.

Der Stopfen selbst sitzt gewöhnlich auf einem konischen oder zylindrischen Anschlußstück, das in die öffnung des Infusionslösungsbeutels eingeklebt oder eingesteckt ist.The stopper itself usually sits on a conical or cylindrical connector that is glued or inserted into the opening of the infusion solution bag.

Derartige Stopfenlassen sich zwar zum Wiederverschließen von Infusionslösungsbeuteln verwenden, besitzen jedoch den Nachteil, daß sie mit der Lösung in Berührung kommen und an dieselbe Füllstoffe, wie sie in Gummi oder Kautschuk enthalten sind oder andere Partikel abgeben können. Bei Verwendung von inerteren Stopfenmaterialien wie beispielsweise Ethylen-Propylen-Copolymere stellt sich dagegen das Problem, daß diese Materialien bei dem gewöhnlich relativ geringen Durchmesser des Einstichteils nicht elastisch genug sind, dadurch beim Einstich des Infusionsgerätes zerreißen und unter Umständen nicht genügend abdichten. Außerdem ist die Einstichfläche des nur durch herkömmlichen Bördelverschluß abgedichteten Stopfens nicht steril, und schließlich bietet ein nur eingeklebtes oder eingestecktes Anschlußstück keine Garantie für absolute Dichtigkeit.Such stoppers can be used to reclose infusion solution bags, but they have the disadvantage that they come into contact with the solution and give off the same fillers as are contained in rubber or rubber or can give off other particles. When using inert plug materials such as ethylene-propylene copolymers, on the other hand, the problem arises that these materials are not elastic enough with the usually relatively small diameter of the puncture part, and thus tear when the infusion device is punctured and under certain circumstances do not seal sufficiently. In addition, the puncture surface of the stopper, which is only sealed by a conventional crimp closure, is not sterile, and, finally, a connector that is only glued or inserted does not guarantee absolute tightness.

Eine weitere bisher bekannte Verschlußart für Infusionslösungsbeutel sind Membranverschlüsse. Hier ist einfach in das Anschlußstück des Beutels eine Membran, digaus dem gleichen Material wie Beutel und/oder Anschlußstück sein kann, eingeschweißt bzw. geklebt.Another previously known type of closure for infusion solution bags are membrane closures. Here, a membrane is simply welded or glued into the connection piece of the bag, which can be made of the same material as the bag and / or connection piece.

Ein solcher Verschluß ist zwar weitestgehend dicht, jedoch kann nach Entfernen des Infusionsgerätes der Beutel nicht wieder abgedichtet bzw. verschlossen werden.Such a closure is largely sealed, but the pouch cannot be sealed or closed again after the infusion device has been removed.

Schließlich sind noch sogenannte Bottle-Pack-Flaschen bekannt, bei denen Flasche und Flaschenhals zwar aus einem Stück sind, also das Problem einer eventuellen Undichtigkeit, wie bei einem eingeklebten oder eingesteckten Anschlußstück entfällt.Finally, so-called bottle-pack bottles are also known, in which the bottle and the bottle neck are made of one piece, so the problem of a possible leakage, as with a glued-in or plug-in connector, is eliminated.

Jedoch können derartige Flaschen aus fertigungstechnischen Gründen bis heute nicht aus einem klarsichtigen Material wie beispielsweise PVC hergestellt werden, sondern sind aus mehr oder weniger trübem Material wie Polyethylen oder Polypropylen und sind außerdem nicht auf die für eine einwandfreie Sterilisierung erforderliche Temperatur (ca. 121°C) zu erhitzen.However, for manufacturing reasons, such bottles cannot be made from a clear material such as PVC, but are made of more or less cloudy material such as polyethylene or polypropylene and are also not at the temperature required for proper sterilization (approx. 121 ° C ) to heat.

Aufgabe der Erfindung war es deshalb, einen Verschluß für einen klarsichtigen Plastikinfusionslösungsbeutel zu schaffen, der die Vorteile des Stopfenverschlusses mit den Vorteilen des Membranverschlusses vereinigt und deren Nachteile ausschließt.The object of the invention was therefore to provide a closure for a clear plastic infusion solution bag, which combines the advantages of the stopper closure with the advantages of the membrane closure and excludes their disadvantages.

Diese Aufgabe konnte mit Hilfe des neuen Verschlusses für einen Plastikinfusionslösungsbeutel gelöst werden, der gekennzeichnet ist durch einen hohlförmigen Konus (1), bestehend aus Konushals (2) und Konuskopf (3), eine im Konuskopf sich befindliche Membran (4), eine über der Membran sich befindliche, aus einem elastischen Material bestehende Scheibe (5) gegebenenfalls mit Aussparung (Durchstichmarkierung) (6) und einen diescheibe 15) dicht verschließenden Deckel (7) mit Aufreißvorrichtung (8).This task could be solved with the help of the new closure for a plastic infusion solution bag, which is characterized by a hollow cone (1) consisting of a cone neck (2) and a cone head (3), a membrane (4) in the cone head, one above the Membrane located, made of an elastic material disc (5), optionally with a recess (puncture mark) (6) and a sealing disc 15) tightly closing lid (7) with tearing device (8).

Die erfindungsgemäße Kombination aus Konus, Membran, Scheibe aus elastischem Material und aufreißbarem Deckel besitzt folgende Vorteile:

  • Absolut dichter Verschluß durch Verschweißen der Einzelteile des Verschlusses untereinander und mit dem Beutel;
  • Sterilisierbarkeit des Verschlußes im strömenden Wasserdampf bei 121°C für 20 Minuten;
  • Sterilität aller unter der Abreißfläche liegenden Teile und damit auch der Einstichfläche für Infusionsgeräte bzw. Kanülen nach Autoklavierung des Systems; Wiederabdichten des Verschlusses nach Herausziehen des Infusionsgerätes;
  • schnelles und problemloses öffnen; Verwendung weitgehend inerten Materials bei allen mit der Infusionslösung in direktem Kontakt stehenden Teilen des Verschlusses.
The combination of cone, membrane, disc made of elastic material and tear-open cover according to the invention has the following advantages:
  • Absolutely tight closure by welding the individual parts of the closure to one another and to the bag;
  • Sterilizability of the closure in flowing water vapor at 121 ° C for 20 minutes;
  • Sterility of all parts lying under the tear-off area and thus also the puncture area for infusion devices or cannulas after the system has been autoclaved; Resealing the closure after pulling out the infusion device;
  • quick and easy opening; Use of largely inert material on all parts of the closure that are in direct contact with the infusion solution.

Bei einer bevorzugten Ausführungsform des Verschlusses bildet die Membran (4) den Bodeneines Napfes (9), der in den Konuskopf (3) eingepaßt ist, wobei die Scheibe (5) wiederum über der Membran in diesen Napf eingepaßt ist.In a preferred embodiment of the closure, the membrane (4) forms the bottom of a bowl (9) which is fitted into the conical head (3), the disk (5) again being fitted into this bowl above the membrane.

Diese Ausführungsform besitzt den zusätzlichen Vorteil, daß der-Beutel durch den Konus, der zuvor mit dem Beutel verschweißt worden ist, mit der Infusionslösung gefüllt werden kann, wobei der Napf mit Membran, elastischer Scheibe und Deckel nachträglich eingeschweißt wird. Wenn die Membran dagegen fest mit dem Konus verbunden ist, ist eine zweite Einfüllöffnung im Beutel erforderlich, die bei der bevorzugten Ausführungsform entfällt.This embodiment has the additional advantage that the bag can be filled with the infusion solution through the cone, which has previously been welded to the bag, the cup with the membrane, elastic disc and cover being subsequently welded in. If, on the other hand, the membrane is firmly connected to the cone, a second filling opening in the bag is required, which is omitted in the preferred embodiment.

Ein weiterer Vorteil der bevorzugten Ausführungsform besteht darin, daß Napf mit Membran, elastischer Scheibe und Deckel eine vorgefertigte Einheit bilden können, die nach dem Füllen des Beutels in den Konuskopf eingeschweißt wird.Another advantage of the preferred embodiment is that the bowl with membrane, elastic disc and cover can form a prefabricated unit which is welded into the cone head after the bag has been filled.

Die absolute Dichtigkeit des Verschlusses wird durch Verschweißung, zunächst des Deckels mit dem Napf, mit dazwischenliegender Gummischeibe, und dann mit dem Konus erreicht. Der Konushals wiederum ist vorteilhafterweise durch Schweißung mit dem Beutel verbunden. Die Verschweißung, als sicherste Art, zwei Teile miteinander zu verbindene ist deshalb möglich, weil Napf, Deckel und Konus aus miteinander verschweißbarem Material gefertigt sind. Der Verschluß enthält also im Gegensatz zu anderen Systemen keine Steck- oder Klebeverbindungen.The absolute tightness of the closure is achieved by welding, first the cover with the bowl, with the rubber washer in between, and then with the cone. The cone neck in turn is advantageously connected to the bag by welding. Welding, as the safest way to connect two parts to one another, is possible because the bowl, lid and cone are made of material that can be welded together. In contrast to other systems, the closure does not contain any plug-in or adhesive connections.

Die für den Verschluß geeigneten Materialien (z.B. PVC, Gummi) können im strömenden Wasserdampf bei 121°C sterilisiert werden.The materials suitable for the closure (e.g. PVC, rubber) can be sterilized in flowing steam at 121 ° C.

Die Einstichfläche auf der elastischen Scheibe liegt unter demmit dem Napf verschweißten Deckel. Die Wasserdampfdurchlässigkeit des gewählten Kunststoffes garantiert, daß die Oberfläche der Gummischeibe bei der Sterilisation des verschlossenen Behältnisses im strömenden Wasserdampf ebenfalls keimfrei wird und bis zur Anwendung bleibt.The puncture surface on the elastic disc lies under the cover welded to the bowl. The water vapor permeability of the selected plastic guarantees that the surface of the rubber washer is also germ-free during the sterilization of the sealed container in the flowing water vapor and remains until use.

In einer besonderen Ausführungsform kann die elastische Scheibe eine Art Hohlstopfen bildende Verlängerung aufweisen, die in den Konuskopf (3) hineinragt und fest an dessen Seitenwänden anliegt. Dabei kann der Durchmesser des eigentlichen Scheibenteils etwas größer sein als der des Hohlstopfenteils, so daß die Scheibe nicht, wie in den Figuren gezeigt, im Konuskopf, sondern bündig auf demselben sitzt.In a special embodiment, the elastic disk can have a kind of extension that forms hollow plugs, which protrudes into the conical head (3) and lies firmly against the side walls thereof. The The diameter of the actual disk part may be somewhat larger than that of the hollow plug part, so that the disk does not sit in the conical head, as shown in the figures, but flush on the same.

Bei dieser Ausführungsform ist der die Scheibe (5) dicht verschließende Deckel (7) mit Aufreißvorrichtung (8) vorzugsweise als gebördelter Metalldeckel ausgebildet, der den auf dem Konuskopf sitzenden Scheibenteil und die oberste Stufe des stufenförmig ausgebildeten Konuskopfs umfaßt.In this embodiment, the cover (7) which seals the disc (5) with a tear-open device (8) is preferably designed as a flanged metal cover which comprises the disc part sitting on the cone head and the uppermost step of the step-shaped cone head.

Aufgrund der Tatsache, daß die elastische Scheibe nicht direkt mit der Infusionslösung in Kontakt steht, sondern durch die Membran getrennt ist, ist es möglich, als Material für die Scheibe hochelastischen Naturkautschuk zu verwenden. Die Verwendung hochelastischen Materials ist deshalb besonders erwünscht, weil nach Entfernen des Infusionsgerätes eine bessere Wiederabdichtung als bei einem weniger, elastischen Material gegeben ist.Due to the fact that the elastic disc is not in direct contact with the infusion solution, but is separated by the membrane, it is possible to use highly elastic natural rubber as the material for the disc. The use of highly elastic material is particularly desirable because after removal of the infusion device, there is better resealing than with a less elastic material.

Unter dem Begriff Konus im vorliegenden Sinne wird ein abgestumpfter Stufen-Konus verstanden, wobei die Stufe. mit dem geringsten Durchmesser den Konushals und die übrigen Stufen den Konuskopf bilden.The term cone in the present sense means a truncated step cone, the step. form the cone neck with the smallest diameter and the remaining steps form the cone head.

Der Konushals kann zylindrisch ausgebildet sein, kann jedoch selbst etwas konisch verlaufen.The cone neck can be cylindrical, but can itself be somewhat conical.

Obgleich Naturkautschuk das optimale Stopfenmaterial ist, können im Rahmen der vorliegenden Erfindung auch andere Gummi- oder Kautschukarten wie Chlorbutylkautschuk oder andere Elastomere verwenet werden.Although natural rubber is the optimal plug material, other types of rubber or rubbers such as chlorobutyl rubber or other elastomers can also be used in the context of the present invention.
