A cap (17) joined to the tube covers the seal and has a main body (18) possessing an opening (27,39) covered by a tear-off closure piece. A lid (24) on the tube, the main cap body or the closure piece, may be placed onto the main cap body when the closure piece is torn off. A base piece (12) may be weldable to the bag and have, at least, two tubes each possessing a radial flange (50) on which the rim of the main cap body rests. The tube can have radially sprung arm fittings (34) from the interior of the cap into detents in the main cap body.

Description

Die Erfindung betrifft ein Portsystem für Beutel, die Flüssigkeiten für medizinische Anwendungen enthalten, also Flüssigkeiten für Infusionen, klinische Ernährung oder Dialyse oder Spüllösungen.The invention relates to a port system for bags which contain liquids for medical applications, that is to say liquids for infusions, clinical nutrition or dialysis or rinsing solutions.

Ein Portsystem, von dem der Oberbegriff des Patentanspruchs 1 ausgeht, ist bekannt aus WO92/00118. Bei diesem Portsystem sind an einem Beutel zwei abstehende Rohre befestigt, von denen das eine einen Entnahmeport und das andere einen Additionsport bildet. Jedes dieser Rohre ist durch eine Membran verschlossen, die von dem Einstechdorn eines Übertragungsgerätes oder der Nadel einer Spritze durchstochen werden kann. Auf jedem Rohr sitzt eine Kappe, die aus einem Kappenkörper und einem abreißbaren Verschlußteil besteht. Diese Kappe ist abdichtend auf dem Rohr befestigt und sie bedeckt die Membran vollständig, so daß diese von der Kappe und dem Rohr keimdicht umschlossen wird. Nach dem Abreißen des Verschlußteils liegt der Durchstechbereich der Membranfläche frei. Die Membran kann somit durchstochen werden, um mit einem Übertragungsgerät Zugang zu dem Innern des Beutels zu erhalten.A port system, from which the preamble of claim 1 is based, is known from WO92 / 00118. In this port system, two protruding tubes are attached to a bag, one of which forms a removal port and the other an addition port. Each of these tubes is closed by a membrane which can be pierced by the spike of a transmission device or the needle of a syringe. A cap, which consists of a cap body and a tear-off closure part, sits on each tube. This cap is sealingly attached to the tube and it completely covers the membrane, so that the cap and the tube enclose it in a germ-tight manner. After the closure part has been torn off, the piercing area of the membrane surface is exposed. The membrane can thus be pierced to access the inside of the bag with a transmitter.

Der Erfindung liegt die Aufgabe zugrunde, ein verbesserte Portsystem für einen Beutel zu schaffen, um die Sicherheit der Verwendung des Beutels zu erhöhen.The invention has for its object to provide an improved port system for a bag in order to increase the safety of the use of the bag.

Die Lösung dieser Aufgabe erfolgt erfindungsgemäß mit den im Patentanspruch 1 angegebenen Merkmalen.This object is achieved according to the invention with the features specified in claim 1.

Bei dem erfindungsgemäßen Portsystem ist ein Deckel vorhanden, der nach dem Abreißen des Verschlußteils auf den Kappenkörper aufgesetzt wird und dessen Zugangsöffnung verschließt. Der Deckel ist an dem Rohr, dem Kappenkörper oder dem Verschlußteil befestigt. Der Deckel ist daher ein unverlierbares Teil, das mit dem betreffenden Port eine Einheit bildet und nicht verlorengehen kann. Der Deckel erfordert auch keine selbständige Entsorgung, sondern er wird mit dem gesamten Portsystem, nachdem dieses benutzt worden ist, entsorgt.In the port system according to the invention there is a cover which is placed on the cap body after the closure part has been torn off and closes its access opening. The lid is attached to the tube, the cap body or the closure part. The cover is therefore a captive part that forms a unit with the port in question and cannot be lost. The lid does not require independent disposal either, but is disposed of with the entire port system after it has been used.

Vorzugsweise ist der Deckel so ausgebildet, daß er nach dem Aufsetzen auf den Kappenkörper an diesem verriegelt ist und nicht entfernt werden kann, ohne daß dies durch eine Beschädigung des Deckels oder des Kappenkörpers sichtbar ist.The lid is preferably designed such that after being placed on the cap body it is locked to it and cannot be removed without this being visible through damage to the lid or the cap body.

Dadurch, daß die Zugangsöffnung des Kappenkörpers durch einen Deckel bleibend verschlossen wird, wird im Falle des Additionsports erreicht, daß das Zuspritzen eines Medikaments zu dem Beutelinhalt nur im unmittelbaren Anschluß an das Öffnen des Additionsports möglich ist. Nach erfolgtem Injizieren eines oder mehrerer Medikamente verschließt der Benutzer den Additionsport mit dem Deckel, der nicht, ohne daß dies von außen erkennbar wäre, wieder gelöst werden kann. Damit wird erreicht, daß der Benutzer ein Medikament nur einmal zuspritzen kann, und nicht etwa eine zweimalige Zuspritzung durchführt, weil er zwischenzeitlich abgelenkt worden ist und die erste Zuspritzung vergessen hat. Ferner wird sichergestellt, daß kein Dritter irgendwelche Substanzen durch den Additionsport in den Beutel unbemerkt einführt.Because the access opening of the cap body is permanently closed by a lid, in the case of the addition port it is achieved that the injection of a medicament into the contents of the bag is only possible immediately after the opening of the addition port. After injecting one or more drugs the user closes the addition port with the lid, which cannot be released again without this being recognizable from the outside. The result of this is that the user can only inject a medication once and does not, for example, carry out a double injection because he has been distracted in the meantime and has forgotten the first injection. It also ensures that no third party introduces any substances into the bag unnoticed through the addition port.

Generell ist der Deckel für einen Additionsport vorgesehen, jedoch kann auch ein Entnahmeport, durch den Flüssigkeit aus dem Beutel entnommen wird, in der erfindungsgemäßem Weise ausgebildet sein. Der Entnahmeport wird nach der erstmaligen Entnahme mit einem Deckel verschlossen. Dies ist beispielsweise dann sinnvoll, wenn der Beutelinhalt sofort nach dem Öffnen des Beutels verbraucht werden muß und ein im Beutel noch enthaltener Rest danach nicht mehr verwendet werden darf.The lid is generally provided for an addition port, but a removal port through which liquid is removed from the bag can also be designed in the manner according to the invention. The removal port is closed with a lid after the first removal. This is useful, for example, if the contents of the bag have to be used up immediately after opening the bag and a residue that is still contained in the bag may not be used afterwards.

Vorzugsweise ist das Portsystem mit mindestens zwei Rohren ausgestattet, von denen eines zu einem Entnahmeport und das andere zu einem Additionsport gehört. Die beiden Rohre bilden zusammen mit einem Basisteil eine einstückige Einheit. Das Basisteil wird mit der Beutelwandung abdichtend verschweißt. Das gesamte Portsystem besteht aus nur sehr wenigen Komponenten, nämlich dem Basisteil mit den daran befindlichen Rohren, den auf den Enden der Rohre aufgesetzen Kappen und den zwischen den Kappen und den Rohren eingspannten Membranen. Bei zwei Ports sind also insgesamt nur drei Kunststoffteile nötig, nämlich die Basisteile mit den Rohren und die Kappen mit den ihnen angeformten Verschlußteilen. Die Deckel sind entweder demjenigen Teil angeformt, zu dem die Rohre gehören, oder den einzelnen Kappen bzw. deren Verschlußteilen.The port system is preferably equipped with at least two tubes, one of which belongs to a removal port and the other to an addition port. The two tubes form a one-piece unit together with a base part. The base part is sealed to the bag wall. The entire port system consists of very few components, namely the base part with the tubes attached to it, the caps placed on the ends of the tubes and the membranes clamped between the caps and the tubes. With two ports there are only three plastic parts necessary, namely the base parts with the tubes and the caps with the molded closure parts. The covers are either molded onto the part to which the pipes belong, or the individual caps or their closure parts.

Im folgenden werden Ausführungsbeispiele der Erfindung unter Bezugnahme auf die Zeichnungen näher erläutert.Exemplary embodiments of the invention are explained in more detail below with reference to the drawings.

Bei dem Ausführungsbeispiel der Fign. 1-3 ist an einem aus Kunststoff bestehenden Beutel 10, der eine für den medizinischen Einsatz bestimmte steril verschlossene Flüssigkeit enthält, das Portsystem 11 vorgesehen, das an den Beutel 10 angeschweißt ist. Zu diesem Zweck enthält das Fortsystem ein Basisteil 12 mit mehreren parallelen Rippen, deren Breite sich zu den Enden hin verringert, so daß das Basisteil 12 die Form eines Schiffchens hat. An die Rippen des Basisteils 12 werden von außen her die Beutelwandungen angeschweißt, so daß das Basisteil 12 den Beutel abdichtend verschließt. Von dem Basisteil 12 ragen zwei Rohre 13,14 parallel zueinander nach außen. Das Rohr 13 ist Bestandteil des Entnahmeports 15 und das Rohr 14 ist Bestandteil des Additionsports 16. Auf jedem Rohr sitzt eine Kappe 17. Die beiden Kappen 17 sind einander gleich. Jede Kappe 17 besteht aus einem Kappenkörper 18 und einem diesem einstückig angeformten Verschlußteil 19. Der Kappenkörper 18 hat die Form einer Glocke. Er sitzt mit seinem unteren Rand auf einem vom Rohr 14 abstehenden Flansch 50 auf. Auf der Oberwand 20 des Kappenkörpers 18 sitzt das Verschlußteil 19. Dieses Verschlußteil ist nach Art eines umgekehrten Bechers ausgebildet, dessen Rand über eine Schwächungslinie 21 in die Oberwand 20 des Kappenkörpers 18 übergeht. Das Verschlußteil 19 ist ferner mit abstehenden Flügeln 22 zum Angreifen der Hand versehen.In the embodiment of FIGS. 1-3, the port system 11 is provided on a bag 10 made of plastic, which contains a sterile sealed liquid intended for medical use, which is welded to the bag 10. For this purpose, the continuation system contains a base part 12 with several parallel ribs, the width of which decreases towards the ends, so that the base part 12 has the shape of a boat. The bag walls are welded to the ribs of the base part 12 from the outside, so that the base part 12 seals the bag in a sealing manner. Two tubes 13, 14 protrude from the base part 12 parallel to one another outwards. The tube 13 is part of the removal port 15 and the tube 14 is part of the addition port 16. A cap 17 sits on each tube. The two caps 17 are identical to one another. Each cap 17 consists of a cap body 18 and a closure part 19 integrally molded thereon. The cap body 18 has the shape of a bell. It sits with its lower edge on a flange 50 projecting from the tube 14. The closure part 19 is seated on the top wall 20 of the cap body 18. This closure part is designed in the manner of an inverted cup, the edge of which merges into the top wall 20 of the cap body 18 via a line of weakness 21. The closure member 19 is also provided with projecting wings 22 for attacking the hand.

Gemäß Fig. 1 ist dem zum Rohr 14 gehörenden Flansch 50 eine flexible Lasche 23 mit einem Deckel 24 angeformt. Der Deckel 24 ist so ausgebildet, daß er über die Oberwand 20 des Kappenkörpers 18 gesetzt werden kann und sich dann mit Rastelementen 25 an dem Rand 26 derart verhakt, daß er zerstörungsfrei nicht mehr von dem Kappenkörper 18 abgenommen werden kann.1, the flange 50 belonging to the tube 14 is formed with a flexible tab 23 with a cover 24. The cover 24 is designed such that it can be placed over the top wall 20 of the cap body 18 and then hooked to the edge 26 with locking elements 25 such that it can no longer be removed from the cap body 18 without being destroyed.

Dieser Zustand ist in Fig. 2 dargestellt. Hier ist die durch das Abdrehen des Verschlußteils 19 freigelegte Öffnung in der Stirnwand 20 des Kappenteils 18 mit dem aufgesetzten Deckel 24 verschlossen. Die Stirnwand 20 des Entnahmeports 15 liegt dagegen frei. Von ihr ist das zugehörige Verschlußteil 19 abgedreht worden, so daß nur noch die Abreißlinie 51 verblieben ist, die die freigelegte Durchtrittsöffnung 27 umgibt. Die Durchtrittsöffnung 27 enthält Verriegelungselemente 28 in Form von Bajonettverschluß-Schlitzen.This state is shown in Fig. 2. Here, the opening in the end wall 20 of the cap part 18, which is exposed by turning off the closure part 19, is closed with the cover 24 attached. The end wall 20 of the removal port 15, however, is exposed. The associated closure part 19 has been unscrewed from it, so that only the tear line 51 remains, which surrounds the exposed passage opening 27. The passage opening 27 contains locking elements 28 in the form of bayonet lock slots.

Fig. 3 zeigt, daß in die Durchtrittsöffnung 27 des Entnahmeports 15 der Einstechdorn 30 eines Übertragungsgerätes 31 eingesteckt worden ist. An dem Einstechdorn 30 befinden sich Gegen-Verriegelungselemente 29, die mit den Verriegelungselementen 28 den Bajonettverschluß bilden. Dabei wird der Einstechdorn 30 zunächst axial in den Entnahmeport eingesteckt und anschließend gedreht, wodurch er gegen axiales Herausziehen gesichert ist.3 shows that the piercing mandrel 30 of a transmission device 31 has been inserted into the passage opening 27 of the removal port 15. On the spike 30 there are counter-locking elements 29 which form the bayonet lock with the locking elements 28. The piercing mandrel 30 is first inserted axially into the removal port and then rotated, whereby it is secured against axial pulling out.

Wie aus Fig. 3 ferner hervorgeht, befindet sich im Innern des Kappenkörpers 28 ein selbstschließendes Dichtungselement in Form einer gummielastischen Membran 32, die von ringförmigen axialen Stegen 33,34 des Rohres 13 und des Kappenkörpers 18 ringförmig abgestützt ist. Festgehalten wird der Kappenkörper 18 auf dem Rohr 13 durch Arme 34, die von dem Flansch 50 axial nach außen abstehen und radial federn können. An den Enden dieser Arms 34 befinden sich nach außen weisende Nasen 35, die entsprechend in Ausnehmungen der Umfangswand des Kappenkörpers 18 einrasten. Auf diese Weise kann der Kappenkörper 18 auf dem Rohr 13 durch einfaches Aufschieben montiert werden. Der Umfangsrand der Membran 32 drückt von innen her gegen die Arme 34 und drückt somit die Nasen 35 elastisch nach außen. Die Nasen 35 dienen auch dazu, den Kappenkörper 18 während des Abdrehens des Verschlußteils 19 verdrehungssicher festzuhalten.As can also be seen from FIG. 3, there is a self-closing sealing element in the form of a rubber-elastic membrane 32 inside the cap body 28, which is supported in a ring shape by annular axial webs 33, 34 of the tube 13 and the cap body 18. The cap body 18 is held on the tube 13 by arms 34 which project axially outwards from the flange 50 and can spring radially. At the ends of these arms 34 there are outwardly facing lugs 35, which correspondingly snap into recesses in the peripheral wall of the cap body 18. In this way, the cap body 18 can be mounted on the tube 13 by simply sliding it on. The peripheral edge of the membrane 32 presses against the arms 34 from the inside and thus presses the lugs 35 elastically outwards. The lugs 35 also serve to hold the cap body 18 against rotation during the twisting off of the closure part 19.

Der innere Aufbau des Additionsports 16 ist im wesentlichen gleich demjenigen des Entnahmeports 15. Unterschiedlich ist, daß im Addtionsport 16 das Dichtungselement 38 unmittelbar unter der Stirnwand 20 angeordnet ist und eine in der Stirnwand 20 vorgesehene Durchtrittsöffnung 39 ausfüllt. Das Dichtungselement 38 liegt also nach dem Abdrehen des Verschlußteils 19 in der Oberfläche der Stirnwand 20 frei, damit es mit einer Hohlnadel durchstochen werden kann.The internal structure of the addition port 16 is essentially the same as that of the removal port 15. The difference is that in the addition port 16 the sealing element 38 is arranged directly under the end wall 20 and fills a passage opening 39 provided in the end wall 20. The sealing element 38 is thus exposed after the closure part 19 has been unscrewed in the surface of the end wall 20 so that it can be pierced with a hollow needle.

Bei beiden Ports ist der Übergang von dem Rohr 13,14 in den radialen Flansch 50 kelchförmig gestaltet, um eine Fingerstützfläche zu bilden, an der das Rohr mit Daumen und Zeigefinger ergriffen werden kann. Der Durchmesser des Kappenkörpers ist mindestens 1 cm größer als derjenige des Rohres, so daß der Kappenkörper einen Schutzschild für die unter ihm am Rohr angreifenden Finger bildet. Der Innendurchnesser des Rohres 13 ist entsprechend dem Außendurchmesser des Einstechdornes 30 relativ groß, während das Rohr 14 einen geringeren Durchmesser hat, um den Portraum zu minimieren. Beide Rohre 13,14 führen durch das Basisteil 12 hindurch und münden in den Beutel 10 ein.In both ports, the transition from the tube 13, 14 into the radial flange 50 is designed in a goblet shape in order to form a finger support surface on which the tube can be gripped with the thumb and forefinger. The diameter of the cap body is at least 1 cm larger than that of the tube, so that the cap body forms a protective shield for the fingers attacking the tube below it. The inner diameter of the tube 13 is relatively large in accordance with the outer diameter of the piercing mandrel 30, while the tube 14 has a smaller diameter in order to minimize the port space. Both tubes 13, 14 lead through the base part 12 and open into the bag 10.

Bei dem Ausführungsbeispiel der Fign. 4 und 5 ist das Basisteil 12 und die Rohre 13,14 in gleicher Weise ausgestaltet wie beim ersten Ausführungsbeispiel. Die Kappen 17a unterscheiden sich von den Kappen 17 des ersten Ausführungsbeispiels nicht im Hinblick auf die Kappenkörper 18, sondern nur im Hinblick auf die Verschlußteile 19a, denen jeweils ein Deckel 24a einstückig angeformt ist. Die Verschlußteile 19 bestehen hier aus jeweils einem Rohrstutzen, der durch eine seitlich abstehende Platte 40 verschlossen ist. Diese Platte ist zugleich Bestandteil des Deckels 24a. Um die Platte 24 herum erstreckt sich ein dem Rohrstutzen abgewandter Rastrand 41 mit Rastelementen 42, die unlösbar mit dem Rand 26 des Kappenkörpers 18 zusammengreifen, wenn sie über diesen Rand überschnappen.In the embodiment of FIGS. 4 and 5, the base part 12 and the tubes 13, 14 are configured in the same way as in the first exemplary embodiment. The caps 17a differ from the caps 17 of the first exemplary embodiment not with regard to the cap bodies 18, but only with regard to the closure parts 19a, each of which has a cover 24a formed integrally thereon. The closure parts 19 each consist of a pipe socket, which is closed by a laterally protruding plate 40. This plate is also part of the lid 24a. Around the plate 24 there extends a latching edge 41 facing away from the pipe socket with latching elements 42 which inextricably engage with the rim 26 of the cap body 18 when they snap over this rim.

Fig. 5 zeigt, wie das kombinierte Verschlußteil 19a mit Deckel 24a von der Stirnwand des Kappenkörpers 18 des Additionsports 16 abgedreht wurde, um umgekehrt (d.h. mit dem Deckel 24a) auf den Kappenkörper 18 aufgesetzt zu werden. Der Abreißrand, an dem das Verschlußteil 19 abgerissen ist, ist in Fig. 5 mit 43 bezeichnet.FIG. 5 shows how the combined closure part 19a with lid 24a was twisted off the end wall of the cap body 18 of the addition port 16 in order to be placed on the cap body 18 in reverse (ie with the lid 24a). The tear-off edge on which the closure part 19 is torn is designated 43 in FIG. 5.

Der Rastrand 41 ist mit Unterbrechungen 44 versehen, die sich bis in die Scheibe 41 erstrecken und dazu dienen, besser mit der Hand angreifen zu können, wenn das Verschlußteil von dem Kappenkörper 18 abgedreht wird.The locking edge 41 is provided with interruptions 44 which extend into the disk 41 and serve to be able to better grip by hand when the closure part is unscrewed from the cap body 18.

Bei dem Ausführungsbeispiel der Fign. 6-8 ist ebenfalls das Verschlußteil 19b mit dem Deckel 24b zu einem einzigen Bauteil vereinigt. Dieses Bauteil weist eine Scheibe 46 auf, an deren einer Seite das Verschlußteil 19b in Form eines liegenden Rohrstutzens angeordnet ist (Fig. 8), während zur gegenüberliegenden Seite der Rastrand 46 absteht, der mit dem Rand 26 des Kappenkörpers 18 unlösbar verrastet wird.In the embodiment of FIGS. 6-8, the closure part 19b is also combined with the cover 24b to form a single component. This component has a disk 46, on one side of which the closure part 19b is arranged in the form of a lying pipe socket (FIG. 8), while on the opposite side the latching edge 46 protrudes, which is permanently locked to the edge 26 of the cap body 18.
