Abstract
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 that Contain liquids for medical applications, i.e. liquids for infusions, clinical nutrition or dialysis or irrigation 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, of which the preamble of the claim 1 is known from WO92 / 00118. At This port system has two protruding parts on one bag Pipes attached, one of which has a removal port and the other forms an addition port. Any of these Pipe is closed by a membrane that is covered by the Spike of a transmission device or the needle a syringe can be pierced. On every pipe sits a cap that consists of a cap body and a tearable closure part exists. This cap is sealing attached to the pipe and it covered the Membrane completely so that this from the cap and the Tube is enclosed in a germ-tight manner. After tearing off the Closure part is the piercing area of the membrane surface free. The membrane can thus be pierced to access the interior with a transmission device of the bag.
Aus FR-A-2 291 109 ist ein Portsystem für medizinische Beutel bekannt, das ebenfalls dem Oberbegriff des Patentanspruchs 1 entspricht. Ferner ist an dem Verschlußteil und an dem Kappenkörper ein Stopfen vorgesehen, der nach dem Abreißen des Verschlußteils in die dann geöffnete Durchtrittsöffnung eingedrückt werden kann und diese verschließt. Das Dichtungselement besteht dabei aus einer zum Rohr gehörenden Zwischenwand, die nach dem Durchstechen nicht selbstdichtend ist. Die Kappe ist an das äußere Ende des Rohres unter Verwendung eines Lösungsmittels angeschweißt.From FR-A-2 291 109 is a port system for medical Bag known, which is also the preamble of the claim 1 corresponds. Furthermore, is on the closure part and a stopper is provided on the cap body, who after tearing off the closure part in the then opened passage opening are pressed in can and seals them. The sealing element is made thereby from a partition wall belonging to the pipe, which is not self-sealing after piercing. The Cap is using to the outer end of the tube of a solvent welded on.
Der Erfindung liegt die Aufgabe zugrunde, ein Portsystem für einen Beutel mit hoher Verwendungssicherheit zu schaffen, das einfach montiert werden kann. The invention has for its object a port system for a bag with a high level of safety to create that can be easily assembled.
Die Lösung dieser Aufgabe erfolgt erfindungsgemäß mit den im Patentanspruch 1 angegebenen Merkmalen.This object is achieved with the invention 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 present, which after tearing off the closure part the cap body is placed and its access opening closes. The lid is on the tube, the cap body or the closure part attached. The lid is therefore a captive part that is related to that Port forms a unit and is not lost can. The lid also does not require independent disposal, but with the entire port system, after it has been used, disposed of.
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.Preferably, the lid is designed so that after locked on the cap body locked on this is and cannot be removed without this damage to the lid or cap body is visible.
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.The fact that the access opening of the cap body through a lid is permanently closed in the case of the addition port achieved that the injection of a Drug to the contents of the bag only in the immediate Connection to the opening of the addition port is possible. After injecting one or more drugs the user closes the addition port with the lid, which is not recognizable from the outside would be solved again. So that is achieved that the user inject a drug only once can, and not a double injection performs because he is distracted in the meantime and has forgotten the first injection. It also ensures that no third party Substances through the addition port in the bag introduces unnoticed.
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 Dekkel 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.Generally the cover is intended for an addition port, however, a removal port through which Liquid is removed from the bag in the inventive Be trained. The removal port comes with a lid after the first removal locked. This makes sense, for example, if the bag contents immediately after opening the Bag must be consumed and one in the bag still contained rest can no longer be used afterwards may.
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 at least two Pipes equipped, one of which to a removal port and the other belongs to an addition port. The Both tubes form one together with a base part one-piece unit. The base part comes with the bag wall welded to seal. The entire port system consists of very few components, namely the Base part with the tubes attached to it the ends of the pipes and the between the caps and tubes clamped membranes. At So two ports are only three plastic parts necessary, namely the base parts with the tubes and the Caps with the closure parts molded onto them. The Lids are either molded onto the part to which the tubes belong, or the individual caps or their Closure parts.

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 Portsystem 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 is on one
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 is the
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 is the
exposed by turning off the
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. Fig. 3 shows that in the passage opening 27 of the
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 is also apparent from Fig. 3, is located inside
of the
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
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.For both ports, the transition from the tube is 13, 14 in
the
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 is that
