Description

Konnektorsystem mit zwei Konnektoren Connector system with two connectors
Die Erfindung betrifft ein Konnektorsystem mit zwei Konnektoren für ein Transfusionssystem.The invention relates to a connector system with two connectors for a transfusion system.
Für Patiententransfusionssysteme z. B. vor Hahnbänken eines Intensivpatienten ist ein schnelles Wechseln der Infusionssysteme bzw. ein einfaches Einspritzen von Medika- menten in den zentralvenösen Zugang erforderlich. Hierfür werden üblicherweise Spritzenaufsätze, Dreiwegehähne, Abdeckkappen für die Endöff ungen etc. verwendet. Diese müssen in mehreren Arbeitschritten getauscht, gewechselt, verschlossen und beschickt werden - oft über Mehrwegehahnsysteme - was durch ungewollte Berührung der Endstücken mit den Fingern, mit Teilen aus der unmittelbaren Umgebung etc. die Keimarmut dieser offener Systems verschlechtert. Das Eindringen ungewollter Luftbläschen in den nicht abgeschlossenen Injektionstrakt ist leicht möglich und die Entlüftung ist nicht unproblematisch.For patient transfusion systems e.g. For example, in front of an intensive care patient's tap banks, a quick change of infusion systems or a simple injection of medication into the central venous access is required. Syringe attachments, three-way taps, cover caps for the end openings, etc. are usually used for this. These have to be exchanged, changed, closed and loaded in several work steps - often via multi-way valve systems - which worsens the low-germ level of this open system due to unwanted touching of the end pieces with the fingers, with parts from the immediate vicinity etc. The penetration of unwanted air bubbles into the incomplete injection tract is easily possible and the ventilation is not without problems.
Aufgabe der Erfindung ist es, eine einfache Norrichtung zu schaffen, die als Bestandteil eines Transfusionssystems eine berärirungsfreie, keimarme/sterile Verbindung zweierThe object of the invention is to provide a simple device which, as part of a transfusion system, provides a non-irritating, low-germ / sterile connection between two

Der Konnektor sitzt als Verbindungsstück zwischen den Schlauchstücken eines Transfusionssystems, z. B. vor Hahnbänken eines Intensivpatienten und dient einem schnellen Wechsel der Infusionssysteme, bzw. einem einfachen Einspritzen von Medikamenten in den zentralvenösen Zugang. Ein Teil befindet sich patientenseitig am zentralvenösen Katheter oder an der Hahnbank (Fig. 2), das Gegenstück (Fig. 1) kommt vom Schlauchsy- stem des zu infundierenden Medikaments oder sitzt auf einer Spritze 11, mit der Flüssigkeiten 17 in das System gegeben werden. Die einzelnen Konnektoren bestehen aus den äußeren Zylindern 1, die mit einem Nerschlusssystem 3 versehen sind und den inneren Irrfusionsröhren 4, 5, 6, 7, die teils arretiert, teils frei beweglich unter mechanischer Spannung mittels Federn 8 gehalten werden.The connector sits as a connector between the tube pieces of a transfusion system, e.g. B. in front of tap banks of an intensive care patient and is used for a quick change of the infusion systems, or a simple injection of medication into the central venous access. A part is located on the patient side on the central venous catheter or on the tap bench (FIG. 2), the counterpart (FIG. 1) comes from the tube system of the medication to be infused or sits on a syringe 11 with which liquids 17 are added to the system , The individual connectors consist of the outer cylinders 1, which are provided with an open circuit system 3, and the inner irrigation tubes 4, 5, 6, 7, which are partly locked and partly freely movable under mechanical tension by means of springs 8.
Der gesamte Konnektor besteht aus zwei äußeren Zylindern 1, die das eigentliche Infusionssystem umschließen. Die Zylinder 1 werden an ihrer Stirnseite mit einem Steckverbinder 2 - vorzugsweise ein Bajonertverschluss - miteinander verbunden. An der Stirnseite eines jeden Zylinders 1 befindet sich jeweils eine Öffnung, die durch einen Lamellenver- schluss 3 abgeschlossen ist. Das eigentliche Infusionssystem besteht aus zwei ineinander verschiebbare Röhren 4, 5 und 6, 7, die sich im Iiinenraum eines jeden Zylinders 1 befin- den. Röhre 4 und Röhre 6 sind vom mechanischen Durchmesser so gearbeitet, dass die Röhre 4 an der Spitze verjüngt ist (Luer- Ansatz) und als Kegelstumpfsich passgerecht in die Röhre 6 bei Betätigung des Transfusionssystems mittels Druckbeaufschlagung 14 einführt. Eine Feder 8, die an der einen Seite mit einem Federlager 9, das mit dem Zylin- der 1 arretiert ist, fest verbunden ist und auf der gegenüberliegenden Seite auf einer runden Scheibe 10 befestigt ist, deren Durchmesser geringfügig kleiner ist als der Innendurchmesser des Zylinders 1 und sich bei Druck 14 auf den Infusionsbehälter 11 gegen die Federkräfte in den Zylinder 1 schiebt.The entire connector consists of two outer cylinders 1, which enclose the actual infusion system. The cylinders 1 are connected to one another on their end face with a plug connector 2 - preferably a bayonet lock. At the end of each cylinder 1 there is an opening, which is closed by a lamella closure 3. The actual infusion system consists of two tubes 4, 5 and 6, 7 which can be pushed into one another and which are located in the internal space of each cylinder 1. the. Tube 4 and tube 6 have a mechanical diameter such that tube 4 is tapered at the tip (Luer approach) and, as a truncated cone, fits into tube 6 when the transfusion system is actuated by means of pressurization 14. A spring 8, which is firmly connected on one side to a spring bearing 9, which is locked with the cylinder 1, and is fastened on the opposite side to a round disk 10, the diameter of which is slightly smaller than the inside diameter of the cylinder 1 and pushes against the spring forces into the cylinder 1 at pressure 14 on the infusion container 11.
Innerhalb des Federraumes befinden sich Stifte 12, die an der inneren, beweglichen Zylinderscheibe 10 befestigt sind, durch Bohrungen im Federlager 9 geführt werden und sich bei Richtungsdruck 14 auf den Infusionsbehälter/Spritze 11 auf die geschlossenen Lamellen 3 zu bewegen (s. Fig. 1, 2) und bei weiterer Drückerhöhung den Lamellenverschluss öffnen (Fig. 3, 3a). Wird der Richtungsdruck soweit erhöht, dass die Endplatte 15, deren Durchmesser etwas größer ist als der Innendurchmesser des Zylinders 1, sich nahe am Zylinderboden befindet, wird die Röhre 5 in die Röhre 4 und die Röhre 7 in die Röhre 6 gedrückt. Die zylindrischen Röhren 5 und 7 sind am Ende durch einen Deckel verschlossen. Unterhalb des Deckelkranzes befindet sich wenigstens eine seitliche Bohrung 13, die vor der Druckausübung von einem flüssigkeitsdichtenden Ring 16 umgeben ist (Fig. 4). Wird der Richtungsdruck soweit erhöht das die Endplatte 15 am Zylinderende anschlägt, dann schieben sich die Röhren 5 und 7 aus ihrer Ringhalterung 16; die Löcher 13 werden freigegeben und die Flüssigkeit 17 kann in beide Richtungen passieren (Fig. 4a).Inside the spring chamber there are pins 12 which are fastened to the inner, movable cylindrical disk 10, are guided through bores in the spring bearing 9 and move at the directional pressure 14 on the infusion container / syringe 11 onto the closed lamellae 3 (see FIG. 1 , 2) and open the slat lock when the pressure is increased further (Fig. 3, 3a). If the directional pressure is increased to such an extent that the end plate 15, the diameter of which is somewhat larger than the inside diameter of the cylinder 1, is close to the cylinder base, the tube 5 is pressed into the tube 4 and the tube 7 into the tube 6. The cylindrical tubes 5 and 7 are closed at the end by a lid. Below the cover ring there is at least one lateral bore 13, which is surrounded by a liquid-sealing ring 16 before the pressure is exerted (FIG. 4). If the directional pressure is increased so far that the end plate 15 abuts the cylinder end, then the tubes 5 and 7 slide out of their ring holder 16; the holes 13 are released and the liquid 17 can pass in both directions (Fig. 4a).
Werden durch Umstände irgendwelcher Art die Zylinder 1 dekonnektiert, drücken dieIf cylinder 1 is disconnected due to circumstances of any kind, press the
Federn 8 die inneren Zylinderscheiben 10 in den Ausgangszustand, so dass der Flüssigkeitsaustausch 17 unterbrochen wird und der Lamellenverschluss 3 sich schließt. Das Infusionssystem bleibt wegen fehlender Beriihrungsmöglichkeiten steril. Die Figuren 5 und 5a zeigen den berührungslosen inneren Infusionsmechanismus - bevorzugt die Stellun- gen der Federn 8 - im ge- und entspannten Zustand.Springs 8 the inner cylinder disks 10 in the initial state, so that the liquid exchange 17 is interrupted and the lamella closure 3 closes. The infusion system remains sterile due to the lack of contact options. FIGS. 5 and 5a show the contactless inner infusion mechanism - preferably the positions of the springs 8 - in the relaxed and relaxed state.
