Aufgabe:Task:

Der Erfindung liegt die Aufgabe zugrunde, die Gefahr einer Kontamination mit Mikroorganismen an den Verbindungsöffnungen des Infusionssystems zu v/erringernThe invention is based on the task of reducing the risk of contamination with microorganisms at the connection openings of the infusion system

durch die Möglichkeit einer optischen, statt einer manuellen Verschlußkontrolle,through the possibility of an optical, instead of a manual shutter control,

sowie durch eine langgestreckte Form der Verbin= dungsvorrichtung den Abstand der Hände zur Infu= sionsöffnung möglichst groß zu halten,and to keep the distance between the hands and the infusion opening as large as possible by using an elongated shape of the connecting device,

swie durch eine relativ schwach konturierte Ober= fläche der Verbindungsvorrichtung, sowie durch einen Klickeffekt, der ungewolltes Öffnen zu erschweren vermag.as well as by a relatively weakly contoured surface of the connecting device, as well as by a click effect that can make accidental opening more difficult.

Lösung:Solution:

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Verbindungsvorrichtung aus zwei Formstücken besteht, die aus steif-elastischem, bruchfestem und chemische beständigem Kunststoff gefertigt sind, die eine jeweils gleiche Zahl hakenartiger"-Form= stücke mit jeweils paarweiser formschlüssiger In= einanderpassung besitzen mit jeweils angrenzenden nutenförmigen Vertiefungen.This object is achieved according to the invention in that the connecting device consists of two molded pieces made of rigid-elastic, break-proof and chemically resistant plastic, each of which has an equal number of "hook-like" molded pieces, each of which fits together in pairs with adjacent groove-shaped recesses.

Beide Verbindungsstücke (1,2) bestehen aus einem homogenen, steif-elastischen, bruchfesten und ehe= misch beständigen Kunststoff, mit dem die beiden eingefügten Enden der Infusionsschläuche eine chemisch und mechanisch beständige Verbindung einge= hen müssen.Both connecting pieces (1,2) consist of a homogeneous, stiff-elastic, break-proof and chemically resistant plastic, with which the two inserted ends of the infusion tubes must form a chemically and mechanically resistant connection.

Die äußere Begrenzungsfläche der Freiraumnute (13) muß von der Fixierungshaken-Endfläche (14) des Gegenstücks in geschlossenem Zustand einen definierten Abstand haben, der sich ergibt aus der Ausueichbeuegung dieses Hakens (4) beim Schließ= Vorgang. Desgleichen ist bei der Fixierungshaken-Endfläche (15) ein definierter Abstand einzuhalten.The outer boundary surface of the clearance groove (13) must have a defined distance from the fixing hook end surface (14) of the counterpart in the closed state, which results from the balancing bending of this hook (4) during the closing process. Likewise, a defined distance must be maintained for the fixing hook end surface (15).

Die Grundfläche der Freiraumnuten (5,6) stellt ei= ne kurze Zylindermantelfläche dar.The base area of the clearance grooves (5,6) represents a short cylinder surface.

Zur Gebrauchsmusteranmeldung von Eberhard Noebel vom 08. 10. 1998 Fortsetzung: Beschreibung (Blatt 4)Regarding the utility model application by Eberhard Noebel dated October 8, 1998 Continuation: Description (Page 4)

Die Freiraumnuten (5,6) müssen eine ausreichende Umfangslänge vertikal zur Körperachse besitzen, um beim Schließ- oder Öffnungsvorgang die erforder= liehe Schrägstellung der Verbindungsstücke im zusammengeschobenen Zustand zu ermöglichen.The clearance grooves (5,6) must have a sufficient circumferential length vertical to the body axis in order to enable the required inclination of the connecting pieces in the pushed-together state during the closing or opening process.

Es entsteht ein Klickeffekt. Zur Erlangung exakt dieses Widerstandes ist Querschnittsfläche der Fixierungshakenunter Berücksichtigung der Elasti= zitätskonstanten des Materials darauf abzustellen.A click effect occurs. To achieve exactly this resistance, the cross-sectional area of the fixing hooks must be adjusted taking into account the elastic constant of the material.
