Description
Kanülen für :medizinische Zwecke, z. B. Spritzen, werden in Dampf von i 2o' C sterilisiert. Zu diesem Zweck werden sie .in eine Schale oder einen kleinen Behälter eingelegt, der seinerseits in den Autoklaven eingesetzt wird. Diese Art der Sterilisation ist unvollkommen, da aus den liegenden Kanülen die in diesen eingeschlossene Luft schlecht entweichen kann. Es :besteht also die Gefahr, daß in den einzelnen Kanülen Luftreste während der Sterilisation verbleiben, die eine vollständige Sterilisation im Innern der Kanüle verhindern.Cannulas for: medical purposes, e.g. B. syringes, are in steam Sterilized by i 2o 'C. For this purpose they are placed in a bowl or a inserted in a small container, which in turn is inserted into the autoclave. These The type of sterilization is imperfect, because the cannulas in them are from the lying cannulas trapped air can hardly escape. It: there is therefore the danger that Air residues remain in the individual cannulas during sterilization Prevent complete sterilization inside the cannula.
Nach der Erfindung wird dieser Mangel dadurch beseitigt, daß die Kanülen mit zweckmäßig destilliertem Wasser @durchgespült und ,diese -mit Wasser gefüllten Kanülen @dann mit Dampf sterilisiert werden. Mit diesem vorherigen Durchspülen der Kanüle wird nicht nur eine Reinigung derselben, sondern vor allem eine Füllung ganz-oder teilweise mit Wasser bewirkt. Bei der nachfolgenden Sterilisation wird das in den Kanülen befindliche Wasser verdampft -und mit diesem Dampf die in den Kanülen eingeschlossene Luft ausgetrieben. Vorteilhaft werden die Kanülen in hängender, senkrechter Lage sterilisiert, @da bei dieser senkrechten Lage die Luft infolge ihrer größeren Schwere gegenüber Dampf mach unten austreten kann, wobei dieses Herausfallen der Luft durch den nachschiebenden Dampf ,unterstützt wird.According to the invention, this deficiency is eliminated in that the cannulas rinsed with appropriately distilled water @ and filled with water Cannulas @ can then be sterilized with steam. With this previous flushing through of the The cannula is not only used for cleaning the same, but above all a filling or filling partially effected with water. During the subsequent sterilization, this is stored in the The water contained in the cannulas evaporates - and with this vapor the water enclosed in the cannulas Air expelled. The cannulas are advantageous in a hanging, vertical position sterilized, @ because in this vertical position the air due to its greater weight opposite to steam can escape below, whereby this falling out of the air through the following steam, is supported.
Zur Durchführung des neuen Verfahrens wird eine Vorrichtung ;benutzt, die in der Zeichnung beispielsweise dargestellt ist.To carry out the new method, a device is used; which is shown in the drawing, for example.
Diese,besteht aus einem Ständer i mit einer Einsteckplatte 2 für die Kanülen 3. Die Platte 2 .ist mit Bohrungen 4 versehen, die kleiner sind als der Kanülenkopf 5, so daß die Kanülen gewissermaßen in dem Ständer aufgehängt sind. Diese hängende Anordnung der Kanülen ermöglicht nicht nur in Verbindung mit dem vorherigen Spülen mit destilliertem Wasser eine sichere Sterilisation, sondern .gestattet das unmittelbare Aufstecken auf den Spritzenkopf, der lediglich .auf den Kanülenkopf 5, der im Ständer i 'hängenden Kanüle aurfgedrückt wird. Die sterile Kanüle wird also auf diese Weise schnell und bequem .auf der Spitze :befestigt, ohne daß ;hierbei eine Reinfektion durch Handberührung cd. dgl. eintreten kann.This consists of a stand i with an insert plate 2 for the Cannulas 3. The plate 2. Is provided with holes 4 which are smaller than the Cannula head 5, so that the cannulas are, as it were, suspended in the stand. This hanging arrangement of the cannulas allows not only in connection with the prior rinsing with distilled water is a safe sterilization, but allowed the direct attachment to the syringe head, which is only .on the cannula head 5, which is pressed out in the stand i 'hanging cannula. The sterile cannula will in this way quickly and conveniently. on the tip: attached without; here reinfection by touching the hand cd. Like. Can occur.
Der vorbeschriebene Ständer i kann vorteilhaft, wie in -der Zeichnung dargestellt ist, als kleiner Sterilisierbehälter ausgebildet sein, der mit gelochten mit Filter 6 abgedeckten Boden- und Deckelteilen 7 und 8 versehen ist. Dieser Sterilnsierbehälte.r dientsowohl zur Sterilisation .der Kanüle als auch zur sterilen Aufbewahrung derselben.The stand i described above can be advantageous, as in the drawing is shown, be designed as a small sterilization container with perforated with a filter 6 covered base and cover parts 7 and 8 is provided. This Sterilnsierbehält.r serve both for sterilization of the cannula and for sterile storage of the same.
