Description

Die Erfindung betrifft ein Verfahren zur Dampfsterilisation von Hohlkörpern mit verhältnismäßig engen Kanälen, insbesondere von Schläuchen, Drains, Bougies, Kathetern, Kanülen u. dgl. Bei der heute üblichen Sterilisation in gespanntem Dampf von I200 C hat es sich herausgestellt, daß das Tnnere derartiger Hohlkörper häufig nicht steril wurde, selbst wenn man die Sterilisationsdauer verlängerte. Diese Erscheinung ist darauf zurückzuführen, daß Luft in den engen Kanälen der Hohlkörper eingeschlossen ist, die bei der Dampfsterilisation nur schwer entweichen kann. Dabei ist zu berücksichtigen, daß aus praktischen Gründen die Hohlkörper (Schläuche u. dgl.) in Schalen eingelegt sind, also in waagerechter Lage sterilisiert werden, während die Dampfströmung dagegen senkrecht von oben nach unten gerichtet ist. The invention relates to a method for steam sterilization of hollow bodies with relatively narrow channels, especially of hoses, drains, bougies, Catheters, cannulas and the like in the case of today's conventional sterilization in compressed steam from I200 C it has been found that the interior of such hollow bodies often did not become sterile even if the sterilization time was increased. This appearance is due to the fact that air is trapped in the narrow channels of the hollow body which can only escape with difficulty during steam sterilization. It must be taken into account that for practical reasons the hollow bodies (hoses and the like) are placed in shells are, so sterilized in a horizontal position, while the steam flow against it is directed vertically from top to bottom.

Nach der Erfindung kann eine sichere Sterilisation, d. h. ein sicheres Austreiben der in den engen Kanälen der Hohlkörper eingeschlossenen Luft dadurch erreicht werden, daß die Hohlkörper vor dem Einbringen in den Sterilisator in Wasser untergetaucht werden, so daß Wasser in die Hohlkörper eindringt. Die engen Kanäle der Hohlkörper füllen sich dabei ganz oder teilweise mit Wasser. Der gespannte Dampf des Sterilisators bringt dieses in den engen Kanälen noch in erheblicher Menge vorhandene Wasser zum Verdampfen, so daß mit diesem sich entwickelnden Dampf die noch in den Kanälen der Hohlkörper eingeschlossenen Luftreste zwangsweise ausgetrieben werden. According to the invention, safe sterilization, e.g. H. a sure one Expulsion of the air trapped in the narrow channels of the hollow body thereby be achieved that the hollow body before being introduced into the sterilizer in water are submerged so that water penetrates into the hollow body. The narrow canals the hollow body is completely or partially filled with water. The tense steam the sterilizer brings this still present in the narrow channels in considerable quantities Water to evaporate, so that with this developing steam the still in the Channels of the hollow body trapped air residues are forcibly expelled.

An Stelle von Wasser kann gegebenenfalls auch eine andere Flüssigkeit verwendet werden, die jedoch nach dem Verdampfen keine Rückstände, wie Salz od. dgl., hinterlassen darf. Aus diesem Grunde ist die Verwendung von destilliertem Wasser für besonders enge Hohlkörper, wie Kanüle u. dgl., vorteilhaft. Instead of water, another liquid can optionally also be used can be used, but after evaporation no residues such as salt or. Like., may leave behind. Because of this, the use of distilled Water is advantageous for particularly narrow hollow bodies such as cannulas and the like.

Eine zur Durchführung des neuen Verfahrens geeignete Tauchschale ist in der Zeichnung beispielsweise dargestellt und im folgenden beschrieben. A dip tray suitable for carrying out the new process is shown for example in the drawing and described below.

Es zeigt Fig. I eine Aufsicht auf eine Tauchsdlale ohne Deckel, Fig. 2 einen Querschnitt durch die mit einem Deckel verschlossene Tauchschale. It shows FIG. I a plan view of a submersible outlet without a cover, FIG. 2 shows a cross section through the immersion bowl closed with a cover.

Es bezeichnet I eine mit Handgriffen 2 versehene Tauchschale, die Durchbrechungen 3 aufweist und mit verschiedenen Fächern 4 zum Einlegen der verschiedenen Hohlkörper versehen ist. Bei dem gezeigten Ausführungsbeispiel bestehen diese Fächer aus einem auf der Schale I befestigten Blech, das wellenförmig gebogen ist. Die Ausbildung dieser Fächer kann jedoch beliebig sein, wobei die Fächer den einzulegenden Hohlkörpern angepaßt sein können. Vorteilhaft sind diese Fächer gemäß Fig. I und 2 nur im mittleren Teil der Schale angeordnet, so daß zwischen diesen Fächern und dem Schalenrand ein Raum verbleibt, in den längere biegsame Hohlkörper, wie Schläuche 5 od. dgl., um die Fächer 4 herum eingelegt werden können. It designates a dip tray provided with handles 2, which Has openings 3 and with different compartments 4 for inserting the various Hollow body is provided. In the embodiment shown, these compartments exist from a sheet metal attached to the shell I, which is bent in a wave-like manner. the However, these subjects can be designed in any way, with the subjects being the ones to be inserted Hollow bodies can be adapted. These compartments are advantageous according to FIGS 2 arranged only in the middle part of the shell, so that between these compartments and A space remains around the edge of the shell into which longer, flexible hollow bodies, such as hoses, can be accommodated 5 or the like, around which compartments 4 can be inserted.

Um beim Untertauchen der Schale I in Wasser den Auftrieb der eingelegten Hohlkörper zu verhindern, ist ein Deckel 6 vorgesehen, der nach dem Einlegen der Hohlkörper fest mit der Schale I verbunden werden kann. Dieser Deckel ist ebenfalls mit Durchbrechungen 7 versehen, um ein Hindurchströmen von Luft und Wasser beim Untertauchen zu ermöglichen. Damit die eingelegten Hohlkörper beim Untertauchen innerhalb der Schale nicht durcheinander kommen, sind die Fächer 4 so hoch ausgebildet. daß deren Trennwände 8 bis dicht an den Deckel 6 heranreichen. In order to increase the buoyancy of the inlaid when submerging the shell I in water To prevent hollow body, a cover 6 is provided, which after inserting the Hollow body can be firmly connected to the shell I. This lid is also provided with openings 7 to allow air and water to flow through Allow immersion. So that the inserted hollow bodies when submerged do not get mixed up inside the shell, the compartments 4 are designed so high. that their partitions 8 come close to the cover 6.
