Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Die Handhabung der bisher üblichen Kathetersterilisatoren, welche mit Dampf arbeiteten, war ä'ufserst unbequem, so dafs die Sterilisation der Katheter viel Zeit in Anspruch nahm. Die Verbindung der im Innenraum B befindlichen Katheter mit ' dem eigentlichen Dampfentwickler A geschah seither durch Gummischlä'uche, wobei viel Condenswasser entstand und die Katheter litten.The handling of the previously common catheter sterilizers, which worked with steam, was extremely inconvenient, so that the sterilization of the catheters took a long time. The connection of the catheters located in the interior B with the actual steam generator A has since been made by rubber hoses, which resulted in a lot of condensation water and the catheters suffered.

Diese Mängel lassen sich durch Anordnung einer Dampfkammer mit hohlem Dichtungsstöpsel beseitigen. These deficiencies can be eliminated by arranging a steam chamber with a hollow sealing plug.

Der derart verbesserte Apparat besteht aus einem Wasserreservoir E mit seitlichem Einfülltubus und cylindrischem Rohr A, mit welchem ein im Innern des letzteren liegendes, unten geschlossenes Rohr B verbunden ist. Im oberen Theil des Raumes A befindet sich die Kammer K, welche, so lange der Apparat nicht benutzt wird, einerseits oben mit der Atmosphäre und andererseits unten mit dem Rohr B in Verbindung steht. Die Kammer K wird während der Benutzung des Apparates durch einen hohlen Stöpsel, welcher zwei Gummistopfen trägt, gegen die äufsere Atmosphäre, sowie gegen das Innere des Rohres B abgesperrt.' The apparatus improved in this way consists of a water reservoir E with a lateral filling tube and a cylindrical tube A, to which a tube B , located inside the latter and closed at the bottom, is connected. In the upper part of room A there is chamber K, which, as long as the apparatus is not in use, communicates with the atmosphere at the top and with tube B at the bottom. The chamber K is blocked from the outside atmosphere and from the inside of the tube B by a hollow stopper which carries two rubber stoppers while the apparatus is in use.

Die Wirkungsweise des Apparates nun ist folgende:The mode of operation of the apparatus is as follows:

Der röhrenförmige Körper, z. B. Katheter F, wird an das düsenförmige Ende des Stöpsels G gesteckt und, sobald die Dampfbildung vor sich geht, in das Innere des Rohres B gehängt. Da die beiden Gummistopfen des Hohlstöpsels G die Kammer nach beiden Seiten abdichten, so werden die Dämpfe gezwungen, durch das Röhrchen Jf? in die doppelwandige Kammer K zu treten. Von hier aus können sie nur durch die Löcher I des Stöpsels G in das Innere des Katheters treten, durchströmen denselben in der Pfeilrichtung von oben nach unten, umspülen ihn auch aufsen und treten durch das Abzugsrohr D ins Freie.The tubular body, e.g. B. Catheter F, is plugged into the nozzle-shaped end of the plug G and, as soon as the vapor formation takes place, hung in the interior of the tube B. Since the two rubber stoppers of the hollow plug G seal the chamber on both sides, the vapors are forced to pass through the tube Jf? to step into the double-walled chamber K. From here they can only enter the interior of the catheter through the holes I of the plug G , flow through it in the direction of the arrow from top to bottom, wash around it and pass through the vent pipe D into the open.
