Description
Vorrichtung zur Entfernung eitriger Sekrete aus der Harnröhre.. In der Praxis hat es sich herausgestellt, daß die Vorrichtung gemäß Patent 3302,84 aus technischen Gründen nicht so genau hergestellt werden kann, daß die innere Röhre sich eng und luftdicht an die äußere Röhre anschmiegt. Es ist sowohl zwischen der inneren und äußeren Röhre wie auch zwischen den Rohrenden ein Raum vorhanden.. Werden nun die beiden ineinandergeschobenen Röhren aus der Harnröhre herausgezogen, bei Luftverdünnung innerhalb des Gesamtinstrumentes, so wird dieser Raum durch das oberste, aus der Harnröhre herausgezogene Fenster mit der atmosphärischen Luft in Verbindung gesetzt. Dadurch wird der luftverdünnte Raum in beiden Röhren mit Luft angefüllt, und eine Saugkraft auf die Harnröhrenschleimhaut kann an keinem Punkte des Instrumentes weiterhin ausgeübt werden.Device for removing purulent secretions from the urethra. In practice it has been found that the device according to Patent 3302.84 cannot be manufactured so precisely for technical reasons that the inner tube fits tightly and airtight to the outer tube. There is a space between the inner and outer tube as well as between the tube ends. If the two nested tubes are now pulled out of the urethra, with air dilution within the entire instrument, this space is made up by the uppermost window pulled out of the urethra the atmospheric air. As a result, the air-diluted space in both tubes is filled with air, and a suction force on the urethral mucous membrane cannot continue to be exerted at any point on the instrument.
Diesen Übelstand soll durch vorliegende Erfindung abgeholfen werden.This drawback is intended to be remedied by the present invention.
Die Vorrichtung ist im wesentlichen die gleiche wie bei dem Hauptpatent 330284. Die beiden Röhren sind jedoch an den Einführungsenden so gestaltet, daß die innere Röhre durch die äußere um 2 bis .4 mm durchschiebbar ist, und zwar so, daß die durch das Hauptpatent bereits geschützten besonderen Schutzvorrichtungen nicht in Fortfall kommen.The device is essentially the same as in the main patent 330284. However, the two tubes are designed at the insertion ends so that the inner tube can be pushed through the outer by 2-4 mm, in such a way that the main patent already Protected special protective devices do not disappear.
In der beiliegenden Zeichnung ist die neue Vorrichtung in beispielsweiser Ausführungsform dargestellt. Die Bezeichnung der einzelnen Teile ist in Übereinstimmung mit dem Hauptpatent 33o2$4 erfolgt.In the accompanying drawing, the new device is shown by way of example Embodiment shown. The designation of the individual parts is consistent with the main patent 33o2 $ 4.
