Description
Vorrichtung zur Entfernung eitriger Sekrete aus der Harnröhre. Mit der Vorrichtung nach dem Hauptpatent 330284 kann aus anatomischen Gründen die etwa 2 bis 3 cm lange, hintere Harnröhre nicht abgesaugt werden. Es ist nötig, daß ein Instrument, mit dem man in die hintere Harnröhre gelangen will, am Einführungsende eine Krümmung in Hakenform besitzt. Diese Form schließt aber aus, daß die Innenröhre durch die ganze Außenröhre hindurch und darüber hinaus geschoben werden kann. Das Problem, gleichwohl sämtliche Sekrete in @ der innerenRöhre zusammenzuziehen und eine Saugwirkung auf die Schleimhaut beim Herausziehen des Gesamtinstrumentes bis zur Harnröhrenmündung durch die Öffnung am Einführungsende auszuüben, wird beim vorliegenden Gegenstand trotzdem gelöst, und zwar dadurch, däß durch das Einschalten eines Gummiringes ein dichter Anschluß des Innenrohres an das Hakenrohr k erzielt wird.Device for removing purulent secretions from the urethra. With the device according to the main patent 330284 , the approximately 2 to 3 cm long, posterior urethra cannot be suctioned off for anatomical reasons. It is necessary that an instrument with which one intends to enter the posterior urethra has a curvature in the shape of a hook at the insertion end. However, this shape precludes the inner tube from being able to be pushed through and beyond the entire outer tube. The problem of nevertheless contracting all the secretions in the inner tube and exerting a suction effect on the mucous membrane when pulling out the entire instrument to the urethral opening through the opening at the insertion end is nevertheless solved with the present subject, namely by the fact that a more tight seal is created by switching on a rubber ring Connection of the inner tube to the hook tube k is achieved.
Auf der Zeichnung bedeutet Fig. i eine Seitenansicht des Instrumentes, Fig. 2 einen senkrechten Längsschnitt durch den unteren Teil mit seinem Hakenende.In the drawing, Fig. I means a side view of the instrument, Fig. 2 is a vertical longitudinal section through the lower part with its hook end.
Die Röhre a, die nur drei etwa i cm lange Fenster l aufweist, ist mit einem aufschraubbaren Haken k versehen; dieser läuft halbkugelförn-ig am Einführungsende aus und hat daselbst eine Öffnung, deren Kante rund geschliffen ist, damit beim Einführen dieser Röhre keine Verletzung der Harnröhrenschleimhaut stattfinden kann. In die Röhre a wird eine gerade ungefensterte Röhre a eingeschoben, die bis hinter die Fenster l vorstößt. Sie ist ebenfalls am Einführungsende halbkugelförmig verjüngt. Das innere Schraubengewinde befindet sich innerhalb des Hakenrandes, das äußere an der äußeren Wand des Rohres a. Hinter dem Schraubengewinde im hohlen Hakenrand befindet sich ein senkrecht zum Rohr befindlicher, etwa 2 mm breiter, konzentrisch eingelegter Ringvorsprung n.. Auf diesen Ring m ist ein Gummiring o lose auflegbar. Ist nun das Instrument zusammengeschraubt, so stößt die innere Röhre e beim Vorschieben in die Röhre a und in den hakenförmigen Ansatz k mit ihrer unteren Kante auf den Gummiring. Wird die Röhre e fest gegen den Gummiring gedrückt, so besteht ein luftdicht abgeschlossener Raum von der Hakenendöffnung an bis zum Ende der Röhre e, wo, der Sauggummiball angesetzt wird. Der Raum zwischen den Röhren a und e kann nunmehr unbedenklich mit der atmosphärischen Luft in Verbindung gebracht werden, ohne daß die Saugkraft am hakenförmigen offenen Ende davon betroffen wird. Der Zutritt der atmosphärischenLuft zwischen denRöhren a und e, der nach dem Saugakt erwünscht ist, damit das Instrument ohne Verletzung der an den saugenden Fenstern befindlichen Schleimhaut herausgenommen werden kann, kann erfolgen durch ein Lochfenster p -am -oberen Ende der äußeren Röhre a, das sich außerhalb der Harnröhre befindet. Es wird durch eine Gurnmi-Stulpe y von etwa z cm Länge geschlossen. Sobald nun dieser Gummischlauch vom Loch abgehoben wird, ist das Fenster geöffnet und es kann atmosphärische Luft zwischen d:e Röhren a und e eintreten. Es saugt beim Herausnehmen trotz dieser Lüftung des Fensters die Öffnung am Hakenende infolge obengeschilderter Konstruktion weiter, ein Saugakt, der erwünscht ist und keine Schwierigkeiten beim Herausnehmen des Gesamtinstrumentes aus der Harnröhre bereitet.The tube a, which has only three windows l about 1 cm long, is provided with a screw-on hook k; This ends in a hemispherical shape at the insertion end and has an opening there, the edge of which is rounded so that the urethral mucosa cannot be injured when this tube is inserted. A straight unwindowed tube a is pushed into the tube a, which extends beyond the window l. It is also tapered hemispherically at the insertion end. The inner screw thread is located inside the hook edge, the outer one on the outer wall of the tube a. Behind the screw thread in the hollow hook edge there is an approximately 2 mm wide, concentrically inserted annular projection n perpendicular to the pipe. A rubber ring o can be loosely placed on this ring m. If the instrument is now screwed together, the lower edge of the inner tube e hits the rubber ring with its lower edge when it is pushed forward into the tube a and into the hook-shaped projection k. If the tube e is pressed firmly against the rubber ring, there is an airtight space from the hook end opening to the end of the tube e, where the suction rubber ball is attached. The space between the tubes a and e can now safely be brought into contact with the atmospheric air without the suction force at the hook-shaped open end being affected. The access of the atmospheric air between the tubes a and e, which is desired after the suction act, so that the instrument can be removed without damaging the mucous membrane located on the suction windows, can take place through a perforated window p - at the upper end of the outer tube a, the is outside the urethra. It is closed by a Gurnmi cuff y about z cm long. As soon as this rubber hose is lifted from the hole, the window is open and atmospheric air can enter between d: e tubes a and e. When it is removed, despite this ventilation of the window, it continues to suck the opening at the end of the hook as a result of the construction described above, a suction act that is desirable and does not cause any difficulties in removing the entire instrument from the urethra.
