Description
Katheter. Bei der Einführung von Kathetern in die Harnröhre besteht die Gefahr, daß an den Wänden sitzende Bakterien, Gonokokken o. dgl., durch das einzuführende Katheter in das Innere der Harnröhre geschoben werden. Um dieses zu vermeiden, hat man schon vorgeschlagen, das einzuführende steife Rohr mit einem biegsamen Mantel zu umgeben, welcher bei weiterem Einschieben des Rohres in die Körperhö4le aus diesem herausgezogen wird und sich zwischen die Innenwände der KörperhöhIung und die Außenflächen des Rohres legt. Dabei ist es aber nicht ausge-.schlossen, daß der Mantel zerreißt, oder daß das Sekret, das die Infektionserreger enthält, durch den Mantel hindurchdringt. Auch ist einZurückströmen der benutztenSpülflüssigkeit bei der erwähnten bekannten Vorrichtung nicht möglich. Gemäß der vorliegenden Erfindung wird nun dieser biegsame Mantel dadurch überflüssig gemacht, daß das Katheter teleskopartig ausgebildet wird.Catheter. When inserting catheters into the urethra it consists the risk of bacteria, gonococci or the like sitting on the walls, through the catheter to be inserted can be pushed into the interior of the urethra. To this too avoid, it has already been proposed to insert the rigid tube with a to surround flexible jacket, which with further insertion of the tube into the Body cavity is pulled out of this and is located between the inner walls of the body cavity and lays the outer surfaces of the pipe. But it is not ruled out that the coat tears, or that the secretion containing the infectious agents, penetrates through the jacket. There is also a backflow of the used washing liquid not possible with the known device mentioned. According to the present invention this flexible jacket is now made superfluous in that the catheter is telescopic is trained.
Auf der Zeichnung stellt Abb. i den Prfindungsgegenstand in Ansicht dar. Die Abb. -- bis 4 zeigen Einzelteile desselben, Abb. 5 eine Hilfsvorrichtung.In the drawing, Fig. I shows the subject of the test in a view. Figs. - to 4 show individual parts of the same, Fig. 5 shows an auxiliary device.
Der Teil A des teleskopartigen Katheters bleibt an der Einführungsstelle stehen und gelangt nicht bis zu dem auszuspülenden Krankheitsherd. Der Teil B wird durch den Teil A hindurchgeführt, und durch diesen wird nun der Teil C geführt, der die Spülflüssigkeit zuführt. Abb. 5 stellt einen massiven Stift dar, der etwas länger als der Teil A ist, und der in den Teil A festgesteckt wird, um die Einführung des letzteren ohne Beschwerden für den Patienten zu ermöglichen. Die zugeführte Flüssigkeit kann seitlich an den Teilen B und A vorbei zurückströmen.Part A of the telescopic catheter remains at the insertion point and does not reach the focus of the disease to be flushed out. Part B is passed through part A , and part C , which supplies the rinsing liquid, is now passed through this. Fig. 5 shows a solid pin which is slightly longer than part A and which is pinned into part A to enable the latter to be inserted without discomfort for the patient. The supplied liquid can flow back past parts B and A laterally.
