Abstract

An urethral indwelling catheter designed in such a way that the urine emerges freely into the urethra in the central region of the catheter and rinses the urethra. The flow of urine along the urethral wall towards the opening of the urethra thereby prevents an ascending infection. Before the urine leaves the urethra it is passed back into the catheter. At the catheter end there is a connection to one of the commercially available urine collection systems.

Description

Katheter catheter

Die Erfindung betrifft einen Harnröhrendauerkatheter für den Mann mit den im Anspruch 1 enthaltenen Merkmalen. Durch das Kennzeichnungsmerkmal des Anspruches 2 ist eine besonders intensive Bespölung der Harnröhre, sowie eine Produktionsvereindachunc gegenüber dem Patent DE-Patentanmeldung P 32.02713.3-35 möglich. Die beiden Innenführungsteile werden hier entweder nur vom Auffüllkanal (7) oder zusätzlich einem oder mehreren Verbindungssträngen (33) miteinander verbunden, so daß der Urin frei die Harnröhrenwand (4) bespülen kann, bevor er in den der Harnröhrenmündung nahegelegenen Innenführungsteil (16) wieder eintritt, welches den Urin zu eine: der üblichen Urinsammelsysteme weiterführt.The invention relates to an indwelling urethral catheter for men with the features contained in claim 1. The identification feature of the Claim 2 is a particularly intensive flushing of the urethra, as well as a production club roof compared to the patent DE patent application P 32.02713.3-35 possible. The two inner guide parts are here either only from the filling channel (7) or one or more in addition Connecting strands (33) connected together so that the urine clears the urethral wall (4) before it can be flushed into the inner guide part close to the urethral orifice (16) re-enters, which leads the urine to one of the usual urine collection systems.

Um das Einführen des in seinem mittleren Abschnitt (15) instabilen Katheters zu ermöglichen, wird eine l:etall- oder Kunststoffsonde nach Anspruch 3 in das Lumen der beiden Innenführungsteile (14, 16) eingeführt und anschließend. nach richtiger Plazierung des Katheters in der Harnröhre und Blase und nach Auffüllen des Ballons wieder entfernt.To the introduction of the unstable in its middle section (15) To enable catheters, a metal or plastic probe according to claim 3 inserted into the lumen of the two inner guide parts (14, 16) and then. after correct placement of the catheter in the urethra and bladder and after filling of the balloon removed again.

Um ein Ausfließen von Urin neben den. außeren Innenführungsteil (16) und der Harnröhrenwand (4) zu verhindern, kann der InnenführunBsteil nn enf ührun s teil nach Anspruch perforiert sein oder er weist zur Abdichtung eine aufblasbare Ballonmenschette oder einen Schaumstoffring nach Anspruch 5 auf.To avoid leakage of urine in addition to the. outer inner guide part (16) and to prevent the urethral wall (4), the inner guide part can lead into it s part according to claim be perforated or it has an inflatable seal for sealing Balloon cuff or a foam ring according to claim 5.

Bei der im Kennzeichnur @@@ ck@@l des Anspruches 6 wiedergegebenen Variante wird auf die bekannte oligodynamische Wirdung bestimmter Metalle zurückgegriffen, sowie diese Wirdung durch die allgemein bekannte Wanderung von Bakterien irr elektrischen Feld verstärkt.In the case of the @@@ ck @@ l in the identifier of claim 6 reproduced Variation is based on the well-known oligodynamic production of certain metals, as well as this being caused by the well-known migration of bacteria in an electric way Reinforced field.

Der innere Innenführungsteil (14) besitzt zentral ein großes, den Urin führendes Lu@en (10), welches sich bei liegendem Katheter in die bulbäre Harnröhre (4) öffnet. Auch der äußere Innenführungsteil besitzt ein großes zentrales Lumen (13) zur Urinableitung, welches zum erweitertan Katheterende (37) zieht, hier erfolgt der Anschluß an ein Urinsammelsystem.The urine inlet opening is located near the catheter tip (5) (9). The inner inner guide part (14) has a large central part that carries the urine Lu @ en (10), which opens into the bulbar urethra (4) when the catheter is in place. The outer inner guide part also has a large central lumen (13) for urine drainage, which pulls to the extended catheter end (37), here the connection to a Urine collection system.

Der äußere Innenführungsteil (16) kann die Perforationsöffnungen (38) besitzen und mit der Ballonmanschette (31) versehen sein, deren Auffüllkanal zum Kontrollballon (32) führt.The outer inner guide part (16) can contain the perforation openings (38) own and be provided with the balloon cuff (31), the filling channel for Control balloon (32) leads.
