KAISERLICHES PATENTAMT. Die Erfindung bezieht sich auf solche Katheter, deren Innenraum durch eine Längszunge in zwei Kanäle zerlegt ist, von denen der eine zur Zuführung einer Spülflüssigkeit in die damit zu behandelnde Körperhöhle, der andere zur Ableitung der Flüssigkeit dient. Bei solchen Kathetern kann es nun vorkommen, daß sich der Ableitungskanal durch Schleim, geronnenes Blut, Epithelzellen ίο u. dgl. verstopft. Um die Entfernung solcher Materien aus dem Ableitungskanal zu ermöglichen, ohne daß der Katheter aus der Körperhöhlung entfernt zu werden braucht, ist nach vorliegender Erfindung der Katheter mit einer Vorrichtung zur Vertauschung der Bestimmung der beiden Flüssigkeitskanäle versehen, so daß die Flüssigkeit dem bisher zur Ableitung benutzten Kanal zugeführt und durch den anderen Kanal abgeleitet werden kann. Hierdurch wird die verstopfende Materie gelockert , in die Körperhöhle zurückgeführt, durch diese Bewegung zerkleinert und zur Ausspülung gebracht. Im Ausführungsbeispiele der Zeichnung ist α das Katheterrohf, b und c sind die Kanäle, die nahe der Spitze in den Öffnungen b1, cl enden. Unten ist dem Katheter ein Stück d mittels Bajonettverschlusses drehbar angeschlossen , welches zwei Stutzen dl, d2 zum 30- Anschlüsse von Schläuchen zur Zu- und Ableitung der Flüssigkeit hat. Das Ende des Katheters ist in das Stück d dicht' eingeschliffen. Benutzt man d1, b als Zuleitung, so nimmt . die Flüssigkeit ihren Rückweg durch c1, c, <i2.; will man. die Richtung des Flüssigkeitslaufes ändern, so dreht man das Stück d, unter Festhalten des Katheters an den Griffen, um so viel, daß der Zuleitungsstutzen dl mit dem Kanal c, die Ableitung d2 mit b in Verbindung kommt, also die Flüssigkeit die Kanäle b, c umgekehrt wie vorher durchströmt. Paten?- Ansprüche:IMPERIAL PATENT OFFICE. The invention relates to such catheters, the interior of which is divided into two channels by a longitudinal tongue, one of which is used to supply a rinsing fluid into the body cavity to be treated therewith, the other to drain the fluid. With such catheters it can happen that the drainage channel becomes blocked by mucus, coagulated blood, epithelial cells and the like. In order to enable the removal of such materials from the drainage channel without the catheter needing to be removed from the body cavity, according to the present invention the catheter is provided with a device for interchanging the determination of the two fluid channels, so that the fluid previously used for drainage Channel fed and can be derived through the other channel. This loosens the clogging matter, returns it to the body cavity, breaks it up and rinses it out. In the exemplary embodiment of the drawing, α is the catheter tube, b and c are the channels which end near the tip in the openings b1, cl. At the bottom of the catheter, a piece d is rotatably connected by means of a bayonet lock, which has two nozzles d1, d2 for connecting tubes for supplying and removing the liquid. The end of the catheter is ground tightly into the piece d. If you use d1, b as a supply line, then take. the liquid makes its way back through c1, c, <i2 .; do you want. change the direction of the flow of fluid, then turn piece d, while holding the catheter by the handles, so much that the inlet connection dl comes into contact with channel c, the discharge line d2 with b, i.e. the liquid comes into connection with channels b, c reversed as before. Sponsors? - Claims: 1. Katheter mit zwei Kanälen zur Zu- -und Ableitung einer Flüssigkeit in ununterbrochenem Strom, dadurch gekennzeichnet, . daß zwischen den Kanälen und deren Anschlußstutzen zur Zu- und Ableitung eine Umschaltvorrichtung angeordnet ist, welche die Änderung der Durchströmrichtung der Flüssigkeit gestattet. 1. Catheter with two channels for the supply and drainage of a liquid in an uninterrupted manner Electricity, characterized. that between the channels and their connecting pieces for supply and discharge a switching device is arranged which allows the direction of flow of the liquid to be changed. 2. Katheter nach Anspruch 1, dadurch gekennzeichnet, daß auf dem hinteren Ende des Katheters eine mit zwei Rohrstutzen (dx,,d'2J versehene, zur Zu- und Ableitung der Flüssigkeit zu den Katheterkanälen dienende Hülse (d) drehbar angeordnet ist, derart, daß jeder ihrer Kanäle (d\, d2) abwechselnd mit dem einen oder dem anderen Katheterkanal (b bzw. c) in Verbindung gebracht werden kann.2. A catheter according to claim 1, characterized in that on the rear end of the catheter a sleeve (d) which is provided with two pipe stubs (d x ,, d ' 2 J and serves to feed and discharge the liquid to the catheter channels) is rotatably arranged , in such a way that each of its channels (d 1, d 2 ) can be brought into connection alternately with one or the other catheter channel (b or c).
