Description

Die Anregung zu dem erfindungsgemäßen Katheter veranlaßt die Tatsache, daß ein Dauerkatheter zur Ermöglichung des Abflusses von Flüssigkeiten durch sein mögliches Heraus gleiten aus indem Einführungskanal oft nur durch umiständ liche äußere Fixationen zu erreichen ist. The stimulation of the catheter according to the invention causes the fact that be an indwelling catheter to allow the drainage of fluids through possible slip out of the insertion channel often only through circumstantial external fixations can be achieved.

Diese Nachteile kommen bei vorliegender Konstruktion in Wegfall. These disadvantages do not apply to the present design.

Der neue Dauerkatheter besteht aus elastisch, Material und weist im Ruhezustand (im ungelstreckten Zustand) eine elastische Kragenbildung auf, kurz hinter der Ausflußöffnung (Fig. 1 d) des Abfluß rohres (Fig. I c). The new indwelling catheter consists of elastic, material and points in the resting state (in the unstretched state) an elastic collar formation, in short behind the outlet opening (Fig. 1 d) of the drain pipe (Fig. I c).

Die Streckung erfolgt vor der Ingebrauchnahme durch Einführung eines in seiner Längsachse starren, jedoch. seitlich elastischen Stabes (Fig. 2), wobei die Länge des Stabes so abgemessen ist, daß nach völliger Einführung das gekröpfte Ende des Stabes (Fig. 2 e) in den Ringwulst vor Ausgang des Katheters (Fig. Ib) sich einfügt und IdEabei eine Fixierung erhält. The stretching takes place before use by introducing a rigid in its longitudinal axis, however. laterally elastic rod (Fig. 2), wherein the length of the rod is measured in such a way that after complete introduction the cranked End of the rod (Fig. 2 e) in the annular bead in front of the exit of the catheter (Fig. Ib) fits in and IdE thereby receives a fixation.

Dadurch wurde gleichzeitig der Katheter in seiner Längsachse so weit gedehnt, daß die Kragenbil, d : verstrichen ist und nunmehr die Einführung zur Ingebrauchnahme durch die betreffende Öffnung möglich ist (Fig. 3). As a result, the catheter became so wide in its longitudinal axis at the same time stretched so that the collar image, d: has passed and now the introduction for use is possible through the relevant opening (Fig. 3).

Nach erfolgter Einführung wird unter Beibehaltung der augerblicklich erforderlichen Lage der Dehnungsstab aus dem Katheter gezogen, wodurch durch seine eigene Elastizität die Kragenbildung wieder hergestellt ist. Ein Herausgleiten, sei es durch aktive, sei es durch passive Einflüsse, ist so verhindert. Once it has been introduced, the instantaneous required location of the expansion rod pulled out of the catheter, thereby through its own elasticity the collar formation is restored. Slipping out be it through active, be it through passive influences, is prevented.

Mit dieser Konstruktion wird erreicht: 1. eine einfache natürliche Fixierung am Abflußort zur Entleerung beliebiger flssigkeitsgefüllter Hohlräume; 2. bei Anwendung auf medizinischem Gebiet wird jede kompliziierte Fixierung des Katheters durch lästige Verbände hinfällig; 3. die Kragenbildung verursacht durch Idie biologisch-mechlanische Einwirkung (Blasendruck) eine vorteilhafte Prostatamassage sowie Dehnung der infolge krankhafter Veränderung verengten Harnröhre im Abschnitt der Prostata; 4. die Anwendbarkeit erstreckt sich auf alle Kathetergrößen. With this construction is achieved: 1. A simple natural Fixation at the drainage point for emptying any liquid-filled cavities; 2. When used in the medical field, any complicated fixation of the Catheter obsolete due to annoying bandages; 3. the collar formation caused by The biological-mechanical action (bladder pressure) is a beneficial prostate massage and stretching of the urethra narrowed as a result of pathological changes in the section the prostate; 4. Applicability extends to all catheter sizes.
