Abstract

In parent patent, catheter is provided adjacent its insertion end with an axially displaceable sleeve which is attached to the insertion end with one of its ends whilst the other end is slidable in a direction which tensions the sleeve to reduce the dia. of a bead formed intermediate the length of the sleeve. The bead in its distended position forms a seal for the inserted end of the catheter. In this addn., the bead is formed by a peripheral array of strips which in the relaxed state are deformed accurately and constitute part of the sleeve. The bead is formed by a ring made of highly resilient foamed plastics materials.

Description

Katheter mit einer Abdichtvorrichtung Catheter with a sealing device

Zusatz zu Patent .... (Patentanmeldung P 26 53 424.7) Das Patent ..... (Patentanmeldung P 26 53 424.7) betrifft einen Katheter mit einer Abdichtvorrichtung in Form eines ihn umgebenden axial frei beweglichen Schlauches aus elastischem Material, der im Bereich des Einführendes des Katheters an diesem befestigt ist, wobei der Schlauch mit wenigstens einer den Katheter umgebenden Ausbauchung versehen ist, deren Durchmesser durch Verschiebung des freien Schlauchendes im Sinne einer Streckung des Schlauches verringerbar ist.Addition to patent .... (patent application P 26 53 424.7) That Patent ..... (patent application P 26 53 424.7) relates to a catheter with a sealing device in the form of an axially freely movable hose made of elastic material surrounding it, which is attached to the catheter in the region of the insertion end, the The tube is provided with at least one bulge surrounding the catheter, their diameter by shifting the free end of the hose in the sense of stretching of the hose can be reduced.

Die Erfindung ist eine Weiterbildung des Gegenstandes des Hauptpatents. Sie besteht darin, daß die Ausbauchung durch in den Schlauch eingearbeitete, in entspanntem Zustand gekrümmte Lamellen gebildet ist. Die Ausbauchung des Schlauches kann auch durch einen in den Schlauch eingesetzten, den Katheter umgebenden Ring aus geschäumtem Material, wie einem hochelastischen Schaumstoff, gebildet sein. Hierdurch wird die Herstellung der Ausbauchung in dem den Katheter umgebenden Schlauch mit einfachsten Mitteln ermöglicht, wodurch auch eine sehr sichere Abdichtung gewährleistet ist.The invention is a further development of the subject matter of the main patent. It consists in the fact that the bulge is formed by in relaxed state curved lamellae is formed. The bulge of the hose can also be achieved by means of a ring that is inserted into the tube and surrounding the catheter be made of foamed material, such as a highly elastic foam. This results in the production of the bulge in the tube surrounding the catheter made possible with the simplest of means, which also ensures a very secure seal is.

Die Lamellen können durch axiale Längsschlitze des Schlauches gebildet sein. Um die Abdichtung zu verbessern, können die Lamellen von einer hochelastischen Folie umgeben sein. Es ist auch möglich, den Ring aus geschäumtem Material so auszubilden, daß das geschäumte Material die Ausnehmungen zwischen den Lamellen ausfüllt. Bei Verwendung eines luftundurchlässigen geschäumten Materials, wird auf diese Weise ebenfalls eine sichere Abdichtung gewährleistet.The lamellae can be formed by axial longitudinal slots in the hose be. In order to improve the sealing, the slats can be made of a highly elastic Be surrounded by foil. It is also possible to design the ring from foamed material in such a way that that the foamed material fills the recesses between the slats. at Using an air-impermeable foamed material is made in this way also a secure seal guaranteed.

Die Erfindung ist im folgenden anhand der Zeichnung näher erläutert. In der Zeichnung zeigt: Fig. 1: eine Seitenansicht eines erfindungsgemäßen Katheters, bei welchem die Ausbauchung des Schlauches durch Lamellen gebildet ist, teilweise im Schnitt, und Fig. 2: eine Seitenansicht eines erfindungsgemäßen Katheters, bei welchem die Ausbauchung des Schlauches durch einen eingesetzten Ring aus geschäumtem Material hergestellt ist.The invention is explained in more detail below with reference to the drawing. The drawing shows: FIG. 1: a side view of a catheter according to the invention, in which the bulge of the hose is formed by fins, partially in section, and FIG. 2: a side view of a catheter according to the invention, at which the bulge of the hose by an inserted ring made of foamed Material is made.

In Fig. 1 ist mit 1 der Führungskatheter bezeichnet, der an seinem vorderen Teil bei 2a mit dem Schlauch 2 fest verbunden ist.In Fig. 1, 1 denotes the guide catheter, which is on his front part at 2a with the hose 2 is firmly connected.

Im hinteren Bereich des Katheters besteht zwischen dem Führungskatheter 1 und dem Schlauch 2 ein Zwischenraum 6, so daß hier der Schlauch 2 frei beweglich ist.In the rear area of the catheter there is between the guide catheter 1 and the hose 2 an intermediate space 6, so that the hose 2 can move freely here is.

Mit 5a ist die Ausbauchung des Schlauches 2 bezeichnet. Im Bereich dieser Ausbauchung besteht der Schlauch 2 aus einzelnen Lamellen 4, die vorgeformt sein können, so daß sie normalerweise die in Fig. 1 gezeigte Lage einnehmen und die Ausbauchung 5a bilden.The bulge of the hose 2 is denoted by 5a. In the area This bulge consists of the tube 2 from individual lamellae 4, which are preformed can be so that they normally take the position shown in Fig. 1 and form the bulge 5a.

Durch Ziehen am freien Ende des Schlauches 2 werden die Lamellen 4 gestreckt, so daß der Durchmesser der Ausbauchung verringert werden kann. Diese Durchmesserverringerung der Ausbauchung wird beim Einführen des Katheters durch Ziehen am freien Ende des Schlauches 2 bewirkt. Nach dem Einführen des Katheters in ein Gefäß, in die Luftröhre oder dergleichen wird das freie Schlauchende wieder losgelassen, wodurch die Ausbauchung den in Fig. 1 gezeigten Umfang wieder einnimmt und sich gegen die Gefäßwandung oder dergleichen anlegt und damit eine sichere Abdichtung bewirkt.By pulling on the free end of the hose 2, the fins 4 stretched so that the diameter of the bulge can be reduced. These Reduction in diameter of the bulge occurs when the catheter is inserted Pulling on the free end of the hose 2 causes. After inserting the catheter the free end of the tube is placed in a vessel, in the windpipe or the like again released, whereby the bulge assumes the extent shown in Fig. 1 again and rests against the vessel wall or the like and thus a secure seal causes.

Zweckmäßig werden die einzelnen Lamellen 4 durch Längsschlitze in dem Schlauch 2 gebildet. Die Lamellen sind vorzugsweise von einer hochelastischen Folie umgeben.The individual slats 4 are expediently through longitudinal slots in the tube 2 is formed. The lamellas are preferably of a highly elastic one Surround foil.

Bei dem Ausführungsbeispiel nach Fig. 2 ist in den Schlauch 2 im Bereich der Ausbauchung 5 ein Ring 7 aus geschäumtem Material eingesetzt, welcher den Schlauch 2 ausbaucht. Der Schlauch 2 selbst muß also in diesem Falle im Bereich der Ausbauchung nicht vorgeformt sein. Das geschäumte Material soll hochelastisch sein, so daß es durch einen Zug am freien Ende des Schlauches 2 verformt werden kann, so daß die Ausbauchung in ihrem Durchmesser verkleinert werden kann.In the embodiment according to FIG. 2, the hose 2 is in the area the bulge 5 a ring 7 made of foamed material is used, which the hose 2 bulges. The hose 2 itself must in this case in the area of the bulge not be preformed. The foamed material should be highly elastic, so that it can be deformed by a train at the free end of the tube 2, so that the Bulge can be reduced in diameter.

Der Schlauch 2 kann auch bei dem Ausführungsbeispiel nach Fig. 2 im Bereich der Ausbauchung durch Lamellen gebildet sein, die auch hier durch Längsschlitze im Schlauch hergestellt sein können.The hose 2 can also in the embodiment of FIG The area of the bulge can be formed by lamellae, which are also formed here by longitudinal slots can be made in the tube.

In diesem Falle wird entweder auch hier um die Lamellen herum eine hochelastische Folie gelegt, oder es werden die Zwischenräume zwischen den Lamellen durch das geschäumte Material, das luftundurchlässig sein soll, ausgefüllt, wodurch auch in diesem Falle eine sichere Abdichtung gewährleistet wird.In this case, either a highly elastic film is placed, or the spaces between the slats are used by the foamed material, which should be impermeable to air, filled, whereby a secure seal is also guaranteed in this case.

Im übrigen kann der Katheter gemäß den Merkmalen des Hauptpatents ausgebildet sein.In addition, the catheter can according to the features of the main patent be trained.
