Abstract

The valve comprises a ball (6) moving freely within a piece of tubing (1) inserted between two vein ends seals onto a sealing ring (8) within the tube in blood movement away from the heart as opposed to blood movement towards the heart in which case the seal (6) bears on parts (5) within the tube to allow blood flow to the heart. The tubing is preferably expanded in its central part (2) to allow free ball seal movement, using longitudinal ribs (3) in the tube arranged at peripheral spacing to form a cage cylinder (4) with waisted heart-facing end (5) to enclose the seal movement as specified. The ribs spread out again on leaving the end to give a steadily convex expanded part so the ribs start and end at the expansion ends. The specific gravity of the ball approximately equals that of the blood and the tube can contain a grid in its centre part so the ball can bear on this without restricting blood flow.

Description

Die Erfindung bezieht sich auf ein Venen-Ventil. Dieses er­ laubt nur einen herzwärts gerichteten Blutstrom.The invention relates to a vein valve. This he leaves only a cardiac flow.

Die natürlichen Venen-Ventile sind Klappen. Diese verlieren mit zunehmendem Alter eines Menschen häufig ihre Funktionsfä­ higkeit, was zu venösen Insuffizienzen wie Krampfadern führen kann. In schweren Fällen kann es sogar zum Verlust von Extre­ mitäten kommen.The natural vein valves are valves. Lose this their function often increases with the age of a person ability to cause venous insufficiency such as varicose veins can. In severe cases, it can even lead to the loss of extre come along.

Man kennt Operationsmethoden, um dieser Entwicklung entgegen­ zuwirken. Solche Operationen sind indessen sehr aufwendig und nicht immer erfolgreich.Surgical methods are known to counter this development to act. However, such operations are very complex and not always successful.

Der Erfindung liegt die Aufgabe zugrunde, ein Venen-Ventil zu schaffen, das möglichst einfach in eine Vene eingesetzt wer­ den kann und eine lange Lebensdauer besitzt. The invention has for its object to a vein valve create that as easily as possible inserted into a vein that can and has a long lifespan.  

Diese Aufgabe wird durch ein Venen-Ventil gelöst, wie es im Kennzeichen des Anspruchs 1 definiert ist.This task is solved by a vein valve, as in the Characteristic of claim 1 is defined.

Natürlich müssen die Abmessungen des Ventils solcher Art sein, daß ein ungehinderter Blutstrom zum Herzen hin gewähr­ leistet ist.Of course, the dimensions of the valve of this type be that an unimpeded flow of blood to the heart is accomplished.

Ein solches Venen-Ventil läßt sich einfach in die Venen ein­ bauen und ist weitgehend unbegrenzt haltbar.Such a vein valve can easily be inserted into the veins build and is largely unlimited.

Der Einsatz des erfindungsgemäßen Venen-Ventils erfolgt derart, daß man aus der Vene das Stück heraustrennt, in dem sich die Venenklappen befinden, und statt dessen das erfin­ dungsgemäße Venen-Ventil einsetzt. Das Rohrstück bzw. das ganze Ventil haben zweckmäßigerweise eine nicht unerhebliche Flexibilität. Aber auch ein relativ starres Rohrstück bzw. Ventil könnte zweckmäßig sein. Als Materialien kommen bevor­ zugt diejenigen Materialien in Frage, die auch bei Bypässen verwendet werden.The vein valve according to the invention is used in such a way that the piece is separated from the vein in which the venous valves are there, and instead invent this uses the appropriate vein valve. The pipe section or the whole valve expediently have a not inconsiderable one Flexibility. But also a relatively rigid piece of pipe or Valve could be useful. As materials come before considers those materials that are also used for bypasses be used.

Weitere Einzelheiten des erfindungsgemäßen Venen-Ventils er­ geben sich aus der Zeichnung.Further details of the vein valve according to the invention he give up from the drawing.

Fig. 1 einen Längsschnitt durch ein erfindungsgemäßes Venen- Ventil gemäß der Linie I-I der Fig. 2 und Fig. 1 shows a longitudinal section through a venous valve according to the invention along the line II of Fig. 2 and

Fig. 2 einen Schnitt durch das Venen-Ventil gemäß der Linie II-II der Fig. 1. Fig. 2 shows a section through the venous valve according to the line II-II in FIG. 1.

Das Venen-Ventil besteht aus einem Rohrstück 1, das in seinem mittleren Bereich eine Aufweitung 2 aufweist. In dieser be­ finden sich Rippen 3, die in ihrem in bezug auf Fig. 1 un­ teren Teil einen zylindrischen Käfig 4 bilden, der sich nach oben im Bereich 5 verengt. Darüber laufen die Rippen 3 wieder auseinander. In dem zylindrischen Teil 4 befindet sich eine Kugel 6, deren spezifisches Gewicht gleich dem spezifischen Gewicht des Blutes ist. Die Kugel 6 schwebt also in dem Blut und wird lediglich durch den Blutströmungsdruck bewegt. Ist der Blutstrom herzwärts gerichtet (siehe Pfeil 7 in Fig. 1), wird die Kugel 6 nach oben in den verengten Bereich 5 des von den Rippen 3 gebildeten Käfigs 4 gedrückt. Das Blut kann so­ mit ungehindert durch das Ventil hindurchströmen. Bei einem Blutdruck in umgekehrter Richtung legt sich die Kugel 6 an einen Sitz 8 und verschließt damit das Ventil.The vein valve consists of a pipe section 1 which has an expansion 2 in its central region. In this be there are ribs 3 which form a cylindrical cage 4 in their lower part with respect to FIG. 1, which narrows upwards in region 5 . The ribs 3 diverge again. In the cylindrical part 4 there is a ball 6 , the specific weight of which is equal to the specific weight of the blood. The ball 6 thus hovers in the blood and is only moved by the blood flow pressure. If the blood flow is directed towards the heart (see arrow 7 in FIG. 1), the ball 6 is pressed upwards into the narrowed area 5 of the cage 4 formed by the ribs 3 . The blood can flow through the valve unhindered. At a blood pressure in the opposite direction, the ball 6 lies on a seat 8 and thus closes the valve.

Natürlich kann das erfindungsgemäße Ventil auch zwischen zwei Bypass-Enden oder einem Venenende und einem Bypass-Ende liegen.Of course, the valve according to the invention can also be between two Bypass ends or a vein end and a bypass end.
