Description
Katheter mit Drahteinlage Zusatz zum Patent 823320 Durch das Patent 823 320 ist ein insbesondere zur Verwendung als Intratrachealkatheter bestimmter Katheter geschützt, bei welchem an das eine Ende des durch eine in Gummi oder Kunststoff eingebettete schraubenförmige Draht- oder Kunststoffeder gebildeten Katheterrohres eine Spitze nach Art einer Flötenspitze und an das andere Ende ein schlauchförmiges Anschlußstück angesetzt ist, wobei sämtliche Teile durch einen gemeinsam glatten Überzug aus Kautschuk oder elastischem Kunststoff miteinander verbunden sind.Catheter with wire insert Addition to patent 823320 By the patent 823 320 is a particular intended for use as an intratracheal catheter Catheter protected, at which one end of the by one in rubber or plastic embedded helical wire or plastic spring formed catheter tube one tip in the manner of a flute tip and at the other end a tube-shaped one Connection piece is attached, with all parts by a jointly smooth Cover made of rubber or elastic plastic are connected to one another.
Weiterhin bildet den Gegenstand des Hauptpatents ein Verfahren zur Herstellung dieser Katheter über einem geeigneten Dorn. Furthermore, the subject of the main patent forms a method for Manufacture this catheter over a suitable mandrel.
Die Erfindung betrifft eine weitere Ausgestaltung dieses Katheters und seines Herstellungsverfahrens in der Richtung, daß der Katheter als sog. Ballonkatheter mit aufblasbarer Luftblase ausgebildet wird. Erfindungsgemäß ist zu diesem Zwecke in eine in dem Katheterrohr angebrachte Längsrinne ein Luftschlauch eingeklebt, der innerhalb der Drahteinlage und des diese und die Katheterspitze überdeckenden glatten Überzuges liegt und durch eine die Wandung des Luftschlauches und des Überzuges durchsetzenden Querbohrung in an sich bekannter Weise in einen nahe der Spitze über das Ende des Katheterrohres geschobenen, aufblasbaren Ballon mündet. The invention relates to a further embodiment of this catheter and its manufacturing process in the direction that the catheter as a so-called balloon catheter is formed with an inflatable air bladder. According to the invention is for this purpose An air hose is glued into a longitudinal groove in the catheter tube, that within the wire insert and that covering it and the catheter tip smooth cover and through a wall of the air hose and the cover penetrating transverse bore in a manner known per se in a near the tip over the end of the catheter tube is pushed into the inflatable balloon.
Dadurch ist es möglich, den Katheter durch die Pressung des mehr oder wenig stark aufgeblasenen Ballons an der gewünschten Stelle in der Trachee festzuhalten.This makes it possible to push the catheter through the Pressing the more or less strongly inflated balloon at the desired location in the To hold on to the trachee.
Die Herstellung dieser Katheter erfolgt erfindungsgemäß in der Weise, daß zunächst über einem Dorn. mit Rinne durchTauchen oder Spritzen der innere Film des Katheterrohres hergestellt, dies er dann abgezogen und nach Pudern dann auf denselben Dorn mit Rinnen wieder aufgezogen und gereinigt wird, beispielsweise mit Benzin; sodann wird der unabhängig vom Katbeterrohr hergestellte dünne Luftschlauch in die über dem Dorn gebildete Rinne des Films eingelegt und eingeklebt und dann eine Spirale aus vorzugsweise flachem Metall- oder Kunststoffdraht übergezogen. Daran anschließend wird dann in der im Hauptpatent beschriebenen Weise eine flötenförmige Spitze aus Stoff oder Gummi angebracht, das vordere Ende des Luftschlauches, das mit einem Kontrollballon versehen sein kann, an dem herausstehenden. Dornende befestigt, so daß es nicht mit in die Lösung taucht, und nun der Katheter in eine Kautschuk- oder Kunststofflösung oder -dispersion eingetaucht, bis der Überzug die gewünschte Stärke erreicht hat. Schließlich wird der Katheter vom Dorn abgezogen, die Flötenspitze zwecks Bildung glatter Kanten gebrannt und abgerundet, oberhalb der Spitze eine Luftaustrittsöffnung im Luftschlauch und dem anschließenden. Uberzug angebracht, der ganze Katheter durch Bromieren oder ChlorierenL vollständig geglättet und zuletzt die aufblasbare Blase über den die Luftaustrittsöffnung enthaltenden Teil gezogen, wo sie durch ihre eigene Spannung festgehalten wird. According to the invention, these catheters are manufactured in such a way that that first about a thorn. with gutter by dipping or spraying the inner film made of the catheter tube, this he then pulled off and then on after powdering the same mandrel with grooves is pulled up again and cleaned, for example with Petrol; then the thin air hose produced independently of the catheter tube inserted and glued into the groove of the film formed over the mandrel and then a spiral of preferably flat metal or plastic wire is drawn over it. This is followed by a flute-shaped one in the manner described in the main patent Tip made of fabric or rubber attached to the front end of the air tube that can be provided with a control balloon on the protruding. End of the mandrel attached, so that it does not dip into the solution, and now the catheter in a rubber or plastic solution or dispersion immersed until the coating has the desired Has reached strength. Finally the catheter is withdrawn from the mandrel, the tip of the flute Burned and rounded to create smooth edges, one above the tip Air outlet opening in the air hose and the subsequent. Cover attached, the whole catheter is completely smoothed by bromination or chlorination and finally the inflatable bladder is drawn over the part containing the air outlet opening, where it is held in place by its own tension.
Ein Ausführungsbeispiel eines Katheters nach der Erfindung ist nachstehend an Hand' der schematischen Zeichnung noch kurz erläutert. Dabei sind die mit dem Ausführungsbeispiel des Hauptpatents übereinstimmenden Teile mit gleichen Bezugs zeichen wie dort bezeichnet. An embodiment of a catheter according to the invention is shown below briefly explained on the basis of the schematic drawing. There are those with the Embodiment of the main patent matching parts with the same reference signs as indicated there.
Fig. I zeigt den fertigen Katheter mit übergezogenem Ballon in Ansicht und teilweise im Längsschnitt, Fig. 2 einen Querschnitt mit Dorn nach der Linie C-C, Fig. 3 einen Querschnitt nach der Linie D-D. Fig. I shows the finished catheter with the balloon pulled over in a view and partly in longitudinal section, FIG. 2 shows a cross section with a mandrel along the line C-C, Fig. 3 shows a cross section along the line D-D.
Der Katheter besteht aus dem Katheterrohr I und dem in eine Rinne 8 des Rohres eingeklebten Luftschlauch g sowie aus der Schraubenfeder 7, welche das Katheterrohr I und den Luftschlauch g umschließt und mit diesem zusammen in den Überzug 10 aus Kautschuk oder Kunststoff eingebettet ist, der zugleich die flötenartige Spitze 2 und das dieser gegenüberliegende, aus einem verhältnismäßig starkwandigen Gummirohr bestehende hintere Ende 3 umschließt und mit dem Hauptteil des Katheters verbindet. The catheter consists of the catheter tube I and the one in a channel 8 of the tube glued-in air hose g and from the helical spring 7, which the catheter tube I and the air tube g encloses and together with this in the coating 10 made of rubber or plastic is embedded, which is also the flute-like Tip 2 and the one opposite it, made of a relatively thick-walled one Rubber tube enclosing the rear end 3 and the main part of the catheter connects.
Am inneren Ende des Luftschlauches ist der äußere Überzug des Katheters mit einer Bohrung nI vers eher, durch welche die in den Luftschlauch eingeblasene Luft in den an dieser Stelle über den Katheter geschobenen Ballon 12 übertreten kann. At the inner end of the air tube is the outer coating of the catheter with a hole nI vers rather, through which the blown into the air hose Air into the balloon 12 pushed over the catheter at this point can.
I3 ist ein Kontrollballon bekannter Art, der in den freien Teil des Luftschlauches g eingeschaltet ist. Mit 14 ist der mit einer Längsrinne versehene Dorn bezeichnet, über welchem der Katheter hergestellt wird. I3 is a known type of control balloon that is inserted into the free part of the Air hose g is switched on. With 14 is provided with a longitudinal groove Mandrel designates over which the catheter is made.
