Abstract
Description
Die Erfindung betrifft einen Besamungskatheter für Tiere, insbesondere für Schweine, mit einem langgestreckten, biegeelastischen Injektionsrohr, das an seinem vorderen, in den Uterus des Tieres einführbaren Ende mit einem weichelastischen Führungspfropfen versehen ist. Die Erfindung ist ferner auf ein Verfahren zur Herstellung eines solchen Katheters gerichtet.The invention relates to an insemination catheter for animals, in particular for pigs, with an elongated, flexurally elastic Injection tube, which is at its anterior, in the uterus of the Animal insertable end with a soft elastic guide plug is provided. The invention is also based on a method directed to the manufacture of such a catheter.
Derartige Katheter werden für die künstliche Besamung von Nutz-Haustieren, beispielsweise von Schweinen verwendet. Der weichelastische Führungspfropfen dient dazu, beim Einführen des Katheters Verletzungen des Uterus sicher zu vermeiden. Das langgestreckte Injektionsrohr, durch das nach Einführen des Katheters die Samenflüssigkeit injiziert wird, muß zwar biegeelastisch sein, soll dabei jedoch eine Mindest-Biegesteifigkeit haben, die gewährleistet, daß das Rohr beim Einführen nicht abknicken kann, so daß sichergestellt ist, daß der Katheter mit seinem vorderen Ende genügend tief in den Uterus des Tieres einschiebbar ist und dabei auch für die zu injizierende Samenflüssigkeit durchgängig bleibt.Such catheters are used for artificial insemination of domestic animals, used for example by pigs. The soft elastic Guide plug is used when inserting the catheter Avoid injury to the uterus safely. The elongated Injection tube through which after insertion of the catheter The semen is injected, but must be flexible should have a minimum bending stiffness, however ensures that the tube cannot kink when inserted, so that it is ensured that the catheter with its front Insertable deep enough into the animal's uterus and also for the seminal fluid to be injected remains.
Bei diesen Kathetern ist neben der geforderten Mindeststeifigkeit des Injektionsrohres auch die Haftung des Führungspfropfens am Rohr von besonderer Wichtigkeit. Es darf nämlich unter keinen Umständen dazu kommen, daß sich der Pfropfen vom vorderen Ende des Injektionsrohres löst, da er in einem solchen Fall nur operativ aus dem Uterus des Tieres entfernt werden kann. Auch kann es zu Verletzungen durch die harte, vordere Kante des Injektionsrohres kommen, wenn sich der Pfropfen beim Einführen in den Uterus auf dem Röhrchen verschiebt und nach hinten verrutscht.These catheters have the required minimum stiffness of the injection tube also the adhesion of the guide plug of particular importance on the pipe. It is not allowed under any Circumstances may come up that the plug comes off the front end of the injection tube, since in such a case it is only operative can be removed from the animal's uterus. Can too injuries from the hard front edge of the injection tube come when the plug is inserted into the The uterus moves on the tube and slips backwards.
Als Material für den Führungspfropfen hat sich ein Polyurethan-Weichschaum als ganz besonders vorteilhaft erwiesen, der die Anforderungen an die Hygiene, Formstabilität bei gleichzeitiger Nachgiebigkeit und Verarbeitbarkeit zu den verschiedenen, erforderlichen Formen des Pfropfens bestens erfüllt.A flexible polyurethane foam has become the material for the guide plug proven to be particularly advantageous in meeting the requirements in terms of hygiene, dimensional stability with simultaneous Compliancy and processability to the different, required Forms of grafting perfectly fulfilled.
Als Werkstoffe für das Injektionsröhrchen kommen grundsätzlich verschiedene Kunststoffe in Betracht. Unter dem Gesichtspunkt der geforderten Biegesteifigkeit des Rohres und der Wirtschaftlichkeit bei seiner Herstellung haben sich Rohre aus Polypropylen als besonders vorteilhaft erwiesen. Von Nachteil bei diesem Werkstoff ist es jedoch, daß bislang eine zufriedenstellende Haftung zwischen Polyurethan und Polypropylen nicht erreicht wurde, wenn der Führungspfropfen direkt am Injektionsrohr aus Polypropylen angeschäumt wurde. Vielmehr war es bei dieser Werkstoffpaarung bislang erforderlich, den Führungspfropfen separat herzustellen und dann unter Verwendung eines geeigneten Klebstoffes am Injektionsrohr anzukleben. Diese Vorgehensweise ist sehr arbeitsaufwendig und kostenintensiv. Auch Rohre aus anderen Kunststoffen wie beispielsweise aus Polyethylen bieten nicht die erforderliche Haftung eines direkt angeschäumten Polyurethan-pfropfens, insbesondere dann nicht, wenn Feuchtigkeit an die Verbindungsstelle der beiden Teile gelangt. Allein bei Verwendung eines Rohres aus Polyvinylchlorid konnte eine zufriedenstellende Haftung des daran direkt angeschäumten Polyurethan-pfropfens sichergestellt werden, jedoch ist PVC als Werkstoff für die Verwendung im veterinärmedizinischen Bereich, insbesondere aus ökologischen Gesichtspunkten unerwünscht.Basically come as materials for the injection tube different plastics. From the point of view the required bending stiffness of the pipe and the economy During its manufacture, polypropylene pipes were used proven to be particularly advantageous. A disadvantage of this However, it is material that has so far been satisfactory Adhesion between polyurethane and polypropylene not achieved was when the guide plug came off directly on the injection tube Polypropylene was foamed. Rather, it was with this pairing of materials Previously required, the guide plug separately and then using a suitable adhesive to stick to the injection tube. This procedure is very labor-intensive and expensive. Even pipes from others Plastics such as polyethylene do not offer that required adhesion of a directly foamed polyurethane plug, especially not when moisture is on the Junction of the two parts. Alone when used a pipe made of polyvinyl chloride could be satisfactory Adhesion of the directly plugged polyurethane plug be ensured, however PVC is a material for use in the veterinary field, in particular undesirable from an ecological point of view.
Aufgabe der Erfindung ist es, einen Besamungskatheter der eingangs genannten Art zu schaffen, bei eine sichere Verbindung zwischen Injektionsrohr und Führungspfropfen ohne zusätzliche Klebstoffe oder dergleichen sichergestellt ist. The object of the invention is to provide an insemination catheter to create the type mentioned, with a secure connection between injection tube and guide plug without additional Adhesives or the like is ensured.
Diese Aufgabe wird mit der Erfindung dadurch gelöst, daß das Injektionsrohr im Verbindungsbereich zu dem Führungspfropfen mechanisch angerauht ist und daß der Führungspfropfen aus Polyurethanschaum besteht und direkt an das Injektionsrohr an dessen mechanisch aufgerauhter Oberfläche angeschäumt ist. Das Injektionsrohr kann dabei vorteilhaft aus Polypropylen, aus Polyethylen oder Mischungen aus den beiden Materialien oder auch aus einem Coextrudat eines inneren Polypropylenrohres und einer äußeren Polymerbeschichtung bestehen.This object is achieved with the invention in that the injection tube mechanically in the connection area to the guide plug is roughened and that the guide plug made of polyurethane foam exists and directly to the injection tube at its mechanically roughened surface is foamed. The injection tube can advantageously be made of polypropylene, of polyethylene or mixtures of the two materials or also from a coextrudate of an inner polypropylene tube and one outer polymer coating.
Es hat sich gezeigt, daß durch ein mechanisches Anrauhen der Oberfläche des Injektionsrohres im Verbindundungsbereich zu dem später angeschäumten Pfropfen zwischen den beiden Teilen des Katheters eine ganz ausgezeichnete Haftung erreicht wird, wie sie bislang nur erzielt werden konnte, wenn der Pfropfen separat hergestellt und anschließend mittels eines geeigneten Klebers am Injektionsrohr angeklebt wird. Offenbar ermöglicht es die mechanisch aufgerauhte Oberfläche des Injektionsrohres dem Polyurethanschaum, in die durch das Anrauhen entstandenen Vertiefungen u.dgl. einzudringen und sich so praktisch formschlüssig mit dem Rohr zu verbinden. Durch die mechanische Vorbehandlung wird die Rauhtiefe der Rohroberfläche im Verbindungsbereich bewußt vergrößert und somit die gewünschte, ausgezeichnete Haftung erreicht, die auch dann noch gegeben ist, wenn Feuchtigkeit an die Verbindungsstelle beide Katheterteile gelangt, was bei den bisherigen Versuchen mit direkt angeschäumten Führungspfropfen regelmäßig zu Haftungsproblemen führte.It has been shown that by mechanical roughening Surface of the injection pipe in the connection area to the later foamed plug between the two parts of the catheter a very excellent liability is achieved as they So far it could only be achieved if the plug was separated manufactured and then using a suitable adhesive on Injection tube is glued. Apparently it enables the mechanical roughened surface of the injection tube the polyurethane foam, into the depressions created by the roughening and the like penetrate and so practically form-fitting to connect the pipe. Due to the mechanical pretreatment aware of the roughness of the pipe surface in the connection area enlarged and thus achieves the desired, excellent adhesion, which is still there when moisture is on the Connection point reaches both parts of the catheter, which is the case with the previous ones Try regularly with directly foamed guide plugs led to liability problems.
Die Rauhtiefe oder Riefentiefe beträgt nach dem mechanischen Anrauhen der Oberfläche des Injektionsrohres vorzugsweise zwischen 0,01 und 0,1 mm. Vorzugsweise ist das Injektionsrohr im Verbindungsbereich durch Schleifen angerauht, was beispielsweise mit einem Schleifstein, einer Schleifscheibe oder dergleichen geschehen kann. Es ist auch möglich, die mechanisch angerauhte Oberfläche durch mindestens eine Eindrehung oder Nute im Verbindungsbereich des Injektionsrohres herzustellen bzw. eine solche Eindrehung oder Nute zusätzlich zum Anrauhen durch Schleifen der Rohroberfläche vorzusehen. Die Eindrehung oder Nute erzeugt gleichfalls eine Vertiefung, in die der Polyurethanschaum hineinschäumen kann, um so eine formschlüssige Verbindung zwischen sich und dem Injektionsrohr zu schaffen.The surface roughness or groove depth after mechanical roughening is the surface of the injection tube preferably between 0.01 and 0.1 mm. The injection tube is preferably in the connection area roughened by grinding, for example with a grindstone, a grinding wheel or the like can. It is also possible to use the mechanically roughened Surface by at least one indentation or groove in the connection area to produce the injection tube or such Turning or grooving in addition to roughening by grinding the To provide pipe surface. The recess or groove creates likewise a depression into which the polyurethane foam foams can create a positive connection between yourself and the injection tube.
Um die Haftung zwischen dem Weichschaumpropfen und dem Injektionsrohr noch weiter zu verbessern, ist es vorteilhaft, wenn das Injektionsrohr zusätzlich zu dem mechanischen Anrauhen seiner Oberfläche einer chemischen Vorbehandlung unterworfen ist, was beispielsweise durch eine Coronabehandlung, durch Beflämmung, durch Ätzen oder durch Fluorierung des vorderen Rohrendes geschehen kann. Diese chemische Vorbehandlung erfolgt vorzugsweise nach dem mechanischen Anrauhen der Oberfläche.The adhesion between the soft foam plug and the injection tube To improve still further, it is beneficial if that Injection tube in addition to the mechanical roughening of his Surface is subjected to a chemical pretreatment for example by corona treatment, by flame treatment, by etching or by fluorination of the front pipe end can happen. This chemical pretreatment is preferably carried out after mechanical roughening of the surface.
Zur Herstellung eines solchen Besamungskatheters hat sich ein Verfahren als besonders vorteilhaft erwiesen, bei dem ein langgestrecktes, biegeelastisches Injektionsrohr vorzugsweise aus Polypropylen, Polyethylen oder Mischungen hiervon oder auch aus einem Coextrudat von Polypropylen und einem Polymer an seinem einen, einen Verbindungsbereich bildenden Ende zuerst mechanisch aufgerauht wird und anschließend mit seinem mechanisch angerauhten Verbindungsbereich in eine Form eingeführt wird, woraufhin eine sich verfestigende Polyurethanmasse in die Form injiziert wird, um so einen direkt an das Injektionsrohr angeschäumten Führungspfropfen auszubilden. Wie bereits erwähnt, kann das Injektionsrohr dabei vor dem Einführen in die Form an seinem Endbereich chemisch vorbehandelt werden, was zweckmäßig durch eine Coronabehandlung geschieht, wodurch die mechanisch bereits angerauhte Oberfläche oxidiert und so eine noch größere Haftfestigkeit erzeugt wird. Alternativ ist es natürlich auch möglich, die Behandlung der Oberfläche des Rohres durch Beflämmung zu erreichen oder das Rohr zu fluorieren oder anzuätzen. Die mechanische Vorbehandlung des Injektionsrohres im Verbindungsbereich kann durch Schleifen, beispielsweise mit einer Schleifscheibe oder einem Schleifstein geschehen; alternativ oder zusätzlich kann das Rohr in seinem Verbindungsbereich auch eine Eindrehung oder Nut erhalten, die mittels eines geeigneten Drehwerkzeuges hergestellt werden kann.There has been a decision to manufacture such a insemination catheter Process proven to be particularly advantageous in which an elongated, flexible injection tube preferably from Polypropylene, polyethylene or mixtures thereof or also from a coextrudate of polypropylene and a polymer on its one end, which forms a connection area, first mechanically is roughened and then mechanically roughened connection area is inserted into a mold, whereupon a solidifying polyurethane mass in the mold is injected so as to foam directly onto the injection tube To train guide plugs. As already mentioned, the injection tube can be inserted into the mold its end region are chemically pretreated, which is appropriate done by a corona treatment, which makes the mechanical already roughened surface oxidized and thus an even larger one Adhesive strength is generated. Alternatively, of course it is possible treatment of the surface of the pipe by flame treatment to reach or to fluorinate or etch the pipe. The mechanical pretreatment of the injection pipe in the connection area can by grinding, for example with a Grinding wheel or a grindstone happen; alternatively or in addition, the pipe can also in its connection area a recess or groove obtained by means of a suitable Rotary tool can be manufactured.
