Abstract

Catheter for artificial insemination of farm animals comprises a catheter tube whose inner surface in the proximal end zone deviates from a cylindrical form for purposes of attaching the catheter to the nozzle of a sperm tube.

Description

Die Erfindung bezieht sich auf ein wenigstens zweiteiliges Inseminationsbesteck für die künstliche Besamung von Nutztieren, insbesondere Schweinen, umfassend einen Besamungskatheter mit einem Katheterschaft, bestehend aus einem Kunststoffrohr mit einer Verdickung am distalen Ende, und ein Gegenstück hierzu, nämlich eine Spermatube mit einer Abgabetülle, zur Aufnahme des zu applizierenden Spermas. Der Besamungskatheter hat ein distales Ende, das in die Vagina des Tiers eingeführt wird, und ein proximales Ende, an dem die Spermatube angesetzt wird.The invention relates to an at least two-part Inseminationsbesteck for the artificial insemination of livestock, especially pigs, comprising an insemination catheter with a catheter shaft consisting of a plastic tube with a thickening at the distal end, and a counterpart thereto, namely a Spermatube with a discharge spout, to Admission of the sperm to be applied. The insemination catheter has a distal end, which is inserted into the vagina of the animal and a proximal end where the sperm tube is attached.

Bei der künstlichen Besamung wird das zumeist bereits einige Tage alte oder aus tiefgefrorenem Lagerzustand aufgetaute Sperma einerseits möglichst sparsam, andererseits aber doch so reichlich, daß eine gute Befruchtungseffizienz erzielt wird, und außerdem möglichst schonend und ohne Druckstöße, die das Sperma schädigen könnten, appliziert. Bei der Schweinebesamung, bei der je Applikation relativ große Mengen an Sperma verabreicht werden müssen, wird das eingangs genannte Inseminationsbesteck verwendet, nämlich jeweils für den Einmalgebrauch ein Besamungskatheter und eine Spermatube. Diese Teile und deren Verwendung sind an sich bekannt, beispielsweise beschreibt DE 91 13 536 U Konstruktionen der Spermatube, EP 1 169 978 A1 Konstruktionen des Besamungskatheters und DE 200 15 979 U die Kombination der beiden Teile als Inseminationsbesteck.In artificial insemination, the usually already several days old or thawed from frozen storage condition sperm on the one hand as sparingly as possible, but on the other hand so abundant that a good fertilization efficiency is achieved, and also as gently as possible and without pressure surges that could damage the sperm applied. In pig insemination, in which each application relatively large amounts of sperm must be administered, the insemination cutler mentioned above is used, namely in each case for single use an insemination catheter and a sperm tube. These parts and their use are known per se, for example, describes DE 91 13 536 U Constructions of Spermatube, EP 1 169 978 A1 Constructions of the insemination catheter and DE 200 15 979 U the combination of the two parts as Inseminationbesteck.

Der übliche Besamungskatheter besteht aus einem etwa 50 cm langen Kunststoffrohr mit einem Außendurchmesser von 7 mm und einem Innendurchmesser von 5 mm, das an seiner distalen Spitze einen auf die Anatomie des Schweins abgestimmten verdickten Kopf, insbesondere einen Schaumstoffkörper, aufweist. Die Tuben sind üblicherweise Tuben aus einem flexiblen Kunststoff, insbesondere aus Polyäthylen niedriger Dichte, mit einem Füllungsvolumen in der Größenordnung von bis zu 100 ml. Zur Durchführung der Besamung werden die Tube und der Katheter gekoppelt, indem in das hintere, proximale Rohrende des in situ befindlichen Besamungskatheters die Tülle der Spermatube eingesteckt wird, nachdem die Tüllenspitze abgetrennt worden ist, und wird der Tubeninhalt durch den Katheter hindurch appliziert. Zum schonenden Einführen des Tubeninhalts wird beispielsweise das nach außen überstehende Stück des Katheterschafts leicht nach oben gebogen, so daß der Tubeninhalt durch die Schwerkraft weiterbefördert wird. Für diese Einführung wird ihm ausreichend Zeit gelassen. Es ergibt sich nun, daß die Koppelung der Tube am Katheterende, wenn sie nun durch das Einstecken der konischen Tülle in den Katheterschaft bewirkt wird, Probleme bereitet, die dadurch verstärkt werden, daß das Schwein dazu neigt, durch Wedeln mit dem Schwanz die Tube vom Katheter zu schlagen. Bei einem Inseminationsbesteck für die Rinderbesamung ist es bekannt ( DE 1616899 A ), daß der Spermabehälter an seinem auf den Besamungskatheter aufsetzbaren Ende mit einem Außengewinde versehen und in das mit entsprechendem Innengewinde versehene Ende des Katheters einschraubbar ist. Eine solche Ausführung verhindert zwar das unbeabsichtigte Lösen der Spermatube vom Katheter, sie ist jedoch in der Herstellung für ein Besteck zum Einmalgebrauch zu aufwendig.The usual insemination catheter consists of a about 50 cm long plastic tube with an outer diameter of 7 mm and an inner diameter of 5 mm, which has at its distal tip a tuned to the anatomy of the pig thickened head, in particular a foam body. The tubes are usually tubes made of a flexible plastic, in particular of low density polyethylene, with a filling volume of the order of up to 100 ml. To carry out the insemination, the tube and the catheter are coupled by inserting into the rear, proximal end of the tube in situ the sperm tube is inserted after the tip of the tulip has been severed, and the contents of the tube are applied through the catheter. For gentle insertion of the tube contents, for example, the protruding outward piece of the catheter shaft is slightly bent upwards, so that the tube contents is conveyed by gravity. He will be allowed enough time for this introduction. It now appears that the coupling of the tube at the catheter end, if now by the insertion of the conical spout into the catheter shaft poses problems that are exacerbated by the fact that the pig tends to beat the tube from the catheter by tail wagging. With a insemination kit for bovine insemination it is known ( DE 1616899 A ), that the sperm container is provided at its end placed on the insemination catheter end with an external thread and screwed into the corresponding female threaded end of the catheter. While such an embodiment prevents inadvertent disengagement of the sperm tube from the catheter, it is too expensive to manufacture for single-use cutlery.

Bei der Abfassung der zweiteiligen Form des Anspruchs 1 ist von diesem Dokument ausgegangen.When writing the two-part form of claim 1 is based on this document.

Durch die Erfindung soll ein Inseminationsbesteck geschaffen werden, das mit kleinerem Aufwand herstellbar ist und das Halten der Spermatube am proximalen Katheterende erleichtert. Dies wird, ausgehend von einem Inseminationsbesteck mit einem Innengewinde im Katheterschaft, dadurch erreicht, daß die Abgabetülle der Tube von ursprünglich glatter Außenfläche ist und durch Eindrehen in das Innengewinde des Katheterschafts zur Bildung eines Außengewindes verformbar ist. Durch diese Maßnahme ergibt sich mit nur einem einzigen vorgeschnittenen Gewinde ein formschlüssiger Halt der Abgabetülle der Tube im Katheterschaft und dadurch ein ausreichend stabiler Halt, der dem Besamer die Handhabung des Besamungsvorgangs insbesondere bei einer zeitlich ausgedehnteren Applikation erleichtert. Insbesondere bei passender Materialgestaltung und Gestaltung des Gewindes als Spitzgewinde braucht nämlich die Abgabetülle der Spermatube nicht besonders bearbeitet zu sein, das Gewinde des Katheterschafts erzeugt von selbst beim Eindrehen der Abgabetülle an dieser eine komplementäre elastische Formänderung, die eine ausreichend dichte Anlage am Gewinde des Katheterschafts zur Folge hat, um ein Aussickern von Spermaflüssigkeit zu verhindern.By the invention, an insemination cutlery is to be created, which can be produced with less effort and facilitates the retention of the sperm tube at the proximal end of the catheter. This is achieved, starting from an Inseminationsbesteck with an internal thread in the catheter shaft, characterized in that the dispensing spout of the tube is originally smooth outer surface and is deformable by screwing into the internal thread of the catheter shaft to form an external thread. By this measure, with only a single pre-cut thread results in a positive retention of the dispensing spout of the tube in the catheter shaft and thus a sufficiently stable hold, which facilitates the Besamer handling of the insemination process, especially at a time-extended application. In particular, with appropriate material design and design of the thread as a pointed thread namely the dispensing spout Spermatube not to be specially processed, the thread of the catheter shaft generated by itself when screwing the dispensing spout on this a complementary elastic deformation, which is a sufficiently tight contact with the thread of the catheter shaft Consequence, to prevent seepage of sperm fluid.

Eine geeignete Materialgegenüberstellung ist hierbei Polypropylen/Polyäthylen. Das Polyäthylen als Material für die Tube ist ausreichend elastisch, um sich an die Gewindegänge anzuschmiegen, und ist außerdem spermaverträglich, gut bearbeitbar, und beispielsweise durch ein Hitzeimpulsverfahren, ein Infrarotverfahren oder durch Ultraschallschweißung leicht verschließbar. Polypropylen ist demgegenüber härter und ist obendrein biegbar bei guter Knickfestigkeit. An sich käme auch Hart-PVC in Frage, dieses hat aber eine mangelhafte Knickfestigkeit. Das Gewinde kann in Abhängigkeit vom Schaft-Innendurchmesser z. B. ein Standard-M6-Gewinde sein, mit einer Gewindesteigung in der Größenordnung von 1 mm und einer Gewindetiefe in der Größenordnung von 0,6 mm. Es kann - unter der Voraussetzung, daß die Länge der Abgabentülle 28 mm beträgt - 10 bis 20 mm weit in den Katheterschaft eingeschnitten sein. Jedenfalls soll die Innengewindelänge nicht die Länge der Abgabetülle überschreiten, da jenseits von deren Mündung eine glatte Katheter-Innenwand zu bevorzugen ist.A suitable material comparison here is polypropylene / polyethylene. The polyethylene as a material for the tube is sufficiently elastic to conform to the threads, and is also semi-submissive, well workable, and, for example, by a heat impulse method, an infrared method or easily closed by ultrasonic welding. In contrast, polypropylene is harder and is also bendable with good kink resistance. In itself, hard PVC would come into question, but this has a poor kink resistance. The thread can, depending on the shaft inner diameter z. Example, a standard M6 thread, with a pitch in the order of 1 mm and a thread depth in the order of 0.6 mm. It may be cut 10 to 20 mm into the catheter shaft, provided that the length of the spout is 28 mm. In any case, the internal thread length should not exceed the length of the dispensing spout, as beyond the mouth of a smooth inner catheter wall is preferable.

Da jeder Katheter nur für den Einmalgebrauch bestimmt ist, darf die Anbringung der Formabweichung, insbesondere des Gewindes, keinen großen Aufwand erfordern. In das Katheterrohr aus Polypropylen wird das Gewinde mit Hilfe eines Metalldorns mit Gewindeschneidkämmen, mit einem Dorndurchmesser von 5 mm und mit einem Abstand von 1 mm zwischen den Kämmen, eingeschnitten. Die entstehenden Materialspäne werden mit dem Herausdrehen des Metallbolzens wieder entfernt. Der Vorgang läßt sich leicht automatisieren, was für die Durchführung der Erfindung vorteilhaft ist.Since each catheter is intended for single use, the attachment of the shape deviation, in particular the thread must not require much effort. In the polypropylene catheter tube, the thread is cut by means of a metal mandrel with threading combs, with a mandrel diameter of 5 mm and a distance of 1 mm between the combs. The resulting material chips are removed by unscrewing the metal bolt again. The process is easy to automate, which is advantageous for carrying out the invention.

Zur künstlichen Besamung eines in Fig. 1 anhand einer Schnittdarstellung angedeuteten Schweins ist ein Besamungskatheter 1, der aus einem Katheterschaft 2 und einem an dessen distaler Spitze sitzenden Formkörper 3 besteht, in die Vagina 4 des Schweins bis zur Cervix 5 eingeführt. Der Katheterschaft besteht aus einem etwa 50 cm langen Rohr aus Polypropylen mit einem Außendurchmesser von 7 mm, einer Wandstärke von 1 mm und einem Innendurchmesser von 5 mm.For artificial insemination of an in Fig. 1 an insemination catheter 1 which consists of a catheter shaft 2 and a molded body 3 seated at the distal tip thereof is inserted into the vagina 4 of the pig as far as the cervix 5 on the basis of a sectional view of the pig. The catheter shaft consists of a tube about 50 cm long made of polypropylene with an outer diameter of 7 mm, a wall thickness of 1 mm and an inner diameter of 5 mm.

Die zu applizierenden Spermien werden in einer Spermatube 9 herangebracht. Die Spermatuben 9 bestehen jeweils aus einem Behälterteil 10 und einer Abgabetülle 11. Beim dargestellten Modell hat die gesamte Spermatube 9 eine Länge von 172 mm. Die Abgabetülle 11 ist 28 mm lang und leicht konisch ausgebildet, indem sie an ihrem Fußpunkt einen Außendurchmesser von 5 mm und an ihrer Spitze einen Außendurchmesser von 3 mm hat. Die Abgabetülle 11 ist vorne an der Spitze geschlossen. An die Spitze schließt sich nach vorne noch eine etwa hammerförmige Verbreiterung 13 (Fig. 2) an, die als Stapelhilfe beim Stapeln der zunächst noch leeren Tuben dient, indem sie verhindert, daß beim Stapeln die konischen Tüllen ineinandergesteckt werden und sich dann nur noch schwer trennen lassen. Die Tülle 11, die ja dem Abgeben des Tubeninhalts dient, ist innen hohl, während der Verschlußkörper 13 massiv ist. Die Teile 10, 11 und 13 stellen zusammen ein einstückiges flexibles Kunststoff-Spritzgußstück, ein in Blastechnik hergestelltes Element oder ein in einem kombinierten Spritz-Blas-Verfahren hergestelltes Element aus Polyäthylen niedriger Dichte dar.The sperm to be administered are brought into a Spermatube 9. The Spermatuben 9 each consist of a container part 10 and a discharge spout 11. In the illustrated model, the entire Spermatube 9 has a length of 172 mm. The dispensing spout 11 is 28 mm long and slightly conical, having an outer diameter of 5 mm at its base and an outer diameter of 3 mm at its tip. The discharge spout 11 is closed at the front at the top. At the top, a hammer-shaped widening 13 closes towards the front ( Fig. 2 ), which serves as a stacking aid when stacking the initially empty tubes by preventing the conical grommets are inserted into each other during stacking and then can only be difficult to separate. The spout 11, which indeed serves to dispense the tube contents, is hollow inside, while the closure body 13 is solid. The parts 10, 11 and 13 together constitute a one-piece flexible plastic injection-molded part, a blow-molded element or a low-density polyethylene element produced by a combined injection-blown process.

Wie Fig. 2 zeigt, bricht oder schneidet der Besamer vor dem Besamungsvorgang die Tüllenspitze mit der Verbreiterung 13 ab, wie durch eine Schere symbolisiert ist.As Fig. 2 shows, breaks or cuts the Besamer before Besamungsvorgang the Tüllenspitze with the widening 13 from, as symbolized by a pair of scissors.

Zur stabilen Ankoppelung der Spermatube 9 an den Besamungskatheter 1 ist in das proximale Ende 14 des Katheterschafts 2 ein Innengewinde 15, nämlich ein Spitzgewinde, eingeschnitten. Das Innengewinde hat eine axiale Länge in der Größenordnung von 10 bis 15 mm und ist entsprechend dem Innendurchmesser ein M6-Gewinde, mit einem Durchmesser der Gewindegangscheitel von praktisch 5 mm. Die Abgabetülle 11 wird zunächst bis zum Anschlag eingeschoben und dann weiter eingedreht, wobei das weiche Tüllenmaterial durch die Gewindegänge verdrängt wird und sich durch elastische Formänderung in der tubennäheren Hälfte der Tülle 11 ein vorübergehendes Gegengewinde bildet, durch das der Halt der Spermatube 9 am Besamungskatheter 1 in ausreichender Weise sichergestellt wird. Es hat sich erwiesen, daß auch durch einen Schlag mit dem Schweineschwanz die so angekoppelte Tube 9 nicht aus dem Katheter 1 herausgeschlagen wird.For stable coupling of the sperm tube 9 to the insemination catheter 1, an internal thread 15, namely a pointed thread, is cut into the proximal end 14 of the catheter shaft 2. The internal thread has an axial length of the order of 10 to 15 mm and is corresponding to the Inner diameter M6 thread, with a thread crest diameter of practically 5 mm. The dispensing spout 11 is first inserted as far as the stop and then further screwed in, wherein the soft spout material is displaced by the threads and forms by elastic deformation in the tube proximal half of the spout 11 a temporary counter thread, through which the maintenance of Spermatube 9 on insemination catheter. 1 is ensured in a sufficient manner. It has been found that even with a hit with the pig's tail, the so-coupled tube 9 is not knocked out of the catheter 1.

Der Gewindestandard M6 hat sich für das spezielle Schweineinseminationsbesteck als sehr wirksam erwiesen. Es stellt jedoch nicht die einzige Ausführungsmöglichkeit dar. In Abhängigkeit vom Rohrdurchmesser, von der Wandstärke und den Materialien, aber auch bei der beschriebenen Dimensionierung können auch abweichende Gewindedimensionierungen, beispielsweise nicht-metrische Gewinde und andere Gewindesteigungen, zu einer ausreichenden Fixierung führen.Thread standard M6 has proven to be very effective for the special pig insemination kit. However, it does not represent the only possible embodiment. Depending on the pipe diameter, the wall thickness and the materials, but also in the described dimensioning and deviating threaded dimensions, such as non-metric threads and other thread pitches can lead to a sufficient fixation.
