Abstract
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 auf das 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 insemination set for artificial insemination of farm animals, especially pigs, comprising a insemination catheter with a catheter shaft consisting of a plastic tube with a thickening at the distal end, and on the Counterpart to this, namely a sperm tube with a dispensing spout Recording the sperm to be applied. The insemination catheter has one distal end that is inserted into the animal's vagina and a proximal end End at which 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 UM Konstruktionen der Spermatube, EP 1 169 978 A1 Konstruktionen
des Besamungskatheters und DE 200 15 979 A die Kombination
der beiden Teile als Inseminationsbesteck.With artificial insemination it is usually a few days old
or semen thawed from frozen storage state on the one hand if possible
economical, but on the other hand so plentiful that good fertilization efficiency
is achieved, and also as gently as possible and without pressure surges,
that could damage the sperm. With the pig insemination, with
which have to be administered relatively large amounts of sperm per application,
the insemination set mentioned at the beginning is used, namely in each case
a single use insemination catheter and a sperm tube. This
Parts and their use are known per se, for example describes
DE 91 13 536 UM constructions of the sperm tube,
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 Tubenirlialts 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, nämlich die Verbindung der konischen Tülle mit dem Katheterschaft, Probleme bereitet, die dadurch verstärkt werden, daß das Schwein dazu neigt, durch Wedeln mit dem Schwanz die Tube vom Katheter zu schlagen.The usual insemination catheter consists of an approximately 50 cm long Plastic pipe with an outer diameter of 7 mm and an inner diameter of 5 mm, which at its distal tip matches the anatomy of the Pig's matched thickened head, especially a foam body, having. The tubes are usually made of a flexible tube Plastic, especially made of low density polyethylene, with a filling volume in the order of up to 100 ml. To carry out the Insemination, the tube and the catheter are coupled by placing in the rear, proximal tube end of the in situ insemination catheter the spout of the Spermatube is inserted after the tip of the spout has been separated, and the tube contents are applied through the catheter. To the Gentle insertion of the tube air tubing, for example, will be the outside protruding piece of the catheter shaft slightly bent upwards so that the Tube content is transported by gravity. For this introduction he is given enough time. It now emerges that the coupling of the Tube at the end of the catheter, namely the connection of the conical spout to the Catheterization, creates problems that are exacerbated by the fact that Pig tends to wiggle the tail of the tube from the catheter to beat.
Durch die Neuerung soll das Halten der Spermatube am proximalen Katheterende erleichtert werden. Dies wird dadurch erreicht, daß an der Innenwand des Katheterschafts im Bereich seines proximalen Endes von der Zylinderform abweichende Formen zum Festhalten der Abgabetülle der Tube gebildet sind und/oder daß an der Außenwand der Abgabetülle hinterschnittene Oberflächenformen zum Festhalten der Abgabetülle im Bereich des proximalen Endes des Katheterschafts gebildet sind. Durch solche Maßnahmen ergibt sich ein insbesondere 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.The innovation aims to hold the sperm tube at the proximal end of the catheter be relieved. This is achieved in that on the inner wall of the catheter shaft in the area of its proximal end from the cylindrical shape different shapes are formed to hold the dispensing spout of the tube and / or that undercut surface shapes on the outer wall of the dispensing spout to hold the dispensing nozzle in the area of the proximal End of the catheter shaft are formed. Such measures result in an especially positive hold of the delivery spout of the tube in the catheter shaft and thus a sufficiently stable hold that the inseminator handling of the insemination process, especially with a longer one Application made easier.
Eine aus Herstellungsgründen bevorzugte Verformung besteht darin, daß in das proximale Ende des Katheterschafts für eine kurze Strecke ein Innengewinde, eingeschnitten ist. Bei passender Materialgestaltung und Gestaltung des Gewindes als Spitzgewinde braucht dann die Abgabetülle der Spermatube nicht besonders bearbeitet zu werden, das Gewinde des Katheterschafts erzeugt von selbst beim Eindrehen der Abgabetülle an dieser eine komplementäre Formänderung.A preferred deformation for manufacturing reasons is that an internal thread for a short distance into the proximal end of the catheter shaft, is incised. With suitable material design and design of the Threads as pointed threads then do not need the sperm tube dispensing spout The thread of the catheter shaft to be specially machined even when screwing in the dispensing spout on this a complementary change in shape.
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 is polypropylene / polyethylene. The polyethylene as the material for the tube is sufficiently elastic to cling to the threads and is also sperm compatible, easy to work with, for example by a heat pulse process, an infrared process or easily sealed by ultrasonic welding. In contrast, polypropylene is harder and, on top of that, bendable with good Buckling strength. Hard PVC in itself could also be considered, but this has one poor kink resistance. The thread can vary depending on the inside diameter of the shaft z. B. be a standard M6 thread with a thread pitch in the order of 1 mm and a thread depth in the Magnitude of 0.6 mm. It can - provided that the length the dispensing spout is 28 mm - 10 to 20 mm wide in the catheter shaft be incised. In any case, the internal thread length should not be the length of the Exceed dispensing spout because there is a smooth inner catheter wall beyond its mouth is to be preferred.
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 only, the Attachment of the shape deviation, especially the thread, not a big one Require effort. The thread is inserted into the polypropylene catheter tube with the help of a metal mandrel with threading combs, with a mandrel diameter of 5 mm and with a distance of 1 mm between the Comb, cut. The resulting chips are removed with the Unscrew the metal bolt again. The process is easy automate, which is advantageous for the implementation of the invention.
Außer durch ein Gewinde im Katheterschaft, können die abweichenden Formen auch durch andere Gestaltungen gebildet sein, beispielsweise durch Einzelvorsprünge, die eine kleinflächige Pressung auf Oberflächenteile der Abgabentülle ausüben und diese hierdurch verformen und festhalten; oder durch komplementäre Formgebungen wie Vertiefung und Vorsprung, die einerseits an der Innenwand des Katheterschafts und andererseits an der Außenseite der Abgabetülle ausgebildet sind und durch elastische Verformung zusammenschnappen; oder durch Widerhaken, die an der Abgabetülle sitzen.Except through a thread in the catheter shaft, the deviating ones Shapes can also be formed by other designs, for example by Single projections, which press a small area on surface parts of the Exercise the tax spout, thereby deforming and holding it; or through complementary shapes such as recess and projection, which on the one hand on the inner wall of the catheter shaft and on the other hand on the Are formed outside of the dispensing spout and by elastic deformation snap together; or by barbs that sit on the dispensing spout.
In der US 2 106 635 A ist zwar ein auch als Besamungskatheter verwendbarer Katheter beschrieben, der an seinem proximalen Ende außenseitig eine Riffelung zum Festhalten eines Gummischlauchs oder dergleichen, der zu einem Flüssigkeitsabgabepunkt führt, gebildet ist. Diese Riffelung an der Außenseite, die hauptsächlich für den Anschluß einer Einspeisung einer Spülflüssigkeit gedacht ist, gibt keine Anregung im Sinne der Stabilisierung des Halts einer in das Katheterrohr einzusteckenden Spermatube.US Pat. No. 2,106,635 A can also be used as an insemination catheter Described catheter, the one on its proximal end Grooving to hold a rubber hose or the like that leads to a Liquid discharge point leads, is formed. This corrugation on the outside, mainly for the connection of a feed of a rinsing liquid is thought to give no suggestion in the sense of stabilizing the hold of one in the sperm tube to be inserted.

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 one in Fig. 1 based on a sectional view

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 applied are brought up in a
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.2 shows, the inseminator breaks or cuts before the insemination process the tip of the spout with the widening 13 as if by scissors is symbolized.
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
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.The M6 thread standard has been chosen for the special pig insemination set proven to be very effective. However, it is not the only one Possible execution. Depending on the pipe diameter, on the Wall thickness and the materials, but also with the dimensioning described can also deviate thread dimensions, for example non-metric threads and other thread pitches, to a sufficient Lead fixation.
Möglichkeiten, die andere Mittel als Gewinde verwenden, sind in den Fig.n
4 bis 6 dargestellt. Gemäß Fig. 4 stehen von der Innenwand des Katheterschafts
2 Vorsprünge 19 vor, die gemäß der bevorzugten dargestellten Art und Weise
vier an Zahl sind, jedoch auch drei sein könnten oder ein einziger Ringvorsprung
sein könnte. Die Vorsprünge 19 sind so dimensioniert, daß sie beim
Einschieben der Abgabetülle 11 diese zusammendrücken, wobei das Tüllenmaterial
im Fall diskreter Vorsprünge in deren Zwischenräume verdrängt wird und
im Fall eines einzigen Ringvorsprungs sich in Falten legt. Die Rückstellfederkraft
der verformten Abgabetülle 11 sorgt für eine ausreichende Haftreibung,
um ein Herausfallen der Spermatube 9 zu verhindern.Possibilities that use other means than thread are in the Fig.n.
4 to 6 shown. 4 stand from the inner wall of the
Nach Fig. 5 weisen die beiden zu koppelnden Teile komplementäre
Formgebungen zum Zweck eines Zusammenschnappens auf. Im Katheterschaft
2 ist eine rinnenförmige Ringnut 21 gebildet, und an einer in der vollständigen
Einsteckstellung der Abgabetülle 11 gegenüberliegenden Stelle dieser Tülle ist
ein Ringwulst 22 gebildet oder sind in Abständen entlang einem Umfangskreis
sitzende Noppen gebildet. Diese Tüllenvorsprünge stehen ausreichend weit vor,
um trotz der konischen Ausbildung der Tülle im zusammengesteckten Zustand
in die Ringnut 21 vorzudringen. Beim Einschieben wird zunächst an der
Mündung des Katheterschafts 2 die Abgabetülle 11 etwas zusammengedrückt,
und damit hier keine Hemmung entsteht, ist der Ringwulst 22 zur Seite der
Tüllenspitze hin mit einem konisch-schrägen Übergangsbereich 23 ausreichenden
Durchmessers an der stumpfen Seite versehen.5, the two parts to be coupled have complementary parts
Shapes for the purpose of snapping together. In the
Fig. 6, schließlich, zeigt eine Fixierung der Abgabetülle 11 ohne besondere
Formgebung am Katheterschaft 2, nur durch beim dargestellten Beispiel vier
Widerhaken 25, die von der Außenfläche der Tülle 11 schräg nach hinten
abstehen und sich durch ihre Federkraft nach dem Einschieben in den Katheterschaft
2 an dessen Innenwand einhaken.6, finally, shows a fixation of the dispensing
