Abstract

The present invention relates to a device for inseminating animals, mainly sows. This device includes a catheter (1) for forwarding the sperm which is introduced in the vagina. The catheter comprises a bead (2.1, 2.2, 2.3, 2.4) in the area of the end to be introduced (1.1), as well as an essentially sleeve-shaped hollow body (6; 16) to be introduced at the start of the vagina and through which the bead and the catheter can be pushed into the vagina. In order to prevent sperm reflux in a simple manner, the bead (2.1, 2.2, 2.3, 2.4) is made of cellular foam or the like. Before being introduced into the organic cavity, the bead can be compressed on a cross section which is smaller than the lumen of the organic cavity. The bead further expands, after an expansion time as it reaches the end position corresponding to the uterus of the animal, until the animal's organic cavity is occluded by a soft retractable plug (20).

Description

Die Erfindung betrifft eine Vorrichtung zur Besamung von Tieren, insbesondere Sauen, gemäß dem Oberbegriff von Anspruch 1.The invention relates to a device for insemination of Animals, in particular sows, according to the preamble of claim 1.

Eine derartige Vorrichtung ist DE U1 295 05 177.9 des Anmelders zu entnehmen. Der Katheter, der im wesentlichen aus einem relativ steifen Kunststoffrohr besteht, geht an seinem Ende in einen Wulst über, der das Zurückfließen der Samenflüssigkeit bei der Besamung verhindern soll. Ferner ist gemäß vorgenanntem Stand der Technik ein Hohlkörper, vorzugsweise in Form einer Hülse, vorgesehen, der den Wulst und den Katheter umgibt und der bei Einführen des Katheters in die Vagina durchstoßen wird, so daß eine Verbesserung gegenüber infektiöser Kontamination gegeben ist, wie aus der Beschreibung des vorgenannten Standes der Technik hervorgeht.Such a device is DE U1 295 05 177.9 from the applicant refer to. The catheter, which essentially consists of one there is a relatively stiff plastic tube, goes to his End in a bulge that prevents the semen from flowing back should prevent insemination. Furthermore, according to a hollow body, preferably in the form of a sleeve, provided that the bead and the Surrounds the catheter and when the catheter is inserted into the Vagina is pierced, making an improvement over infectious contamination is given, as from the description of the aforementioned prior art.

Es hat sich gezeigt, daß ein mit einem bestimmten Durchmesser versehener Wulst zu Verletzungen der Vagina führen kann, da je nach Lebensalter der Tiere das Lumen der Vagina verschieden weit ist. It has been shown that one with a certain diameter provided bulge can lead to injuries to the vagina because Depending on the age of the animals, the lumen of the vagina varies is far.

Es ist auch schon der Vorschlag gemacht worden, einen Katheter nach Art der sogenannten Ballonkatheter mit einem aufblasbaren Wulst zu versehen, der nach Einführen mit Hilfe einer Luftpumpe oder dergleichen aufgeblasen wird (vgl. DE-AS 1766902). Diese Art eines veränderbaren Wulstes hat jedoch den Nachteil, daß die Handhabung im Tierstall und im Bereich der sich ungebärdig verhaltenden Tiere sehr schwierig ist, so daß eine Anwendung praktisch ausgeschlossen ist.The suggestion has already been made, a catheter in the manner of the so-called balloon catheter with an inflatable Bead to be provided after insertion with the aid of a Air pump or the like is inflated (see. DE-AS 1766902). However, this type of changeable bead has the disadvantage that handling in the animal stable and in the area which is very difficult to behave unruly, so that an application is practically impossible.

Es stellt sich daher die Aufgabe, eine Besamungsvorrichtung anzugeben, die einerseits die Vorteile des Gebrauchsmusters 295 05 177 besitzt, andererseits das Zurückfließen der Samenflüssigkeit weitgehend verhindert, ohne daß eine komplizierte Handhabung erforderlich ist.It is therefore the task of a insemination device specify the one hand the advantages of the utility model 295 05 177 has, on the other hand, the backflow of semen largely prevented without a complicated Handling is required.

Diese Aufgabe wird erfindungsgemäß durch eine Vorrichtung gemäß Anspruch 1 gelöst.This object is achieved by a device solved according to claim 1.

Vorzugsweise ist der Wulst torus- oder zylindrischhülsenförmig ausgebildet und am einzuführenden Ende des Katheters angebracht. Eine zusätzliche Luftführung ist nicht erforderlich. Eine entsprechende Kunststoff-Schaummasse kann so eingestellt werden, daß nach dem Zusammendrücken, was beispielsweise manuell oder aber durch die Außenwandung des Hohlkörpers geschehen kann, eine ausreichende Zeit verbleibt, bis sich der Wulst wieder soweit gedehnt hat, daß er die Innenwandung der Vagina abschließt. Das verwendete Material - Schaumkunststoff - ist so weich, daß es leicht wieder aus der Vagina zurückgezogen werden kann, ohne daß es zu Verletzungen kommt.The bead is preferably toroidal or cylindrical sleeve-shaped trained and at the end of the catheter to be inserted appropriate. An additional air flow is not required. A suitable plastic foam mass can can be set so that after compressing what, for example manually or through the outer wall of the Hollow body can happen, sufficient time remains until the bead has stretched again so far that it has the inner wall which closes the vagina. The material used - Foam plastic - is so soft that it easily comes out of the Vagina can be withdrawn without causing injury comes.

Um den Wulst genau zu plazieren und unverrückbar zu machen, wird vorgeschlagen, daß das Ende des Katheters eine nach außen gerichtete Verdickung aufweist, an der sich der Wulst abstützt. Vorzugsweise kann auch eine zweite Verdickung vorgesehen sein, die in einem, etwa einer Wulstlänge entsprechenden Abstand von der ersten Verdickung angeordnet ist. Die Außendurchmesser der Verdickung sind so bemessen, daß sie das Lumen der Vagina unterschreiten und damit nicht zu Verletzungen führen können.To place the bead precisely and make it immovable, it is suggested that the end of the catheter be an outward has directed thickening on which the bead is supported. A second thickening can preferably also be provided be in a, approximately corresponding to a bead length Distance from the first thickening is arranged. The outside diameter the thickening are such that they are Fall below the lumen of the vagina and therefore not cause injuries being able to lead.

Für das Material des Wulstes eignen sich weichelastische Schaumkunststoffe, die zusammendrückbar sind und sich nach dem Loslassen in einer bestimmten Zeit, beispielsweise innerhalb von 10 bis 30 Sekunden erweitern und wieder dehnen und die ursprüngliche Form wieder annehmen. Beispielsweise haben Schaumkunststoffe aus Polyurethan diese Eigenschaft. Es werden hierzu Weichschaumstoffe gemäß DIN 7726 verwendet, die bei Druckbelastung einen relativ geringen Verformungswiderstand aufweisen. Das langsame Retardieren kann mit Hilfe von Weichmachern und dem Fachmann bekannten Rezepturen eingestellt werden.Soft elastic are suitable for the material of the bead Foam plastics that are compressible and that releasing in a certain time, for example within expand from 10 to 30 seconds and stretch again and return to the original form. For example Foam plastics made of polyurethane have this property. It will soft foams according to DIN 7726 are used for this a relatively low resistance to deformation when subjected to pressure exhibit. Slow retardation can be done with the help of Plasticizers and recipes known to those skilled in the art become.

Das Zusammendrücken und Aufrechterhalten des komprimierten Wulstes vor der eigentlichen Besamung kann in unterschiedlicher Weise erreicht werden. Beispielsweise kann eine abreißbare Folienhülse verwendet werden. Der freigegebene Wulst erweitert sich zu seiner ursprünglichen Form, wobei innerhalb einer bestimmten Zeit, die ausreicht, daß die Katheterspitze den Muttermund erreicht, die Form wieder angenommen wird.Squeezing and maintaining the compressed Bead before the actual insemination can be in different Way to be achieved. For example, a tearable Foil sleeve can be used. The released bead expands to its original form, being inside a certain time that is sufficient for the catheter tip reached the cervix, the shape is restored.

Der Wulst kann entsprechend den Bedürfnissen und unter Berücksichtigung von Herstellungskosten an seiner Außenseite glatt-zylindrisch sein; es ist aber auch möglich, ihn in Form einer Spirale oder mit lamellenartigen Unterbrechungen zu versehen, so daß er an seiner Außenseite einer ring- oder spiralförmige, periphere Ausnehmung aufweist.The bead can be made according to needs and taking into account of manufacturing costs on its outside be smooth-cylindrical; but it is also possible to shape it a spiral or with lamellar interruptions provided so that it is a ring or Has spiral, peripheral recess.

Um das Zurückfließen der Samenflüssigkeit zu verhindern, ist am Katheter eine Knickstelle oder ein Rücklaufventil vorgesehen, das an seinem dem Wulst gegenüberliegenden Ende angeordnet ist.To prevent the semen from flowing back a kink or a return valve is provided on the catheter, arranged at its end opposite the bead is.

Darauf hinzuweisen ist, daß der vor Beginn der Besamung den Wulst umgebende, vor infektiöser Kontamination schützender Hohlkörper nach der Einführung am Beginn der Vagina verbleibt, während das mit dem Wulst versehene Ende des Katheters in Richtung Gebärmutter verschiebbar ist und aus dem Hohlkörper ausschiebbar ist.It should be noted that before the insemination the Bead surrounding, protecting against infectious contamination Hollow body remains at the beginning of the vagina after insertion, during the beaded end of the catheter is displaceable towards the uterus and out of the Hollow body can be pushed out.

Der Hohlkörper kann "zweistufig" ausgebildet, d.h. in zwei Kammern unterteilt sein, von denen eine erste Kammer zur Aufnahme des nicht komprimierten Wulstes dient. Bei Lagerung wird der erweiterte Wulst nicht zusammengedrückt und vor Beschädigungen geschützt. Die kleinere, zweite Kammer dient wiederum zur Aufnahme des zusammengedrückten Wulstes.The hollow body can be "two-stage", i.e. in two Be divided into chambers, of which a first chamber for receiving of the non-compressed bead. When storing the expanded bead is not pressed together and is damaged protected. The smaller, second chamber serves again to take up the compressed bead.

In Figur 1 ist eine Vorrichtung 100 zur künstlichen Besamung von Sauen dargestellt, die sich aus einem Katheter 1 und einem an ein Rohrende 1.1 des Katheters eingesetzten, hülsenförmigen Wulst 2.1 zusammensetzt.1 shows a device 100 for artificial insemination shown by sows, which consist of a catheter 1 and a inserted into a tube end 1.1 of the catheter, sleeve-shaped Bead 2.1 composed.

Das Ende 1.1 des Katheters weist eine nach außen gerichtete, kegelförmige Verdickung 4.1 auf, an der sich der an dem Katheter aufgesetzte Wulst 2.1 abstützt. Am Katheter 1 ist noch eine zweite Verdickung 4.2 angebracht, die in einem etwa einer Wulstlänge L entsprechenden Abstand A von der ersten Verdickung 4.1 angeordnet ist. Damit ist die axiale Lage des Wulstes 2.1 gegenüber dem Katheter durch die Anordnung der beiden Verdickungen 4.1, 4.2 festgelegt. In gleicher Weise sind am Katheter 1 die Wülste 2.2, 2.3 und 2.4 (vgl. Figuren 2 bis 4) aufgesetzt. Angesicht der hohen Anforderungen an Sterilität ist der Katheter 1 mit Wulst 2.1, 2.2, 2.3,2.4 als Einweg-Vorrichtung konzipiert. Die Wülste 2.1, 2.2, 2.3, 2.4 können auch als auswechselbare Einweg-Elemente verwendet werden.The end 1.1 of the catheter has an outwardly directed conical thickening 4.1 on which the catheter attached bead 2.1 supports. At catheter 1 is still a second thickening 4.2 attached, in a roughly one Bead length L corresponding distance A from the first thickening 4.1 is arranged. So that the axial position of the Bead 2.1 against the catheter by the arrangement of the two thickenings 4.1, 4.2 set. In the same way are the beads 2.2, 2.3 and 2.4 on the catheter 1 (cf. figures 2 to 4). Given the high demands on Sterility is the catheter 1 with bead 2.1, 2.2, 2.3.2.4 as Disposable device designed. The ridges 2.1, 2.2, 2.3, 2.4 can also be used as interchangeable single-use elements.

In Figur 2 ist eine ähnliche (Bezugszahl 200) Vorrichtung dargestellt, bei der der auswechselbare Wulst 2.2 mehrere peripheren Ausnehmungen 3.1 aufweist. Wie das obere Teil der Figur zeigt, nimmt der vorher komprimierte Wulst 2.2 ein wesentlich vergrößertes Volumen an und verwandelt sich in einen Pfropfen 20, der auch in Figur 6 zu sehen ist.In Figure 2 is a similar (reference number 200) device shown, in which the replaceable bead 2.2 several peripheral Has recesses 3.1. Like the top of the Figure shows, the previously compressed bead 2.2 takes a significant increased volume and turns into one Plug 20, which can also be seen in Figure 6.

Ferner sind in den Figuren 3 und 4 andere Ausführungsformen (Bezugszahlen 2.3, 2.4) des Wulstes gezeigt, bei denen der erweiterte Wulst (Pfropfen) Abrundungen 9 oder Abschrägungen 11 aufweist, damit die Katheterspitze leichter geführt werden kann und das Tier nicht verletzt wird.Furthermore, other embodiments are shown in FIGS. 3 and 4 (Reference numbers 2.3, 2.4) of the bead shown, in which the extended bead (grafting) rounding 9 or bevels 11 so that the catheter tip can be guided more easily can and the animal is not injured.

Der in Fig.3 gezeigte Wulst besitzt eine einzige, spiralförmige Ausnehmung 3.2. Der Wulst 2.1, 2.2, 2.3, 2.4 ist aus einem weichen, geschlossenzelligen Polyethylen oder Polyurethan einer Dichte etwa von 40 kg/m3 angefertigt, wobei mit Hilfe von Weichmachern und anderen Additiven die Rückstellzeit des Schaumstoffes so eingestellt ist, daß der Pfropfen so zusammendrückbar ist, daß der Querschnitt das Lumen der Vagina unterschreitet. Zunächst wird der Muttermund des Tieres erreicht. Innerhalb der Endposition wird das Ende der Expansionszeit abgewartet, wobei der Pfropfen sich soweit ausdehnt, daß die Vagina mit einem weichen, zurückziehbaren Pfropfen 20 verschlossen ist. Die Einstellung der Expansionzeit entsprechend der Temperatur der Vagina und der Größe, kann nach fachmännischem Ermessen mit entsprechenden Schaumstoffkörpern erfolgen. The bead shown in Figure 3 has a single, spiral recess 3.2. The bead 2.1, 2.2, 2.3, 2.4 is made of a soft, closed-cell polyethylene or polyurethane with a density of about 40 kg / m 3 , with the aid of plasticizers and other additives the return time of the foam being set so that the plug can be compressed is that the cross section falls below the lumen of the vagina. First, the animal's cervix is reached. Within the end position, the end of the expansion time is awaited, the plug expanding so far that the vagina is closed with a soft, retractable plug 20. The expansion time can be set according to the temperature of the vagina and the size, according to professional judgment with appropriate foam bodies.

Bei einer anderen Ausführungsform (Bezugszahl 300; vgl.Fig. 5a) ist der Hohlkörper 16 in zwei Kammern aufgeteilt, nämlich in eine erste, größere Kammer 25 zur Aufnahme des nicht komprimierten Wulstes und eine zweite, kleinere Kammer zur Aufnahme des zusammengedrückten Wulstes. Die Lage des nicht komprimierten Wulstes in der ersten Kammer 25 ist durch die Noppen 33 definiert, die an der inneren Oberfläche des zylindrischen Teils (Kammer 25) angeordnet sind und die in die peripheren Ausnehmungen 3.1 des Wulstes hineinpassen.In another embodiment (reference number 300; see Fig. 5a), the hollow body 16 is divided into two chambers, namely in a first, larger chamber 25 for receiving the uncompressed Bead and a second, smaller chamber for receiving of the compressed bead. The location of the uncompressed Bead in the first chamber 25 is through the knobs 33 defines that on the inner surface of the cylindrical Part (chamber 25) are arranged and in the peripheral Fit recesses 3.1 of the bead.

Wie die Figur zeigt, ist der Hohlkörper 16 in einem Übergangsbereich 27 von der ersten in die zweite Kammer sanft verjüngt. Im Ubergangsbereich 27 ist auch eine am Mantel des Hohlkörpers 16 eingearbeitete Öffnung 32 zu sehen, durch die ein flüssiges Gleitmittel in das Innere des Hohlkörpers mittels einer nicht dargestellten Pipette einzuführen ist.As the figure shows, the hollow body 16 is in a transition region 27 gently from the first to the second chamber rejuvenated. In the transition area 27 there is also one on the jacket of the Hollow body 16 incorporated opening 32 through which a liquid lubricant into the interior of the hollow body a pipette, not shown, is to be introduced.

Weiterhin ist bei der Vorrichtung 300 eine aus Kunststoff hergestellte Ringscheibe 28, 28.1 vorgesehen, die sich entweder an das verjüngte Teil (Übergangsbereich 27) des Hohlkörpers 16 oder an dessen Kragen 34 stützt. Die als Anschlagelement bei der Besamung dienende, entsprechend desinfizierte Ringscheibe 28, 28.1 kann mehrfach verwendet werden.Furthermore, the device 300 is made of plastic manufactured washer 28, 28.1 provided that either to the tapered part (transition region 27) of the hollow body 16 or on the collar 34 supports. The as a stop element for the insemination, appropriately disinfected Washer 28, 28.1 can be used several times.

Ist der günstigste Zeitpunkt für die Belegung festgelegt, wird die künstliche Besamung wie folgt durchgeführt:Once the best time for occupancy has been determined, the artificial insemination is carried out as follows:

Zuerst ist die Scham 21 (vgl. Fig. 6) sehr intensiv zu reinigen. Danach wird der Wulst und das Äußere des Hohlkörpers mit Parafinöl behandelt und gleitfähig gemacht. Andere Gleitmittel sind nicht zu verwenden, da sie das Sperma schädigen können.First of all, the pubic area 21 (see FIG. 6) must be cleaned very intensively. Then the bead and the exterior of the hollow body with Paraffin oil treated and made lubricious. Other lubricants are not to be used as they can damage the sperm.

Danach wird die Vorrichtung, wie sie die Fig. 1 zeigt, mit dem Hohlkörper 6 voran in die Scheide 31 eingeführt. Der Hohlkörper 6 ist so weit in die Scheide 31 einführbar, bis sein nach außen ragender Kragen 6.1 bzw. Ringscheibe 28, 28.1 (vgl. Fig. 5a) auf der äußeren Scham aufliegt. Beim Weiterschieben der Vorrichtung stößt die Verdickung 4.1 gegen einen Kegelstumpf 6.2 des Hohlkörpers 6 und öffnet seine Dünnfilmverschlüsse 6.3 und läßt den Wulst passieren. Dieser wird nun keimarm bis hin zum Muttermund geführt. Der zunächst komprimierte Wulst erweitert sich innerhalb etwa 20 Sekunden, nimmt sein größtes Volumen an und verschließt die Vagina in Richtung Muttermund, so daß das Sperma zurück nicht fließen kann.Then the device, as shown in FIG. 1, with the hollow body 6 inserted into the vagina 31. The Hollow body 6 can be inserted into vagina 31 until its outwardly projecting collar 6.1 or annular disk 28, 28.1 (see Fig. 5a) rests on the outer pubic area. When moving on the device bumps the thickening 4.1 against one Truncated cone 6.2 of the hollow body 6 and opens its thin-film closures 6.3 and let the bead pass. This will now germ-free down to the cervix. The first compressed Bead expands within about 20 seconds, takes its largest volume and closes the vagina in the direction Cervix so that the sperm cannot flow back.

Um das Zurückfließen des Sperma durch den Katheter 1 zu verhindern, ist es vorgesehen, an seinem dem Wulst gegenüberliegenden Ende 1.2 eine Knickstelle 12 einzubringen. Durch das einfache Knicken des Katheters 1 und Einklemmen mit einer Klammer, Clipverschluß oder dgl. wird erreicht, daß dieser unmittelbar nach der Besamung verschlossen bleibt.To prevent the sperm from flowing back through the catheter 1, it is provided at its opposite the bead End 1.2 to introduce a kink 12. By the simple kinking of the catheter 1 and clamping with a Clamp, clip closure or the like. Is achieved that this remains closed immediately after insemination.

Bei einer anderen Ausführungsform weist der Katheter 1 ein an seinem dem Wulst gegenüberliegenden Ende 1.2 aufgesetztes Rücklaufventil 13 auf. Das Rücklaufventil 13 ist in der Form einer länglichen, elastischen Hülse 13.1 ausgeführt, die ein dünnhäutiges, membranartiges, ebenso elastisches Sperrorgan 23 besitzt. Beim Einführen eines angespitzten Spenderelementes 24 wird das Sperrorgan 23 durchstoßen. Beim Herausziehen des Spenderelementes 24 verschließt das elastische Sperrorgan 23 und verhindert das Zurückfließen der Samenflüssigkeit. Das Rücklaufventil 13 kann natürlich bei allen beschriebenen Ausführungsformen der Vorrichtung Verwendung finden.In another embodiment, the catheter 1 instructs one its end opposite the bead 1.2 Return valve 13 on. The return valve 13 is in the form an elongated, elastic sleeve 13.1 executed a thin-skinned, membrane-like, also elastic locking element 23 owns. When inserting a sharpened donor element 24 the locking member 23 is pierced. When pulling out the donor element 24 closes the elastic locking member 23 and prevents the sperm from flowing back. The Return valve 13 can of course in all described embodiments find use of the device.

Die Sau muß die Vorrichtung dabei "halten", d. h., beim Zurückziehen des Wulstes muß ein leichter Widerstand festzustellen sein. Der erfahrene Halter weiß dabei, bis zu welchem Punkt die Kathetereinheit zu führen hat. Danach wird an das Ende ein Samenbehälter 18 (vgl. Fig. 6) angeschlossen. Durch leichten Druck auf den Behälter 18 wird dafür gesorgt, daß das Sperma in die Gebärmutter 41 fließen kann. Die gesamte Zeit der Besamungsdauer sollte mindestens 3 Minuten dauern. Die Sau wird während und nach der Besamung entsprechend stimuliert.The sow must "hold" the device, i.e. i.e. when withdrawing there must be slight resistance to the bead his. The experienced keeper knows up to which Point to guide the catheter unit. After that, the End of a seed container 18 (see. Fig. 6) connected. By slight pressure on the container 18 is ensured that the sperm can flow into the uterus 41. The whole The duration of the insemination should last at least 3 minutes. The sow is stimulated accordingly during and after insemination.

Nach der Leerung des Samenbehälters 18 ist die Katheterspitze nicht sofort zurückzuziehen. So wird unnötiger Spermarückfluß vermieden. Ist eine gewisse Zeit abgelaufen, werden der Katheter 1 mit dem Wulst und zugleich der Hohlkörper 6 mit entfernt.After emptying the semen container 18 is the catheter tip not withdraw immediately. This will make unnecessary sperm reflux avoided. If a certain amount of time has expired, the catheter 1 with the bead and at the same time the hollow body 6 with removed.
