Abstract
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
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
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.

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

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,
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 (
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
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
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
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
