Description

Domaine technique de l'inventionTechnical field of the invention

La présente invention concerne la collecte de semence animale. Elle a pour objet un nouveau vagin artificiel qui permet la collecte manuelle de la semence animale.The present invention relates to the collection of animal semen. It is about a new artificial vagina that allows manual collection of animal semen.

Art antérieurPrior art

Pour prélever la semence d'un animal, tel que par exemple un verrat, bovin, équidé, lapin, etc..., il est à ce jour usuel d'utiliser des vagins artificiels permettant de stimuler la verge de l'animal et de provoquer son éjaculation.To collect the semen of an animal, such as for example a boar, bovine, equine, rabbit, etc ..., it is customary today to use artificial vaginas to stimulate the rod of the animal and cause ejaculation.

Il existe à ce jour de nombreuses variantes de vagins artificiels dont les structures sont plus ou moins complexes, et qui sont généralement adaptées à l'espèce animale dont on souhaite prélever la semence.To date, there are many variants of artificial vaginas whose structures are more or less complex and which are generally adapted to the animal species from which the seed is to be taken.

Par exemple, dans la demande de brevet européen EP 0 699 422 , il est proposé un vagin artificiel à usage unique de structure très simple, constitué d'un manchon tubulaire en mousse non toxique de polyuréthane, de polyéthylène ou de silicone. Ce vagin artificiel de structure très simple permet une collecte manuelle de la semence animale, la verge de l'animal devant nécessairement être stimulée manuellement par l'opérateur au moyen d'une pression exercée à l'aide du manchon tubulaire en mousse.For example, in the European patent application EP 0 699 422 it is proposed a disposable artificial vagina of very simple structure, consisting of a tubular sleeve of non-toxic foam of polyurethane, polyethylene or silicone. This artificial vagina of very simple structure allows manual collection of animal semen, the penis of the animal must necessarily be manually stimulated by the operator by means of pressure exerted by means of the tubular foam sleeve.

Ce type de vagin artificiel est avantageux car il présente une structure très simple. En revanche, il présente au moins l'inconvénient suivant. La mise en place du vagin artificiel sur la verge de l'animal est effectuée en enfilant le vagin sur la verge nécessairement selon l'axe longitudinal du vagin, ce qui s'avère d'autant peu pratique que le conduit de réception du vagin est dimensionné pour une taille unique de verge et en sorte d'obtenir un serrage modéré sur la verge.This type of artificial vagina is advantageous because it has a very simple structure. On the other hand, it presents at least the following disadvantage. The introduction of the artificial vagina on the penis of the animal is performed by putting the vagina on the penis necessarily along the longitudinal axis of the vagina, which proves all the more practical that the receiving duct of the vagina is dimensioned for a single size of penis and to obtain a moderate tightening on the penis.

On connaît également des vagins artificiels plus sophistiqués permettant une stimulation automatisée de la verge, notamment au moyen d'une chambre à pression variable alimentée par un fluide tel que de l'eau ou de l'air. Par exemple, la demande de brevet internationale WO 02/13723 divulgue un vagin artificiel mettant en oeuvre une chambre d'air étanche et permettant une stimulation localisée de la verge de l'animal au moyen de pulsations. Le brevet français FR 946 822 décrit une autre variante de réalisation connue d'un vagin artificiel pour la collecte automatisée de semence animale mettant en oeuvre une chambre de pression remplie d'eau ou d'air.There are also more sophisticated artificial vaginas allowing automated stimulation of the penis, in particular by means of a variable pressure chamber fed by a fluid such as water or air. For example, the international patent application WO 02/13723 discloses an artificial vagina using a sealed air chamber and allowing localized stimulation of the penis of the animal by means of pulsations. French patent FR 946 822 discloses another known embodiment of an artificial vagina for automated collection of animal semen using a pressure chamber filled with water or air.

Ces vagins artificiels à stimulation automatique sont intéressants car ils facilitent l'opération de collecte pour l'opérateur. En revanche, ils sont plus onéreux à fabriquer comparativement au vagin artificiel de la demande de brevet européen précitée EP 0 699 422 .These artificial vaginas with automatic stimulation are interesting because they facilitate the collection operation for the operator. On the other hand, they are more expensive to manufacture compared to the artificial vagina of the aforementioned European patent application. EP 0 699 422 .

Objectif de l'inventionObjective of the invention

La présente invention a pour objectif principal de proposer un nouveau vagin artificiel pour la collecte de semence animale, qui présente une structure simple permettant sa fabrication et sa mise en oeuvre à un faible coût tout en facilitant pour l'opérateur les opérations de collecte.The main object of the present invention is to propose a new artificial vagina for the collection of animal semen, which has a simple structure allowing its manufacture and its implementation at a low cost while facilitating for the operator the collection operations.

Description détailléedetailed description

On a représenté sur les figures 1 et 5 une variante de réalisation d'un vagin artificiel 1 qui est conforme à l'invention, et qui est plus particulièrement destiné à la collecte de la semence porcine.We have shown on figures 1 and 5 an alternative embodiment of an artificial vagina 1 which is in accordance with the invention, and which is more particularly intended for the collection of porcine semen.

Ce vagin artificiel 1 comporte deux demi-coques 3a, 3b rigides et articulées en rotation l'une par rapport à l'autre au moyen d'une charnière longitudinale 31. Ces deux demi-coques 3a, 3b articulées sont par exemple en matière plastique. A l'intérieur de chaque demi-coque 3a, 3b est fixé un demi-manchon 2a, 2b mou et déformable élastiquement. Les deux demi-manchons 2a et 2b comprennent chacun une paroi interne 22a, 22b, et une paroi externe 23a, 23b. Sur la figure 1, les deux demi-coques 3a, 3b et leur demi-manchons 2a, 2b sont en position dite ouverte. Sur la figure 5, les deux demi-coques 3a, 3b et leur demi-manchons 2a, 2b sont en position dite fermée.This artificial vagina 1 comprises two half-shells 3a, 3b rigid and articulated in rotation relative to each other by means of a longitudinal hinge 31. These two half-shells 3a, 3b articulated are for example plastic . Inside each half-shell 3a, 3b is fixed a half-sleeve 2a, 2b soft and elastically deformable. The two half-sleeves 2a and 2b each comprise an inner wall 22a, 22b, and an outer wall 23a, 23b. On the figure 1 , the two half-shells 3a, 3b and their half-sleeves 2a, 2b are in said open position. On the figure 5 , the two half-shells 3a, 3b and their half-sleeves 2a, 2b are in said closed position.

La charnière longitudinale 31 permet au vagin artificiel 1 de passer de la position ouverte qui est représentée aux figures 1 à 4, et dans laquelle le vagin artificiel 1 est apte à être positionné sur la verge d'un animal, à une position dite « fermée », qui est représentée à la figure 5 , et dans laquelle le vagin artificiel 1 est configuré pour la mise en érection de la verge de l'animal.The longitudinal hinge 31 allows the artificial vagina 1 to move from the open position which is shown in FIGS. Figures 1 to 4 , and in which the artificial vagina 1 is adapted to be positioned on the rod of an animal, in a so-called "closed" position, which is shown in FIG. figure 5 , and wherein the artificial vagina 1 is configured for erection of the penis of the animal.

En référence à la figure 5, lorsque les deux demi-coques 3a, 3b sont refermées l'une sur l'autre, elle forme une coque 3 tubulaire, rigide et ouverte à ses deux extrémités. Lorsque les deux-demis coques 3a, 3b sont dans cette position fermée, les deux demi-manchons 2a, 2b délimitent un logement interne 21 d'axe longitudinal A, qui est sensiblement cylindrique ou conique, et qui est apte à recevoir la verge d'un animal dont on souhaite prélever la semence.With reference to the figure 5 when the two half-shells 3a, 3b are closed one on the other, it forms a tubular shell 3 rigid and open at both ends. When the two half-shells 3a, 3b are in this closed position, the two half-sleeves 2a, 2b delimit an inner housing 21 of longitudinal axis A, which is substantially cylindrical or conical, and which is adapted to receive the penis of an animal from which one wishes to take the seed.

Les demi-manchons 2a, 2b sont réalisés dans un matériau mou et déformable élastiquement. Il s'agit de préférence d'un élastomère ou d'une mousse. De manière avantageuse, le logement 21 permet de ne pas blesser l'animal lors de la mise en place du vagin artificiel 1 et pendant la récolte de la semence, tout en lui garantissant un excellent confort.The half-sleeves 2a, 2b are made of a soft material and elastically deformable. It is preferably an elastomer or a foam. Advantageously, the housing 21 allows not to injure the animal during the introduction of the artificial vagina 1 and during the harvest of the seed, while ensuring excellent comfort.

La structure en deux demi-coques articulées permet de positionner facilement la verge de l'animal dans le logement 21 du vagin artificiel.The structure in two articulated half-shells makes it easy to position the penis of the animal in the housing 21 of the artificial vagina.

Dans la variante particulière de réalisation illustrée sur la figure 4, chaque demi-coque 3a, 3b comporte une ouverture 30a, 30b, qui dans l'exemple illustré forme une fenêtre rectangulaire. Ces ouvertures 30a, 30b débouchent respectivement sur les deux demi-manchons 2a, 2b. Lorsque les deux-demis coques 3a, 3b sont dans la position fermée de la figure 5, les deux ouvertures latérales 30a, 30b sont diamétralement opposées et permettent d'exercer manuellement à travers la coque une pression radiale par pincement sur les deux demi- manchons 2a, 2b.In the particular embodiment illustrated on the figure 4 each half-shell 3a, 3b has an opening 30a, 30b, which in the illustrated example forms a rectangular window. These openings 30a, 30b open respectively to the two half-sleeves 2a, 2b. When the two half-hulls 3a, 3b are in the closed position of the figure 5 , the two lateral openings 30a, 30b are diametrically opposed and allow to exert manually through the shell a radial pressure by pinching on the two half-sleeves 2a, 2b.

Comme représenté à la figure 1, les parois internes 22a, 22b des deux demi-manchons 2a, 2b sont formées de telle sorte que le logement 21 formé par ces deux demi-manchons 2a, 2b présente une forme hélicoïdale qui est adaptée par exemple à la verge d'un verrat. L'invention n'est toutefois pas limitée à un logement 21 de forme hélicoïdale, les parois internes 22a ,22b du logement 21 pouvant avoir d'autres formes.As represented in figure 1 , the inner walls 22a, 22b of the two half-sleeves 2a, 2b are formed such that the housing 21 formed by these two half-sleeves 2a, 2b has a helical shape which is adapted for example to the verge of a boar . The invention is however not limited to a housing 21 of helical shape, the inner walls 22a, 22b of the housing 21 may have other shapes.

Pour maintenir de manière sûre le vagin artificiel 1 en position fermée lorsque la verge d'un animal est présente à l'intérieur dudit vagin 1, les demi-coques 3a, 3b sont pourvues de moyens de verrouillage 32a, 32b permettant de verrouiller ensemble les deux demi-coques 3a, 3b en position fermée.To securely maintain the artificial vagina 1 in the closed position when the penis of an animal is present inside said vagina 1, the half-shells 3a, 3b are provided with locking means 32a, 32b for locking together the two half-shells 3a, 3b in the closed position.

Plus précisément, les moyens de verrouillage comprennent deux ergots 32a sur la demi-coque 3a qui sont aptes à coopérer par emboîtement avec une nervure 32b de l'autre demi-coque 3b, afin de maintenir les deux demi-coques 3a, 3b sensiblement jointes.More specifically, the locking means comprise two lugs 32a on the half-shell 3a which are adapted to cooperate by interlocking with a rib 32b of the other half-shell 3b, to maintain the two half-shells 3a, 3b substantially joined.

Les moyens de verrouillage 32a, 32b ont été décrits à titre d'exemple non limitatifs de l'invention, tout autre moyen mécanique permettant de maintenir les deux demis-coques 3a, 3b fermées pouvant être utilisé. Par exemple on pourrait utiliser des sangles pour maintenir les demi-coques 3a, 3b en position fermée.The locking means 32a, 32b have been described by way of non-limiting example of the invention, any other mechanical means for maintaining the two half-shells 3a, 3b closed can be used. For example one could use straps to maintain the half-shells 3a, 3b in the closed position.

Sur la figure 1, on a référencé 10a l'extrémité proximale du vagin artificiel qui est destinée à être enfilée la première sur la verge de l'animal et on a référencé 10b, l'autre extrémité, dite distale, du vagin artificiel par laquelle peut s'écouler la semence de l'animal lors de l'opération de récolte.On the figure 1 10a is referred to the proximal end of the artificial vagina which is intended to be threaded first on the penis of the animal and 10b is referenced, the other end, called distal, the artificial vagina through which can flow the seed of the animal during the harvest operation.

En référence à la figure 1 et 5, les deux demi-coques 3a, 3b comportent deux demi-collerettes complémentaires 33a, 33b au niveau de leur extrémité distale 10b. Lorsque les deux demi-coques 3a, 3b sont en position fermée, les deux demi-collerettes 33a, 33b sont jointives et forment un support rigide permettant la fixation d'un moyen de récolte de la semence de l'animal, tel que par exemple un dispositif de collecte 5 représenté sur la figure 7.With reference to the figure 1 and 5 , the two half-shells 3a, 3b comprise two complementary half-flanges 33a, 33b at their distal end 10b. When the two half-shells 3a, 3b are in the closed position, the two half-collars 33a, 33b are joined and form a rigid support for the attachment of a means for harvesting the animal's semen, such as, for example a collection device 5 shown on the figure 7 .

Dans la variante particulière de réalisation des figures 1 et 5, afin d'assurer un positionnement correcte des deux demi-coques l'une par rapport à l'autre en position fermée, la demi-coque 3a comporte une partie mâle 36a qui est apte venir s'emboiter temporairement dans une partie femelle 36b (formant une lumière de guidage) de l'autre demi-coque 3b, lors du rapprochement des deux demi-coques 3a, 3b. Le guidage de la partie male 36a par la partie femelle 36b permet d'assurer un alignement correct des deux demi-coques 3a, 3b en position fermée.In the particular variant embodiment of figures 1 and 5 , in order to ensure correct positioning of the two half-shells with respect to each other in the closed position, the half-shell 3a comprises a male part 36a which is able to fit temporarily into a female part 36b ( forming a guiding light) of the other half-shell 3b, when bringing together the two half-shells 3a, 3b. Guiding the male portion 36a by the female portion 36b ensures proper alignment of the two half-shells 3a, 3b in the closed position.

En référence à cette figure 7, le dispositif de collecte 5 qui est représenté à titre d'exemple non limitatif de l'invention, comporte une bague de montage rigide 50 et un sachet de collecte 51 solidaire de la bague de montage 50. A l'intérieur du sachet de collecte 51 est prévu un cône filtrant 52, réalisé au moyen d'un non-tissé 52a fixé sur une armature 52b en U. La bague de montage 50 comporte deux ergots 53a, 53b qui sont diamétralement opposés, et qui sont aptes à être insérés respectivement dans deux logements 34a, 34b (figure 3) ménagés les deux demi-collerettes 33a, 33b, lorsque les deux demi-coques 3a,3b sont en position fermée . Ces ergots 53a et 53b forment, avec les deux logements 34a, 34b, un système de fixation de type baïonnette.With reference to this figure 7 , the collection device 5 which is shown by way of non-limiting example of the invention, comprises a rigid mounting ring 50 and a collection bag 51 integral with the mounting ring 50. Inside the collection bag 51 is provided a filter cone 52, made by means of a nonwoven 52a fixed on a frame 52b U. The mounting ring 50 has two lugs 53a, 53b which are diametrically opposed, and which are adapted to be inserted respectively into two housings 34a, 34b ( figure 3 ) provided the two half-flanges 33a, 33b, when the two half-shells 3a, 3b are in the closed position. These lugs 53a and 53b form, with the two housing 34a, 34b, a bayonet type fixing system.

La semence animale comporte plusieurs fractions différentes : une première fraction est constituée par un liquide contenant les spermatozoïdes et également certaines bactéries, et formant le liquide séminal ; une deuxième fraction est constituée par une substance formant une sorte de gel et encore désignée « tapioca ». Les moyens de filtration 52 du dispositif de collecte 5 de la figure 7 permettent avantageusement de retenir la deuxième fraction, et de laisser passer dans le fond du sachet 51 uniquement le liquide séminal qui constitue la fraction utile pour l'insémination artificielle postérieure à l'étape de prélèvement.The animal semen has several different fractions: a first fraction is constituted by a liquid containing the spermatozoa and also some bacteria, and forming the seminal fluid; a second fraction is constituted by a substance forming a kind of gel and still referred to as "tapioca". The filtration means 52 of the collection device 5 of the figure 7 advantageously allow to retain the second fraction, and let pass in the bottom of the bag 51 only the seminal fluid which is the fraction useful for artificial insemination posterior to the sampling step.

Les demi-manchons 2a, 2b mous et déformables permettent d'éviter que la face interne des demi-coques 3a, 3b ne soit en contact direct avec la verge de l'animal. Egalement, selon une caractéristique facultative de l'invention, à l'extrémité proximale 10a du vagin artificiel 1, les deux demi-manchons 2a, 2b font avantageusement saillie hors des demi-coques 3a,3b et comportent deux demi-collerettes 20a, 20b qui recouvrent le bord proximal 35a, 35b des demi-coques 3a,3b (figures 1 et 3), de manière à ce que le bord proximal des demi-coques 3a,3b ne puisse entrer en contact avec l'animal. On évite ainsi les risques de blessure de l'animal avec les demi-coques 3a, 3b.The soft and deformable half-sleeves 2a, 2b make it possible to prevent the inner face of the half-shells 3a, 3b from being in direct contact with the animal's penis. Also, according to an optional feature of the invention, at the proximal end 10a of the artificial vagina 1, the two half-sleeves 2a, 2b advantageously project out of the half-shells 3a, 3b and comprise two half-collars 20a, 20b which cover the proximal edge 35a, 35b of the half-shells 3a, 3b ( figures 1 and 3 ), so that the proximal edge of the half-shells 3a, 3b can not come into contact with the animal. This avoids the risk of injury to the animal with the half-shells 3a, 3b.

Les deux demi-coques 3a, 3b articulées d'une part, et les deux demi-manchons 2a, 2b d'autre part, peuvent être fabriqués séparément, puis assemblés, chaque demi-manchon 2a, 2b étant fixé sur une demi-coque 3a ou 3b par tout moyen connu de l'homme du métier, et par exemple par collage. Néanmoins, dans une variante préférée de réalisation, les deux demi-coques 3a, 3b articulées et les deux demi-manchons 2a, 2b sont avantageusement réalisés en une seule opération par bi-injection dans un moule.The two half-shells 3a, 3b hinged on the one hand, and the two half-sleeves 2a, 2b on the other hand, can be manufactured separately, then assembled, each half-sleeve 2a, 2b being fixed on a half-shell 3a or 3b by any means known to those skilled in the art, and for example by gluing. Nevertheless, in a preferred variant embodiment, the two articulated half-shells 3a, 3b and the two half-sleeves 2a, 2b are advantageously made in a single operation by bi-injection into a mold.

On a représenté sur la figure 6, un dispositif de serrage 4 apte à exercer une pression supplémentaire sur la paroi externe 23a, 23b des demi-manchons 2a, 2b par l'intermédiaire des ouvertures 30a, 30b en sorte d'accroître la stimulation sur la verge de l'animal en phase d'éjaculation. Le dispositif de serrage 4 comprend un support 40, une tige 41 et un bloc mobile 42. La tige 41 est montée sur le support 40 et le bloc mobile 42 est monté sur la tige 41.We have shown on the figure 6 , a clamping device 4 adapted to exert an additional pressure on the outer wall 23a, 23b of the half-sleeves 2a, 2b via the openings 30a, 30b so as to increase the stimulation on the penis of the animal by ejaculation phase. The clamping device 4 comprises a support 40, a rod 41 and a movable block 42. The rod 41 is mounted on the support 40 and the mobile block 42 is mounted on the rod 41.

Plus particulièrement, le support 40 sensiblement en forme de U comprend une ouverture 400 dans laquelle peut coulisser le bloc mobile 42 par l'intermédiaire de la tige 41. Ainsi, on peut venir placer le vagin artificiel 1 entre la paroi 420 du bloc 42 et la paroi 401 du support 40. De manière avantageuse, les ouvertures 30a et 30b de la coque 3 sont disposées en vis-à-vis de la paroi 420 du bloc 42 d'une part et de la paroi 401 du support 40 d'autre part. De cette manière, on peut venir serrer les deux demi-manchons 2 mous à l'aide de la tige 41. A cet effet, on peut par exemple utiliser une tige 41 filetée pour faire avancer ladite tige 41 dans l'ouverture 400 ou encore utiliser un ressort qui va pousser le bloc 42 vers la paroi 401 du support 40.More particularly, the substantially U-shaped support 40 comprises an opening 400 in which the moving block 42 can slide by means of the rod 41. Thus, the artificial vagina 1 can be placed between the wall 420 of the block 42 and the wall 401 of the support 40. Advantageously, the openings 30a and 30b of the shell 3 are arranged vis-à-vis the wall 420 of the block 42 on the one hand and the wall 401 of the support 40 of other go. In this way, it is possible to tighten the two soft half-sleeves 2 with the aid of the rod 41. For this purpose, it is possible, for example, to use a threaded rod 41 to advance said rod 41 into the opening 400 or else use a spring that will push the block 42 towards the wall 401 of the support 40.

L'opération de collecte de la semence animale au moyen du vagin artificiel 1 est de préférence effectuée conformément à la méthode suivante.

  • 1ère phase :
    L'opérateur saisit la verge de l'animal à l'aide du vagin 1 ouvert (les deux demi-coques 3a, 3b et les deux demi-manchons 2a, 2b ne sont pas joints). Dés que l'extrémité de la verge apparaît, l'opérateur ferme le vagin artificiel 1 sur celle-ci à l'aide des moyens de fermeture 32a, 32b (les deux demi-coques 3a, 3b sont jointes et verrouillées à laide des moyens de fermeture 32a, 32b). L'animal ressent alors une pression qui l'amène en phase d'érection. La mise en oeuvre d'un vagin en deux parties articulées facilite le positionnement de la verge dans le vagin artificiel, et rend le vagin adapté à différentes tailles de verge..
  • 2ème phase :
    L'opérateur positionne et connecte un dispositif de collecte 5 (figure 7) sur l'extrémité distale 10b du vagin et plus particulièrement les demi-collerettes jointives 33a, 33b de la coque 3. Ce dispositif de collecte 5 a pour fonction de recueillir la semence animale qui s'écoule en sortie du vagin artificiel. Le type de dispositif de collecte utilisé est sans importance pour l'invention. Il peut par exemple s'agir d'un réceptacle souple de type sachet ou d'un réceptacle rigide ou semi rigide. De préférence, l'opérateur fixe le vagin artificiel 1 par l'intermédiaire de sa coque 3 sur un support, et n'a ainsi pas besoin de le porter.
  • 3ème phase :
    La pression exercée sur la verge de l'animal par le vagin artificiel 1 lorsque celui-ci est fermé est le plus souvent insuffisante pour amener l'animal en phase d'éjaculation. A cet effet, pour accentuer la pression sur la verge de l'animal, l'opérateur peut exercer une pression supplémentaire sur la paroi externe 23a, 23b des deux demi-manchons 2a, 2b par l'intermédiaire des ouvertures 30a, 30b. L'opérateur peut exercer cette pression supplémentaire manuellement en pinçant manuellement le manchon 2 au niveau des ouvertures 30a, 30b ou en utilisant un dispositif de serrage 4 (tel que représenté à la figure 6) qui pincera le manchon 2 au niveau des deux ouvertures 30a, 30b. La semence de l'animal s'écoule alors en dehors du manchon 2 par l'ouverture ménagée à l'extrémité distale 10b du vagin artificiel, et est recueillie dans le dispositif de collecte 5 monté sur le vagin artificiel 1.
  • 4ème phase :
    Une fois la phase d'éjaculation terminée, la verge est facilement retirée du vagin artificiel 1 en libérant les moyens de verrouillage 32a, 32b, et en ouvrant les deux demi-coques 3a, 3b. L'opérateur retire de son support le vagin artificiel 1 et son dispositif de collecte, et sépare le réceptacle de collecte du vagin artificiel. Lorsque le vagin artificiel (manchon 2 / coque 3) est à usage unique ou devient trop usagé, il est jeté à la poubelle.
The operation of collecting the animal semen by means of the artificial vagina 1 is preferably carried out in accordance with the following method.
  • 1st phase:
    The operator grasps the penis of the animal with the open vagina 1 (the two half-shells 3a, 3b and the two half-sleeves 2a, 2b are not joined). As soon as the end of the penis appears, the operator closes the artificial vagina 1 thereon by means of the closing means 32a, 32b (the two half-shells 3a, 3b are joined and locked using the means closure 32a, 32b). The animal then feels a pressure that leads to the erection phase. Setting Implementation of a two-part articulated vagina facilitates the positioning of the penis in the artificial vagina, and makes the vagina suitable for different penis sizes.
  • 2nd phase:
    The operator positions and connects a collection device 5 ( figure 7 ) on the distal end 10b of the vagina and more particularly the contiguous half-flanges 33a, 33b of the shell 3. The purpose of this collection device 5 is to collect the animal semen flowing out of the artificial vagina. The type of collection device used is irrelevant to the invention. It may for example be a flexible bag-type receptacle or a rigid or semi-rigid receptacle. Preferably, the operator fixes the artificial vagina 1 through its shell 3 on a support, and does not need to wear it.
  • 3rd stage:
    The pressure exerted on the penis of the animal by the artificial vagina 1 when it is closed is usually insufficient to bring the animal into the ejaculation phase. To this end, to increase the pressure on the penis of the animal, the operator can exert additional pressure on the outer wall 23a, 23b of the two half-sleeves 2a, 2b through the openings 30a, 30b. The operator can exert this additional pressure manually by manually pinching the sleeve 2 at the openings 30a, 30b or using a clamping device 4 (as shown in FIG. figure 6 ) which will pinch the sleeve 2 at the two openings 30a, 30b. The semen of the animal then flows outside the sleeve 2 through the opening at the distal end 10b of the artificial vagina, and is collected in the collection device 5 mounted on the artificial vagina 1.
  • 4th stage:
    Once the ejaculation phase is over, the penis is easily removed from the artificial vagina 1 by releasing the locking means 32a, 32b, and opening the two half-shells 3a, 3b. The operator removes the artificial vagina 1 and its collection device from its support, and separates the collection receptacle from the artificial vagina. When the artificial vagina (sleeve 2 / shell 3) is for single use or becomes too worn, it is thrown in the trash.

Il convient de noter que dans une variante, l'ordre des 2ème et 3ème phases peut être inversé.It should be noted that in a variant, the order of 2 nd and 3 rd layers may be reversed.

La méthode ci-dessus peut également être améliorée en réalisant la 1ère phase de la manière suivante. Au cours de la 1ère phase, l'opérateur entrouvre les deux demi-coques 3a, 3b du vagin artificiel et place une chemise sanitaire (encore communément appelée « liner ») dans le logement 21 de réception de la verge en sorte que ladite chemise sanitaire recouvre la paroi interne 22a, 22b des deux demi-manchons 2a, 2b et qu'une partie de cette chemise sanitaire dépasse de l'extrémité proximale 10a. Puis l'opérateur retrousse sur le vagin artificiel la portion de chemise sanitaire qui dépasse de l'extrémité proximale 10a en sorte de recouvrir partiellement ledit vagin artificiel, et permettre le maintien de la chemise sanitaire sur le vagin. Les deux demi-coques 3a, 3b sont ainsi maintenues dans une position dite entrouvert par la chemise sanitaire. Enfin, l'opérateur introduit l'extrémité de la verge de l'animal dans le vagin artificiel, en l'enfilant à l'intérieur de la chemise sanitaire, puis serre les deux demi-coques 3a,3b et ferme le vagin à l'aide des moyens de verrouillage 32a, 32b.The above method can also be improved by making the 1st phase follows. During the 1st phase, the operator half-open the two half-shells 3a, 3b of the artificial vagina and places a sanitary jacket (still commonly known as "liner") in the housing 21 receiving the rod so that said liner sanitary covers the inner wall 22a, 22b of the two half-sleeves 2a, 2b and a portion of the sanitary cover protrudes from the proximal end 10a. Then the operator rolls up on the artificial vagina sanitary shirt portion which protrudes from the proximal end 10a so as to partially cover said artificial vagina, and allow the maintenance of the sanitary shirt on the vagina. The two half-shells 3a, 3b are thus held in a so-called half-open position by the sanitary liner. Finally, the operator introduces the end of the penis of the animal into the artificial vagina, by threading it inside the sanitary shirt, then squeezes the two half-shells 3a, 3b and closes the vagina to the vagina. using the locking means 32a, 32b.

La chemise sanitaire permet de protéger l'intérieur des deux demi-manchons 2a, 2b et est généralement jetée après usage. Elle a également pour fonction d'améliorer l'accrochage de la verge de l'animal dans le vagin artificiel et ainsi d'éviter le glissement de la verge dans le logement 21.The sanitary cover protects the inside of the two half-sleeves 2a, 2b and is usually discarded after use. It also has the function of improving the attachment of the penis of the animal in the artificial vagina and thus prevent slippage of the penis in the housing 21.

L'invention n'est pas limitée à la variante des figures annexées, qui a été décrite à titre d'exemple non limitatif et non exhaustif de l'invention. En particulier, les deux ouvertures 30a, 30b des demi-coques 3a, 3b ne sont pas nécessairement identiques. Le vagin artificiel 1 de l'invention ne comporte pas nécessairement deux ouvertures 30a, 30b, une seule ouverture 30a ou 30b pourrait suffire pour exercer une pression radiale, manuelle ou à l'aide du dispositif de serrage, en sorte d'amener l'animal en phase d'éjaculation. Les deux demi-coques ne sont pas nécessairement articulées. Dans une autre variante, les deux demi-coques 3a, 3b (avec leur demi-manchon 2a, 2b) peuvent former deux ensembles séparés et pourvus de moyens permettant leur assemblage en sorte de former la coque 3.The invention is not limited to the variant of the appended figures, which has been described by way of nonlimiting and non-exhaustive example of the invention. In in particular, the two openings 30a, 30b of the half-shells 3a, 3b are not necessarily identical. The artificial vagina 1 of the invention does not necessarily have two openings 30a, 30b, a single opening 30a or 30b could be sufficient to exert a radial pressure, manual or with the aid of the clamping device, so as to bring the animal in ejaculation phase. The two half-hulls are not necessarily articulated. In another variant, the two half-shells 3a, 3b (with their half-sleeve 2a, 2b) can form two separate assemblies and provided with means allowing their assembly so as to form the shell 3.
