Description

La présente invention concerne. les dispositifs d'insémination artificielle pour petits animaux et plus particulièrement pour oiseaux de basse-cour, dits " mitraillettes " et qui sont du type comprenant d'une part, un boîtier qui comporte un passage cylindrique auquel sont associés des moyens d'éjection de semence et d'autre part, un tube réservoir de semence dit " paillette " qui est fixé par des moyens dé.maintien en regard de ce passage de manière à être situé entièrement en avant du boitier.The present invention relates. artificial insemination devices for small animals and more particularly for backyard birds, known as "machine guns" and which are of the type comprising on the one hand, a housing which has a cylindrical passage with which are associated means for ejecting seed and on the other hand, a so-called "straw" seed tank tube which is fixed by means of support opposite this passage so as to be situated entirely in front of the housing.

Lorsque les moyens d'éjection de semence sont constitués par une tige-piston montée coulissante dans le passage du boîtier et munie de moyens d'avance pas à pas, une telle " mitraillette " permet, à partir d'un volume donné de semence (ou autre produit injecté contenu dans le tube réservoir, d'effectuer plusieurs opérations successives d'injection n'utilisant chacune qu'une fraction donnée, ou dose, connue et parfaitement déterminée, ce qui autorisé ainsi l'insémination successive et immédiate de plusieurs animaux.When the semen ejection means consist of a piston rod slidingly mounted in the passage of the housing and provided with step-by-step advance means, such a "machine gun" makes it possible, from a given volume of semen ( or other injected product contained in the reservoir tube, to perform several successive injection operations each using only a given fraction, or dose, known and perfectly determined, which thus authorizes the successive and immediate insemination of several animals .

. On connaît déjà, par exemple, par le brevet français n° 79 D2020, des dispositifs du type considéré, plus particulièrement utilisés pour l'insémination des pintades. Dans ces dispositifs toutefois, le passage de guidage est prévu dans un élément qui présente une partie en saillie par rapport au boîtier,et le tube-réservoir , dont le diamètre intérieur est pratiquement égal au diamètrede la tige-piston, s'applique uniquement par sa tranche arrière contre la face frontale de cette partie en saillie. Les moyens de maintien sont fournis par la présence d'une gaine protectrice souple qui enveloppe l'ensemble constitué par le tube-réservoir et ladite partie en saillie et est fixée à son extrémité arrière sur cette dernière,soit par une bague de serrage coopérant avec une surface extérieure convergente: de cette partie, soit par élasticité sur une nervure, par exemple spirale, prévue sur cette même partie, tandis qu'à son extrémité avant, cette gaine offre une forme convergente ou arrondie qui sert de butée à l'extrémité du tube-réservoir . Cette forme convergente ou arrondie d'une part, facilite la pénétration dans le cloaque et d'autre part évite de blesser la paroi de ce dernier. En outre, l'orifice de dimension réduite qui est délimité par cette extrémité convergente ou arrondie joue un rôle d'ajutage. et permet, sous l'effet de l'effort mécanique fourni par la tige piston qui pénètre dans le tube-réservoir, d'évacuer sous pression la semence sous forme d'un jet, sans formerde goutte " perlant " à l'extrémité de la gaine et qui, demeurent fixée à celle-ci par capillarité, serait perdue pour l'insémination, entrainant ainsi d'une part, une erreur dans la dose effectivement injectée et d'autre part, un coût supérieur de l'opération en raison du prix très élevé de la semence.. Are already known, for example, from French Patent No. 79 D2020, devices of the type considered, more particularly used for the insemination of guinea fowl. In these devices, however, the guide passage is provided in an element which has a projecting portion relative to the housing, and the reservoir tube, the internal diameter of which is practically equal to the diameter of the piston rod, is applied only by its rear edge against the front face of this projecting part. The holding means are provided by the presence of a flexible protective sheath which envelops the assembly constituted by the reservoir tube and said projecting part and is fixed at its rear end to the latter, either by a clamping ring cooperating with a converging outer surface: of this part, either by elasticity on a rib, for example spiral, provided on this same part, while at its front end, this sheath offers a convergent or rounded shape which serves as a stop at the end of the reservoir tube. This convergent or rounded shape on the one hand, facilitates penetration into the cesspool and on the other hand avoids injuring the wall of the latter. In addition, the reduced-size orifice which is delimited by this converging or rounded end plays a nozzle role. and allows, under the effect of the mechanical force provided by the piston rod which penetrates into the reservoir tube, to evacuate the seed under pressure in the form of a jet, without forming a "beading" drop at the end of the sheath and which, remaining fixed to the latter by capillary action, would lost for insemination, thus causing on the one hand, an error in the dose actually injected and on the other hand, a higher cost of the operation due to the very high price of the semen.

Or, il se trouve que, dans le cas d'insémination de pintades, un tube-réservoir tel que décrit ci-dessus présente une capacité d'environ 0,5 cm3 et permet donc d'inséminer 20 à 25 animaux compte tenu de la concentration de l'éjaculat contenu dans ce tube. Pour d'autres espèces, par exemple pour les animaux du genre gallus, tels que les poules, la concentration doit être différente et la capacité précitée ne permettrait que l'obtention d'environ 10 doses, ce qui exigerait un changement beaucoup trop fréquent du tube-réservoir et donc une perte de temps. En outre, le coût du tube-réservoir accroît également le prix de revient par dose injectée. Enfin, la gaine, généralement réalisée en chlorure de polyvinyle, comme le tube-réservoir, est également d'un prix de revient relativement élevée et grève encore le coût de l'utilisation.However, it turns out that, in the case of insemination of guinea fowl, a reservoir tube as described above has a capacity of approximately 0.5 cm 3 and therefore makes it possible to inseminate 20 to 25 animals taking into account the concentration of the ejaculate contained in this tube. For other species, for example for animals of the genus gallus, such as hens, the concentration must be different and the abovementioned capacity would only allow the obtaining of approximately 10 doses, which would require a far too frequent change of the tank tube and therefore a waste of time. In addition, the cost of the reservoir tube also increases the cost price per dose injected. Finally, the sheath, generally made of polyvinyl chloride, like the reservoir tube, is also of a relatively high cost price and further burdens the cost of use.

C'est pourquoi, l'invention a pour but de supprimer ces divers inconvénients, en premier lieu en réduisant le prix de revient de la partie amovible et remplacable constituée précédemment par le tube-réservoir et la gaine.This is why the invention aims to eliminate these various drawbacks, firstly by reducing the cost price of the removable and replaceable part previously constituted by the reservoir tube and the sheath.

A cet effet, l'invention a pour objet un dispositif du type précité, caractérisé en ce les moyens de maintien du tube-réservoir sur le boitier sont directement prévus entre l'extrémité arrière de ce tube et ce boîtier, cette extrémité arrière s'engageant par emboîtement sur une partie en saillie solidaire du boîtier autour dudit passage , tandis que l'extrémité avant de ce même tube-réservoir présente une forme convergente ou arrondie.To this end, the invention relates to a device of the aforementioned type, characterized in that the means for holding the reservoir tube on the housing are directly provided between the rear end of this tube and this housing, this rear end s' engaging by interlocking on a projecting part integral with the housing around said passage, while the front end of this same reservoir tube has a convergent or rounded shape.

Grâce à cet agencement, il n'est plus nécessaire de prévoir une gaine spéciale supplémentaire assurant d'une part, le maintien du tube réservoir sur le boîtier et d'autre part, une pénétration aisée et sans blessure.With this arrangement, it is no longer necessary to provide an additional special sheath ensuring on the one hand, the maintenance of the reservoir tube on the housing and on the other hand, easy penetration and without injury.

En outre, dans un mode de réalisation particulièrement avantageux, la disposition précédente permet de prévoir que le diamètre intérieur du tube-réservoir soit notablement supérieur à celui du passage du guidage, et donc au diamètre de la tige piston, ce qui permét ainsi de disposer de tubes d'une capacité nettement plus grande et pouvant par exemple contenir également, 20 à 25 doses de semence de l'espèce gallus si cette capacité atteint 1,2 cm3..In addition, in a particularly advantageous embodiment, the preceding arrangement makes it possible to provide that the inner diameter of the reservoir tube is significantly greater than that of the guide passage, and therefore the diameter of the piston rod, which thus makes it possible to have tubes of a significantly greater capacity and which can, for example, also contain, 20 to 25 seed doses of the gallus species if this capacity reaches 1.2 cm3.

De préférence, la partie en saillie solidaire du boîtier peut présenter extérieurement et successivement suivant la direction du passage de guidage, une surface de maintien présentant les moyens de maintien du tube-réservoir et une surface cylindrique libre de diamètre inférieur au diamètre intérieur du tube-réservoir. Cette seconde surface pénètre librement dans le tube-réservoir et sert plus particulièrement d'appui au bouchon-piston qui est normalement prévu à cette extrémité à l'intérieur du tube et sert à éjecter la semence sous l'action delà tige-piston.Preferably, the projecting part integral with the housing can have, externally and successively in the direction of the guide passage, a holding surface having the means for holding the reservoir tube and a free cylindrical surface with a diameter less than the inside diameter of the tube tank. This second surface penetrates freely into the reservoir tube and more particularly serves as a support for the piston stopper which is normally provided at this end inside the tube and is used to eject the seed under the action of the piston rod.

Avantageusement, il peut être prévu que la pièce de serrage présente, du côté opposé au boîtier, une partie allongée comportant un passage central cylindrique de "diamètre à peu près égal au diamètre extérieur du tube-réservoir. Cette partie allongée sert ainsi de guide au tube -réservoir sur une partie de sa longueur et lui assure ainsi une certaine rigidité qui s'ajoute à sa rigidité propre pour remplacer celle qui ne lui est plus fournie par la gaine qui a été supprimée.Advantageously, provision may be made for the clamping piece to present, on the side opposite to the housing, an elongated part comprising a cylindrical central passage of "diameter approximately equal to the outside diameter of the reservoir tube. This elongated part thus serves as a guide for the tube -reservoir over a part of its length and thus provides it with a certain rigidity which is added to its own rigidity to replace that which is no longer supplied to it by the sheath which has been removed.

D'autres caractéristiques et avantages de l'invention ressortiront de la description qui va suivre, à titre d'exemple non limitatif et en regard des dessins annexés, sur lesquels :

  • - la Fig. 1 représente une vue partielle et en coupe d'un dispositif suivant un mode de réalisation particulier conforme à l'invention.
  • - la Fig. 2 représente une vue partielle et à plus grande échelle de la zone de maintien du tube-réservoir sur le boîtier.
Other characteristics and advantages of the invention will emerge from the description which follows, by way of nonlimiting example and with reference to the appended drawings, in which:
  • - Fig. 1 shows a partial view in section of a device according to a particular embodiment according to the invention.
  • - Fig. 2 shows a partial view on a larger scale of the holding zone of the reservoir tube on the housing.

Ce dispositif se présente sous la forme d'un pistolet constitué d'un boîtier 1 présentant une face avant 1a dans laquelle est fixée un bloc 2 qui présente une partie en forme de canon 2a en saillie par rapport à la face 1a et orientée suivant une direction X-X. Ce corps 2 et sa partie en saillie 2a présentent un passage de guidage cylindrique 3 disposé suivant la direction X-X et à l'intérieur de laquelle est montée coulissante une tige-piston 4 qui s'étend en arrière du corps 2 à l'intérieur du boîtier t et est munie de moyens d'avance pas à pas 5 qui comprennent des plaquettes percées 5a, des ressorts 5b et des butées 5c et qui ne seront pas décrits plus en détail, une description en étant déjà donnée dans le brevet français n° 79 020 20. Ces moyens d'avance 5 sont commandés à l'aide d'une détente-pistolet 6 qui fait saillie à travers une crosse 7 du boîtier disposée latéralement par.rapport à l'axe X-X.This device is in the form of a pistol consisting of a housing 1 having a front face 1a in which is fixed a block 2 which has a barrel-shaped part 2a projecting from the face 1a and oriented along a direction XX. This body 2 and its projecting part 2a have a passage cylindrical guide 3 disposed in the direction XX and inside which is slidably mounted a piston rod 4 which extends behind the body 2 inside the housing t and is provided with means for advancing not step 5 which include pierced plates 5a, springs 5b and stops 5c and which will not be described in more detail, a description being already given in French patent n ° 79,020 20. These means of advance 5 are controlled using a trigger gun 6 which projects through a stock 7 of the housing disposed laterally par.rapport the axis XX.

La partie en saillie 2a du bloc 2 comporte extérieurement et successivement â partir de la face la du boîtier et suivant la direction X-X, une surface cylindrique présentant un filetage de fixation 8, puis une portée cylindrique 9 de diamètre légèrement inférieur, et, après un épaulement radial 10, une surface convergente tronconique à angle relativement faible 11 et enfin une partie cylindrique 12 se terminant par une extrémité biseautée 13.The projecting part 2a of the block 2 comprises externally and successively from the face 1a of the housing and in the direction XX, a cylindrical surface having a fixing thread 8, then a cylindrical seat 9 of slightly smaller diameter, and, after a radial shoulder 10, a frustoconical converging surface at a relatively small angle 11 and finally a cylindrical part 12 ending in a beveled end 13.

A ce pistolet est associé un tube-réservoir ou paillette 14 réalisé par exemple, en chlorure de polyvinyle et qui contient de la semence animale, son extrémité arrière étant obturée à l'aide d'un bouchon-piston 15. Le. diamètre intérieur de cette paillette est très légèrement supérieur,avec un jeu e, au diamètre de la. portée cylindrique 12 du canon 2a. Sa portion arrière extrême 14a est engagée à force, par emboîtement,sur la portée tronconique 11 du canon, l'évasement de cette extrémité normalement cylindrique assurant un appui net sur cette pièce. Il résulte de cet emboîtement que le canon 2a pénètre à l'intérieur du tube-réservoir 14 et que son extrémité 13 sert de butée au bouchon-piston 15.With this gun is associated a reservoir tube or flake 14 made for example, of polyvinyl chloride and which contains animal semen, its rear end being closed off with the aid of a plunger stopper 15. Le. internal diameter of this flake is very slightly greater, with a clearance e, than the diameter of the. cylindrical surface 12 of the barrel 2a. Its extreme rear portion 14a is forcibly engaged, by interlocking, on the frustoconical surface 11 of the barrel, the flaring of this normally cylindrical end ensuring clear support on this part. It follows from this interlocking that the barrel 2a penetrates inside the reservoir tube 14 and that its end 13 serves as a stop for the piston stopper 15.

Il peut être également avantageusement prévu une fente longitudinale 14b sur la portion arrière extrême 14a d'emboîtement, cette fente ayant pour fonction de faciliter, d'une part, l'emmanchement de la paillette lorsqu'on la place sur le canon 2a du pistolet, et d'autre part, de faciliter également son éjection une fois qu'elle a été totalement utilisée.A longitudinal slot 14b can also advantageously be provided on the extreme rear fitting portion 14a, this slot having the function of facilitating, on the one hand, the fitting of the straw when it is placed on the barrel 2a of the pistol , and on the other hand, also to facilitate its ejection once it has been fully used.

En outre, le bouchon-piston 15 qui comporte trois parties juxtaposées dans le sens axial, se trouve coloré dans celle 15a de ces parties qui se trouve située au milieu de sorte que, lorsque le bouchon parvient presque à l'extrémité avant de la paillette 14b, cette partie colorée sert de signal optique pour l'inséminateur qui sait alors qu'il arrive pratiquement à la fin de la semence contenue dans la paillette et qu'il ne lui reste plus que deux ou trois doses à inséminer. Ce bouchon permet, par ailleurs, une aspiration aisée et rapide du liquide dans la paillette avant le montage de celle-ci sur le pistolet, et ceci à partir d'une ampoule contenant le liquide (tel que par exemple de la semence de coq récoltée, ou tout autre liquide à injecter). A cet effet, on introduit l'extrémité de la paillette opposée à son extrémité 14a, par le col de l'ampoule, dans le liquide à aspirer, et, à l'aide de la bouche ou d'un tuyau relié à une petite poire, on aspire ce liquide d'une manière simple, sans avoir à prévoir d'appareillage spécial et compliqué dans ce but. En outre, la partie centrale du bouchon, constituée de poudre spéciale, se gélifie instantanément sous l'action du liquide introduit dans la paillette, assurant ainsi une étanchéité parfaite à l'extrémité où se trouve ce bouchon après aspiration.In addition, the plug-piston 15 which has three parts juxtaposed in the axial direction, is colored in that 15a of these parts which is located in the middle so that, when the plug reaches almost the front end of the straw 14b, this the colored part serves as an optical signal for the inseminator who then knows that he is almost at the end of the seed contained in the straw and that he has only two or three doses left to inseminate. This cap allows, moreover, an easy and rapid aspiration of the liquid in the straw before mounting it on the gun, and this from a bulb containing the liquid (such as for example of the seed of rooster harvested , or any other liquid to be injected). For this purpose, we introduce the end of the straw opposite its end 14a, through the neck of the bulb, into the liquid to be sucked, and, using the mouth or a pipe connected to a small pear, we suck this liquid in a simple way, without having to provide special and complicated equipment for this purpose. In addition, the central part of the stopper, made of special powder, instantly gels under the action of the liquid introduced into the straw, thus ensuring a perfect seal at the end where this stopper is located after aspiration.

Cet ensemble est complété par une pièce de serrage 16 de révolution et qui comporte successivement de l'arrière vers l'avant une partie de raccord 16a munie d'un filetage intérieur qui se visse sur le filetage 8 du canon, puis un chambrage 16b qui laisse subsister un certain jeu par rapport à la portée 9 et l'épaulement 10 de ce canon, et une partie extrême comportant un alésage cylindrique intérieur de diamètre très légèrement supérieur,avec un jeu e,au diamètre extérieur du tube réservoir 14, le bord arrière de cet alésage présentant un arrondi ou congé 16d qui s'appurèsur la partie évasée 14a du tube -réservoir et sur la portée tronconique 11 du canon. Il est important de noter que l'arrondi 16d, qui est poli, permet d'éviter un sectionnement du tube-réservoir 14 à ce niveau et, par conséquent, un échappement de ce dernier hors du pistolet lors de l'actionnement de la tige-piston 4. La partie cylindrique avant 16c s'étend sur une certaine longueur autour du tube réservoir 14 de manière à renforcer le positionnement et la rigidité de celui-ci, et la longueur de ce guidage peut atteindre par exemple le tiers,la moitié ou même plus de la moitié de la longueur du tube 14.This assembly is completed by a clamping piece 16 of revolution and which successively comprises from the rear towards the front a connection part 16a provided with an internal thread which is screwed onto the thread 8 of the barrel, then a recess 16b which leaves a certain clearance with respect to the range 9 and the shoulder 10 of this barrel, and an extreme part comprising an inner cylindrical bore of diameter very slightly greater, with a clearance e, than the outside diameter of the reservoir tube 14, the edge rear of this bore having a rounded or leave 16d which rests on the flared part 14a of the tube -reservoir and on the frustoconical surface 11 of the barrel. It is important to note that the rounded 16d, which is polished, makes it possible to avoid sectioning of the reservoir tube 14 at this level and, consequently, an escape of the latter out of the gun during actuation of the rod. -piston 4. The front cylindrical part 16c extends over a certain length around the reservoir tube 14 so as to reinforce the positioning and the rigidity of the latter, and the length of this guide can reach for example one third, half or even more than half the length of the tube 14.

Ce dernier-tube réservoir 14 présente à son extrémité avant une partie convergente tronconique 14b qui se termine par un rebord 14c replié intérieurement en forme d'ourlet et pouvant même revenir axialement vers l'intérieur du tube-réservoir, ce rebord délimitant un orifice d'éjection 14d.This latter reservoir tube 14 has at its front end a frustoconical convergent part 14b which ends in a rim 14c folded internally in the form of a hem and which can even return axially towards the interior of the reservoir tube, this rim delimiting an orifice ejection 14d.

Le fonctionnement du dispositif ainsi décrit est le suivant :

  • On dévisse la pièce de serrage 46 et on emboîte un tube-réservoir 14 par son extrémité arrière sur le canon 2a du .pistolet, à la suite de quoi, on recouvre ce tube par la prèce de serrage 16 qui est enfin serrée à l'aide du filetage 16a.
The operation of the device thus described is as follows:
  • We unscrew the clamping piece 46 and we fit a reservoir tube 14 by its rear end on the barrel 2a of the pistol, after which, we cover this tube with the clamping piece 16 which is finally tightened to the using thread 16a.

L'inséminateur peut alors introduire le tube 14 dans le cloaque de l'animal et, à l'aide de la détente 6, actionner la tige-piston 4 qui, par l'intermédiaire du bouchon 15, repousse la dose voulue de semence à travers l'orifice 14d de la paillette, l'étranglement du jet ainsi obtenu favorisant la qualité de l'insémination.The inseminator can then introduce the tube 14 into the cesspool of the animal and, using the trigger 6, actuate the piston rod 4 which, by means of the plug 15, pushes the desired dose of semen to through the orifice 14d of the straw, the throttling of the jet thus obtained promoting the quality of the insemination.

Après avoir opéré plusieurs fois de la sorte sur différents animaux en utilisant le nombre de doses contenu dans la paillette, l'inséminateur peut remplacer cette dernière par démon-. tage et remontage de la pièce de serrage 16.After having operated several times in this way on different animals using the number of doses contained in the straw, the inseminator can replace the latter with dismount. clamping and reassembly of the clamping piece 16.
