Description

Sonde d'insémination artificielle d'un animal d'élevage tel qu'un porcin  Artificial insemination probe of a farmed animal such as a pig
L'invention a trait aux sondes d'insémination artificielle d'un animal d'élevage tel qu'un porcin. The invention relates to artificial insemination probes of a farmed animal such as a pig.
On sait que pour opérer l'insémination artificielle de certains animaux d'élevage, et en particulier les animaux femelle porcin, on utilise une sonde d'insémination artificielle comportant un corps allongé et un embout disposé à une extrémité du corps allongé, lequel embout est configuré pour se positionner dans le col de l'utérus de l'animal, on insère cette sonde dans l'appareil génital de l'animal avec l'embout le premier jusqu'à ce qu'il soit positionné dans le col de l'utérus et on transfère une dose de semence avec la sonde, qui est munie d'un conduit interne débouchant par un orifice situé à l'extrémité distale de l'embout.  It is known that in order to effect artificial insemination of certain farm animals, and in particular porcine female animals, an artificial insemination probe comprising an elongated body and a tip disposed at one end of the elongate body, which endpiece is configured to position itself in the cervix of the animal, this probe is inserted into the genitalia of the animal with the tip first until it is positioned in the cervix of the animal. uterus and transfer a dose of semen with the probe, which is provided with an inner conduit opening through an orifice located at the distal end of the tip.
On connaît déjà, notamment par la demande de brevet européen EP 0 861 637 ou par la demande internationale PCT WO 2008/055665, une telle sonde dont l'embout comporte, entre une extrémité proximale située du côté du corps allongé et une extrémité distale située du côté opposé au corps allongé, un ensemble de collerettes latérales s'étendant vers l'extérieur à partir d'un fût central.  Already known, in particular by the European patent application EP 0 861 637 or by the international application PCT WO 2008/055665, such a probe whose tip comprises, between a proximal end located on the side of the elongated body and a distal end located on the opposite side to the elongate body, a set of lateral flanges extending outwardly from a central shaft.
Cet ensemble de collerettes permet de donner à l'embout la souplesse requise pour pouvoir pénétrer dans le col de l'utérus et pour rester en place dans celui-ci.  This set of collars makes it possible to give the tip the flexibility required to be able to penetrate into the neck of the uterus and to remain in place therein.
L'invention vise à améliorer les performances des sondes comportant un embout de ce type.  The invention aims to improve the performance of probes comprising a tip of this type.
L'invention propose à cet effet une sonde d'insémination artificielle d'un animal d'élevage tel qu'un porcin, comportant un corps allongé et un embout disposé à une extrémité du corps allongé, lequel embout est configuré pour se positionner dans le col de l'utérus de l'animal, s'étend entre une extrémité proximale située du côté du corps allongé et une extrémité distale située du côté opposé au corps allongé, avec entre l'extrémité proximale et l'extrémité distale un ensemble de collerettes latérales s'étendant vers l'extérieur à partir d'un fût central ; caractérisée en ce que la collerette la plus proche de l'extrémité proximale présente à sa base un renflement annulaire configuré pour que cette collerette présente une brusque variation d'épaisseur à la jonction entre le renflement annulaire et sa portion périphérique située plus à l'extérieur que le renflement annulaire. The invention proposes for this purpose an artificial insemination probe of a farm animal such as a pig, comprising an elongate body and a tip disposed at one end of the elongated body, which endpiece is configured to position itself in the the uterine cervix of the animal, extends between a proximal end located on the side of the elongate body and a distal end located on the opposite side of the elongate body, with between the proximal end and the distal end a set of side flanges extending outwardly from a central shaft; characterized in that the collar closest to the proximal end has at its base an annular bulge configured so that this collar has a sudden change in thickness at the junction between the annular bulge and its peripheral portion located further outside than the annular bulge.
Du fait du renflement annulaire, la collerette la plus proche de l'extrémité proximale est relativement flexible dans sa partie périphérique située au-delà du renflement vers l'extérieur, mais est relativement rigide au niveau du renflement.  Due to the annular bulge, the flange closest to the proximal end is relatively flexible in its peripheral portion beyond the bulge outwardly, but is relatively rigid at the bulge.
Etant donné que la collerette la plus proche de l'extrémité proximale est prévue pour être située à la jonction entre le vagin et le col de l'utérus de l'animal, la conformation particulière de cette collerette est favorable à l'étanchéité entre l'embout et le col de l'utérus.  Since the collar closest to the proximal end is intended to be located at the junction between the vagina and the cervix of the animal, the particular conformation of this collar is favorable to the seal between the mouthpiece and the cervix.
L'embout de la collerette selon l'invention offre ainsi d'excellentes performances, puisqu'une telle étanchéité évite les pertes de semence par reflux.  The tip of the collar according to the invention thus offers excellent performance, since such a seal avoids losses of semen by reflux.
Selon des caractéristiques avantageuses de mise en œuvre de la sonde d'insémination selon l'invention :  According to advantageous characteristics of implementation of the insemination probe according to the invention:
- ledit renflement annulaire est situé du côté de l'extrémité proximale ;  said annular bulge is situated on the side of the proximal end;
- ledit renflement annulaire augmente d'épaisseur entre ledit fût central et un épaulement qui forme ladite brusque variation d'épaisseur ;  said annular bulge increases in thickness between said central barrel and a shoulder which forms said sudden variation in thickness;
- au moins une dite collerette latérale, parmi les plus proches de l'extrémité distale, comporte au moins une encoche s'étendant de l'extrémité libre vers le centre ;  at least one said lateral flange, among the closest to the distal end, comprises at least one notch extending from the free end towards the center;
- au moins une collerette latérale parmi les plus proches de l'extrémité distale présente deux dites encoches diamétralement opposées ;  at least one lateral flange among those closest to the distal end has two said diametrically opposite notches;
- ledit fût central comporte une première portion et une deuxième portion, avec la deuxième portion qui est du côté de l'extrémité distale et avec le diamètre externe de la deuxième portion qui a un plus petit diamètre que la première portion ; - ledit ensemble de collerettes comporte dans une position intermédiaire entre l'extrémité proximale et l'extrémité distale, des collerettes de plus petit diamètre, de sorte que ledit ensemble présente un contour ayant une gorge dans ladite position intermédiaire ; said central drum comprises a first portion and a second portion, with the second portion being on the side of the distal end and with the outer diameter of the second portion having a smaller diameter than the first portion; said set of flanges comprises, in an intermediate position between the proximal end and the distal end, flanges of smaller diameter, so that said assembly has an outline having a groove in said intermediate position;
- ledit ensemble comporte de part et d'autre desdites collerettes de plus petit diamètre, des groupes de collerettes ayant le même diamètre ;  said assembly comprises, on either side of said smaller-diameter collars, groups of collars having the same diameter;
- dans ledit ensemble, les collerettes autres que ladite collerette la plus proche de l'extrémité proximale sont à épaisseur constante et à écart axial constant entre les collerettes voisines ; et/ou  in said assembly, the flanges other than said collar closest to the proximal end are of constant thickness and at constant axial spacing between the neighboring flanges; and or
- lesdites collerettes autres que la collerette la plus proche de l'extrémité proximale ont toutes la même épaisseur.  said flanges other than the flange closest to the proximal end all have the same thickness.
L'exposé de l'invention sera maintenant poursuivi par la description détaillée d'un exemple de réalisation, donnée ci-après à titre illustratif et non limitatif, en référence aux dessins annexés.

- la figure 5 est la vue en coupe repérée par V-V sur la figure 4. FIG. 5 is the sectional view indicated by V-V in FIG. 4.
La sonde d'insémination artificielle 10 illustrée sur les dessins comporte un corps allongé 1 1 et un embout 12 disposé à une extrémité du corps allongé 1 1 . The artificial insemination probe 10 illustrated in the drawings comprises an elongate body 11 and a tip 12 disposed at one end of the elongate body 11.
Dans l'exemple illustré, la sonde 10 est spécialement conçue pour l'insémination artificielle d'un animal femelle porcin.  In the illustrated example, the probe 10 is specially designed for artificial insemination of a porcine female animal.
L'embout 12 est configuré pour être positionné dans le col de l'utérus d'un tel animal. L'embout 12 s'étend entre une extrémité proximale 14 située du côté du corps allongé 1 1 et une extrémité distale 13 située du côté opposé au corps allongé 1 1 . The tip 12 is configured to be positioned in the cervix of such an animal. The tip 12 extends between a proximal end 14 located on the side of the elongated body 1 1 and a distal end 13 located on the opposite side to the elongated body January 1.
L'embout 12 présente à son extrémité distale 13 un orifice 15 par lequel débouche un conduit 16 interne à la sonde 10.  The tip 12 has at its distal end 13 an orifice 15 through which opens a conduit 16 internal to the probe 10.
Entre l'extrémité proximale 14 et l'extrémité distale 13, l'embout 12 comporte un ensemble 17 de collerettes latérales, ici au nombre de onze référencées par 18 à 28 dans l'ordre de proximité par rapport au corps allongé 1 1 , avec la collerette 18 qui est la plus proche du corps allongé 1 1 et la collerette 28 la plus éloignée.  Between the proximal end 14 and the distal end 13, the tip 12 comprises an assembly 17 of lateral collars, here in number of eleven referenced 18 to 28 in the order of proximity relative to the elongate body 1 1, with the flange 18 which is closest to the elongate body 1 1 and the flange 28 furthest away.
Chacune des collerettes 18 à 28 saille d'un fût central 30 à contour externe circulaire.  Each of the flanges 18 to 28 protrudes from a central shaft 30 with a circular outer contour.
Le fût 30 comporte une nervure annulaire 29 à l'extrémité distale 13. La nervure annulaire 29 entoure l'orifice 15.  The barrel 30 has an annular rib 29 at the distal end 13. The annular rib 29 surrounds the orifice 15.
Le fût 30 comporte une première portion 31 dont saillent les collerettes 18 à 23 et une deuxième portion 32 dont saillent les collerettes 24 à 28.  The shaft 30 comprises a first portion 31 from which the flanges 18 to 23 project and a second portion 32 from which the flanges 24 to 28 project.
Le diamètre externe de la portion 32 est plus petit que le diamètre externe de la portion 31 .  The outer diameter of the portion 32 is smaller than the outer diameter of the portion 31.
Les collerettes 18 à 22 et 25 à 27 ont ici le même diamètre. The collars 18 to 22 and 25 to 27 here have the same diameter.
Les collerettes 23 et 24 ont le même diamètre, beaucoup plus petit que le diamètre des collerettes 18 à 22 et 25 à 27. The flanges 23 and 24 have the same diameter, much smaller than the diameter of the flanges 18 to 22 and 25 to 27.
La collerette 28 a un diamètre intermédiaire entre celui des collerettes 23 et 24 et celui des collerettes 18 à 22 et 25 à 27.  The flange 28 has a diameter intermediate that of the flanges 23 and 24 and that of the flanges 18 to 22 and 25 to 27.
L'ensemble 17 de collerettes présente ainsi un contour général globalement cylindrique ayant le diamètre des collerettes 18 à 22 et 25 à 27 avec une gorge médiane ayant le diamètre des collerettes 23 et 24, et une partie évasée au voisinage de l'extrémité distale 13 grâce à la collerette 28 et à la nervure annulaire 29. Cette partie évasée a son diamètre qui diminue au fur et à mesure que l'on se rapproche de l'extrémité distale 13.  The assembly 17 of flanges thus has a generally cylindrical overall contour having the diameter of the flanges 18 to 22 and 25 to 27 with a median groove having the diameter of the flanges 23 and 24, and a flared portion in the vicinity of the distal end 13 thanks to the flange 28 and the annular rib 29. This flared portion has its diameter which decreases as one approaches the distal end 13.
On notera qu'ici la paroi latérale de la nervure annulaire 28 est également évasée, dans le même sens. Ici, l'écart axial entre deux collerettes voisines est le même dans tout l'ensemble 17. Note that here the side wall of the annular rib 28 is also flared, in the same direction. Here, the axial distance between two neighboring collars is the same throughout the assembly 17.
Ici, chacune des collerettes 19 à 28 présente une épaisseur constante sur toute son extension, c'est-à-dire depuis le fût 30 jusqu'à son extrémité libre.  Here, each of the flanges 19 to 28 has a constant thickness throughout its extension, that is to say from the shaft 30 to its free end.
L'épaisseur qu'a chacune des collerettes 19 à 28 est légèrement plus petite que l'écart axial entre deux collerettes voisines.  The thickness that each of the flanges 19 to 28 is slightly smaller than the axial distance between two adjacent flanges.
Comme on le voit bien sur les figures 3 et 4, la collerette 18, qui est la plus proche de l'extrémité proximale 14, a le même profil que les autres collerettes si ce n'est qu'elle présente du côté de l'extrémité proximale 14, un renflement annulaire 35 situé à sa base, c'est-à-dire dans sa partie par laquelle la collerette 18 se raccorde au fût 30.  As can be seen in FIGS. 3 and 4, the flange 18, which is the closest to the proximal end 14, has the same profile as the other flanges, except that it presents on the side of the proximal end 14, an annular bulge 35 located at its base, that is to say in its part by which the collar 18 is connected to the barrel 30.
Le renflement annulaire 35 a un profil tel que la collerette 18 présente une brusque variation d'épaisseur à la jonction entre le renflement annulaire 35 et sa portion périphérique située plus à l'extérieur que le renflement annulaire 35.  The annular bulge 35 has a profile such that the flange 18 has a sudden variation in thickness at the junction between the annular bulge 35 and its peripheral portion situated further outside than the annular bulge 35.
Ici, la portion périphérique de la collerette 18 (portion située plus à l'extérieur que le renflement 35) a une épaisseur constante, qui est la même que l'épaisseur des collerettes 19 à 28.  Here, the peripheral portion of the flange 18 (portion located more outward than the bulge 35) has a constant thickness, which is the same as the thickness of the flanges 19 to 28.
Le renflement 35 présente un épaulement 36 à sa jonction avec la portion périphérique de la collerette 18, c'est-à-dire que le renflement 35 est délimité vers l'extérieur par l'épaulement 36.  The bulge 35 has a shoulder 36 at its junction with the peripheral portion of the collar 18, that is to say that the bulge 35 is delimited outwards by the shoulder 36.
L'épaisseur du renflement 35 diminue entre le fût 30 et l'épaulement The thickness of the bulge 35 decreases between the barrel 30 and the shoulder
36. 36.
L'épaulement 36 se raccorde à chaque extrémité au reste de la collerette 18 par un congé arrondi. Entre l'épaulement 36 et le fût 30, le renflement annulaire 35 présente un profil incurvé.  The shoulder 36 is connected at each end to the rest of the collar 18 by a rounded leave. Between the shoulder 36 and the shank 30, the annular bulge 35 has a curved profile.
Au niveau de l'épaulement 36, le renflement annulaire 35 a une épaisseur qui est à peu près le double de celle de la portion périphérique de la collerette 18.  At the shoulder 36, the annular bulge 35 has a thickness which is approximately twice that of the peripheral portion of the collar 18.
L'embout 12 est fait en matière plastique relativement souple, ici en élastomère. Les collerettes 19 à 28 sont relativement flexibles, en raison de la souplesse du matériau dans lequel elles sont faites, de leur épaisseur relativement faible et de l'écart existant entre les collerettes de l'ensemble 17. The tip 12 is made of relatively flexible plastic material, here elastomer. The flanges 19 to 28 are relatively flexible, because of the flexibility of the material in which they are made, their relatively small thickness and the gap between the flanges of the assembly 17.
Du fait du renflement annulaire 35, la collerette 18 est relativement flexible dans sa partie périphérique située au-delà du renflement 35 vers l'extérieur, mais est relativement rigide au niveau du renflement 35.  Because of the annular bulge 35, the flange 18 is relatively flexible in its peripheral portion located beyond the outward bulge 35, but is relatively rigid at the bulge 35.
Etant donné que la collerette 18 est prévue pour être située à la jonction entre le vagin et le col de l'utérus de l'animal, cette conformation particulière de la collerette 18 est favorable à l'étanchéité entre l'embout 12 et le col de l'utérus, et donc aux performances de l'insémination artificielle puisqu'une telle étanchéité évite les pertes de semence par reflux.  Since the collar 18 is intended to be located at the junction between the vagina and the cervix of the animal, this particular conformation of the collar 18 is favorable to the seal between the tip 12 and the collar of the uterus, and therefore the performance of artificial insemination since such a seal avoids losses of semen by reflux.
Comme on le voit bien sur les figures 4 et 5, les collerettes 25 à 28, qui sont les plus proches de l'extrémité distale 13, présentent chacune des encoches 37 s'étendant chacune de l'extrémité libre vers le centre de ces collerettes.  As can be seen in FIGS. 4 and 5, the flanges 25 to 28, which are the closest to the distal end 13, each have notches 37 each extending from the free end towards the center of these flanges. .
Ici, chacune des collerettes 25 à 28 comporte deux encoches 37 diamétralement opposées, dont le fond 38 est relativement proche du fût 30.  Here, each of the flanges 25 to 28 comprises two notches 37 diametrically opposed, whose bottom 38 is relatively close to the shaft 30.
Les encoches 37 permettent aux collerettes 25 à 28 d'être particulièrement flexible et en tout cas plus flexible que les collerettes 19 à 22 qui ne présentent aucune encoche.  The notches 37 allow the flanges 25 to 28 to be particularly flexible and in any case more flexible than the flanges 19 to 22 which have no notch.
Le diamètre plus petit de la portion 32 du fût 30, qui fait que les collerettes 25 à 28 sont relativement longues, contribue également ici à la flexibilité des collerettes 25 à 28.  The smaller diameter of the portion 32 of the barrel 30, which causes the flanges 25 to 28 to be relatively long, also contributes here to the flexibility of the flanges 25 to 28.
Cette flexibilité élevée est favorable à l'insertion de l'embout 12 dans le col de l'utérus.  This high flexibility is favorable for the insertion of the tip 12 into the cervix.
De même le caractère évasé du contour général des collerettes de l'ensemble 17 du côté de l'extrémité distale 13 est favorable à l'insertion de l'embout 12 dans le col de l'utérus.  Similarly, the flared nature of the general outline of the flanges of the assembly 17 on the side of the distal end 13 is favorable to the insertion of the tip 12 in the cervix of the uterus.
La gorge que présente le contour général de l'ensemble 17 dans une position intermédiaire, grâce au diamètre très petit des collerettes 23 et 24, est favorable au maintien en position de l'embout 12. En effet, cette forme correspond bien à la morphologie annelée de l'utérus d'un animal femelle porcin. The groove that presents the general contour of the assembly 17 in an intermediate position, thanks to the very small diameter of the flanges 23 and 24, is favorable to maintaining the position of the endpiece 12. In fact, this shape corresponds well to the ringed morphology of the uterus of a porcine female animal.
Ici, le corps allongé 1 1 est d'une seule pièce avec l'embout 12. Plus précisément, ici l'embout 12 et le corps allongé 1 1 sont en élastomère moulé d'une seule pièce.  Here, the elongate body 1 1 is in one piece with the endpiece 12. More precisely, here the endpiece 12 and the elongate body 1 1 are elastomeric molded in one piece.
Le corps allongé 1 1 est tubulaire avec du côté opposé à l'embout 12 une portion 40 dont la paroi est relativement épaisse et, entre la portion 40 et l'embout 12, une portion 41 dont la paroi est relativement peu épaisse.  The elongate body 1 1 is tubular with the side opposite to the tip 12 a portion 40 whose wall is relatively thick and between the portion 40 and the tip 12, a portion 41 whose wall is relatively thin.
Le conduit 16 interne à la sonde 10 s'étend sur toute sa longueur, entre l'orifice 15 et un orifice situé à l'extrémité opposée de la sonde 10.  The conduit 16 internal to the probe 10 extends over its entire length, between the orifice 15 and an orifice located at the opposite end of the probe 10.
A l'intérieur de l'embout 12, le conduit 16 présente différents changements de diamètres, afin de loger divers éléments complémentaires.  Inside the nozzle 12, the conduit 16 has different diameter changes, to accommodate various complementary elements.
Le sonde 10 est en effet prévue pour faire partie d'un ensemble d'insémination qui comporte, en outre de la sonde 10, un fourreau rigide disposé dans le corps allongé 1 1 et partiellement dans l'embout 12 tandis qu'est prévu entre le fourreau rigide et l'orifice 15 un obturateur comportant un bouchon fait dans une cire qui fond à la température de l'appareil génital d'un animal femelle porcin (environ 37°, cette cire étant semblable à celle utilisée pour former les suppositoires).  The probe 10 is in fact intended to be part of an insemination assembly which comprises, in addition to the probe 10, a rigid sheath disposed in the elongate body 11 and partially in the mouthpiece 12, while between the rigid sheath and the orifice 15 a shutter comprising a plug made in a wax which melts at the temperature of the genital apparatus of a porcine female animal (approximately 37 °, this wax being similar to that used to form the suppositories) .
La portion 41 du corps allongé 1 1 , dont la paroi est relativement peu épaisse, est prévue pour se gonfler à la façon d'un ballon autour du fourreau rigide, par remplissage d'une dose de semence.  The portion 41 of the elongated body 11, whose wall is relatively thin, is designed to inflate like a balloon around the rigid sheath, by filling a dose of seed.
Pour plus de détail sur les éléments de l'ensemble d'insémination autres que la sonde 10, on pourra se reporter à la demande internationale PCT WO 2008/055665.  For more details on the elements of the insemination set other than the probe 10, reference can be made to PCT international application WO 2008/055665.
L'ensemble qui comporte la sonde 10 est prévu pour être posé sur l'animal à l'état rempli, en le faisant progresser dans le vagin de l'animal avec l'embout 12 en premier jusqu'à ce que l'embout 12 se positionne dans le col de l'utérus ainsi qu'expliqué ci-dessus.  The assembly comprising the probe 10 is intended to be placed on the animal in the filled state, by advancing it in the vagina of the animal with the tip 12 first until the tip 12 is positioned in the cervix as explained above.
Au bout d'un certain temps, le bouchon en cire fond et la semence s'écoule de l'ensemble d'insémination par l'orifice 15 de l'embout 12. Une fois que la semence est écoulée, l'ensemble d'insémination est enlevé. La souplesse des collerettes de l'ensemble 17 les plus proches de l'extrémité distale 13 (collerettes 25 à 28) permet une insertion et un retrait aisé de cet ensemble d'insémination. After a while, the wax plug melts and the semen flows from the insemination unit through the orifice 15 of the tip 12. Once the seed has elapsed, the set of insemination is removed. The flexibility of the flanges of the assembly 17 closest to the distal end 13 (flanges 25 to 28) allows easy insertion and removal of this set of insemination.
Dans une variante non illustrée, l'embout 12 fait partie d'une sonde de type différent, avec par exemple le corps allongé 1 1 qui est remplacé par un tube relativement rigide prévu pour être relié, du côté opposé à l'embout, à un sachet dans lequel la semence est conditionnée, par exemple ainsi que décrit dans la demande de brevet européen EP 0 480 700 ; ou encore la sonde fait partie d'un instrument de transfert intra-utérin comportant un cathéter qui est dans la sonde lors de sa pose et qui, une fois l'embout en place dans le col de l'utérus, est sorti de la sonde par l'orifice de l'extrémité distale de l'embout pour progresser dans l'utérus.  In a variant not shown, the tip 12 is part of a different type of probe, with for example the elongate body 11 which is replaced by a relatively rigid tube intended to be connected, on the opposite side to the tip, to a bag in which the seed is packaged, for example as described in the European patent application EP 0 480 700; or the probe is part of an intrauterine transfer instrument with a catheter that is in the probe when it is placed and, once the tip is in place in the cervix, is removed from the probe through the orifice of the distal end of the tip to progress in the uterus.
Dans des variantes non représentées, l'embout 12 est remplacé par un embout comportant un ensemble de collerettes tel que l'ensemble 17, avec la collerette la plus proche de l'extrémité proximale qui comporte elle aussi un renflement configuré pour que cette collerette présente une brusque variation d'épaisseur à la jonction entre le renflement annulaire et la portion périphérique de cette collerette située plus à l'extérieur que le renflement annulaire, mais les collerettes sont agencées différemment, par exemple avec une épaisseur variable entre le fût et l'extrémité libre de la collerette, un nombre de collerettes différent, l'absence d'encoches dans les collerettes les plus proches de l'extrémité distale et/ou une variation des diamètres des différentes collerettes donnant à l'embout un contour général différent, par exemple avec un diamètre des collerettes qui augmente au fur et à mesure que l'on s'éloigne de l'extrémité distale, comme décrit dans la demande internationale PCT WO 2008/055665.  In variants not shown, the tip 12 is replaced by a tip comprising a set of collars such as the assembly 17, with the flange closest to the proximal end which also has a bulge configured so that this collar presents a sudden change in thickness at the junction between the annular bulge and the peripheral portion of this flange located further outside than the annular bulge, but the collars are arranged differently, for example with a variable thickness between the barrel and the free end of the flange, a different number of flanges, the absence of notches in the flanges closest to the distal end and / or a variation of the diameters of the different flanges giving the tip a different general outline, example with a diameter of the flanges which increases as one moves away from the distal end, as described in PCT International Application WO 2008/055665.
Dans d'autres variantes, l'embout est configuré pour un animal d'élevage autre que porcin, par exemple un animal bovin ou caprin.  In other variants, the tip is configured for a farm animal other than swine, for example a bovine or goat animal.
De nombreuses autres variantes sont possibles en fonction des circonstances, et l'on rappelle à cet égard que l'invention ne se limite pas aux exemples décrits et représentés.  Many other variants are possible depending on the circumstances, and it is recalled in this regard that the invention is not limited to the examples described and shown.
