Description
Paillette pour la conservation d'une dose prédéterminée de substance à base liquide, notamment de la semence animale Paillette for preserving a predetermined dose of liquid-based substance, especially animal semen
pure ou diluée L'invention a trait d'une manière générale à la conservation d'une dose prédéterminée de substance à base liquide, notamment de la semence animale pure ou diluée ; et plus particulièrement aux paillettes pour effectuer une telle conservation. The invention relates generally to the preservation of a predetermined dose of liquid-based substance, especially pure or diluted animal semen; and more particularly to flakes to effect such preservation.
On sait qu'une telle paillette comporte un tube et un bouchon disposé dans le tube. Le bouchon est habituellement du type tripartite décrit à l'origine dans le brevet français 995.878, correspondant au brevet britannique 669,265, c'est-à-dire formé par deux tampons en substance fibreuse enserrant une poudre susceptible de se transformer au contact d'un liquide en une pâte ou gel imperméable adhérant à la paroi du tube pour que le bouchon soit étanche aux liquides. It is known that such straw comprises a tube and a plug disposed in the tube. The plug is usually of the tripartite type originally described in French Patent 995,878, corresponding to British Patent 669,265, that is to say formed by two pads of fibrous substance enclosing a powder capable of being transformed in contact with a liquid into an impermeable paste or gel adhering to the wall of the tube so that the cap is liquid-tight.
Des bouchons semblables mais perfectionnés sont décrits par les demandes de brevet français 2 824 255 et 2 824 256. Similar but improved stoppers are described by French patent applications 2,824,255 and 2,824,256.
On connaît également des bouchons d'un autre type, par exemple un bouchon fait d'un cylindre monobloc de matière microporeuse hydrophobe décrit par la demande de brevet européen 0 873 726 ou un bouchon fait d'un cylindre monobloc de matière microporeuse auto-scellante fritté décrit par la demande PCT WO 2010/070533. Also known are plugs of another type, for example a plug made of a monobloc cylinder of hydrophobic microporous material described by the European patent application 0 873 726 or a plug made of a monoblock cylinder of self-sealing microporous material sintered described by PCT application WO 2010/070533.
A l'état initial, le bouchon est disposé au voisinage de l'une des extrémités du tube et il est prévu qu'à l'état rempli, la dose de substance liquide qui doit être conservée dans la paillette soit disposée entre le bouchon et l'autre extrémité du tube (extrémité la plus éloignée du bouchon). In the initial state, the stopper is disposed in the vicinity of one of the ends of the tube and it is expected that in the filled state, the dose of liquid substance that must be stored in the straw is disposed between the stopper and the other end of the tube (end farthest from the plug).
Pour remplir la paillette, l'extrémité la plus proche du bouchon est mise en communication avec une source de vide tandis que l'extrémité la plus éloignée du tube est mise en communication avec un récipient contenant la substance à introduire dans la paillette. L'air initialement contenu entre le bouchon et l'extrémité la plus éloignée du tube est aspiré au travers du bouchon tandis que la substance progresse dans le tube jusqu'à ce qu'elle rencontre le bouchon. To fill the straw, the end closest to the plug is placed in communication with a source of vacuum while the end farthest from the tube is placed in communication with a container containing the substance to be introduced into the straw. The air initially contained between the plug and the furthest end of the tube is sucked through the plug as the substance progresses through the tube until it meets the plug.
Le cas échéant, la paillette est soudée au voisinage de l'une ou de ses deux extrémités et est stockée au froid. If necessary, the straw is welded in the vicinity of one or both ends and is stored cold.
Pour vider la paillette, le cas échéant après découpage des portions d'extrémité soudées et décongélation, on fait pénétrer dans le tube par l'extrémité la plus proche du bouchon une tige qui vient porter contre le bouchon. Avec cette tige, on fait coulisser le bouchon à la façon d'un piston vers l'extrémité la plus éloignée du bouchon, ce qui provoque l'expulsion de la dose de substance qui avait été introduite dans la paillette. To empty the flake, if necessary after cutting the welded end portions and defrosting, is introduced into the tube through the end nearest the plug a rod that bears against the plug. With this rod, the plug is slid in the manner of a piston towards the end farthest from the plug, which causes the expulsion of the dose of substance that had been introduced into the straw.
L'invention vise à fournir une telle paillette capable d'être discriminée d'autres paillettes. The invention aims to provide such a straw capable of being discriminated other flakes.
L'invention propose à cet effet une paillette pour la conservation d'une dose prédéterminée de substance à base liquide, comportant un tube et un bouchon perméable aux gaz et étanche aux liquides, lequel bouchon est disposé dans le tube au voisinage d'une extrémité, caractérisé en ce que ledit bouchon comporte un composant magnétique configuré pour qu'un aimant, placé à fleur du tube au droit du bouchon, puis déplacé sur une surface horizontale, est alors suivi par la paillette. The invention proposes for this purpose a straw for the preservation of a predetermined dose of liquid-based substance, comprising a tube and a gas-permeable and liquid-tight plug, which plug is placed in the tube in the vicinity of one end. , characterized in that said cap comprises a magnetic component configured so that a magnet placed flush with the tube at the cap, and then moved on a horizontal surface, is then followed by the straw.
Au contraire, une paillette conventionnelle, dont le bouchon ne comporte aucun composant magnétique, sera insensible à l'aimant, et restera donc en place lorsque l'aimant est déplacé. On the contrary, a conventional flake, whose plug has no magnetic component, will be insensitive to the magnet, and will remain in place when the magnet is moved.
On observera qu'il est relativement simple et économique de munir le bouchon d'une paillette d'un composant magnétique, et qu'un simple aimant suffit pour reconnaître si une paillette dont on est en présence est une paillette ordinaire ou une paillette prévue pour être discriminée. It will be observed that it is relatively simple and economical to provide the cap with a flake of a magnetic component, and that a simple magnet is sufficient to recognize if a flake that is present is an ordinary flake or a flake provided for to be discriminated against.
Selon des caractéristiques préférées comme étant particulièrement simples, commodes et économiques à mettre en œuvre : According to preferred features as being particularly simple, convenient and economical to implement:
- ledit bouchon est formé par deux tampons en substance fibreuse enserrant une poudre susceptible de se transformer au contact d'un liquide en une pâte ou gel imperméable adhérant à la paroi du tube pour que le bouchon soit étanche aux liquides, avec ledit composant magnétique qui comporte ladite poudre ; said stopper is formed by two pads of fibrous substance enclosing a powder capable of being transformed on contact with a liquid into an impermeable paste or gel adhering to the wall of the tube so that the stopper is liquid-tight, with said magnetic component which comprises said powder;

L'invention vise également un procédé de reconnaissance d'une paillette, caractérisé en ce qu'il comporte l'étape de sélectionner cette paillette comme conforme à la paillette exposée ci-dessus, l'étape de placer ladite paillette sur une surface horizontale, l'étape de placer sur ladite surface un aimant à fleur du tube au droit du bouchon, et l'étape de déplacer l'aimant sur ladite surface en observant si ladite paillette suit ou non l'aimant. The invention also relates to a method of recognizing a straw, characterized in that it comprises the step of selecting this straw as in accordance with the straw discussed above, the step of placing said straw on a horizontal surface, the step of placing on said surface a magnet flush with the tube to the right of the plug, and the step of moving the magnet on said surface by observing whether or not said flake follows the magnet.
L'exposé de l'invention sera maintenant poursuivi par la description d'un exemple de réalisation, donnée ci-après à titre illustratif et non limitatif, en référence aux dessins annexés, sur lesquels : The description of the invention will now be continued by the description of an exemplary embodiment, given below by way of illustration and without limitation, with reference to the appended drawings, in which:
- la figure 1 est une vue schématique en coupe longitudinale d'une paillette selon l'invention ; et - Figure 1 is a schematic longitudinal sectional view of a straw according to the invention; and
- la figure 2 illustre de façon schématique le comportement de la paillette selon l'invention lorsqu'un aimant placé à proximité du bouchon est déplacé. La paillette 10 illustrée sur la figure 1 comporte un tube 1 1 et un bouchon 12. - Figure 2 schematically illustrates the behavior of the straw according to the invention when a magnet placed near the plug is moved. The straw 10 illustrated in FIG. 1 comprises a tube 11 and a plug 12.
Le tube 1 1 est classiquement en matière plastique extrudée, avec un diamètre interne qui est par exemple de 1 ,6 ou de 2,5 mm et une longueur de l'ordre de 133 mm. The tube 1 1 is conventionally extruded plastic, with an internal diameter which is for example 1, 6 or 2.5 mm and a length of the order of 133 mm.
Le bouchon 12 est du type tripartite, c'est-à-dire formé par deux tampons 13 et 14 d'une substance fibreuse enserrant une poudre 15 susceptible de se transformer au contact d'un liquide en une pâte ou gel imperméable adhérant à la paroi du tube pour que le bouchon soit étanche aux liquides. The plug 12 is of the tripartite type, that is to say formed by two buffers 13 and 14 of a fibrous substance enclosing a powder 15 capable of being transformed in contact with a liquid into an impermeable paste or gel adhering to the wall of the tube so that the cap is liquid tight.
A l'état initial, illustré sur la figure 1 , le bouchon 12 est disposé au voisinage de l'extrémité 16 du tube 1 1 et il est prévu qu'à l'état rempli, la dose de substance liquide qui doit être conservée dans la paillette 10 soit disposée entre le bouchon 12 et l'extrémité 17 du tube 1 1 la plus éloignée du bouchon 12. In the initial state, illustrated in Figure 1, the plug 12 is disposed adjacent the end 16 of the tube 1 1 and it is expected that in the filled state, the dose of liquid substance to be stored in the flake 10 is arranged between the plug 12 and the end 17 of the tube 1 1 furthest from the plug 12.
Pour remplir la paillette 10, l'extrémité 16 est mise en communication avec une source de vide tandis que l'extrémité 17 est mise en communication avec un récipient contenant la substance à introduire dans la paillette. To fill the straw 10, the end 16 is placed in communication with a source of vacuum while the end 17 is placed in communication with a container containing the substance to be introduced into the straw.
L'air initialement contenu entre le bouchon 12 et l'extrémité 17 est aspiré au travers du bouchon tandis que la substance progresse dans le tube jusqu'à ce qu'elle rencontre le bouchon 12, par l'extrémité 18 de celui-ci tournée vers l'extrémité 17 du tube 1 1 , c'est-à-dire l'extrémité du bouchon 12 que l'on voit à droite sur la figure 1 . The air initially contained between the plug 12 and the end 17 is sucked through the plug while the substance progresses in the tube until it meets the plug 12, by the end 18 of it turned towards the end 17 of the tube 1 1, that is to say the end of the plug 12 that is seen on the right in FIG.
Le cas échéant, la paillette est soudée au voisinage de l'une ou de ses deux extrémités 16 et 17 et est stockée au froid. If necessary, the straw is welded in the vicinity of one or both ends 16 and 17 and is stored cold.
Pour vider la paillette 10, le cas échéant après découpage des portions d'extrémité soudées et décongélation, on fait pénétrer dans le tube 1 1 une tige qui vient porter contre l'extrémité 19 du bouchon 12 (extrémité située du côté opposé à l'extrémité 18). To empty the flake 10, if necessary after cutting the welded end portions and thawing, is introduced into the tube 1 1 a rod that bears against the end 19 of the plug 12 (end located on the side opposite the end 18).
Avec cette tige, on fait coulisser le bouchon 12 à la façon d'un piston vers l'extrémité 17 ou l'extrémité correspondante après découpe de la portion soudée, ce qui provoque l'expulsion de la dose de substance qui avait été introduite dans la paillette. With this rod, the plug 12 is slid in the manner of a piston towards the end 17 or the corresponding end after cutting the portion welded, causing the expulsion of the dose of substance that had been introduced into the straw.
Pour permettre de discriminer la paillette 10 d'autres paillettes, la poudre 15 n'est pas uniquement formée par de la poudre en matière polymérisant au contact de l'eau, mais comporte également de la poudre de ferrite Fe04. In order to make it possible to discriminate the flake 10 from other flakes, the powder 15 is not only formed by the powder of polymerizing material in contact with water, but also comprises ferrite powder FeO 4 .
Ainsi, la poudre 15 forme un composant magnétique. Thus, the powder forms a magnetic component.
Dans l'exemple illustré, la poudre 15 comporte 20% en volume de poudre de ferrite Fe04. In the example illustrated, the powder 15 comprises 20% by volume of ferrite Fe0 4 powder.
Une plage convenant à la mise en œuvre de l'invention est de 15% à A range suitable for the implementation of the invention is 15% to
25% en volume de poudre de ferrite Fe04. 25% by volume ferrite powder FeO 4 .
Pour maintenir de bonnes conditions de fabrication du bouchon 12, la poudre de ferrite Fe04 a la même granulométrie que le reste de la poudre 15, de sorte que l'ensemble de celle-ci est homogène. To maintain good manufacturing conditions of the plug 12, ferrite powder Fe0 4 has the same particle size as the rest of the powder 15, so that the whole of it is homogeneous.
Dans l'exemple illustré, la poudre 15 est formée exclusivement par la poudre de ferrite Fe04 et par de la poudre de matière polymérisant au contact de l'eau. In the example illustrated, the powder 15 is formed exclusively by FeO 4 ferrite powder and by powder of polymerizing material in contact with water.
Ici, la poudre de matière polymérisant au contact de l'eau est de l'alginate. Here, the polymerizing material powder in contact with water is alginate.
La figure 2 montre en trait plein la paillette 10 posée sur une surface horizontale 20 en train de suivre un aimant 21 qui est déplacé sur la surface horizontale 20, ainsi que montré par la flèche 22. FIG. 2 shows in full line the straw 10 placed on a horizontal surface 20 in the process of following a magnet 21 which is displaced on the horizontal surface 20, as shown by the arrow 22.
La figure 2 montre également, en trait interrompu, la position qu'avaient initialement sur la surface 20, la paillette 10 et l'aimant 21 . FIG. 2 also shows, in dashed line, the position which the surface 20, the straw 10 and the magnet 21 had initially.
Alors que la paillette était sur la surface 20 dans la position montrée en trait interrompu, l'aimant 21 a été placé à fleur du tube 1 1 au droit du bouchon 12. Ensuite, l'aimant 21 a été déplacé comme montré par la flèche 22. While the flake was on the surface 20 in the position shown in broken lines, the magnet 21 was placed flush with the tube 1 1 to the right of the plug 12. Then, the magnet 21 was moved as shown by the arrow 22.
Du fait que le bouchon 12 contient le composant magnétique formé par la poudre 15, lorsque l'aimant 21 est déplacé, la paillette 10 suit l'aimant 21 . Because the plug 12 contains the magnetic component formed by the powder 15, when the magnet 21 is moved, the straw 10 follows the magnet 21.
II est ainsi possible de reconnaître si la paillette 10 a ou non été prévue pour être discriminée. Une paillette conventionnelle, dont le bouchon 12 ne comporte aucun composant magnétique, ne suivra pas l'aimant 21 lorsqu'il aura été placé à fleur du tube au droit du bouchon. It is thus possible to recognize whether or not the straw 10 has been provided to be discriminated. A conventional flake, the plug 12 has no magnetic component, will not follow the magnet 21 when it has been placed flush with the tube to the right of the cap.
On notera que si la poudre de ferrite FeO4 était remplacée par de la limaille de fer, la poudre 15 contiendrait une quantité de limaille de fer insuffisante pour que la paillette 10 suive l'aimant 21 . Note that if the FeO 4 ferrite powder was replaced by iron filings, the powder 15 would contain a quantity of iron filings insufficient for the flake 10 to follow the magnet 21.
Pour ce faire, un composant magnétique est nécessaire dans le bouchon 12. To do this, a magnetic component is required in the plug 12.
La reconnaissance de la paillette 10 peut s'effectuer aussi bien à l'état initial de la paillette 10 (vide) qu'à l'état rempli de la dose de substance liquide à conserver. The recognition of the flake 10 can be carried out both in the initial state of the flake 10 (empty) and in the filled state of the dose of liquid substance to be preserved.
Il est également possible de reconnaître si la paillette est prévue pour être discriminée en plaçant une boussole à proximité du bouchon 12. Si l'aiguille de la boussole se dirige vers le bouchon 12, c'est que celui-ci comporte un composant magnétique. It is also possible to recognize whether the straw is intended to be discriminated by placing a compass near the plug 12. If the compass needle is moving towards the plug 12, it is that it comprises a magnetic component.
Dans des variantes non illustrées, le composant magnétique est différent de la poudre 15, par exemple un fil magnétique associé au bouchon 12 ou à un bouchon de type différent, par exemple un bouchon fait d'un cylindre monobloc tel que décrit dans la demande de brevet européen 0 873 726 ou dans la demande PCT WO 2010/070533. In non-illustrated variants, the magnetic component is different from the powder 15, for example a magnetic wire associated with the plug 12 or with a plug of different type, for example a plug made of a one-piece cylinder as described in the application for European Patent 0 873 726 or in PCT application WO 2010/070533.
L'association d'un fil magnétique au bouchon 12 est effectué par exemple, dans le cas où le tampon 13 ou le tampon 14 est une tresse faite de fils de substance fibreuse, en incorporant le fil magnétique dans la tresse. Par exemple, le fil magnétique est tressé avec les fils de substance fibreuse. The association of a magnetic wire with the plug 12 is performed for example, in the case where the pad 13 or the pad 14 is a braid made of fibrous material son, by incorporating the magnetic wire in the braid. For example, the magnetic thread is braided with the fibrous material threads.
On peut également associer plusieurs fils magnétiques au bouchon It is also possible to associate several magnetic threads with the stopper
12. 12.
Dans une autre variante, le composant magnétique est formé à la fois par la poudre 15 et par le fil magnétique associé au bouchon 12. In another variant, the magnetic component is formed by both the powder 15 and the magnetic wire associated with the plug 12.
De nombreuses autres variantes sont possibles en fonction de 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 circumstances, and it is recalled in this regard that the invention is not limited to the examples described and shown.
