Description

La présente invention est relative à un dispositif d'un type nouveau, destiné à effectuer un prélèvement sanguin, notamment sur un animal. The present invention relates to a device of a new type, intended for taking a blood sample, in particular from an animal.

On sait qu'un éleveur est amené à effectuer périodiquement des prélevements sanguins sur son bétail. Pour cela, il est connu d'utiliser un tube sous vide, fermé par un opercule souple perforable, l'ensemble étant assorti d'un porte-tube, sur lequel l'utilisateur peut adapter une aiguille creuse. L'aiguille étant tout d'abord piquée dans une veine de l'animal, l'opérateur présente le tube à vide, dont il perfore l'opercule sur l'extrémité dépassante de l'aiguille. Sous l'effet du vide, le tube se remplit alors d'une dose de sang, après quoi, l'opérateur retire tube et aiguille. We know that a breeder is required to periodically draw blood samples from his livestock. For this, it is known to use a vacuum tube, closed by a flexible perforable cover, the assembly being accompanied by a tube holder, on which the user can adapt a hollow needle. The needle being first of all stuck in a vein of the animal, the operator presents the vacuum tube, of which it perforates the operculum on the projecting end of the needle. Under the effect of the vacuum, the tube then fills with a dose of blood, after which the operator withdraws the tube and needle.

On sait que les matériels utilisés à ce jour présentent divers inconvénients. Tout d'abord, leur mise en oeuvre est relativement difficile et délicate L'opérateur doit, dans un premier temps, piquer la veine de l'animal, après qui il présente le tube pour l'adapter sur l'aiguille. Pendant ce temps, l'animal manifeste fréquemment des signes d'impatience, qui compliquent l'opération. De toute façon, on constate que les différentes manoeuvres ainsi réalisées ne respectent pas les règles dlaseptie. Il est arrivé que des maladies voient ainsi -transmises d'un animal à l'autre. We know that the materials used to date have various drawbacks. First of all, their implementation is relatively difficult and delicate. The operator must, firstly, prick the vein of the animal, after which he presents the tube to adapt it on the needle. During this time, the animal frequently manifests signs of impatience, which complicate the operation. In any case, it can be seen that the various maneuvers thus carried out do not respect the rules of dlaseptie. It has happened that illnesses are seen thus transmitted from one animal to another.

La présente invention a pour but d'éviter ces inconvénients, en réalisant un dispositif qui assure automatiquement le respect des règles d'aseptie, tout en facilitant considérablement la manoeuvre de lfopérateur dont l'intervention peut être effectuée en un temps très court, presque instantanément. The present invention aims to avoid these drawbacks, by providing a device which automatically ensures compliance with the aseptic rules, while considerably facilitating the maneuver of the operator whose intervention can be carried out in a very short time, almost instantaneously. .

Un dispositif selon l'invention comprend dune part, un tube à vide, fermé par un bouchon perforable souple, d'autre part, une-aiguille creuse pourvue d'une collerette transversale, et enfin, un porte-tube muni d'une pince susceptible de recevoir à la fois l'aiguille et le tube, et il est caractérisé en ce que le bouchon souple du tube comporte un logement borgne, susceptible de recevoir en la pinçant, lzextrémité supérieure de l'ai- guille creuse qui est ainsi rendue solidaire du tube à vide, avant même d'en avoir perforé le bouchon. A device according to the invention comprises on the one hand, a vacuum tube, closed by a flexible perforable plug, on the other hand, a hollow needle provided with a transverse collar, and finally, a tube holder provided with a clamp capable of receiving both the needle and the tube, and it is characterized in that the flexible plug of the tube comprises a blind housing, capable of receiving by pinching it, the upper end of the hollow needle which is thus rendered integral with the vacuum tube, even before having perforated the cap.

Suivant une autre caractéristique de l'invention, la collerette transversale de aiguille est constituée par un sim ple disque. According to another characteristic of the invention, the transverse collar of the needle is constituted by a simple disc.

Suivant une autre caractéristique de l'invention1 le tube à
vide, son bouchon perforable, et l'aiguille pincée dans le logement
borgne de ce bouchon, constituent un ensemble stérile, fabriqué et
livré coiffé d'une gaine qui recouvre l'ensemble de l'aiguille et
le bouchon du tube.
According to another characteristic of the invention1 the tube to
empty, its perforable cap, and the needle pinched in the housing
cap, constitute a sterile assembly, manufactured and
delivered capped with a sheath which covers the entire needle and
the tube plug.

Suivant une autre caractéristique de l'invention, le porte
tube formant pince comporte un épaulement d'extrémité muni d'une
perforation, situé à l'extrémité d'un corps tubulaire dont le dia
mètre intérieur est suffisant pour qu'on puisse y glisser, en le
guidant, le tube à vide fermé par son bouchon.
According to another characteristic of the invention, the door
clamp forming tube has an end shoulder provided with a
perforation, located at the end of a tubular body whose dia
inner meter is enough for you to slide in, by
guiding, the vacuum tube closed by its cap.

Suivant une autre caractéristique de l'invention, le corps
tubulaire de la pince est traversé, près de son extrémité à épaule
ment perforé, par deux ouvertures latérales, dans chacune desquelles
s'engage le bas d'un levier de la pince, ces deux leviers étant arti
culés chacun sur le corps tubulaire, le long duquel ils sont dizad-
tralement opposés, alors que des moyens élastiques les rappellent
dans la position où les becs font saillie à l'intérieur du corpl tu
bullaire, à travers les ouvertures opposées.
According to another characteristic of the invention, the body
tubular clamp is crossed, near its shoulder end
mentally perforated, by two lateral openings, in each of which
engages the bottom of a clamp lever, these two levers being articulated
each abutment on the tubular body, along which they are dizad-
trally opposite, when elastic means recall them
in the position where the beaks protrude inside the corpl tu
bullaire, through the opposite openings.

Le dessin annexé, donné à titre d'exemple non linitatif,per-
mettra de mieux comprendre les caractéristiques de l'invention.
The attached drawing, given by way of non-illustrative example, illustrates
will better understand the features of the invention.

Figure 7 montre la pince retenant l'aiguille, après que l ttilisateur en ait extrait le tube chargé d'un échantillon de sang. Figure 7 shows the forceps holding the needle, after the user has extracted the tube loaded with a blood sample.

Figure 8 montre comment l'opérateur se débarrasse ensuite
de l'aiguille usagée
L'aiguille 1 selon l'invention (figure 1) est oonstituée,à zamanière connue, par un tube capillaire métallique dont les deux ex
trémitéa 2 et 3, sont taillées en biseau, pour faciliter la perfo
ration. L'aiguille 1 selon l'invention comporte une collerette
transversale 4, constituée par un simple disque, par exemple en en matière plastique.
Figure 8 shows how the operator then disposes
used needle
The needle 1 according to the invention (Figure 1) is constituted, with known zamanière, by a metallic capillary tube, the two ex
tr tips 2 and 3, are cut in a bevel, to facilitate the perforation
ration. The needle 1 according to the invention comprises a collar
transverse 4, consisting of a simple disc, for example made of plastic.

La coiffe stérile 5 illustrée sur la figure 2 est une enveloppe de matière plastique comprenant un doigt de gant 6 appelé à ooiffer l'extrémité 2 de l'aiguille 1, puis une embase qui définit deux épaulements intérieur successifs 7 et 8. Le diamètre intérieur de l'épaulement 77 est suffisant pour recevoir la collerette 4 qui y prend appui, tandis que l'extrémité 2 de l'aiguille 1 reste dissimu- lée dans le doigt de gant 6 (figure 4). The sterile cap 5 illustrated in FIG. 2 is a plastic envelope comprising a thermowell 6 called to ooiffer the end 2 of the needle 1, then a base which defines two successive internal shoulders 7 and 8. The internal diameter of the shoulder 77 is sufficient to receive the flange 4 which bears thereon, while the end 2 of the needle 1 remains concealed in the thermowell 6 (FIG. 4).

Le diamètre intérieur de l'épaulement 8 est sensiblement égal au diamètre extérieur 9 d'un bouchon perforable souple 10, qui referme de façon étanche un tube de serre 11 à l'intérieur duquel règne le vide. The internal diameter of the shoulder 8 is substantially equal to the external diameter 9 of a flexible perforable plug 10, which tightly closes a greenhouse tube 11 inside which the vacuum prevails.

Selon l'invention, le bouchon perforable 10 comporte un logement borgne 30 qui débouche vers l'extérieur par une lèvre 31, sus- ceptible de recevoir l'aiguille I en la pinçant, au voisinage de son extrémité supérieure 3. According to the invention, the perforable plug 10 comprises a blind housing 30 which opens outwards via a lip 31, capable of receiving the needle I by pinching it, in the vicinity of its upper end 3.

Lorsque les divers éléments 1, 5, 10 et 11 sont assemblés, ils se présentent à la façon illustrée sur la figure 4, pour constituer un ensemble stérile. L'aiguille 1 est solidaire du bouchon 10 dont la lèvre 31 pince son extrémité supérieure t le vide règne à lBinté- rieur du tube 11 3 la coiffe 5 recouvre l'ensemble de l'aiguille 1, en s'adaptant sur le bouchon 10, ou sur l'extrémité correspondante du tube 11. When the various elements 1, 5, 10 and 11 are assembled, they are presented in the manner illustrated in FIG. 4, to constitute a sterile assembly. The needle 1 is integral with the plug 10, the lip 31 of which clamps its upper end t the vacuum prevails inside the tube 11 3 the cap 5 covers the assembly of the needle 1, by fitting on the plug 10 , or on the corresponding end of the tube 11.

L'ensemble selon l'invention est complété par un portetube formant pince 12, qui peut-#tre réalisé par exemple en matière plastique. Cette pièce comprend un corps tubulaire 13, dont le diamètre intérieur est suffisant pour recevoir en le guidant, l'en- semble du tube 11 et de son bouchon 10. The assembly according to the invention is completed by a tube holder forming a clamp 12, which can be made, for example, of plastics material. This part comprises a tubular body 13, the internal diameter of which is sufficient to receive, by guiding it, the assembly of the tube 11 and of its plug 10.

 son extrémité inférieure, le corps tubulaire 13 est refermé par un épaulement transversal 14 muni, en son centre, d'une perforation 15, dont le diamètre est largement supérieur au diamètre de la tige métallique de l'aiguille 1. L'épaulement 14 a un diamètre correspondant sensiblement à celui de la collerette 4, qu'il reçoit en lui servant de butée. At its lower end, the tubular body 13 is closed by a transverse shoulder 14 provided, in its center, with a perforation 15, the diameter of which is much greater than the diameter of the metal rod of the needle 1. The shoulder 14 has a diameter corresponding substantially to that of the collar 4, which it receives by serving as a stop.

Âu-dessus de l'épaulement 14 le corps tubulaire 13 est traversé par deux ouvertures latérales 16, diamétralement opposées, dans chacune desquelles est engagé le bec 17 d'un levier 18. D3ns sa partie centrale, chaque levier 18 est articulé par un axe 19, sur une chape 20, solidaire de l'extérieur du corpstubulaire g ntgotg ou caoutchouc de compression 21 est prévu entre l'extrémité libre 22 de chaque levier 18 et le corps tubulaire 13
Le bec 17. de chaque levier 18 est découpé suivant une butée transversale 25 suivie par deux rampes obliques 24 et 25 (figure 7), entre lesquelles se trouve défini un cran de retenue 26.
Above the shoulder 14 the tubular body 13 is crossed by two lateral openings 16, diametrically opposite, in each of which is engaged the spout 17 of a lever 18. In its central part, each lever 18 is articulated by an axis 19, on a yoke 20, integral with the outside of the corpstubular g ntgotg or compression rubber 21 is provided between the free end 22 of each lever 18 and the tubular body 13
The spout 17. of each lever 18 is cut along a transverse stop 25 followed by two oblique ramps 24 and 25 (FIG. 7), between which a retaining notch 26 is defined.

Le fonctionnement est le suivant s
Lorsque l'utilisateur se trouve parmi son troupeau, il prélève un ensemble stérile 1., 5, 1D, 11 du type illustré sur la figure 4...
The operation is as follows:
When the user is among his herd, he takes a sterile set 1, 5, 1D, 11 of the type illustrated in Figure 4 ...

Prenant en mains le tube 11 il arrache la coiffe 6.. etla jette, ce qui met à découvert l'aiguille 1 qui reste pincée dans le logement 30 du bouchon 10. Il introduit alors cet ensemble dans le portetube 12, suivant la direction indiquée en figure 5, par la flèche 27.. Taking the tube 11 in his hand, he tears off the cap 6 .. and throws it away, which uncovers the needle 1 which remains pinched in the housing 30 of the plug 10. He then introduces this assembly into the tube holder 12, in the direction indicated in Figure 5, by arrow 27 ..

Dès le début de cette opération, le corps tubulaire 1.3 assure le guidage de l'extrémité du tube 11 et de son bouchon 10 Ainsi, lorsque ltextrémité biseautée 2 de l'aiguille 1 arrive au niveau de l'épaulement 14, elle est automatiquement centrée face à l'orifice 15 quelle traverse sang en toucher les bords, sous l'effet du guidage que continue à assurer le corps tubulaire 15 L'enfoncement s'effectue Jusqu'à la position illustrée sur la figure 5, pour la- quelle la collerette 4 de l'aiguille 1 est en butée sur l'épaule- ment 14, tandis que la face avant du bouchon 10 est en butée sur l'épaulement 23 du bec 17 des leviers 18+ Le bec 17 retient lépau- lement 14~
Cet ensemble illustré sur la figure 5 est prêt à l'emploi, cest-à-dire que l'opérateur saisissant dans sa main la pince 12 et l'arrière du tube 11, peut piquer Aiguille 1 dans la chair de l'animal, et chercher la veine. Dès qu'il l'a trouvée, il lui suffit alors de presser, en les rapprochant les extrémités 22 des leviers lE (figure 6), tout en continuant à appuyer sur l'arrière du tube 11, pour l'enfoncer, comme indiqué par la flèche 28.Ce faisant, lopé- rateur enfonce le tube Il davantage à l'intérieur du corps tubulaire 13, entre les becs écartés 17 des leviers 18. Cette phase provoque l'enfoncement de l'extrémité 3. de l'aiguille 1 dans le bouchon 10, jusqu'à sa complète perforation. Dès que cette perforation est réalisée, le sang de l'animal est attiré par le vide du tube il qui se remplit de sang 29. L'opérateur retire alors de l'animal l'ensemble illustré sur la figure 6.
From the start of this operation, the tubular body 1.3 guides the end of the tube 11 and its stopper 10. Thus, when the bevelled end 2 of the needle 1 arrives at the shoulder 14, it is automatically centered. opposite the orifice 15 which blood crosses it touching the edges, under the effect of the guidance which the tubular body continues to provide 15 The insertion takes place Up to the position illustrated in FIG. 5, for which the flange 4 of the needle 1 is in abutment on the shoulder 14, while the front face of the plug 10 is in abutment on the shoulder 23 of the spout 17 of the levers 18+ The spout 17 retains the shoulder 14 ~
This assembly illustrated in FIG. 5 is ready for use, that is to say that the operator grasping in his hand the clamp 12 and the rear of the tube 11, can prick Needle 1 into the flesh of the animal, and look for the vein. As soon as he has found it, it then suffices to press it, bringing the ends 22 of the levers lE together (FIG. 6), while continuing to press the rear of the tube 11, to push it in, as indicated by the arrow 28. In doing so, the operator pushes the tube II further inside the tubular body 13, between the spouts apart 17 of the levers 18. This phase causes the tip 3 of the needle to sink. 1 in the plug 10, until its complete perforation. As soon as this perforation is carried out, the blood of the animal is attracted by the vacuum of the tube il which fills with blood 29. The operator then removes from the animal the assembly illustrated in FIG. 6.

On voit que la prise de sang proprement dite, y compris la re cherche de la veine, s'effectue en un temps très court, pratiquement en Ull seul geste d'enfoncement. Par ailleurs, toutes les règles d'aseptie sont rigoureusement respectées. It can be seen that the actual blood test, including the search for the vein, takes place in a very short time, practically in a single gesture of penetration. In addition, all the aseptic rules are strictly observed.

Après la prise de sang, il suffit à l'opérateur de saisir l'extrémité arrière du tube 11, et de la tirer, pour extraire le tube hors du corps tubulaire 13 de la pièce 12 (figure 7).. Pendant cette opération, les crans 26 des leviers 18 retiennent la collerette 4 de l'aiguille 1, Si bien qu'en extrayant le tube 11, on l'arrache automatiquement de l'aiguille 1. les caractéristiques auto-cicatrisantes de la matière (caoutchouc ou matière plastique) du bouchon 10 provoquent automatiquement sa fermeture. Le tube 11 est ainsi chargé de façon stérile avec l'échantillon sanguin 29 (figure 7). After the blood test, the operator need only grasp the rear end of the tube 11, and pull it, to extract the tube from the tubular body 13 of the part 12 (FIG. 7). During this operation, the notches 26 of the levers 18 retain the flange 4 of the needle 1, so that by extracting the tube 11, it is automatically torn from the needle 1. the self-healing characteristics of the material (rubber or plastic ) of the plug 10 automatically cause it to close. The tube 11 is thus loaded in a sterile manner with the blood sample 29 (FIG. 7).

Pour éliminer l'aiguille 1 et la jeter, il suffit alors à l'opérateur, de renverser le porte-tube 12 en pressant les extrémités 22 des leviers 18, à l'encontre des ressorts 21. Les crans 26 s'écartent alors l'un de l'autre, et l'aiguille 1 tombe delle-même.  To eliminate the needle 1 and throw it away, the operator just has to reverse the tube holder 12 by pressing the ends 22 of the levers 18, against the springs 21. The notches 26 then move apart. from each other, and needle 1 falls by itself.

Le porte-tube 12 est alors prêt à recevoir une nouvelle aiguille 1, pour recommencer un nouveau cycle dont on voit qu'il respecte parfaitement les règles d'aseptie.  The tube holder 12 is then ready to receive a new needle 1, to start a new cycle which we see that it perfectly respects the aseptic rules.
