Abstract

A veterinary instrument is closed and sealed in a sterile manner by a cap (4) formed by a lower sleeve tube (7) and an upper part (8). The upper part (8) forms a single body with the lower sleeve tube (7), so that the cap (4) can be moulded in a single piece. The upper part (8) is separated from the lower sleeve tube (7) by an annular notch. The upper edge (10) of the lower sleeve tube (7) forms an annular opening (12) through which the cannula (3) emerges when the upper part (8) is broken with the thumb and removed. <IMAGE>

Description

La présente invention est relative à un instrument vétérinaire pour délivrer une composition médicamenteuse, comprenant :

  • un récipient pour la composition médicamenteuse;
  • une canule allongée qui s'étend à partir du récipient en formant une seule pièce avec celui-ci,
  • un capuchon tubulaire amovible destiné à recouvrir la canule, constitué d'un manchon inférieur et d'une coiffe supérieure, le manchon inférieur étant d'une longueur plus courte que la canule, en s'étendant depuis le récipient le long d'une portion de la longueur de la canule et en aboutissant à une extrémité externe présentant avec la canule un interstice annulaire dimensionné pour empêcher le manchon inférieur de pénétrer à l'intérieur du canal de tette de façon que seule la partie externe de la canule puisse être insérée dans le canal de tette lorsque la coiffe supérieure est détachée du manchon inférieur et le manchon inférieur fixé par rapport à la canule.
The present invention relates to a veterinary instrument for delivering a medicinal composition, comprising:
  • a container for the drug composition;
  • an elongated cannula which extends from the container in a single piece with the latter,
  • a removable tubular cap intended to cover the cannula, consisting of a lower sleeve and an upper cap, the lower sleeve being of a shorter length than the cannula, extending from the container along a portion of the length of the cannula and ending at an external end having with the cannula an annular gap dimensioned to prevent the lower sleeve from penetrating inside the teat canal so that only the external part of the cannula can be inserted into the tette channel when the upper cap is detached from the lower sleeve and the lower sleeve fixed relative to the cannula.

Lors d'un tel traitement, il est souvent utile de n'introduire la canule que sur une portion de longueur dans le canal de tette, de manière à pouvoir déposer la composition médicamenteuse directement à l'intérieur du canal de tette. La longueur de la canule pouvant être logée à l'intérieur du canal de tette correspond à la dimension de l'ouverture du canal de tette.During such treatment, it is often useful to introduce the cannula only over a portion of the length into the teat canal, so that the drug composition can be deposited directly inside the teat canal. The length of the cannula which can be accommodated inside the teat channel corresponds to the dimension of the opening of the teat channel.

Par le document WO90/07913, on connaît déjà un capuchon perfectionné destiné à recouvrir la canule d'un instrument vétérinaire approprié au traitement médical d'une inflammation du pis d'une vache. L'instrument comprend : un récipient destiné à contenir une composition médicamenteuse liquide ou visqueuse, une canule allongée s'étendant à partir du récipient et formant corps avec lui et un capuchon tubulaire constitué de deux parties qui recouvrent la canule et peut être détachée en deux parties. Le capuchon tubulaire comprend en effet un manchon inférieur constitué d'une collerette d'entrée amovible qui protège la canule et une coiffe supérieure gui est fixée rigidement au manchon inférieur et recouvre l'extrémitré libre de la canule.Document WO90 / 07913 already discloses an improved cap intended to cover the cannula with a veterinary instrument suitable for the medical treatment of an inflammation of the udder of a cow. The instrument includes: a container for containing a liquid or viscous drug composition, an elongated cannula extending from the container and forming a body with it, and a tubular cap made up of two parts which cover the cannula and can be detached in two parts. The tubular cap indeed comprises a lower sleeve constituted by a removable entry flange which protects the cannula and an upper cap which is rigidly fixed to the lower sleeve and covers the free end of the cannula.

Le manchon a une longueur plus courte que la canule et s'étend seulement sur une portion de longueur de la canule. Le manchon a une extrémité supérieure présentant une paroi d'extrémité annulaire sensiblement plane, à travers de laquelle la tête de la canule peut être introduite dans le pis de la vache par le canal de tette lorsque la coiffe est détachée du manchon inférieur.The sleeve is shorter in length than the cannula and extends only a portion of the length of the cannula. The sleeve has an upper end having a substantially planar annular end wall, through which the cannula head can be introduced into the udder of the cow through the udder channel when the cap is detached from the lower sleeve.

Le moulage du capuchon constitué de deux pièces est coûteux, parce qu'il exige non seulement l'acquisition de deux matrices différentes et la mise en oeuvre de deux fabrications différentes mais aussi une main d'oeuvre intensive puisqu'il faut monter deux pièces différentes.The molding of the cap consisting of two parts is expensive, because it requires not only the acquisition of two different dies and the implementation of two different manufacturing but also an intensive labor since it is necessary to mount two different parts .

En outre, l'extrémité plane du manchon offre une étanchéité insuffisante et l'inconvénient que des souillures et des sécrétions peuvent être repoussées dans le canal de tette et retarder la guérison de l'infection du pis de la vache.In addition, the flat end of the sleeve offers insufficient sealing and the disadvantage that stains and secretions can be pushed back into the uterus channel and delay the healing of the cow's udder infection.

La paroi d'extrémité annulaire plane présente aussi l'inconvénient de créer une étanchéité insuffisante tout autour de la périphérie du bord supérieur du manchon inférieur lorsque celui-ci est appliqué contre le canal de tette du pis de la vache.The flat annular end wall also has the drawback of creating an insufficient seal all around the periphery of the upper edge of the lower sleeve when the latter is applied against the udder channel of the cow's udder.

Lors de l'injection du médicament, une fraction de la quantité injectée s'échappe de l'instrument le long de la zone de contact du manchon inférieur contre la tette.When injecting the drug, a fraction of the amount injected escapes from the instrument along the contact area of the lower sleeve against the teat.

La présente invention vise à remédier aux inconvénients susdits et propose un système de capuchon qui soit détachable de la canule dans sa totalité ou en partie seulement. Elle concerne un instrument vétérinaire pour délivrer une composition médicamenteuse destinée au traitement médical ou vétérinaire d'une inflammation du pis d'une vache, d'une chèvre ou d'une brebis, comprenant :

  • un récipient pour la composition médicamenteuse,
  • une canule allongée gui s'étend à partir du récipient et formant corps avec celui-ci, ladite canule présentant une extrémité effilée que l'on doit glisser dans le canal de tette et la longueur de la canule étant telle que lorsque la canule est insérée complètement dans le canal de tette, on puisse doser directement la composition médicamenteuse dans le pis; et
  • un capuchon tubulaire amovible destiné à recouvrir la canule, constitué d'un manchon inférieur et d'une coiffe supérieure, le manchon inférieur étant plus court que la canule, en s'étendant depuis le récipient le long d'une portion de longueur de la canule et en aboutissant à une extrémité externe présentant avec la canule un interstice annulaire dimensionné pour empêcher le manchon inférieur d'entrer à l'intérieur du canal de tette, de façon que seule la partie externe de la canule puisse être insérée dans le canal de tette, lorsque la coiffe supérieure est détachée du manchon inférieur et le manchon inférieur fixé par rapport à la canule.
The present invention aims to remedy the above drawbacks and proposes a cap system which is detachable from the cannula in whole or in part only. It relates to a veterinary instrument for delivering a medicinal composition intended for the medical or veterinary treatment of an inflammation of the udder of a cow, a goat or a sheep, comprising:
  • a container for the drug composition,
  • an elongated cannula which extends from the container and forms a body therewith, said cannula having a tapered end which must be slid into the teat channel and the length of the cannula being such that when the cannula is inserted completely in the tette canal, the drug composition can be directly dosed into the udder; and
  • a removable tubular cap intended to cover the cannula, consisting of a lower sleeve and an upper cap, the lower sleeve being shorter than the cannula, extending from the container along a length portion of the cannula and terminating at an outer end having with the cannula an annular gap sized to prevent the lower sleeve from entering the inside the teat channel, so that only the outer part of the cannula can be inserted into the teat canal, when the upper cap is detached from the lower sleeve and the lower sleeve fixed relative to the cannula.

L'instrument est caractérisé en ce que la partie supérieure fait corps avec le manchon inférieur, de manière à pouvoir être monté en une seule pièce et la coiffe supérieure est séparée du manchon inférieur par un interstice annulaire et le bord d'extrémité du manchon inférieur forme une ouverture annulaire au travers de laquelle émerge l'extrémité de la canule, lorsque la coiffe supérieure, destinée à recouvrir l'extrémité de la canule, est brisée à l'aide du pouce et éliminée.The instrument is characterized in that the upper part is integral with the lower sleeve, so that it can be assembled in one piece and the upper cap is separated from the lower sleeve by an annular gap and the end edge of the lower sleeve. forms an annular opening through which the end of the cannula emerges, when the upper cap, intended to cover the end of the cannula, is broken with the thumb and eliminated.

Suivant une particularité de l'invention, la coiffe supérieure du capuchon de la canule peut être brisée à hauteur d'une entaille annulaire gui sépare la coiffe supérieure du manchon.According to a feature of the invention, the upper cap of the cap of the cannula can be broken up to an annular notch which separates the upper cap from the sleeve.

Dans une forme de réalisation particulière, la paroi intérieure du manchon inférieur présente des saillies dirigées vers l'axe central du manchon inférieur, pour maintenir au milieu la canule plutôt flexible.In a particular embodiment, the inner wall of the lower sleeve has projections directed towards the central axis of the lower sleeve, to keep the rather flexible cannula in the middle.

Dans un développement ultérieur, l'orifice annulaire présente des bords supérieurs dont l'épaisseur réalise une zone d'étanchéité à l'air et à l'eau autour du point d'injection du canal de tette du pis, lorsque la composition médicamenteuse est déposée dans le canal de tette.In a further development, the annular orifice has upper edges, the thickness of which provides an air and water tightness zone around the injection point of the udder udder channel, when the drug composition is deposited in the tette channel.

En outre, la dimension du bord supérieur de la périphérie du manchon inférieur est choisie en fonction de la limite d'élasticité biomécanique de la peau et de la chair de la tette du pis.In addition, the dimension of the upper edge of the periphery of the lower sleeve is chosen as a function of the biomechanical elastic limit of the skin and the flesh of the udder tette.

Ces caractéristiques et autres particularités de l'invention sont exposées plus en détail dans la description suivante gui fait référence aux dessins ci-joints dans lesquels :

Dans ces figures, les mêmes signes de référence désignent des éléments identiques ou analogues.In these figures, the same reference signs designate identical or analogous elements.

Comme illustré dans la figure 1, l'instrument vétérinaire 1 selon l'invention, comprend :

  • un récipient 2 rempli d'une quantité déterminée de composition médicamenteuse;
  • une canule allongée gui s'étend à partir du récipient 2 en formant une seule pièce avec celui-ci, et un capuchon formé d'une seule pièce susceptible d'être brisée et qui couvre la canule sur toute la longueur.
As illustrated in FIG. 1, the veterinary instrument 1 according to the invention, comprises:
  • a container 2 filled with a determined quantity of medicinal composition;
  • an elongated cannula mistletoe extends from the container 2 in a single piece with the latter, and a cap formed in one piece capable of being broken and which covers the cannula over the entire length.

La canule 3 possède une extrémité effilée qu'il faut introduire par coulissement dans le canal de tette 5 du pis. La longueur de la canule est telle que, lorsque la canule 3 est introduite entièrement dans le canal de tette 5, la composition médicamenteuse puisse être injectée directement dans le pis 6 (figure 8).The cannula 3 has a tapered end which must be inserted by sliding into the udder channel 5 of the udder. The length of the cannula is such that, when the cannula 3 is fully introduced into the tette channel 5, the composition drug can be injected directly into the udder 6 (Figure 8).

L'extrémité libre de la canule 3 est obturée au moyen d'un capuchon 4 susceptible d'être brisé, qui couvre la canule 3 sur toute la longueur.The free end of the cannula 3 is closed by means of a cap 4 capable of being broken, which covers the cannula 3 over the entire length.

Ce capuchon brisable 4 est moulé en une seule pièce, mais elle comporte deux parties : un manchon 7 qui est monté amoviblement sur la canule 3 et une partie supérieure 8 gui fait partie du manchon 7 et couvre l'extrémité libre de la canule 3. Le manchon 7 est plus court que la canule 3. La partie supérieure 8 est séparée en partie du manchon par une entaille annulaire 9.This breakable cap 4 is molded in one piece, but it has two parts: a sleeve 7 which is removably mounted on the cannula 3 and an upper part 8 which forms part of the sleeve 7 and covers the free end of the cannula 3. The sleeve 7 is shorter than the cannula 3. The upper part 8 is partially separated from the sleeve by an annular notch 9.

Lorsqu'on détache le capuchon 4, on libère la canule sur toute la longueur et on peut ainsi introduire celle-ci sur toute la longueur dans le canal de tette du pis.When the cap 4 is detached, the cannula is released over the entire length and it can thus be introduced over the entire length into the udder teat channel.

Par contre, lorsqu'on brise la partie supérieure 8 du capuchon 4, gui est monté sur la canule 3, on ne libère qu'une partie de la canule 3. L'extrémité libre de la canule émerge du bord supérieur 10 du manchon 7. Seule l'extrémité de la canule 3 est disponible pour être insérée dans le canal de tette 5. La longueur qui peut être introduite dans la tette 11 correspond environ à la dimension de l'orifice du canal de tette 5.On the other hand, when the upper part 8 of the cap 4 is broken, mistletoe is mounted on the cannula 3, only part of the cannula is released. The free end of the cannula emerges from the upper edge 10 of the sleeve 7 Only the end of the cannula 3 is available to be inserted into the tette channel 5. The length which can be introduced into the tette 11 corresponds approximately to the dimension of the orifice of the tette channel 5.

En brisant la partie supérieure 8 du capuchon 4, on forme une ouverture annulaire 12 autour de la dernière partie de la canule 3 et du capuchon 4.By breaking the upper part 8 of the cap 4, an annular opening 12 is formed around the last part of the cannula 3 and of the cap 4.

Cette ouverture annulaire 12 offre deux avantages importants. D'abord, cette ouverture offre l'avantage que des impuretés, en particulier des sécrétions ou des souillures, gui se trouvent au voisinage de l'orifice du canal de tette 5 sur le côté extérieur de la mamelle, peuvent être interceptées dans ladite ouverture, lorsque la dernière portion de longueur de la canule 3 est introduite dans le canal de tette, auquel cas tout risque d'introduire des souillures dans la tette disparaît.This annular opening 12 offers two important advantages. First, this opening has the advantage that impurities, in particular secretions or stains, which are located in the vicinity of the orifice of the tette channel 5 on the outside of the udder, can be intercepted in said opening. , when the last portion of length of the cannula 3 is introduced into the tette channel, in which case any risk of introducing stains into the tette disappears.

L'ouverture annulaire 12 offre ensuite l'avantage de former avec la tette une zone de contact étanche à l'eau sur tout le pourtour du bord supérieur 10 du capuchon 4, au voisinage du point d'injection dans le pis, grâce auquel on évite une fuite de composition médicamenteuse vers l'extérieur pendant l'injection de la composition médicamenteuse.The annular opening 12 then offers the advantage of forming with the tette a watertight contact zone around the entire periphery of the upper edge 10 of the cap 4, in the vicinity of the injection point in the udder, by which prevents leakage of the drug composition to the outside during the injection of the drug composition.

Comme illustré dans la figure 8, le bord arrondi 10 du capuchon 4 s'enfonce dans la chair qui entoure la tette 11 jusqu'à une profondeur suffisante pour obtenir une étanchéité suffisante à l'air.As illustrated in FIG. 8, the rounded edge 10 of the cap 4 is inserted into the flesh which surrounds the head 11 to a depth sufficient to obtain a sufficient airtightness.

La dimension du contour du bord supérieur 10 permet de maintenir la pression de contact à la valeur de limite d'élasticité biomécanique de la peau de la tette 11.The dimension of the contour of the upper edge 10 makes it possible to maintain the contact pressure at the biomechanical elastic limit value of the skin of the pad 11.

La zone de réaction du contact s'étend sur toute la périphérie du manchon 7, de manière à éviter partout une fuite de composition médicamenteuse vers l'extérieur.The contact reaction zone extends over the entire periphery of the sleeve 7, so as to avoid everywhere a leakage of medicinal composition towards the outside.

Un troisième avantage réside dans le fait que le capuchon 4 ne peut plus être réutilisé pour obturer la pointe de la canule 3, après que la partie supérieure 8 du capuchon ait été brisée.A third advantage lies in the fact that the cap 4 can no longer be reused to close off the tip of the cannula 3, after the upper part 8 of the cap has been broken.

La partie supérieure 8 du capuchon 4 est en fait utilisée en tant qu'anneau de scellement pour garantir l'inviolabilité de la canule. Il assure la stérilité du conditionnement de l'instrument rempli de composition médicamenteuse. Pour mieux obturer la canule, le côté intérieur de la coiffe comprend un cône d'étanchéité 14.The upper part 8 of the cap 4 is in fact used as a sealing ring to guarantee the inviolability of the cannula. It ensures the sterility of the packaging of the instrument filled with medicinal composition. To better seal the cannula, the inner side of the cap includes a sealing cone 14.

La partie supérieure 8 se distingue d'un capuchon classique par le fait que l'extrémité fermée est prolongée par une saillie cylindrique 15 suffisamment rigide que pour permettre au pouce d'y prendre appui pour briser la coiffe à sa base et la détacher du capuchon 4.The upper part 8 is distinguished from a conventional cap by the fact that the closed end is extended by a cylindrical projection 15 which is rigid enough to allow the thumb to rest on it to break the cap at its base and detach it from the cap. 4.

La partie cylindrique 15 est de préférence pleine intérieurement et pourvue de nervures extérieures 16 en vue de réduire la consommation de matière synthétique lors du moulage.The cylindrical part 15 is preferably internally full and provided with external ribs 16 in order to reduce the consumption of synthetic material during molding.

Le capuchon 4 selon l'invention présente l'avantage de pouvoir être manipulé d'une seule main. Cet avantage a toute son importance, lorsqu'il s'agit de soigner des animaux qu'il faut tenir agrippé de l'autre main.The cap 4 according to the invention has the advantage of being able to be manipulated with one hand. This advantage is very important, when it comes to caring for animals that must be held gripped with the other hand.
