Abstract

The device is characterised, according to the invention, in that it comprises a protecting and sealing device, in particular for an auto-injectable syringe needle, characterised in that it comprises a rigid envelope 1 in the form of an approximately cylindrical tube, closed at one of its ends, containing an elastomeric material 2 suitable for receiving the needle 3 of the said syringe in such a way that the needle can be driven into the elastomeric material, the latter sealing off the end of this needle.

Description

La présente invention a pour objet un dispositif de protection et d'étanchéification notamment pour seringue auto-injectable. The present invention relates to a protection and sealing device in particular for a self-injecting syringe.

On entend par seringue auto-injectable une seringue hypodermique è usage médical unique. montée d'une aiguille et contenant la spécialité pharmaceutique devant entre injectée. By self-injecting syringe is meant a hypodermic syringe for single medical use. rise of a needle and containing the pharmaceutical specialty between injected.

Pour rendre étanche les seringues autoinjectables. 1 usage en vigueur est qu un protecteur en élastomère vienne coiffer 1 aiguille, ladite aiguille étant piquée dans une partie de ce protecteur. To seal autoinjectable syringes. 1 current use is that an elastomer protector comes over 1 needle, said needle being pricked in part of this protector.

Le fait d entre piquée dans cet élastomère bouche l'aiguille et par conséquent rend étanche la seringue de sorte que le liquide qu'elle contient y reste.The fact of being inserted into this elastomer plugs the needle and consequently seals the syringe so that the liquid which it contains remains there.

Le problème majeur que crée ce dispositif est que l'infirmiere ou le personnel soignant. après l'injection. rebouche la seringue â l'aide de ce protecteur et souvent. si l'aiguille est légèrement décentrée l'opérateur se pique car l'aiguille traverse la paroi de 1 élastomère. Outre le désagrément d'un tel accident. l'opérateur est alors soumis au danger latent de l'hépatite B, voire du SIDA. The major problem created by this device is that of the nurse or the nursing staff. after the injection. cap the syringe with this protector and often. if the needle is slightly off center the operator pricks because the needle crosses the wall of 1 elastomer. Besides the inconvenience of such an accident. the operator is then subjected to the latent danger of hepatitis B, or even AIDS.

La présente invention a pour but de pallier â ce problème. Elle permet d'assurer l'étanchéité de la seringue tout en protégeant l'opérateur. The present invention aims to overcome this problem. It ensures the tightness of the syringe while protecting the operator.

L'invention a donc pour objet un dispositif de protection et d'étanchéification notamment pour aiguille de seringue auto-injectable. caractérisé en ce qu'il comprend une enveloppe rigide se présentant sous la forme d'un tube â peu prés cylindrique. fermé â l'une de ses extrémités. et contenant un matériau élastomère adapté pour recevoir l'aiguille de ladite seringue. de sorte que l'aiguille puisse entre enfoncée dans le matériau élastomère, celui-ci bouchant l-ex- trémité de cette aiguille. The subject of the invention is therefore a protection and sealing device, in particular for a self-injecting syringe needle. characterized in that it comprises a rigid envelope in the form of a roughly cylindrical tube. closed at one end. and containing an elastomeric material adapted to receive the needle of said syringe. so that the needle can enter the elastomeric material, the latter blocking the end of this needle.

L'enveloppe rigide peut etre en particulier en un matériau polymère tel que le polyéthylène. polypropylène, polycarbonate. polychiorure de vinyle, etc. The rigid envelope may in particular be made of a polymer material such as polyethylene. polypropylene, polycarbonate. polyvinyl chloride, etc.

éventuellement chargé et ayant une dureté suffisante pour que l'aiguille ne la transperce pas si l'opérateur 1 enfonce brusquement dans le dispositif. Elle peut comprendre un rebord à son extrémité ouverte.possibly loaded and having sufficient hardness so that the needle does not pierce it if operator 1 abruptly presses into the device. It may include a flange at its open end.

Cette enveloppe contient un matériau élastomère naturel en synthétique. par exemple du latex, du caoutchouc, du polyisoprène. un caoutchouc butyle ou nitrile, une silicone, etc. susceptible d'être traversé par l'aiguille et bouchant l'extrémité de celleci pour assurer 1 etancheite de la seringue. Le matériau élastomère peut être fixé à l'enveloppe par collage. encliquetage. ou encore par un moulage. This envelope contains a natural elastomeric synthetic material. for example latex, rubber, polyisoprene. butyl or nitrile rubber, silicone, etc. likely to be crossed by the needle and blocking the end of it to ensure 1 tightness of the syringe. The elastomeric material can be attached to the envelope by gluing. snap-on. or by molding.

Selon une variante, la partie extérieure du matériau élastomère (du cote de l'extrémité ouverte de 1 enveloppe) peut présenter un évasement afin de faciliter l'insertion de l'aiguille. Par ailleurs, le matériau élastomère peut contenir un agent désinfectant maintenant la stérilité de l'aiguille. Alternatively, the outer part of the elastomeric material (on the side of the open end of 1 envelope) may have a flare in order to facilitate the insertion of the needle. Furthermore, the elastomeric material may contain a disinfecting agent maintaining the sterility of the needle.

Il est entendu que le dispositif selon l'in- vention est utilisable pour toute aiguille ou canule effilée a' usage médical ou chirurgical. It is understood that the device according to the invention can be used for any needle or tapered cannula for medical or surgical use.

La description suivante en regard du dessin annexé est donnée à titre d'exemple illustrant l'in- vention. The following description with reference to the appended drawing is given by way of example illustrating the invention.

Sur ce dessin, la figure unique représente une vue en coupe d'un dispositif de protection et d'étanchéification notamment pour aiguille de seringue auto-injectable. avec une aiguille.  In this drawing, the single figure represents a sectional view of a protection and sealing device, in particular for a self-injecting syringe needle. with a needle.

Le dispositif comprend une enveloppe rigide 1 en polypropylène d'environ o. e mm d'épaisseur, se présentant sous la forme d'un tube â peu près cylindrique d'environ Xmm de diamètre et de 5 cm de lon gueur. fermé à l'une de ses extrémités et contenant un matériau élastomère 2, tel que du latex, adapté pour recevoir l'aiguille 3 d'une seringue. et fixé à l'enveloppe 1 au moyen d'une colle néoprène. L'aiguille 3 enfoncée dans le matériau élastomère 2 est bouchée à son extrémité par celui-ci, de sorte qu'elle est à la fois protégée vis-à-vis de l'extérieur et êtanchéi- fiée. empêchant l'écoulement de la spécialité contenue dans la seringue. De plus, l'opérateur est protégé par 1 enveloppe 1 et ne risque pas de se piquer avec l'aiguille 3 si par maladresse il l'enfonce trop brusque-ment dans le dispositif. Afin de rendre encore plus aisée cette manipulation, l'enveloppe 1 comprend un rebord 4 à son extrémité ouverte et la partie extérieure du matériau élastomère 2 présente un évasement 5.  The device comprises a rigid envelope 1 of polypropylene of approximately 0. e mm thick, in the form of a roughly cylindrical tube of about Xmm in diameter and 5 cm in length. closed at one of its ends and containing an elastomeric material 2, such as latex, suitable for receiving the needle 3 of a syringe. and fixed to the casing 1 by means of a neoprene adhesive. The needle 3 pressed into the elastomeric material 2 is plugged at its end by the latter, so that it is both protected from the outside and sealed. preventing the flow of the specialty contained in the syringe. In addition, the operator is protected by 1 envelope 1 and is not likely to prick himself with the needle 3 if, by mistake, he pushes it too abruptly into the device. In order to make this manipulation even easier, the envelope 1 comprises a flange 4 at its open end and the outer part of the elastomeric material 2 has a flare 5.
