Abstract

The invention relates to a an injection material designed to be impossible to be reused after it has been used once. It is comprised of a syringe of which the nozzle (9) provided with barbs (12) prolonges a cylindrical mouthpiece (6) with which it is weakly integral. The piston of the syringe (13) is provided with an extension (14) which, when the piston is at the end of the stroke, acts as the pusher thus detaching the nozzle (9) from the mouthpiece (6), and housing it in the cavity (17) (also provided with barbs (18)) of the mandrel of the needle (16), wherein it remains blocked due to the meshing of the barbs (12 and 18). Unusable after a single utilization, syringe and needle of the invention contribute to the prevention of diseases such as AIDS, without extra cost with respect to conventional injection material.

Description

L'invention concerne un matériel à injection seringue et aiguille. The invention relates to syringe and needle injection equipment.

Le matériel à injection à "usage unique" conventionnel comporte une seringue et une aiguille. La seringue est faite d'un corps cylindrique dans lequel coulisse un piston, et dont la base porte un ajustage sur lequel s'adapte le mandrin d'une aiguille amovible. Seringue et aiguille sort livrés en emballage. stérile et doivent être jetés après usage pour raison d'aseptie. Conventional "single use" injection equipment includes a syringe and needle. The syringe is made of a cylindrical body in which slides a piston, and the base of which carries an adjustment on which the mandrel of a removable needle fits. Syringe and needle comes out in packaging. sterile and must be discarded after use due to aseptic reasons.

Or, pour des raisons de conditions de vente réglementées, des raisons d'économie, ou tout simplement parce que la ré-utilisation est matériellement possible ( en dehors de la raison d'aseptie ), il est fréquent que seringue et aiguille à "usage unique" conventionnels soient utilisés plusieurs fois, notamment dans les milieux toxicomanes Ce matériel présente donc l'inconvénient majeur de pouvoir propager, essentiellement par l'aiguille ( en contact direct avec le sang ), des maladies graves ou mortelles telles que l'hépatite B et le S.I.D..  However, for reasons of regulated conditions of sale, reasons of economy, or simply because re-use is materially possible (apart from the reason of aseptic), it is frequent that syringe and needle for "use single "conventional are used several times, especially in drug addicts This material therefore has the major disadvantage of being able to spread, mainly by the needle (in direct contact with the blood), serious or fatal diseases such as hepatitis B and the SID.

La présente invention a pour but de remédier à cet inconvé- nient et propose à cet effet un matériel à injection conçu de manière telle que la seringue et l'aiguille ne soient matérieller::ent plus utilisables aprés usage unique. The object of the present invention is to remedy this drawback and to this end provides an injection device designed in such a way that the syringe and the needle cannot be used any more after single use.

Le corps de la seringue est muni à sa base d'un embout cylindrique creux, de section supérieure à celle de l'ajustage et dont la cavité intérieure a une section plus étroite dans sa partie proximale ( par rapport à la base de la seringue > ), que dans sa partie distale. The body of the syringe is provided at its base with a hollow cylindrical tip, of section greater than that of the adjustment and whose inner cavity has a narrower section in its proximal part (relative to the base of the syringe> ), only in its distal part.

Suivant une autre caractéristique de l'invention, l'ajustage est enchâssé par sa partie proximale cylindrique à l'intérieur de la partie distale à large section de l'embout, de manière telle que la partie proximale à faible section de l'embout forme une butée empêchant un déplacement de l'ajustage dans le sens antéropostérieur. L'ensemble formé par l'embout et l'ajustage, est réalisé de manière telle que qu'il soit étanche, mais rendu faiblement solidaire ( par un moulage adéquat
Suivant une autre caractéristique de l'invention, la partie distale conique de l'ajustage est munie de reliefs circulaires moulés formant des barbillons.According to another characteristic of the invention, the fitting is enshrined by its cylindrical proximal part inside the distal part with a large section of the end piece, so that the proximal part with a small section of the end piece forms a stop preventing movement of the adjustment in the anteroposterior direction. The assembly formed by the end piece and the adjustment, is made in such a way that it is watertight, but made weakly integral (by an adequate molding
According to another characteristic of the invention, the conical distal part of the fitting is provided with molded circular reliefs forming barbs.

Suivant une autre caractéristique ##- l!invention, le piston de la seringue est pourvu sur son extrémité répondant à la base de la seringue, d'un prolongement de section étroite légèrement infri- eure à la section cylindrique étroite de la partie proximale de l'embout où il est susceptible de s'engager et de coulisser. La longueur du prolongement est égale à celle de l'embout, de sorte que son extrémité vient buter contre l'extrémité proximale de l'ajustage enchâssé dans la partie distale de l'embout, avant que le piston de la seringue ne soit en bout de course.Le prolongement est donc susceptible d'agir comme un poussoir désolidarisant l'ajustage de l'embout cylindrique et le chassant vers l'avant lorsque le piston de la seringue est poussé en bout de course.  According to another characteristic ## - the invention, the plunger of the syringe is provided on its end corresponding to the base of the syringe, with an extension of narrow section slightly less than the narrow cylindrical section of the proximal part of the tip where it is likely to engage and slide. The length of the extension is equal to that of the tip, so that its end abuts the proximal end of the fitting embedded in the distal part of the tip, before the syringe plunger is at the end The extension is therefore likely to act as a pusher separating the adjustment of the cylindrical tip and driving it forward when the syringe piston is pushed to the end of travel.

position dans laquelle ltextrémité distale du prolongement affleure celle de l'embout.position in which the distal end of the extension is flush with that of the end piece.

Suivant une autre caractéristique de l'invention, le mandrin en matière plastique de l'aiguille, ( formant la partie femelle s'adaptant sur la partie distale conique de l'ajustage ), est réalisé de manière telle que sa cavité comporte des reliefs circulaires formant des barbillons susceptibles de s'engrener dans ceux, disposés en sens inverse dont est munie la partie conique de l'ajustage. According to another characteristic of the invention, the plastic mandrel of the needle (forming the female part fitting onto the conical distal part of the adjustment) is produced in such a way that its cavity has circular reliefs forming barbels likely to mesh with those, arranged in the opposite direction with which the conical part of the adjustment is provided.

In the invention, the body of the syringe 5 is provided at its base with a cylindrical tip 6, which includes a proximal part of narrow section 7.

et une partie distale de section large 8. L'ajustage 9 comprend une partie proximale 10 enchâssée dans la partie distale 8 de l'embout, et une partie distale conique 11, munie de barbillons 12.and a distal part of wide section 8. The fitting 9 comprises a proximal part 10 embedded in the distal part 8 of the endpiece, and a conical distal part 11, provided with barbs 12.

Le piston 13 est pourvu d'un prolongement 14, susceptible de s'engager et de coulisser dans la partie proximale de section étroite 7 de l'embout 6. L'aiguille 15 est pourvue d'un mandrin 16, dont la cavité 17 est munie de barbillons 18 susceptibles de s'engrener dans les barbillons 12 de la partie conique 11 de l'ajustage.The piston 13 is provided with an extension 14, capable of engaging and sliding in the proximal part of narrow section 7 of the endpiece 6. The needle 15 is provided with a mandrel 16, the cavity 17 of which is provided with barbs 18 capable of meshing with the barbs 12 of the conical part 11 of the fitting.

La figure 3 représente le prolongement 14 venant buter contre la partie proximale 10 de l'ajustage 9, et agissant comme poussoir pendant la course du piston 13. L'ajustage 9 est désolidarisé de l'embout 6, et propulsé "en force" dans la cavité 17 du mandrin 16 de l'aiguille. FIG. 3 represents the extension 14 abutting against the proximal part 10 of the fitting 9, and acting as a plunger during the stroke of the piston 13. The fitting 9 is detached from the nozzle 6, and propelled "in force" in the cavity 17 of the mandrel 16 of the needle.

La figure 4 représente le prolongement 14 lorsque le piston 13 de la seringue est à bout de course ; l'extrémité du prolongement 14 affleure l'extrémité de l'embout 6. FIG. 4 represents the extension 14 when the piston 13 of the syringe is at the end of its travel; the end of the extension 14 is flush with the end of the endpiece 6.

La figure 5 représente la seringue sans son ajustage 9, qui est bloqué dans la cavité 17 du mandrin 16, par l'engrenage "en force" des barbillons 12 et 18. FIG. 5 represents the syringe without its adjustment 9, which is blocked in the cavity 17 of the mandrel 16, by the gear "in force" of the barbs 12 and 18.

La figure 6 représente un mode de réalisation d'une seringue selon 1 invention où l'ajustage n'est pas enchâssé dans la partie distale de l'embout, mais moulé d'un seul bloc dans son prolongement, avec une zone faiblement solide 19, constituant la zone de séparation lorsque le piston arrive en bout de course. FIG. 6 represents an embodiment of a syringe according to 1 invention where the fitting is not embedded in the distal part of the tip, but molded in one piece in its extension, with a weakly solid area 19 , constituting the separation zone when the piston reaches the end of its travel.

Ainsi, l'usage d'un matériel d'injection conforme à l'invention rend impossible une utilisation répétée tant de la seringue que de l'aiguille devenue inutilisable après usage. Thus, the use of injection equipment according to the invention makes it impossible to use it repeatedly, both the syringe and the needle which become unusable after use.

Ce matériel facilement réalisable ne demande qu'une modification des moules de fabrication des seringues et des aiguilles son prix de revient serait sensiblement le même que celui du matériel conventionnel.This easily achievable material requires only a modification of the molds for manufacturing syringes and needles, its cost price would be substantially the same as that of conventional equipment.

L'impossibilité de ré-utiliser le matériel d'injection permectrait sa vente libre en- pharmacie. L'inutilité et l'impossibilité pour les toxicomanes d'utiliser le même matériel à injection de façon répétée, permettrait d'éviter la dissémination par voie sanguine de l'hépatite B et du S.I.D.A. en constante augmentation The impossibility of re-using the injection equipment would allow its free sale in pharmacies. The uselessness and the impossibility for drug addicts to use the same injection equipment repeatedly, would prevent the spread by blood of hepatitis B and S.I.D.A. constantly increasing
