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

MATERIEL A INJECTION (SERINGUE ET AIGUILLE) INUTILISABLE APRES USAGE.  INJECTION MATERIAL (SYRINGE AND NEEDLE) UNUSABLE AFTER USE.
L'invention concerne un matériel à injection :  The invention relates to injection equipment:
seringue et aiguille.  syringe and needle.
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 sont 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 a piston slides, and the base of which carries an adjustment on which the mandrel of a removable needle fits. Syringe and needle are delivered in sterile packaging 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 réutilisation 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. Oe 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.A.  However, for reasons of regulated conditions of sale, reasons of economy, or quite simply because reuse is materially possible (apart from the reason of aseptic), it is frequent that syringe and needle for "single use" conventional are used several times, especially in drug addicts. This material therefore has the major drawback of being able to propagate, essentially by the needle (in direct contact with the blood), serious or fatal diseases such as hepatitis B and S.I.D.A.
La présente invention a pour but de remédier à cet inconvénient et propose a cet effet un matériel à injection conçu de manière telle que la seringue et l'aiguile ne soient matériellement plus utilisables après usage unique. The object of the present invention is to remedy this drawback and for this purpose proposes an injection equipment designed in such a way that the syringe and the needle are no longer physically usable 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'ajusxage 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 nozzle 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 I nvention, 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 antéro-postérieur. L'ensemble formé par l'embout et l'ajustage, est réalisé de manière telle qu'il soit ètanche, mais rendu faiblement solidaire (par un moulage adéquat). Suivant une autre caracterxstique αe 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 small section of the end piece forms a stop preventing displacement of the adjustment in the antero-posterior direction. The assembly formed by the end piece and the adjustment, is made in such a way that it is waterproof, 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 de l'invention, le piston de la seringue est pourvu sur son extrémité répondant a la base de la seringue, d'un prolongement de section étroite légèrement inférieure 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 a celle de l'embout, de sorte que son extrémité vient buter contre l'extrémité proximale de l'ajustage enchâsse 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 αe l'embout cylindrique et le chassant vers l'avant lorsque le piston de la seringue est poussé en bout de course, position dans laquelle l'extrémité distale du prolongement affleure celle de l'embout.  According to another characteristic of the invention, the plunger of the syringe is provided at 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 nozzle where it is likely to engage and slide. The length of the extension is equal to that of the endpiece, so that its end abuts against the proximal end of the fitting embedded in the distal part of the endpiece, before the syringe plunger is at the end race. The extension is therefore likely to act as a pusher separating the adjustment αe the cylindrical tip and driving it forward when the syringe piston is pushed to the end of travel, position in which the distal end of the extension is flush that of the nozzle.
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 adapting to 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 which is provided with the conical part of the adjustment.
L'invention est représentée a titre d'exemples non limitatifs sur les dessins ci-joint dans lesquels :  The invention is shown by way of nonlimiting examples in the attached drawings in which:
-La figure 1 est une vue en coupe axiale schématique d'un matériel à injection "usage unique" conventionnel : seringue et aiguille.  FIG. 1 is a schematic axial section view of a conventional "single use" injection equipment: syringe and needle.
-La figure 2a est une vue en coupe axiale schématique au matériel à injection usage unique selon l'invention : seringue et aiguille à ré-utilisation impossible.  FIG. 2a is a schematic axial section view of the single-use injection equipment according to the invention: syringe and needle for reuse impossible.
-La figure 2b est un agrandissement en vue partielle de la zone de la base du corps de seringue et du mandrin de l'aiguille de la figure 2a.  FIG. 2b is an enlargement in partial view of the area of the base of the syringe body and of the mandrel of the needle of FIG. 2a.
-Les figures 3 et 4 représentent en vue partielle la zone de la base du corps de la seringue et au mandrin αe l'aiguille pour des positions différentes au piston. -La figure 5 represente la seringue et l'axguille rendues inutilisables après usage. FIGS. 3 and 4 show in partial view the area of the base of the body of the syringe and of the mandrel of the needle for different positions with the piston. FIG. 5 represents the syringe and the axillion rendered unusable after use.
-Les figures 6a et p sont des coupes axiales scnemaxigues d'un mode de réalisaxion au matériel selon l'invention avant et après utilisation.  FIGS. 6a and p are axial scnemaxigues sections of an embodiment of the material according to the invention before and after use.
La figure 1 représente une seringue conventionnelle; le piston 2 coulisse dans le corps 1 de la seringue qui porte un ajustage 3, sur lequel s'adapte le mandrin 4, de l'aiguille. Les figures 2a et 2b représentent une seringue conforme à l'invention : le corps de la seringue 5, est muni à sa base d'un embout cylindrique 6, qui comprend une partie proximale de section étroite 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.  Figure 1 shows a conventional syringe; the piston 2 slides in the body 1 of the syringe which carries an adjustment 3, on which the mandrel 4, of the needle fits. FIGS. 2a and 2b represent a syringe according to the invention: the body of the syringe 5, is provided at its base with a cylindrical tip 6, which comprises a proximal part of narrow section 7, and a distal part of wide section 8. The fitting 9 comprises a proximal part 10 embedded in the distal part 8 of the end piece, 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'emoout 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 nozzle 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 outer contre la partie proximale 10 de l'ajustage 9, et agissant comme poussoir pendant la course au piston 13. L'ajustage 9 est désolidarise de l'emoout 6, et propulse "en force" dans la cavite 17 au manarin 16 ae l'aiguille.  FIG. 3 represents the extension 14 coming from outside 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 propels "in force" into cavity 17 with manarin 16 at the needle.
La figure 4 represente 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 bloque dans la cavité 17 au mandrin 16, par l'engrenage "en force" des barbillons 12 et 13. FIG. 5 represents the syringe without its adjustment 9, which is blocked in the cavity 17 in the mandrel 16, by the gear "in force" of the barbs 12 and 13.
Les figures 6a et 6b représentent un mode de réalisation d'une seringue selon l'invention ou l'ajustage 9 n'est pas enchâssé dans la partie distale de l'embout 6, mais moulé d'un seul bloc dans son prolongement, avec une zone faiblement solide 16, constituant la zone de séparation lorsque le piston 13 arrive en bout de course. La figure 6b représente le prolongement 14 depassant la partie distale de l'embout 6 lorsque le piston 13 est en DOUX de course. L'ajustage 9 sépare de 1 embout 6 est bloque dans le mandrin 16 par engrenage des baroillons 12 et 18. Figures 6a and 6b show an embodiment of a syringe according to the invention or the fitting 9 is not embedded in the distal part of the tip 6, but molded in one piece in its extension, with a weak solid zone 16, constituting the separation zone when the piston 13 reaches the end of its travel. FIG. 6b represents the extension 14 extending beyond the distal part of the endpiece 6 when the piston 13 is in SOFT stroke. The adjustment 9 separates from 1 end piece 6 is locked in the mandrel 16 by gear barions 12 and 18.
Ainsi. 1 usage d'un matériel d'injection conforme a l'invention rend impossible une utilisation répétée tant de la seringue que de l'aiguille devenue inuxilisable appres usage. Oe matériel facilemenx réalisable ne demande au une moaification des moules de fabrication des seringues et des aiguilles: son prix αe revient serait sensiblemenx le même que celui au matériel conventionnel.  So. 1 use of an injection material according to the invention makes it impossible to repeat use both the syringe and the needle become unusable after use. This easily achievable material does not require a modification of the molds for manufacturing syringes and needles: its cost price would be appreciably the same as that for conventional equipment.
L 'impossibilité de re-utiliser le matériel d'injection permettrait sa vente libre en pnarmacie. L 'inutilité et 1 impossibilite pour les toxicomanes d'utiliser le même matenel a injection de façon repetee, permettrait d'éviter la disse- mination par voie sanguine de 1 nepatite B et du S.I.D.A. en constante augmentation.  The impossibility of re-using the injection equipment would allow its free sale in pnarmacie. The uselessness and the impossibility for drug addicts to use the same injection equipment repeatedly, would prevent the spread by blood of 1 nepatitis B and S.I.D.A. constantly increasing.
