Abstract

The system consists of a hollow needle (1) which is fitted into a holder (2) connected to a syringe barrel. The needle is covered by a plastic sleeve (4) which is kept in place prior to and during use. The sleeve is attached to the holder by breaking points (5', 7) on each side. One the needle has been used the sleeve is sepd. from the holder at the breaking points, which are formed by inner projections in the sleeve engaging with recesses in the holder, leaving holes in the sides of the holder which prevent the syringe from being reused. ADVANTAGE - Reduces risk of accidental injury with needle and reuse of syringe.

Description

L'invention se rapporte à un dispositif de sécurité permettant de rendre inopérant une aiguille et/ou un corps de seringue après un premier usage, en ce qu'il permet
- d'empêcher une piqure accidentelle après une première utilisation.The invention relates to a safety device making it possible to render a needle and / or a syringe body inoperative after a first use, in that it allows
- to prevent an accidental bite after a first use.

de rendre l'aiguille d'injection inopérante après une première utilisation. make the injection needle inoperative after a first use.

Dans le domaine thérapeutique, une aiguille d'injection se présente d'une part d'une aiguille creuse (1), par exemple en acier ou en nickel, ledit corps formant un réservoir pour le liquide à injecter, et d'autre part, d'une structure en plastique rigide (3), permettant l'ajustement à l'embout d'une seringue. In the therapeutic field, an injection needle has on the one hand a hollow needle (1), for example of steel or nickel, said body forming a reservoir for the liquid to be injected, and on the other hand, a rigid plastic structure (3), allowing adjustment to the tip of a syringe.

L'aiguille (1) est enfilée dans cette formation en plastique (3) et maintenue par un collage (2). The needle (1) is threaded into this plastic formation (3) and held by an adhesive (2).

Un étui (4) en plastique rigide, de la dimension de l'aiguille (1), vient encapuchonner l'aiguille (1) et la formation plastique (3), afin de protéger celle-ci avant l'utilisation, et protéger d'une piqure accidentelle en fin de manipulation. A rigid plastic case (4), the size of the needle (1), encapsulates the needle (1) and the plastic formation (3), in order to protect the latter before use, and protect against '' an accidental bite at the end of handling.

L'invention consiste en un moyen visant à fixer de façon quasi irréductible l'étui (4) sur l'aiguille (1) et la formation plastique (3) en fin de manipulation, et dans le même temps, à perforer cette formation plastique (3) de l'aiguille, mettant ainsi l'intérieur de cette formation (3) en relation avec l'extérieur (fig. 9), de telle sorte que toute tentative ultérieure d'injection de produit dans l'aiguille s'avererait impossible, le produit passant par cette perforation vers l'extérieur, avant de pouvoir s'écouler dans l'aiguille.  The invention consists of a means aiming to fix in an almost irreducible manner the case (4) on the needle (1) and the plastic formation (3) at the end of handling, and at the same time, to perforate this plastic formation. (3) of the needle, thus putting the inside of this formation (3) in relation to the outside (fig. 9), so that any subsequent attempt to inject product into the needle would prove impossible, the product passing through this perforation outwards, before being able to flow into the needle.

Il faut prévoir sur la formation plastique (3) de l'aiguille, au moins une formation (5) (ou plus), de la même matière plastique, arrondie ou non, renflée vers l'extérieur, faisant saillie par rapport à l'enveloppe générale de ladite formation, cette partie (5) présentant une zone de fragilisation (6) à sa base, de telle sorte qu'il soit possible de faire sauter ce petit renflement (5), créant ainsi un trou (5'), mettant en relation l'intérieur avec l'extérieur. It is necessary to provide on the plastic formation (3) of the needle, at least one formation (5) (or more), of the same plastic material, rounded or not, swollen towards the outside, projecting with respect to the general envelope of said formation, this part (5) having a weakening zone (6) at its base, so that it is possible to blow up this small bulge (5), thus creating a hole (5 '), connecting the interior with the exterior.

Il faut prévoir sur l'étui protecteur (4) de l'aiguille, la (ou les) même(s) formation(s) (7), mais présentant le renflement vers l'intérieur, de la même structure que l'étui (4), non fragilisé, de telle sorte que ce renflement corresponde à la partie mâle du (ou des) trou(s) (5') prévu dans la formation plastique (3) de l'aiguille (1). It is necessary to provide on the protective case (4) of the needle, the (or) same (s) formation (s) (7), but having the bulge inwards, of the same structure as the case (4), not weakened, so that this bulge corresponds to the male part of the hole (s) (5 ') provided in the plastic formation (3) of the needle (1).

Après une utilisation de l'aiguille, il suffit d'enfiler le capuchon protecteur (4) de l'aiguille sur celle-ci et d'exercer une pression suffisante afin que la partie proximale du capuchon (4) fasse sauter la (ou les) structure(s) en relief (5) fragilisée(s) de la formation plastique (3) ; et le (ou les) renflement fixe (t) intérieur de l'étui s'engage élastiquement dans le (ou les) trou(s) (5') qui vient d'apparaître au niveau de la formation plastique (3) de l'aiguille. After using the needle, simply thread the protective cap (4) of the needle on it and exert sufficient pressure so that the proximal part of the cap (4) causes the (or ) structure (s) in relief (5) weakened (s) of the plastic formation (3); and (or) fixed bulge (t) inside the case engages elastically in (or) hole (s) (5 ') which has just appeared at the level of the plastic formation (3) of the 'needle.

Cet engagement élastique est quasiment indémontable, puisqu'il faudrait exercer une pression à l'intérieur de la formation plastique (3) pour desolidariser l'étui protecteur (4), celui-ci ne peut donc pas se sortir accidentellement et toute piqure accidentelle ultérieure est écartée. This elastic engagement is practically impossible to dismantle, since pressure would have to be exerted inside the plastic formation (3) to separate the protective case (4), the latter therefore cannot be accidentally removed and any subsequent accidental bite. is discarded.

Si malgré tout, l'étui protecteur (4) parvenait à se retirer de l'aiguille, il serait impossible de réutiliser cette aiguille, puisqu'elle présente maintenant un (ou plusieurs) trou(s) (5) mettant en relation l'intérieur de la formation plastique (3) avec l'extérieur (fig. 9). If in spite of everything, the protective case (4) succeeds in withdrawing from the needle, it would be impossible to reuse this needle, since it now has one (or more) hole (s) (5) connecting the inside of the plastic formation (3) with the outside (fig. 9).

Le même système peut être bien évidemment adapté au corps de seringue, visant à ne plus pouvoir actionner le piston après une première utilisation.  The same system can obviously be adapted to the syringe body, aiming to no longer be able to actuate the plunger after a first use.
