Abstract

A hypodermic syringe needle guard device for preventing post-injection needlestick accidents is disclosed. The device removes any risk of sticking with a contaminated needle following injection. The device consists of a hypodermic syringe (5) provided with a flange (6), a plunger (9) and a groove (7), and a cylindrical barrel (1) with a bevelled edge (3) and an inner projection (2). Following injection, the user manually pushes the cylindrical barrel (1) until the projection (2) engages the groove (7). The needle is then shielded, there is no risk of a needlestick accident, and the syringe cannot be reused.

Description

DISPOSITIF DE PROTECTION D'AIGUILLE DE SERINGUE HYPODERMIQUE CONTRE LES PIQURES ACCIDENTELLES APRES INJECTION DEVICE FOR PROTECTING A HYPODERMIC SYRINGE NEEDLE FROM ACCIDENTAL PUNCHES AFTER INJECTION
La présente invention concerne un dispositif permettant d'éviter de se blesser avec une aiguille souillée après une injection avec une seringue hypodermique.The present invention relates to a device for avoiding injury with a dirty needle after an injection with a hypodermic syringe.
Actuellement, le seul dispositif connu sur le marché est un capuchon que l'on met sur l'aiguille après usage, ce qui n'élimine pas les risques de piqûres. Le dispositif selon l'invention permet de remédier à cet inconvénient. Il comporte, en effet, selon une première caractéristique, un tube cylindrique transparent de même composition que la seringue utilisée actuellement. Ce tube a la particularité d'avoir à l'intérieur :Currently, the only known device on the market is a cap that is put on the needle after use, which does not eliminate the risk of bites. The device according to the invention overcomes this drawback. In fact, it comprises, according to a first characteristic, a transparent cylindrical tube of the same composition as the syringe currently used. This tube has the distinction of having inside:
- une saillie circonférencielle interne,- an internal circumferential projection,
- un chanfrein sur une extrémité interne, Selon une deuxième caractéristique, il comporte une seringue ayant la particularité d'avoir une gorge circonférentielle de forme identique à la saillie interne du tube cylindrique.- a chamfer on an internal end, According to a second characteristic, it comprises a syringe having the distinction of having a circumferential groove of identical shape to the internal projection of the cylindrical tube.
Selon des modes particuliers de réalisation :According to particular embodiments:
- la saillie et la gorge peuvent être réalisées de forme différente à condition qu'elles puissent s'épouser, - le corps de la seringue peut être plus épais.- the protrusion and the throat can be made in a different shape provided that they can fit together, - the syringe body can be thicker.
Les dessins annexés illustrent l'invention :The accompanying drawings illustrate the invention:
- la figure 1 représente en coupe le tube cylindrique,- Figure 1 shows in section the cylindrical tube,
- la figure 2 représente en coupe la seringue modifiée,FIG. 2 represents in section the modified syringe,
- la figure 3 représente en coupe le dispositif selon l'invention, avant usage, - la figure 4 représente en coupe le dispositif selon l'invention, après usage.- Figure 3 shows in section the device according to the invention, before use, - Figure 4 shows in section the device according to the invention, after use.
En référence à la figure 1, le dispositif comporte un tube cylindrique (1) muni d'une saillie interne (2) d'un chanfrein interne (3).Referring to Figure 1, the device comprises a cylindrical tube (1) provided with an internal projection (2) with an internal chamfer (3).
En référence à la figure 2, le dispositif comporte une seringue hypodermique (5) munie d'une collerette (6), d'une gorge (7), d'un piston (9).Referring to Figure 2, the device comprises a hypodermic syringe (5) provided with a flange (6), a groove (7), a piston (9).
En référence à la figure 3, le dispositif représente les deux parties assemblées avant usage, une déformation (8) (exagérée pour une meilleure compréhension).Referring to Figure 3, the device shows the two parts assembled before use, a deformation (8) (exaggerated for better understanding).
En référence à la figure 4, le dispositif représente la seringue après son utilisation. La saillie (2) et la gorge (7) jouent un rôle de blocage ; l'aiguille est protégée.Referring to Figure 4, the device shows the syringe after use. The projection (2) and the groove (7) play a blocking role; the needle is protected.
...A. L'assemblage de la seringue (figure 2) et du tube cylindrique (figure 1) se fera avant le collage de la collerette (6). La partie chanfreinée (3) du tube cylindrique facilite cette opération (qui pourrait être mécanique), d'autant que le tube cylindrique a un diamètre intérieur à peine supérieur au diamètre extérieur de la seringue....AT. The syringe (figure 2) and the cylindrical tube (figure 1) will be assembled before the collar (6) is glued. The chamfered part (3) of the cylindrical tube facilitates this operation (which could be mechanical), all the more so since the cylindrical tube has an internal diameter barely greater than the external diameter of the syringe.
Le passage de la saillie interne (2) peut se faire sans difficulté, compte tenu de l'élasticité desmatériaux utilisés et aussi, compte tenu de l'épaisseur de cette saillie.The passage of the internal projection (2) can be done without difficulty, taking into account the elasticity of the materials used and also, taking into account the thickness of this projection.
La déformation (8) (exagérée pour une meilleure compréhension) de la seringue et du tube cylindrique (1) n'empêche pas le déplacement du piston en caoutchouc (9) selon les désirs de l'utilisateur.The deformation (8) (exaggerated for a better understanding) of the syringe and the cylindrical tube (1) does not prevent the displacement of the rubber piston (9) according to the wishes of the user.
Selon une variante illustrée (figure 5), la saillie interne (2) du tube cylindrique (1) peut ne pas être sur toute la circonférence mais, répartie sur trois ou quatre points.According to a variant illustrated (Figure 5), the internal projection (2) of the cylindrical tube (1) may not be on the entire circumference but, distributed over three or four points.
L'injection terminée, il suffit à l'utilisateur de tenir, avec sa main libre, le tube cylindrique (1) et de le pousser jusqu'à ce que la saillie interne (2) de ce tube cylindrique épouse la gorge (7) de la seringue (figure 4).Once the injection is complete, the user just has to hold the cylindrical tube (1) with his free hand and push it until the internal projection (2) of this cylindrical tube matches the groove (7) syringe (Figure 4).
Ce système bloque la seringue à ce stade, il ne permet pas une réutilisation de celle-ci et, il protège l'utilisateur d'éventuelles blessures.This system blocks the syringe at this stage, it does not allow it to be reused and it protects the user from possible injuries.
Le dispositif selon l'invention est destiné au domaine médical.The device according to the invention is intended for the medical field.
