Abstract

An automatic and self-locking safety device for pre-filled glass or plastic syringes of 0.5-3 ml in volume is made in one piece with a cylinder (1) to receive the barrel of the syringe (20), sprung vanes (12, 12b) and a clip (13b) for the plunger, fitted with a reinforcing stirrup (3, 3b, 4). The vanes are convex in shape to enhance their spring effect, and the clip has a cross-shaped slot (2) for the plunger stem. As the injection is administered the cylinder slides along the barrel and makes contact with the skin, the vanes bend as the plunger is depressed, and the cylinder covers the needle as it is withdrawn.

Dispositif de protection automatique, auto- bloquant en une seule pièce pour seringues verre prê-remplies  Automatic protection device, self-locking in one piece for pre-filled glass syringes

La présente invention concerne un dispositif de protection automatique, auto-  The present invention relates to an automatic protection device, self-

bloquant en une seule pièce pour seringues verre pré -remplies de O,5ml à  blocker in one piece for pre-filled glass syringes from O, 5ml to

3ml, pour certaines applications de seringues plastiques.  3ml, for certain applications of plastic syringes.

Actuellement, il n'existe pas de protection automatique des seringues verres après usage comme il n'existe pas de protection automatique de  Currently, there is no automatic protection of glass syringes after use as there is no automatic protection of

seringues abandonnées sur lavoie publique.  syringes abandoned on public roads.

Le risque de contamination est donc très important et connu. Pour le moment, seuls les conteneurs, les brise-aiguilles, et les dispositifs complexes  The risk of contamination is therefore very high and known. For now, only containers, needle breakers, and complex devices

semi-automatiques existent.semi-automatic machines exist.

Dans le cadre des seringues en verre de O,5ml à 3ml, la plupart des fabricants les produisent en rendant solidaires l'aiguille et la seringue. En conséquence, les utilisateurs, lorsque l'injection est terminée, n'ont pas d'autre recours que de se débarrasser de la seringue sans protection, alors qu'elle peut avoir été contaminée. Malheureusement, le maniement de cette  In the context of glass syringes from 0.5ml to 3ml, most manufacturers produce them by joining the needle and the syringe. Consequently, users, when the injection is finished, have no other recourse than to get rid of the syringe without protection, when it may have been contaminated. Unfortunately, the handling of this

seringue "usagée" se fait fréquemment dans l'urgence.  "used" syringes are often done in emergencies.

L'urgence est à la source de nombreuses piqures accidentelles; "37" de  The emergency is the source of many accidental bites; "37" from

grande gravité ont eu lieu en France en 1997.  serious events took place in France in 1997.

Le dispositif selon une première caractéristique comprend une partie cylindrique dans laquelle le corps de seringue circulera et se montera 0D librement. La longueur de ce cylindre sera limité par la taille du corps de seringue. Le dispositif présente selon une autre caractéristique deux parties flexibles, appelées lame-ressort, qui prolongent la partie cylindrique et serviront de  The device according to a first characteristic comprises a cylindrical part in which the syringe body will circulate and mount 0D freely. The length of this cylinder will be limited by the size of the syringe body. According to another characteristic, the device has two flexible parts, called leaf-spring, which extend the cylindrical part and will serve as

::,5 matiquement l'aiguille. Par ailleurs, le dispositif selon une autre caractéristique possède sur chaque lame-ressort une dent -accroche qui permettra 1' auto-blocage, ainsi qu'une charnière sur chaque lameressort, offrant à celles-ci la capacité de se plier Selon une autre caractéristique, les lame-ressort ont une forme convexe vers l'intérieur. Cette forme les oblige à se remettre dans cette position après l'injection. -2- 1 Le dispositif selon une autre caractéristique, montre à l'une de ses extrémités en continuité des lame- ressort; un clip fermé par deux crochets et un étrier de solidification. Par ailleurs, le clip en se fermant, laisse apparaître une lumière  ::, 5 matically the needle. Furthermore, the device according to another characteristic has on each leaf spring a hooking tooth which will allow one self-locking, as well as a hinge on each spring spring, offering them the ability to bend. According to another characteristic , the leaf springs have a convex shape towards the inside. This form forces them to return to this position after the injection. -2- 1 The device according to another characteristic, shows at one of its ends in continuity of the leaf spring; a clip closed by two hooks and a solidification stirrup. In addition, the clip by closing, lets appear a light

Le dispositif selon une autre caractéristique est constitué d'une seule pièce. Le dispositif selon une dernière caractéristique est fabriqué dans une matière injectée ou moulée, constituée de plastique,voire de fibre de verre qui  The device according to another characteristic consists of a single piece. The device according to a last characteristic is made of an injected or molded material, consisting of plastic, even fiberglass which

Quand au piston qui permnet l'injection, il se trouve enserré dans la lumière en  As for the piston which allows the injection, it is contained in the light in

Lors de l'injection, l'aiguille pénètre la peau, et sous la pression du pouce, le pistop et le dispositif descendent. Tout d'abord, le cylindre à son tour touche la peau et se bloque contre son extrémité. Alors que le piston continue à être prèssé, la seule possibilité pour les lame- ressort est de se contracter vers l'extérieur, aidées en cela par les charnières. En fin alO d'injection, l'utilisateur retire l'aiguille et les ressorts se déplient et obligent le  During the injection, the needle penetrates the skin, and under the pressure of the thumb, the pistop and the device descend. First, the cylinder in turn touches the skin and locks against its end. As the piston continues to be pressed, the only possibility for the leaf springs is to contract outwards, aided by the hinges. At the end of injection, the user withdraws the needle and the springs unfold and force the

cylindre à couvrir automatiquement l'aiguille.  cylinder to automatically cover the needle.

Tandis que les repose-doigts du corps de cylindre se bloquent dans les "dents-accroche".  While the finger rests of the cylinder body are locked in the "teeth-grip".
