Abstract

The present invention relates to a device making it possible to protect the users of medical syringes from the risk of injury by contaminated needles. It consists of a slit conical slide with circumferential elasticity mounted on the body of the syringe, and capable of moving telescopically, thus preventing any contact with the tip of the contaminated needle after taking blood or an injection.

Description

SERINGUE DE SECURITE POUR PRISES DE SANG ET INJECTIONS
La présente invention concerne les dispositifs de protection de la pointe des aiguilles des seringues médicales pour prises de sang et injections comportant un coulisseau téléscopique tel que décrit dans le brevet français n 8708572. évitant lorsque l'aiguille est retirée de la veine ou du muscle le risque de blessure de l'utilisateur.SAFETY SYRINGE FOR BLOOD TAKING AND INJECTION
The present invention relates to devices for protecting the tip of the needles of medical syringes for blood tests and injections comprising a telescopic slide as described in French patent n 8708572. avoiding when the needle is withdrawn from the vein or muscle the risk of injury to the user.

Dans l'invention, objet de la demande de brevet français n 8708572, la solution retenue conduit à la conception d'un mode d'accrochage du coulisseau sur la seringue par un système de clrclips nécessitant une gorge sur l'extrémité antérieure de la seringue difficile de réalisation car demandant une modification importante des moules de fabrication des seringues existants . L'invention ci-dessus désignée, apporte une solution simplificatrice conduisant en particulier à une modification nettement moins importante des seringues existantes.In the invention, which is the subject of French patent application No. 8708572, the solution adopted leads to the design of a method of attaching the slide to the syringe by a system of clips requiring a groove on the anterior end of the syringe difficult to carry out because requiring a significant modification of the molds for manufacturing existing syringes. The invention designated above provides a simplifying solution leading in particular to a significantly less significant modification of existing syringes.

L'invention ici proposée comporte un coulisseau téléscopique fendu conique à élasticité circonférentielle ( 1 ).Sur la seringue(6), est rapportée un bossage carré (2) de faible épaisseur, qui peut être fixé par collage par exemple, mais qui peut être également obtenu par moulage avec le corps de la seringue.Ce bossage peut être fixé au niveau du nez d'assemblage des aiguilles .The invention here proposed comprises a telescopic split conical slide with circumferential elasticity (1). On the syringe (6), is reported a square boss (2) of small thickness, which can be fixed by gluing for example, but which can be also obtained by molding with the syringe body. This boss can be fixed at the level of the needle assembly nose.

Ce bossage (2) représente le point d'accrochage du coulisseau sur la seringue.This boss (2) represents the point of attachment of the slide on the syringe.

Le coulisseau comporte une fente longitudinale (3) avec un créneau antérieur (4) et un créneau postérieur (5).The slider has a longitudinal slot (3) with an anterior slot (4) and a posterior slot (5).

La figure 1 représente le dispositif selon l'invention en position de pénétration de l'aiguille.Figure 1 shows the device according to the invention in the needle penetration position.

La figure 2 représente le dispositif, selon l'invention en position de protection de l'aiguille.Figure 2 shows the device according to the invention in the needle protection position.

La figure 3 représente le coulisseau sans la seringue.Figure 3 shows the slide without the syringe.

Les berges de la fente du coulisseau comporte une rampe (7) non parallèle entre le créneau antérieur (4) et le créneau postérieur(5). Lorsque l'on déplace le coulisseau ( 1), d'arrière en avant, les berges de la fente (3)s'écartent avec le passage du bossage carré( 2) avant que celul-ci ne retombe dans le créneau postérieur ( 5) provoquant le verrouillage du coulisseau ( 1 ) sur la seringue(6)
Le déplacement du coulisseau (i) est manoeuvré à l'aide de la collerette (8) qui porte une encoche semi-circulaire (9) autorisant par le maintien entre pouce et index et par une rotation vissante du corps de la seringue (6) le réarmement du dispositif à la position de pénétration de l'aiguille figure 1, l'aiguille souillée avant été recapotée le coulisseau étant position de protection de l'aiguille figure 2 . The banks of the slider slot has a non-parallel ramp (7) between the anterior tooth (4) and the posterior tooth (5). When the slide (1) is moved, from back to front, the edges of the slot (3) move apart with the passage of the square boss (2) before it falls back into the posterior slot (5 ) causing the locking of the slide (1) on the syringe (6)
The displacement of the slide (i) is maneuvered using the flange (8) which carries a semi-circular notch (9) allowing by the holding between thumb and index finger and by a screw rotation of the syringe body (6) resetting the device to the needle penetration position in figure 1, the soiled needle before being recapped, the slide being the needle protection position in figure 2.

La caractéristique du dispositif selon l'invention est d'être d'une simplicité sans égal et d'un maniement aisé, permettant une modification très élémentaire des seringues existantes.The characteristic of the device according to the invention is to be unequaled in simplicity and easy handling, allowing very basic modification of existing syringes.

Comme il va de soi, l'invention ne se limite pas au seul mode de mise en oeuvre de ce procédé, ni au seul dispositif pour sa mise en oeuvre, décrit ci-dessus à titre d'exemple, elle embrasse au contraire toutes les variantes sans pour autant sortir du domaine de l'invention. As it goes without saying, the invention is not limited to the only mode of implementation of this method, nor to the only device for its implementation, described above by way of example, on the contrary it embraces all the variants without departing from the scope of the invention.
