Title (EN) RETRACTING NEEDLE SYRINGE
(FR) SERINGUE A AIGUILLE RETRACTABLE
Abstract:
(EN) The syringe has a re-use prevention feature where the plunger rod (26) and needle hut (38) are destroyed and the needle (64) is retracted into the rod. This feature requires only an increase of force along the same line of action as the injection stroke. This allows for safe, one-handed injection, which is critical in some situations. The syringe also minimizes the amount of wasted medication because the plunger rod tip (28) occupies the entire volume inside de the barrel (20). The retracting needle syringe uses standard luer-lok fittings and can be used with a variety of standard needles that do have rectracting cannula. A large gauge needle can be used to fill the syringe from a vial or other container before attaching the savety needle for injection. Lastly, the plunger can be completely encapsulated by the barrel prevents re-use of the syringe and allows for safe and easy disposal.
(FR) Cette seringue est pourvue d'un dispositif interdisant une réutilisation, en l'occurrence, la tige support du piston (26) et l'embout de l'aiguille (38) sont détruits et l'aiguille (64) se retire dans la tige. Cet agencement, qui n'exige que l'application de davantage de force le long de la même ligne d'action que celle de la course d'injection, permet de procéder en toute sécurité à une injection d'une seule main, ce qui est essentiel dans certaines situations. Cet agencement permet également de réduire la quantité de produit médicamenteux gaspillé et ce, dans la mesure où la pointe (28) de la tige support du piston occupe tout le volume du cylindre (20). Il est possible d'utiliser cette seringue à aiguille rétractable qui fait appel à des systèmes de raccordement Luer-lok normalisés avec diverses aiguilles classiques pourvues d'une canule rétractable. Il est possible d'utiliser une grosse aiguille indicatrice pour remplir la seringue dans un flacon ou tout autre récipient avant de fixer l'aiguille de sécurité pour procéder à une injection. Le piston est, en dernier lieu, entièrement encapsulé par le cylindre, ce qui interdit la réutilisation de la seringue et permet de la jeter facilement et en toute sécurité.
