CA 2059844

An intravenous infusion set and/or blood collection assembly is provided with a safety feature for covering the used needle with a simple movement. The assembly is comprised of a structure which is of very economical and simple construction, which allows for manual mounting, if required, but which may be formed and handled on a mass production line for rapid production, as required. The safety feature is a two-part shield which when placed in cooperating relationship, allows accommodation of a conventional unmodified blood collection needle and body including the usual handling wings. After use, the body with the needle are pulled rearwardly so that the wings do not need to be touched but moved through slots past an abutment into positive locking slots which prevent the body, wings and needle from moving out of the shield thereafter. The two-part shield may be connected by a living hinge and is comprised of a semi-rigid thermoplastic material which gives for passage of the needle body and wings from the use position to the locked position.

n fournit un ensemble pour perfusion intraveineuse et (ou) prélèvement de sang comportant un dispositif de sûreté qui permet de couvrir l'aiguille usagée par un simple mouvement. Le dispositif en question est de construction très simple et très économique, si bien qu'il peut se monter à la main, au besoin, mais aussi, pour une production rapide, il peut être fabriqué et monté en série. Le dispositif de sûreté est un étui à deux parties, lesquelles, lorsqu'elles sont mises en concordance logent l'aiguille et le corps de la seringue d'un ensemble de prélèvement sanguin ordinaire et non modifié, y compris les habituelles ailettes de manutention. Après usage, on recule la seringue et l'aiguille de telle façon qu'il n'est pas nécessaire de toucher les ailettes, celles-ci glissant par des ouvertures au-delà d'une butée puis dans des fentes de verrouillage qui les empêchent de sortir de l'étui. Cet étui à deux parties, qui peut être muni d'une charnière, est fait d'un plastique semi-rigide qui laisse passer la seringue et les ailettes de la position d'utilisation à la position de verrouillage.
