A safety needle device (10) for protecting a user against inadvertent needle- stick injury. This needle device includes a needle housing (18) having a distal housing opening (78). An arcuate groove (34) extends within the needle housing terminating adjacent the distal housing opening. A needle (16) is disposed within the arcuate groove having a distal needle portion (14) extending away from the needle housing through the distal housing opening. An elongate sheath assembly (12) surrounds the needle within the groove. A biasing member (82) is disposed within the needle housing and is configured to move the sheath assembly throughout the length of the arcuate groove and through the distal housing opening. The sheath assembly then completely encloses the distal needle portion.

Cette invention concerne un dispositif à aiguille de sécurité (10) destiné à protéger l'utilisateur contre des risques de piqûre accidentelle. Ce dispositif comprend un logement pour aiguille (18) présentant une ouverture distale (78). Dans le logement d'aiguille, une rainure courbe (34) vient s'achever contre l'ouverture distale dudit logement. Dans la gorge courbe se trouve une aiguille (16) dont la partie distale (14) traverse l'extrémité distale du logement. Un ensemble gaine (12) entoure l'aiguille à l'intérieur du logement. Dans ce même logement, un élément de contrainte (82) sert à faire se déplacer l'ensemble gaine sur toute la longueur de la rainure courbe et à travers l'ouverture distale dudit logement. L'ensemble gaine recouvre alors complètement la partie distale de l'aiguille.
