Title
(EN) SYRINGE WITH CANNULA-PROTECTING SHEATH AND SEALING CENTER ROD
(FR) SERINGUE AVEC UNE GAINE PROTEGEANT LA CANULE ET UNE TIGE CENTRALE D'ETANCHEITE
Abstract
(EN)
A syringe assembly is comprised of a plunger (12), a syringe barrel (14) having a cannula collar (34) at one end of the barrel and an interior chamber (36) within the barrel, a hollow cannula (38) secured within the syringe barrel collar (34) with the cannula (38) extending axially from the collar to its distal end, a bore (52) extending axially through the cannula (38) and the syringe barrel collar (34), a segment of the bore decreasing (e.g., tapering) in diameter as it extends in a direction from the proximal end (42) of the cannula (38) toward the barrel interior chamber (36), and a sheath (16) removably attached to the syringe barrel (14) and covering the cannula (38), the sheath (16) being affixed to a center rod (68) extending axially from the sheath into the bore (52) at the cannula proximal end and then sealing engagement with said segment of the interior bore (52).
(FR)
Une seringue est constituée d'un piston (12), d'un cylindre (14) de seringue ayant un collier (34) pour canule à une extrémité et une chambre interne (36). Une canule creuse (38) est tenue à l'intérieur du collier (34) du cylindre de seringue et elle fait saillie axialement depuis le collier. Un canal (52) traverse axialement la canule (38) et le collier (34) du cylindre de la seringue. Une portion du canal diminue en diamètre (se rétrécit) en allant de l'extrémité proximale (42) de la canule (38) vers la chambre interne (36) du cylindre. Une gaine amovible (16) est placée sur le cylindre (14) de la seringue et elle couvre la canule (38). Cette gaine (16) est fixée à une tige centrale (68) s'étendant axialement depuis la gaine et s'engageant dans le canal (52) jusqu'à l'extrémité proximale de la canule où elle vient se loger d'une manière étanche dans le canal interne (52).
