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.Field of SearchHaving guard on piercing conduit for protecting body entering conduitAnd used as conduit manipulator (e.g., foldable gripper wings, etc.) Cover or protector for body entering conduit movable axially relative to one another Means for securing conduit to body Body entering conduit axially movable within body piercing conduit while former is disposed in the body Body entering conduit axially movable within flexible protective sheath facilitating sterile insertion into body duct Removable cover or protector for body inserted conduit Having cover or protector for body entering conduit | |
