Person in charge stopping possible safe shielded assembly body null for pre-fill possible injector

摘要

(57) capable of engaging the safety shield assembly of the [summary] pre-fillable syringes are provided. At the same time makes it easier to assemble as part of the drug manufacturer is treated or filled with a pre-filled syringes in the usual way the various components, the design of the lockable safety shield assembly, different to minimize difficulties when aligning the parts made of material. It is attached to the outer tube and the tube is disposed on the outer surface of the outer cylinder of the syringe. I is provided in the tube collar adjacent the end of the syringe barrel. And a retracted position in which the exposed ends of the piercing element that is associated with a pre-filled syringes, safety shield is locked to the color, the safety shield of the tube in between the extended position covering can protect the ends of the piercing elements and can slide in the axial direction at the outside. The safety shield is provided with a locking structure which is a form that can be so easily attached to the outside of the shield tube. Latching structure includes an arm deflection of at least one provided in the main body of the shield. Arm has a proximal end that can flex inwardly of the deflection shield. Against the proximal end of the arm, the stopper member is provided inside the shield in spaced relationship deflection. Ring Operating the locking engagement structure bent toward the inside of the shield arm to slide in the axial direction of the outer shield. The safety shield to be held engageable in color between the proximal end of the flexure arms and the stopper member can be slid distally by the end user. The color, the arm may be in the form of displaying aurally and sensuously that locked against the end user and the deflection stopper member.
