ABSTRACT:
A lockable safety shield assembly for a prefillable syringe is provided. The design of the lockable safety shield assembly enhances pharmaceutical manufacturers' ease of assembling the various components as part of its filling or processing of the prefillable syringes in normal practice, while at the same time minimizes difficulties in mating parts made from different materials. A tube is placed around the outside surface of the syringe barrel and affixed thereto. A collar is provided on the tube adjacent the distal end of the syringe barrel. A safety shield is axially slidable over the tube between a retracted position, wherein the distal end of the piercing element associated with the prefillable syringe is exposed, and an extended position, wherein the safety shield is locked to the collar to protectively cover the distal end of the piercing element. The safety shield includes locking structure configured so that the shield can be easily fitted over the tube. The locking structure includes at least one deflectable arm provided on the body of the shield. The deflectable arm includes a proximal end deflectable towards the interior of the shield. A stop member is provided on the interior of a shield in spaced relation to the proximal end of the deflectable arm. A ring is axially slidable over the shield to deflect the arm towards the interior of the shield to activate the locking structure. The safety shield is slid distally by an end user such that the collar is lockingly retained between the stop member and the proximal end of the deflectable arm. The collar, the stop member, and the deflectable arm may be configured to provide tactile as well as audible indication of locking to the end user.
