摘要:
The present disclosure relates to a safety needle assembly that includes a syringe and a safety mechanism. The safety mechanism includes a housing defining an internal cavity, a shield member at least partially disposed within the internal cavity, and first and second locking members that are configured to selectively engage and maintain the shield member in one or more predetermined positions. The locking members are movable between a locked position, in which the locking members are in engagement with the shield member to substantially prevent axial movement thereof, and a release position, in which the locking members are disengaged from the shield member to permit axial movement thereof. The first and second locking members each include biasing members. The biasing member of the each locking member is positioned to cooperate with the other locking member to normally bias the locking members towards the locked position.
