Abstract:
1. A single-use syringe comprising: a shield having a forward end; a barrel having a needle at its forward end, the needle having a forward end, the barrel being mounted for axial reciprocation within the shield between a rearward position whereat the needle is shielded and a forward position of the barrel whereat the forward end of the needle extends beyond the forward end of the shield by an axial direction, wherein the barrel is initially in the rearward position with the needle being shielded by the shield; and a locking member mounted on the barrel, and the barrel carries forward the locking member when the barrel is moved from the initial rearward position to the forward position, and wherein the locking member engages the shield at the forward position, and is dismounted from the barrel and is retained in a forward position by the shield as the barrel is returned to the rearward position, the dismounted locking member preventing subsequent forward movement of the barrel, and wherein the dismounted locking member has an axial length greater than the axial dimension between the forward end of the needle and the forward end of the shield when the barrel is in the forward position.
