Method and apparatus for filling syringes with retractable needle

A syringe for receiving a fluid from a container. The syringe comprises a barrel for housing the fluid and including an end wall with an opening defined therein, a plunger for slidable engagement within the barrel, and moveable between a retracted position and an extended position, and a needle. The needle has a first end anchored to the plunger and a second distal end, a conduit defined by the needle, and an inlet offset from the second distal end for fluid communication with an opening defined at the second distal end. The plunger includes a plunger seal for engagement within the barrel, the plunger seal defining a passage for receiving the needle. The syringe further comprises an engagement system having a complementary feature to cooperatively engage with a complementary feature of the container to mount the container to the syringe.
