A syringe including a barrel (14), a retractable needle (12) and a plunger rodassembly (22) including inner (30) and outer (24) members with a stopper (46)for expelling fluids from the syringe is disclosed.

The stopper is configured to compress asufficient amount when advanced distally in the barrel to cause the activationelement to engage and cause retraction of the needle within the syringe.
