A hypodermic syringe and method of filling the syringe with an injection fluid. The syringe includes a fluid chamber for retaining an injection fluid and a plunger assembly for expelling fluid from the chamber. The plunger assembly includes a plunger slidably disposed in the fluid chamber for creating positive pressures to cause ejection of a fluid from the chamber and an actuator coupled to the plunger for movement of the actuator between a first position with the actuator released for movement of the actuator through the fluid chamber relative to the plunger and a second position with the actuator in cooperative engagement with the plunger for driving the plunger to create the positive pressures.
