The invention provides a syringe and a method for using the same. The syringe includes a housing having a reservoir disposed therein and a plunger to be received by the reservoir, the plunger being moveable between a first plunger position and a second plunger position. The syringe also includes a plunger spring to urge the plunger toward the second plunger position and an actuator to deploy the plunger spring. The syringe also includes a needle proximate the distal end of the housing displaceable from a first needle position to a second needle position, and a shroud coupled with the housing. The shroud is moveable between a retracted position and an extended position, the shroud surrounding at least a portion of the needle when in the extended position. The syringe also includes an interlocking assembly, a shroud spring, and a locking assembly configured to inhibit movement of the shroud.
