ABSTRACT:
A multi-use safety syringe has a retractable needle that retracts only when the user wants to retract the needle. The safety syringe has an internal moveable carriage that locks to an end cap with releasable locking elements. The safety syringe guards against premature retraction of the needle by requiring the simultaneous release of two releasable locking elements by the user. When the locking elements are released, the carriage is released. The released carriage slides backward within the barrel, retracting the needle within the barrel.
