description A safety needle device is disclosed having a hub, needle cannula, housing, tether, retractable sleeve, locking member and spring element. The tether is movably disposed in the housing, the tether having a slot with an enlarged first guide path and a narrowed second guide path extending distally from the enlarged first guide path. The retractable sleeve is configured to move from an initial position to partially expose a distal tip of the needle cannula, a retracted position to fully exposes the needle cannula, and an extended position to fully cover the distal tip of the needle cannula. The proximal movement of one or more protrusions on the retractable sleeve, rotates the tether to move the at least one or more protrusions from the enlarged first guide path of the tether to the narrowed second guide path of the tether, this rotation activating the device.
