摘要：
A safety needle device is disclosed comprising a hub, needle cannula, housing, tether, retractable sleeve, locking member and spring element. The tether is slidably 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 between an initial position, retracted position and an extended position with respect to the housing, wherein the initial position partially exposes a distal tip of the needle cannula, the retracted position fully exposes the needle cannula, and the extended position fully covers the distal tip of the needle cannula.
