A safety needle device comprising: a hub having a proximal end configured to be coupled to a syringe, the hub having a needle cannula extending therefrom in a distal direction, the needle cannula having a longitudinal axis and distal tip; a housing having a proximal end, a distal end, and a housing body, the hub being attached to the housing and the distal tip extending past the distal end of the housing; a needle cannula cover comprising an elongate sleeve having a distal end, the needle cannula cover slidably moveable in a distal and proximal direction inside the housing and being biased to move in a distal direction toward the distal tip of the needle cannula, the needle cannula cover being fixed relative to the housing to prevent rotational movement of the needle cannula cover with respect to the housing, the needle cannula cover having an initial starting position at which the distal tip of the needle cannula is exposed, an intermediate position at which the needle cannula cover is moved in a proximal direction to move the distal end of the needle cannula cover a distance further from the distal tip of the needle cannula, and an extended position at which the distal end of the needle cannula cover extends past the distal tip of the needle cannula to cover the distal tip (144; an activation component slidably engaged with the needle cannula cover and positioned intermediate the housing and the needle cannula cover, characterized in that the activation component being rotationally moveable with respect to the housing, such that when the activation component is moved rotationally when the needle cannula cover is moved in a proximal direction from the initial starting position, the needle cannula cover is activated and biased to move in a distal direction; the needle cannula cover has an opening at the distal end that permits the needle cannula to slide therethrough, and the device further comprises a clip disposed adjacent the distal end of the needle cannula cover, the clip preventing exposure of the distal tip of the needle cannula when the needle cannula cover is in the extended position; the housing includes a first ledge that cooperates with at least one radial protrusion on the activation component to maintain the activation component and the needle cannula cover in the initial position; and when the needle cannula cover is moved from the initial position in a proximal direction, the activation component is rotated, causing the at least one radial protrusion to move off of the first ledge, and causing the needle cannula cover to be moved in a distal direction towards the extended position. a hub having a proximal end configured to be coupled to a syringe, the hub having a needle cannula extending therefrom in a distal direction, the needle cannula having a longitudinal axis and distal tip;
