Abstract
The present invention is directed to a shieldable needle device. The shieldable needle device includes a hub having a lever extending from an external surface thereof, and a needle cannula with a puncture tip extending from said hub. The hub is interengaged with a housing having a main body portion with the needle cannula extending through a forward opening therein, and a rearward extension with a longitudinal slot extending axially therealong between a forward slot end and a rearward slot end, such that the lever of the hub extends through the longitudinal slot and is locked at the forward slot end thereof. The housing also includes a tip guard within the main body portion which is axially movable along the needle cannula. The lever is radially movable with respect to a longitudinal axis of the needle device to unlock the lever from the forward slot end, and is axially movable toward the rearward slot end to cause axial movement and to thereby retract the needle cannula, with the tip guard protectively covering the puncture tip of the needle cannula.
