Claim:
A needle device comprising: a housing having a base for placement against a surface of a needle-penetrating site, the base including a first opening; a needle mounted for a movement between a retracted position in the housing and an extended position, a portion of the needle extending through the first opening in the extended position; an actuator movably mounted to the housing and movable between a primary unactuated position in which the needle is in the retracted position, an actuated position in which the needle is in the extended position, and a secondary unactuated position in which the needle is in the retracted position; and a retraction mechanism, in direct contact with the site surface when the base is placed against the site surface, that automatically moves the actuator to the secondary unactuated position responsive to releasing the base from the site surface, wherein the actuator is not movable between the secondary unactuated position and the actuated position when the base is placed on the site surface.
