Abstract
A needle protector device comprising a protector tube slidingly disposed in an outer tube and slidingly disposed over a syringe comprising a needle, the protector tube comprising at least one abutment initially in engagement with the outer tube such that the protector tube is constrained from moving distally with respect to the syringe, a biasing device disposed inside the outer tube operative to provide an urging force on the protector tube in a direction that tends to urge the protector tube distally towards a tip of the needle, and a release mechanism operative to move the at least one abutment out of engagement with the outer tube upon distal pushing of a plunger of the syringe, such that when the at least one abutment is out of engagement with the outer tube, the biasing device urges the protector tube distally towards the tip of the needle.
