ABSTRACT:
It is, therefore, an object of the present invention to provide a needle stick protection device. The device includes a housing shaped and dimensioned for positioning about a syringe with an attached needle. The housing includes a first housing member telescopically coupled to a second housing member. A locking member is associated with a first slot of the first housing member for selectively engaging a first detent to control positioning of the second housing member relative to the first housing member. The locking member includes a first lateral retaining recess formed within the first slot for seating of the first detent when the second housing member is in its forward most position, the first lateral retaining recess being circumferentially located along a side of the first slot. The needle may be selectively covered and uncovered by selective alignment of the first detent with the slot in manner permitting controlled motion of the first housing member relative to the second housing member. The locking member further includes a lateral locking recess formed along the slot and adjacent a second side of the spring biased lock arm opposite the first side of the spring biased lock arm, wherein the needle is permanently covered when the detent is positioned within the lateral locking recess.
