ABSTRACT:
An improved safety device is provided for protecting medical personnel and the like against needle stick injuries and/or exposure to communicable diseases or other harmful agents. The safety device comprises an elongated protective sleeve supported by front and rear bearing members for sliding movement about a medical needle and its associated support structure, such as a support hub or barrel. The protective sleeve is slidable in a stable manner from a first position with the pointed end of the needle safely retracted within and shielded by the front bearing member to a second position with the needle projecting through and beyond the front bearing member for normal use. After use, the sleeve is slidable to a third position derailing the pointed needle end from the front bearing member, and exposing a visual indicator to indicate that the needle has been used. Closure flaps associated with the front bearing member positively prevent needle reinsertion through the front bearing member, and thereby prevent accidental or unauthorized needle re-use. Detent members interacting between the rear bearing member and the needle support structure releasably lock the protective sleeve in the various positions.
