Abstract
A shielding apparatus for preventing accidental contact with a sharp object such as a needle. The apparatus comprises a hinged shield, a barrel and a locking mechanism. The apparatus is attached to an existing needle via a barrel or may be manufactured into the base of the syringe needle. Connected to the barrel is a hinge, a shield and a locking mechanism. The shield may pivot, via the hinge, in a direction away from needle so as to expose the needle for use. Upon completion of the use, the shield is pivoted so as to cover the needle, the shield being either permanently or temporarily locked in place via the locking mechanism, thereby preventing accidental contact.
