Abstract: An adapter for mounting on drug vial of various sizes to provide needleless access to the interior of each vial regardless of its size. The adapter includes sharpened cannula surrounded by peripheral sidewall. The peripheral sidewall includes an upper portion and a lower skirt flaring outward from the upper portion and terminates in a peripheral free edge extending beyond the sharpened end of the cannula to protect users from an accidental needle-stick. The sidewall includes plural equidistantly spaced projections extending radially inward to form a ledge also has slits extending upward from the peripheral edge of the skirt to enable portions of the sidewall including the projections to flex outward. By so doing the cap of the vial is enabled to pass between the projections and then return to a position wherein the ledge has inside diameter just slightly less than the outside diameter of the rim of the cap to releasably secure the adapter to the vial with the cannula piercing through the septum of the cap.

Abstract: A safety needle device including a right angled Huber needle and a protective shield. The protective shield includes a central hub having a passageway and a pair of wing members. The distal end of the needle projects out of the passageway perpendicular to the hub. Each of the wing members is a generally planar member mounted to the central hub so that each can be flexed from an open state, wherein they are generally coplanar with each other, to a closed state, wherein they abut each other with the distal portion of the needle disposed between them to enclose it. The wing members also include plural connectors for cooperation with each other to hold the wing members in the closed state.

Abstract: A safety Huber angled needle device including a right angled Huber needle and a protective shield. The needle has a distal end portion extending generally perpendicularly its proximal end portion and terminating in a piercing tip. The protective shield includes a central hub and a pair of wing members movably secured to it on opposite sides of the central hub. The central hub has a distal end, a proximal end and a passageway through which the proximal end portion of the needle extends so that the distal end portion of the needle projects out of the passageway perpendicular to the central hub. Each of the wing members is a generally planar member mounted to the central hub so that each can be flexed from an open state, wherein they are generally coplanar with each other, to a closed state, wherein they abut each other with the distal portion of the needle disposed between them to enclose the piercing tip.
