ABSTRACT:
A needle assembly includes a needle hub with opposite proximal and distal ends and a passage extending between the ends. The needle cannula has a proximal end mounted in the passage of the hub and a distal end aligned at an angle to the proximal end. Wings project transversely from the hub to facilitate a temporary affixation of the needle assembly to a patient. A safety shield is hingedly mounted to the hub and can be rotated from an open position spaced from the needle cannula so that the distal end of the needle cannula can be used to deliver a drug to a patient. The shield also can be rotated to a closed position where the distal end of the needle cannula is safely enclosed within the shield. Locking structure on the shield prevents re-exposure of the needle cannula.
