Patent attributes
Cap adapters for a medicament vial configured to facilitate the transfer of liquid medicament from the vial and into a syringe. In one embodiment the cap adapter comprises a wall portion with a first lumen passing through it. A vial-engaging portion secures the cap adapter to the vial. A spike extends from the wall portion and defines a second lumen passing through the wall portion. A cone-shaped shield extends from the first lumen. The shield is configured to guide a hypodermic needle toward the first lumen to thereby reduce a risk of needlestick to a user handling the vial. In certain embodiments, a light source cooperates with the cap adapter to illuminate at least a portion of the cap adapter to reduce a risk of needlestick to a user handling the vial in a darkened environment. In certain embodiments, a secondary sealing member abuts a first face of the wall portion and seals an end of the first lumen. In certain embodiments, a locking sleeve resists or prevents removal of the cap adapter from the medicament vial.
