Abstract
Abstract A stopper removal apparatus is provided having an elongated flexible hollow stopper removal member for removing a stopper form a medical container and having an open end and a closed end, the stopper removal member has an angled protective shield adapted to extend over a medical container stopper and to cover a portion of the medical container. A first flexible stopper gripping portion of the stopper removal member is connected to the angled protective shield and can be compressed onto the stopper for removing the stopper. A second flexible stopper gripping portion is smaller in size than the first stopper gripping portion and is connected to the first stopper gripping portion for gripping and removing a smaller stopper from medical containers, so that a person can remove a plurality of sizes of stoppers from medical containers with one size shielded stopper removal apparatus while being shielded from the contents of the medical container.
