An ampule shield has a center tube with an upper end, and an outer tube extending coaxially with the center tube and attached to the center tube below the upper end of the center tube. The outer tube extends some distance beyond a lower end of the center tube. The outer tube is spaced from the center tube to provide a cylindrical space within the shield for receiving an ampule. A removable cap for attachment to a bottom of the outer tube is provided.
