    摘要: A spike adapter and blunt cannula spike adapter assembly comprises a spike adapter having a hollow chamber extending axially therethrough from a first body end to a second body end. The hollow chamber is adapted to receive and accommodate attachment with a blunt cannula therein. A spike shaft projects axially outwardly away from the adapter body second end and has a sharpened tip at a distal end. A spike cover is disposed over the spike shaft to cover the sharpened tip. The spike shaft includes a hollow channel extending axially therethrough that is adapted to accommodate placement of a blunt cannula shaft concentrically therein to allow the blunt cannula to access medicine containers having unslit septums or stoppers. The spike adapter body includes axially extending grooves that accommodate blunt cannula tongues therein to form a tongue and groove attachment therebetween. Notches project from surface portions of the adapter body disposed across the grooves, and are designed to engage blunt cannula tongues to lock the blunt cannula into the spike adapter. The adapter body includes surface portions that are diametrically opposed to the grooves and that are deformable in a radially inwardly direction to permit the elastic deformation of the adapter body to unlock the tongues from the respective notches.
