Abstract
A vial adapter comprises an adapter body comprising a top wall and a sidewall projecting from the top wall in a longitudinal direction to form a receptacle with a distal side of the top wall. The receptacle is configured to receive at least a portion of a barrel head of an injection vial. A movable part comprises a base part and a spike fixed to the base part. The spike extends through the top wall in a distal direction into the receptacle. An actuating member is mechanically coupled to the movable part, and is movable relative to the adapter body from a start position to an end position along a first direction to induce a distally directed displacement of the movable part relative to the adapter body. The mechanical coupling between the movable part and the actuating member is releasable when the actuating member is in the end position.
