Patent ID: 7628781

Claim:
A connection assembly for transferring a fluid, particularly a fluid containing active products, from a reservoir to a medical delivery device comprising: a first connection element associated with the reservoir and comprising first retaining means and a reservoir interface; a second connection element associated with the medical delivery device and comprising a medical delivery interface and second retaining means capable of cooperating with the first retaining means to form an irreversible connection between the two elements; wherein the first and second connection elements further comprise a perforator capable of piercing a medicine vial, which is reversibly connectable to standard connectors allowing fluid transfer therethrough before an irreversible connection is made with the other element, the respective retaining means is positioned between the perforator and the respective interface; and wherein the first and second retaining means are arranged such that they cooperate with each other by clipping during a single translation movement of one connection element with respect to the other to make the connection irreversible; and wherein each perforator is aligned in the same direction at the time of the irreversible connection.
