Abstract: A drug storage and delivery device (1) comprising a reservoir (102) containing a liquid, a vial (101) containing a dry drug, such as a lyophilized drug, means (110) for forcing the liquid from the reservoir to the vial, via an established fluid connection, and valve means (106-108) to ensure a tight fluid connection between reservoir and vial can be established before the fluid paths are opened.

Abstract: A drug storage and delivery device (1) comprising a reservoir (2) containing a liquid, a vial (3) containing a dry drug, such as a lyophilized drug, means (6) for forcing the liquid from the reservoir (2) to the vial (3), via an established fluid connection, and locking means adapted to prevent the means (6) for establishing a fluid connection from re-establishing a previously disconnected fluid connection between the reservoir and the vial. Thereby the dry drug is reconstituted, and the forcing means (6) may subsequently be used for forcing reconstituted drug out of the device (1). The reservoir (2), the vial (3), the fluid connection and the forcing means (6) may form an at least substantially integral unit. This is an advantage because the number of steps needed to be performed by the user is reduced, the risk of contamination is reduced, the risk of incorrect reconstitution and dosage is reduced, and the device is easy to operate, e.g. using just one hand.
