Abstract: A drug delivery device (1) for delivering fluid drug, preferably liquid drug. The device (1) comprises means for receiving and retaining a reservoir (5) containing drug. The retaining means (13, 14) is movable between a locking state, in which the reservoir (5) is retained, and an unlocking state, in which the reservoir (5) is released. Thereby drug from several reservoirs (5) may be delivered while the device (1) is operated using only one hand. Thereby the risk of displacing an infusion needle during change of reservoir is minimised. The device (1) comprises pumping means (3) for causing a flow of fluid in an established fluid connection. The drug delivery device (1) is preferably movable between an ‘aspiration mode’ and an ‘infusion mode’, most preferably automatically during insertion/release of a reservoir (5). This enables integrated (blood) aspiration, minimum waste of drug and minimum unintended infusion of air in the vein.

Abstract: A drug mixing device (1) comprising at least two vial holders (4), at least one reservoir holder and means for establishing fluid connections between the reservoir holder (2) and the vial holders (4). Each of the vial holders (4) is adapted to receive a vial (5) containing a dry drug, such as a lyophilized drug, and each vial holder (4) comprises a hollow spike (9) adapted to penetrate a septum of a vial (5). Each of the reservoir holder (2) is adapted to receive a reservoir (3, 21) containing a liquid. Liquid can be provided from reservoir (3, 21) to vials (5) via an established fluid connection in order to reconstitute the dry drug. Each of the spikes (9) is provided with a stopping member (11) adapted to be in a first position in which a fluid passage is allowed, and a second position in which such passage is prevented.
