1. A drug storage and delivery device comprising:
- a reservoir containing a liquid,a vial containing a dry drug,first forcing means for forcing the liquid from the reservoir to the vial, via an established fluid connection, thereby causing the dry drug to become reconstituted,means for establishing fluid connection between the reservoir and the vial comprising at least two flow paths,primary valve means adapted to open or shut each of said at least two flow paths, andsecondary valve means adapted to restrict the flow direction in each of said at least two flow paths, whereinthe reservoir, the vial, the means for establishing a fluid connection between the reservoir and the vial, the primary valve means, the secondary valve means and the first forcing means form an integral unit.

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.

11. A method of mixing two substances in a drug storage and delivery device comprising a reservoir containing a liquid, a vial containing a dry drug and means for establishing a fluid connection between the reservoir and the vial, the method comprising of:
-
moving the reservoir and the vial towards each other, thereby establishing a manually operateable fluid connection between the reservoir and the vial, manually operating primary valve means to establish fluid connection from the reservoir to the vial in a flow direction from the reservoir to the vial only, forcing liquid from the reservoir into the vial, thereby causing the dry drug to become reconstituted, manually operating primary valve means to establish fluid connection from the vial to the reservoir in a flow direction from the vial to the reservoir only, thereby allowing reconstituted drug to return to the reservoir, and actively or passively operating primary valve means to a position where fluid connection between the reservoir and the vial in any flow direction is shut, thereby preventing flow-back of the reconstituted drug from the reservoir to the vial.
