<p>The present invention is directed to a drug delivery device. The device (10) includes an interior chamber (150) and a seal structure (160). In accordance with the present invention, the interior chamber may include a first, liquid medicament compartment (151) and a second medicament compartment (152). The seal structure is conditionable to permit fluid to pass therethrough upon pressurization of the fluid. The seal structure preferably includes a sealing member (156) which moves from a first sealed position into a second by-pass position upon pressurization of the liquid injection solution in the wet compartment of the housing assembly. Such by-pass movement of the sealing member enables the liquid injection solution to flow through the seal structure into the second ingredient compartment and mix for injection.</p> |
