A drug delivery system includes an automatic injector that can deliver a small, precise amount of a therapeutic agent. The automatic injector includes a chamber for containing a liquid component and a thin porous member that carries thereon and/or therein the small, precise amount of therapeutic agent. Upon activation of the automatic injector, a flow path opens from the chamber through the porous member, enabling the liquid component to rapidly mix with the therapeutic agent before being injected.

Case for an injection device

The present invention is directed to an automatic injection device containing a pre-loaded charge of medicament for automatically self-administering the medicament upon actuation thereof. The automatic injection device includes a dry compartment located within a housing for storing a predetermined dry charge of the medicament therein, a wet compartment within the housing for storing a predetermined amount of liquid injection solution therein, an activation assembly for causing the liquid injection solution in the wet compartment to be transferred to the dry wet compartment, and at least one compression assembly for maintaining the medicament located in the dry compartment under a continuous compressive state as the liquid injection solution passes through the dry compartment.
