Abstract
An automatic injector separately stores liquid and dry components in respective compartments. When the injector is activated, a fluid-directing member between the liquid and dry compartments causes the liquid component to form a vortex as the liquid flows into the dry compartment. This allows the two components to combine more thoroughly and quickly to form a liquid solution that is delivered to an injection site.
