Patent 7678073 was granted and assigned to Meridian Medical Technologies Inc. on March, 2010 by the United States Patent and Trademark Office.
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.
