Abstract: An injection apparatus for administering an injectant includes a mixing chamber having an impermeable membrane disposed therein, a first chamber containing a dry component, and a second chamber containing a liquid component. The dry component and the liquid component combine to form a liquid injection solution in the mixing chamber. The mixing chamber is configured to retain the liquid injection solution formed by a combination of the dry component and the liquid component. The injection apparatus is selectively configured in a plurality of states including a storage state and a mixing state.
