<p>A portable apparatus which produces high temperature and pressure steam derived from a microwave energy source for the rapid sterilization of medical and dental appliances. Items to be sterilized are placed in a detachable high pressure chamber (12) which is then attached to the microwave powered steam source (10). Microwave energy is then coupled into a guiding structure (34) containing a shaped impedance transformation element (37) so that essentially all of the microwave energy is transferred to a reaction fluid (24) contained in a holder (26) at the end of the matching transformation element (37). The reaction fluid is rapidly vaporized and the resulting vapors rapidly expand into the chamber through a metal screen (46) that also prevents the transmission of microwave energy. Pressure temperature values internal to the chamber are used to control application of microwave power thereby maintaining an optimum micro-organism kill condition for a prescribed time interval.</p> |
