Abstract: A portable oral inhalator for use in a home, mobile vehicle and/or boat including a carrying case having compartments therein for compressor motor, dry cell batteries, switching controls, and medication. The inhalator provides optional control means therein for supplying 6 volt D.C. energy to the compressor motor, such as converting 110 volt A.C. power to 6 volt D.C. for home use, and 12 volt D.C. to 6 volt D.C. for vehicle or boat use, as well as a 6 volt D.C. dry battery source. The inhalator is useful in the treatment particularly for chronic asthmatics and other chronic pulmonary diseases.
