Abstract
A thermal fumigator is disclosed which vaporizes a drug in order to fumigate a space. The drug is vaporized by heat generated when the vapors of a volatile fuel come in contact with a metal catalyst. The fumigator includes a fuel container, a metal catalyst and a compressed mat, impregnated with a drug, which are held at fixed distances from each other for maximum efficiency.
Claims18
A thermal fumigator for the vaporization of a drug, comprising:
- a fumigator case having a gas passage formed therein;
- a fuel receptacle disposed within a lower portion of said fumigator case;
- a volatile fuel within said fuel receptacle;
- a support member mounted within said fumigator case above said fuel receptacle, said support member comprising a catalyst retaining part and a metal catalyst retained within said catalyst retaining part, said metal catalyst being located at a first predetermined distance above an upper surface of said fuel receptacle, and a heat radiating plate located at a second predetermined distance above said metal catalyst;
- and
- a mat supported by said heat radiating plate, said mat being impregnated with a vaporizable drug;
- wherein vapors rising from said volatile fuel contact said metal catalyst and generate a heat of reaction which is transferred to said heat radiating plate, whereby said mat is heated and said drug is vaporized.
