ABSTRACT:
Method and apparatus for rapidly sterilizing material including articles such as dental handpieces include introducing the article and liquid sterilant solution into a collapsible pouch formed of vapor-impermeable sheet material, sealing the collapsible pouch to form a gas-tight assembly, and vaporizing the liquid sterilant solution by heating it to produce an atmosphere of hot sterilant vapor. The liquid sterilant is introduced into the pouch in a quantity sufficient to create an overpressure when vaporized which is indicated by the collapsible pouch expanding to a distended condition. In one embodiment, the liquid sterilant solution is vaporized by irradiating the gas-tight assembly with microwave radiation in which case the material is sterilized under the combined effects of chemical vapor and microwave irradiation. In other embodiments particularly suited for sterilizing material comprising a plurality of articles, the at least one article is surrounded by shielding, which may be separate from or integrated with the pouch, and which may be provided on or in, i.e. as part of, the sheet material forming the pouch, which presents a barrier to the transmission of microwave radiation. The pouch containing the shielded article or articles and liquid sterilant is sealed and the gas-tight assembly is irradiated with microwave radiation to vaporize the sterilant whereupon the article or articles are sterilized under the effect of chemical vapor.
