Title: Improvement in methods and apparatus for sterilizing objects
Inventor: KUTNER BARRY S
IPC: B65D81/34
Filed: 1993-03-25
Abstract: An arrangement (10) for sterilizing objects (22) in which a quantity of liquid (20) and one or more objects to be sterilized are introduced into a pouch (16) formed of flexible sheet material at least partially transparent to microwave radiation whereupon the pouch is sealed to form a gas-tight assembly (14). The gas-tight assembly is situated in an inner rigid cavity (26a) of an enclosure which is at least partially formed of material that is substantially transparent to microwave radiation. The enclosure is irradiated with microwave radiation which passes into the cavity and then into the gas-tight pouch assembly situated therein to vaporize the liquid to produce an atmosphere of hot vapor under pressure in the pouch. The pouch expands under pressure until the sheet material of which it is formed presses against the rigid inner surfaces of the enclosure cavity. At least a part of the gas-tight pouch assembly may be surrounded with microwave radiation shielding (24) which divides the interior of the pouch into shielded (38a) and unshielded (38b) interior portions, the object to be sterilized being situated in the shielded pouch portion while the liquid to be vaporized is situated in the second unshielded pouch portion.
