Abstract
A method of sterilization for hospital and field use in which an article to be sterilized is submerged in water and ozone, which is supplied from a separate source, is bubbled through said water and over said article so as to provide an ozone concentration in excess of water saturation alone. Such a process can be used to kill even the most difficult bacteria and spores in shorter times than ethylene oxide sterilizers and further can be used for instruments which cannot stand steam temperatures or pressure changes.
Claims13
The method of sterilizing in which an article to be sterilized is submerged in water, and ozone from a separate ozone rich source is bubbled through the water and over said article while it is submerged thereby providing ozone concentration in excess of water saturation alone and releasing ozone from the water in the form of ozone filled bubbles which break in contact with said article and have a scrubbing action tending to dislodge surface contamination.
The method of sterilizing in which an article to be sterilized is submerged in water, and ozone from a separate ozone rich source is bubbled through the water and over the article while it is submerged, thereby providing ozone concentration in excess of water saturation alone and the submerged article is concurrently subjected to short bursts of ultrasonic vibration with dwell periods between bursts longer than the burst periods.
