Sterilizer

Abstract From the Canadian patent

STERILIZER, A sterilizer for hospital and field use uses ozone, water, and ultrasonic energy, which will kill even the most difficult bacteria and spores in shorter times than ethylene oxide sterilizers and which can be used for instruments which cannot stand steam temperatures or pressure changes. Because no pressure chamber or heat is required, the sterilizer is much lighter portable, and, cheaper. An article to be sterilized is suspended over a water bath through which ozone is bubbled the moist ozone, contacting the article. The article is then immersed in the water and subjected to ultrasonic vibration for short periods to dislodge the bacteria and improve water/article contact.
