Low temperature sterilization and disinfections method and apparatus for medical apparatus and instruments
First Claim
1. A method of disinfecting and sterilizing medical apparatus/instruments at low-temperature, which comprises:
- immersing said apparatus/instruments in an aqueous liquid bath;
introducing aqueous liquid into said aqueous liquid bath and withdrawing aqueous liquid therefrom to effect washing of said apparatus/instruments and removal of desorbed microorganisms contaminates therefrom;
applying ultrasonic vibration at a predetermined frequency to said aqueous liquid bath and to said apparatus/instruments contained therein, said vibration being sufficient to effect a substantial desorption of said microorganisms contaminates from said apparatus/instruments;
introducing ozone into said aqueous liquid bath to oxidize said microorganisms contaminates; and
applying ultraviolet (UV) irradiation to said aqueous liquid bath and to said apparatus/instruments contained therein.

Abstract
A method and apparatus for the low temperature sterilization and disinfections to be applied to medical apparatus/instruments. This invention perfects the use of ultrasonic, UV, ozone in a liquid bath with at least one chemical reagent which can be either sterilant or disinfectant solution for reprocessing many classes of medical equipment/instruments especially those which do not withstand high temperature sterilization process and require sterilization or high level disinfections. The invented method can effectively remove and destroy contaminates, particularly living organisms, bacterial spores, virus, and organics from used or contaminated medical apparatus/instruments surface, inner hollow lumen tube, joints and crevices. Having greatest immediate application for the cleaning, disinfecting and sterilizing all in one simple process for reprocessing used or contaminated medical apparatus/instruments after treating patients.
