ABSTRACT:
An apparatus (A) for sterilizing medical instruments and other articles includes a tray (12) with an article receiving area (14). An article to be microbially decontaminated is positioned in the receiving area (14) and a microbe blocking lid (10) is closed. A water electrolysis apparatus (30) receives water, splits the water into two separate streams that pass respectively through an anode chamber (34) and a cathode chamber (36), and exposes the streams to an electric field that results in the production of a catholyte solution for cleaning and an anolyte solution for sterilization. The anolyte and catholyte are selectively circulated through the article receiving area (14) by a pump (66) to clean and microbially decontaminate the external surfaces and internal passages of an article located therein. The anolyte or deactivated anolyte provides a sterile rinse solution. A reagent dispensing well (60) receives an ampule (80) or the like. The ampule (80) contains internal compartments which are selectively accessed or opened to dispense detergent concentrate and/or sterilant concentrate reagents into the circulating anolyte and catholyte solutions. A water treatment apparatus (28) dispenses either a salt or a cleaning agent into the water received from the source (24) to vary the electrolysis reaction or to form a cleaning solution to clean and flush the electrolysis apparatus (30), respectively.
