ABSTRACT:
Each of a plurality of modules (A) have fitings (14) with automatically closed check valves (16) therein such that the interior of the module is sealed. The module is selectively interconnected with a sterilizer apparatus (B). Interconnecting tubing (60) selectively supplied liquid from a reservoir (30) to the module. A sterilant injection chamber (56) receives and punctures a sterilant ampule such that incoming water mixes with the sterilant concentrate forming a sterilant solution which is carried to the reservoir. A reservoir outlet valve (70) selectively permits the sterilant solution to pass from the reservoir through the interconnecting tubing into the module until the module and interconnecting tubing are completely filled. Thereafter, the reservoir outlet valve closes holding the sterilant in the interconnecting tubing as well as the module for sufficient duration to sterilize both. Concurrently, additional tap water is heated in the reservoir until it is sterile. Alternate means of sterilizing the rinse fluid may also be employed. Thereafter, the reservoir outlet valve is opened again and the sterilant solution is drained and rinsed from the module with the sterile water. An air pump (86), a heater (84), and a submicron sterilization filter (82) supply heated, sterile drying air through the reservoir, connecting tubing, and module to dry the sterilized device.
