Abstract:
A sterilization apparatus, comprising:a) a sterilization chamber within which objects to be sterilized are placed;b) a tank within which water is held;c) a first conduit extending between the tank and the sterilization chamber;d) a heat source operatively coupled with the first conduit for converting the water within the first conduit to steam, said steam being directed into the sterilization chamber by the first conduit to sterilize the objects within the sterilization chamber;e) a measuring means for measuring a predetermined amount of water from the tank, said measuring means being operatively coupled with the first conduit for directing said predetermined amount of water from the measuring means into the first conduit, said predetermined amount of water being sufficient once converted to steam and directed into the sterilization chamber to completely sterilize objects placed in the sterilization chamber;f) a control means operatively coupled with the first conduit for causing the first conduit to direct steam into the sterilization chamber not more than a single time during the process of sterilizing the objects placed in the sterilization chamber;g) a second conduit operatively coupled between the sterilization chamber and the tank, said second conduit operatively directs water from the sterilization chamber back to the tank;h) said measuring means further comprises a measuring tank which receives a predetermined amount of water from the tank which is converted into a predetermined amount of steam by the heat source and is directed to the sterilization chamber by the first conduit;i) a first valve operatively positioned between the water tank and the measuring tank, and a second valve operatively positioned between the measuring tank and the sterilization chamber, said first valve being opened and the second valve being closed by the control means, before a particular sterilization process has begun such that the measuring tank is allowed to fill with a predetermined amount of water, and said first valve is closed and the second valve is open by the control means throughout the entire sterilization process such that the water in the measuring tank is converted to a predetermined amount of steam which is directed into the sterilization chamber.
