PROBLEM TO BE SOLVED: To properly extract a quantity of liquid sterilant to be used in a sterilization process from a cartridge containing the liquid sterilant.SOLUTION: The liquid sterilant is extracted from the cartridge, and after the liquid sterilant passing through the passage way is detected, a gas is introduced into the passage way. According to the number of extraction operations performed to extract the liquid sterilant during a period from the introduction of the gas into the passage way until the liquid sterilant passing through the passage way cannot be detected, the volume of the passage way in a period from the extraction of the liquid sterilant until the detection of the liquid sterilant, and the quantity of liquid sterilant to be used in a sterilization process, the number of extraction operations to be performed to extract the quantity of liquid sterilant to be used in the sterilization process is determined.COPYRIGHT: (C)2015,JPO&INPIT【課題】 液体の滅菌剤が格納された容器から、滅菌処理で用いられる滅菌剤の量を適切に取り出すこと。【解決手段】 容器から液体の滅菌剤を取り出して、経路内を通る液体の滅菌剤を検出した後に、経路内に気体を導入し、当該気体を当該経路内に導入してから、経路内を通る液体の滅菌剤を検出できなくなるまでに滅菌剤の取出し動作を行った動作回数と、容器から取出され液体の滅菌剤が検出されるまでの経路内の体積と、滅菌処理で用いられる滅菌剤の量とに従って、当該滅菌処理で用いられる滅菌剤の量を容器から取出すために行うべき取出し動作の動作回数を決定することを特徴とする。【選択図】 図14
