PROBLEM TO BE SOLVED: To provide a cleaning method and cleaning apparatus that can effectively remove blood or saliva in a brief time and reduce as much variation as possible in cleanliness of an instrument caused by the number of the instrument in which to put the cleaning apparatus, or how to be put in and disposed with respect to the medical instrument to which the blood or saliva are attached.SOLUTION: The method is disclosed for cleaning the medical instrument, wherein the medical instrument to which a body fluid adheres is subjected to ultrasonic cleaning in a cleaning liquid in which chlorine dioxide is dissolved. Also the cleaning apparatus includes: a cleaning bath 2 that is configured so as to be able to perform ultrasonic cleaning a mixing unit for producing the cleaning liquid in which the chlorine dioxide is dissolved a first pipe 4 for supplying the cleaning liquid from the mixing unit 3 to the cleaning bath 2 and a second pipe 5 for supplying water to the cleaning bath 2. The cleaning apparatus is configured such that the cleaning liquid supplied from the mixing unit 3 through the first pipe 4 is diluted with water supplied through the second pipe 5, so that the chlorine dioxide dissolved in the cleaning liquid is at a predetermined concentration in the cleaning bath.COPYRIGHT: (C)2012,JPO&INPIT【課題】血液や唾液が付着した医療器具に対して、洗浄機内に入れる器具の数量や入れ方・配置が原因となる洗浄後の器具清浄度のばらつきをできる限り無くすことを可能にした、血液や唾液を効果的に短時間のうちに除去できる洗浄方法および洗浄装置を提供する。【解決手段】体液が付着した医療器具を二酸化塩素を溶存する洗浄液中で超音波洗浄する医療器具の洗浄方法、ならびに、超音波洗浄し得るように構成された洗浄槽2と、二酸化塩素が溶存する前記洗浄液を生成するための混合部3と、前記混合部3から前記洗浄槽2に洗浄液を供給するための第1の配管4と、前記洗浄槽2に水を供給するための第2の配管5とを備え、洗浄液中に溶存する二酸化塩素が洗浄槽内で所定の濃度となるように、第1の配管4を介して混合部3から供給された洗浄液を、第2の配管5を介して供給された水で希釈するように構成された洗浄装置。【選択図】図1
