This report is being supplemented to provide additional information based on the approved final investigation and device evaluation.The device history record was unable to be reviewed for this device since the serial number was not provided.However, olympus only releases products to market that meet all manufacturing specifications and final product release criteria.Based on the results of the investigation, the dirty water had accumulated inside of the water filter, the water filter turned brown, and had a faint, strange smell.The likely root cause of the dirty water was poor reprocessing.It is possible that the water filter clogged because it was not replaced, and that water was not properly removed.As a result, it is possible sufficient reprocessing could not be performed and the concentration of acecide decreased the instruction manual identifies the following verbiage, which may have prevented the phenomenon: ¿replace the water filter periodically, at least once in two months to prevent contamination of the rinse water.Replace the water filter at least once in two months.Otherwise, miscellaneous germs and stains in the water may contaminate the equipment and/or the endoscopes and prevent effective reprocessing.Disinfecting the water supply channel reduces the concentration of the disinfectant solution, making it unusable.Therefore, you are recommended to disinfect the water supply channel immediately before replacing the disinfectant solution.¿ olympus will continue to monitor field performance for this device.
