H.6.Investigation summary: 515568-zat and the product listed on the individual packaging were recognized in the photo.This product was 515568-zat as well as individual packaging.The specifications of this product did not differ between the 515540-zat and 515568-zat, except for the inner and outer diameters of the tube.In addition, the production number and production record confirmed that the packaging and sterilization processes for these two items were performed on the same date and time.Therefore, it was estimated that this event was caused by the product being mixed due to some mishandling of the workers after bagging, and shipping with the label check omissions overlapped.Since there was no abnormality in the production record, it could not be determined whether this event was only one or 515568-zat was not mixed with 515540-zat.We decided to collect the product number that had been packed and sterilized.If a mis-packed product was used without being aware of it, it could result in a different infusion volume from the intended flow rate.As measures to prevent recurrence, we identified items with similar appearance and started source management that separated production dates by three days or more.In addition, an inspector was assigned to confirm that the product is the same product using the product name and serial number on the label immediately before packing.H3 other text : see section h.10.
