Investigation: the set was not available for investigation and we therefore conducted the following investigations based on the information provided.In the phlebotomy needle assembly process, the phlebotomy needle is assembled through the processes of bonding the cannula and hub, drying glue, inspecting the bevel of the needle by an image detector, and putting the protector over the cannula.Concerning the inspection by the image detector, the detector detects a collapse or a bend a\ the tip of which the size is 50 m.Any needles with such a collapse or bend are eliminated as defect.We reviewed the manufacturing record and inspection record of the reported lot number and no anomalies were observed in these records.In addition, the image detector is checked once a week for its accuracy.We confirmed that no abnormalities were observed in the detector checking which had been performed before and after the production of the product in question.We therefore think that the detector worked properly at the time of production.Phlebotomy needles are assembled in the environment with cleanliness control (grade c).We reviewed the related record and confirmed that any abnormalities relating to manufacturing environment had not been observed during the production of the reported lot number.The product in question is tested for the appearance of the needle tip and shaft on a sample basis.We reviewed the testing and inspection record of the reported lot number and its adjacent lot numbers.All the test items revealed no abnormalities and satisfied the standards.We examined one set of the retained sample of the reported lot number for penetration resistance.We confirmed that the results satisfied the standards.Regarding the reported lot number, we investigated whether any complaints had been reported.We confirmed that complaints had not been reported by any other customers as of (b)(6) 2020.Root cause: we were not able to identify the cause of the issue since we did not see any abnormalities in the manufacturing record, testing and inspection record, or retained samples.In the product, we did not find any factors that could have been related to the occurrence of the event.
