Dhr review: the complaint lot# is 4234833, sku is 383313, assembly in suzhou plant on 2024.Sep.12, lot quantity is (b)(4) ea.Review the in-process test record and outgoing test report, all test results meet the product specifications, no abnormal found.Review the product assembly record, no non-conformities, deviations, or rework activities for this lot.Returned sample analysis: a picture was provided, and it shows the vent plug was removed and connect some other component, and the component was circled to describe a leakage point.Retain sample analysis: sampling 2 ea from the retain sample of the same lot to do leakage test, test result is within product specification.Possible cause analysis: based on the information, customer remove the vent plug, connect other component and circled the leakage point on the component.The possible reasons for this failure may including: 1.Luer port of the luer-adapter was damaged or have raw material defect.2.The third part component assembly status is not good after removing the vent plug.Current manufacture already has control procedures as below to monitor and prevent this kind of defect: 1.Both incoming inspection and in-process assembly will sample to monitor material quality.2.Both in-process and outgoing sampling check will do leakage test for component related to vent plug luer port.Conclusion: there is one picture provided but we cannot observe is there any defect on the luer port of luer-adapter, is also possible a poor third part component assembly issue by customer after removing vent plug.The retain sample leakage test result is within product specification, so the root cause is not clear for this leakage issue.
