(b)(4).Device history record (dhr): reviewed the device history record for batch number 19d14g8261 and there were no defect encountered during in process and final control inspection.Summary of root cause analysis: one used cannula of introcan safety-w pur 20g, 1.1x32mm-ap without packaging was received.Protective cap and catheter hub were not returned for evaluation.During visual inspection, no any dent mark or abnormality has been observed from the cannula surface of all cannula orientation and observed that the safety clip was dislodged.Review of device history record for complaint batch shows no abnormality.Final control visual inspection and safety clip functional test results for complaint batch were reported as passed.Safety clip dislodged is able to be simulated during cannula withdrawal in extreme angle and with faster speed.The simulation results are consistent with the complaint defect.According to ifu, during application user should remove the cannula by pulling cannula straight back with a controlled, continuous motion parallel to the skin and the cannula is advisable to be disposed of immediately into the sharps container.Therefore, root cause could not be determined.Clip dislodged most likely not appear to be attributed by the manufacturing process as our assembly machines are equipped with 100% inspection by the vision systems for the clip on all parts is available at assembly machine, it is unlikely that the defect escape from process.Along the whole manufacturing process, there are no interference/ contact between clip hole and cannula crimping area.Safety clip dislodged is able to be simulated by withdrawing the cannula in certain angle which is not following ifu.This report is being filed for an item number that is not sold in the united states, however similar items are sold in the united states by b.Braun medical, inc.
