In response to the event reported a device history review was conducted for lot number 1294476.Our records show that this is the only instance of this issue occurring in this production batch.According to the sampling plan applied for product performance, this lot was accepted and released without defects being noted during the final assembly or visual inspections.A sample could not be obtained for evaluation and testing; in lieu of the affected device, functional testing was performed on retention samples for this lot, the results of these show that the tested units performed within product specifications.Unfortunately without the ability to investigate the affected unit our quality engineers were unable to determine the root cause for this complaint.No actual sample and picture returned,the defect status could not be confirmed.Dhr review(lot#1294476): the complaint gauge was 24g,assembly at auto line 4 in nov.2021,packaging at cfs packing machine in nov.2021, lot quantity was (b)(4).Review the in process test and outgoing test reports for this lot product, all test results met the product specifications, no abnormal for it.Review the production records and machine troubleshooting records for this lot product,no abnormality, deviation or rework activity.Review incoming inspection records of catheter, no abnormality was observed.(the catheter for production of this lot was panel material, material number: b5171aaal, batch number:1088994/1088996/1088997/1028339/1055525/1055528) relevant functional tests of the retained sample from the same batch, please refer to the attachment for test report.Penetration force test was performed, the needle tip, catheter tip and catheter drag force were all within the product specifications.Lie distance was measured and no abnormality was found.According to the experience of previous market visits, it is suggested that customers should pay attention to the control of the initial puncture angle (15-30 degrees in principle) during the puncture process, which is conducive to feeding the catheter into the venous vessels.If the initial puncture angle is too low, the skin resistance to the catheter entering the venous vessels will increase, which may lead to the catheter peelback and puncture failure.No same complaint was received from the complaint lot.Conclusion(s) no abnormal found on process.As no defective sample returned, and the use status of the nurse was unknown, the root cause of the catheter peelback when the indwelling needle was put into the blood vessel could not be confirmed.
