Qn#: (b)(4).The batch card(s) for the complaint lot(s) was reviewed and all passed qa inspections.1 actual sample and 4 representative samples were returned for investigation.Visual inspection showed the funnel was snapped from the shaft.Close review of the funnel section on actual sample revealed a remnant of x ray line inside the funnel lumen.Such a phenomena is likely to indicates rough or extreme force applied to the catheter which had caused shaft to snap.Such extreme tensile strength may exceed the standard requirement of the catheter strength which rendered the catheter to be detached or broke.Further test to review the funnel-shaft detachment force was conducted on the 4 representative samples via 1kg weight load test.Upon completion of the test period, all samples passed the test without funnel detached from the shafts.Nevertheless, as part of our initiative, positive released test was implemented at injection molding process.A maximum of 8 pieces of catheter from each batch were tested using weight load test during start and stop of injection molding process whereby 0.75kg (for catheter size ch6-ch10) and lkg load (for size 12ch and above) tested as per din en1616:1999 standard.This is to test the bonding strength between the funnel and tube.Batches that pass this test are subjected for release.Based on the evidence found in the investigation, the snapped catheter is likely been subjected to excessive force which caused product disfunctional.Therefore, this complaint could not be confirmed.
