(b)(4).The batch card(s) for the complaint lot(s) was reviewed and all passed qa inpection.There is one actual sample returned for investigation.Based on complaint description it was stated that the catheter had broken at the funnel joint and the shaft.From a physical review on the sample return, there is no abnormality aside to broken area between the funnel and the shaft for the actual sample returned for investigation.The sample was subjected to magnification at 50x using dino-lite magnifying tools.It was determining the remnant of the shaft still intact in the funnel area.The end shaft where the broken occur present a jagged surface which suggesting there is either excess torsion or tensile force had been applied resulting the detachment of both.Catheter broke may occur due to various reasons such as catheter was in contact with sharp or pointed object, effect of clamper used, excessive force applied at the funnel end or between the shaft as a result of catheter stuck at crib rail or tube extended as the patient glide on the bed.Lt is also common for the patient to pull the catheter out of their bladder due to discomfort.Such extreme tensile or torsion strength may exceed the standard requirement of catheter strength and render the catheter to be detached or broke.Nevertheless, as part of our initiative, positive released test was conducted at injection molding process.As per spm-as1-002, maximum of 8 pieces of catheter from each batch were tested using weight load during start and stop of injection molding process.0.75kg load (for catheter size ch6-ch10) and 1kg load (for size ch12 and above) will be tested as per bs en 15020596:2018 standard.This is to test the bonding strength between the funnel and tube.Batches that pass this test are subject for release.It was observed the remnant of the shaft was present inside the funnel suggesting there is not a mechanical failure joint on the assembly.The jagged surface on the shaft end suggesting there is an external torsion or tensile that perhaps exceed the product maximum tensile force allowable per standard requirement.Therefore, this complaint could not be confirmed.
