D9 - date returned to mfg on 8/9/2023.Received the following: - one used unit.List #011-h2457, 25 units of spiros® closed male luer; lot #11379844.- one (1) used.List #unknown, connector; lot #unknown.- one (1) used.List #unknown, 3 way stopcock with extension tubing; lot #unknown.- one (1) used.List #unknown, connector; lot #unknown.- one (1) used.List #unknown, 20 ml bd plastipak syringe; lot #unknown.- one (1) used.List #unknown, 60 ml syringe with cytarabine; lot #unknown.It was observed and confirmed that a single used 011-h2457 spinning spiros was broken at the ultrasonic weld.The female portion of the spinning spiros remained attached to a large 60ml luer lock syringe while the body and male portion of the spinning spiros remained attached to an unidentified stopcock assembly.The ultrasonic weld was examined and the energy directors had good melt and penetration around the circumference of the weld.The energy directors fractured which is a sign of a good weld.The probable cause of the spinning spiros untrasonic weld breakage is typical of unintentional bending forces applied during use.The device history report (dhr) for lot 11379844 was reviewed and there were no relevant non-conformances found that would have contributed to the reported complaint.
