The event involved a single transpac® it monitoring kit w/ 104" red stripe tubing where it was reported that during patient use, the pressure head of the arterial catheter broke from its holder, so there was no longer any arterial catheter in full noradrenaline relay.This required a quick change of tubing.There was no significant delay in therapy.The blood loss was not significant.The medical intervention was the tubing was quickly changed.There was no physical defect noted prior use.There was patient involvement but no adverse event or human harm.

D9 - date returned to mfg on 10/5/2023.Received one used.List #011-0j729-01, single transpac® it monitoring kit w/ 104" red stripe tubing; lot #unknown.--> one (1) used.List #unknown, baxter viaflo chlorure do sodium 0,9% 1000 ml intravenous bag; lot #22k01e9s.Received sample photos.The reported complaint of transpac broken was confirmed.Two images were provided by the customer showing the involved device.During visual inspection, the blue housing around the transducer was found separated, exposing the wires of the transpac and the white wire was found separated from the transducer.The blue housing was not returned for evaluation.No plastic deformations or visual anomalies were observed on the returned sample.Representative samples were fixed to a mount and the tensile strength was measured using the instron.The separation was able to be recreated by connecting the transpac to a mounting bracket and then pulling the white cable at a 90deg angle away from the transpac.Seven (7) out of 30 tested samples pulled apart, exposing the wires of the transpac.However, after conducting an engineering study on this as a potential failure mode, it was determined that this was not the likely cause of the separation as this pulling force on the cable was more likely to lead to the transpac pulling out of the mount and not the reported complaint of the blue housing separating.A probable cause of the separation cannot be determined at this time.
