Additional information was added to d9, h3, h4, h6, and h10: h10: the device was received for evaluation.A visual inspection via the naked eye was performed, and a brown color particle embedded in the material of the tubing line was observed.The reported condition was verified.The particle was not in the fluid path because it was embedded in the material of the tubing line outside of the fluid pathway.A fourier transform infrared spectroscopy test was performed, and the particle was identified to be a mixture of polyvinyl chloride (pvc) and phthalate material which is the same material as the tubing.Fragment of burnt pvc (brown particle) can potentially be embedded in the material of the tubing during the manufacture of the tubing.Burnt pvc is a byproduct of the tubing material.Since the particulate matter was embedded (not in fluid path) and made of the same material as the tubing line, this is therefore a cosmetic condition.The cause of the particle was determined to be fragment of burnt pvc embedded into the tubing during the manufacturing process.A batch review was conducted and there were no deviations found related to this reported condition during the manufacture of this lot.Should additional relevant information become available, a supplemental report will be submitted.
