Our product evaluation lab received one flotrac sensor with attached pressure tubing set and detached iv set.The customer report of a foreign material was found inside the iv tubing was confirmed.An unknown black material less than 0.5 mm x 0.5mm in size, was found in the iv tubing at 8.4 cm from the distal end of the iv set.Another unknown black material less than 0.5 mm x 0.5mm in size was found in the drip chamber.The materials did not move during 5 minutes of continuous flushing.After cutting out around the material area, it was confirmed that the materials were embedded inside the iv tubing wall and the drip chamber wall.The materials were sent to chemistry lab for further analysis.Regarding a black material embedded in the pressure tubing wall, the spectrum did not have a good match with anything in edwards library.Regarding a black material embedded in the drip chamber wall, it was too small to isolate it from the drip chamber wall.Therefore, it was unable to test.A device history record review was completed and documented that the device met all specifications upon distribution.An engineering evaluation was initiated to assess for any manufacturing-related processes which could be correlated to the complaint.There are manufacturing controls to avoid potential causes related to the malfunction of - iv tubing and catheter body contamination embedded in the components which are incoming sampling inspection, 100 percent visual inspection, manufacturing continuous monitoring sampling, and qa sampling inspection.As part of the execution of the engineering evaluation process, the inspection and specification criteria by type of contamination indicates that for embedded particles for a size of less than 0.05 mm2 and the maximum number of particles per 100 cm2, is unlimited.Since this size of embedded particle is accepted, it is not considered as a manufacturing defect.Product risk assessment and capa escalation were not required.
