The following information has been updated: d.10 device available for eval?: yes d.10 returned to manufacturer on: 2022-05-25 h.6 investigation summary: our quality engineer inspected the sample and photographs submitted for evaluation.Bd received one used q-syte unit.Additionally, four photos were received for investigation.A gross visual inspection determined that the septum was pushed in.Further microscopic inspection found that adhesive residue was present along the entire rim of the top body and on the underside of the top disk, indicating that adequate adhesion of the septum had been achieved during manufacture of the device.During manufacturing, low bond strength (or insufficient adhesive), septum misorientation, damage to the top body of the q-syte, and damaged tooling may result in the septum being pushed in.Operator-controlled checks for bond strength and septum damage are performed to mitigate the risk from this type of defect.Additionally, preventative maintenance (pm) is performed to ensure tooling is replaced per the quality plan and the equipment is functioning properly.Pm records could not be verified as no lot number was provided.During use, a pushed in septum can occur due to excessive actuations and extraneous force.Given that the sample was returned in a used state, this scenario cannot be ruled out.Although the reported issue was confirmed, it could not be determined if the damage resulted from the manufacturing of the device or from the user environment.Complaints received for this device and reported condition will continue to be tracked and trended.Information will be captured on trend reports and monitored.Our business team regularly reviews the collected data for identification of emerging trends.The complaint of a partially detached septum was confirmed but the exact cause was unknown.The physical sample was returned, in addition to four customer-provided photographs.The photographs indicated the same sample state as observed in the returned sample.Evaluation of the returned sample concluded that adequate adhesive coverage had taken place during manufacture, and no potential cause for the partially detached septum was observed.
