The following fields were updated due to additional information: d10: device available for eval: yes.D10: returned to manufacturer on: 22-may-2023.H6: investigation summary: our quality engineer inspected the sample and photographs submitted for evaluation.Bd received one used q-syte unit with no product documentation to indicate the reference or lot number.The photos are representative of what was returned and do not provide any additional evidence that isn¿t already covered by the physical sample evaluation.A gross visual inspection of the returned unit found that a portion the septum top disk was pushed in.Further inspection found that the portions of the top disk where the septum was not pushed in were still properly adhered.The unit was microscopically inspected.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.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.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, 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.A device history record review showed no non-conformances associated with this issue during the production of this batch.
