The following fields were updated due to additional information: d10: device available for eval yes, d10: returned to manufacturer on: 2021-02-17 h6: investigation summary to aid in the investigation of this issue, the affected sample was returned to bd for evaluation by our quality engineer team.Through examination of the sample, the septum top disk component was observed separated from the top body of the q-syte component.The column of the septum is torn away.There is a visibly large tear at the septum column wall, which is indicative of leakage.During the manufacturing process when the septum slit is created, tears to the column wall may occur when the probe enters the slit due to a misalignment.Checks for alignment are performed during the preventive maintenance process.As a lot number was unknown for this incident, a review of the production history records could not be completed.Regular inspections are performed to test for septum leakage and damage, however, the observed degree of damage to the septum column is not normally seen during the manufacturing process.During the manufacturing process, septum misorientation or uneven deposition of adhesive may result in damage to the q-syte or septum detachment.Visual observations reveal residual adhesive deposits on the rim of the top body component, indicating that that a uniform bond was made at the time of manufacture.Damage was not observed to the top body nor were there signs of septum misorientation.It is possible that the observed damaged resulted from excessive actuations or extraneous force.The separation of the top disk can also result from extraneous force.It is possible that the septum column tear existed as a manufacturing defect and then was exacerbated through use, however, this cannot be confirmed.See h10.
