Investigation results: device/batch history record review could not be performed as the lot number was not provided.The peura (end user risk analysis) was analyzed to determine the risk to customer.The analysis showed that due to low occurrence, current risk is acceptable.One sample unit was received for evaluation by our quality engineer team.Upon examination, tears were observed on the top of the septum and the septum column.An air bubble test did not result in bubbles in either the actuated or un-actuated position.A water leakage test also did not confirm leakage in the actuated or un-actuated position.Conclusions: the defect air in line, as stated as the reported code was not confirmed with the returned q-syte unit.Although air in line was not confirmed, the presence of the column tear would contribute to the air in the line.Confirmed there were slit tears on the septum top and bottom disks.Root cause is indeterminate.A definite source that caused damage to the column wall; which could allow the air to be in the line, could not be established.The failure modes normally attributed to these types of damage are incorrect usage or excessive actuations.An instruction pamphlet is provided with q-syte product.This information documents the potential failure modes of this device if not used properly.A formal corrective action will not be initiated at this time.Customer complaint trends are evaluated monthly.If the trend of a specific type of complaint warrants a formal corrective action, resources will be assigned at that time.
