Device/batch history record could not be evaluated as the lot number is unknown.Observations and testing: received a stopcock valve attached to an extension set.The valve had a q-syte (top only) attached (bonded).Visual/microscopic evaluation: the septum was of 16 mold cavity.Severe damage (tear) was observed on the slit or the top disk.The top septum disk was unglued from the rim of the q-syte residual septum material and adhesive was observed on the rim of the top body.Damage (tear) was observed on the column wall damage (tear) was observed on the bottom disk slit (unit was disassembled after water/leak test).Water leak test (mm-110): attached the iso standard luer from the water leak test to the end of the ext.Set where the q-syte unit was bonded, no leakage was observed on the un-actuated position.Leakage was observed when the unit was tested in the actuated position, the source of the leakage was the tear on the top of the septum.Damage was observed on the slit of the septum top, bottom and column wall and the unit leaked when it was tested in the actuated position, the source of the leakage was the tear on the top of the septum.Root cause for this incident is indeterminate.A definite source that contributed to the tears (top-bottom slits and column wall) could not be established.The damage is normally attributed to 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 on a monthly basis.If the trend of a specific type of complaint warrants a formal corrective action, resources will be assigned at that time.
