Results: bd received one sample unit for evaluation by our quality engineer team.
Upon examination, the needle was observed to be partially retracted and damage was found on the grip and at the connection of the grip and the barrel.
The needle was repositioned and the button was pressed, the needle retracted unsuccessfully.
The defect was determined to have occurred during the manufacturing process.
During production, the plug probe and load barrel stations have the ability to become misaligned and produce the type of damage observed.
Proper personnel have been notified.
A review of the device history record could not be performed as the lot number was not provided.
The samples were visually and microscopically evaluated and the customer's indicated failure mode for safety mechanism failure during use was observed.
Functional testing was performed.
It was observed that when the needle was pushed and repositioned to the out position.
The button was depressed and the retraction was unsuccessful.
Conclusions: the defect needle retraction failure, as stated in the description of the complaint, was confirmed with the returned unit.
The returned unit displayed damage to the grip component.
Conclusion: root cause relationship of device to the reported incident: manufacturing.
Comment: the plug probe and the load barrel stations in zone 5 have the ability to become misaligned and produce the type of damage observed in the returned sample.
When there is a misalignment, the probe inadvertently contacts the edge of the grip and causes the damage observed in the complaint.
