Conclusion: is based upon evaluation of user facility information & the returned photograph; based upon evaluation of the returned actual sample.
The actual device and a photograph has been returned to the manufacturing facility for evaluation.
The photograph inspection confirmed the reported complaint.
There were some air bubbles staying at two points on the upper area of the oxygenator module.
Visual inspection of the actual device revealed no anomalies or defects.
The actual sample was rinsed, dried and filled with saline solution.
With the blood-outside clamped, a pressure of 2.
0kgf/cm2 was applied from the blood-in side for 6 hours.
No leak occurred.
The actual sample was rinsed and dried again.
It was then built into a circuit with tubes and primed in accordance with manufacturer specification.
Neither entrainment of air or backflow of air from the purge line occurred.
Functional testing was conducted.
Abrupt priming of the actual sample at the flow rate of 7l/min.
Caused some air bubbles to remain inside the oxygenator module while the prime was flowing into the oxygenator module.
These bubbles were found to be difficult to remove when the circulation flow rate was insufficient.
A review of the device history record and the product release decision control sheet of the involved product/lot # combination was conducted with no relevant findings.
A search of the complaint file did not find any other report with the involved product code/lot# combination.
There is no evidence that this event was related to a device defect or malfunction.
