It was reported that the centrifugal pump was leaking during patient treatment.The pump was investigated by the getinge laboratory on 2021-03-10.During visual inspection a crack at the upper pump housing was detected.No further damages were noted.If during connection of the tube to the pump too high forces are applied material damages in the form of cracks or fractures can be caused.These can then lead to the described leakage during use due to further external influences (e.G.Temperature, cleaning agents, mechanical impact).The production records of the affected rf-32 centrifugal pump (dms# (b)(4)) were reviewed on 2021-01-12.According to the final test results, all pumps passed the tests as per specifications.Production related influences can be excluded.Based on the investigation results the reported failure "leakage" could be confirmed.The most probable root causes is a mechanical damage caused by external influences (high forces, temperature, cleaning agents, mechanical impact).The occurrence rate was calculated for the reported failure and it was determined that this is not a systemic issue.Therefore, no remedial action is required.The occurrence rate related to the reported issue is currently being monitored as part of maquet cardiopulmonary¿ s trending program and additional investigations or corrections will be implemented in case of adverse trending.
