The production device history record (dhr) for this iabp unit was reviewed and no non-conformances related to the reported event were noted.A getinge service territory manager (stm) was dispatched to investigate and confirmed the reported issue and noted that the device was fully functional except for the battery operation.The stm reviewed the log files and found no electrical failure codes and verified batteries are not showing any data in the service menu.The stm replaced the power management board and made sure the harnesses were seated properly but the iabp unit still fails in battery mode.The stm returned the next day and replaced 2nd power management board, power supply assembly, executive processor board, backplane board, and front end board, but the iabp continued to fail with no battery function.The stm then investigated further and removed the power slot interface board and discovered saline residue under the power slot interface chassis and in between the chassis and the power slot interface board at the j4 connector.The stm reinstalled all original boards and cleaned and dried the saline residue out of the bottom of chassis.The stm noted there was no signs of saline that entered through the main unit.The stm then returned the next day and replaced the power slot interface board and reassembled the device for testing, but the iabp still remains operating on ac power only.The stm consulted with the customer and had the iabp unit brought to his office for further investigation and found that the j15 was not seated correctly.The stm repositioned, reseated and secured the j15 wire harness, and tested the device.The batteries were charging and the iabp unit was able to operate on the battery.The stm tested the iabp unit for a few hours without any further failures.The stm then performed all calibration, functional and safety tests per factory specifications and the iabp was returned to the customer and cleared for clinical service.
