The initial failure description was that the rotaflow displayed the error message "battery error" during patient transport and the device is shutting down.A medical intervention was required.No harm to any person has occurred.A getinge service technician tested the affected rotaflow (serial# (b)(6)).The rotaflow was working as intended and the batteries have been replaced in (b)(6) 2021.It was found that the (uninterruptible power supply) of the hospital was causing the reported failure.The hospital has switched to not using ups any longer.The most probable root cause could be determined as the ups (uninterruptible power supply) which is used by the hospital.Based on these investigation results the reported failure could be confirmed.The product in question was produced in (b)(6) 2005.The review of the non-conformities has been performed on (b)(6) 2022 for the period of (b)(6) 2005 to (b)(6) 2021.It does not show any non-conformity in regard to the reported product and failure.There is no indication on manufacturing issues occurred during this time, thus production related influences are unlikely.Further mitigation are included in the instruction for use (ifu rotaflow| 4.3 | en | 14 ) as warnings in chapter 3.3.4 battery operation: check battery capacity every 6 months, at the latest.The battery must be replaced by the authorized technical service every 2 years, at the latest.The battery must be replaced sooner if it cannot be fully charged within 8.5 hours or if the system cannot be operated with the fully charged battery.The actual run time during battery operation depends on the age and condition of the batteries, current consumption of the rotaflow console and other factors.The run time shown is only a reference value.The actual run time can be shorter or longer.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.The occurrence rate was calculated for the reported issue and it was determined that this is not a systemic issue.Therefore, no remedial action is required.
