The investigation has been completed and the results are following.A nurse reported that the pelvic pack could not be opened.An arjo representative who answered the call advised to cut the strap in order to open the pelvic proning pack.There was no injury in relation to this event.The faulty bed was returned to arjo service center where buckle, a faulty component, was replaced.A service technician who inspected the bed found that the red button from the buckle was broken and would not release.This would indicate a mechanical failure of the buckle.Before the bed was released to the customer it went through quality process on 29 july 2019 in order to ensure the bed is in working order and ready for next rent.No anomalous condition was detected.It is unknown when and how the buckle became broken.While reviewing complaints for the last 5 years we have found 8 complaints regarding buckle inability to open due to mechanical issue.To sum up, when the event occurred the device failed to meet its performance specification since buckle could not be opened due to mechanical failure.The device was used for patient treatment during the event therefore was directly involved in the event.
