Per the investigation, it has been confirmed that the full featured wallstand latch on the drx evolution system was working as intended.The tech thought that the grid was latched and rotated it 90 degrees for the exam.The grid fell out of the bucky causing the patient injury.Typically when the grid is inserted into the bucky an audible "click" is heard by the tech.This "click" indicates the grid is properly latched and the bucky can be rotated 90 degrees.In this instance, evidence shows that the grid was believed to be latched already based on the visual appearance of the grid in the bucky so an audible "click" was not heard.The drx evolution's console and system monitor also has a visual indicator which provides confirmation of grid presence in the bucky.This visual indicator can be used as a secondary verification to ensure the grid is properly inserted.In this instance, neither the primary indicator (click) nor the secondary (console/monitor indicators) were used to verify the proper latching of the grid before rotating 90 degrees.Carestream has concluded this investigation and therefore a follow up is not required.Since this device (s/n (b)(4)) was manufactured prior to udi requirements only a s/n is recorded.
