The rapid infuser, ri-2 has not been returned to belmont for investigation.The user facility was unable to provide the specific serial number of the ri-2 involved.Following receipt of the hospital's report, belmont's sales representative went to the hospital and conducted a field test on the functionality of the four ri-2 units in the emergency department (serial numbers (b)(4)); all four units performed according to specification.Without the ability to investigate the unit, we are unable to confirm the report that the prime and infuse screens became overlaid upon one another.A review of the manufacturing records for all four serial numbers indicated that one unit (serial number (b)(4)) was returned to belmont in december 2020 for a non-functional touch screen, which was traced to damage caused by saline contamination.Fluid contamination can cause problems with the membrane switch/cpu board interface and contribute to touch screen issues which may resolve once the fluid has dried.The operator's manual provides instructions for routine maintenance to prevent damage to the membrane switch and cpu board interface caused by fluid contamination.The service and preventive maintenance schedule outlined in the manual instructs the user to check the unit seals every six months and cautions the user: "immediately wipe any spills from the device." the troubleshooting guide in the operator's manual also provides possible conditions and recommended operator actions in the event that the keypad is unresponsive or does not accept input.Should additional information become available, a supplemental report will be provided.
