The belmont rapid infuser, ri-2 was returned to belmont for investigation.The reported failure was not easily replicated, however after extensive stress testing the reported touch screen malfunction was confirmed.A definitive root cause could not be established, however upon receipt it was noted that various areas of the housing were cracked and the display panel was damaged, suggesting that the unit had suffered an impact.An impact of this nature may result in damage to internal components, either directly or by allowing fluid to enter the device.Fluid contamination can cause problems with the membrane switch/cpu board interface, however it is not possible to determine whether damage from the impact directly contributed to the reported unresponsive touch screen.The operator's manual cautions the user: "immediately wipe any spills from the device." the service and preventive maintenance schedule outlined in the manual instructs the user to check the unit seals every six months.The operator's manual also offers possible conditions and recommended operator actions in the event that the keypad is unresponsive or does not accept input.The manufacturing records for this serial number were reviewed and no anomalies were identified.It was reported that there was no injury to the patient.Belmont will continue to monitor and trend similar reports of this nature and take further action if required.
