The rapid infuser, ri-2 was tested by belmont medical technologies service department in the uk and the fault was replicated.Follow up with the user facility revealed that the ri-2 device was plugged into a 20 amp ceiling pendant system along with the following devices: anaesthetic machine, cell saver, pc, and syringe pump.This is not in accordance with belmont's instructions for use.The operator's manual provides ac input voltage requirements and instructs the user, "plug the system power cord into a dedicated-grounded, 3-prong, 20 amp, ac receptacle." the manufacturing records for this serial number were reviewed and no anomalies were identified.It was reported that another belmont rapid infuser was used to complete the case without further issue, no patient injury was noted.The ri-2 has been returned to belmont's manufacturing headquarters in the us for further testing.A follow-up report will be submitted upon completion of the investigation.

The rapid infuser, ri-2 involved in the incident was returned to belmont for investigation.Evaluation of the device revealed that the driver board was shorted and damaged, which damaged four power transistors and caused the system circuit breaker to trip.In addition, it was noted that the display was damaged and the back of the housing was dented, suggesting that the unit 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, however a definitive root cause of the damaged transistors cannot be established.Follow up with the user facility revealed that at the time of the incident, the ri-2 was plugged into a 20 amp ceiling pendant system along with the following devices: anaesthetic machine, cell saver, pc, and syringe pump.This is not in accordance with belmont's instructions for use.The operator's manual provides ac input voltage requirements and instructs the user, "plug the system power cord into a dedicated-grounded, 3-prong, 20 amp, ac receptacle." the use of the ceiling pendant system rather than a dedicated mains outlet can result in the circuit breaker tripping in theatres as reported, and is the reason for providing specific ac input voltage and ac receptacle requirements in the operator's manual.Belmont indicates that the system should be used on a dedicated line, as the system can draw a significant fraction of the circuit capabilities, and if the line is shared, the sum total of any two devices even when operating correctly, can cause the theatre breakers to trip.The conclusion reached is that this is an isolated incident which occurred due to a failure to follow the instructions provided in the operator's manual regarding ac input voltage and ac receptacle requirements for use of the ri-2 device.The manufacturing records for this serial number were reviewed and no anomalies were identified.The user facility indicated that another belmont rapid infuser was used to complete the case without further issue, there was no patient injury reported.Belmont will continue to monitor and trend similar reports of this nature and take further action if required.
