Event Description
|
A user facility biomedical technician (bmt) reported that a fresenius 2008t machine experienced a blank display and smelled smoke.Upon follow up, the bmt confirmed the reported event, stating the machine was pulled from the treatment floor due to a blank display.Additionally, the bmt initially thought the burning (or smoke) smell was coming from the card cage.However, after opening up the card cage they noticed a ¿buildup of molten plastic¿ underneath valve 105 (v105).The bmt confirmed the component had melted.After finding the damaged component, the bmt subsequently replaced it with a new part.The damaged valve was discarded and no photos of the component were available.No other parts exhibited any type of thermal damage.The bmt confirmed they were still troubleshooting the blank screen issue.No additional details are available at this time.The cause of the event is unknown.The bmt stated that the machine hours were unknown.The bmt confirmed that the machine has not had any past problems with failing the electrical leakage test prior to the event.The bmt confirmed that the machine was plugged into a hospital grade ground-fault circuit interrupter (gfci) outlet.The bmt confirmed that no patient was connected to the machine at the time of the incident and there was no harm to any patients or individuals because of this malfunction.
