  • Reason
    To date, three thermal events that led to fire have been reported in three separate machines; one during a disinfection cycle, and two prior to patient use when the machines were switched on. while there was damage to each of these machines, no patients or healthcare providers were injured as a result of these events. the occurrence of such events is low, with a rate of approximately 0.01% of formula machines manufactured since 1998. based on our internal investigations, we determined the battery charge board to be the source of two of the events. the source of the third event could not be conclusively confirmed due to the extent of the damage to the board, but the available evidence is consistent with the other two events. we have determined that disconnecting the battery charge board will eliminate the possibility of the failure mode while a permanent solution is implemented. .
