A patient was receiving therapeutic plasma exchange (tpe) using a prismaflex tpe2000 set ckt and a prismaflex control unit.There was reportedly no issue during the priming of the set.One hour into treatment, the customer noticed that blood was leaking from the prismaflex tpe2000 set ckt, at the level of the connection of the access line to the blood pump segment.The tubing was reported to be slightly torn at this level.There was reportedly no alarm generated by the prismaflex machine.Due to this event, the treatment was stopped and then restarted using a new prismaflex tpe2000 set ckt.Reportedly, this external blood leakage caused a blood loss of 1 to 2 ml.There was reportedly no injury nor medical intervention related to this event.No additional information is available.
