It was reported that the system could not be stopped when aspirating by the foot pedal.An angiojet ultra system console was selected for a venous thrombectomy procedure.The first part of the procedure was normal.After aspirating for 80 seconds, the foot pedal was released to prepare to stop aspiration.However, at this time, the system could not be stopped and it was still in running status.The keyboard was not responding, so the physician tried to shut down the system with the power button.The system was restarted and it changed the language from chinese to english and showed that the foot pedal was on.The console display showed: change the language.At this time only the power and alarm reset could be used.Then the physician changed the language and clicked "ap" after which the console showed "the aspiration volume 200cc, start the aspiration when the foot petal was off." the system could not be used and was shut down again.After one hour, the physician restarted the system.The system automatically switched to the priming procedure and showed an error message to "connect the saline supply." the pump cabinet could not be opened and the catheter could not be removed.After two hours, the physician restarted the system and the system automatically ran.The pump cabinet was opened and the catheter was removed.After the catheter was removed, the system displayed a message that said "illegally installed the catheter." the physician shut down the system and no further actions were taken.The procedure was not completed due to this event.There were no patient complications and the patient condition was noted as stable.
