On february 22nd, 2021 was reported that 40 minutes before the end of a dialysis session, the blood pump of the dialysis machine surdial-x2-hdf-uj bearing serial number (b)(4) stopped without any alarm.According to the nurse, the machine stayed without blood pump functioning for 30 minutes.Therefore, the blood in the extra corporeal circuit coagulated both in the arterial and the venous side.As consequence, since the blood could not be re-infused, the patient lost around 300ml of blood and the treatment was completed on another machine.Furthermore, the main control board of the machine was replaced, but a noise from the speaker was heard and a damaged wire in the articulation of the screen was found.
