Process for checking the operation of sensors on a dialysis fluid circuit

摘要

The invention relates to a process for checking the operation of at least one sensor situated on a dialysis fluid circuit of an artificial kidney, consisting in: - circulating, in the extracorporeal blood circuit, a reference fluid of known characteristics, - carrying out a measurement, by means of the sensor (23) to be checked, of at least one characteristic of the dialysis fluid, - calculating, on the basis of the said measurement, the theoretical value of at least one characteristic of the reference fluid, - comparing the calculated theoretical value with the known value of the said characteristic of the reference fluid, - concluding, after the measurement has been made, that the sensor is operating correctly if the calculated theoretical value is substantially equal to the known value. The invention also relates to a device for applying this process. IMAGE
