Abstract
To increase the safety of an extracorporeal blood treatment machine which has control of the ultrafiltration rate as a function of the blood volume of the patient, the ultrafiltration rate UFR(t) during the treatment is monitored in a safety device. The safety device has a computer unit for determining an upper limit for the ultrafiltration rate UFR from the predetermined total ultrafiltrate volume UFV and the predetermined treatment time UFT. The safety device also has a monitoring unit with which the ultrafiltration rate is limited to the upper limit determined by the computer unit so that any risk to the patient is prevented even in the case of faulty blood volume control.
