Abstract
An apparatus () for extracorporeal blood treatment comprising a blood treatment device () having a semipermeable membrane () which separates a blood chamber () from a fluid chamber (). A used fluid line () connects the fluid chamber to a used fluid discharge. A first pump () controls the ultrafiltration through the semipermeable membrane. A second pump () arranged in the used fluid line downstream of the first pump keeps pressure between the first and the second pump at a constant predetermined value. The invention provides a protection system against any possible pressure change in the used fluid discharge in a hemodialysis or hemo(dia)filtration apparatus.
