Abstract

In order to achieve continuous purification of blood in a simple manner, the invention proposes a method and a device for the extracorporeal purification of blood, waste products and serum being filtered out of the blood in a first step of the method and a suitable amount of serum being fed in metered fashion to the blood concentrate produced in this way in a second step of the method, which is characterised in that the filtrate obtained from the first step of the method is purified, its volume is reduced, and this purified filtrate is added to the blood concentrate in the second step of the method. <IMAGE>
