DEVICE AND METHOD FOR PREPARATION OF SUBSTITUTION SOLUTION

摘要

There is described a device for hemodiafiltration with a fluid balancing device and on-line preparation of the substitution fluid from dialysate by sterile filters. The preferred embodiment uses two sterile filters whereby the first filters the dialysate and the second is passed by the dialysate. This second sterile filter is arranged in the dialysate fluid circuit between the first filter and the dialyser in a positive pressure area, which is separated from the rest of the downstream dialysate circuit. Due to the positive pressure in the area of the second filter, the dialysate passes through the filter membrane and from there to the extracorporeal circuit via a line as substitution solution.
