The disclosure relates to a dialysis system comprising a dialysate side and a blood side. In particular, and for example, in some embodiments, a dialysis system is provided and comprises a dialyzer including and a blood filter configured to divide the dialyzer and dialysis system into a blood side and a dialysate side. The blood side includes a blood circuit comprising a blood pump, a blood removal line, a blood return line, and a blood return line valve (BRV). The blood removal line and blood return line converge to a single venous access line in blood communication with a patient. The dialysate side includes a dialysate fluid circuit comprising first and second pump chambers each having a plurality of respective valves configurable to enable or prevent fluid communication with both the dialyser side of the dialyser and a drain. Each of the first and second pump chambers are configurable, based on the configurations of the valves, to comprise a blood accumulation chamber.
The invention relates to a blood treatment device, in particular a device which can perform haemodialysis and haemodiafiltration procedures. This is achieved using an interconnected pump and valve arrangement which can be controlled to direct fluid across a dialysis membrane or parallel to said membrane depending on the type of processing required. This allows dynamic variation between modes of operation and treatment.
The invention relates to a dialysis machine capable of performing ultrafiltration without the need for a dedicated ultrafiltration pump. The system uses a pair of membrane flow balance pumps wherein the operation and/or the volume flow rate of the pumps can be modified during operation to bring about a net movement of dialysate either into or from the dialyser. The direction of flow of the dialysate in the dialyzer is reversible and the dialyzer can comprise two dialysate inlets, one at each end, and two dialysate outlets, one at each end.
