An assembly of mains electricity (AC-powered) devices used to perform haemofiltration, a treatment whereby extracorporeal blood is slowly and continuously passed through a filter to allow for the removal of toxins and fluids, and/or the replacement of electrolytes. It typically consists of an extracorporeal blood pump circuit, tubing, catheters, solution mixer, and an operator's console with a monitor. The system functions with dialysate solution and a haemofilter for the transfer of substances by diffusion and convection (ultrafiltration).
