Blood to be purified is passed through a haemofiltration element and a haemodialysis element in cascade and the ultrafiltrate output from the haemofiltration element is passed through a filter such as an activated carbon filter, preferably with uncoated activated carbon. The ultrafiltrate thus purified can then be used as a reinfusion solution to be readministered to the patient.

Blood purifying equipment particularly for the treatment of patients

Dialysis apparatus is provided of the type comprising a casing housing a central cylindrical core which is surrounded by a plurality of layers of capillary tubes constituted by hollow, semi-permeable, fibres. Blood to be treated is caused to flow through the capillary tubes while dialysing solution is passed over the outer surfaces of the tubes. To facilitate the construction of dialysis apparatus with different dialysing surface areas without altering the dimensions of the casing or core, the core is arranged to dismountably carry a plurality of spacing annuli around which the layers of capillary tubes are wound. The diameter of the annuli determines how many layers of capillary tubes can be accommodated in the casing.
