Abstract
A reactor suitable for extracorporeal treatment of blood includes a conduit defining within itself a passage of generally circular cross section and wound in a plurality of concentric helices so as to generate a transverse double toroidal secondary fluid flow in a fluid passing through the conduit. A spacer means is provided about the conduit to separate adjacent helices and permit circulation of a heat transfer fluid around each helix of the conduit.
