Abstract

Compact units for kidney machines or similar artificial organs pref. using membranes of types disclosed in FR. 2043917 (made of 'Teflon' (RTM), a thin rubber sheet or pref. aluminium) with closely controlled porosity ranges in the region of pref. 100-1000 A to allow construction of integral separation, exchange and blending units without risks of cross contamination compared with use of conventional cellulosic membranes. Cross or back flow interaction may be induced by differential (centrifugal) pressure effects or by electro-osmosis. Pref. cellophane membranes are used in conjunction with membranes of controlled porosity.
