Abstract
The invention relates to a filtration unit for enabling the selective leucocytapheresis of a fluid containing blood platelets. The filtration unit includes an external pouch provided with an inlet orifice and an outlet orifice, the pouch enclosing a porous element interposed between the orifices. The porous element encloses a leucocytapheresis medium impregnated with a polymer, the polymer having the general formula -(A)m-(B)n- (I), wherein A is a unit originating from an alkoxyalkyl acrylate or alkoxyalkyl methacrylate monomer, B is a unit originating from a hydrophobic polymerisable monomer, and m and n are integers, the sum of which, m+n, is equal to 100, m being an integer greater than 80.
