(EN) LEUKOCYTE FILTRATION METHOD AND APPARATUS
(FR) PROCEDE ET APPAREIL DE FILTRAGE DES LEUCOCYTES
Abstract
(EN)
A method for selectively removing leukocytes from a suspension which also contains platelets, such as a platelet concentrate or whole blood. The method includes passing the suspension through a filter which includes a polysaccharide-type coating. The coating may include one or more of hydroxypropylmethyl cellulose, hydroxybutylmethyl cellulose, dextran and hydroxyethyl starch. Also provided is a filter for selectively removing leukocytes from a suspension which also contains platelets. The filter includes a substrate which is coated with a polysaccharide-type composition.
(FR)
La présente invention décrit un procédé pour enlever sélectivement les leucocytes d'une suspension qui contient également des plaquettes, telle que des concentrés de plaquettes ou du sang complet. Le procédé consiste à faire passer la suspension à travers un filtre comportant un enduit de type polysaccharose. L'enduit peut inclure une ou plusieurs celluloses d'hydroxypropylméthyle, d'hydroxybutylméthyle, de la dextrane ou de l'amidon hydroxyéthyle. L'invention décrit également un filtre servant à enlever sélectivement les leucocytes d'une suspension contenant également des plaquettes. Le filtre comporte un substrat qui est enduit avec une composition de type polysaccharose.
