Abstract

Un filtro para remover de la sangre entera o de hemoderivados de sustancias entre las cuales se citan, no a título limitativo, leucocitos y plaquetas; dicho filtro comprende una estructura que contiene un cuerpo filtrante estratiforme, por lo menos un estrato de éste último está revestido en poliuretano; dicho poliuretano tiene un peso molecular comprendido entre 10.000 y 20.000 Dalton. Se reivindica también un método para la realización del cuerpo filtrante estratiforme para un filtro como el presente en el cual se prevé que por lo menos un estrato de dicho cuerpo se impregna de poliuretano mediante su inmersión en un contenedor de una mezcla en la que dicho poliuretano está presente. Dicha mezcla está constituida por una solución en la cual el poliuretano está disuelto en un solvente polar como el agua.
