Abstract

UN SISTEMA DE TRATAMIENTO DE SANGRE ANTITROMBOTICO QUE CONSTA DE UNA COMBINACION DE MEMBRANA DE FIBRA HUECA DE PERMEABILIDAD SELECTIVA QUE CONTIENE UN COPOLIMERO QUE TIENE UNA UNIDAD DE OXIDO DE POLIETILENO; UN COLECTOR QUE TIENE UNA SUPERFICIE DE CONTACTO DE SANGRE RECUBIERTA CON BIEN UN COPOLIMERO HIDROFILICO HEPARINIZADO QUE CONTIENE VINIL CLORIDO COMO SU PARTE CONSTITUYENTE O BIEN UN COPOLIMERO HIDROFILICO QUE TIENE UNA UNIDAD DE OXIDO DE POLIETILENO; UN CATETER; Y UN CIRCUITO. ELLO HACE POSIBLE POR PRIMERA VEZ CONDUCIR CIRCULACION EXTRACORPORAL DURANTE UN LARGO PERIODO DE TIEMPO SIN LA NECESIDAD DE ADMINISTRAR HEPARINA INTERNAMENTE IMPARTIENDO UNA PROPIEDAD ANTITROMBOTICA A TODA LA SUPERFICIE DE CONTACTO DE SANGRE.
