Abstract
UN OXIGENADOR DE SANGRE QUE TIENE UNA ESTRUCTURA SUSTANCIALMENTE CILINDRICA PROVISTA CON UNA PARED INTERIOR (1) O NUCLEO Y UNA PARED EXTERIOR (2) QUE DEFINEN UNA CAMARA DE OXIGENACION. LA CAMARA DE OXIGENACION CONTIENE UN HAZ DE FIBRA HUECA (3) COMPUESTO DE FIBRAS SEMI-PERMEABLES MICROPOROSAS HUECAS QUE ESTAN DESTINADAS A SER AFECTADAS EXTERNAMENTE POR LA SANGRE QUE FLUYE EN LA CAMARA DE OXIGENACION. LA CAMARA DE OXIGENACION ESTA PROVISTA CON CONDUCTOS DE ENTRADA (7A) Y DE SALIDA (9A) PARA CONECTAR CON EL EXTERIOR. LAS FIBRAS HUECAS (3) ESTAN FIJAS, EN SUS EXTREMOS, EN ANILLOS DE RESINA DE POLIURETANO CONOCIDO COMO ENCAPSULACION, Y ESTAN CONECTADAS RESPECTIVAMENTE A LAS CAMARAS DE ENTRADA Y SALIDA DE GAS (6,8) PARA LA ENTRADA DE OXIGENO Y PARA LA DESCARGA DEL DIOXIDO DE CARBONO. LA ESTRUCTURA INCLUYE VARILLAS (10) QUE EXTIENDEN DESDE LA PARED INTERIOR DE LA ESTRUCTURA Y ESTAN DIVIDIDAS EN UNA PLURALILDAD DE CONJUNTOS (10) QUE SE DISPONEN LONGITUDINALMENTE A LO LARGO DE LA LONGITUD TOTAL DELNUCLEO GENERALMENTE PARALELAS CON EL EJE DEL NUCLEO (1) LAS VARILLAS (10) ESTAN ADAPTADAS PARA PRODUCIR UNA DISPOSICION EN EL HAZ DE FIBRA (3) PARA QUE EL HAZ DE FIBRA (3) TOQUE LA PARED EXTERIOR (2) DE LA ESTRUCTURA EN LAS REGIONES DONDE TOCA A LAS VARILLAS (10) Y PARA QUE EL HAZ DE FIBRAS (3) SE SEPARE DE LA PARED EXTERIOR (2) Y TOQUE LA PARED INTERIOR (1) DE LA ESTRUCTURA EN LAS REGIONES ENTRE LOS CONJUNTOS ADYACENTES DE VARILLAS (10).
