Abstract

LA INVENCION SE REFIERE A UN PROCEDIMIENTO Y A UN NUEVO DISPOSITIVO PARA LA SEPARACION DE FLUIDOS DE LA SANGRE TOTAL COMO MEZCLA DE LIQUIDOS EN COMPONENTES SANGUINEOS INDIVIDUALES DE DIFERENTE COLOR, LA CUAL ESTA EMPAQUETADA EN BOLSAS FLEXIBLES QUE ESTAN CONECTADAS ENTRE SI MEDIANTE TUBOS TRANSPARENTES A LA LUZ (6), FORZANDOSE A LOS COMPONENTES SANGUINEOS PARA QUE FLUYAN DE UNA BOLSA A OTRA, ESPECIALMENTE PARA LA SEPARACION DE UN CONCENTRADO DE TROMBOCITOS A PARTIR DE UNA CAPA LEUCOCITARIA, UTILIZANDO UNA UNIDAD FOTOMETRO (10, 18) ACOPLADA EN LA ZONA DE UN TUBO, EL CUAL CONTIENE UN EMISOR (10) Y UN RECEPTOR (18) PARA ONDAS ELECTROMAGNETICAS Y POR LOS QUE PASA EL LIQUIDO EN EL TUBO. COMO EMISOR (10) DE LA UNIDAD FOTOMETRO (10, 18) SE UTILIZA UN DIODO EMISOR DE LUZ, CON UNA RADIACION DE LONGITUD DE ONDA EN EL INTERVALO DE APROXIMADAMENTE 535 NM A 575 NM (VERDE A ROJO), PREFERENTEMENTE 565 NM O DE APROXIMADAMENTE 400 NM A 453 NM (AZUL), DONDE EL RECEPTOR (18) DETECTA MODIFICACIONES DEL COLOR DEL LIQUIDO, PRODUCIENDOSE UNA SEÑAL, LA CUAL SE DIRIGE A UNA UNIDAD INTERRUPTORA (16), A TRAVES DE LA CUAL PASA LA CONEXION ENTRE LAS BOLSAS LO QUE HACE DETENERSE EL FLUJO CUANDO SE ALCANZA UN LIMITE PREDETERMINADO.
