Abstract

EL INVENTO ES UN DISPOSITIVO PARA MEDIR EL TIEMPO DE MODIFICACION DEL ESTADO FISICO DE UN MEDIO FLUIDO, DEL GENERO QUE COMPRENDE UN VASO VERTICAL CONTENIENDO EL FLUIDO Y LOS REACTIVOS NECESARIOS, Y EN EL CUAL ESTA COLOCADO UNA BOLA FERROMAGNETICA ATRAIDA EN ROTACION POR UN CAMPO MAGNETICO EXTERIOR. ESTE DISPOSITIVO SE CARACTERIZA PORQUE SU VASO (1) PRESENTA EN LA PARTE INFERIOR UN CAMINO DE RODADURA ANULAR (4) PARA DICHA BOLA (5) Y COMPORTA UN DISPOSITIVO DE DETECCION (17) QUE LIBERA UNA SEÑAL ELECTRICA, CADA VEZ QUE LA BOLA (5) PASA DELANTE DE EL, Y ESTA ASOCIADO A UNA UNIDAD DE MEDIDA (23) QUE DETERMINA LAS VARIACIONES DEL INTERVALO DE TIEMPO ENTRE DOS PASADOS CONSECUTIVAS DE DICHA BOLA (5). APLICACION PARA LA MEDIDA DEL TIEMPO DE COAGULACION DEL PLASMA SANGUINEO
