Abstract

APARATO PARA EL SUMINISTRO DE DIALIZADO DE UN SOLO PASO. EL APARATO UTILIZA UN PAR DE CILINDROS EQUIPADOS CON DIAFRAGMAS HIDARULICAMENTE ACCIONADOS Y CON UN METODO PARA CONTROLAR LOS DIAFRAGMAS Y EL FLUJO DE DIALIZADO RESULTANTE A UN HEMODIALIZADOR Y DESDE UN HEMODIALIZADOR DURANE LA HEMODIALISIS. LOS DIAFRAGMAS HIDRAULICAMENTE ACCIONADOS DEBEN SINCRONIZARSE DE TAL MANERA QUE COMPLETEN SU CARRERA EN CADA UNO DE LOS CILINDROS, EN CADA CARRERA DE DIAFRAGMA ENTRE LOS EXTREMOS DE UN CILINDRO DE UNA SOLA DIRECCION, EN LA MISMA DIRECCION DEL MOVIMIENTO Y EN EL MISMO MOMENTO DE TIEMPO, COMPENSANDO ASI CUALQUIER VARIACION EN LA FUERZA DE ACCIONAMIENTO SOBRE CADA UNO DE LOS DIAFRAGMAS EN SUS CILINDROS.
