Abstract

SE EFECTUA UNA ALIMENTACION INTERMITENTE DE FLUIDO DE DIALISIS A TRAVES DE UN CATETER DE MICRODIALISIS (A) MEDIANTE UNA BOMBA PORTATIL (B) QUE FUNCIONA CON PILAS EN UNA CANTIDAD CONTROLADA QUE SE CORRESPONDE CON EL VOLUMEN ACTIVO DEL CATETER (A) SIN SOBRANTE Y QUE SE HALLA GENERALMENTE EN EL ORDEN DE ALGUNAS DECIMAS DE MICROLITRO. ESTO PROPORCIONA LA MEJOR CONCENTRACION DE MUESTRA, UNA EXTENSION PROLONGADA DE LA VIDA DE LA PILA Y UNA BOMBA DE PEQUE¥AS DIMENSIONES QUE ES CAPAZ DE SER LLEVADA FIRMEMENTE SOBRE EL CUERPO DE UN PACIENTE.
