Abstract

UN VAPORIZADOR ANESTESICO COMPRENDE UNA ENTRADA (1) PARA GAS PORTADOR Y UNA SALIDA (2) PARA GAS PORTADOR Y AGENTE ANESTESICO, UN PASO (20) SE EXTIENDE ENTRE LOS DOS. UN CANAL (24) SE EXTIENDE ENTRE UNA CAMARA DE VAPORIZACION (8) Y LA SALIDA (2) Y SE PROVEE UN TRANSDUCTOR (5) PARA CONTROLAR DIFERENCIAS DE PRESION ENTRE EL GAS PORTADOR EN EL PASO (20) Y EL AGENTE EN EL CANAL (24) . UNA VALVULA (6) EN EL CANAL (24) CONTROLA EL NIVEL DE FLUJO DEL AGENTE QUE HAY ALLI, EN RESPUESTA A UNA SEÑAL CORRESPONDIENTE A LA DIFERENCIA DE PRESION CONTROLADA POR EL TRANSDUCTOR (5).
