Abstract

QUE COMPRENDE: A) UNA CAJA QUE TIENE UNA ENTRADA PARA UN GAS, UNA SALIDA Y UNA CAMARA ADECUADA PARA CONTENER UN MATERIAL EN PARTICULAS; B) UN FLUIDIZADOR DE PARTICULAS QUE PROVEE UNA CIRCULACION FLUIDIZADA DEL MATERIAL EN PARTICULAS CON EL GAS, EN DICHA CAMARA, AL PONER EN FUNCIONAMIENTO EL DISPOSITIVO; Y, C) UN CLASIFICADOR DE PARTICULAS EN COMUNICACION POR FLUIDO CON LA CIRCULACION FLUIDIZADA ENTRE LA CAMARA Y LA SALIDA. DONDE, (B) CAUSA UNA CIRCULACION DE TORBELLINO DEL MATERIAL EN PARTICULAS FLUIDIZADO GENERANDO: a) UNA REGION CENTRAL DE BAJA PRESION DENTRO DE LA CAMARA EN COMUNICACION POR FLUIDO CON LA ENTRADA, DE MODO QUE EL GAS CIRCULA DENTRO DE LA CAMARA; b) UNA REGION EXTERIOR DE ALTA PRESION DENTRO DE LA CAMARA EN COMUNICACION POR FLUIDO CON LA SALIDA, DE MODO QUE EL GAS CIRCULA DESDE DICHA REGION EXTERIOR HASTA LA SALIDA; Y (C) PERMITE QUE PARTICULAS DENTRO DEL MATERIAL CON UN TAMANO INFERIOR O IGUAL AL TAMANO E INERCIA PREDETERMINADOS SE DESVIEN DE LA CIRCULACION DE TORBELLINO Y SALGAN DE LA CAMARA; Y, ASIMISMO EXCLUYE QUE PARTICULAS DENTRO DEL MATERIAL, CON TAMANO SUPERIOR AL TAMANO E INERCIA PREDETERMINADO, SALGAN DE DICHA CAMARA. SE REFIERE TAMBIEN A UN METODO PARA DISPENSAR UN MATERIAL EN PARTICULAS AEROSOLIZADO PARA INHALACIONWHICH INCLUDES: A) A BOX THAT HAS AN INLET FOR A GAS, AN OUTLET AND AN ADEQUATE CHAMBER TO CONTAIN A PARTICULAR MATERIAL; B) A PARTICLE FLUIDIZER THAT PROVIDES A FLUIDIZED CIRCULATION OF THE PARTICULAR MATERIAL WITH THE GAS, IN SUCH CHAMBER, WHEN THE DEVICE IS OPERATED; AND, C) A CLASSIFIER OF PARTICLES IN FLUID COMMUNICATION WITH THE FLUIDIZED CIRCULATION BETWEEN THE CHAMBER AND THE OUTLET. WHERE, (B) CAUSES A CIRCULATION OF FLUIDIZED PARTICULAR MATERIAL WHIRLLING GENERATING: a) A CENTRAL REGION OF LOW PRESSURE WITHIN THE CHAMBER IN FLUID COMMUNICATION WITH THE INLET, SO THAT THE GAS CIRCULATES INSIDE THE CHAMBER; b) AN OUTDOOR REGION OF HIGH PRESSURE INSIDE THE CHAMBER IN FLUID COMMUNICATION WITH THE OUTLET, SO THAT THE GAS CIRCULATES FROM SAID OUTDOOR REGION TO THE OUTLET; AND (C) ALLOWS PARTICLES WITHIN THE MATERIAL WITH A SIZE LOWER OR EQUAL TO THE DEFAULT SIZE AND INERTIA TO DEVIDE FROM THE CIRCULATION OF WHIRLPOOL AND LEAVE THE CHAMBER; AND, IT ALSO EXCLUDES THAT PARTICLES WITHIN THE MATERIAL, WITH SIZE GREATER THAN THE SIZE AND DEFAULT INERTIA, LEAVING THAT CHAMBER. ALSO REFERS TO A METHOD OF DISPENSING AN AEROSOLIZED PARTICULAR MATERIAL FOR INHALATION
