Abstract

Un dispositivo y metodo para desaglomerar aglomerados de polvo para inhalacion. El dispositivo incluye una entrada (20) conectada a la camara (40) una fuente de polvo para suministrar a la camara con aglomerados de polvo y un flujo de gas que define un torbellino de flujo de fluido dentro de la camara. El dispositivo incluye tambien una salida 22 conectada a la camara para inhalacion de tal manera que el torbellino de flujo de fluido en la camara puede salir desde la camara como un flujo de fluido longitudinal que se dirige a lo largo de un eje (X) longitudinal de la salida, y un flujo de fluido secundario que se dirige afuera desde el eje longitudinal de la salida. Una malla (28) en la salida evita aglomerados de polvo sobre un tamano predeterminado al atravesar la malla, y reduce el flujo de fluido secundario relativo al flujo de fluido longitudinal que sale desde la camara, por lo que se reduce la deposicion de polvo en una boca y garganta de un usuario.
