Abstract

Se describe un desaglomerador para ser usado como un inhalador de polvo seco activado por la respiración para desintegrar los agregados y micronizar las partículas de polvo seco antes de la inhalación del polvo seco por parte de un paciente que use el inhalador. El desaglomerador incluye una pared interior que define una cámara de torbellino que se extiende a lo largo de un eje desde un primer extremo hasta un segundo extremo, un orificio de suministro de polvo seco, un orificio de entrada y un orificio de salida. El orificio de suministro está en el primer extremo de la cámara de torbellino para brindar una comunicación fluida entre un pasaje de suministro de polvo seco de un inhalador y el primer extremo de la cámara de torbellino. El orificio de entrada está en la pared interior de la cámara de torbellino, ayacente al primer extremo de la cámara de torbellino y brinda una comunicación fluida entre una región exterior del desaglomerador y la cámara de torbellino. El orificio de salida brinda comunicación fluida entre el segundo extremo de la cámara de torbellino y una región exterior del desaglomerador, con lo que una presión baja inducida por la respiración en el orificio de salida genera flujos de aire dentro de la cámara de torbellino a través del orificio de suministro de polvo seco y el orificio de entrada. Los flujos de aire colicionan entre sí y con la pared interior de la cámara de torbellino antes de salir a través del orificio de salida, de forma tal que el polvo seco llevados por los flujos de aire se desintegra y microniza. El desaglomerador también incluye paletas en el primer extremo de la cámara de torbellino para crear colisiones e impactos adicionales del polvo seco llevado por los flujos de aire.
