Abstract

Un inhalador de polvo seco incluye un elemento de almacenamiento de polvo configurado para contener un medicamento en polvo y un canal de entrada recibe el medicamento en polvo desde el elemento de almacenamiento de polvo que es arrastrado en un flujo de aire. El canal de entrada tiene un primer diámetro y define una abertura. El inhalador incluye una cámara de dispersión que recibe el flujo de aire y el medicamento en polvo desde la abertura. La cámara de dispersión tiene un segundo diámetro. El inhalador incluye un accionador alojado dentro de la cámara de dispersión. El accionador oscila dentro de la cámara de dispersión cuando se expone al flujo de aire para desagregar el medicamento en polvo arrastrado por el flujo de aire que pasa a través de la cámara de dispersión. Una relación entre el primer diámetro y el segundo diámetro está entre aproximadamente 0.40 y 0.60 tal que se produce un sonido audible a medida que oscila el accionador. El inhalador incluye un canal de salida a través del cual el flujo de aire y el medicamento en polvo salen del inhalador.
