摘要：
In one aspect, embodiments of the present invention provide an aerosolization device for ensuring proper delivery of an aerosolized medication to a user's respiratory system. The aerosolization device may include a conduit, an aerosol generator, a restrictor disposed within the conduit, and an indicator mechanism. The conduit may include a mouthpiece end by which a user may cause inspiratory flow through the conduit. The aerosol generator may include a vibratable mesh. The restrictor may define a plurality of apertures disposed along an outer periphery of the restrictor configured to provide an increase in pressure differential that varies with an inspiratory flow rate within the conduit and to provide a relatively laminar flow downstream of the restrictor compared to upstream of the restrictor. The indicator mechanism may indicate to a user a state of a parameter of the inspiratory flow relative to a predefined desired range.
