    • Dry powder inhalers with integrated active energy patient assist dispersal systems are configured with control systems which provide adjustable energy output responsive to the user's inspiratory capabilities and/or the flowability of the dry powder drug being administered. The multi-dose dry drug package includes a piezoelectric polymer substrate (such as PVDF) which flexes to deform and provide mechanical oscillation in a selected region of the package corresponding to the dry powder drug dose in the exit flow path and is thus actively dispersed into the exit flow path of the inhaler during the user's inspiratory activity. Control systems employ fuzzy logic models of the flowability of particular drug formulations (also being able to compensate or allow for the particular type of excipient used) and/or adjust for the real-time measured inspiratory efforts of the user. Manufacturing process control systems can adjust certain parameters in response to a fuzzy logic model of the flowability of the dry powder and other conditions associated with the dry powder drug being produced and/or dispensed.
    • 具有集成的活跃能量患者辅助分散系统的干粉吸入器配置有控制系统,其响应于使用者的吸入能力和/或所施用的干粉药物的流动性而提供可调节的能量输出。 多剂量干药包包括压电聚合物基材(例如PVDF),该压电聚合物基体在与出口流动路径中的干粉药物剂量相对应的包装的选定区域中弯曲变形并提供机械振荡,因此主动分散于 用户吸气活动期间吸入器的出口流动路径。 控制系统使用特定药物制剂的流动性的模糊逻辑模型(也能够补偿或允许所使用的特定类型的赋形剂)和/或调节用户实时测量的吸气努力。 制造过程控制系统可以响应于干粉流动性的模糊逻辑模型和与所生产和/或分配的干粉药物相关的其它条件来调节某些参数。
