    • Aerosol dispensing devices and methods for using the same for administering aerosolized drugs to a subject are provided. Aspects of the aerosol dispensing device include an aerosol production unit configured to produce an aerosol from a liquid containing a pharmaceutically active drug, and a burst valve adapted to mechanically open in response to a subject's inhalation. The burst valve is configured to prevent airflow through the device until the subject's inhalation produces an operational pressure difference across the burst valve. In some embodiments, the operational pressure difference can be 15 cm H2O or less. Aspects of the invention can also include a heating element configured to evaporate water from aerosol droplets. The devices and methods of the invention find use in a variety of applications, such as in applications in which it is desired to administer an aerosolized drug to a subject.
    • 提供了气雾剂分配装置及其用于向受试者施用雾化药物的方法。 气溶胶分配装置的方面包括气溶胶生成单元,其构造成从含有药物活性药物的液体产生气雾剂,以及适于根据受试者的吸入机械打开的爆裂阀。 爆破阀配置为防止气流通过设备,直到受试者的吸入产生跨爆破阀的操作压力差。 在一些实施例中,操作压力差可以是15cm H 2 O或更小。 本发明的方面还可以包括被配置为从气溶胶液滴蒸发水的加热元件。 本发明的装置和方法可用于各种应用中,例如在期望向受试者施用雾化药物的应用中。
