摘要： A delivery device for use in administering a dry powder to a biological subject's airway is provided. The device comprises (a) a housing having an inlet in fluid communication with an outlet for delivering a flow of gas to the subject's airway; and (b) one or more cantilever structures located within the housing. Vibration of the one or more cantilever structures facilitates entry of the dry powder into the flow of gas, such that the dry powder can be delivered by the flow of gas through the outlet to the subject's airway. Also provided is a container for releasably storing a particulate composition, the container comprising a shell sealed by a seal in which the particulate composition is stored, wherein a puncturing device for rupturing the seal to release the particulate composition is housed within the shell. Further provided are associated methods for administering dry powder using the delivery device and/or container.
