Abstract
Dry powder inhalers (FIG.) 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 being administered. The multi-dose dry drug package (FIG.) a piezoelectric polymer substrate which flexes to deform and provide mechanical oscillation in a selected region of the package corresponding to the dry powder drug which is dispersed during inhalation by a user. Control system (FIG.) employs fuzzy logic to relate in response to a user's inspiratory effort.
