Abstract: Dry powder inhalers (FIG. 1) 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. 2) 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. 12) employs fuzzy logic to relate in response to a user's inspiratory effort.

Abstract: Methods, systems, and computer program products flowably process dry powders using a non-linear vibratory signal individualized or customized to a target dry powder undergoing processing to facilitate fluidic flow through a flow channel.

Abstract: Methods, systems, and computer program products flowably dispense meted amounts of dry powders using a flexing piezoelectric layer to transmit a vibratory signal to the dry powder to facilitate fluidic flow through a flow channel. The apparatus for dispensing dry powders can include: (a) an elongate flow channel having a width, length, and depth, the flow channel having axially spaced apart inlet and outlet ports, wherein the elongate flow channel is configured to extend in an angular orientation of between about 10-75 degrees relative to the axial direction of flow; (b) a flexible piezoelectric layer configured to overlie the flow channel so that, in operation, the piezoelectric layer is able to flex upwardly away from the lowermost portion of the underlying flow channel; and (c) a signal generator operatively associated with the piezoelectric layer, wherein, in operation, the signal generator is configured to output a signal for flexing the piezoelectric layer in the elongate flow channel.

Abstract: The present invention includes dry powder inhalers and associated multi-dose dry powder packages for holding inhalant formulated dry powder substances and associated fabrication and dispensing methods. The multi-dose package can include a platform body comprising at least one thin piezoelectric polymer material layer defining at least a portion of a plurality of spatially separated discrete elongate dry powder channels having an associated length, width and height; and a metallic material attached to selected portions of the piezoelectric polymer material including each of the regions corresponding to the elongate dry powder channels to, in operation, define active energy releasing vibratory channels. In operation, the elongate channels can be selectively individually activated to vibrate upon exposure to an electrical input.
