Patent ID: 6889690

Claim:
A multi-dose dry powder drug package for holding pharmaceutical grade formulations of inhalable dry powder substances, comprising: a platform body comprising a plurality of sealed blisters thereon and at least one thin piezoelectric polymer material portion in communication with at least one of the sealed blisters, wherein the sealed blisters comprise a respective at least one of a plurality of spatially separated discrete elongate dry powder channels having an associated length, width and height, wherein the elongate channels have a first rearward curvilinear portion that terminates into a second forward curvilinear portion, and wherein the second curvilinear portion has a smaller perimeter and is disposed downstream of the first curvilinear portion in the direction of flow; a conductive material attached to the piezoelectric polymer material to define at least one active energy releasing vibratory member, and an input signal generating circuit that is operatively associated with the piezoelectric polymer material, wherein the input generating circuit comprises a processor configured to selectively transmit an amplitude modulated non-linear input signal to the piezoelectric polymer material, and wherein the amplitude modulated non-linear signal comprises a plurality of superimposed frequencies, the frequencies corresponding to a priori flow characteristic frequencies of a dry powder held in a respective blister.
