Dry powder inhaler for use with piezoelectric polymer-driven delivery means, and associated blister package comprising a piezoelectric polymer material

The invention includes dry powder and inhaler for holding and water of dried noodles and related multi-dosage dry ring. Multi-dosage dry ring (100) comprises at least one thin washer polymer material (28), wherein the thin washer polymer material (28) is provided with multiple limit with the persistence length, width and height hollow and separating long and thin dry groove (101) at least one part; And which is attached to the washer polymer material (28) while part metallicity material (100m), which is convenient and each area of the long and thin dry groove (101) of the operation according limit the active energy liberation vibration the groove. The operation, the long and long groove suitable for is made of selectively the start wherein the receiver an electric vibration. Dry powder inhaler (10) comprises: The long and thin main body (10b), wherein the first and second main external surface (11, 12) first and second main external surface of the cavity (10c), the dry inhaler (10) further - comprising for shape body ring of the cavity (10c) multi-dosage seal (100). Dry inhaler (10) further - comprising A Bujian (15), wherein A Bujian (15) is adhered is attached of the pivot shaft change of scene of the long and thin main body (10b).
