DRY POWDER INHALER FOR USE WITH PIEZOELECTRIC POLYMER-DRIVEN DELIVERY MEANS, AND ASSOCIATED BLISTER PACKAGE COMPRISING A PIEZOELECTRIC POLYMER MATERIAL

摘要

THE PRESENT INVENTION INCLUDES DRY POWDER INHALERS AND ASSOCIATED MULTI-DOSE DRY POWDER PACKAGES FOR HOLDING INHALANT FORMULATED DRY POWDER SUBSTANCES. THE MULTI-DOSE PACKAGE (100) COMPRISES AT LEAST ONE THIN PIEZOELECTRIC POLYMER MATERIAL LAYER (28) DEFINING AT LEAST A PORTION OF A PLURALITY OF SPATIALLY SEPARATED DISCRETE ELONGATE DRY POWDER CHANNELS (101) HAVING AN ASSOCIATED LENGTH, WIDTH AND HEIGHT; AND A METALLIC MATERIAL (100M) ATTACHED TO SELECTED PORTIONS OF THE PIEZOELECTRIC POLYMER MATERIAL (28) INCLUDING EACH OF THE REGIONS CORRESPONDING TO THE ELONGATE DRY POWDER CHANNELS (101) 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. THE DRY POWDER INHALER (10) INCLUDES AN ELONGATE BODY (10B) HAVING OPPOSING FIRST AND SECOND OUTER PRIMARY SURFACES (11, 12) WITH A CAVITY (10C) THEREBETWEEN AND A MULTI-DOSE SEALED BLISTER PACKAGE (100) LOCATED IN THE SAID CAVITY (10C). THE INHALER (10) ALSO INCLUDES A COVER MEMBER (15) THAT IS PIVOTABLY ATTACHED TO THE ELONGATE BODY (10B).
