Abstract
A breath-actuated dry powder medicament inhalator device having a housing and a conduit mounted within the housing defining an air passageway therethrough having an aperture in the sidewall thereof. A blister-type strip of sealed containers arranged in a matrix of rows and columns wherein the columns extend generally diagonally to the longitudinal axis of the strip is secured in a two-piece cage adapted for being rotatably mounted around the conduit of the inhalator device. Advancement means are provided for rotatably moving the two-piece cage and blister strip contained thereby in a generally helical pathway relative to the conduit so as to successively advance each of the sealed containers of the blister strip into registration with the conduit aperture. Piercing means are associated with the housing for successively piercing each of the sealed containers of the blister strip when advanced into registration with the conduit aperture by the advancement means in order to introduce the dry powder compound contained therein into the air passageway of the conduit.
