Multi-dose dry powder inhalation device
First Claim
1. A portable device for the inhalation of a predetermined amount of dry powder compound from a blister-type strip of sealed containers, comprising:
- (a) a housing;
(b) a conduit mounted within said housing defining an air passageway therethrough and having an air inlet end and an air exit end and an aperture extending through a side wall of said conduit therebetween, said air exit end being adapted for insertion into the mouth of a user;
(c) a blister-type strip of sealed containers wherein said sealed containers are arranged in a matrix of rows and columns and said columns extend generally diagonally to the longitudinal axis of said strip;
(d) cage means for rotatably mounting said blister-type strip of sealed containers of dry powder compound in a cylindrical configuration around said conduit wherein said rows of said blister-type strip extend generally parallel to the longitudinal axis of said conduit;
(e) advancement means associated with said housing for rotatably moving said cage means in a generally helical pathway relative to said conduit so as to successively advance each of said sealed containers of said blister-type strip into registration with the aperture of said conduit; and
(f) piercing means associated with said housing for piercing each of said sealed containers of said blister strip when advanced into registration with the aperture of said conduit so as to introduce said dry powder compound therein into the air passageway of said conduit;
whereby said blister-type strip will be rotatably and axially moved relative to said conduit as said sealed containers thereof are advanced along said helical pathway and successively pierced for administration of a predetermined amount of said dry powder compound from said inhalation device.

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.

14. In a portable device for the inhalation of a predetermined amount of dry powder compound and characterized by a housing;
- an air passageway provided within said housing having an air inlet end, an air exit end adapted for insertion into the mouth of a user, and an aperture through a side wall at a predetermined location along the length thereof; and
piercing means associated with said housing for piercing a sealed container of said dry powder compound when positioned in registration with the aperture of said air passageway so as to introduce said dry powder compound into the air passageway, the improvement comprising;a blister-type strip of sealed containers of dry powder compound arranged in a matrix of rows and columns wherein said columns extend generally parallel to each other and generally diagonally to the longitudinal axis of said strip; cage means for rotatably mounting said blister-type strip of sealed containers in a cylindrical configuration within said housing and around said air passageway wherein said rows of said blister-type strip extend generally parallel to the longitudinal axis of said air passageway; and advancement means associated with said housing for rotatably moving said cage means in a generally helical pathway relative to said air passageway so as to successively advance each of said sealed containers of said blister-type strip into registration with the aperture of said air passageway; whereby said blister-type strip will be rotatably and axially moved relative to said air passageway as said sealed containers thereof are advanced along said helical pathway and successively pierced for administration of a predetermined amount of said dry powder compound from said inhalation device. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22)
