Abstract:
1. A device for storing and delivering a medicine into an air path comprising: a first chamber that includes an air inlet and an air outlet and defines at least a first portion of an air path from the air inlet to the air outlet for delivery of medicament-entrained air to a user; and a second chamber that includes an outlet opening and is configured to retain medicament in the second chamber in an area that is sealed from the first portion of the air path of the first chamber; wherein the second chamber and the medicament are slidably movable relative to the first chamber from a closed position in which the outlet opening is closed to an open position in which the outlet opening is open to permit air flow into the second chamber and to open fluid communication between the first portion of the air path and the outlet opening of the second chamber, the second chamber being arranged in the open position to prevent clumps of medicament from exiting the second chamber to the air path of the first chamber and such that medicament-entrained air exiting the second chamber from the outlet opening enters the first portion of the air path at a restriction of the air path, and wherein the second chamber is constructed such that the outlet opening of the second chamber contacts the first chamber to close the outlet opening and seal the area from other portions of the first chamber to prevent release of said medicament into the air path when said second chamber is in the closed position.
