Abstract
A foil-cutting device is disclosed for opening a foil protecting a dose of medical power carried by a dosing cassette or the like for an inhaler device. The dosing cassette will in a typical embodiment carry a number of prepared doses ( ), which for protection of the medical powder are covered by a metallic or plastic foil ( ). The foil-cutter device of the present invention provides a tool ( ) for accessing a selected sealed dose of medical powder of the cassette during an inhalation process using a dry powder inhaler (DPI). When a user inhales through the DPI the foil-cutter opens the foil ( ) for access to a pre-metered powder dose ( ). The foil-cutter arrangement ensures that no access is permitted to the pre-metered dose during any other circumstances. Particularly the present invention is adapted to be applied in an inventive continuous inhaler prolonging the release of a powder dose during the inhalation of the medical powder.
