Abrégé
(EN)
A unit dose dry powder inhaler (20) has a dispersion chamber (108), optionally including one or more beads. A blister is supported adjacent to the dispersion chamber (108). A mouthpiece cover (22) is removable from a mouthpiece (96), with movement of the mouthpiece cover (22) causing the blister (120) to open. An air flow path extends past or under the blister (120) and into the dispersion chamber (108). As a result, the blister (120) remains sealed until the inhaler (20) is ready for use. The blister (120) is then automatically opened when the mouthpiece cover (22) is removed from the mouthpiece (96). Pharmaceutical dry powder (126) is released from the blister (120) and entrained in air flow through the inhaler (20), when the user inhales on the mouthpiece (96). The powder (126) is dispersed in air within the dispersion chamber (108).
