INHALATION APPARATUS FOR POWDER MEDICATIONS

摘要

The inhalation apparatus for powder medications comprises a housing (1) with a rotational dosing ball (15) that is assigned to the orifice of the powder reservoir (12) located in the housing, that is manually actuated and that has a peripheral dosing cavity (17) to accommodate a dose of powder. The dosing ball is connected to a torsion spring (16) and also has a stop piece (20). In addition, a pivotal release flap (14) with a movable stop (14a) is assigned to said dosing ball. The dosing ball is prestressed by turning it until the slot of its stop piece reaches the movable stop of the release flap and is subsequently released by a rotation of the release flap caused by breathing. The medication is released from the dosing cavity as a result of the abrupt deceleration of the dosing ball due to the halting of the stop piece on the bottom of the housing and extensively distributed in the respiratory airflow. The medication can thus be fully inhaled in synchronization with breathing. Overdose or multidose is excluded.
