Abstract
An inhalation device having an elongate housing having a passageway for the movement of air therethrough. The passageway terminates in an emptying chamber adjacent that end of the housing which is adapted for insertion into the mouth or nasal passages of a user thereof. The housing has means for receiving and opening a container holding a unit dose of powdered medicament for administration. The opening means includes first means for placing the interior of the opened capsule in communication with the atomosphere and second means for placing the interior of the opened capsule in communication with the emptying chamber via the passageway in the housing. During inhalation, air drawn through the first means causes the powdered medicament to be expelled from the container through the second means, the passageway and the emptying chamber into the nose, throat or lungs of the user where beneficial or therapeutic action of the medicament occurs.
