DISPOSABLE INHALER

摘要

The disposable breath-actuated inhaler comprises a tubular housing which consists of at least two parts (1, 2) terminating the air flow path. The path is open at both ends. The first end forms an air inlet (4) and the second one an air outlet (5). The said housing comprises a compartment for storing a pharmaceutical powder to be inhaled. The compartment (3) for storing the pharmaceutical powder is located close to the air inlet (4) and is covered by a thin foil (6) sealing the compartment in an airtight way. The foil (6) can be removed from the compartment from the outside of the housing. The said housing is shaped with a constriction (9) adjacent to the powder compartment (3) so a turbulent air stream will be obtained at the constriction upon inhalation which will lift the powder out from the compartment (3) and mix the powder with the air stream.
