Patent

CA 2228182

A breath-powered inhalation device is disclosed comprising a hollow cylindrical body having an air inlet at one end and an air outlet at another end. The air outlet is narrowed so that air velocity increases as air moves through the outlet. At the air outlet is positioned a releasing mechanism which preferably comprises a fibre tip impregnated with a medicament or the like. As the air rushes past the releasing mechanism, the medicament or the like is atomized and carried into the respiratory tract of the user by the air. The breath-powered inhalation device of the present invention provides advantages over conventional inhalation devices using compressed gases as propellants since it is more compact, simpler and does not require synchronization of activation of the device and inhalation by the user.
