Abstract
An inhalation device for use with an inhaler is disclosed. The device includes a dispersion chamber constructed for fluid communication with the inhaler and a suction chamber of variable internal volume in fluid communication with the dispersion chamber. The internal volume of the suction chamber can be increased during use, producing a negative pressure in the dispersion chamber, thereby drawing a substance to be inhaled from the inhaler into the dispersion chamber for subsequent inhalation.
