EINE INHALATIONSVORRICHTUNG |
摘要 |
The present invention relates to an inhalation device for use with an inhaler ( 5 ) comprising a dispersion chamber ( 18 ) for fluid communication with the inhaler ( 5 ) and a suction chamber ( 19 ) in fluid communication with the dispersion chamber ( 18 ). The suction chamber ( 19 ) is constructed to enable the internal volume of the suction chamber ( 19 ) to be increased during use thereby producing a negative pressure in the dispersion chamber ( 18 ). In this way, the substance to be inhaled can be drawn from the inhaler into the dispersion chamber ( 18 ) for subsequent inhalation. |
