ABSTRACT:
The present invention relates to a device for specific inhalation challenges, especially bronchical provocation tests, including a compressed air supply, a particle generator an exposure room, an orofacial mask, a gas-aerosol photometer, a manometer, a valve and a suction pump. The invention also relates to a method of using the device and to an improved particle generator.
