Abstract
The method described relates to conditional dosing and nebulisation of a liquid or powdered preparation for inhalation. The condition for dosing and nebulisation of the preparation is that the inhaling person must produce an inhalation power according to his or her constitution and which is sufficient for an optimum effect of the inhaled preparation. Without this minimum inhalation power, no dosing and no nebulisation of the preparation is possible. The corresponding inhalation device comprises a known device for dosing and nebulising (without condition) and additional means which inhibit actuation of the device by positive locking until the minimum inhalation power is produced by the inhaling person. A preferred embodiment has, for dosing and nebulisation, a reservoir with a dosing and nebulising pump and, for said positive locking, a ball (13), which is loosely housed in a corresponding ball chamber (14). Upon inhalation, an air stream is generated through the ball chamber (14), which moves the ball (13) out of its locking position, into which it is driven by the force of gravity. so that the positive locking mechanism is released and the pump can be actuated manually.
