Abstract
The invention relates to a metering device for fine grained powder (1), in particular for medicinal powder (1) for pulmonary administration, and to a method for operating the metering device. The metering device comprises a powder pump and a metering mechanism (3), wherein the metering mechanism (3) comprises a continuous powder passage (4) and at least one metering chamber (5) with an outlet valve (6). The metering chamber (5) branches off from the powder passage (4) at an angle. The metering chamber (5) has a larger cross section than the powder passage (4). The powder (1) is conveyed through the powder passage (4) by means of the powder pump, the at least one metering chamber (5) being filled with the powder (1) in a self-levelling manner. The conveying by means of the powder pump is then interrupted, and at least one target container is filled from the metering chamber (5) with the outlet valve (6) being opened and a residual quantity of powder (1) remaining in the metering chamber (5).
