The present invention relates to an inhalation device for medicines powdered to be received by a patient as an air stream generated by inhalation, the inhalation device comprising at least one powder reservoir, a powder dosage from the at least one powder reservoir. A metering means for repeatedly metering, a transfer mechanism for moving said metering means from a filling position for accepting a powder dose to an empty position for discharging said powder dose into a powder channel, for manual operation by said patient At least one operating device, wherein the operating device is operatively connected to the transfer mechanism, the at least one dosage of powder being quantified in operation and including a dosing key acting on the transfer mechanism when pressed by the patient; It includes one operating device. Further comprising an advance mechanism for advancing a counter means each time the inhalation device is operated by the patient such that a powder dose is discharged into the powder channel, the counter means further comprising a predetermined number of quantitative cycles after detection of the index And a mechanical index coupled to the dosing key and / or the at least one operating device and / or a locking mechanism that blocks the transfer mechanism. The locking mechanism also comprises a locking lever 7 for positive engagement with the administration key 5 and / or the at least one operating device and / or the transfer mechanism in the blocked condition. The suction device 1 comprises signaling means in which the locking lever 7 engages the mechanical index after the predetermined number of quantitative cycles and is integrally formed with the locking lever.본 발명은 흡입으로 발생된 에어 스트림으로써 환자에 의해 수용되도록 분말화된 의약품들을 위한 흡입 장치에 관한 것이고, 상기 흡인 장치는 적어도 하나의 분말 저장부, 상기 적어도 하나의 분말 저장부로부터 분말 투여량을 반복적으로 정량하기 위한 정량 수단, 분말 투여량을 수용하기 위한 충전 위치로부터 분말 채널 로 상기 분말 투여량을 배출하기 위한 비움 위치로 상기 정량 수단을 이동시키기 위한 이송 메카니즘, 상기 환자에 의한 수동 작동을 위한 적어도 하나의 동작 장치로서, 상기 동작 장치는 상기 이송 메카니즘에 작동 연결되어
