A dry powder drug administration device comprises a flow passage member (10), a drug powder storage container (19), and a drug administration metering component. An inverted conical drug powder storage container (19) is disposed on an upper portion of a case body. An annular manual rotation portion (3) is disposed outside the upper portion of the case body. A rotational slide passage (23) is disposed on an outer surface of the upper portion of the case body. A sliding block (26) is disposed at an inner side of the annular manual rotation portion (3) correspondingly. A first elastic member (25) is disposed between the annular manual rotation portion (3) and the upper portion of the case body. A gas inlet (12) is disposed at an end of the rotational slide passage (23). The flow passage member (10) is disposed in the case body. A suction nozzle (11) is disposed outside the case body. A suction nozzle cover is disposed outside the suction nozzle (11). A drug administration metering component is disposed below the inverted conical drug powder storage container (19). A raised vibration tooth (21) is disposed at a lower end of the inverted conical drug powder storage container (19). A stirring gear (28) disposed on a transmission sleeve (27) is fit with the raised vibration tooth (21), so as to form a vibration component for enabling an outlet of the inverted conical drug powder storage container (19) to generate vibration. The dry powder drug administration device is applicable to the field of design and manufacturing of dry powder inhalation drug administration devices with various specifications.Linvention concerne un dispositif dadministration de médicament sous forme de poudre sèche qui comprend un élément de passage découlement (10), un contenant de stockage de poudre sèche (19) et un composant de dosage dadministration de médicament.
