The capsule is broken and the drug powder inside is released into the capsule housing. In this state, when the patient inhales from the inhalation port, air is sucked into the inhalation passage through the inhalation hole, and the airflow is generated in the inhalation passage while the reduced diameter portion accelerates the flow velocity to inhale into the medicine powder inhalation passage. Generate force. This allows
The drug powder discharged into the capsule container is sucked into the suction passage from the drug powder suction passage together with the air flowing into the capsule container from the vent hole. Further, at this time, the air blower is pressed to eject the auxiliary air flow toward the throttle passage of the suction passage, further increasing the flow velocity of the air flow flowing through the throttle passage, and enhancing the suction force of the drug powder suction passage. As a result, the drug powder released into the capsule container can be positively sucked from the drug powder suction passage into the suction passage, and can be sucked into the lungs together with the inhaled air flow, further reducing the burden on the patient. it can. Further, since the drug powder is sucked out by the suction force generated in the drug powder suction passage by the venturi action of the suction passage, the drug powder can be sucked efficiently by one suction operation.
