Further, the flow of the chemical powder mixed into the air in the capsule K flows through the lower outflow hole H2 formed below the capsule K, the pin insertion hole 12B of the outflow side ventilation passage 12, and the outflow passage 12A. Then, it flows out to the suction passage 5 side. At this time,
Even if there is a powder having a large particle diameter or a powder having a large specific gravity among the powders in the capsule K, the powder can be effectively discharged from the capsule K without being against gravity.

As described above, the drug powder flowing out of the capsule K is diffused into the air as described above, and
Through the patient's mouth and into the lungs through the trachea.

Thus, according to the present embodiment, when the dispenser is used, the inflow-side ventilation path 11 through which air flows into the capsule K is positioned above the capsule storage chamber 10, and the pin insertion hole 11B is inserted into the capsule storage chamber. 10, the outlet side ventilation path 12 is located below the capsule storage chamber 10, and the pin insertion hole 12B is formed in the capsule storage chamber 10
The hole formed in the capsule K by the drilling tool 15 is an upper inflow hole H1 and a lower outflow hole H2. Then, the medicinal powder in the capsule K is stirred by the air flowing into the capsule K from the pin insertion hole 11B, mixed with the airflow flowing out from the lower outflow hole H2 of the capsule K, and is introduced into the lungs of the patient. It can be reached reliably.

In particular, in this embodiment, even if there is a powder having a large particle diameter or a powder having a large specific gravity among the powders in the capsule K, the lower outflow hole H2 formed under the capsule K is formed.
Thereby, the medicine powder can be effectively discharged from the capsule K without opposing the gravity, and the medicine powder remaining in the capsule K can be reduced.

Accordingly, it is possible to prevent a variation in the inhalation amount of the medicinal powder at the time of administration and to administer the medicinal powder to the patient without leaving the medicinal powder in the capsule K, and to administer the prescribed amount of the medicinal powder to the patient. Thereby, the efficacy of the medicinal powder can be enhanced.
