Abstract:
An inhalator for administering an air-powder mixture, comprising:an inhalator body including an air intake path for introducing an air into the inhalator body, and an air-powder mixture outlet for discharging the air-powder mixture from the inhalator body; a powder receiving chamber adapted to receive a powder, the powder receiving chamber being disposed within the inhalator body and communicated with an outside of the inhalator body through the air intake path; an air-powder mixture path adapted to transmit the air-powder mixture flowing from the powder receiving chamber to the air-powder mixture outlet; an air-powder mixture reservoir adapted to temporarily store the air-powder mixture flowing from the powder receiving chamber, the air-powder mixture reservoir being disposed within the air-powder mixture path; a diluent air passage adapted to introduce a diluent air into the air-powder mixture reservoir, the diluent air passage communicating the air-powder mixture reservoir with the outside of the inhalator body; and a second diluent air passage adapted to introduce a diluent air into the air-powder mixture path downstream of the air-powder mixture reservoir upon the air-powder mixture flowing from the air-powder mixture reservoir, and a regulator variably controlling an opening area of the second diluent air passage.
