The invention relates to a powder inhaling device comprising a body (10) provided with a distribution opening (15), a plurality of pre-dosed receptacles (21), each one containing a dose of powder to be distributed, and receptacle-opening means (30; 50; 18) for opening a receptacle (21) each time the device is actuated. Said device also comprises a dispersion chamber (70) having an inlet (710) connected to an open receptacle (21) during the inhalation and receiving the flow of air and powder from the open receptacle via a supply channel (60), and an outlet (720) connected to said distribution opening (15) via a distribution channel (80). Said dispersion chamber (70) comprises at least one ball (71) movable along a ball path (75) in the dispersion chamber, said dispersion chamber (70) comprising at least one air inlet (72) that is approximately tangential to said ball path (75), the supply and distribution channels (60) extending in the same essentially perpendicular direction to the ball path (75) and to the at least one tangential air inlet (72). |
