Dry powder inhaler |
| abstract |
The dry powder inhaler (20) has a dispersion chamber (30) containing a bead (40). A dose of dry powder (142) is discharged into the chamber or into an inlet (26) tangentially connected to the chamber. As the patient inhales with the nosepiece or mouthpiece (22), air circulates through the dispersion chamber and moves the beads. The bead rotates, bounces, and repeatedly collides with drug particles on the surface of the chamber or on the bead. As the small active drug particles separate from the large carrier particles and separate from each other, a powder spray is produced and inhaled by the patient. The bead is preferably lightweight so that it can rapidly accelerate and move with a slight inspiration. The flow resistance of the inhaler is also reduced by the bead, allowing for greater airflow and powder dispersion without any additional patient effort. |
