Dry powder inhalation device |
| abstract |
Taught herein is a disposable breath actuated dry powder drug inhalation device having a powderized drug storage chamber with integral toroidal geometry and air flow pathways for entraining and breaking up powder aggregates prior to delivery to the patient. The toroidal chamber is fluidly connected by one or more air inlets directed in a non-tangent manner toward the powder to loft and set up an irregular-rotational flow pattern. Also, in fluid connection with the toroidal chamber is a centrally or near centrally located air and powder outlet consisting of one or more holes forming a grid in fluid connection with a channel providing a passageway for powder flow to the patient. |
