Patent ID: 8714149

Claim:
An airflow adaptor for a breath-actuated dry powder inhaler, the airflow adaptor comprising: a first conduit having a proximal end and a distal end, wherein the proximal end allows fluid communication from a deagglomerator outlet port to the distal end of the first conduit, at least one second conduit for allowing air to flow from a proximal end of the adaptor to a distal end of the adaptor independently of the airflow in the first conduit when a breath induced low pressure is applied to the distal end of the airflow adaptor, a first circumferential flange at the distal end of the first conduit, at least one aperture in the first circumferential flange, a second circumferential flange at the proximal end of the airflow adaptor, at least one aperture in the second circumferential flange, and wherein the at least one second conduit comprises a tube connecting the at least one aperture in the first circumferential flange with the at least one aperture in the second circumferential flange.
