AIRFLOW ADAPTOR FOR A BREATH-ACTUATED DRY POWDER INHALER |
摘要 |
A deagglomerator for a breath-actuated dry powder inhaler comprising: an airflow adaptor (500); an inner wall (512) defining a swirl chamber (514); a dry powder supply port (522) in the first end (518) of the swirl chamber; at least one inlet port (524,525) in the inner wall of the swirl chamber adjacent to the first end of the swirl chamber providing fluid communication between a region exterior to the deagglomerator and the first end of the swirl chamber; an outlet port providing fluid communication between the second end (520) and the airflow adaptor (501); and wherein the airflow adaptor comprises at least one swirl chamber by-pass port (502,503,504,505) for allowing air to flow from a proximal end of the airflow adaptor to a distal end of the airflow adaptor independently of the swirl-chamber when a breath-induced low pressure is applied to the distal end of the airflow adaptor. |
