INHALATION DEVICES FOR STORING AND DELIVERING MEDICAMENT

摘要

The present invention relates to devices for storing and delivering medicament. A device (100) according to an embodiment of the present invention comprises an air path (103) and a chamber (101) configured for storing and delivering a medicament. The chamber has a substantially curved interior surface and an opening (111) that provides fluid communication with the air path. The opening includes an inlet admitting air from the air path and an outlet for medicament entrained air to exit into the air path. A section of the curved interior surface is configured to redirect at least a portion of the inlet flow toward the inlet flow of air. So configured, some of the redirected flow of air may exit the chamber through the outlet and into the air path while other portions of the redirected flow of air recirculates about the chamber.
