Abstract

The present invention provides for an enhanced eductor element that significantly increases the amount of pressure generated at the siphon tube without significantly increasing the flow resistance through the eductor. The invention further provides for breath- actuated inhalation devices comprising the enhanced eductor element as an actuation mechanism.
