AN INHALATION DEVICE

摘要

An inhalation device (10) includes an ejector head (16) having one or more drop generator(s) (18). A reservoir (14), adapted to contain a pharmaceutically active ingredient (12) therein, is in selective fluid communication with the drop generator(s) (18). Electronic circuitry (20) is in electronic communication with, and operatively controls the drop generator(s) (18). Further, the electronic circuitry (20) is responsive to either a predetermined fault condition or an operational condition. The electronic circuitry (20) deactivates the drop generator(s) (18) in response to the predetermined fault condition, and the electronic circuitry (20) activates the drop generator(s) (18) in resonse to the operational condition.
