Abstract
A dose selective breath actuated inhaler including a meterless canister storing a pressurized medicament, and a vacuum actuated release, where application of a vacuum to the inhaler initiates a release of the medicament in the canister. The inhaler includes a mechanism for dialing a proper dose of pressurized medicament, a computer for generating a plurality of signals including a solenoid trigger signal, and a solenoid which upon receipt of a solenoid trigger signal actuates a solenoid arm to end the release of the medicament from the canister.

18. A method of administering a substance by inhalation comprising the steps of:
-
providing an inhaler including a meterless canister storing a pressurized medicament, a vacuum actuated release, a computer for generating a plurality of signals including a solenoid trigger signal, and a solenoid having a solenoid arm; applying a vacuum to a mouthpiece portion of the inhaler to trigger release of the medicament in the canister; running a clock function from the time release of the medicament begins; generating the solenoid signal at the completion of the clock function, said solenoid signal actuating the solenoid arm to cease release of the medicament from the canister. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25)
