Abstract
The invention provides a device for dispensing medication in the respiratory system, with provision for breath-activation; open and closed-mouth technique; recording and control of dosage; and enhanced atomization of liquid medication. This is accomplished with a device that uses a medication canister with an integral battery and circuitry, the battery providing power for electro-mechanical activation, counting medication dosage used or remaining, and controlling device activation. The invention has capability for use with dry and wet medication, and is easily cocked with a simple manual action.
