DUAL-CANISTER INHALER HAVING A SPACER AND EASY TO OPERATE LEVER MECHANISM

摘要

The present invention relates to a dual-cannister inhaler (figure 1) for effectively delivering medications by inhalation through the mouth of patients, having a spacer (24) for more effectively mixing the medication and air, and easy to operate lever (23) and canister selection mechanisms (21). A preferred embodiment of the invention has universal receptors (10 and 11) for two metered dose inhaler canisters. A lever arm is provided that is opposed to the body of the inhaler, which allows a patient to use the entire hand to activate the metered dose inhaler canister. A simple and easy to operate sliding selector permits one-handed control of the canister selector. In a preferred embodiment a valve assembly (62) and whistle (63) are included in the inhaler to improve the consistency and effectiveness of delivery of medication to the lungs of a patient.
