METERED DOSE NEBULIZER

摘要

A nebulizer includes a venturi nozzle positioned at the outlet end of an air line and oriented horizontally and located within a patient's oral cavity when in use. A canister port is located at the inlet end of the air line and receives a gas canister. A valve is actuable to allow a metered flow of gas at a predetermined pressure and time to flow from the gas canister through the air line and venturi nozzle. A medication receiver is carried by the nebulizer body proximal to the venturi nozzle. A suction line extends from the venturi nozzle to the medication receiver and draws medication upward from a medication container and mixes it with air passing through the venturi nozzle and nebulizes the medication.
