Abstract

Apparatus for portable gas-assisted dispensing of medication not using a fluorocarbon propellant. The apparatus comprises a pressurized supply of gas containing therapeutic gas or mixture of therapeutic gases, and one or more drugs mixed therein, connected to a pressure regulator, wherein the pressure regulator is connected to a gas release switch which is connected to a breath activator. The breath activator is connected to an aspiration chamber, whereby in use when a patient inhales from the aspiration chamber, the inhalation causes the breath activator to engage with the gas release switch to release the therapeutic gas/drug mixture into the aspiration chamber, wherein the therapeutic gas and drug in the aspiration chamber are simultaneously delivered to a patient during inhalation. Alternatively, medication can be stored in a separate drug reservoir adjacent the pressurized supply of therapeutic gas, which medication is drawn into the aspiration chamber by a venturi assembly. In addition, the breath activator can respond to exhalation to measure and record exhalation flow rate.
