Abstract
Various embodiments of a breath-activated nebulizer with fluidic control and related methods of using such a nebulizer are disclosed. The nebulizer may include a body comprising a reservoir for holding medication, a nozzle for emitting a jet of pressurized gas, and a fluid conduit in communication with the reservoir for delivery of the medication proximate the jet to produce an aerosol of medication. The nebulizer may also include a nebulizer outlet in communication with an interior of the body for delivery of the aerosol to a patient, a control conduit in fluid communication with the fluid conduit for delivery of a control gas to the fluid conduit to prevent the delivery of the medication proximate the jet, and a fluidic amplifier configured to control the delivery of the control gas to the control conduit.
