Abstract:
1. A nebulizer comprising: a body comprising a reservoir for holding medication; a nozzle for emitting a jet of pressurized gas; a fluid conduit in communication with the reservoir for delivery of the medication proximate the jet to produce an aerosol of medication; a nebulizer outlet in communication with the body for delivery of the aerosol to a patient; an entrainment passage for providing entrainment flow from atmosphere during inhalation by the patient; and 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, the control conduit comprising a gas passage proximate the entrainment passage to allow the control gas to flow across the entrainment passage, wherein, during the inhalation by the patient, the entrainment flow through the entrainment passage substantially prevents the control gas from flowing across the entrainment passage so as to interrupt the delivery of the control gas to the fluid conduit.
