An incentive inhaler device includes an inhalation device, at least one incentive toy coupled to the inhalation device, and at least one separator. The inhalation device has a respiration device and a connector that is linkable to a delivery device. The delivery device can deliver drugs, aerosols, powder and gas. The incentive toy is respiration driven and has at least one of a visible characteristic and an audible characteristic. The separator decouples the toy from at least one component of the inhalation device to ensure directional flow of respirational air which drives the toy. The separator can include a valve, a filter, or a baffle.

Inhalation device for producing a drug aerosol

A device for delivering a drug by inhalation is disclosed. The device includes a body defining an interior flow-through chamber having upstream and downstream chamber openings, and a drug supply unit contained within the chamber for producing, upon actuation, a heated drug vapor in a condensation region of the chamber. Gas drawn through the chamber region at a selected gas-flow rate is effective to form drug condensation particles from the drug vapor having a selected MMAD between 0.02 and 0.1 MMAD or between 1 and 3.5 μm. A gas-flow control valve disposed upstream of the unit functions to limit gas-flow rate through the condensation region to the selected gas-flow rate. An actuation switch in the device activates the drug-supply unit, such that the drug-supply unit can be controlled to produce vapor when the gas-flow rate through the chamber is at the selected flow rate.

Thin-film drug delivery article and method of use

An article for use in an aerosol device, for producing an aerosol of a drug composition is disclosed. The article includes a heat-conductive substrate having a surface with a selected surface area, and a drug composition film on the substrate surface having a selected film thickness of between 0.05 and 20 μm. The film thickness is such that an aerosol formed by vaporizing the drug composition by heating the substrate and condensing the vaporized compound contains 10% or less drug-degradation product and at least 50% of the total amount of drug composition contained in the film. The selected substrate surface area is such as to yield an effective human therapeutic dose of the drug aerosol. Also disclosed are methods of making and using the article.

Continuous high-frequency oscillation breathing treatment apparatus

A continuous high-frequency oscillation breathing device delivers therapy during both inhalation and exhalation in order to assist in clearing secretions from the lungs. A fixed shrouded-venturi patient interface circuit is combined with medicated aerosol to deliver continuous high-frequency oscillation therapy. Fixed open apertures in the patient interface circuit allow ingress and egress of flow, and are calibrated to allow exhalation and prevent stacking of successive breaths.

Various embodiments of a breath-activated nebulizer with flow-based 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 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. In some exemplary embodiments, the control conduit may comprise a gas passage proximate the entrainment passage to allow the control gas to flow across the entrainment passage. During the inhalation by the patient, the entrainment flow through the entrainment passage may substantially prevent the control gas from flowing across the entrainment passage so as to interrupt the delivery of the control gas to the fluid conduit.
