International Classification:

A61M 11/00

US Classification:

12820021, 12820018, 12820014

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.

Abstract:

An atomizing nebulizer for dispensing a substance or medicament is described. The nebulizer is formed with a reservoir base releasably secured to an effluent vent cap that together capture a diffuser and integral dispersing baffle that are further formed with an uptake lumen or channel terminating with a nozzle jet. The diffuser dispersing baffle is positioned relative to the jet nozzle to optimize atomization of any of a number of such substances so as to maximize disbursement of the substance. The reservoir base also incorporates a pressurized fluid-accelerating inlet tube terminated with a metering orifice that cooperates with the nozzle jet when the inlet tube is received within the diffuser uptake lumen or channel. When so received, the nozzle jet axially registers proximate and superior to the orifice to establish a vacuum space that is in fluid communication with a capillary interstice established between the walls of the exterior of the inlet tube and the confronting interior surface of the diffuser lumen or channel. When a pressurized fluid is communicated through the lumen, the orifice, and into the vacuum space towards the nozzle jet, a vacuum develops in the vacuum space that, in combination with the capillary action of the interstice, draws the fluid proximate to the orifice and disperses it into droplets that are then entrained into a fluid stream to be further atomized upon impact with the baffle and then dispensed.
