Patent ID: 8555874

Claim:
An aerosol transfer device comprising a shaped aerosol accumulation chamber having a central vertical axis, an upper end and a lower end, the chamber having a major dimension, the upper end comprising a nebulizer port and a patient interface port, the lower end comprising an air inlet port, wherein the air inlet port is oriented to be non-aligned with said central vertical axis, said air inlet port further comprising a valve, an outer shell, substantially surrounding the at least said lower end of the aerosol accumulation chamber, the outer shell having one or more air inlet passages about a periphery thereof wherein said one or more air inlet passages is above said air inlet port, said patient interface port fluidically coupled to a patient interface device, and an aerosolized exhaust port intermediate to said patient interface device and to said patient interface port, and wherein a medicament adapted to be nebulized into said nebulizer port generating an aerosol plume, and the accumulation chamber is configured and dimensioned such that upon an inhalation by a patient, ambient air is drawn into the device via the air inlet passage, thence into the body where it flows counter-currently to said aerosol plume thereby efficiently delivering aerosol to the patient.
