Abstract

A device for applying a mixture of air and vapor to the nasal mucous membrane at temperatures not exceeding 47.degree. C. comprising a water reservoir; a steam generating means within the reservoir; gas inlet means for the inlet of the gaseous medium; an outlet conduit for conducting a mixture of gas and steam away from said water reservoir, said outlet means including a first end and a second end, said first end of said outlet conduit including an outlet means for said gas stream mixture; a hollow mixing space between said gas inlet means and said second end of said outlet conduit means; a pressure-equalizing and water drainage opening connecting between said hollow mixing space and said water reservoir; and a steam outlet opening separate from said pressure-equalizing and water drainage opening and communicating with said steam generating means, positioned within said hollow mixing space and having a hydraulic diameter such as to allow outflow of steam under its own vapor pressure, whereby said steam is injected into said hollow mixing space and mixed with said gaseous medium therein and a substantially homogeneous mixture of said steam and said gaseous medium is delivered to said second end of said outlet conduit means.
