Patent ID: 6866041

Claim:
An apparatus for concentrating the oxygen content of and injecting aroma into a stream of air and adapted to deliver a stream of air to nostrils of a person, comprising: an air compressor and a compressor motor drivably connected to said air compressor for drawing a stream of air out of the atmosphere surrounding the apparatus; first and second sieve beds in fluid communication with said air compressor, each said sieve bed containing a quantity of nitrogen absorption material; sieve input valve means and sieve output valve means in fluid communication with each of said first and second sieve beds and having an air stream nipple; a cycle timer connected to sieve input valve means and to said sieve output valve means; and valve switching means connected to said cycle timer and to said sieve input valve means, alternately delivering the stream of air into said first sieve bed and into said second sieve bed; such that each of said first and second sieve beds extracts nitrogen from the air stream, such that the proportion of oxygen in the air stream exiting said sieve beds is elevated, and as said input valve closes for each said sieve bed, sieve bed output valve means of each said sieve bed opens and vents nitrogen to the atmosphere; an aroma chamber containing aroma releasing material in fluid communication with said first and second sieve beds, such that the stream of air is delivered through said aroma chamber and receives and retains an aroma, said aroma chamber comprising a chamber tube having a tube first end fitted sealingly around said air stream nipple and having a tube second end, and comprising a diffuser adaptor fitted into and secured within said tube second end, said diffuser adaptor comprising a mass of air passing filter material fitted into said chamber tube and impregnated with the aroma releasing material, and comprising a chamber nozzle having a diameter smaller than that of said chamber tube with a radial circular flange secured within said chamber tube, and oriented such that said chamber nozzle protrudes outwardly from said tube second end; and a canula in fluid communication with said aroma chamber with said aroma chamber and comprising an exit port with a nose delivery nozzle.
