Abstract
An apparatus for concentrating the oxygen content of and injecting aroma into a stream of air and delivering the stream of air to the nostrils of a person includes an air intake filter in fluid communication with the air compressor for drawing a stream of air out of the surrounding atmosphere; a sieve bed in fluid communication with the air intake means, each sieve bed containing a quantity of nitrogen absorption material and having sieve bed input and output valve mechanism; so that the sieve bed extracts nitrogen from the air stream so that the proportion of oxygen exiting the sieve bed is elevated, and as the input valve mechanism closes, the sieve bed output valve mechanism opens and vents absorbed nitrogen from the sieve bed to the atmosphere; an aroma chamber containing aroma releasing material in fluid communication with the output valve mechanism.
