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.

Abstract: An apparatus to selectively introduce a fluid from one of a plurality of containers into a stream of water flowing through a shower head. The apparatus comprises a housing, a main water passageway therethrough, a plurality of bottles containing fluid to be fed therefrom, supplemental passageways coupling the bottles and the main water passageway whereby fluid from the container may flow to the main passageway by venturi forces created by flowing water, a valve mechanism means movable between open and closed positions by the venturi forces to allow or preclude the feeding of fluid to the flow of water, and user controlled means to selectively allow the valve mechanism to be coupled with the venturi force. Also disclosed is the method for selectively introducing a fluid from a container into a stream of water flowing through a shower head by venturi forces of the flowing water.
