An apparatus for producing an oxygen enriched gas having a compressor for supplying air under pressure, a unit for producing a gas enriched with oxygen from the air supplied from the compressor, a gas storage tank for reserving the oxygen enriched gas produced from the producing unit, a flow rate setting unit to set a flow rate of the oxygen enriched gas delivered from the gas storage tank, and a regulating unit for adjustably regulating an oxygen concentration of the oxygen enriched gas in response to a change in a requirement of an oxygen concentration of the oxygen enriched gas obtained at an outlet of the apparatus.

An apparatus for producing an oxygen enriched gas from air comprising: an air source means comprising a compressor for supplying air under pressure to be enriched with oxygen; a means for producing a gas enriched with oxygen from said air supplied from said air source comprising at least one bed of adsorbent capable of adsorbing nitrogen more readily than oxygen; a first gas conduit means for fluid connection between said air source means and an inlet for said means for producing a gas enriched with oxygen through which air is introduced and an outlet thereof through which said oxygen enriched gas is discharged; a gas storage means for reserving a given amount of said oxygen enriched gas produced by said means for producing a gas enriched with oxygen; a second gas conduit means for fluid connection between said outlet of said means for producing a gas enriched with oxygen and said gas storage means; a third gas conduit for delivering said oxygen enriched gas from said gas storage means toward an outlet of said apparatus; a flow rate setting means for setting a flow rate of said oxygen enriched gas delivered from said gas storage means to said outlet of said apparatus via said third gas conduit means, said flow rate setting means being arranged in said third conduit means; a concentration regulating means for adjustably regulating an oxygen concentration of said oxygen enriched gas delivered from said outlet to said apparatus in response to a change in a requirement for an oxygen concentration in said oxygen enriched gas, and said apparatus further comprising a fourth gas conduit means for providing a fluid communication between said compressor and said gas storage means; a flow control means arranged in said fourth gas conduit means for adjustably regulating said fluid communication between said compressor and said gas storage means, thereby controlling a flow rate of said air from said compressor to said gas storage means in response to a change in a requirement for an oxygen concentration of said oxygen enriched gas.
