<p>PROBLEM TO BE SOLVED: To provide an oxygen enrichment apparatus in which the flow rate of oxygen and the inhalation time can be set by a patient and the setting value can be selected by the patient. SOLUTION: In the oxygen enrichment apparatus constituted so that an adsorption column filled with an adsorption agent for preferentially adsorbing gaseous nitrogen is provided, and air is sent into the adsorption column by a compressor, and then nitrogen in air is adsorbed to produce oxygen-enriched air which is stored in a product tank to supply a predetermined amount of the oxygen-enriched air from the product tank, a flow rate control device 15 for controlling the amount of the oxygen-enriched air according to a control pattern, inputting means 32, 35 for inputting the control pattern of the flow rate control device 15 and the operation time of the apparatus, a control section 16 having a recording means for recording the control patterns and the operation times input by the inputting means 32, 35 to be made correspond to each other, and a switching means 36 for selecting several kinds of control patterns and operation times recorded in the recording means of the control section 16.</p> |
