Abstract
Provided is an oxygen concentration device, a control method, and a control program with which a start-up interval until a desired high-concentration oxygen gas can be supplied can be reduced. The oxygen concentration device includes a pressurized air supply unit for supplying pressurized air, an adsorption tube which concentrates oxygen in the pressurized air by adsorbing nitrogen in the supplied pressurized air to generate oxygen gas, an oxygen gas tank for storing oxygen gas, a flow rate adjustment unit which adjusts an oxygen gas flow rate to be output to the exterior from the oxygen gas tank, and a control unit which controls the flow rate adjustment unit so that the oxygen gas flow rate becomes a set flow rate and controls the pressurized air supply unit so that the pressurized air achieves a supply amount corresponding to the set flow rate.
