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.

Oxygen concentrator, control method, and control program

An oxygen concentrator is provided with a controller for recovering an oxygen concentration to a level suitable for treatment in a short period of time by selecting an optimum purge time corresponding to the deterioration state of an adsorbent. The judgment of moisture-absorption deterioration is performed when the detected value of the oxygen concentration sensor is equal to or less than a control value of the oxygen concentration in the oxygen-enriched gas and the detected value of the pressure sensor is equal to or more than an adsorption pressure at which the oxygen concentration increases significantly before and after the control to reduce the purge time, and control of reducing a time for the purge step shorter than a preset time is performed.

Oxygen concentrator

The present invention provides an oxygen concentrator which allows the flow rate setting to be changed safely and securely by the patient using a remote control device, the oxygen concentrator comprising a control means which does not allow the operation of the flow rate setting change button unless the remote control device receives the information on the flow rate setting value of the oxygen-enriched gas supplied by the current oxygen concentrator main body.
