Abstract:
1. An oxygen concentrator which allows the flow rate setting value of the oxygen-enriched gas to be changed by remote control operation, comprising an oxygen concentrator main body provided with a flow rate setting means to separate oxygen in air and supply the oxygen-enriched gas generated at a predetermined flow rate and a remote control device to control the oxygen concentrator main body from a distance, the oxygen concentrator main body comprising a communication means to transmit and receive the information on the flow rate setting value to and from the remote control device and a control means A to confirm the information and control the flow rate setting, the remote control device comprising a confirmation button to confirm the flow rate setting value of the oxygen-enriched gas currently supplied by the oxygen concentrator main body, a flow rate setting change button to change the flow rate setting value of the oxygen-enriched gas supplied by the oxygen concentrator main body, a display to indicate the flow rate setting value, and a communication means to transmit and receive the information on the flow rate setting value to and from the oxygen concentrator main body, and the remote control device further comprising a control means B 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.
