Objective To design a portable oxygen concentrator based on solar energy charging.Methods The portable oxygen concentrator was designed by adopting pressure swing adsorption process and the principle of solar panels generating electricity, and using flexible solar panels which converted solar energy into electricity and stored electricity in energy storage power. Results The portable solar oxygen concentrator consisted of the main oxygen concentrator, the solar panel, the energy storage cell and the box. The oxygen flow rate was between 1 L/min and 3 L/min and the oxygen concentration was between 50% and 90%. The power capacity of energy storage cell was 40 Ah and its charge time was about 7 h. The output voltage of so!ar panels was DC12 V. Conclusion Solar energy charging can realize the normal use of the oxygen concentrator when there is no exterior power supply, provide a reliable power support for emergency use, extend the service life, and make the oxygen generator generate breathing oxygen anytime and anywhere.
