This paper deals with a simple approach of producing three gases that are oxygen, nitrogen and pressurized air by using a mobile three gas extractor. Indeed, the proposed medical device integrates the following modules driven by an Arduino Mega 2560 board: Module of filtration and production of air made of filters, compressor and a cooling coil; module of oxygen and nitrogen production based on pressure swing adsorption (PSA) method and using the zeolite molecular sieves that restrain nitrogen and produce oxygen. The device is equipped of pressure sensors to control the output pressure of the gases. This implemented equipment has been tested and we obtained promising results. Indeed, a percentage of oxygen of 82 % has been reached. We have produced pressurized air with a pressure of 2.5 bars.
