Oxygen concentrators also known as oxygen generators are widely used in medical, healthcare industry to generate oxygen for patients. Oxygen concentrators were invented in the 1970’s and are used for oxygen generation from atmospheric air in a variety of industries ever since.
We here develop a diy oxygen concentrator to generate oxygen from atmospheric air using pneumatic supply. Our machine makes use of pneumatic pressure along with zeolite vessels a separate pressure vessel along with pressure sensors, oxygen sensors and leakage sensors to develop this system.
We first use atmospheric air through an external compressor to drive air through our system by valves. The valves drive air through zeolite vessels. We here hold the compressed air through the zeolite vessels so the atmospheric N2 goes through a quadruple moment and the oxygen and other gases are lest free to move. Then release the outlet valves of the vessel to drive the oxygen rich air to the second pressure vessel. The separated N2 is then flushed out through other valve. We simultaneously monitor for leakages as high oxygen levels may fuel combustion. On leakage detection we sound a buzzer and auto shutoff the system.
The oxygen rich air in second pressure vessel is then pushed through to patient on a regulated basis or supplied to the ventilator as required. The pressure sensors and valves work in coordination to achieve the desired output. The pressure and oxygen content of generated air is parallel displayed on a screen to keep track. The entire system is run by a microcontroller to ensure smooth operation.
Thus we successfully develop a oxygen concentrator generator to assist patients in COVID pandemic and other emergency situations.
Note: This kit is for educational purposes only and can be used to understand PSA technology by students and researchers. It makes use of Zeolite 13x for best learning output. This kit is not fit for use on patients as it does not guarantee oxygen purity and regular supply.
