    Molecular sieve pressure swing adsorption utilizes the difference in the adsorption capacity of molecular sieve for oxygen and nitrogen and the characteristic that the adsorption capacity changes with the change of adsorption pressure to produce medical oxygen for the purpose of medical treatment and health care. It has the characteristics of cleanliness and easy access. In order to obtain breathing oxygen simply and conveniently, a miniature oxygen generator for yi was designed by using the molecular sieve pressure swing adsorption principle. Methods: Based on the analysis of the work flow of the molecular sieve oxygen production equipment, the detailed gas circuit and circuit design of the equipment were given. After three-stage filtration treatment, the raw material air is pressurized by an oil-free air compressor and cooled by a condenser, and then enters the adsorption tower equipped with molecular sieve through a reversing control valve. Nitrogen, carbon dioxide and water vapor in the air are selectively adsorbed by the adsorbent. Oxygen passes through the adsorption tower and enters the oxygen storage tank, and is output as product gas after concentration, flow and pressure detection. The single-chip microcomputer is used to control the reversing switching of the reversing valve regularly, and the process of pressurized adsorption, pressure equalization and desorption is realized. The functions of signal detection, human-machine information interaction, fault diagnosis and alarm system during the operation of the equipment are also designed. Results: The oxygen concentration of the product was above 90%, and the concentration could reach 96% at low flow output. The noise of the whole machine is below 55dB, and it has functions such as timing, alarm, blood oxygen and pulse rate detection, and atomized drug delivery. Conclusion: With reasonable selection of equipment components, control devices and innovative structural design, the oxygen generator has stable oxygen concentration and pressure, low noise, high cost performance, and safe and reliable operation.
