Abstract：Objective To design a set of portable oxygen generator system that can remote measurement and control for disaster onsite
emergency medical rescue. Methods The pressure swing adsorption technology was comprehensively optimized to improve
the effective use recovery rate of the air source of the oxygen generator by supplying large flow of clean and dry air source and
developing related core components, so as to achieve the real-time monitoring oxygen concentration, oxygen production flow
and oxygen production pressure indicators; combined with variable self-adjusting oxygen generation design, adapt to the field
environment of broad spectrum adaptability; through the digital control system man-machine interface and general packet wireless
technology, real-time online monitoring and browsing parameters, to build a convenient and stable intelligent operating platform,
develop the remote monitoring terminal real-time interactive equipment operating status information with customers. Results The
simulation results of emergency scenarios showed that the portable oxygen generator could move (95 kg), the output pressure was
stable (0.38-0.45 MPa), and the flow rate was stable (15-20 L/min). The connection of the portable oxygen generator can basically
guarantee the oxygen supply demand of the emergency ventilator. When the output oxygen concentration of the ventilator reached
more than 90%, the portable oxygen generator actually measured the oxygen concentration of 94.4%, oxygen generation flow rate
of 21 L/min, oxygen generation pressure of 0.404 MPa, the physical and chemical indexes of the output oxygen were in line with
GB 8982-2009 Medical and Aviation Respiratory Oxygen Standard. At the same time, during the operation, the touch screen manmachine
interface could display the running state of the portable oxygen generator in real time, and set the running parameters by
itself, so as to realize remote operation and real-time monitoring of the running state. Conclusion The remote measurement and
control portable oxygen generator device has the advantages of fast response, convenient transfer, high oxygen production efficiency
and simple operation. It meets the requirements of portable device and can be used for emergency medical rescue gas supply in
disaster environment.
