1. Different concentrations of medical oxygen will be configured byadjusting the proportion of oxygen and air.
2. Adjust the oxygen concentration and flow respectively.
3. The surface is processing with anodic oxidation.
4. Equipped with a precise balance device, it outputs stable oxygenconcentration.
5. With an inside alarm system of differential pressure, the safetyvalve will start automatically and produce mixed gas continuouslyto ensure safety of patient. 6. adjust the oxygen concentration from 21% to 100% optionally.
