Description

Technical field [0001] The invention relates to the technical field of hydrogen biomedical research, in particular to a hydrogen-oxygen mixed gas preparation device and method. Background technique [0002] Electrolysis of water is one of the main ways to produce hydrogen. Most of the hydrogen products currently on the market are produced by electrolysis of water. The electrolysis of water can produce 66.7% and 33.3% of mixed gas, the ratio of hydrogen to oxygen is 2:1, the concentration of hydrogen produced by the cathode is 66.7%, and the concentration of oxygen produced by the anode is 33.3%. In addition, pure hydrogen and oxygen can also be obtained by separately collecting the gas at the anode and cathode. [0003] In clinic, we need the oxygen concentration in the mixed gas to be roughly the same as the environment, and in scientific research, we need to control the oxygen concentration in the mixed gas to be the same as the environment. Therefore, neither the mixed gas pr...
