Recent development regarding mixture of H (concentration of 66%) with O (concentration of ~34%) for medical purpose, such as treatment of coronavirus disease-19 (COVID-19) patients, is introduced. Furthermore, the design principles of a hydrogen inhaler which generates mixture of hydrogen (66%) with oxygen (~34%) for medical purpose are proposed. With the installation of the liquid blocking module and flame arresters, the air pathway of the hydrogen inhaler is divided by multiple isolation zones to prevent any unexpected explosion propagating from one zone to the other. An integrated filtering/cycling module is utilized to purify the impurity, and cool down the temperature of the electrolytic module to reduce the risk of the explosion. Moreover, a nebulizer is provided to selectively atomize the water into vapor which is then mixed with the filtered hydrogen-oxygen mix gas, such that the static electricity of a substance hardly occurs to reduce the risk of the explosion. Furthermore, hydrogen concentration detector is installed to reduce the risk of hydrogen leakage. Result shows that the hydrogen inhaler implementing the aforesaid design rules could effectively inhibit the explosion, even ignition at the outset of the hydrogen inhaler which outputs hydrogen-oxygen gas (approximately 66% hydrogen: 34% oxygen).
介绍了医疗用 H（浓度约为 66%）与 O（浓度约为 34%）混合物的最新发展情况，例如用于治疗新型冠状病毒病（COVID-19）患者。此外，还提出了用于医疗目的产生氢气（约 66%）与氧气（约 34%）混合物的氢气吸入器的设计原则。通过安装液体阻挡模块和防火器，氢气吸入器的空气通道被多个隔离区隔开，以防止任何意外的爆炸从一个区域传播到另一个区域。利用集成的过滤/循环模块来净化杂质，并降低电解模块的温度，以降低爆炸的风险。此外，还提供了一个雾化器，将水选择性地雾化成蒸气，然后与过滤后的氢气-氧气混合气混合，从而减少物质的静电产生，降低爆炸的风险。此外，还安装了氢气浓度探测器，以降低氢气泄漏的风险。结果表明，实施上述设计规则的氢气吸入器可以有效地抑制爆炸，即使在氢气吸入器最初输出氢气-氧气气体（约 66%氢气：34%氧气）时也能抑制爆炸。
