Patent number: 9522250Abstract: The objective of the present invention is to allow a hydrogen gas which has a gas mixture concentration of over 4% to be breathed in safely, and to reduce the amount of use of hydrogen gas, which is dangerous, and increase utilization efficiency of the hydrogen gas. The objective of the present invention is also to impart an auxiliary role to a device in the treatment of patients suffering from viral or bacterial pneumonia using hydrogen gas. A hydrogen gas mixture breathing device and a related system employ an intrinsically safe structure and a safety system which prevent occurrence of explosions. A detonation flame arrester, etc. are installed where necessary to provide against electrostatic explosions, etc., and to protect a user's lung function from explosion flames. In addition, a device for supplying aerosol in which a hydroxyl radical is dissolved is also installed, and operating time and volume are appropriately adjusted under the supervision of a professional.Type: GrantFiled: August 19, 2014Date of Patent: December 20, 2016Inventor: Takao Kawamura
