  • Publication number: 20130112600
    Abstract: A selective hydrogen adding equipment for living organism applicable fluid, comprising a hydrogen generating system and a hydrogen bubble forming implement, the hydrogen bubble forming implement having a gas/liquid separating section including an open-close type valve, wherein the hydrogen bubble forming implement is disposed in a closed container storing living organism applicable fluid and the hydrogen gas is supplied into the closed container storing living organism applicable fluid via the gas/liquid separating section thereby to provide living organism applicable hydrogen-contained fluid, and wherein the open-close type valve is opened by a gas pressure of hydrogen gas generated in an internal of the hydrogen bubble forming implement owing to a reaction between the hydrogen generating system and the generating-purpose water thereby to exhaust hydrogen gas into the closed container as an external of the hydrogen bubble forming implement while the open-close type valve is closed after the exhaust.

  • Publication number: 20130019757
    Abstract: A selective hydrogen adding equipment is provided by which living organism applicable hydrogen-contained fluid is obtained without changing properties of the living organism applicable fluid. Living organism applicable hydrogen-contained fluid is obtained through storing a hydrogen generating system, which contains a hydrogen generating agent as an essential component, in a hydrogen bubble forming implement which has a gas/liquid separating section including a gas-permeable film or an open-close type valve, causing the hydrogen generating system and a generating-purpose water to react in the hydrogen bubble forming implement, and supplying hydrogen gas generated in the hydrogen bubble forming implement into living organism applicable fluid via the gas/liquid separating section.
