The gas generating units 2 and 3 may use a known technique as long as the water W is electrolyzed to generate hydrogen H and oxygen O. For example, there is an apparatus disclosed in Japanese Patent Application Laid-Open No. 2014-95115. That is, the gas generation units 2 and 3 include a tank 21 that stores water W to be electrolyzed, a flat plate-like first electrode 22, a flat plate-like second electrode 23, and a separator 25.

  Here, the water W to be electrolyzed is an aqueous solution containing ions other than these in addition to hydrogen ions and hydroxide ions. Examples of the water W include tap water.

  In addition, the voltage required for the electrolysis of water W can be made low, so that electrical conductivity is high. Therefore, the water W may be an acidic aqueous solution, an alkaline aqueous solution, or an aqueous solution in which a salt is dissolved. However, these solutions may require care in handling or may be troublesome to prepare. Therefore, it is convenient if an aqueous liquid that is easy to handle and obtain (for example, tap water or purified water that can be purchased at a pharmacy) can be used as the water W.

In addition, when the conductivity of the water W is too low, a compound (for example, a salt) that generates ions may be dissolved in the water W. There is no limitation on the salt to be added.

Yes. Moreover, since the gas passing through the separation tank 13 contains hydrogen H, even if a gas downstream from the separation tank 13 ignites, there is a possibility that a higher concentration of hydrogen H exists. The separation tank 13 cuts the upstream side and the downstream side so that the flame does not propagate to a certain collecting pipe 11 or the gas generating units 2 and 3.

  The container 35 is preferably transparent or translucent so that the water level of the water W2 can be confirmed.

  The lid 36 is preferably detachable and can be opened so that the water W2 can be poured into the container 35.

Specifically, the check valve 8 is in a flow path between the first merging portion 41 and the second merging portion 42 of the merging pipe 12 and prevents the mixed gas GM from flowing into the pumps 5 and 6 side. It is out. In the unlikely event that the mixed gas GM containing hydrogen H flows into the pumps 5 and 6, the electric circuit including the pumps 5 and 6 may be exposed to the mixed gas GM and the hydrogen H may be ignited by sparks generated by the electric circuit. The stop valve 8 also prevents this.

  The discharge unit 9 is connected to the outlet end of the merge pipe 12 via a joint 39. The discharge unit 9 is, for example, a nasal cannula or a nasal mask for inhaling gas, and a known technique suitable for inhaling the inhalation gas G together with inhalation can be used. The discharge unit 9 does not discharge hydrogen H or oxygen O alone. When the pumps 5 and 6 are turned off, the discharge unit 9 discharges the mixed gas GM, and the pumps 5 and 6 are operated by only one of them. If so, the suction gas G is discharged.
