[0023] As shown in Figures 1 and 6, the hydrogen gas supply pipe 9 and the oxygen gas supply pipe 10 are connected to the hydrogen gas supply port 7 and the oxygen gas supply port 8, respectively, and the gas pressure detection pipe 11 and the gas pressure detection pipe 18 are connected to the gas pressure detection pipe connection port 12 and the gas pressure detection pipe connection port 19.

[0024] The detection means 2 consists of a gas pressure detection unit 4 that detects changes in gas pressure inside the gas pressure detection tube 11 and the gas pressure detection tube 18, and a detection result transmission unit 5 that transmits the detection result detected by the gas pressure detection unit 4 to the supply shut-off means 3.

[0027] The pressure sensor 13 is configured to detect slight negative pressure conditions during inhalation (e.g., -30 Pa to -80 Pa) and slight positive pressure conditions during exhalation (e.g., +30 Pa to +80 Pa).

[0028] As shown in Figures 1 and 6, the supply shutoff means 3 is installed in the middle of the hydrogen gas supply pipe 9 and the oxygen gas supply pipe 10, and includes a solenoid valve 15 that supplies and shuts off hydrogen gas and oxygen gas to the prongs 14 connected to the hydrogen gas supply pipe 9 and the oxygen gas supply pipe 10, and a control unit 6 that controls the opening and closing of the solenoid valve 15 based on the detection result transmitted from the detection result transmission unit 5 of the detection means 2.

[0029] As shown in Figures 1 and 6, the control unit 6 is configured to send a supply signal to the solenoid valve 15 when the user inhales, and to send a shut-off signal to the solenoid valve 15 when the user exhales.

[0030] The solenoid valve 15 is configured to open when it receives a supply signal from the control unit 6, and to shut off when it receives a shut-off signal.

[0031] Next, the mechanism of action will be explained using Figures 1, 2, and 4 through 6.

[0042] When an increase in gas pressure is detected, the detection result transmission unit 5 of the detection means 2 transmits the detection result to the supply shut-off means 3 (S10).

[0043] When the control unit 6 of the supply shutoff means 3 receives the detection result (gas pressure rise), it sends a shutoff signal to the solenoid unit 16 (S11).

[0044] When the solenoid unit 16 receives a shutoff signal, it shuts off the solenoid valve 15 (S12).

[0045] When the solenoid valve 15 is shut off, the supply of hydrogen gas and oxygen gas to the hydrogen gas supply port 7 and the oxygen gas supply port 8 is shut off, as shown in Figure 6B, and the supply of hydrogen gas and oxygen gas to the hydrogen gas supply pipe 9 and the oxygen gas supply pipe 10 is shut off (S13).

[0046] The supply of hydrogen gas and oxygen gas to the gas pressure detection pipes 11 and 18, which branch off from the hydrogen gas supply pipe 9 and the oxygen gas supply pipe 10, is shut off (S14).

[0047] The supply of inhaled gas to the user's nasal cavity from the prongs 14 connected to the hydrogen gas supply pipe 9 and the oxygen gas supply pipe 10 is shut off (S15). [Second Embodiment] The configuration of the second embodiment will be explained with reference to Figures 7 and 8.
