  • Patent number: 10596344
    Abstract: An anesthesia device configured to measure the hydrogen concentration in an anesthesia gas containing a hydrogen gas includes: an anesthesia gas preparation circuit configured to generate anesthesia gas by mixing an air or an oxygen mixture air with a vaporized anesthetic; a closed circuit-type or semi-closed circuit-type respiratory circuit including a gas circulation passage configured to circulate the hydrogen-containing anesthesia gas containing the hydrogen gas and the vaporized anesthetic; and a hydrogen concentration measurement circuit configured to measure the hydrogen concentration in the hydrogen-containing anesthesia gas in the gas circulation passage, wherein the hydrogen concentration measurement circuit includes: an anesthetic removing member having a removability of the vaporized anesthetic in the hydrogen-containing anesthesia gas; and a hydrogen concentration measuring instrument provided on the secondary side of the anesthetic removing member.

  • Publication number: 20190015446
    Abstract: [Problem] To provide a medicinal composition that is capable of improving the prognosis after the restart of the patient's own heartbeat even after the passage of a considerably long period of time after the restart of the patient's own heartbeat. [Solution] A gaseous medicinal composition for improving the prognosis alter the restart of the patients own heartbeat, said medicinal composition being to be administered to a human subject after the passage of at least 30 minutes after the restart of the patient's own heartbeat following cardiorespiratory arrest for at least 10 minutes. The medicinal composition according to the present invention, which contains hydrogen gas, is characterized in that a group of human patients administered with the medicinal composition shows improved prognosis after the restart of the patient's own heartbeat compared with another group of human patients not administered with the medicinal composition.

  • Patent number: 8900540
    Abstract: An oxidation treatment method of the present invention includes the step of bringing a solution having an ozone concentration of 120 to 500 mg/L into contact with a substance to be treated made of a combustible substance, thereby subjecting the substance to be treated and the surface thereof to an oxidation treatment. An oxidation treatment apparatus of the present invention includes: a dissolving means that dissolves an oxygen-ozone mixed gas in a fluorine-based solvent to form mixed fluid; an undissolved gas removal means that removes an undissolved gas from the mixed fluid to form a solution; and an oxidation treatment means that brings the solution into contact with a substance to be treated made of a combustible substance, thereby subjecting the substance to be treated and the surface thereof to an oxidation treatment.

  • Publication number: 20100322844
    Abstract: An ozone supplier 11 of the present invention includes a mixer 1 which dissolves an oxygen-ozone mixed gas in a fluorine-based solvent to produce a mixed solution, an undissolved gas removing device 2 which removes an undissolved gas from the mixed solution, and a deaerator 3 which extracts an ozone-containing gas, which is dissolved in the mixed solution subjected to removal of the undissolved gas, from the mixed solution.
