Definitions
- the invention relates to pure oxygen or oxygen-containing gases with added fragrances.
- Pure oxygen is stored as compressed gas in pressurized gas containers or as refrigerated gas in insulating containers and used, for example, for breathing gas in medicine and fitness.
- gas mixtures with an oxygen content of more than 20 vol.% are used, e.g. B. oxygen-nitrogen mixtures with 50 vol.% Oxygen.
- the object of the invention is to provide oxygen-gas mixtures which are perceived as pleasant when inhaled.
- the object of the invention is thus an oxygen-gas mixture with the features of claim 1.
- oxygen gas In the following pure oxygen or oxygen-containing gas mixtures with more than 20 vol.% Oxygen is referred to as oxygen gas.
- An oxygen source is a compressed oxygen-containing gas, in particular compressed pure oxygen, or a cryogenic oxygen-containing gas such as liquid oxygen.
- a fragrance is added to the oxygen gas for perfuming or aromatizing.
- Fragrances or flavors are usually gaseous or volatile liquid or volatile solid compounds, usually fragrances are considered Mixtures of different fragrances are used (e.g. as a fragrance concentrate). Fragrances are, for example, essential oils which generally contain terpenes.
- the fragrances are preferably used to generate a fragrant oxygen gas.
- the fragrances can also have a physiological or other advantageous
- menthol has a deodorant effect. Treating the airways with menthol is particularly beneficial.
- Fragrances are generally natural, semi-synthetic or fully synthetic substances. Natural fragrances are e.g. B. peppermint oil, lavender oil, rose oil,
- Patchouli oil clove oil.
- Natural fragrances are preferably produced by extraction in supercritical gases, in particular carbon dioxide, and used in these gases.
- Perfumed oxygen gas is particularly advantageously produced with fragrance or fragrances in carbon dioxide as the inert gas.
- Inert gases such as carbon dioxide, nitrogen and noble gas such as helium, argon, neon, xenon or krypton are preferably used to produce perfumed oxygen gas.
- Perfumed oxygen gas is preferably produced by metering fragrance, that is to say one or more fragrances, in a pressurized gas container with an inert gas cushion and then diluting it with oxygen gas by pressing it on to 50 to 300 bar.
- the oxygen gas can contain physiologically active substances, such as terpenes or other active constituents such as essential oils, the therapeutic or stimulating, positive effect on the human organism is known from medicine, and can thus be administered by inhalation in a simple manner in therapy or self-medication.
- physiologically active substances such as terpenes or other active constituents such as essential oils
- the fragrance is preferably a mixture and contains esters, aldehydes, ketones, alcohols, lactones, terpene hydrocarbons and / or essential oils.
- Especially preferred fragrances contain esters, generally 30 to 70% by volume (based on the total amount of the fragrance), in particular 30 to 60% by volume.
- These fragrances and fragrance mixtures are usually liquid at room temperature.
- the mixture of fragrance and oxygen gas is preferably produced using a metering process, the fragrance first being metered into an inert gas.
- the so-called "soft dosage" of fragrance in an inert gas supply (nitrogen, carbon dioxide or noble gases) of a few mbar or bar pressure is surprisingly suitable, long-term stable mixtures in compressed gas containers, in particular made of aluminum, with about 0.1 to 150 mg / m 3
- Fragrance or fragrance recipes 0.5 to 30% inert gas, e.g. B. nitrogen or helium, rest of oxygen with 100 to 300 bar total pressure.
- inert gas e.g. B. nitrogen or helium
- the final preparation of the mixture is carried out either by pressing on further inert gas (production of a premix in inert gas for further metering of daughter mixtures with oxygen) or by high-pressure oxygen.
- fragrances For perfuming oxygen gas, compounds which are stable to oxidation are used as fragrances, such as esters (e.g. ethyl acetate, organic esters) or ethers such as diphenyl ether or t-butyl methyl ether.
- esters e.g. ethyl acetate, organic esters
- ethers such as diphenyl ether or t-butyl methyl ether.
- the fragrances used preferably contain no oxidation-sensitive solvents such as ethanol.
- the solvent content of the fragrances is preferably low, e.g. B. 0.1 to 1 vol .-% or lower.
- Perfumed liquid oxygen is produced, for example, by adding liquid, preferably cooled, perfume or perfume concentrate to the liquid oxygen.
- the fragrance or the fragrance concentrate is preferably placed in liquid nitrogen and the liquid oxygen is added.
- Fragrance concentrates are e.g. B. the most diverse perfume oils.
