A process for the dynamic manufacture and packaging of gas mixtures containing a first component and a second component in predefined proportions, the first and second components being chosen from the group formed by O2,N2,He and N2O, in which predetermined proportions of the first and second components are dynamically mixed in order to obtain a gas mixture of the desired composition and the temperature of the mixture is adjusted in order to keep it above the demixing threshold temperature of the mixture. This process is particularly suitable for the production of analgesic gas mixtures that can be used in the medical field, particularly a mixture formed from 50% oxygen and 50% nitrous oxide.

1. A process for manufacturing a gas mixture containing at least a first component and at least a second component in predefined proportions, said first and second components selected from the group consisting of O2,N2,He and N2O, the process comprising the steps of: (a) dynamically mixing predetermined proportions of at least said first component and said second component to obtain a gas mixture of the desired composition; and (b) adjusting the temperature of said gas mixture containing said first and second components obtained in step (a) to keep the temperature above a demixing threshold temperature of said mixture. 2. The process according to claim 1, wherein the second component is chosen from CO2and N2O and the content of the second component is greater than or equal to 30 volume %. 3. The process according to claim 1, wherein the first component is oxygen and the second component is nitrous oxide. 4. The process according to claim 1, wherein at least one of said first and second components is in the supercritical state. 5. The process according to claim 1, wherein in step (b), the temperature of the gas mixture is adjusted to or kept above -5.5° C. 6. The process according to claim 1, wherein the temperature of the gas mixture is adjusted by warming the gas mixture by heat exchange. 7. The process according to claim 1, wherein the pressure of the gas mixture is between 120 bar and 300 bar. 8. A process for filling a container with gas comprising injecting a gas mixture containing at least a first component and at least a second component in predefined proportions into at least one container, said gas mixture being obtained by the process according to claim 1. 9. A process for filling a container with gas comprising injecting a gas mixture consisting of 50 vol % oxygen and 50 vol % nitrous oxide into at least one container, said gas mixture being obtained by the process according to claim 1. 10. The process according to claim 1, wherein the content of the second component is at least 40 volume %. 11. The process according to claim 3, wherein the gas mixture consists of 50 volume % oxygen and 50 volume % nitrous oxide. 12. A process for manufacturing a gas mixture containing at least a first component and at least a second component in predefined proportions, said first component selected from the group consisting of O2,N2,He and N2O and said second component consisting of CO2,the process comprising the steps of: (a) dynamically mixing predetermined proportions of at least said first component and said second component to obtain a gas mixture of the desired composition; and (b) adjusting the temperature of said gas mixture containing said first and second components obtained in step (a) to keep the temperature above a demixing threshold temperature of said mixture. 13. The process according to claim 12, wherein the gas mixture contains CO2and O2,and optionally helium. 14. A process for filing a container with a gas comprising injecting a gas mixture containing at least a first component selected from the group consisting of O2,N2,He and N2O and at least a second component consisting of CO2in predefined proportions into at least one container, said gas mixture being obtained by the process according to claim 12. 15. The process according to claim 13, wherein the content of CO2is at least 40 volume %.
