The present invention relates to a gas management device 10; 20; 30; 40; 50 comprising: a gas inlet 11; 32; 42; 52 adapted to secure a casing of a vessel 22, preferably a closure 26 sealing an opening of a gas cylinder containing pressurized gas; a gas outlet 12; 33; 43; 53 adapted to be secured to an inflatable unit 23; and a puncture device 10b; 31b; 41b; 51b for puncturing the casing of the vessel 22. The puncture device 10b; 31b; 41b; 51b comprises a pyrotechnical detonator 16 that, when activated, creates a chock wave which punctures the casing of the vessel 22, whereby gas from the vessel 22 is directed to the inflatable unit 23. The invention also relates to a method and a system for transferring gas from a pressurized vessel to an inflatable unit via a gas management device.
