Puncture device for an inflatable unit

A method for transferring gas from a pressurized gas cylinder to an inflatable unit through a gas management device having a gas inlet, a gas outlet and a puncture device, the method comprising:

• securing a casing of a vessel to the gas inlet of the management device,
• securing the inflatable unit to the gas outlet of the management device,
• providing a pyrotechnical detonator having an igniting stimuli and an explosive charge arranged adjacently to the gas inlet as a part of the puncture device,
• activating the igniting stimuli of the pyrotechnical detonator to create a shock wave to puncture the casing of the vessel, and
• creating a gas channel between the gas inlet and the gas outlet when the puncture device is activated.

A system for inflating an inflatable unit including a pressurized vessel, said inflatable unit and said pressurized vessel being secured to a management device, the system comprising:

• a gas inlet to which a casing of the pressurized vessel containing pressurized gas is secured,
• a gas outlet to which an inflatable unit is secured, and
• a puncture device for puncturing the casing, whereby gas from the vessel is directed to the inflatable unit,
• wherein said puncture device includes a pyrotechnical detonator having an igniting stimuli and an explosive charge arranged adjacently to the gas inlet, said igniting stimuli being configured to emit energy when activated, such that the energy activates the explosive charge to create a shock wave which punctures the casing of the vessel, and said pyrotechnical detonator being configured to create a gas channel between the gas inlet and the gas outlet when the puncture device is activated.
