An inflation device for storing and releasing pressurized fluid includes a substantially donut shaped cylinder (2) containing the pressurized fluid. An activation system (4) includes a trigger mechanism (6) positioned within a cavity (8) formed by the donut shaped cylinder (2). The cylinder (2) includes at least one puncturing zone (3) in contact with the pressurized fluid, the puncturing zone (3) including a sealing element (33) seated on a valve member inside the puncturing zone (3), the sealing element (33) connected to a puncturing rod (31). When activated, the trigger mechanism (6) actuates the puncturing rod (31), driving the sealing element (33) off the valve member thereby allowing the pressurized fluid to flow out of the cylinder (2) past the sealing element (33) and through the puncturing zone (3).
