DESCRIZIONE
A kind of lifesaving platform, including two flexible outer sheet materials (4,5), each outer panel have round edge (2), and two outer panels are sealed together at their round edge, to form gap (18) between two outer panels；The lifesaving platform further includes the interior flexible sheet material (6) being inserted between described two outer panels (4,5), and the gap is divided into two sub- gaps (18a, 18b) by the interior flexible sheet material；And the device (8) for lifesaving platform inflation, described device is by introducing gases into the gap to increase gas pressure therein come for lifesaving platform inflation, wherein, the Inner panel (6) is arranged to, so that if the outer panel (4,5) one in ruptures at breach, gas pressure in that described gap will tend to that the Inner panel (6) is pushed to pass through the breach, to block the breach, and reduce the amount for the gas run out of by the breach.
