Abstract
A life saving dan buoy for marine saving is revealed. The life saving dan buoy includes a strip-shaped first air bag, a second air bag disposed on a lower part of the first air bag, at least one inflation valve arranged at the first air bag and/or the second air bag for filling gas into an air chamber and allowing the first and the second air bags to expand and float over the water, and a weight. The first air bag and the second air are communicating with each other to form the air chamber. The second air bag includes an open space area that allows a user's body to get through. The weight is connected to a lower part of the first air bag so that the first air bag is standing vertically in the sea while the second air bag is floated over the sea.
