Abstract
When carrying out a water emergency rescue, to rescue, particularly from a helicopter, a plurality of victims in a wide area of water without any drowning occurring. [Solution] A water rescue device is formed from: a hollow tube-shaped air chamber which is stored in an evacuated state; a gas injection mechanism which injects a pressurized gas in the air chamber; a pressurized gas tank which retains the pressurized gas; and a case which houses the air chamber, the gas injection mechanism, and the pressurized gas tank. When the case is lowered upon a water surface from a helicopter, the pressurized gas in the pressurized gas tank is injected via the gas injection mechanism into the air chamber, and the air chamber is released from the case, expanded in a swirl shape, and deployed on the water surface.
Claims6
A water rescue device, comprising:
- an air chamber, which is configured to become hollow and tubular when filled with gas, and which a rescuee can hold on to;
- a gas filling mechanism adapted to fill the gas into the air chamber;
- and
- a compressed gas cylinder adapted to compress and hold the gas,
- wherein the compressed gas from the compressed gas cylinder is filled into the air chamber by the gas filling mechanism, unfolding the air chamber into a spiral shape,
- wherein when inflated by being filled with gas, the air chamber has a hollow tubular shape with a substantially circular cross section and without a partition.
