WATER RESCUE DEVICE

摘要

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.

1. A water rescue device, comprising: an air chamber configured to become hollow and tubular when filled with gas; 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.
