Technical Field

The invention relates to the field of life-saving supplies, in particular to a portable drowning self-rescue device.

Background

In life, drowning is a big cause of death. The drowning accident is caused by a plurality of reasons, firstly, when the accidents happen to the vehicles such as airplanes, steamships, automobiles and the like, the vehicles may fall into rivers or oceans, and passengers have no preparation when falling into water, so that drowning death is caused; secondly, in the process of the water operation project, personnel are required to wear the life jacket, but the life jacket is too heavy, which causes great inconvenience for the work of the wearer, so that in the water operation process, the personnel often don't wear the life jacket, and the life jacket is drowned and died after falling into water accidentally; thirdly, some teenagers like to play in rivers or seasides, and drowning accidents are easy to happen.

The current life-saving equipment for preventing drowning is mainly life buoys and life jackets. The lifebuoy occupies a large space and is inconvenient to carry, so that the lifebuoy is thrown to personnel falling into the water by rescue personnel after the personnel fall into the water, and the lifebuoy cannot be obtained smoothly and timely by the aid of the lifesaving method, so that the lifebuoy is not reliable enough. The life jacket is also a common life-saving device, but the life jacket often causes inconvenience for work or entertainment of a wearer, so that a water operator does not wear the life jacket according to the specification, and a water player often does not wear the life jacket, so that the life jacket cannot play a role of drowning prevention.

The utility model discloses a fall into water device of saving oneself is disclosed in chinese utility model patent publication No. CN107128464A, including aerifing module, gasbag module and ventilation zone, aerify the module and include gas generating device and the control unit, the control unit with gas generating device is connected, and the gasbag module includes gasbag and gasbag storehouse, and the gasbag is folded in the gasbag storehouse, the ventilation zone is equipped with gas passage, gas passage intercommunication gas generating device and gasbag, gas generating device are acid-base reaction air feeder, and acid-base reaction air feeder includes interior cavity and outer cavity for deposit respectively mutual reaction and can emit gaseous chemical reagent, the control unit is used for realizing saving oneself device functional mode setting, falls into water automatic control or manual control, including mode switch, start button, outer box, floating plug and mechanical needle.
