Description

technical field [0001] The invention relates to a water life-saving device, in particular to a portable water life-saving device. Background technique [0002] According to the World Health Organization, an estimated 360,000 people died from drowning in 2015 alone. Drowning is often caused by emergencies, including problems with one's own physical condition, accidental falling into the water, encountering floods, encountering shipwreck, etc. When victims encounter danger, they lack effective rescue tools. Large, heavy, single function and other shortcomings. In order to overcome these defects, a series of portable water life-saving devices have been developed, such as Chinese patent CN105460181B discloses a kind of portable water life-saving device, utilizes a compressed air tank to inflate an inflatable life buoy; Chinese patent CN106043628B discloses a portable water life-saving ball, The elastic bag is inflated by using the gas and foam generated by the reaction of the ...

Problems solved by technology

For example, when the person who fell into the water floats on the water using portable life-saving equipment, he lacks effective tools to form a connection with the person in the safe zone, so that the person in the safe zone can pull him to the safe zone; After the equipment floats on the water, he lacks effective tools to help other drowning persons nearby; for another example, when someone falls into the water, it is difficult for rescuers to pass the lifesaving equipment to the drowning person. Those who fell into the water, but the weight of the life-saving equipment is heavy, the manpower is limited, and the throwing distance of the life-saving equipment is limited, so it is impossible to help those who fall into the water at a long distance; Waiting for rescue. According to relevant news reports, people who fell into the water gather together to help each other and rescue them.
