Description

Inflatable marsh life vest

Technical Field

The invention relates to the technical field of marsh lifesaving appliances, in particular to an inflatable marsh lifesaving vest.

Background

Swamp refers to the soil where the soil on the surface and the subsurface is often over-wet, wet plants and swamp plants grow on the surface, and there is peat accumulation or there is no peat accumulation but a submerged layer. If people accidentally fall in a deep puddle dangerous situation, trapped people can get deeper and deeper due to the action of gravity, and the trapped people can not get rid of danger and get deeper and deeper only by struggling by themselves. The inflatable life vest in the current market takes the buoyancy of a small inflatable air bag as a life-saving means. The buoyancy of the inflatable air bag is weak, the inflatable air bag is only used for emergency when falling into water, and the life safety cannot be guaranteed when falling into water for a long time, so that the inflatable air bag is limited in adaptation to the environment. The marsh is generally located in the field, for trapped people in deep marsh, the time for waiting for rescue is often longer, the trapped people can get deeper and deeper under the action of gravity, and even life danger occurs, but the buoyancy of the existing life vest is limited, so that the trapped people can not escape before rescue teams arrive, and therefore, an inflatable marsh life vest which can be used for self rescue of the trapped people needs to be designed.
