Description

Technical Field

[0001] The utility model relates to the technical field of underwater rescue, in particular to a life-saving device used for underwater emergency. Background Art

[0002] Water sports are a sport that most people enjoy, such as surfing, sailing, swimming, fishing, etc. They can not only exercise the body, but also bring the fun of playing in the water to participants. However, water-related activities generally have the risk of drowning, especially for children, the elderly and the weak, and those who are not good at swimming. Once a drowning situation occurs, if they are not discovered and rescued in time, they are likely to drown, especially in the case of freestyle swimming. Once drowning occurs, they can only rely on outsiders or external forces to carry out rescue, and they cannot save themselves, resulting in such tragedies every year. In addition, in the process of lifesaving, due to long-term immersion in water, they will become weak, which is not conducive to the rescue of personnel. For this reason, we propose a life-saving device for underwater emergency. Utility Model Content
