The invention discloses an air-drop lifesaving device. The air-drop lifesaving device comprises an upper raft body and a lower raft body, wherein the upper raft body and the lower raft body are folded and placed in a waterproof wrapping piece to be released; when the lifesaving device is airdropped by an airplane, the lifesaving device can be unfolded in the air, and after landing, the raft body can be automatically unfolded and inflated to be formed; the connecting rope is connected to the upper raft body and the lower raft body, and the upper raft body and the lower raft body are connected into a whole through the connecting rope. The raft body piece and the connecting piece are striking in color, can emit light to indicate positions, and can be easily found by people in distress when floating on water. After being air-dropped into water in a windward area of a person in distress, the device can be linearly distributed on the sea surface, traditional point-to-point rescue butt joint that the person in distress needs to swim to a lifesaving device is changed into line-to-point rescue butt joint that the lifesaving device covers the person in distress in a linear mode, and rescue butt joint can be rapidly achieved. The rescue device can float to persons in distress under the action of sea surface stormy waves, so that the physical strength of the persons in distress in rescue docking is effectively saved, and the rescue success rate is greatly increased.

本发明公开了一种空投救生装置，包括：上筏体和下筏体均折叠放置在防水包裹件内待被释放；救生装置由飞机空投时，救生装置能够在空中展开，着水后，筏体能够自动展开充气成型；连接绳连接在上筏体和下筏体上，连接绳将上筏体和下筏体连接在一体；筏体件和连接件颜色醒目，能够发光示位，在水上漂浮时，易于为遇险人员发现。在遇险人员上风区域空投着水后，可在海面呈线性分布，将传统的需要遇险人员游向救生装置的点对点救援对接，变为救生装置以线状覆盖遇险人员的线对点的救援对接，有利于快速实现救援对接；借助海面风浪作用，救援装置可飘向遇险人员，将有效节省救援对接中遇险人员体力，大幅度增加了救援成功率。
