The invention is suitable for the technical field of daily necessities, and provides a lifesaving device, a life buoy and a lifesaving method. The lifesaving device comprises an air bag structure used for containing air in a sealed mode, forming a hollow structure and generating buoyancy to lift a bearing object, a water absorption assembly being communicated with the external environment and hermetically communicated with the air bag structure, and a chemical reagent; the water absorption assembly deforms and recovers under the action of external force, a negative pressure structure is formed through the recovery of the volume change of the water absorption assembly, and external water is sucked in; the chemical reagent is contained in the air bag structure or the water absorption assembly and chemically reacts with water absorbed by the water absorption assembly to generate gas, and the air bag structure is filled with the gas; a one-way valve capable of preventing gas from flowing out is arranged in the water absorption assembly and allows water and gas to flow in. The device has the advantages of being simple in structure, convenient to operate, light in weight, small in size, low in manufacturing cost, high in safety and convenient to popularize and implement.

    本发明适用于日用品技术领域,提供了一种救生装置、救生圈以及救生方法。所述救生装置包括:气囊结构,用于对气体进行密封盛放并形成内空结构,产生浮力托举承载物;吸水组件,连通外部环境并密封的与所述气囊结构连通,所述吸水组件通过外力作用产生形变和恢复,通过吸水组件容积改变恢复形成负压结构,将外部的水吸入;化学试剂,盛放在所述气囊结构或者吸水组件的内部,与所述吸水组件吸入的水进行化学反应,产生气体并充斥到所述气囊结构内部;所述吸水组件内部设置有可阻碍气体流出的单向阀,单向阀允许水和气体流入。本发明优点:结构简单,操作方便,质量轻,体积小,制造成本低,安全性高,便于推广实施。
