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.
