When swimming people encounter cramps in water, or physical overdrawing caused by too long distance of swimming, or when swimming in rivers and seas encounters vortexes and waves, or when physical potential causes such as heart disease and hypertension and other diseases burst, and the like, the conditions are extremely easy to cause drowning.

Therefore, a self-rescue device capable of timely opening the power supply of the air pump to inflate and enabling the head of the self-rescue device to float out of the water surface to wait for rescue and achieve the drowning prevention effect is needed. The device is manufactured into wearable swimwear, is not different from the swimwear in normal times, and can be used for exposing the head and the upper body of the device to the water surface to wait for rescue or can be used for swimming to the bank by means of buoyancy by itself once the device is opened in time in case of dangerous situations.
