The anti-drowning bead string comprises an air storage micro-tank storing a high-pressure air source and a lifesaving expansion ball used for generating buoyancy, an air inflation and deflation valve is arranged on the air storage micro-tank, an air inflation and deflation port of the air inflation and deflation valve is located in the lifesaving expansion ball, and a valve body opening device used in cooperation with the air inflation and deflation valve is installed in the lifesaving expansion ball. The invention further discloses a bead chain made of the bead string. When the anti-drowning bead string is used, the anti-drowning bead string is pulled towards the two sides with force, the valve body opening device is used for opening the inflation and deflation valve, a high-pressure air source in the air storage micro tank is diffused into the lifesaving expansion ball, the internal pressure of the lifesaving expansion ball is suddenly increased, the volume of the lifesaving expansion ball is expanded, the effect of generating buoyancy is achieved, and the anti-drowning bead string can be made into a bead chain such as a necklace, a bracelet, a waist chain and an anklet to be worn. When a wearer suddenly drowns, large buoyancy can be obtained by forcibly pulling the bead chain, the operation is simple, a drowning person can be kept in a floating state as much as possible, a rescuer can also use the device, and the rescue success rate can be increased while self-protection can be achieved.

    本发明公开了一种防溺水串珠,包括存储有高压气源的储气微罐和用于产生浮力的救生膨胀球,储气微罐上设有充放气阀且其充放气口位于救生膨胀球内,救生膨胀球内安装有与充放气阀配合使用的阀体开启装置,还公开了利用该串珠制成的珠链;使用时用力向两侧拉动,利用阀体开启装置将充放气阀打开,使储气微罐内的高压气源向救生膨胀球内扩散,使救生膨胀球的内部压力骤增并使其体积膨胀,起到产生浮力的作用,可以将该防溺水串珠做成珠链如项链、手链、腰链、脚链等佩戴,佩戴者突发溺水时使用,用力拉动珠链即可获得较大的浮力,操作简单,能够使溺水者尽量保持漂浮状态,施救者也可以使用,在能够自我保护的同时提高救助成功率。
