The invention discloses a rescue wristband used for detecting drowning and sending out a rescue signal. The rescue wristband comprises a shell, wherein a closed air bag cavity is formed in the shell;an air bag spraying device is arranged in the air bag cavity; the air bag spraying device comprises an air valve; and the air valve is fixedly arranged on the inner wall of the lower side of the air bag cavity. A device for detecting water is arranged in the rescue wristband; after water is detected, a water pressure detection device is started; work is resumed only when the water pressure detection device and the water pressure detection device meet conditions at the same time, so work errors caused by misjudgment under accidental conditions are avoided; the rescue wristband is internally provided with a high-pressure air inflation device, an air bag is inflated after drowning is detected, and therefore, the air bag floats upwards to drive a smoke device to float upwards, smoke is released, and rescue is facilitated.
本发明公开了一种用于落水检测发出救援信号的救援手环,包括外壳,所述外壳内设有封闭气囊空腔,所述气囊空腔内设有气囊喷雾装置,所述气囊喷雾装置包括气阀,所述气阀固定设置在所述气囊空腔下侧内壁上,本发明内置检测水的装置,在检测有水后,再开启水压检测装置,两者条件同时达到,工作才继续进行,避免偶然条件下的误判,导致工作出错,并且装置内置高压气充气装置,再检测到落水后,给气囊充气,从而使得气囊上浮,带动烟雾装置上浮,从而放出烟雾,方便救援。
