This is a water surface first aid device, used to rescue potential drowning people in time, mainly including first aid devices and smart bracelets. The first aid device is interconnected with the bracelet worn by the user within a certain range. In case of emergency situations such as cramps in water or straying into deep water area, the bracelet can monitor the abnormal heart rate of the user or use the active call for help function. At this time, the Lifeguard can reach the person who falls into the water through the positioning system in the first time after receiving the signal, and the person who falls into the water can be brought back to the shore. This method is more efficient and safer than manual rescue. On the one hand, it can reduce the risk of drowning caused by physical exhaustion or cramps when swimming, and on the other hand, it can also reduce the casualties of rescuers. In addition, a light is installed in front of the rescue device, which can make the person who fell into the water notice the position of the device during night rescue through the light. When returning to the shore, the person who fell into the water can change the light through the button on the handle, so that the personnel on the shore can notice the rescue situation., To provide help for those who fell into the water.
