A wearable underwater lifesaving device

Abstract

The invention provides a wearable underwater lifesaving device, which belongs to the technical field of lifesaving devices, and in particular relates to a wearable underwater lifesaving device. The problem that the existing lifesaving device is difficult to stay away from the existing water area is solved. It includes a device body and a strap. The device body includes a casing, a cover, a material bullet and an air bag. Two first partitions arranged in parallel are arranged inside the casing, and a second partition is connected between the two first partitions. Two partitions, through two first partitions and second partitions, the inside of the shell is divided into a reaction chamber, a storage chamber and two insertion chambers, the first partition is provided with a sharp part, and the There are two material bombs, which are respectively arranged at the two insertion cavities and connected with the shell. The two material bombs are respectively loaded with material bags, and the contents of the two material bags react to generate gas to inflate the air bag. It is mainly used for underwater lifesaving. It is worn on the chest of the user, which frees the limbs, shortens the waiting time for rescue, and greatly improves the lifesaving efficiency.

Description

technical field [0001] The invention belongs to the technical field of lifesaving devices, in particular to a wearable underwater lifesaving device. Background technique [0002] Life-saving devices are a type of device that saves people in times of crisis. For example, life-saving hammers on buses, fire extinguishers and AEDs in public places, and life buoys provided by cruise ships and swimming pools are all considered life-saving devices in a broad sense. [0003] Taking underwater rescue as an example, rescue ships, life buoys, life jackets and other equipment can provide safety and first aid protection in the event of drowning or other emergencies, minimizing hazards. However, the rescue ships are bulky and need to be operated by people. The cost is high, the rescue threshold is high, and the rescue efficiency is low. They cannot reach the scene in time to carry out rescue after the danger occurs. And buoy buoy is then not easy to carry, and most of the time belongs to...

Problems solved by technology

[0005] However, the disadvantages of this type of life-saving device also exist. Because the wearing part is the limbs, especially the wrist, after the air bag is released, the strong buoyancy generated by the air bag will limit the movement of the arm or other limbs wearing the life-saving device in the water.

Therefore, once the life-saving device is triggered, the human body can only float on the water surface and wait for rescue, and it is difficult to get out of the current water area
