Description

Wearable underwater lifesaving device

Technical Field

The invention belongs to the technical field of lifesaving devices, and particularly relates to a wearable underwater lifesaving device.

Background

Lifesaving devices are devices for rescuing people from predicaments at crisis, such as lifesaving hammers on buses, fire extinguishers and AEDs in public places, lifebuoys provided by cruise ships and swimming pools, and the like are regarded as generalized lifesaving devices.

Taking underwater rescue as an example, rescue ships, life buoys, life jackets and other equipment can provide safety first-aid guarantee when people drown or other emergencies, and harm is reduced to the maximum extent. However, the rescue ship is huge in size, needs to be operated by people, is high in manufacturing cost, high in rescue threshold and low in rescue efficiency, and cannot achieve the purpose of on-site rescue in time after a danger occurs. The life buoy is inconvenient to carry, belongs to an auxiliary object of a rescue ship in most of the time, and cannot provide good help under the condition that the use condition is limited by the rescue time of the rescue ship. The life jacket needs to be worn in advance, and is not beneficial to the activity of a wearer after being worn, so that the wearing experience is very poor.

Therefore, people invent the life-saving device capable of being worn on the body, the life-saving device can be worn on the wrist or other positions of four limbs like a bracelet, when the situations such as drowning, cramping and the like occur, the air bag can be popped out only by triggering the life-saving button on the life-saving device, so that the human body can float to the water surface in a short time, then the arrival of subsequent rescue personnel can be waited, and valuable time is won for implementing safer rescue.

However, the disadvantage of this kind of life saving device is that the wearing part is the limbs, especially the wrist, so after releasing the air bag, the strong buoyancy generated by the air bag can limit the movement of the arm or other limbs wearing the life saving device in water. Therefore, once the life-saving device is triggered, the human body can only float on the water surface to wait for rescue, and is difficult to separate from the current water area. It will be seen that there is room for further improvement in such life saving devices.
