Lifesaving Whistle / Lifesaving Whistle

lifesaving whistle is made of plastic as a whole. The body is made as a ring shape to form a plastic and elastic ring. The ring-shaped whistle can make a clearer sound.
Before jumping into the water, the lifeguards can quickly apply the whistle to clamp their noses to avoid inhauling water when diving.
When the lifeguards are doing artificial respiration for the drowned, oral base of the tongue or neck posture often impede the smooth flow of the respiratory tract. Our ring-shaped whistle can be used as a shaper to assist to open the tongue base and the respiratory tract of the drowned. So that the drowned can be better rescued
