The invention discloses an underwater emergency lifesaving respirator, which is characterized in that a ventilation floating ball containing cavity is cylindrical, the outer layer of the ventilation floating ball containing cavity is wrapped with a shell of a floating material, a plurality of air guide branch pipes are arranged at the top end of the ventilation floating ball containing cavity and obliquely stretch into the ventilation floating ball containing cavity, the outer contour of a ventilation floating ball is in an inverted eggplant shape, and openings of the air guide branch pipes are exposed out of the water surface all the time. One end of a breathing main pipe penetrates through the center of an air bag tray and extends into a check ring arranged at the top end of the ventilation floating ball containing cavity, and the other end of the breathing main pipe is provided with a breathing mouthpiece, a nose clip and an anti-disengaging elastic band. During breathing, air enters the ventilation floating ball containing cavity from the air guide branch pipe and then enters the breathing main pipe and the breathing mouthpiece, and water entering the ventilation floating ball during breathing can be discharged in time through the air guide branch pipe. The safety can be improved through the arranged air bag tray. A drowning person can float on the water surface for a long time.

    本发明公开了一种水中应急救生呼吸器,包括:所述换气浮球容腔呈圆柱形,外层包裹漂浮材料的外壳,换气浮球容腔顶端设置多根导气支管斜向伸进内部,换气浮球外轮廓呈倒茄子形,使导气支管口始终露出水面。呼吸主管一头穿过气囊托盘中心,伸进换气浮球容腔顶端所设置的挡圈内,呼吸主管另一头设置呼吸咬嘴、鼻夹、防脱松紧带。呼吸时空气从导气支管进入换气浮球容腔,再进入呼吸主管和呼吸咬嘴,呼吸中进入换气浮球内的水会通过导气支管及时排出。设置的气囊托盘更能增加安全性。使落水者长时间浮于水面。
