The invention discloses an emergency oxygen supply device, which belongs to the technical field of emergency lifesaving equipment. It includes an oxygen production module, a cooling, humidification and impurity removal module, a buffer module, a gas proportioning module, a gas delivery module, and a positioning display module. , the buffer module is communicated with the gas proportioning module. The advantages of the present invention lie in that, compared with the prior art: first, the oxygen production reaction rate and process of the present invention are controllable, so as to meet people's needs for oxygen supply speed under different physiological states; secondly, the present invention is provided with cooling, humidifying, and impurity removal. The gas generated by the module has high safety and comfort; thirdly, the present invention can be used for emergency oxygen supply for comatose people by setting the gas proportioning module; finally, the present invention can accurately locate, facilitate the rescuer to lock the position of the device, and start rescue in time. |
