A portable self-rescue breathing apparatus

Abstract

The invention relates to a portable self-rescue respirator, which belongs to the technical field of fire emergency devices, and solves the problems in the prior art that the self-rescue respirator is complicated to wear and use, the breathing temperature is high, the effectiveness of the product cannot be judged, and the positioning of trapped persons is difficult. The self-rescue respirator of the present invention comprises a mouth and nose mask, a breathing tube, an oxygen generating module, an air bag, an alarm positioning unit, a housing and an oxygen generating agent; the mouth and nose mask, the breathing tube, and the oxygen generating module are connected in sequence; the oxygen generating The module includes an oxygen production tank and a four-way unit, the oxygen production tank is connected to the four-way unit, the airbag is connected to the oxygen production tank, the oxygen generator is set in the oxygen production tank; the alarm positioning unit is set in the airbag Above, the housing cover is arranged on the oxygen generating module. The self-rescue respirator of the present invention is easy to carry and use, the temperature of oxygen production is reduced, and the experience is comfortable. At the same time, it can visually determine whether the oxygen production agent is invalid. It has an alarm positioning function to facilitate rescuers to determine the position of the trapped person.

Description

technical field [0001] The invention relates to the technical field of fire self-rescue devices, in particular to a portable self-rescue respirator. Background technique [0002] When a fire accident occurs, the victims trapped at the scene can not only cover their mouths and noses with wet towels or wear filter breathing masks or compressed gas cylinder respirators, but also use chemical oxygen respirators and other means. Carry out on-site evacuation and escape for self-rescue. However, the oxygen content in the air after violent combustion is low, and the toxic and harmful components in the smoke are very complex. However, wet towels and filter breathing masks can only filter a few specific toxic gases, and it is difficult to achieve the expected filtration and purification effect. Moreover, it is also not applicable to the environment where the oxygen concentration is lower than 17%, and it is difficult to effectively guarantee the safety of escape personnel. The compre...
