A wearable oxygen self-rescue respirator and method of using the same

Abstract

The invention provides a wearable oxygen self-rescue respirator, comprising a breathing mask and a back clip, an oxygen supply emergency system is arranged in the back clip, and the oxygen supply emergency system and the breathing mask are connected by a breathing hose; Airbag and B airbag, A airbag and B airbag are connected through the first one-way airflow valve; carbon fiber compressed oxygen cylinder is connected with A airbag, which is equipped with CO2 absorption 2 and H 2 O and produce O 2 The chemical oxygen reaction tank of the medicine is connected with the B airbag through a porous partition; the breathing hose is wrapped with O 2 Hose and CO 2 / H 2 O hose, A air bag is connected with O through the second one-way air flow valve 2 Hose Connection, CO 2 / H 2 The O hose is connected to the B airbag through another second one-way flow valve. The invention also provides a method of using the wearable oxygen self-rescue breathing apparatus. The invention has good working performance, long oxygen supply time, light weight, convenient operation, comfortable wearing, complete functions, strong practicability, good use effect and high work efficiency.

Description

technical field [0001] The invention relates to an oxygen breathing apparatus, in particular to a wearable oxygen self-rescue breathing apparatus. Background technique [0002] Oxygen respirator is also called isolated compressed oxygen respirator. The respiratory system is isolated from the outside world, and the instrument forms an internal circulation with the human respiratory system. Oxygen is provided by a high-pressure gas cylinder, and an air bag stores the gas during exhalation and inhalation. It is widely used in petroleum, chemical, metallurgy, coal, mining, laboratory and other industries (departments), and is worn by specially trained people for rescue, accident treatment, rescue or operation in toxic and harmful gas environments (normal atmospheric pressure). use. [0003] At present, there are many problems in the design of domestic oxygen respirators, such as: eyepieces are prone to fog, resulting in unclear vision; poor quality of the mask; lack of humaniz...

AI Technical Summary

Problems solved by technology

[0003] At present, there are many problems in the design of domestic oxygen respirators, such as: the eyepiece is prone to fog, resulting in unclear vision; the quality of the mask is poor; the lack of humanized design; the material is poor, the shell is easy to break; The device has single function, complex operation, and lack of humanized design, etc., so it is often difficult for the wounded to carry out self-rescue in the first place after a mining accident, so that it causes great harm to the health of mine workers
