Positive-pressure closed-circuit temperature-adjusted oxygen respirator

Abstract

The invention discloses a positive-pressure closed-circuit temperature-adjusted oxygen respirator, which comprises an oxygen supply part and an accessible communication part, wherein the oxygen supply part comprises an oxygen storage cylinder, a manual / automatic oxygen supply valve, a breathing gas bag, an emergency system, a temperature reduction system capable of adjusting the temperature, a CO2 filtering system, a breathing mask, a quantitative supply valve, a refrigerant filling switch, a refrigerant release switch, an exhaling pipeline, an inhaling pipeline, a quantitative supply pipeline and a manual / automatic compensation pipeline, wherein the breathing mask, the exhaling pipeline and the inhaling pipeline are positioned outside a housing of the oxygen respirator, and the other parts are positioned in the housing of the oxygen respirator. The positive-pressure closed-circuit temperature-adjusted oxygen respirator can be used by a single person under a high-temperature oxygen-deficient environment, be used for providing sufficient oxygen in an appropriate temperature for a user, and realize accessible communication among field staff and the accessible communication with a command center.

Description

technical field [0001] The invention belongs to an oxygen breathing device, in particular to a positive pressure closed-circuit temperature-adjustable oxygen breathing device. Background technique [0002] The oxygen respirator uses the oxygen storage container carried by itself to store oxygen at high pressure, and decompresses the oxygen to the use pressure during use for supplementary use. The working process of the oxygen respirator device is that the exhaled exhaust gas passes through the pipeline and enters the CO 2 Filtration system (oxygen regeneration system) to make CO 2 Reacts with chemicals in the system, exhaling CO in the breath 2 Filter out and generate a lot of heat. After a long period of use, the heat generated by the chemical reaction will raise the temperature of the gas to a high temperature that the human respiratory system cannot withstand. In order to enable the operator to work normally, the oxygen respirator device has taken the following coolin...

Problems solved by technology

[0004] The purpose of the present invention is to provide a positive pressure closed-circuit temperature-adjustable oxygen respirator, which can not only realize the adjustable temperature of the breathing gas, but also solve the problem of always paying attention to the remaining gas pressure and the inability to communicate normally with the site and the outside world, thereby To achieve the purpose of being able to operate conveniently for a long time in a high temperature and hypoxic environment, and at the same time carry out barrier-free communication
