Rebreathing apparatus having inhaled oxygen mixing and exhaled carbon dioxide removal functions by electronic control

Abstract

The invention relates to a rebreathing apparatus having inhaled oxygen mixing and exhaled carbon dioxide removal functions by electronic control. The rebreathing apparatus includes a mask formed in response to a face of a user and having one side to which an inhalation hose is connected and the other side to which an exhalation hose is connected; an exhaled breath storing container storing exhaled breath discharged from the exhalation hose; a filter unit removing carbon dioxide discharged from the exhaled breath storing container; an inhaled breath storing container storing the air having passed through the filter unit and being connected to the inhalation hose of the mask; an oxygen storing container configured to supply oxygen through an oxygen supplying hose to the inhalation storing container; a decompressor installed at an inlet of the oxygen storing container, the decompressor being configured to block the oxygen of high pressure from being discharged. The rebreathing apparatus may be electronically controlled by using multiple sensors to provide an integral breathing mechanism by removing exhaled carbon dioxide, mixing oxygen using an oxygen mixing module, and supplying the mixedoxygen to the breath.

Description

technical field [0001] The present disclosure relates to an electronically controlled rebreather with inhaled oxygen mixing and exhaled carbon dioxide removal. More specifically, the present application relates to a breathing apparatus for breathing in which an oxygen mixing module is used to maintain the amount of oxygen inhaled through breathing while removing carbon dioxide released through breathing out. Background technique [0002] Unless otherwise indicated in this specification, the information described in this section is not prior art to the claims in this application and is not admitted to be prior art by inclusion in this section. [0003] Disasters create heat, flames and toxic fumes that put people at risk. It is currently known that, 2 to 5 minutes after a fire, most of the dangerous situations are caused by toxic gases and smoke. [0004] Respirators are therefore required to protect people from these hazards. Lifeguards (firefighters) need to wear respira...

AI Technical Summary

Problems solved by technology

[0010] refer to its published figure 1 , which shows a conventional SCBA for 119 firefighters, which consists of masks and oxygen cylinders, due to its weight of about 13kg, it is difficult to perform a smooth rescue operation, which usually takes about 60 minutes, and it has only continuous Disadvantages of use

In addition, since the concentration control function of breathing oxygen is not included, the oxygen concentration provided to the user's breath cannot be determined, and since it does not support the sensor network function and operates only through SCBA, it cannot communicate with various smart devices or the central control center
