Description

Multifunction Chamber for human life protection

The present invention relates to a multi-functional chamber for protecting human life. The fire protection apparatus comprising a hepa filter and a carbon filter forms a closed chamber while preventing a contact with polluted air in the air in case of fire, chemical and other natural disasters. It cleans the inlet air and protects the human life in the closed chamber, and supplies oxygen when there is insufficient oxygen concentration in the inlet air, and makes contact with air in the air (oxygen concentration; 19.5-20.5%) by the closed chamber. The oxygen supplied from the oxygen generator to maintain high oxygen (30-35%) inside the chamber by the oxygen concentration controller, and the carbon dioxide, dust, and odor generated from the user by the carbon dioxide controller. Multi-functional chamber for human life protection by removing through filter and carbon filter to protect human life, rest and work It relates.

In general, the life-saving protection facilities for large buildings or public facilities in the case of fire, fire and other disasters or other natural disasters are listed in Korea and abroad, but they are common protection facilities used by many (more than ten people). There are no protection facilities for domestic life at home and abroad. In addition, the common protection facility is not equipped with most of the CBR purifier, even if a part is installed, oxygen is temporarily dissipated in the atmosphere due to the oxygen shortage in the surrounding air during the fire or the use of a vacuum bomb as a new technology weapon during the CBR. In this case, even if the pollutants are purified by the NBC purification device and non-hazardous air is introduced, oxygen may be insufficient in the inlet air (no more than 8% of the oxygen in the air and more than 4 minutes of life risk). In the state there is a limit to the protection of life.

In addition, the common protective facilities had no solution when a patient to be treated with high oxygen, such as respiratory disease, hypertension, in the evacuation facility.

In addition, since the common protective facilities are installed only in a specific area such as the underground which is not well known to the general public, there will be a limit to use when there is a short time to evacuate in case of fire, chemical or other natural disasters.

In addition, oxygen spray, oxygen cafe, oxygen bar, etc., which are facilities for improving health using oxygen, are inconvenient for the user because they are directly inhaling oxygen through a suction mask and a hose nose injection due to the special characteristics of oxygen. Primitive oxygen supply method can not supply the proper amount of oxygen, but there is a limit that can cause adverse effects such as oxygen poisoning by over-intake of oxygen. In other words, the reason for inhaling oxygen directly is that the oxygen concentration in the atmosphere immediately after contact with air in the atmosphere even if a large amount of oxygen (e.g., 80% or more concentration) is generated through the oxygen generator due to the characteristics of oxygen. This is because there is a characteristic of distribution (dissipation) to (19.5-20.5%).

Some personal oxygen capsules are used both domestically and internationally to recover from fatigue and promote health, but there are no CO2 purifiers to protect human life in case of fire, NBC or other natural disasters. As there is no function to remove the back, the user inhales carbon dioxide (indoor standard; 1000ppm) in a confined space, which will be harmful to the user's health, and thus there is a limit to use.

In addition, the existing oxygen capsules are lying in a narrow space (horizontal type) to use, it will not be able to work except for a short sleep. Moreover, the existing oxygen capsules have an average equipment space (length; 2.1mx width; 1m or more) of 2.1m2 or more, and the installation and entry space (length; 2.5mx width; 2.1m) of 5.25m2 or more are considerable as a device space for individual use. Existing oxygen capsules are not only functional but also economical and practical in that they can be said to be wasteful.
