Abstract

The present invention relates to a rescue mask for fire evacuation, comprising a filling pack having storage chambers on the left and right sides for filling oxygen in a compressed state, with a coupling hole perforated in the sealing piece of the storage chamber; an air exhauster connected to the filling pack to discharge internal oxygen to the outside; and a mask part having an adsorption sheet fused to the front and back of the filling pack to adsorb a blocking liquid, thereby allowing anyone to use it easily and conveniently to safely and quickly escape from a dangerous area caused by fire. In the event of a fire, the user can evacuate immediately, and in the event of the occurrence of toxic gases, the circular pressure port of the control block is adjusted to smoothly supply oxygen to the breathing part on the inner surface of the rescue mask, thereby blocking toxic gases in the dangerous area and providing high-quality oxygen to enable a quick and safe escape. At the same time, if the evacuation time is extended, the medical pocket is opened with a cut strap so that the oxygen generating substance contained inside reacts to generate oxygen, thereby stably extending the oxygen supply time to the dangerous area and inducing safe evacuation.

Description

fire-evacuation rescue mask The present invention relates to a fire evacuation rescue mask, and more specifically, to a fire evacuation rescue mask that stores compressed air inside the mask to supply oxygen for a predetermined period of time in case of an emergency such as a fire, thereby enabling safe and rapid evacuation from a dangerous area. Recently, a large amount of building materials made of various chemicals are being used in buildings and interiors. As the size and number of buildings are growing larger and increasing rapidly, the number of casualties in the event of a fire is also rising. As industrial society continues to advance, recent high-rise buildings consist not only of offices but also various shops, restaurants, and shopping centers, with internal foot traffic reaching thousands; consequently, the risk of fire is expected to increase even further. Moreover, when a fire occurs, a large amount of combustion gases are generated, and these released gases are often toxic. Most chemical substances contained in building materials or clothing are generally composed of elements such as nitrogen, sulfur, and halogens, with carbon, hydrogen, and oxygen as the main components. In the case of complete combustion, where chemical substances burn to produce only carbon dioxide and water, no combustion products are generated; however, in reality, complete combustion of chemical substances rarely occurs during a fire. Generally, when chemicals burn, incomplete combustion occurs, generating other gases such as carbon monoxide, ammonia, and nitrogen dioxide in addition to carbon dioxide and water. In this case, a large amount of oxides and decomposition products are produced, and these decomposition products are toxic and affect the human body. According to statistics from the National Fire Agency, suffocation by gas and smoke accounts for more than 60% of deaths when a fire occurs in a building or facility. High toxicity is generated due to oxygen deficiency and the mixing and synergistic effects of toxic gases. Furthermore, as evacuees panic during a fire, their breathing volume increases three times more than usual, leading to the inhalation of large amounts of toxic gases. For example, when the oxygen concentration decreases and incomplete combustion occurs, a large amount of carbon monoxide is produced as a combustion product, regardless of the type of chemical or material. Even in extremely small amounts, carbon monoxide has fatal toxic effects on the human body, and about 20 minutes after a fire starts, it accounts for more than 5% of the air composition. When carbon monoxide is inhaled into the body, it inhibits the activity of hemoglobin, which carries oxygen in the blood, thereby impairing central nervous function and causing loss of consciousness, which can lead to death. In addition, combustion gases generated during a fire contain various types of toxic gases, and toxic gas components include ammonia, hydrogen chloride, nitrogen phosphate, sulfur dioxide, chlorine, hydrogen cyanide, and phosgene. In addition, during a fire, the oxygen in the air rapidly decreases due to the combustion of materials, and a lack of oxygen can lead to fatal accidents. Furthermore, the generation of large amounts of smoke obstructs visibility, making evacuation difficult. Therefore, rapid evacuation is essential in the event of a fire, and it must be carried out with the mouth and nose covered to prevent the inhalation of toxic gases. Covering the respiratory tract with a handkerchief, wet towel, or sleeve is the most common method of evacuation, but this does not effectively block toxic gases, and there may be difficulties in evacuation because there is a lack of oxygen and one hand is not free while holding the handkerchief or similar item. Meanwhile, although gas masks are provided to prevent the inhalation of toxic gases, the masks currently available on the market are difficult for the general public to wear as they have never encountered them in daily life; furthermore, they are bulky and heavy, making storage and portability very inconvenient, and their high cost poses challenges in management and supply. In addition, gas masks filter smoke through a filter attached to the outside, but harmful gases rapidly contaminate the filter, causing it to lose its function, or when a large amount of smoke is generated, the filter becomes clogged after only one or two breaths, making normal breathing difficult and leading to an emergency situation where oxygen is insufficient, which poses a risk of death by suffocation. Accordingly, oxygen-generating masks utilizing compressed oxygen are being proposed; however, the large volume of the oxygen tank required to store the compressed oxygen reduces wearability and portability, and since the amount of oxygen that can be supplied is limited, the usage time is short, making it unsuitable for use when evacuation time is delayed. In addition, when breathing high-purity oxygen,
