Description

  The present invention relates to an ultra-small portable simple air mask for disaster prevention.

Gas poisoning and oxygen deficiency incidents due to fires in closed spaces such as buildings, underground malls, tunnels, etc., gas such as carbon monoxide due to explosions, volcanic gases such as hydrogen sulfide, sulfurous acid gas, etc. frequently occur There are many deaths every year, and there are many people who suffer from sequelae, with several times more addicted patients, and for example, the return of the direct Kanto earthquake and the Great Tokai earthquake, Although it is said that the situation is not strange at any time, development efforts of disaster prevention tools to cope with these disasters have been made eagerly, but practical use of products especially for toxic gas, oxygen deficiency and harmful dust There is the present situation that the conversion is remarkably delayed. The main reason for this is that although patents of these corresponding technologies are disclosed, all have advantages and disadvantages, and the chances of encountering these incidents are extremely small for individual people. . In other words, in order to cope with an unexpected encounter when it does not occur, it is necessary to always keep the disaster prevention equipment aside, but the next reason is the lack of portability, etc. This is probably due to the lack of excellent products. For example, Patent Document 1 proposes a full-scale disaster prevention rucksack that covers a rucksack in the event of a disaster and copes with toxic gas with a small oxygen cylinder built in the rucksack. In this case, various disaster prevention goods are put in the backpack, and it can be used as an air mask if necessary. When evacuating when an earthquake occurs, carry the backpack stored in the room in advance. It's great for escaping, but it's too big to fit at all times. Patent Document 2 proposes a helmet integrated with a disaster prevention suit as shown in FIG. 1, and the head is placed inside a full-face helmet 1 made of a transparent material such as polycarbonate covering the foldable head in FIG. The protective mask 2 is provided, and a flame mask 3 is attached to the lower part of the helmet 1, which is tightened at the neck by a fit belt 4 to block outside air, and the gas mask 5 removes toxic gas. The disaster prevention suit integrated helmet uses a foldable helmet, and other parts can be folded in a small size to make it more convenient to carry. Because it is a hard transparent resin molded product, it is inevitable that it is bulky even after folding, and it is too large to always carry, Because the lumet part is foldable, airtightness is likely to be insufficient during use, and there is a high risk of toxic gases entering inside, and because it is a method of removing toxic gases with a gas mask, There was a big problem in practicality, such as being completely powerless and lacking an effective gas mask for all toxic gases, depending on the type of toxic gas.

  The present invention relates to a poisoning or oxygen deficiency incident caused by a toxic gas such as a carbon monoxide, hydrogen chloride, chlorine, or an organic solvent caused by a fire or explosion in a closed space such as a building, underground mall, or tunnel, etc., hydrogen sulfide gas, sulfurous acid It is inconvenient to carry and not practical at all in disaster prevention equipment for any respiratory disaster such as gas poisoning due to volcanic gas such as gas, oxygen deficiency, or asbestos, radioactive particles and other harmful dust leaks. The problem is to fundamentally solve major problems such as lack of oxygen and ineffective depending on the type of toxic gas.

  In order to solve the above-mentioned problems, in the present invention, the user can secure visual acuity, can be folded small, covers a non-breathable bag on the head, and then lightly closes the neck with a belt etc. The bag was covered with a bag, and oxygen or oxygen-rich air or air was supplied in small amounts through a soft tube or the like with a portable small cylinder.

  According to the method of the present invention, since a bag is used, it can be folded very small, and at the same time, by using a portable small cylinder, it can be stored much smaller than before and the portability is remarkably improved. It is extremely easy to carry in a corner of a bag or the like at all times, and because it uses an air mask system that introduces oxygen or oxygen-rich air into the bag little by little, it is possible to use all toxic gases or oxygen deficiency or Evacuation for a long time such as a fire in a tunnel because it is effective for all respiratory system disasters such as leakage of toxic particles, and life can be maintained for a long time by introducing small amounts from small cylinders. Sufficient time can be secured, and a transparent material is used for part or all of the bag, and if necessary, the anti-fogging function is added to ensure vision during evacuation. To protect the precious life brings a great deal of effect, such as it is easy.

  FIG. 2 shows a side view of an embodiment of a simple air mask according to the present invention. A victim A who encounters a toxic gas such as a fire or explosion accident, an oxygen deficiency incident, etc., immediately folds into a small corner of the bag in advance. The air inflow pipe which is sealed and attached to the bag 6 with the belt 6 or rubber ring lightly tightened with a belt 7 or rubber ring that can be fixed with one touch such as opening the bag 6 stored on the head and covering the head with a hook-and-loop fastener. 8 and a small cylinder 9 are connected by a heat-resistant deformable silicon rubber, plastic, metal tube 10 and the victim A operates the small cylinder 9 such as oxygen-rich air by hand. By letting it flow into the bag 6, it is possible to secure a sufficient time necessary for evacuation and protect the life.

  The bag 6 used in the present invention needs to be foldable, transparent and secure visual acuity, and preferably resistant to high heat such as a fire, but such an ideal one is hardly present on the market. However, for example, a thin heat-resistant material that maintains airtightness by impregnating a heat-resistant resin such as silicone into a cloth using a heat-resistant fiber such as stainless steel or carbon fiber such as rock wool or glass fiber as shown in FIG. A window portion 11 made of a transparent heat-resistant material that secures visibility on the cloth, or the whole is made of transparent plastic, and is relatively superior in terms of tear strength and heat resistance, such as polyester, stretched polyamide, etc. The bag 6 using the transparent plastic may be used. In the embodiment in which the window portion 11 made of a transparent heat resistant material is bonded to the heat resistant cloth, the window portion 11 is transparent, soft, excellent in heat resistance to withstand high temperatures such as fire, and can be folded. However, since such a material cannot be expected at present, a small window made of a hard material such as infrared cut heat-resistant transparent glass is attached to this part, and it is folded so that this window part is rolled up. The enabling method is also within the scope of the present invention. By adopting this method, the head can be protected from heat such as a fire, and a full-scale air mask with a long life-span effect can be obtained. Also, in order to prevent eyesight during evacuation, an antistatic agent using a surfactant is applied or kneaded into the transparent plastic part to be used to prevent fogging inside the bag due to moisture from exhaled air. It is desirable to use an anti-fogging treatment.

  As the contents of the small cylinder 9 used in the present invention, compressed oxygen gas, or oxygen-enriched air or air filled air can be used. From the viewpoint of safety and life extension time, oxygen gas 60%, nitrogen gas It is desirable to use about 40% oxygen-rich air. For example, by adopting a 50 cc and 60 atm cylinder for 60% oxygen gas, 10 liters of gas can be supplied at normal pressure. A sufficient life extension time can be expected, and if a cylinder of pure oxygen gas is used, a longer life extension effect can be obtained.

In the above-described embodiment, a configuration in which the air inflow pipe 8 is bonded and fixed to the bag 6 is adopted. However, the air inflow pipe 8 is closed with a small cylinder 9 not connected to the outside air. It is desirable to provide a check valve that does not enter the inside and opens when the cylinder is press-fitted, and the bag 6 is not provided with the air inflow pipe 8, and the soft pipe 10 is placed inside the bag 6 as shown in FIG. A method may be used in which air is introduced from a small cylinder 9 by lightly tightening with a belt 7 after insertion. In this case, a female and a male such as a hook-and-loop fastener 12 are respectively provided inside the bag 6 and outside the tube 10. Is attached at an appropriate position, and the male and female are crimped according to the position, so that it is possible to prevent the soft tube from coming off at the time of use, and in any case, depending on the size of the bag. From a cylinder for a short time of a few minutes It is not necessary to supply the original it is possible to prolong life. In the present invention, a method in which oxygen is directly blown into the bag without using the tube 10 is also within the scope of the present invention.

It is a side view of the simple gas poisoning apparatus in the conventional method. It is a side view of the use condition which the disaster victim equipped with the portable simple air mask which adhered and provided the air inflow tube in the bag in this invention. It is a front view at the time of adhering and providing the transparent window part 11 of the heat resistant material which ensures visibility to the thin heat resistant cloth in this invention. It is a side view of the use condition which the disaster victim equipped with the portable simple air mask at the time of inserting a soft pipe | tube directly in the bag in this invention.
