Description

Portable self respiration device of Oxygen and mask having the same}

The present invention relates to a portable self-oxygen breathing apparatus, and more particularly, a user equipped with a oxygen generator, which is a solid product manufactured by compressing and processing a powder containing a mixture of manganese oxides such as KO ₂ and manganese oxide and manganese dioxide, in a purifying container. Portable self-oxygen breathing apparatus for preventing asphyxiation from toxic gas by supplying to user by changing oxygen breathing to oxygen in case of emergency due to fire by simply keeping it inside subway, train, underpass or building It is about a mask.

Generally, portable oxygen generators are currently used very usefully in various fields. For example, in a fire scene, air pollutants may be included or harmful substances may be harmful to the human respiratory system. In emergency situations where air is contaminated beyond breathing, portable oxygen supplies are useful for preventing people from choking while waiting for medical rescue. In other treatment or medical applications, the oxygen supply can be used to It may also be used as an auxiliary oxygen source to assist in providing a sufficient amount of oxygen to the blood.

Oxygen supply devices are also used as a supplementary oxygen source in the therapeutic or medical field, helping the lungs to get enough oxygen to reach the blood.

For example, a conventional oxygen supply device used by firefighters has an oxygen tank or cylinder for storing oxygen under pressure. In order to access oxygen contained in the tank, the user opens a valve connected to the gas output of the oxygen tank, Oxygen can breathe through a breathing mask connected to an oxygen tank.

However, since the oxygen tank stores oxygen under pressure, a case is usually made of metal, and thus, a dangerous situation may occur when inadvertently dropped on the ground. In addition, the contents of the tank will be vaporized, so it is necessary to inspect it regularly, and care must be taken because it requires filling from a service technician.

On the other hand, coal miners are working with only a dust mask, unlike firefighters. If the tunnel collapses, the entrance of the tunnel is blocked and oxygen is rapidly reduced, which can cause fatal consequences for human life. . In anticipation of such a collapse, an oxygen supply device (including a mask) is provided in the middle of the tunnel, but this is also very heavy and not easy to use.

As described above, the present invention can easily prevent asphyxia by suffocating by automatically supplying oxygen from toxic gas for several minutes in case of emergency due to fire by easily carrying it by user or carrying it inside subway, train, underpass or building. It is a very useful invention.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

The present invention prevents choking by automatically supplying oxygen from the toxic gas for a few minutes (for example, 15 to 60 minutes) in case of an emergency caused by a fire by carrying the user easily or conveniently stored inside the subway, train, underpass or building. To this end, the self-breathing apparatus 1 according to an embodiment of the present invention for this includes a main housing 10.

The main housing 10 is closed at one end to maintain the strength that does not shrink when a person breathes, the other end includes a cylindrical casing (11) formed with a female thread (11a), this Inside the casing 11, a tube member 12 formed perpendicular to the casing 11 is fixed. A plurality of openings 12a are formed in the tube member 12, and the lower side of the casing 11 is formed. The side, that is, the lower protrusion of the tubular member 12 is sealed with the outside when a person breathes, so that the oxygen generated in the oxygen generator 20 is exhaled from the user's lungs as described later and supplied to the lungs again. The shaped container 13 is fixed.

Here, the bag-shaped container 13 is preferably made of a material that can expand and contract when a person breathes easily.

On the other hand, the oxygen generator 20 is inserted into the casing 11, the oxygen generator 20 is 90 to 99: 10 to 1% by weight of the manganese oxide, such as KO ₂ and manganese oxide or manganese dioxide The solids produced by compression-processing the powder mixed with the resin are preferable. The solids are compressed by a tablet press, press, or the like, and processed into tubular, tablet or flake shapes having a thickness of about 2 mm and placed in a predetermined bag to be housed in the casing 11. It is desirable to.

When the oxygen generating agent 20 is accommodated in the casing 11, one end of the casing 11, ie, the portion of the female screw 11a, needs to be sealed. For this purpose, the outside air is used by using the sealing member 30. Must be blocked.

Because when used as a self-contained oxygen generator alone with 100% potassium acetate (KO ₂ ), it becomes difficult to induce a chemical reaction close to 100% irrespective of the shape. In the present invention, oxygen is used as the inorganic catalyst. By using manganese dioxide (MnO ₂ ), which is known to generate, as a catalyst, the chemical reaction of KO ₂ can be facilitated, and the chemical reaction can be improved to about 90%.

Therefore, in case of fire or the like, the sealing member 30 is removed as shown in FIG. 2, and then the male screw 51 of the air purifying container 50 is screwed into the female screw 11a of the casing 11, and then the face portion 41 made of rubber material. After wearing the face protector (40) having a user's face is used to tie the back of the face as a binding strap (42).

Therefore, when the user breathes, the carbon dioxide (CO ₂ ) and moisture (H ₂ O) emitted by the user will react with KO ₂ as shown in the following formula.

2 EN ₂ + CO ₂ ---> EN ₂ CO ₃ + 2 / 3O ₂

2 EN ₂ + H ₂ O ---> 2KOH + 2 / 3O ₂

KO ₂ hitting the theoretical amount of pure oxygen that can be caused by the chemical reaction is 234cc / g. When 60 g of KO ₂ causes 100% chemical reaction, it is 234 × 60g = 14,040 cc (about 14L), but the oxygen concentration in general air is about 20% and can absorb 14L × 5 = 70L of air. Will be. However, in the reaction of KO ₂ alone, it is less than 50% of the theory because it is difficult to cause 100% of the reaction with only water and carbon dioxide emitted by humans. That is, it has only an air supply capacity of less than 35L (for this reason, it is preferable to maintain the oxygen supply amount by using a KO ₂ amount that is more than twice the theoretical value in the actual product).

In the present invention, by improving the chemical reaction level to 90% or more, the use of a small amount of KO ₂ (reduces the weight and size of the product) of the conventional KO ₂ sole oxygen generator is made practical.

The portable self-respiratory apparatus 1 of the present invention is worn as shown in FIG. 3 and FIG. 4 at a fire site to breathe as shown by a dashed line. In the first use, the bag-shaped container 13 is expanded to some extent. It is preferable to use after making it possible. Therefore, after removing the sealing member 30 as described with reference to FIGS. 1 and 2, the main housing 10 and the face protector 40 are quickly screwed and used to self-breath the oxygen deficiency caused by fire. It can be prevented.

Figure 5 shows another embodiment of the coupling method of the main housing and the face protector of the present invention bar shown in Figure 4 but the screw coupling method shown in Figure 5 is a method using a rubber ring 60 Since it is the same except for the detailed description of other components will be omitted. In FIG. 5, other parts are attached with numerals in units of "100".

As can be seen in FIG. 5, a recess 111a is formed in the casing 111, and a recess 151 is formed in the outer circumference of the air purifying barrel 150, and a rubber ring 60 is formed in the recess 151. When the main housing 100 is connected by removing the sealing member 30, the casing 111 of the main housing 100 is inserted into the outer circumference of the air purifying cylinder 150 by the rubber ring 60. Outside air will not be introduced into the bag-shaped container 13 or the user's lungs.

6 to 8 illustrate a self-breathing apparatus 100 according to another embodiment of the present invention, which further includes a plurality of unit housings 200 each containing an oxygen generating agent 20. Bars 200 are sequentially connected to the main housing 10 to extend the generation time of oxygen, the unit housing 200 has a first end with a female screw 211a and a second end with a male screw ( Cylindrical casing 211 provided with 211b), sealing members 30 for sealing the first and second ends, respectively, and housed in the cylindrical casing 211 and air in case of breakage of the sealing members 30; An oxygen generator 20 for generating oxygen in contact; And caps 220 respectively coupled to the first and second ends of the cylindrical casing 211 to prevent breakage of the sealing members 30.
The cap 220 has a female screw 220a formed on an inner circumferential surface of the opening.

Therefore, even when one oxygen generator 20 is used, the user may extend the emergency breathing by connecting another unit housing 200 when there is no touch of the structure.
In the figure, reference numeral 52, 152 is a filter provided in the air purifier 150.

9 and 10 show another embodiment in which the self-breathing apparatus 300 according to the present invention is mounted on a conventional mask 310 having a light transmitting lens 312 and a face protector 311. As described above that can be interconnected by a screw coupling or rubber ring coupling method, a detailed description of the generation of oxygen will be omitted.

As described above, the present invention is equipped with an oxygen generator which is a solid product manufactured by compressing and processing powder mixed with manganese oxide such as KO ₂ and manganese oxide and manganese dioxide in a purifying tank, and carried by a user or inside a subway, train, underpass or building. In case of emergency by fire, it is possible to prevent the suffocation from toxic gas by supplying to the user by converting the breath discharged by oxygen into oxygen.

Although the present invention has been described with reference to the accompanying drawings, the present invention is not limited thereto and there may be many variations and modifications within the scope of the following claims.

For example, instead of attaching a sealing member to prevent accidental operation of oxygen generators in general, the present invention may be folded and accommodated in a separate plastic pack so as to be quickly operated when the plastic pack is opened or inserted into a separate can container. It can also be activated when the canister is opened.

In addition, the sealing member 30 is attached to the inside of the face protector 40 or the mask 310 in a state in which the main housing 10 and the face protector 40 or the mask 310 are connected to each other so as to be operated by removing them. Of course you can.
