Description

{EMERGENCY BREATHING APPARATUS}

The present invention relates to an emergency breathing apparatus, and more particularly, to an emergency breathing apparatus that improves portability through implementation of light weight and compactness, and enables breathing for a certain period of time in a space filled with toxic gas.

One of the biggest deaths or injuries in the event of a fire is a variety of toxic gases that are caused by a fire, and even if the toxic gas is inhaled several times, it may lose consciousness and lead to death without escaping from the place where the fire occurred .

Generally, a fire is often generated from the interior of a building, and the time required to escape from the fire scene is approximately 2 to 5 minutes.

In view of the above, the present invention was invented so as to escape while normally breathing from a fire scene, as disclosed in Korean Patent Laid-open Publication No. 10-2004-0084195, "Emergency oxygen re- , "Emergency Oxygen Safety Mask" of Japanese Patent Application Laid-Open No. 10-2008-0047523, and "Portable Self-Oxygen Breathing Apparatus and Mask with it" of Japanese Patent Application No. 10-1047082.

The above-described prior arts are provided in the form of a respiratory apparatus with a respirator or an oxygen tank. Such apparatuses may be able to escape from a fire scene while breathing normally. However, the problem is that the above- There is a problem in that the load and the size are large.

To solve these problems, an escape oxygen respirator (hereinafter, referred to as 'oxygen respirator 1') has been developed and marketed.

The above-described oxygen respirator 1 is equipped with an oxygen can in a hood made of flame retardant fabric that can withstand 150 degrees Celsius, and can supply 10 L of compressed oxygen for 5-10 minutes by manually manipulating the valve from time to time.

However, since the oxygen respirator 1 described above is about 170 g as a whole, its volume is more than 500 cc, so it is still a burden to carry around. The oxygen respirator 1 is equipped with a compressed oxygen tank (oxygen volume 10 L) in a vinyl hood, To keep the oxygen concentration inside the plastic hood.

Since the oxygen respirator 1 is used at a level of about 5 minutes with 10 L of oxygen, there is a problem that oxygen is wasted and one hand is not free because of valve operation.

In addition, Air Supply ™ EEBD M-15 ('Oxygen Respirator 2') has been developed and marketed.

In the oxygen respirator 2 described above, 18L of oxygen compressed in the aluminum can is filled in the oxygen bag at the moment when the lever is operated, and the air through the mouthpiece passes through the adsorbent and is filtered by the carbon dioxide.

For reference, 21% oxygen, nitrogen and other substances are inhaled at the time of inhalation and 17% oxygen, 4% carbon dioxide, nitrogen and other substances are released at the time of exhalation.

That is, the oxygen respirator 2 is structured to filter 4% of carbon dioxide by the carbon dioxide adsorbent at the time of exhalation and recycle the remaining oxygen of 17%, and it is operated by using 18 L of oxygen for 15 minutes or longer. So as to minimize the waste of oxygen by keeping the concentration of oxygen high.

However, this oxygen respirator 2 is very heavy due to the adsorbent, so it is difficult to carry normally.

In short, in the case of the oxygen respirator 1, since the hood is used, there is a great problem of waste of oxygen.

Accordingly, the oxygen respirator 1 requires a large oxygen tank to allow normal respiration for a certain period of time, and since it has to use a hood, the oxygen respirator 1 has a problem in that it has a weight of about 170 g and a bulky size.

In addition, since the oxygen respirator 2 has a weight or volume of about 800 g or more because it needs a carbon dioxide adsorbent, the oxygen respirator 1 is too large in weight or volume to be carried at all times.

In particular, the above-mentioned prior arts including the oxygen respirators 1 and 2 are one of the obstacles to popularization because there are many expensive products.

On the other hand, the general person breathes about 20 times per minute, and the respiratory air volume per one is about 500cc. Among them, oxygen is 21%, that is, about 100cc. Consumed and 4% of carbon dioxide is generated.

Therefore, the amount of oxygen required for a person to breathe for 1 minute is 20 x 20 = 400 cc. For example, 1.2 L of oxygen is needed to breathe for 3 minutes.

However, when the oxygen concentration is below 12 ~ 15%, breathing becomes difficult. Especially in an emergency such as a fire, the consumption of oxygen increases rapidly as the person breathes more than two or three times faster.

In the case of the 3L oxygen bag, for example, assuming that the oxygen concentration is 15% or less (3L x 0.15 = 450 cc), 450 cc of oxygen is inefficiently discarded, so if the abandoned oxygen can make the most of oxygen, It will be possible.

Therefore, it is urgent to develop a device capable of storing and carrying it in a usual pocket or a handbag, and allowing normal breathing for a predetermined time or longer even in a place where a large amount of toxic gas such as a fire scene occurs.

2 to 5, the oxygen tank 40 shown in FIG. 1 is omitted for the sake of understanding of the drawings.

The emergency breathing apparatus 1 according to an embodiment of the present invention includes a space 11 connected to a mouth of a user as shown in FIG. 1, and includes oxygen gas (hereinafter referred to as O2) and carbon dioxide And the respiration bag 10 separating O 2 and CO 2 by the density difference and the diffusion speed difference of the gas (hereinafter referred to as "CO 2").

Accordingly, the present invention can increase the convenience of carrying through the implementation of a lightweight and compact structure, and enable breathing for a certain period of time in a space filled with toxic gas.

The present invention can be applied to the embodiments described above, and it goes without saying that the following various embodiments can be applied.

1, the emergency respiratory apparatus 1 includes a mouthpiece 20 which can be breathed by a user and a mouthpiece 20 connected to the end of the mouthpiece 20 to communicate with the space 11, And may be further provided with a first check valve 31 which is opened only at the time of user's inhalation.

Here, when the user exhales, the exhaust gas such as carbon dioxide is discharged from the user's body through the exhaust port 35, which is disposed adjacent to the first check valve 31 and communicates with the dental mouthpiece 20, into the space 11 .

2, the emergency breathing apparatus 1 includes a mouthpiece 20 and a first check valve 31. The emergency breathing apparatus 1 is connected to the end of the dental mouthpiece 20, And the second check valve 32, which is opened only when the user exhales.

Here, the first check valve 31 and the second check valve 32 may be embedded in the respiratory bag 10.

The emergency breathing apparatus 1 may further include a discharge pipe 33 connected to an end of the second check valve 32 to form an internal flow path extending to the vicinity of the bottom surface of the breathing bag 10.

The discharge pipe 33 is made of a thin and flexible material such as the breathing bag 10.

In this case, the exhalation, including O2 and CO2, moves from the lower part of the respiration bag to the upper part, where O2 with a smaller density tends to stay above the dense CO2.

In addition, O2 with a lower molecular weight than CO2 is moved to the top by Graham's law (Graham's law) faster than CO2 with higher molecular weight.

Therefore, since the upper part of the space 11 always has a higher O2 concentration than the lower part, the inflow into the first check valve 31 located at the upper part makes use of available O2 to the maximum, so that the waste of O2 can be minimized .

Since the oxygen respirator 2 described above increases the concentration of O 2 by a chemical method of adsorbing CO 2, an apparatus such as an adsorbent is additionally required. In the present invention, O 2 consumption is minimized by a physical method using difference in density of CO 2 and O 2 and difference in diffusion rate So that it is possible to maximize the resting comfort by reducing the weight and volume by eliminating the need for an additional device such as an adsorbent.

The breathing bag 10, the mouthpiece 20, the first check valve 31 and the second check valve 32 are made of a flame retardant material or a heat resistant material having flame retardancy and heat resistance, .

On the other hand, the respiratory bag 10 can be made longer in length than the transverse length to help facilitate the separation of O 2 and CO 2 according to the density difference of O 2 and CO 2 and the Graham's jetting / diffusion law .

Here, the breathing bag 10 is folded into several folds at the time of manufacture to minimize the volume and then be assembled and produced.

The structure of the respiratory bag 10 will be described in more detail with an upper end edge 12 having a first length L1 to which the mouthpiece 20 is connected and an upper end edge 12 having a first length L1 And having a second length L2 longer than the first length L1 and connecting both ends of the upper end edge 12 and both ends of the lower end edge 13 and having opposite side edges 14a, 14b.

The space 11 is formed by the upper end edge 12, the lower end edge 13 and the side edges 14a and 14b to accommodate O2 and CO2 due to the user's inhalation and exhalation.

In this case, the ratio of the first length L1 to the second length L2 can be freely modified within a range of 1: 5 to 10 so that the mutual separation of O2 and CO2 according to the density difference of O2 and CO2 can be more easily performed. have.

The present applicant has developed a respiratory bag 10 having a first length L1 of 12 cm and a second length L2 of 80 cm and using 4 liters of oxygen to fill the bag. As a result, Minute breathing was possible.

1, the emergency breathing apparatus 1 is connected to the mouthpiece 20 to supply a user with a high concentration of O2 to allow normal breathing of the user, 11 to supply O2 to the reaction chamber.

Here, it is preferable that the oxygen tank 40 is provided in a structure that is detachably coupled to the dental mouthpiece 20 for replacement or inspection.

At this time, O2 contained in the oxygen tank 40 may be oxygen or liquid oxygen compressed to about 200 atm.

Needless to say, the emergency respiratory apparatus 1 may further include a third check valve 41 for communicating the respiratory bag 10 and the oxygen tank 40 with each other.

4, the flow of the gas is the same as the direction of the dotted arrow, and the first check valve 31 opens the flow path so as to communicate with the space 11.

5, the flow of the gas is the same as the one-dot chain line arrow direction, the second check valve 32 opens the flow path so as to communicate with the space 11, and the discharged gas flows through the discharge pipe 33 And the CO2 and O2 contained in the discharged gas are shifted to the lower part by the density difference and the O2 which is relatively lighter than the CO2 to the upper part.

5, O2, which is included in the exhausted gas and moved to the upper side of the space 11, is recycled to the user's respiration through the first check valve 31, .

As described above, the emergency respiratory apparatus 1 according to various embodiments of the present invention is made of a material that is flexible and has excellent flame retardancy and heat resistance, The bag 10 is folded or rolled into a storage box 50 having a separate first storage space 51 so as to maximize the convenience of carrying it at all times as shown in FIG. 6, and the oxygen tank 40 ) Into the second storage space 52 of the storage box 50 and put them in a bag or a handbag (not shown).

Therefore, the user quickly removes the respiratory bag 10 and the oxygen tank 40 from the receptacle 50 in a situation where normal breathing is difficult, such as a fire, and connects the oxygen tank 40 to the mouthpiece 20 to inject oxygen The user will be able to safely escape from the scene of a fire or emergency while breathing mouthpiece 20 with mouth only.

As described above, it is understood that the present invention is based on a technical idea to provide an emergency breathing apparatus which improves the convenience of carrying through the implementation of light weight and compactness and enables breathing for a certain period of time in a space filled with toxic gas .
