Description

Oxygen mask {OXYGEN MASK}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an oxygen mask for preventing asphyxia in a situation where a user is exposed to a toxic gas, and more particularly, to an oxygen mask capable of minimizing size and weight while extending the use time.

A gas mask is a typical safety device used in a situation where a user is exposed to a toxic gas such as a fire. However, since the respiratory mask simply cleanses the toxic gas of the outside air and allows the user to breathe, it becomes completely useless in the oxygen-deficient space. Therefore, there is a need for a safety mechanism that can solve the problem more fundamentally.

To meet this need, oxygen masks have been developed. Conventional oxygen masks supply oxygen continuously to breathe fresh air into the hoods and hoods surrounding the user's head to block the ingestion of toxic gases And an oxygen container.

However, in the conventional oxygen mask constructed as described above, there is a problem that the size and weight of the oxygen container are large and the coupling structure of the hood and the oxygen container is complicated, and portability and simplicity are very low.

Particularly, in a situation where a user is exposed to a toxic gas, the oxygen mask must be quickly worn and must be safely evacuated while considering the surrounding environment. Therefore, the problem of the conventional oxygen mask related to portability and simplicity must be solved will be.

However, if the capacity of the oxygen container is simply reduced in order to minimize the size and weight of the oxygen mask, the amount of oxygen stored in the oxygen container is reduced, so that a new problem that the use time is shortened may occur.

A new problem in that the use time is shortened is that, due to the structure of the hood included in the conventional oxygen mask, it is difficult to handle the carbon dioxide or moisture contained in the air discharged by the user during breathing, The time limitation may lead to a problem that the user can not flexibly cope with the surrounding situation.

That is, according to the conventional oxygen mask, when the capacity of the oxygen container is reduced in order to maximize the portability and simplicity, the use time is shortened so that it can not be flexibly coped with the surrounding situation. In order to increase the use time, There is a problem that portability and simplicity can not be maximized.

The respiratory bag 100 may be made of any material that can prevent air from flowing between the outside and the inside of the respiratory bag 100, and thus the scope of the right is not limited.

For example, the material of the respiratory sac 100 may be a flexible synthetic resin material such as vinyl or rubber for easy folding and storage when not in use, It may be made of the same hard synthetic resin material as plastic. In addition, the respiratory sac 100 may be formed of a flame-retardant reflective material so as to protect the face from a flame and inform the user of the position of the user.

The opening 110 is formed at one side of the breathing receptacle 100, which may be made of various materials, such that the user wears or removes the breathing receptacle 100. The user may wear the respiratory bag 100 by inserting his or her head into the respiratory bag 100 through the opening 110 or remove the head from the respiratory bag 100 through the opening 110 after use, ).

In order to prevent external air from entering the inside of the respiratory bag 100 through the opening 110 after the wearer wears the respiratory bag 100 by inserting a head into the opening 110, .

The throttling portion 111 is provided along the opening 110 so that it can be closely attached to one side of the neck or head of the user so that air flowing inside and outside the breathing portion 100 flows by tightening one side of neck, Or to minimize the flow of air.

The throttle unit 111 may be of any type as long as it can tighten the opening 110 to prevent the flow of air. However, the throttle unit 111 may be formed of an elastic band or a cord provided along the opening 110 It will be more advantageous in view of convenience.

In addition, a viewing window 120 may be provided on one side of the respiratory bag 100 so that the user can visually confirm the external situation easily.

If the material of the respiratory sac 100 is transparent, a separate window 120 is not required. However, if the material of the respiratory sac 100 is not a transparent material, The viewing window 120 should be provided so that the user can visually confirm the situation of the user.

The transparent window 120 may be formed of any transparent material such as transparent vinyl, acrylic, polycarbonate or the like so that the user wearing the hood can easily recognize the external situation.

However, it is advantageous that the viewing window 120 is formed to have a double-sided structure in order to prevent sex offense due to a temperature difference between the inside and the outside of the respiratory bag 100.

Meanwhile, the respiratory unit 200 is provided inside the respiratory bag 100 to enclose the respiratory apparatus such as the user's mouth or nose, or to be inserted into the respiratory apparatus to easily induce the respiration of the user.

The respiratory part 200 may be formed to surround the respiratory part of the user or may be formed to be inserted into the inside of the respirator such as a mouth piece or a nose piece, And, of course, the scope of the rights is not limited thereby.

However, for the sake of more detailed description, as shown in the drawings, an embodiment of the present invention will be described with reference to a form including a face portion 210 which is closely attached to the nose or mouth of a user and surrounds the respiratory apparatus .

That is, the respiratory unit 200 in the embodiment of the oxygen mask according to the present invention may include the face unit 210 and the connection unit 220.

At this time, the face portion 210 is formed to surround at least one of the user's mouth and nose and is formed to closely contact the user's face of the respirator. The face portion 210 may be formed in various forms in consideration of the facial skeleton of the user Of course.

In addition, the face portion 210 may be formed of a soft material having a light and elastic restoring force. When the face portion 210 is formed of a soft material having an elastic restoring force, the adhesion force of the face portion 210 is improved, and the folding can be performed as needed.

An opening hole may be formed at one side of the face portion 210 so that the face portion 210 can be connected to the connection portion 220. A head string connection portion 211 may be further formed at a rim portion of the face portion 210. [

Here, the hair-cord connecting portion 211 is a component to which a head strap (not shown) is connected. When the user wears the oxygen mask 10, the hair- To be adhered or fixed.

At this time, the material and shape of the head strap are not limited. However, it is advantageous that the head strap is formed in a ring shape as a predetermined elastic material such as an elastic band so that the user can quickly wear the face portion 210.

The connecting portion 220 is provided to be coupled to an opening formed at one side of the face portion 210 to introduce air inside the face portion 210 into the face portion 210 to induce air to be easily sucked by the user. Lt; / RTI >

One end of the connecting portion 220 is coupled to the opening of the face portion 210 and the other end of the connecting portion 220 is coupled to one side of the respiratory bag 100. The air inside the respiratory bag 100 flows into one side of the side portion of the connecting portion 220 Through holes 221 are provided so as to provide a passage through which the fluid can pass.

One end of the connection portion 220 coupled with one side of the respiratory sac 100 may be closed to be exposed to the outside of the respiratory sac 100 and oxygen may be introduced into one side of the connection portion 220 into the inside of the respiratory bag 100 An oxygen supply unit 400 may be formed.

At this time, the connection part between the respiratory bag 100 and the connection part 220 can be sealed so that no external air flows. The oxygen inflow part 400 includes a connection part 220 to be coupled with one side of the respiratory bag 100, And a coupling protrusion that penetrates through one side of the respiratory bag 100 and can protrude outside the respiratory bag 100 and into which a flow path 410 for connecting with a separate oxygen supply means can be inserted.

Of course, it is needless to say that the oxygen supply unit 400 need not necessarily include the coupling protrusion at one side of the connection unit 220 as described above, and thus the scope of the right is not limited.

That is, the oxygen supply unit 400 includes various components connected to at least one of the respiratory bag 100 or the filter unit 300 to be supplied with oxygen into the respiratory bag 100 .

The oxygen supply unit 400 may control the flow rate of oxygen supplied to the inside of the respiratory bag 100 for the purpose of adjusting the air pressure of the respiratory bag 100 together with the pressure regulator 500 (Not shown). The flow rate control unit (not shown) may be provided with various configurations such as a pressure reducing valve and a constant pressure reducing valve that can control the flow rate of oxygen supplied into the breathing chamber 100 .

In addition, the oxygen supply unit 400 may include oxygen supply means such as an oxygen compression vessel or an oxygen generator to supply oxygen into the respiratory sac 100, wherein the oxygen supply means includes a respiratory bag 100 ) Any device capable of supplying fresh oxygen to the inside of the device can be used. However, it is advantageous that the oxygen supply means is formed to have a minimum size that facilitates portability so that the user can move quickly in an emergency. In this case, since oxygen is regenerated in the respiratory bag 100, This is possible because the capacity of the supply means can be minimized.

The oxygen discharge port of the oxygen supply means may be provided with a decompression means for regulating the supply pressure of oxygen discharged from the oxygen supply means. The pressure reducing means may adjust the pressure of the user in consideration of the user's respiration amount, the oxygen remaining amount in the respiratory bag 100, etc. However, the present invention is not limited thereto. In case that a large amount of oxygen should be supplied because the user does not easily breathe, Of oxygen can be supplied.

Oxygen introduced through the oxygen supply unit 400 flows into the connection unit 220 and is mixed with the air inside the connection unit 220 so that the oxygen can be used by the user to breathe or into the inside of the respiratory support 100 And is mixed with the air inside the respiratory sac 100 to be used by the user to breathe.

A filter unit 300 is provided between one end of the respiration unit 200 constructed as described above and more specifically between the one end of the connection unit 220 and the air hole 221 formed for the flow of air inside the respiratory bag 100 .

Here, the filter unit 300 is a component for removing or recycling carbon dioxide or moisture in the air discharged during a user's breathing. As described above, in the embodiment of the oxygen mask according to the present invention, But it is needless to say that the present invention is not limited to the one side of the respiration unit 200 but may be provided within the respiratory perfusion unit 100, and thus the scope of the right is not limited.

The filter unit 300 may include at least one of the filter unit 310 and the oxygen generating unit 320.

The filter unit 310 is a component that helps the user's breathing by removing carbon dioxide or moisture generated during the user's breathing, i.e., carbon dioxide or moisture contained in the user's exhalation.

The filter unit 310 may be provided at one side of the inside of the breathing portion 100 to absorb carbon dioxide and moisture from the air stored in the breathing portion 100, have. As another embodiment, the filter unit 310 may be formed at one side of the interior of the connection portion 220 and the respiratory bag 100, respectively, so that the filter unit 310 may absorb moisture and carbon dioxide through the second or some other steps.

The oxygen generating unit 320 is provided inside the connection unit 220 so as to be in contact with one surface of the filter unit 310 to generate oxygen through chemical reaction with carbon dioxide or water contained in the user's exhalation.

Since the oxygen generating unit 320 must generate oxygen through exhalation and chemical reaction of the user, the oxygen generating unit 320 first passes through the oxygen generating unit 320 before the exhalation passes through the filter unit 310, It is advantageous to be provided to pass. That is, the oxygen generating unit 320 may be provided in the filter unit 300 in correspondence with the direction of the air flow inside the respiratory bag 100 during the breathing of the user.

Since the detailed configuration and principle of the oxygen generating unit 320 for generating oxygen through exhalation and chemical reaction of the user are commonly used in the art, detailed description thereof will be omitted.

The oxygen generating unit 320 may be provided at one side of the inside of the respiratory bag 100 so as not to be disposed inside the connection unit 220 according to the usage mode as in the filter unit 310, Oxygen can be generated through chemical reaction. It is apparent that the oxygen generating unit 320 may also be formed inside the connecting part 220 and at one side of the inside of the respiratory sac 100 to generate oxygen over a second or a certain number of steps.

In addition, the oxygen generating unit 320 may generate oxygen by an amount corresponding to the amount of carbon dioxide or moisture removed through the filter unit 300, And a pressure regulator 500 to be described later, to regulate the air pressure inside the respiratory bag 100.

Meanwhile, a one-way valve (not shown) may be further provided on one side of the filter unit 310 for facilitating venting of the user. Such a one-way valve emits an exhalation during the user's breath but prevents the inspiration from the inspiration.

As described above, the oxygen mask according to an exemplary embodiment of the present invention can be modified into various forms. For a more detailed description, .

The respiratory unit 200 having the above-described configuration is not integrated with the respiratory bag 100, but may be a separate member inside the respiratory bag 100. That is, in case that the wearer is not smooth when the breathing part 100 and the breathing part 200 are integrally formed according to the skeleton of the user, the breathing part 200 may be positioned in the breathing part 100 at a predetermined interval So that it is possible to use a separate member.

In this case, one side of the respiratory part 200 and one side of the inside of the respiratory bag 100 are connected to each other through the connecting member 230. It is needless to say that the shape and the material of the connecting member 230 are not limited.

In an embodiment of the oxygen mask according to the present invention, as described above, the pressure of at least one of the respiratory bag 100 and the filter unit 300 may be adjusted to control the internal air pressure of the respiratory bag 100, The control unit 500 may be further included.

In this case, the pressure regulator 500 may be configured in any form as long as it regulates the internal air pressure of the respiratory bag 100, but will be described in detail below with a check valve as an example.

The check valve prevents the air from the outside of the respiratory bag 100 from flowing into the inside of the respiratory bag 100. The check valve can be configured to discharge only the air inside the respiratory bag 100 to the outside, The check valve is opened and the air inside the respiratory bag 100 is partially discharged to the outside when the pressure inside the respiratory bag 100 is higher than a predetermined pressure. So as not to be discharged to

Meanwhile, in an embodiment of the oxygen mask according to the present invention, when the user holds the replacement time of the filter unit 300, which is confirmed by measuring the amount of carbon dioxide or moisture that is removed or recycled through the filter unit 300, And a communication unit 600 mounted on the respiratory bag 100 to inform the user through the portable wireless terminal.

At this time, the communication unit 600 notifies the replacement time of the filter unit 300 through the portable wireless terminal that the user holds, and notifies the replacement time of the filter unit 300 through the portable wireless terminal held by the user And may be configured to determine a reference of replacement timing of the filter unit 300 using the input information.

That is, since the replacement time of the filter unit 300 may be relatively long when the amount of respiration is small, such as a child or an elderly person, the standard provided in the communication unit 600 may be changed using the portable wireless terminal, You will not be frequent.

Next, referring to FIG. 4, the operation (use mode) and effect of one embodiment of the oxygen mask according to the present invention will be described in detail. Here, FIG. 4 is an operational state diagram showing the air flow in the embodiment shown in FIG.

The reason for recycling the user's exhalation in the respiration chamber 100 will be described below before explaining the use of the oxygen mask 10 according to the present invention.

As shown in the following Table 1, the concentration of oxygen contained in the atmosphere is generally about 20%, the amount of oxygen used in the human body by inhalation when the person breathes is about 4% to 5% Oxygen close to% is released to the outside of the human body through the exhalation of the person.

Drowsiness (%) Exhalation (%) nitrogen 80 80 Oxygen 20 15 carbon dioxide - 5

Therefore, if the oxygen discharged from the exhalation when the person breathed is recycled, the supply amount of oxygen supplied from the oxygen supply means can be minimized, and if the oxygen supply means of the same capacity is used, the user's survival time can be dramatically prolonged have.

The oxygen mask according to an embodiment of the present invention will now be described in more detail with reference to the use of an embodiment of the oxygen mask according to the present invention and the flow of air according to the user's breathing using the same. The user is not able to breathe by sucking in the outside air.

First, the user opens one embodiment of the oxygen mask according to the present invention, which is stored in a storage case or a carry-on bag, and wears the breathing portion 200 in accordance with the user's respirator.

In this case, when the respiratory part 200 is composed of the face part 210 and the connection part 220, the face part 210 is brought into close contact with the user's respirator, and then the head part 210 The user may pull the head strap after the bag is put on the skeleton of the user so that the face portion 210 is firmly fixed to the face of the user as much as possible.

If the respiration unit 200 has a mouthpiece or nose piece shape, the respiratory unit 200 is inserted into the mouth or nose so that the respiratory unit 200 is worn. As described above, although the wearing method is different according to the shape of the respiration unit 200, the point of first wearing the respiration unit 200 is the same.

Next, the user's head is inserted into the inside of the respiratory bag 100 through the opening 110 of the respiratory bag 100 to wear the respiratory bag 100, and then the opening 110 of the respiratory bag 100 And intercepts or minimizes the interflow of air inside and outside the respiratory tract 100 through the throttling portion 111. When the tightening part 111 is formed of an elastic band or the like formed along the opening part 110, the elastic band tightens the neck part of the user through the elasticity of the elastic band to seal the opening part 110 without any special operation. If the tightening part 111 is made of a pull string, the opening 110 may be sealed to the utmost by tightening the string as much as possible within the range where the user can breathe.

In this case, even if the opening 110 of the respiratory bag 100 is not completely sealed, the pressure inside the respiratory bag 100 is relatively higher than the pressure outside the respiratory bag 100, The outside air does not flow into the respiratory space 100 through the opening 110 until the supply of oxygen supplied from the oxygen supply means is cut off.

Next, the decompression means provided in the oxygen supply means is operated to control the supply amount of oxygen supplied from the oxygen supply means. In this way, the oxygen supply means, which is controlled in accordance with the operation of the decompression means, continuously flows a predetermined amount of oxygen through the flow path 500 and the oxygen inflow portion 400 and is supplied to the inside of the breathing portion 100, .

At this time, the decompression means can change the oxygen supply amount according to the amount of the user's breathing, and cut off the supply of oxygen through the decompression means or continuously supply oxygen until the oxygen stored in the oxygen supply means is completely consumed. Also, when the product is shipped, it is possible to fix the oxygen supply at a constant flow rate so that the flow rate can not be adjusted when using the product.

For example, when the oxygen mask 10 is first worn, a certain amount of oxygen must be supplied to the inside of the respiratory bag 100, so that the pressure reducing means is fully opened to allow a large amount of oxygen to be supplied to the respiratory bag 100, It is advantageous to reduce the supply amount of oxygen by adjusting the decompression means according to the volume of the user after the oxygen is supplied to the inside.

4, when the oxygen inflow unit 400 is coupled to one side of the respiration unit 200, the oxygen inflow unit 400 is connected to the oxygen supply unit 400, A part of the oxygen supplied through the oxygen inflow part 400 is directly introduced into the user's respirator through the respiration part 200 and part of the oxygen is supplied to the respiratory part 100 through the through hole 221 formed in the respiration part 200. [ As shown in FIG.

Next, as shown in [Table 1], about 5% of oxygen is absorbed by the user and then about 15% of oxygen is re-emitted by the user's exhalation.

Next, the user's exhalation passes through the filter unit 310 provided in the respiration unit 200, and water and carbon dioxide contained in the exhalation can be removed through the filter unit 310.

In addition, the moisture and carbon dioxide contained in the exhalation during the passage of the exhalation through the oxygen generating unit 320 can generate oxygen through a chemical reaction with the chemicals contained in the oxygen generating unit 320, 320). &Lt; / RTI >

As described above, the exhalation with moisture and carbon dioxide removed is stored in the respiratory passageway 100 and can be reused for the user's respiration. The newly generated oxygen is also stored in the respiratory passageway 100 through the oxygen generating unit 320 Can be used for user's breathing.

If the filter unit 300 is not provided on one side of the respiration unit 200, the user's exhalation is stored in the respiratory space 100 through the through hole 221 formed on one side of the respiration unit 200 .

The filter unit 310 and the oxygen generating unit 320 constituting the filter unit 300 are not provided on one side of the respiratory unit 200 but may be provided on one side of the respiratory unit 100, Moisture and carbon dioxide in the air stored in the nacelle 100 can be removed or oxygen can be generated.

Through the above-described process, oxygen, oxygen generated through the oxygen generating unit 320, and oxygen supplied through the oxygen supplying means are mixed and stored in the breathing portion 100 through the user's exhalation.

In this way, in addition to the oxygen supplied from the oxygen supply means, the oxygen discharged through the user's exhalation and the oxygen generated through the oxygen generating unit 320 are stored in the inside of the breathing chamber 100 without being discharged to the outside Even if oxygen supply means of the same capacity is used as compared with the conventional mask, the user's life time is dramatically increased. At this time, the concentration of carbon dioxide discharged from the user's exhalation should be kept below 3%.

Since the air in the respiratory bag 100 is not easily discharged to the outside while oxygen is supplied from the outside to the inside of the respiratory bag 100 through the above-described process, the pressure of the respiratory bag 100 continuously increases . That is, since the opening 110 of the respiratory sac 100 is tightened as much as possible through the throttle 111, the flow of air is suppressed as much as possible, so even though a small amount of air can be exhausted through the gap of the opening 110, The pressure of the inside of the main body 100 can be continuously increased.

In this case, it is the pressure regulating part 500 which can be constituted by a check valve.

That is, as described above, since the pressure inside the respiratory bag 100 is relatively higher than the external pressure when the pressure inside the respiratory bag 100 rises, it is possible to prevent the inflow of outside air , The user may feel uncomfortable when the pressure is higher than a predetermined pressure. In order to solve this problem, the opening and closing operation of the check valve is repeatedly performed according to the user's breathing pressure in the breathing chamber 100.

Meanwhile, in an embodiment of the oxygen mask according to the present invention, it may be necessary to replace the filter unit 300 in some cases. The communication unit 600 is used at this time, The description of the configuration of one embodiment of the oxygen mask according to the invention will be replaced.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, It is self-evident to those of ordinary skill in the art. Accordingly, such modifications or variations should not be individually understood from the technical spirit and viewpoint of the present invention, but they should also be included in the claims of the present invention.
