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 large oxygen containers.

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.

1 to 3, an embodiment of the oxygen mask according to the present invention and modifications thereof may include a respiratory bag 100, an oxygen supply 200, and a discharge 300 have.

First, the breathing receptacle 100 is provided to surround the user's head, thereby preventing external air from entering the inside of the breathing receptacle 100 and preventing the user's head from being exposed to flames, dust, to be.

The breathing pad 100 is formed to surround the user's head through an opening formed at one side. It is advantageous to wrap the entire head of the user for the safety of the user, but the present invention is not limited thereto. It may be formed so as to surround only one part of the nose and the mouth periphery.

In addition, the breathing receptacle 100 may be made of any material that can prevent air from flowing between the outside and the inside, so that it is natural that 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.

As described above, at one side of the breathing receptacle 100, which may be made of various materials, an opening is formed in which the user wears or removes the breathing receptacle 100 as described above. The user can wear the respiratory bag 100 by inserting his or her head into the respiratory bag 100 through the opening or remove the respiratory bag 100 by pulling the head from the bag 100 through the opening after use.

The opening portion may be provided with a throttle portion 110 to prevent external air from entering the inside of the breathing receptacle 100 through the opening after the wearer wears the breathing receptacle 100 by inserting the head.

The tightening portion 110 is provided along the opening portion and is tightly attached to one side of the user's neck or head so as to tighten the neck or the head or the head portion to block air flow inside and outside the breathing portion 100, Thereby minimizing the flow of air.

The throttle unit 11 may be of any type as long as it can tighten the opening to prevent the air from flowing easily. However, the throttle unit 11 may be formed of an elastic band provided along the opening, 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.

Below the viewing window 120 in the respiratory tract 100 may be a face 130 that is in communication with other components such as the exhaust unit 300 and the inflow unit 400 which will be described later. The components will first be described in greater detail below, and then the respiration section 600 will be described in more detail.

Meanwhile, the oxygen supply unit 200 is provided inside the respiratory bag 100 to supply oxygen for respiration of the user. If the oxygen supply unit 200 can supply oxygen such as an oxygen compression vessel or an oxygen generator, It is natural that this does not limit the scope of the rights.

However, it is advantageous that the oxygen supply unit 200 is formed to have a minimum size that is easy to carry, so that the user can quickly move in an emergency. In addition, the oxygen supply unit 200 can be reused by re- The size can be further minimized.

The oxygen supply unit 200 may be detachably mounted on the outside of the respiratory unit 600 to be provided inside the respiratory bag 100.

At this time, the oxygen supply unit 200 can be stably mounted on the respiration unit 600 by the mounting unit 210 such as a band having elasticity, but if the size of the oxygen supply unit 200 is minimized as described above, (210) will not necessarily be required.

In addition, the oxygen supply unit 200 may include a flow rate control unit 220 that allows the user to supply oxygen at a predetermined flow rate. At this time, the flow rate control unit 220 controls the flow rate of oxygen discharged from the oxygen supply unit 200 to supply oxygen to the user at a predetermined flow rate.

The flow rate control unit 220 is provided in the oxygen supply unit 200 to control the flow rate of oxygen supplied to the user so that excessive oxygen is not supplied to the user.

The oxygen supply unit 200 includes a safety unit 230 that automatically discharges oxygen when the temperature inside the respiratory sac 100 is higher than a predetermined temperature or when the internal pressure of the oxygen supply unit 200 is higher than a preset pressure ).

Such a safety unit 230 is problematic in that the oxygen supply unit 200 is installed in the respiration unit 600 surrounding the user's nose or mouth and thus the risk of injury to the user at the time of explosion may be very high, As shown in Fig. Particularly, in order to minimize the size of the oxygen supply unit 200, the safety unit 230 may be necessary when the oxygen supply unit 200 is configured as an oxygen compression vessel.

The oxygen supply unit 200 may be configured such that when purified air containing oxygen can not be supplied to the user through the inflow unit 400 to be described later or the oxygen recycled through the filter unit 500 It is considered to be a more meaningful constituent in the embodiment of the oxygen mask according to the present invention, considering the case where it can not be supplied to the user.

In other words, if the air outside the respiratory tract 100 contains oxygen to some extent, the air can be purified through the inflow section 400 to be supplied to the user, If the outside air lacks oxygen, the safety of the user can not be guaranteed even if there is an inflow unit 400 to be described later.

However, since the embodiment of the oxygen mask according to the present invention includes the oxygen supply unit 200, the safety of the user can be assured regardless of whether oxygen is lacking in the air outside the respiratory sac 100.

The discharge unit 300 is a component installed in the respiratory bag 100 to discharge the air discharged from the user during respiration to the outside of the respiratory bag 100.

As described above, since the breathing portion 100 is provided to surround the head of the user, the inside of the breathing portion 100 will be a substantially airtight space, so that the air discharged during the breathing of the user is supplied to the breathing portion 100 The internal pressure of the respiratory bag 100 is increased to cause a gap between the inside and the outside of the respiratory bag 100. This results in the effect of the respiratory bag 100 and the effect of the oxygen mask 100 according to an embodiment of the present invention The effect will deteriorate.

Although it is possible to recycle part of the air discharged during breathing by the user through the filter unit 500 as described later, in some cases, the filter unit 500 may not be included, (300) is required in an embodiment of the oxygen mask according to the present invention.

However, if outside air that has not been purified by the respiratory bag 100 comes in through the discharge portion 300, the effect of the oxygen mask 200 according to an embodiment of the present invention may be degraded even if the oxygen supply portion 200 is included. Of course.

Therefore, it is advantageous that the discharging unit 300 includes a one-way valve for discharging the air discharged from the user during respiration to the outside of the respiratory bag 100 while blocking inflow of the outside air.

Although the discharge unit 300 has an effect of preventing the internal pressure of the respiratory bag 100 from being increased, the oxygen supply unit 200, the inflow unit 400 and the filter unit 500, which will be described later, The oxygen mask according to an embodiment of the present invention may further include a pressure regulator 700 to prevent the internal pressure of the respiratory vest 100 from increasing.

The pressure regulator 700 may be installed in the respiratory bag 100 to control the internal air pressure of the respiratory bag 100 so that the structure and the shape of the pressure regulator 700 are not limited. It can be mounted.

For example, the pressure regulator 700 may fill the internal space of the respiratory bag 100 with air discharged from a user during a user's breathing period, open the ventilation part 100 to discharge a part of the air discharged from the user, And a check valve for blocking the inflow of outside air into the respiratory bag 100. The check valve may be installed near the discharge unit 300 as shown in FIG.

As described above, the oxygen mask according to the present invention including the respiratory bag 100, the oxygen supply unit 200, and the discharge unit 300 includes the inflow unit 400, the filter unit 500, (600). ≪ / RTI >

First, the inflow unit 400 is a component installed in the respiratory bag 100 to introduce purified air containing oxygen into the inside of the respiratory bag 100 for respiration of the user.

That is, the inflow unit 400 may not necessarily be necessary if only the oxygen supply unit 200 described above can supply oxygen to the user. However, if purified air containing oxygen is supplied to the user through the inflow part 400, the amount of oxygen flowing into the oxygen supplying part 200 may be reduced, thereby increasing the service life of the oxygen supplying part 200 Or conversely, the capacity of the oxygen supplier 200 can be reduced.

The inflow unit 400 may include a first filter 410 for introducing the purified air containing oxygen into the inside of the respiratory bag 100. Unlike the secondary filter 510 provided in the filter unit 500, which will be described later, the primary filter 410 functions to filter harmful components in the external air supplied to the user. It is natural that this does not limit the scope of the rights.

The inlet portion 400 is provided on the upper side of the face portion 130 and the outlet portion 300 described above is provided on the lower side of the face portion 130. This is because the temperature of the air discharged from the outlet portion 300 flows And the temperature of the air to be introduced into the unit 400 is relatively higher than the temperature of the air flowing into the unit 400. However, it is needless to say that the position of the inflow part 400 and further the position of the discharge part 300 can be changed sufficiently according to the shape of the face part 130. [

When the oxygen mask according to an embodiment of the present invention includes the inflow part 400, the amount of the purified outside air introduced through the inflow part 400 corresponds to the amount of oxygen supplied from the oxygen supply part 200, It is advantageous to adjust it to the enemy.

In other words, as described above, in the embodiment of the oxygen mask according to the present invention, since the inflow part 400 is included, the life of the oxygen supply part 200 can be increased or the capacity of the oxygen supply part 200 can be reduced. It may be more convenient for the user if it is possible to adjust the life or capacity of the oxygen supplier 200 according to the user or the surrounding conditions and conditions.

Meanwhile, the filter unit 500 is provided inside the respiratory bag 100 to remove or recycle the carbon dioxide or moisture contained in air discharged from the user during respiration to supply the user with the user.

If the filter unit 500 can completely remove or recycle the carbon dioxide or moisture contained in the air discharged during the user's breathing, the discharge unit 300 described in the embodiment of the oxygen mask according to the present invention may be replaced The filter unit 500 may be included with the discharge unit 300 since the filter unit 500 may have a limit to completely remove the carbon dioxide or moisture contained in the air discharged during the user's breathing.

The filter unit 500 may include at least one of the secondary filter 510 and the oxygen generating unit 520.

The secondary filter 510 is a component that helps the user's breathing by removing carbon dioxide or moisture generated during the user's breathing, that is, carbon dioxide or moisture contained in the user's exhalation.

The second filter 510 may be provided with a one-way valve (not shown) configured to discharge the exhalation of the user to the outside of the respiratory bag 100 and prevent the outside air from flowing into the respiratory bag 100, And may be configured to communicate with the discharge portion 300 if the oxygen mask according to the present invention is included and configured together with the discharge portion 300 in one embodiment.

On the other hand, the oxygen generating unit 520 is provided to be in contact with one surface of the secondary filter 510 to generate oxygen through chemical reaction with carbon dioxide or water contained in the user's exhalation.

Since the oxygen generating unit 520 generates oxygen through exhalation and chemical reaction of the user, the oxygen generating unit 520 first passes through the secondary filter 510 before passing through the secondary filter 510, 510). ≪ / RTI > That is, the oxygen generating unit 520 may be provided in the filter unit 500 corresponding to the air flow direction inside the breathing chamber 100, which is generated when the user breathes.

 However, the detailed configuration and principle of the oxygen generating unit 520 for generating oxygen through exhalation and chemical reaction of the user are commonly used in the art, and therefore, a detailed description thereof will be omitted.

The oxygen generating unit 520 may generate a predetermined amount of oxygen corresponding to the amount of carbon dioxide or moisture removed through the filter unit 500. The oxygen generating unit 520 may include the oxygen supplying unit 200 and the inflow unit 400 And the amount of oxygen supplied to the user through the oxygen sensor.

That is, the amount of oxygen supplied to the user through the filter unit 500, and more specifically, the amount of oxygen supplied to the user through the oxygen generating unit 520 is determined by the amount of oxygen supplied from the oxygen supplying unit 200 Can be complementarily adjusted in consideration of the amount of oxygen contained in the purified outdoor air flowing through the inflow section 400.

The respiratory unit 600 communicates with the oxygen supply unit 200, the discharge unit 300, the inflow unit 400, and the filter unit 500 described above and is provided inside the respiratory bag 100 And the inner side is formed so as to surround the user's nose or mouth, thereby functioning to assist the user's breathing.

5, the oxygen supply unit 200, the discharge unit 300, the inflow unit 400, and the inflow unit 400 may be omitted, instead of the respiration unit 600, as in the modification of the embodiment of the oxygen mask according to the present invention. The filter unit 500, and the like. In this case, however, the position of the user's nose or mouth is not opposed to the above-described components, and the possibility that the effect of the present invention is substantially lowered can not be excluded.

In other words, the respiratory part 600 will play the role of maximizing the effect of the present invention by allowing the position of the user's nose or mouth to be opposed to the aforementioned components.

In addition, the breathing unit 600 includes a mixing chamber in which oxygen supplied through the oxygen supply unit 200, oxygen introduced through the inlet unit 400, and air supplied from the filter unit 500 are mixed, Can also play a role.

Here, the role of the mixing chamber is to act as a respiratory bag (not shown) that is necessary for the user to retain enough air to be inhaled by the user during the initial breath, as will be described below with respect to the face portion 130, same.

That is, the oxygen supplied through the oxygen supply unit 200 through the respiration unit 600 serving as a mixing chamber, the oxygen supplied through the oxygen supply unit 200, and the air introduced into the inflow unit (not shown) 400 and the air supplied from the filter unit 500 is mixed.

In this regard, considering the modification shown in FIG. 5, in the modification shown in FIG. 5, there is no respiration unit 600 serving as a mixing chamber, A pocket (not shown) should be provided.

The respiratory part 600 can be closely attached to the user's nose or mouth through the fixed unit 610 provided inside the respiratory bag 100 and can be made to be symmetrical to the respiratory part 600 around the respiratory bag 100 By centering the weight through the prepared face portion 130, the user's nose or mouth can be wrapped more securely.

In this case, the face portion 130 is a component provided outside the respiratory bag 100, and may be formed extending substantially from the respiration portion 600, but may be variously configured without being limited thereto.

The face part 130 includes a discharge part 300 communicating with the outside of the respiratory bag 100 on the opposite side of the respiratory part 600 and a discharge part 300 communicating with the inflow part 400 In the form of an external shape of the respiratory bag 100.

The front face of the face portion 130 may additionally include various components necessary to use the user's nose or mouth, or various switches capable of controlling the operation of one embodiment of the oxygen mask according to the present invention.

A connection unit 132 that can be connected to a breathing bag (not shown) having enough air to be inhaled by the user during the initial breathing, or a beverage receptacle (not shown) May be provided on the front surface of the face portion 130.

As described above, there are various components for supplying oxygen to the user, such as the oxygen supply unit 200, the inflow unit 400, the filter unit 500, etc. In order to efficiently supply oxygen to the user due to their complementary relationship, An adjustment unit 134 may be provided on the front surface of the face portion 130 so that the user can selectively and manually adjust the manipulation.

In addition to the components described above, the oxygen mask according to an embodiment of the present invention or a modification thereof may further include an alarm unit 800.

At this time, the alarm unit 800 informs the user when the amount of oxygen that can be supplied from the oxygen supply unit 200 or the amount of oxygen contained in the air temporarily accommodated in the respiration unit 600 is smaller than a predetermined amount As an element, is provided to measure in real time the amount of oxygen that can be supplied from the oxygen supply unit 200 or the amount of oxygen contained in the air temporarily accommodated in the respiration unit 600.

The alarm unit 800 may measure the amount of oxygen that can be supplied from the oxygen supplying unit 200 according to the capacity of the oxygen supplying unit 200 or may measure the amount of oxygen contained in the air temporarily accommodated in the respiration unit 600 It is natural that the scope of the right is not limited, as long as it can measure the amount and alarm to the user in any form, anywhere.

The amount of oxygen used and disposed on the supply passage 240 or the opening hole 242, which is the path through which oxygen moves from the oxygen supply unit 200 to the respiratory unit 600, will be described in more detail, The amount of oxygen that can be supplied from the oxygen supply unit 200 can be measured by comparing the capacity of the oxygen supply unit 200 with the capacity of the oxygen supply unit 200 and the user can be notified of the amount of oxygen through the beeper.

Next, with reference to FIG. 4, the operation and effect of an embodiment of the oxygen mask according to the present invention, which can be configured as described above, or modifications thereof will be described in detail.

Here, FIG. 4 is a state diagram showing an air flow in an embodiment of the oxygen mask according to the present invention.

In addition, although the flow process of the air will be described in a time-wise manner for the sake of more detailed explanation, it is needless to say that the scope of the present invention is not limited by the temporal description of the flow process.

First, when a user is exposed to a toxic gas such as a fire, the user quickly sweeps the breathing portion 100 around the head (or face, as the case may be) So that it is no longer allowed to flow into the air-breathing portion 100 outside the breathing portion 100.

When the user breathes, inhalation and exhalation occur. In the inhalation, an air flow is generated in relation to the oxygen supply unit 200, the inflow unit 400, and the filter unit 500, , An air flow is generated in relation to the filter unit 500.

That is, when the user breathes and drinks, the purified air containing oxygen is introduced into the respiratory bag 100 through the inflow portion 400. At this time, oxygen is complementarily supplied from the oxygen supply part 200 according to the amount of oxygen contained in the purified external air flowing into the respiratory bag 100 through the inflow part 400.

In addition, when the user breathed out, air including carbon dioxide is discharged through the discharge part 300 to the outside of the breathing receptacle 100. At this time, some or all of the carbon dioxide discharged through the discharging unit 300 may be changed to oxygen due to the filter unit 500, and may be recycled when the user breathed and drinks. The oxygen or oxygen supply unit 200 included in the purified external air flowing into the respiratory bag 100 through the inflow unit 400 may be changed depending on the amount of oxygen to be changed through the filter unit 500, Is supplied complementarily.

In this way, an air flow is generated from the outside of the respiratory apparatus 100 to the inside or the inside of the respiratory apparatus 100 in order to enable the user to breathe, which is limited to the above-mentioned components provided only in the face 130, the respiratory unit 600, It is natural that the air flow is generated in the entire inside of the breathing chamber 100 rather than only air flow is generated so that the user can be more comfortable breathing.

Meanwhile, in the embodiment of the oxygen mask according to the present invention, since the filter unit 500 and the oxygen supply unit 200 are present, the use time of the conventional oxygen mask can be prolonged remarkably.

In other words, as can be seen in Table 1 below, the amount of oxygen contained in the user's air is generally about 20% of the air, but the oxygen (carbon dioxide emitted) 4.5%, and the remaining oxygen of about 15% is released to the outside of the human body through exhalation.

(Approximate% value) Drowsiness (%) Exhalation (%) nitrogen 80 80 Oxygen 20 15.5 carbon dioxide 0 4.5

Therefore, if the oxygen discharged from the exhalation when the person breathed through the filter unit 500 is recycled and the carbon dioxide discharged is changed to oxygen again, the use time of the oxygen mask can be prolonged remarkably, This will further increase the user's chances of survival.

However, as can be seen from Table 2 below using the oxygen supply unit 200, if the nitrogen can be replaced with oxygen, the use time of the filter unit 500 is further increased compared with the case of using only the filter unit 500 And thus the probability of the user's survival will be even higher.

(Approximate% value) Drowsiness (%) Exhalation (%) nitrogen 0 0 Oxygen 100 95.5 carbon dioxide 0 4.5

In addition, even when the oxygen supply unit 200 is used in a reduced size so as to be attached to the respiratory unit 600, the same effect as described above can be obtained. Therefore, As described above, an oxygen mask capable of maximizing portability and simplicity while flexibly coping with surrounding situations due to an extended use time can be realized through the present invention.

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.
