Technical Field

The present invention relates to a respiratory inflatable mask, and more particularly, to a respiratory inflatable mask configured to inflate a bladder within the mask to completely cover the head of a wearer and allow the wearer to breathe.

Background

Generally, in case of a fire, when a wearer is exposed to harmful gas (or smoke), gas masks are widely used to help people escape from the fire by enabling the wearer to breathe and protecting the life of the wearer.

Conventional gas masks are difficult to carry due to their large size and weight, and their gas canisters are also replaced periodically, which is a problem with gas masks. Therefore, those skilled in the art are interested in research on life saving equipment capable of securing its portability and usability and preventing the inhalation of harmful gas.

As part of this study, the present invention proposes a disposable gas mask having a tubular oxygen storage bag (patent document 1). As described above, the disposable gas mask of patent document 1 allows the tubular oxygen storage bag provided around the neck of the wearer to be inflated by the compressed air of the compressed air tank, prevents external smoke from flowing into the mask, and allows the wearer to inhale oxygen through the inhalation hose. Conventional disposable respirators can only ensure the visibility of the wearer via the sight glass of the respirator's hood, but it is difficult to ensure a predetermined space between the hood and the wearer's head.

Disclosure of Invention

Accordingly, the present invention has been made keeping in mind the above problems occurring in the related art, and the present invention is directed to a respiratory inflatable mask configured to assist a wearer in continuously breathing and to be inflated by an airbag through air (or oxygen) stored in a compressed air tank at one side of the airbag.

In order to achieve the above object, according to one aspect of the present invention, there is provided an inflatable mask for breathing, which may include a compressed air tank provided with first micro-holes and filled with compressed air, and an airbag; the bladder is disposed for fluid communication with the compressed air tank and is inflated by compressed air injected from the compressed air tank into the shape of a helmet to accommodate the head of a wearer.

In the present invention, the airbag may include: a first balloon portion on an outer peripheral surface thereof, the first balloon portion having a guide hole allowing inflow of compressed air; a second balloon portion disposed on an inner peripheral surface of the first balloon portion in fluid communication with the first balloon portion; an interior space portion for receiving a wearer's head; and an opening arranged at the lower part of the air bag.

In the airbag of the invention, a second micro-hole may be opened between the first airbag portion and the second airbag portion, and a third micro-hole may be opened in an inner peripheral surface of the second airbag portion.

In the present invention, the second micro-hole may be disposed near the opening, and the third micro-hole may be disposed at an upper portion of the inner space portion.

In addition, the guide hole of the present invention may have a sealing portion surrounding an inner circumferential surface of the guide hole.

The above and other objects, features, and advantages of the present invention will be more clearly understood from the following detailed description taken in conjunction with the accompanying drawings.

All terms or words used in the specification and claims have the same meaning as commonly understood by one of ordinary skill in the art to which the inventive concept belongs. It will be further understood that terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the relevant art and will not be interpreted in an idealized or overly formal sense unless expressly so defined herein.

According to the above-described invention, the airbag of the present invention can be inflated with air into the shape of a helmet opened at the lower portion due to the injection of air, thereby providing a hood capable of completely covering the head of a wearer.

Since the compressed air is filled in and inflates the air bag and the compressed air can be forcibly introduced to the inner space portion, the cover of the present invention has an advantage of maintaining the air bag in an inflated state and can help breathing during the time required for evacuation.

In addition, the airbag of the present invention is made of a transparent flame-retardant material, so that the airbag can ensure visibility of a wearer and smooth movement when worn.

In the present invention, air (or oxygen) stored in the compressed air tank is guided to the inner space portion of the airbag. Therefore, the airbag can prevent the inflow of harmful gas into the inner space portion, and can protect the head of the wearer by buffering the impact caused by the impact from the outside of the inflatable airbag.

Detailed Description

The above and other objects, features, and other advantages of the present invention will be more clearly understood from the following detailed description taken in conjunction with the accompanying drawings. With respect to reference numerals associated with components in the figures, the same reference numerals of the figures refer to the same or similar components. Additionally, in the description, details of well-known features and techniques are omitted so as to not unnecessarily obscure the presented embodiments. It will be understood that, although the terms first, second, etc. may be used herein to describe various elements, these elements should not be limited by these terms. These terms are only used to distinguish one element from another. In the drawings, some elements shown in the drawings are enlarged, omitted, or schematically shown, and the size of each element does not necessarily reflect the actual size.

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

Referring to fig. 1 to 3, the inflatable mask 1 for breathing according to the exemplary embodiment of the present invention is designed in a double-bladder structure so as to be worn on the head of a wearer, i.e., the inflatable mask 1 is sized and shaped to be inflated to fully accommodate the head of the wearer.

The inflatable mask 1 for breathing of the present invention is composed of a compressed air tank 10 for storing compressed air and an airbag 20, and the airbag 20 is in fluid communication with the compressed air tank 10.

As shown in the drawings, the compressed air tank 10 has a cylindrical shape, which can be filled with compressed air at a pressure higher than atmospheric pressure, and is detachably disposed at the outer circumferential surface of the airbag 20. The compressed air may include a medium, such as oxygen or air, that may allow the bladder 20 to inflate and allow the wearer to breathe. The compressed air tank 10 has first minute holes 11, and the first minute holes 11 guide the compressed air filled inside the compressed air tank to the air bags 20. The first micro-holes 11 reduce the flow path of the compressed air when the fluid passes through the orifice, so that the decompression effect due to the pressure drop between the inlet of the first micro-holes 11 (i.e., the inside of the compressed air tank) and the outlet of the first micro-holes 11 (i.e., the outside of the compressed air tank) can be expected. As described above, the first micro holes 11 may be outflow paths that guide the compressed air from the compressed air tank 10 to the air bags 20, and the first micro holes 11 may be used as inflow paths that inject the compressed air into the compressed air tank, if necessary.

As shown, the bladder 20 may be formed in a shape similar to a helmet having a predetermined size, which may accommodate the head of a wearer. In addition, the bladder 20 may also be formed in various shapes, such as a hemispherical shape and a conical shape that may cover the head of the wearer. That is, the airbag 20 may be expanded through an injection process of the compressed air discharged from the compressed air tank 10, and the airbag 20 completely covers the head of the wearer. The airbag 20 has a guide hole 21, the guide hole 21 being provided on an outer circumferential surface of the airbag so that the airbag can be in fluid communication with the compressed air tank 10, and the airbag has an opening 23, so that the airbag is expanded in the shape of a helmet when air is injected, and a lower portion thereof has an opening. The wearer's head can enter the interior space portion 22 of the airbag 20 through the opening 23. The guide hole 21 is opened at the upper portion of the airbag 20, but is not limited thereto, and may be opened at the side portion of the airbag 20.

The guide hole 21 may have a sealing portion 26 provided around an inner circumferential surface of the guide hole 21. The guide hole 21 may be disposed to overlap the first fine hole 11 of the compressed air tank 10 so that the state between the air bag 20 and the compressed air tank 10 may be hermetically sealed via the sealing portion 26. In addition, the material of the seal portion 26 may be configured to be able to fix the position of the guide hole of the airbag 20 to the outer circumferential surface of the compressed air tank 10, and is, for example, a seal tape and a seal adhesive.

In particular, the inflatable mask 1 for breathing according to the exemplary embodiment of the present invention is constructed in a dual balloon structure having a first balloon portion 20a and a second balloon portion 20 b. As described above, the airbag 20 has the first airbag section 20a formed in the shape of a helmet and the second airbag section 20b inner circumference disposed along the circumference of the inner circumferential surface of the first airbag section 20 a. The first and second balloon portions 20a, 20b are in fluid communication with each other. Therefore, since the first and second air bag portions are filled with the compressed air, the cover of the present invention can have a double air layer. The airbag 20 has second micro-apertures 24 between the first and second airbag portions 20a, 20b so that the first and second airbag portions 20a, 20b can be connected to and in fluid communication with each other. Here, the second micro-hole 24 may be disposed near the opening 23 of the airbag 20. In addition, the second balloon portion 20b has third micro holes 25 opened on the inner circumferential surface of the second balloon portion 20b, and the second balloon portion 20b may be in fluid communication with the inner space portion 22. Preferably, the third minute hole 25 is provided at an upper portion of the inner space portion 22, i.e., on the head of the wearer.

An exemplary breathable, inflatable mask 1 according to the present invention may be placed on the head of a wearer in the following manner, but is not limited thereto.

In the case of a fire, as shown in fig. 4, when the wearer loosens the knots of the fastening tapes 2 attached to the rolled cover 1, the airbag 20 is released from the outer circumferential surface of the compressed air tank 10. Therefore, the cover 1 of the present invention can release the contact of the air bag 20 by the first minute hole 11 of the compressed air tank 10. That is, the first bag portion 20a is inflated via air injected from the compressed air tank into the first bag portion 20a of the bag, so that the cover of the present invention can form the inner space portion 22 that can accommodate the head of the wearer. As described above, the first bladder portion 20a is expanded into the shape of the helmet and decompressed for the first time while being filled with the compressed air through the first micro-holes 11. Then, the compressed air decompressed for the first time is injected into the second bladder portion 20b through the second micro holes 24 to inflate the second bladder portion 20 b. In addition, the second balloon portion 20b is inflated by the compressed air decompressed again through the second micro holes 24. Since the second micro holes 24 are spaced apart from the first micro holes 11 and the second micro holes 24 are disposed close to the opening 23 as described above, the compressed air can be guided to the second airbag portion 20b installed as the rear portion after completely inflating the first airbag portion 20 a. In addition, the compressed air inflates the first air bag portion 20a from the upper portion while forcibly moving down to the second micro holes 24 from the guide holes 21, so that the air bag can be easily covered around the head of the wearer. Since the second micro holes 24 are disposed close to the opening 23, the second bag portion 20b inflates from below. As a result of the above process, the inner diameter of the opening 23 is reduced. Therefore, it is possible to effectively prevent the inflow of the external harmful gas or smoke into the inner space portion 22 of the airbag 20. In the cover 1 according to the present invention, the compressed air, which is decompressed again and filled in the second air bag portion 20b, is forcibly guided to the internal space portion 22 via the third minute holes 25. The compressed air directed to the interior space portion 22 may be depressurized sufficient to allow the wearer to breathe and be continuously supplied with breaths for a predetermined time (e.g., 5 minutes or more) required for evacuation. The third micro-holes 25 are disposed above the wearer's head as shown in the drawing, and may discharge depressurized air (or oxygen) downward to prevent external harmful gas or smoke from flowing through a gap between the wearer's neck and the opening 23. In addition, the third minute hole 25 can forcibly push the exhalation of carbon dioxide heavier than air, which occurs during breathing, to the opening 23.

Alternatively, the inflatable cover for breathing 1 according to the exemplary embodiment of the present invention has the airbag 20 made of a transparent flame retardant material, thereby sufficiently securing visibility of the wearer and being resistant to high temperature. As shown, the airbag 20 covers the entire head of the wearer, and thus, in case of fire, the wearer can see the side, upper, lower, and front portions with the naked eye. The inflatable mask for breathing of the present invention can protect the head of a wearer from external impact by the air bag 20 inflated by the injection of air through the air layer. Since the inner space portion of the space between the wearer's face and the airbag is filled with fresh oxygen or air, contact between the inner face surface of the airbag and the face can be minimized and dew condensation due to a temperature difference can be prevented.

The inflatable respiratory mask according to the present invention is not limited to the double balloon structure, and may additionally include at least one balloon portion on an inner peripheral surface of the second balloon portion to be in fluid communication with the second balloon portion.

Fig. 4 shows a state of an inflatable type mask for breathing in which a balloon in which gas has been discharged is wound around an outer circumferential surface of a compressed air tank according to an exemplary embodiment of the present invention. When the outer circumferential surface of the compressed air tank 10 is wound by the air bag 20, the first minute holes (11; see fig. 1) are sealed by the air bag, thereby preventing the inflow of the compressed air from the compressed air tank in advance. Then, as shown in the drawing, the airbag 20 may be maintained in a wound state around the circumference of the compressed air tank 10 by the fixing band 2. The present invention does not require a separate pressure valve (now shown) required to discharge the decompressed compressed air of the compressed air tank 10 to the air bag 20, and is constructed of a simple structure such that the first minute hole 11 can be opened or closed by the air bag 20.

As described above, when the fastening band 2 is loosened, the wearer can put the mask 1 on the head since the compressed air is injected from the compressed air tank 10 to the air cell 20 and inflates the air cell 20.

Although preferred embodiments of the present invention have been described above for illustrative purposes, the respiratory inflatable mask according to the present invention is not limited thereto, and those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope and spirit of the invention as disclosed in the accompanying claims.

All modifications and variations of the present invention are within the scope of the invention, and the scope of the specific protection of the invention will be clearly defined by the scope of the appended claims.
