Description

Oxygen Respirator {OXYGEN RESPIRATOR}

The present invention relates to a ventilator.

A respirator is a type of equipment that artificially supplies oxygen to the user. These oxygen respirators are not only used to safely protect people in the process of evacuation in the event of a disaster such as fire, leakage of toxic gas, lack of oxygen, terrorism, etc., but also help paramedics safely perform rescue activities. It also plays a supporting role.

On the other hand, such an evacuation process or rescue process may continue for a long time, but in the conventionally proposed oxygen respirators, a significant number of vortexes were generated in the piping of the oxygen respirator due to the inhalation passage not being separated.

Due to this, the oxygen respirator is overheated in the process of using the respirator, and there is a problem in which the user suffers from inconvenience in wearing it for a long time. Accordingly, there is a need for a respirator capable of maintaining a temperature suitable for use by a user even when worn for a long period of time.

Referring to Figures 2a and 2b, the oxygen respirator 10 according to the present invention, the adsorbent 150 for adsorbing carbon dioxide (CO ₂ ) is disposed in the intake pipe 120.

As described above, since the intake air should have a lower composition ratio of carbon dioxide than the expiration air, the adsorbent 150 may be disposed in the intake pipe 120 to lower the carbon dioxide molar ratio in the gas.

In addition, by disposing the adsorbent 150 on the intake pipe 120 as described above, the exhaled air and the intake air are separated and moved through the exhalation pipe 110 and the intake pipe 120 during the breathing process of the user. It is possible to prevent the vortex generated inside the unit 100, and through this, it is possible to provide an effect of preventing overheating of the respirator 10.

In one embodiment, the adsorbent 150 is, for example, zeolite, but is not limited to the above example, and can be easily adopted by a person skilled in the art and can adsorb carbon dioxide. All sides of the adsorbent 150 should be interpreted as belonging to the scope of the present invention.

Referring to Figures 2a and 2b in one embodiment, the oxygen respirator 10 includes a first pipe 130 disposed at one end of the body portion 100 and a second pipe 140 disposed at the other end. can do. The first pipe 130 fluidly connects a respirator worn by a user (not shown) and the body portion 100, and the second pipe 140 connects the breathing bag portion 300 and the body portion ( 100) is fluidically connected.

At this time, being fluidly connected means that when a user uses a respirator, breathing gas (exhalation or intake) passing through the main body is connected so that it can flow into or flow out from a specific part to another part.

In one embodiment, by including the first pipe 130 and the second pipe 140, when the user uses the respirator 10 using a breathing mask (not shown), the respiratory gas is the first pipe 130 ) After passing through the body portion 100, it may flow into the breathing bag portion 300 through the second pipe 140.

Through this, when the user of the oxygen respirator 10 exhales (exhalation), the exhaled air passes through the exhalation pipe 110, but when the user inhales (inhalation), the passage control unit 115 controls the flow of air. It is possible to prevent intake air from flowing into the expiratory pipe 110 by blocking the inflow.

Referring to FIG. 2B, in one embodiment, the intake pipe 120 is a second passage control unit 125 for controlling the movement of intake air at one end of the second pipe 140 connected to the breathing bag unit 300 side. ) may be included. When the user breathes in (inhalation), the second passage control unit 125 that controls the movement of the intake air allows intake air to flow into the intake pipe 120, but when the user exhales (exhalation), 2 The passage control unit 125 is not opened so that it is possible to prevent exhaled air from flowing into the intake pipe.

Referring to FIG. 2B , in another embodiment, a first passage control unit 115 for controlling the movement of exhaled air may be further included at one end of the first pipe 130 side of the exhalation pipe 110 . By further including the first passage control unit 115 for controlling the movement of the exhaled air, most of the intake air is prevented from flowing into the exhalation pipe 110 during the breathing process, so that most of the intake air is removed from the intake pipe 120. and ultimately allow carbon dioxide in the intake air to be adsorbed by the adsorbent 150 in the intake pipe 120.

In one embodiment, the passage control unit 115 may use a unit that moves gas in only one direction, and may include, for example, a check valve that moves gas in only one direction, but is not limited to the above example. No, all units that move a gas that can be easily selected by a person skilled in the art in one direction should be interpreted as belonging to the scope of the present invention.

However, if the environment in which the oxygen respirator is used is overheated or supercooled, and excessive moisture exists in the respirator, the user may feel uncomfortable because the air is supercooled or overheated.

Accordingly, by further including a desiccant (not shown) inside the main body 100, it is possible to control the humidity in the respiratory gas, and through this, it is possible to provide an effect of controlling impurity particles that may be generated as moisture in advance, , Ultimately, even if the user uses a respirator for a long time, a more comfortable use environment can be provided.

In one embodiment, the desiccant (not shown) may include silica gel particles, but is not limited to the above examples, and all desiccants that can be easily selected by a person skilled in the art of the present invention It should be construed as belonging to the scope of the present invention.

In one embodiment, the desiccant (not shown) may be disposed in the intake pipe 120, but is not limited to the above position, and may be disposed and used in the exhalation pipe 140 or the like.

Hereinafter, the oxygen supply unit 200 will be described.

It can be injected, and through this, it can be directly injected into the adsorbent 150 in the intake pipe 120.

In one embodiment, when gaseous oxygen flows into the main body 100 at too high a rate through the oxygen gas supply pipe 220, the adsorbent 150 may be excessively cooled, and conversely, gaseous oxygen When is introduced into the main body portion 100 at a too slow speed, the cooling effect may be weakened. In order to prevent this phenomenon, for example, the oxygen supply unit 200 may supply oxygen into the body unit 100 at a rate of 1.0 L/min to 3.0 L/min. As another example, the oxygen supplier 200 may supply oxygen at a rate of 1.5 L/min to 3.0 L/min, and as another example, oxygen may be supplied at a rate of 2.0 L/min to 3.0 L/min. .

When oxygen gas is injected into the main body 100 from the high-pressure oxygen container 210 as described above, the oxygen gas expands and its temperature decreases due to the pressure difference between the inside and outside of the high-pressure oxygen container 210. The inside of the main body 100 may be cooled using the low-temperature oxygen gas cooled as described above.

In one embodiment, the oxygen supplier 200 may cool a region inside the main body 100 by 0 to 10 ° C using low-temperature oxygen gas, and in another example, by 0 to 5 ° C. can make it By cooling one area inside the body part 100 by the temperature, the temperature of the intake air passing through the intake pipe 120 inside the body part 100 can be lowered, and through this, the user can use the ventilator for a longer period of time without discomfort. (10) can be used continuously.
