Accordingly, the present inventors filed a respiratory gas storage device on June 24, 1991, which can obtain low-oxygen air at a low cost with a simple configuration, and filed a patent application on June 5, 1995. Notice (Jitsuhei 7-24110, Registration No. 2,115,
446).

[0006] In this configuration, a respiratory gas storage tank having a mask having a penetrating portion and applied to a respiratory port, and a closed space connected to the mask and communicating with the respiratory port side of the mask via the penetrating portion. And Then, it is preferable to arrange a carbon dioxide absorbent for absorbing carbon dioxide in the closed section or in a portion communicating with the closed section, and further, an intake pipe and / or an exhaust pipe each having a check member are inserted in the closed section. Also disclosed is a configuration in which the mask communicates with the closed space.

[0007] According to such a configuration, when the mask is applied to, for example, a person's breathing port and is breathed by the air in the breathing gas storage tank, the oxygen concentration in the breathing gas storage tank is reduced by this breathing, which is preferable for health. 20% to 10%
A degree of low oxygen air is easily and automatically created under normal pressure.

In the configuration in which the carbon dioxide absorbent is disposed in a breathing gas storage tank or the like, the carbon dioxide flowing into the closed space by respiration is absorbed by the carbon dioxide absorbent, and the rising tempo is reduced. In the configuration in which the intake pipe and / or the exhaust pipe each having a check member are inserted into the closed space, the breathing gas from the breathing port mixes quickly with the remaining gas in the closed space.

[0009]

However, in the respiratory gas storage device disclosed by the present inventor, if the internal volume of the respiratory gas storage tank is set to about 5 liters, for example, the oxygen concentration due to respiration at rest will be as shown in FIG. As shown, it decreases to 10% or less in about 2-3 minutes, and is considered to be favorable for health.
In order to maintain a low oxygen air condition of about 10% for a long time, further improvement has been desired.

[0010] As described above, if the carbon dioxide absorbent is disposed in the breathing gas storage tank or the like, the rising tempo of the concentration of carbon dioxide flowing in by respiration can be slowed, but the carbon dioxide absorbent increases carbon dioxide. Just keeping the amount small will not be an effective means of maintaining a favorable hypoxic state of about 15 to 10% for a long time.

The present invention has been made under such circumstances, and it is an object of the present invention to provide a respiratory gas storage device which can obtain a relatively long and favorable low oxygen air state under normal pressure with an inexpensive and simple structure. .

[0012]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a mask made of an airtight material having a penetrating portion and applied to a breathing opening, and a mask which is directly or indirectly connected to the mask. A respiratory gas storage unit having a closed space communicated with the respiratory port side of the mask through the penetrating part, and an external air supply hole through which external air is circulated and supplied by respiration from the airtight material mask to the respiratory gas storage unit. It is provided between them.

[0015]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a sectional view showing an embodiment of a breathing gas storage device according to the present invention. In FIG. 1, a mask 1 is formed from a flexible airtight material such as a synthetic resin such as natural rubber, vinyl chloride resin or polyurethane resin into a shallow bowl with a wide mouth, and can be applied at least to a human mouth. It has a shape, and has a through hole 3 in the center thereof. Note that a shape that covers the mouth and nose at once and can be airtight is preferable.

One end 5a of a communication tube (part) 5 formed in a cylindrical shape from, for example, a synthetic resin or a metal material is inserted and connected to the through hole 3 of the mask 1 by, for example, being screwed.

The communication pipe 5 is bent in an L shape, and the other end 5b is connected to a breathing gas storage unit 7.

The breathing gas storage section 7 forms a closed space for storing breathing gas, and is, for example, a balloon of about 4 liters made of synthetic rubber, natural rubber or paper. Of the other end 5b so as not to come off easily.

In such a configuration, a feature of the present invention is that even when the mask 1 covers the mouth and nose at a time so that they can be air-tight, the outside air supply hole 9 through which outside air can flow.
Is that one or a plurality of masks are formed through the mask 1.

The outside air supply hole 9 has a function of circulating outside air by covering the mouth and nose at once with the mask 1 and breathing. That is, during inspiration, outside air flows into and replenishes the inside of the mask 1, and during exhaustion, gas from the mouth and nose partially flows out to the outside. .

Next, an example of use of such a breathing gas storage device of the present invention will be described. When the respiratory gas storage unit 7 is filled with outside air and the mask 1 is covered with the respiratory port of a person so as to cover the mouth and nose and breathed, the outside air supply hole 9 together with the gas in the respiratory gas storage unit 7 during inhalation. A small amount of outside air is taken in from the mouth and nose, and at the time of exhaustion, gas with reduced oxygen from the mouth and nose mainly enters the respiratory gas storage unit 7 and a small amount of exhaust air passes through the outside air supply hole 9. Spilled out.

Even if the outside air is supplied through the outside air supply hole 9 at the time of intake, if the inside diameter of the outside air supply hole 9 is appropriately selected, the oxygen concentration of the gas discharged from the mouth and nose at the time of exhaustion can be reduced. The concentration gradually decreases, and the oxygen concentration in the breathing gas storage unit 7 gradually decreases as the breathing progresses.

As described above, in the respiratory gas storage device of the present invention, it is important to select the inner diameter of the outside air supply hole 9, and the amount of oxygen consumed by an adult male during resting breathing in the body tissue is 250 ml / min. About 1000 inhalation volume
Since the flow rate is ml / min, the inner diameter of the outside air supply hole 9 is selected so that a smaller amount of oxygen is taken in.

However, if the inside diameter of the outside air supply hole 9 is selected to be large, it is difficult to quickly obtain a low oxygen state, and if it is too small, it is difficult to maintain the low oxygen state for a long time.

Although it depends on the surface area (volume) of the breathing gas storage part 7 and the like, according to the experiment of the present inventor, for example, three hours after the start of use.
It realizes 18% intake hypoxia in about a minute,
% In order to maintain the inhalation hypoxia state of about 180 minutes, the inside diameter, area, or area of the outside air supply hole 9 is set to about the container having the combined surface area of the mask 1, the communication pipe 5, and the respiratory gas storage unit 7. It is preferable to select 1/400 to 1/700.

FIG. 6 shows the oxygen concentration reduction characteristics when the combined surface area of the mask 1, the communication pipe 5 and the breathing gas storage part 7 is 2489.12 cm ² and the inside diameter of the outside air supply hole 9 is 4.396 cm ^2. It is a figure, and according to a figure, 15-16
% Can be maintained for as long as about 180 minutes.

As described above, in the respiratory gas storage device of the present invention, the penetrating portion 3 is formed in the mask 1 made of an airtight material to be applied to the respiratory port, and the communicating tube 5 is connected to the penetrating portion 3 of the mask 1. In addition to connecting the respiratory gas storage unit 7 to the air outlet 5 and forming an external air supply hole 9 through which air is supplied by respiration through the mask 1, a low oxygen state can be obtained easily and quickly, and the low oxygen state can be relatively reduced. There is an advantage that it can be maintained for a long time.

By breathing this low oxygen, glycolysis, which is a metabolism that anaerobically decomposes sugar to obtain energy, can be stimulated to improve the body's resistance.

The mechanism in the body can be represented by the following chemical formula. 1 / n (C ₆ H ₁₀ O ₅ ) n + 3ADP + 3H ₃ PO ₄ →
2C ₃ H ₆ O ₃ +3 ATP

Therefore, medical effects can be expected by breathing low oxygen air even for a short period of time. For example, autonomic imbalance, various allergic skin diseases,
It is effective in preventing respiratory diseases, cardiovascular diseases, habitual miscarriage, etc. and promoting treatment.

In particular, in the breathing gas storage device of the present invention, the inner diameter of the outside air supply hole 9 is changed from the mask 1 to the breathing gas storage portion 7.
If the surface area is selected to be 1/400 to 1/700, a low oxygen state of about 20 to 10% can be maintained for about 180 minutes as shown in FIG.

In the present invention, the number of outside air supply holes 9 is arbitrary, and a plurality of outside air supply holes 9 can be formed. In the configuration in which a plurality of outside air supply holes 9 are formed, the total inner diameter or area is 1/400 to 1/700 of the surface area from the mask 1 to the breathing gas storage unit 7 as described above.
It is good that it is selected to the extent. Here, it goes without saying that the total surface area includes the mask 1 and the breathing gas storage unit 7.

Further, as shown in FIGS. 2 and 3, for example, a plurality of outside air supply holes 9 are formed in the mask 1 in an arc shape at predetermined intervals, and a fan-shaped A configuration is also possible in which the closing member 11 is rotatably fixed with a screw 13 or the like, and an arbitrary number of the plurality of outside air supply holes 9 is closed by rotating and sliding the closing member 11.

In this manner, in a configuration in which any of the plurality of outside air supply holes 9 is closed, the amount of outside air supply can be adjusted by changing the number of the outside air supply holes 9 to be closed. Various adaptations can be made according to the usage pattern of.

The breathing gas storage section 7 is not limited to a flexible balloon such as rubber or paper, but may be a closed tank made of a synthetic resin, a metal material, or the like. further,
The position at which the outside air supply hole 9 is formed is not limited to the mask 1 but may be the communication pipe 5.
And / or the respiratory gas storage 7 may be the mask 1
It is only necessary that it be formed between the respiratory gas storage part 7 and.

In the configuration in which the outside air supply hole 9 is formed in the breathing gas storage section 7, the breathing gas storage section 7 does not form a strictly closed space. Has internal dimensions that do not occur very much,
What is necessary is just to function practically as a closed space.

However, when the breathing gas storage part 7 is formed by a rubber balloon, it is not preferable in terms of its function to form the outside air supply hole 9 therein. Further, the structure of the variable closing member 11 for selectively closing the plurality of outside air supply holes 7 may be a conventionally known configuration, and is arbitrary.

Next, another embodiment of the breathing gas storage device according to the present invention will be described. FIG. 4 shows a configuration in which a holding cylinder 15 is connected and interposed between the communication pipe 5 and the breathing gas storage unit 7 in the configuration of FIG.

The holding cylinder 15 is formed of a synthetic resin, hard glass or a metal material into a cylindrical shape having a large inner diameter, and both ends 15a and 15b are thin, and one end 15a thereof is formed.
Is inserted and connected by being screwed into the communication pipe 5, while the suction and discharge port 7 a of the breathing gas storage unit 7 is provided on the outer periphery of the other end 15 b.
Is crimped so as to be covered.

In the holding cylinder 15, both ends 15a, 15a
Except in the vicinity of b, a porous carbon dioxide absorbing layer (portion) 17 to which a carbon dioxide absorbent made of soda lime or the like that absorbs carbon dioxide is attached and held so as to fill the inside.

In the vicinity of one end 15a in the holding cylinder 15,
A coarse mesh filter 19 is disposed so as to cross the axis of the holding cylinder 15. The filter 19 is for preventing dust and the like from the carbon dioxide absorbing layer 17 from being sucked during breathing. Although not shown, the holding cylinder 15
Is split in the axial direction so that the carbon dioxide absorption layer (part) 17 and the filter 19 are replaceable, and are integrated into a cylindrical shape by fitting or screwing.

The holding cylinder 15 has both ends 15a, 15b
A plurality of outside air supply holes 9 are formed in the vicinity where the carbon dioxide absorption layer 17 is not disposed.

In the respiratory gas storage device according to FIG. 4 as well, when the respiratory gas storage unit 7 is filled with outside air and the mask 1 covers the mouth and nose and is applied to the respiratory port of a person to breathe, Sometimes, the gas in the breathing gas storage unit 7 is
Through the communication pipe 5 and the mask 1 through the mouth and nose, and a little outside air through the outside air supply hole 9 is also taken in from the mouth and nose.

On the other hand, at the time of exhaust, the gas with reduced oxygen from the mouth and nose enters mainly into the breathing gas storage unit 7 through the holding cylinder 15, and a small amount of exhaust goes to the outside through the outside air supply hole 9. Will be leaked.

Even when the outside air is supplied through the outside air supply hole 9 at the time of inhalation, if the inside diameter of the outside air supply hole 9 is appropriately selected, the oxygen concentration of the gas discharged from the mouth and nose at the time of exhaustion can be reduced. The concentration gradually decreases, and the oxygen concentration in the breathing gas storage unit 7 gradually decreases as the breathing progresses.

Further, each time gas from the respiratory gas storage unit 7 or gas to the respiratory gas storage unit 7 passes through the holding cylinder 15 due to respiration, the carbon dioxide absorption layer 1 disposed inside
7, the absorption of carbon dioxide is absorbed, and the increase in carbon dioxide accompanying respiration is greatly suppressed.

In the breathing gas storage device having such a configuration,
Since the communication pipe 5 and the respiratory gas storage unit 7 are connected via the holding cylinder 15 holding the carbon dioxide absorption layer 17 therein, the low oxygen air state can be easily changed under normal pressure by respiration, similarly to the configuration of FIG. It is possible to maintain a low oxygen state for a relatively long time and to delay the increase in the amount of carbon dioxide accumulated as a gas. It becomes difficult to form a carbon state, and it is possible to avoid any trouble due to an increase in the concentration of carbon dioxide.

Then, in the configuration shown in FIG.
1/400 with respect to the surface area from
Needless to say, it is preferable to set the total inner diameter of the outside air supply holes 9 within a range of about 1/700.
The shape, the number, and the formation position are arbitrary, and it is also possible to provide a closing member for selectively closing these.

By the way, since the carbon dioxide absorbent is also provided with an absorbent that changes its color according to the amount of absorption, this type of carbon dioxide absorbent is used for the carbon dioxide absorbing layer 17 and the entire holding cylinder 15 or If a part is formed of a transparent material, there is an advantage that the use limit of the carbon dioxide absorption layer 17 can be confirmed by its discoloration.

The carbon dioxide absorbing layer 17 is
The communication pipe 5 and the breathing gas storage unit 7
May be arranged between them. Further, in the present invention, the mask 1
The communication pipe 5 can be omitted by directly connecting the breathing gas storage section 7 to the storage section.

In the respiratory gas storage device of the present invention, when a humidifier is connected to the communication tube 5, it becomes possible to give wetness to the throat during breathing. There is an advantage that the atmosphere can be obtained.
However, it is also possible to provide a dehumidifier instead of a humidifier.
