Description

  The present invention relates to a high-pressure oxygen supply apparatus including a chamber that accommodates a user, a pressurizing mechanism that pressurizes the chamber by sending gas into the chamber from a pressurization source, and a chamber used therefor. .

  The user is accommodated in a sealed chamber, air is fed into the chamber from a pressurizing pump, and the internal pressure of the chamber is made higher than the ambient pressure to raise the oxygen concentration and There is a high-pressure oxygen supply device that takes in a larger amount of oxygen than the amount of oxygen inhaled under the environment (see, for example, Patent Document 1).

  A user housed in a high-pressure oxygen supply device is exposed to a high-concentration oxygen environment to increase the oxygen concentration in the body. Oxygen taken into the body is divided into oxygen that binds to hemoglobin and oxygen that dissolves in blood and body fluids (lymph fluid, etc.). As the oxygen concentration in the body increases, the amount of oxygen dissolved in blood and body fluid increases. These oxygens can easily pass through the peripheral capillaries and carry oxygen to the cells. In order to supply oxygen to every corner of the body, oxygen dissolved in blood and body fluid is important.

  According to the high-pressure oxygen supply device, prompt recovery from fatigue can be expected by supplying sufficient oxygen into the body of the user. Moreover, since the peripheral blood circulation is improved, metabolic activity in the part where blood flow is inhibited becomes active, preventing coldness, relieving pain due to blood circulation disorder, and expecting quick recovery of the disorder.

  High-pressure oxygen supply equipment can be used, for example, by manual workers, athletes, smokers, those who work with liquid nitrogen / dry ice and paint, those who work in a polluted atmosphere, (Oxygen environment), people who work in closed places, elderly people, etc., and suitable for use when injured or after physical fatigue. It is also suitable for treating altitude sickness and carbon monoxide poisoning. That is, it is effective for those who need to quickly supply deficient oxygen, increase the number of active capillaries, or increase the blood volume. It can also be used in fields related to beauty and health.

  According to this, the expansion of the window plate due to the pressurization in the chamber can be suppressed, and the load on the bonding portion between the window portion and the window plate can be reduced. For this reason, it is possible to prevent fatigue destruction of the bonded portion between the window portion and the window plate, and as a result, it is possible to improve the reliability of the product.

  Moreover, it is preferable that the ring member formed cyclically | annularly with the flexible material is adhere | attached on the outer edge part of the window board and the reinforcement board in the aspect which covers the adhesion part of the said window board and the said reinforcement board. According to this, since the adhesion part of the window part 4 and the window board 5 will be in the state covered, the external appearance of the window part 4 seen from the inside of the chamber 1 can be improved. In addition, the expansion of the window plate can be further suppressed together with the reinforcing plate. Furthermore, since the airtightness of the bonded portion between the window plate and the reinforcing plate can be maintained, air can be prevented from entering between the window plate and the reinforcing plate.

  The reinforcing plate is preferably made of polycarbonate. According to this, the reinforcing plate can be made stronger while maintaining rigidity and also having an elastic property.

  Further, a small diameter hole may be formed in the window plate. According to this, even if air enters between the window plate and the reinforcing plate, the pressure of the air can be released from the small diameter hole.

  The exhaust valve 35 is connected to the chamber 1. It is used when the air in the chamber 1 is extracted, and the air sent from the chamber 1 is discharged to the outside.

  The pressurizing mechanism 9 is not limited to the above-described configuration, and any configuration may be used as long as air is fed into the chamber 1 to pressurize it.

  2A is a front view, FIG. 2B is a plan view, FIG. 2C is a rear view, and FIG. 2D is a side view.

  The chamber 1 is made of a flexible and non-breathable material such as EVA resin (Ethylene Vinylacetate copolymer). In addition to EVA resin, urethane, nylon, vinyl chloride, and the like can be given.

  The chamber 1 is provided with ports used for attaching an IN / OUT connection port for air, a connection port for a pressure sensor, a safety valve, and the like. A plurality of these ports are provided as tubes around the chamber 1 as shown in FIG.

  The upper surface 1a side of the chamber 1 is formed in a substantially cylindrical shape. As a result, a large space can be secured in the chamber 1 and the user can enter with sufficient margin. The chamber 1 is not limited to a substantially cylindrical shape, and may have other shapes.

  On the upper surface 1a side of the chamber 1, a fastener 2 is provided for a user to enter and exit. An airtight fastener is used as the fastener 2 in order to prevent air leakage in the chamber 1. In addition, the entrance / exit part of the chamber may have a double structure, and second and third fasteners may be provided to efficiently enhance the airtightness.

  A floor plate 3 is provided on the bottom surface 1 b side of the chamber 1. By providing the floor plate 3 in this manner, the bottom surface 1b side of the chamber 1 is flattened, the chamber 1 is stabilized, the chamber 1 is prevented from being overturned, and the user can lie down comfortably.

  On the side surface 1c side of the chamber 1, windows 4 each having a diameter of about 200 mm are formed at positions corresponding to the user's head.

  As shown in FIGS. 3 and 4, the window portion 4 is provided with a transparent or translucent window plate 5 made of a soft material such as vinyl chloride. The window plate is formed in a disk shape having a diameter of about 300 mm and a thickness of about 5 mm. The inner edge portion 4 a of the window portion 4 and the outer edge portion 5 a of the window plate 5 are bonded by heat welding or the like, and the window plate 5 is in a state of closing the window portion 4 from the inside of the chamber 1. This can reduce the user's sense of pressure and anxiety in the chamber, and contributes to safety because the user's state can be grasped from the outside.

  However, if only the window plate 5 made of a soft material is used, if the inside of the chamber 1 is pressurized, the window plate 5 also stretches each time. When the inside of the chamber 1 is repeatedly pressed every time it is used, a load is repeatedly applied to the bonded portion 7 of the window 4 and the window plate 5, and the bonded portion 7 is applied to the bonded portion 7 at an earlier stage than the limit of the bonding strength. Fatigue failure may occur due to cracks.

  Therefore, in the present invention, the transparent or translucent reinforcing plate 6 made of a hard material is provided on the surface inside the chamber of the window plate 5.

  The reinforcing plate 6 is formed in a thin disc shape having a diameter of 260 mm, which is smaller than the window plate 5 and larger than the window portion 4. The reinforcing plate 6 is arranged so that the center thereof coincides with the center of the window plate 5, and the outer edge portion 6 a is bonded to the outer edge portion 5 a of the window plate 5. That is, the window plate 5 and the reinforcing plate 6 are bonded to each other at a portion (bonded portion 8) corresponding to the bonded portion 7 between the window portion 4 and the window plate 5.

  According to this, the expansion of the window plate 5 due to the pressurization in the chamber 1 can be suppressed, and the load on the bonding portion 7 of the window plate 5 can be reduced. For this reason, it is possible to prevent fatigue failure of the bonded portion 7 of the window plate 5, and it is possible to improve the reliability of the product.

  More specifically, not only the reinforcing plate 6 made of a hard material is provided, but also the window plate 5 and the reinforcing plate 6 are bonded to each other in the portion corresponding to the bonding portion 7 of the window portion 4 and the window plate 5 (bonding portion 8). Therefore, the reinforcing plate 6 can suppress the entire extension from the outer edge portion 5 a of the window plate 5.

  Moreover, most of the fatigue failure of the window plate 5 occurs in the bonded portion 7 with the window portion 4, but the window plate 5 and the reinforcing plate 6 are further bonded at the portion corresponding to the bonded portion 7 (bonded portion 8). Therefore, the strength of the bonding portion 7 can be further improved.

  The reason why the reinforcing plate 6 is translucent or transparent is to maintain visibility in the window.

  Moreover, as a hard material of the reinforcement board 6, a polycarbonate is mentioned, for example. According to this, the reinforcing plate can be made stronger while maintaining rigidity and also having an elastic property.

  Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and various modifications can be made within the scope of the present invention described in the claims.

  For example, the window 4 is provided at the position corresponding to the user's head portion on the side of the chamber 1 to provide the window plate 5 with the reinforcing plate 6, but the window 4 is provided at other positions. A window plate 5 with a reinforcing plate 6 may be provided.

  In addition, the bonding portion between the window plate 5 and the reinforcing plate 6 is only the bonding portion 8 between the outer edge portion 5a of the window plate 5 and the outer edge portion 6a of the reinforcing plate 6, but the window plate 5 and the reinforcing plate 6 as a whole may be used. . However, in the former case, an adhesive or the like is not applied to the central portion of the window plate 5 or the reinforcing plate 6 and the visibility in the window portion 4 can be further ensured, which is more preferable.

  The reinforcing plate 6 has a smaller diameter than the window plate 5 and a larger diameter than the window portion 4, but is not limited thereto. However, since it is necessary to bond the window plate 5 and the reinforcing plate 6 at a portion (bonding portion 8) corresponding to the bonding portion 7 of the window portion 4 and the window plate 5, it is necessary to form at least a larger diameter than the window portion 4. There is.

[Embodiment 2]
A high-pressure oxygen supply apparatus (hereinafter referred to as this apparatus) according to another embodiment of the present invention will be described with reference to FIGS.

  In the present embodiment, a ring member 10 is provided on the surface inside the chamber of the reinforcing plate 6.

  The ring member 10 is made of a flexible material such as EVA and is formed in an annular shape. The ring member 10 has an outer diameter of 300 mm, which is the same as the outer diameter of the window plate 5, an inner diameter of 200 mm, which is the same as the diameter of the window portion 4, and a thickness of 1 mm.

  The ring member 10 has an outer edge portion 10a bonded to the outer edge portion 5a of the window plate 5 (bonding portion 11), and an inner edge portion 10b bonded to the outer edge portion 6a of the reinforcing plate 6 (adhesion). Part 12). As a result, the bonding portion 7 between the window portion 4 and the window plate 5 and the bonding portion 8 between the window plate 5 and the reinforcing plate 6 are covered, so that the appearance of the window portion 4 viewed from inside the chamber 1 can be improved. it can.

  Further, since the ring member 10 is bonded to the window plate 5 and the reinforcing plate 6, the expansion of the window plate 5 can be further suppressed in combination with the bonding of the window plate 5 and the reinforcing plate 6.

  Furthermore, since the airtightness of the bonding portion 8 between the window plate 5 and the reinforcing plate 6 can be maintained, air can be prevented from entering between the window plate 5 and the reinforcing plate 6. More specifically, the window plate 5 and the reinforcing plate 6 are bonded to each other at the peripheral edge (bonded portion 8) with an adhesive or the like. However, the window plate 5 and the reinforcing plate 6 may be bent or stretched depending on the material. Due to the difference, a gap may occur in the bonded portion 8 in some cases. For this reason, when air is sent into the chamber 1, air enters between the window plate 5 and the reinforcing plate 6 through a partial gap of the bonding portion 8, and the window plate 5 made of a soft material particularly bulges outward. There is. However, when the ring member 10 made of a flexible material is provided as described above, the outer edges of the window plate 5 and the reinforcing plate 6 are covered and airtightness can be maintained. Therefore, it is possible to prevent air from entering the inside.

  The size of the ring member 10 is not limited to the above. However, if the outer diameter is too large, it will protrude unnecessarily from the window plate 5, and if the inner diameter is too small, the window 4 will be blocked and the visibility will deteriorate, so the above-mentioned size is preferred.

  Further, the shape of the ring member 10 is not necessarily a circular ring shape, and may be other shapes depending on the shapes of the window plate 5 and the reinforcing plate 6.

  Further, a small diameter hole may be formed in the window plate 5. According to this, even if air enters between the window plate 5 and the reinforcing plate 6, the pressure of the air can be released from the small diameter hole.
