Description

Technical Field

[0001] The present invention relates to an oxygen-hydrogen bath system.Background Art(Positioning of the Present Application)

[0002] The applicant separately owns a patent (JP Patent No. 6133526, hereinafter referred to as Patent Document 1) entitled "Oxygen-Hydrogen Bath System." The present application is an application related to an improved invention of the invention described in said patent.

[0003] The invention covered by JP Patent No. 6133526 relates to an oxygen-hydrogen bath system that enables the body to absorb a greater amount of hydrogen than when ingesting hydrogen water orally, thereby making it easier to achieve the effect of reducing active oxygen species. However, in recent years, the elimination of excess active oxygen species from the body has been increasingly demanded for health maintenance. Those with such a need include busy businesspeople who are pressed for time. It is expected that such businesspeople could enjoy a significant advantage if they could take oxygen-hydrogen bathing in a short period of time, even during work hours. The fundamental technical concept of the invention described in the patent is to supply air, which has been brought to a certain hydrogen gas concentration outside the bath chamber, into an oxygen-hydrogen bath chamber at a constant speed and volume, while maintaining the hydrogen volume concentration of the air inside the chamber at a dynamic equilibrium.Citation ListPatent Literature

[0004] Patent Literature 1: Japanese Patent No. 6133526Disclosure of the InventionTechnical Problem

[0005] However, in the oxygen-hydrogen bath system implementing the invention described in Patent Document 1, the hydrogen gas generation capacity is limited to generating 500 cc of 100% hydrogen gas per minute due to safety concerns associated with using a hydrogen gas generator. Furthermore, the hydrogen concentration within the chamber can only be maintained up to 1.0 volume% once the dynamic equilibrium is reached. Therefore, there is an aspect where the system cannot sufficiently meet the market need for incorporating a sufficient amount of hydrogen into the body in a shorter period of time than this, or for incorporating a greater amount within the same period of time.

[0006] In such a case, a commonly considered solution is to simply increase the capacity of the hydrogen gas generator without changing the entire system. However, this solution is undesirable because the amount of hydrogen gas generated could exceed the safety-confirmed range, raising concerns about the risk of hydrogen explosions. Furthermore, it would necessitate the introduction of a new hydrogen gas generator, which significantly affects manufacturing costs, thereby leading to increased production expenses, which is undesirable from a business perspective.

[0007] Therefore, the inventor diligently researched a solution to achieve the objective while using the safety-verified hydrogen gas generator in which the amount of hydrogen gas generated has been confirmed to remain within the safe limits after the long-term use of the oxygen-hydrogen bath system described in Patent Document 1 (prior art), and while avoiding a significant increase in manufacturing costs. As a result of this earnest research, the inventor found that, without changing the hydrogen gas generator used in the oxygen-hydrogen bath system described in Patent Document 1, by merely inserting a simple, low-cost Y-joints into the air supply pipe of the system, routing one branch pipe in the same manner as Patent Document 1, and inserting a reducer into the other branch pipe, and connecting the outlet of the latter to the gas exhaust section of Patent Document 1 via a T-joint, the hydrogen concentration within the chamber of the oxygen-hydrogen bath system can be elevated and maintained at a level unattainable with the invention described in said document. Based on this finding, the present invention was made.Solution to Problem

[0009] The second invention is characterized in that, in the first invention, the valve maintains the pressure within the chamber at 1.1 to 1.35 atmospheric pressures and maintains the volume concentration of the hydrogen gas within the chamber at 1.0 to 2.0 volume percent.

[0010] The third invention is characterized in that, in the first or second invention, the hydrogen supply unit supplies the hydrogen gas into the chamber while the gas supply unit is supplying the air into the chamber.

[0011] Furthermore, the configuration of the invention described in Claim 1 of the present application adds the following underlined constituent elements to the configuration of the invention described in Claim 1 of Patent No. 6133526, which is already patented. Therefore, the added constituent elements are considered to possess sufficient patentability. The present invention is such that an oxygen-hydrogen bath system comprising: a chamber capable of accommodating the entire human body, having a gas supply port through which gas is introduced; a gas supply unit having an air supply pipe connected to the gas supply port, the gas supplying unit supplying an oxygen-containing air into the chamber via the air supply pipe to raise the pressure inside the chamber to above the atmospheric pressure; a hydrogen supply unit comprising a hydrogen supply pipe connected to the air supply pipe via an A-type Y-joint and a hydrogen gas generator, wherein the hydrogen supply unit supplies hydrogen gas from the hydrogen gas generator into the chamber via the hydrogen supply pipe; and a gas exhaust section connected to the chamber, having a valve that maintains the pressure inside the chamber within a predetermined pressure range via a safety valve or an ON / OFF operation, and discharges the air and the hydrogen gas from the chamber via the valve, wherein the air supply pipe of the gas supply unit has a B-type Y-joint positioned closer to the gas supply unit than the position of the A-type Y-joint, the B-type Y-joint dividing the flow path of the air from the gas supply unit into two equal parts, and wherein one branch pipe A extending from the B-type Y-joint is connected to the gas supply port after merging with the hydrogen supply pipe at the A-type Y-joint, and the other branch pipe B extends via a reducer and then connects to the gas exhaust section via a T-joint. Advantageous Effects of Invention

[0012] According to the present invention, it is expected that by using the safety-verified hydrogen gas generator in which the amount of hydrogen gas generated has been confirmed to remain within the safe limits after the long-term use of the oxygen-hydrogen bath system described in Patent Document 1 (prior art), and while making it easier to efficiently absorb a greater amount of hydrogen into the body through the human skin and mucous membranes in a shorter period of time than with conventional technologies, thereby more easily facilitating the achievement of the effect of reducing reactive oxygen species, but it is also expected that both oxygen gas and hydrogen gas can be absorbed into the human body in a greater amount as dissolved gases, thereby increasing the dissolved oxygen and dissolved hydrogen in the blood or body fluid.Brief Description of Drawings

[0014] Embodiments of the present invention will now be described with reference to the drawings.

[0015] The present invention is an improved invention of the prior art (the invention described in Patent Document 1), achieved by adding new constituent elements to the system configuration of the prior art. Therefore, to facilitate understanding of which components are newly added compared to the prior art system configuration, FIG. 1, showing a conceptual diagram of the prior art system configuration, and FIG. 2, showing a conceptual diagram of the system configuration of the present invention, are provided. The notation used in the system configuration conceptual diagram of FIG. 2 follows that used in the system configuration diagram of Patent Document 1, which represents the prior art. FIG. 3 provides a close-up view of the branching section, connection section, and the like shown in the system configuration diagram of FIG. 2.

[0016] The oxygen-hydrogen bath system 10 according to this embodiment comprises: a chamber 11 (not shown) for accommodating the entire human body; a gas supply unit 12 for supplying air into the chamber 11 to raise the internal pressure above the atmospheric pressure; a hydrogen supply unit 13 for supplying hydrogen gas into the chamber 11; a gas exhaust unit 15 for discharging air and hydrogen gas from the chamber 11; an A-type Y-joint 42 and a B-type Y-joint 44 located midway along the pipeline connecting the gas supply unit 12 and the chamber 11; a reducer 40 in the pipeline connecting the gas supply unit 12 and the gas exhaust unit 15; a T-joint 46 where the piping extending from the reducer 40 connects to the gas exhaust unit 15; a measurement unit 16 for measuring the environment inside the chamber; and a control unit 17 for controlling the environment inside the chamber.

[0017] As is evident from comparing FIG. 3, showing a conceptual diagram of the present invention's system, with FIG. 1, showing a conceptual diagram of the prior art system, in the present invention's system, an A-type Y-joint 42, a B-type Y-joint 44, a reducer 40, and a T-joint 46 are each positioned at the locations shown in FIG. 3. These components are connected by the piping shown as straight lines in FIG. 3, and this piping is made of the same material as the piping used in the prior art (the outer diameter and wall thickness of each pipe are described below).

[0018] Chamber 11 is composed of a cylindrical metal member, such as aluminum or stainless steel, and possesses air-tightness and moisture-impermeability, as well as strength sufficient to withstand the pressure of at least 1.4 atmospheric pressure. An opening 11a, large enough for a person to enter and exit, is provided on the side of chamber 11, along with an opening / closing member 18 that blocks the opening 11a. Furthermore, a gas supply port 20 connected to the gas supply unit 12 is provided on the side of the chamber 11.

[0019] The gas supply unit 12 includes a compressor 22 for introducing air (the oxygen-containing air) into chamber 11 at a pressure higher than the atmospheric pressure, and an air supply pipe (the air supply pipe) 23. The gas supply unit 12 may further include an air pressure regulating valve for adjusting the air's supply pressure. Alternatively, instead of the compressor 22, a pressure vessel (not shown) containing air pressurized to a pressure higher than the atmospheric pressure may be provided.

[0020] Here, the air (oxygen-containing air) compressed by the compressor 22 flows through the air supply pipe 23 toward the chamber 11. Interposed along its flow path are: a A-type Y-joint 44 for dividing the flow entering from one flow path into two equal flows exiting through two separate flow paths; and an B-type Y-joint 42 for merging the flow of hydrogen gas from the hydrogen supply unit 13 with the flow of compressed air from the compressor 22. The A-type Y-joint 44 has a standard Y-joint configuration, where the outer diameter and wall thickness of the inlet pipe are identical to those of the two outlet pipes. The A-type Y-joint 44 is inserted into the path of the air supply pipe 23 through which the air compressed by the compressor 22 flows. It evenly divides the volume of this compressed air into two equal halves, each flowing out into a branch pipe. Similarly, the B-type Y-joint 42 also has a typical Y-joint configuration. However, here it combines two flow paths with different outer diameters and wall thicknesses into a single flow path. Specifically, it is configured to combine air from one of the branch pipes branching off from the A-type Y-joint 44 with hydrogen gas from the hydrogen supply unit 13. The combined air-hydrogen mixture gas then flows as a single stream into the chamber 11 through the gas supply port 2 0.

[0021] The hydrogen supply unit 13 comprises a hydrogen gas generator 25 that generates hydrogen gas at a highconcentration by electrolysis of water, a hydrogen supply valve 26 positioned between the hydrogen gas generator 25 and the chamber 11, and a hydrogen supply pipe 27 connecting these components. This hydrogen supply pipe 27 converges at the B-type Y-joint with one branch pipe from the A-type Y-joint. Here, the hydrogen supply unit 13 may further include a hydrogen pressure regulating valve (not shown) to adjust the hydrogen gas supply pressure. The end of the hydrogen supply pipe 27 merges at the B-type Y-joint with a branch pipe from the air supply pipe's A-type Y-joint, which is located outside the chamber 11 at an intermediate position along the air supply pipe 23. Alternatively, instead of the hydrogen gas generator 25, a pressure vessel (not shown) pressurized with hydrogen gas at a pressure higher than the atmospheric pressure may be provided.

[0022] The gas exhaust unit 15 includes an exhaust valve 28 that discharges the air and hydrogen gas introduced into the chamber 11 to the outside of the chamber 11.

[0023] The gas exhaust unit 15 is operated ON / OFF by the control unit 17 to maintain the pressure inside the chamber 11 within a predetermined pressure range (i.e., above the atmospheric pressure and below the usable pressure of the exhaust valve 28) .

[0024] The gas exhaust unit 15 may further include a safety valve (not shown) that automatically exhausts the internal air when the pressure inside the chamber 11 reaches or exceeds a predetermined pressure.

[0025] The measurement unit 16 is connected to the control unit 17. The chamber 11 is connected to the control unit 17, and the measurement unit 16 includes a pressure sensor 30 that measures the pressure inside the chamber 11.

[0026] The control unit 17 is comprised of a computer including a CPU, memory, and display (not shown). It performs environmental control within the chamber 11 based on data from the pressure sensor 30. For example, it performs ON / OFF operations for the compressor 22, the hydrogen gas generator 25, and the hydrogen supply valve 26. It also performs ON / OFF operations for the exhaust valve 28 to adjust the pressure inside the chamber 11.

[0027] The entire system is controlled such that the environment within the chamber 11 is maintained that, when the pressure within the chamber 11 and the hydrogen volume concentration within the chamber 11 reach the dynamic equilibrium, the pressure within the chamber is preferably at 1.10 atmospheric pressure or higher and at 1.35 atmospheric pressure or lower, or at 1.10 atmospheric pressure or higher and below the usable pressure of the exhaust valve 28, and the oxygen volume concentration within chamber 11 is 20% or more but 30% or less, and the hydrogen volume concentration is less than the lower explosive limit of hydrogen and is 1.0% to 2.0%.

[0028] Here, the hydrogen supply unit 13 supplies hydrogen gas to the chamber 11 only while the gas supply unit 12 is supplying the air.

[0029] Note that the compressor 22, the hydrogen gas generator 25, and the hydrogen supply valve 26 may be configured for manual ON / OFF control, and the user may manually adjust various pressure controls while monitoring the various pressures displayed on the screen.

[0030] Next, the operation of the oxygen-hydrogen bath system 10 according to this embodiment will be described.

[0031] First, the user (not shown) enters the chamber 11 through the opening 11a after opening the chamber 11's opening / closing member 18.

[0032] After closing the opening / closing member 18, the entire system begins operation under the instructions from the control unit 17. Under the control unit 17's instructions, the gas supply unit 12 supplies air into the chamber 11, and the hydrogen supply unit 13 supplies hydrogen gas into the chamber 11.

[0033] At this time, the control unit 17 appropriately performs ON / OFF operation of the compressor 22 based on data from the measurement unit 16, the flow-control of the air and hydrogen gas via ON / OFF operation of the hydrogen gas generator 25 and the hydrogen supply valve 26, and the internal pressure control via ON / OFF operation of the exhaust valve 28.

[0034] This ensures the environment inside the chamber 11 (particularly the pressure and hydrogen volume concentration) reaches a dynamic equilibrium state within the desired time. Under this dynamic equilibrium state, the chamber 11 internal pressure is maintained at 1.10 atmospheric pressure or higher but not exceeding 1.35 atmospheric pressure, the oxygen volume concentration at 20% or higher but not exceeding 30%, and the hydrogen volume concentration preferably at 1.0% or higher but not exceeding 2.0%.

[0035] In the present invention, maintaining the environment within chamber 11 in a dynamic equilibrium state is one of the key points. The user (not shown) is exposed to this dynamically balanced environment within chamber 11 for a desired period of time. After this predetermined period of time has elapsed, the hydrogen supply unit 13 stops supplying hydrogen gas into the chamber 11, and subsequently, the gas supply unit 12 stops supplying the air into the chamber 11.

[0036] According to this oxygen-hydrogen bath system 10, as shown in FIG. 5 (prior art) and FIG. 6 (present invention), it becomes possible to raise the hydrogen volume concentration within chamber 11 to a higher value than the value achievable with the prior art, and in a shorter time. Furthermore, depending on the piping configuration within the system, it is possible to use the same hydrogen generator as used in the prior art, yet to achieve the final concentration value nearly double that of the prior art. This enables efficient intake into the human body within a short time.

[0037] Furthermore, by simultaneously increasing the oxygen concentration within the oxygen-containing air, the human body can be exposed to an atmosphere of high pressure and high oxygen concentration, where the oxygen concentration is elevated above the atmospheric pressure and exceeds the atmospheric oxygen concentration (approximately 21%). This allows for the incorporation of a greater amount of oxygen into the human body as dissolved oxygen.

[0038] Specifically, while the gas supply unit 12 supplies air into the chamber 11, the hydrogen supply unit 13 supplies the hydrogen gas into the chamber 11. This allows for suitably suppressing a state where the chamber 11 becomes hydrogenrich.

[0039] Furthermore, since it is possible to control the volume concentration of hydrogen gas within chamber 11 via the gas supply unit 12, the hydrogen supply unit 13, and the gas exhaust unit 15 such that it remains below the minimum value of the lower explosive limit of hydrogen gas, it is possible to suitably suppress the creation of a hazardous environment within chamber 11 where a hydrogen explosion could occur.(Example)

[0040] The graph showing the time variation of the hydrogen concentration within the chamber illustrated in FIG. 6 was obtained under the following conditions. Note that the pipe with an outer diameter φ10 mm had a wall thickness of 1.75 mm, the pipe with an outer diameter φ6 mm had a wall thickness of 1 mm, and the pipe with an outer diameter φ12 mm had a wall thickness of 2 mm. 1. The A-type Y-joint is configured for branching. 2. The outer diameter of the pipe connected to the inlet side of the B-type Y-joint is φ10 mm. The outer diameters of the two pipes connected to the outlet side of the A-type Y-joint are each φ10 mm. 3. The A-type Y-joint is configured for merging. Of the two pipes connected to the inlet side of the A-type Y-joint, the pipe for air (oxygen-containing air ) has an outer diameter of φ10 mm, and the pipe for hydrogen gas has an outer diameter of φ6 mm. The outer diameter of the single pipe connected to the outlet side of the A-type Y-joint is φ10 mm. 4. The reducer is a reducer that enlarges the inlet pipe with an outer diameter of φ10 mm to an outer diameter of φ12 mm. 5. The T-joint is configured to change the flow direction. The φ12 mm pipe extending from the reducer is connected to the φ12 mm exhaust line from the chamber. 6. The compressor operated at a discharge capacity of 200 liters per minute, and the hydrogen generator operated at a production capacity of 500 cc per minute} of 100% pure hydrogen gas at room temperature. 7. Under the above conditions, the hydrogen volume concentration at the outlet of the A-type Y-joint was approximately 3%. 8. Note that, in a conventional system equipped with the same B-type Y-joint but lacking the A-type Y-joint, reducer, and T-joint, the hydrogen volume concentration at the outlet of the B-type Y-joint was approximately 1% when using the same compressor and hydrogen generator.

[0041] The technical scope of the present invention is not limited to the above embodiments, and various modifications may be made without departing from the spirit of the invention. For example, while the gas supply unit 12 is described as supplying the air into the chamber 11, it is not limited to the air. Any gas that contains oxygen at a predetermined concentration and is safe for humans may be used instead of the air. Furthermore, there are no constraints on the spatial arrangement of the components. For instance, a configuration where the hydrogen gas supply port is positioned below the chamber also falls within the scope of the present invention.

[0042] Furthermore, the measurement unit 16 may be equipped with an oxygen concentration sensor and a hydrogen concentration sensor. In this case, the oxygen concentration and hydrogen concentration within the chamber 11 can be measured in real time.

[0043] Furthermore, while the hydrogen supply pipe 27 of the hydrogen supply unit 13 is described as being connected to the air supply pipe 23, the configuration is not limited to this. A separate hydrogen supply port may be provided in the chamber to supply hydrogen separately from air. In this case, the hydrogen supply pipe may extend from the hydrogen supply port to a location near the user's face when the user enters the chamber. This allows for more efficient hydrogen intake into the body.

[0044] The opening / closing member may also be a slide type. Furthermore, since the pressure inside the chamber 11 becomes greater than the atmospheric pressure during use, a structure where the slide operates on the inner surface side of the chamber is more preferable.Reference Signs List

[0005] However, in the oxygen-hydrogen bath system implementing the invention described in Patent Document 1, the hydrogen gas generation capacity is limited to generating 500 cc of 100% hydrogen gas per minute due to safety concerns associated with using a hydrogen gas generator. Furthermore, the hydrogen concentration within the chamber can only be maintained up to 1.0 volume% once the dynamic equilibrium is reached. Therefore, there is an aspect where the system cannot sufficiently meet the market need for incorporating a sufficient amount of hydrogen into the body in a shorter period of time than this, or for incorporating a greater amount within the same period of time.

Based on this finding, the present invention was made.Solution to Problem

[0008] That is, the first invention is an oxygen-hydrogen bath system comprising: a chamber capable of accommodating the entire human body, having a gas supply port through which gas is introduced; a gas supply unit having an air supply pipe connected to the gas supply port, the gas supplying unit supplying an oxygen-containing air into the chamber via the air supply pipe to raise the pressure inside the chamber to above the atmospheric pressure; a hydrogen supply unit comprising a hydrogen supply pipe connected to the air supply pipe via an A-type Y-joint and a hydrogen gas generator, wherein the hydrogen supply unit supplies hydrogen gas from the hydrogen gas generator into the chamber via the hydrogen supply pipe; and a gas exhaust section connected to the chamber, having a valve that maintains the pressure inside the chamber within a predetermined pressure range via a safety valve or an ON / OFF operation, and discharges the air and the hydrogen gas from the chamber via the valve, wherein the air supply pipe of the gas supply unit has a B-type Y-joint positioned closer to the gas supply unit than the position of the A-type Y-joint, the B-type Y-joint dividing the flow path of the air from the gas supply unit into two equal parts, and wherein one branch pipe A of the B-type Y-joint is connected to the gas supply port after merging with the hydrogen supply pipe at the A-type Y-joint, and the other branch pipe B extends via a reducer and then connects to the gas exhaust section via a T-joint.

[0009] The second invention is characterized in that, in the first invention, the valve maintains the pressure within the chamber at 1.1 to 1.35 atmospheric pressures and maintains the volume concentration of the hydrogen gas within the chamber at 1.0 to 2.0 volume percent.

Advantageous Effects of Invention

[0014] Embodiments of the present invention will now be described with reference to the drawings.

[0015] The present invention is an improved invention of the prior art (the invention described in Patent Document 1), achieved by adding new constituent elements to the system configuration of the prior art. Therefore, to facilitate understanding of which components are newly added compared to the prior art system configuration, FIG. 1, showing a conceptual diagram of the prior art system configuration, and FIG. 2, showing a conceptual diagram of the system configuration of the present invention, are provided. The notation used in the system configuration conceptual diagram of FIG. 2 follows that used in the system configuration diagram of Patent Document 1, which represents the prior art. FIG. 3 provides a close-up view of the branching section, connection section, and the like shown in the system configuration diagram of FIG. 2.

[0016] The oxygen-hydrogen bath system 10 according to this embodiment comprises: a chamber 11 (not shown) for accommodating the entire human body; a gas supply unit 12 for supplying air into the chamber 11 to raise the internal pressure above the atmospheric pressure; a hydrogen supply unit 13 for supplying hydrogen gas into the chamber 11; a gas exhaust unit 15 for discharging air and hydrogen gas from the chamber 11; an A-type Y-joint 42 and a B-type Y-joint 44 located midway along the pipeline connecting the gas supply unit 12 and the chamber 11; a reducer 40 in the pipeline connecting the gas supply unit 12 and the gas exhaust unit 15; a T-joint 46 where the piping extending from the reducer 40 connects to the gas exhaust unit 15; a measurement unit 16 for measuring the environment inside the chamber; and a control unit 17 for controlling the environment inside the chamber.

[0017] As is evident from comparing FIG. 3, showing a conceptual diagram of the present invention's system, with FIG. 1, showing a conceptual diagram of the prior art system, in the present invention's system, an A-type Y-joint 42, a B-type Y-joint 44, a reducer 40, and a T-joint 46 are each positioned at the locations shown in FIG. 3. These components are connected by the piping shown as straight lines in FIG. 3, and this piping is made of the same material as the piping used in the prior art (the outer diameter and wall thickness of each pipe are described below).

[0018] Chamber 11 is composed of a cylindrical metal member, such as aluminum or stainless steel, and possesses air-tightness and moisture-impermeability, as well as strength sufficient to withstand the pressure of at least 1.4 atmospheric pressure. An opening 11a, large enough for a person to enter and exit, is provided on the side of chamber 11, along with an opening / closing member 18 that blocks the opening 11a. Furthermore, a gas supply port 20 connected to the gas supply unit 12 is provided on the side of the chamber 11.

[0019] The gas supply unit 12 includes a compressor 22 for introducing air (the oxygen-containing air) into chamber 11 at a pressure higher than the atmospheric pressure, and an air supply pipe (the air supply pipe) 23. The gas supply unit 12 may further include an air pressure regulating valve for adjusting the air's supply pressure. Alternatively, instead of the compressor 22, a pressure vessel (not shown) containing air pressurized to a pressure higher than the atmospheric pressure may be provided.

[0020] Here, the air (oxygen-containing air) compressed by the compressor 22 flows through the air supply pipe 23 toward the chamber 11. Interposed along its flow path are: a A-type Y-joint 44 for dividing the flow entering from one flow path into two equal flows exiting through two separate flow paths; and an B-type Y-joint 42 for merging the flow of hydrogen gas from the hydrogen supply unit 13 with the flow of compressed air from the compressor 22. The A-type Y-joint 44 has a standard Y-joint configuration, where the outer diameter and wall thickness of the inlet pipe are identical to those of the two outlet pipes. The A-type Y-joint 44 is inserted into the path of the air supply pipe 23 through which the air compressed by the compressor 22 flows. It evenly divides the volume of this compressed air into two equal halves, each flowing out into a branch pipe. Similarly, the B-type Y-joint 42 also has a typical Y-joint configuration. However, here it combines two flow paths with different outer diameters and wall thicknesses into a single flow path. Specifically, it is configured to combine air from one of the branch pipes branching off from the A-type Y-joint 44 with hydrogen gas from the hydrogen supply unit 13. The combined air-hydrogen mixture gas then flows as a single stream into the chamber 11 through the gas supply port 2 0.

[0021] The hydrogen supply unit 13 comprises a hydrogen gas generator 25 that generates hydrogen gas at a highconcentration by electrolysis of water, a hydrogen supply valve 26 positioned between the hydrogen gas generator 25 and the chamber 11, and a hydrogen supply pipe 27 connecting these components. This hydrogen supply pipe 27 converges at the B-type Y-joint with one branch pipe from the A-type Y-joint. Here, the hydrogen supply unit 13 may further include a hydrogen pressure regulating valve (not shown) to adjust the hydrogen gas supply pressure. The end of the hydrogen supply pipe 27 merges at the B-type Y-joint with a branch pipe from the air supply pipe's A-type Y-joint, which is located outside the chamber 11 at an intermediate position along the air supply pipe 23. Alternatively, instead of the hydrogen gas generator 25, a pressure vessel (not shown) pressurized with hydrogen gas at a pressure higher than the atmospheric pressure may be provided.

[0022] The gas exhaust unit 15 includes an exhaust valve 28 that discharges the air and hydrogen gas introduced into the chamber 11 to the outside of the chamber 11.

[0023] The gas exhaust unit 15 is operated ON / OFF by the control unit 17 to maintain the pressure inside the chamber 11 within a predetermined pressure range (i.e., above the atmospheric pressure and below the usable pressure of the exhaust valve 28) .

[0024] The gas exhaust unit 15 may further include a safety valve (not shown) that automatically exhausts the internal air when the pressure inside the chamber 11 reaches or exceeds a predetermined pressure.

[0025] The measurement unit 16 is connected to the control unit 17. The chamber 11 is connected to the control unit 17, and the measurement unit 16 includes a pressure sensor 30 that measures the pressure inside the chamber 11.

[0026] The control unit 17 is comprised of a computer including a CPU, memory, and display (not shown). It performs environmental control within the chamber 11 based on data from the pressure sensor 30. For example, it performs ON / OFF operations for the compressor 22, the hydrogen gas generator 25, and the hydrogen supply valve 26. It also performs ON / OFF operations for the exhaust valve 28 to adjust the pressure inside the chamber 11.

[0027] The entire system is controlled such that the environment within the chamber 11 is maintained that, when the pressure within the chamber 11 and the hydrogen volume concentration within the chamber 11 reach the dynamic equilibrium, the pressure within the chamber is preferably at 1.10 atmospheric pressure or higher and at 1.35 atmospheric pressure or lower, or at 1.10 atmospheric pressure or higher and below the usable pressure of the exhaust valve 28, and the oxygen volume concentration within chamber 11 is 20% or more but 30% or less, and the hydrogen volume concentration is less than the lower explosive limit of hydrogen and is 1.0% to 2.0%.

[0028] Here, the hydrogen supply unit 13 supplies hydrogen gas to the chamber 11 only while the gas supply unit 12 is supplying the air.

[0029] Note that the compressor 22, the hydrogen gas generator 25, and the hydrogen supply valve 26 may be configured for manual ON / OFF control, and the user may manually adjust various pressure controls while monitoring the various pressures displayed on the screen.

[0030] Next, the operation of the oxygen-hydrogen bath system 10 according to this embodiment will be described.

[0031] First, the user (not shown) enters the chamber 11 through the opening 11a after opening the chamber 11's opening / closing member 18.

[0032] After closing the opening / closing member 18, the entire system begins operation under the instructions from the control unit 17. Under the control unit 17's instructions, the gas supply unit 12 supplies air into the chamber 11, and the hydrogen supply unit 13 supplies hydrogen gas into the chamber 11.

[0033] At this time, the control unit 17 appropriately performs ON / OFF operation of the compressor 22 based on data from the measurement unit 16, the flow-control of the air and hydrogen gas via ON / OFF operation of the hydrogen gas generator 25 and the hydrogen supply valve 26, and the internal pressure control via ON / OFF operation of the exhaust valve 28.

[0034] This ensures the environment inside the chamber 11 (particularly the pressure and hydrogen volume concentration) reaches a dynamic equilibrium state within the desired time. Under this dynamic equilibrium state, the chamber 11 internal pressure is maintained at 1.10 atmospheric pressure or higher but not exceeding 1.35 atmospheric pressure, the oxygen volume concentration at 20% or higher but not exceeding 30%, and the hydrogen volume concentration preferably at 1.0% or higher but not exceeding 2.0%.

[0035] In the present invention, maintaining the environment within chamber 11 in a dynamic equilibrium state is one of the key points. The user (not shown) is exposed to this dynamically balanced environment within chamber 11 for a desired period of time. After this predetermined period of time has elapsed, the hydrogen supply unit 13 stops supplying hydrogen gas into the chamber 11, and subsequently, the gas supply unit 12 stops supplying the air into the chamber 11.

[0036] According to this oxygen-hydrogen bath system 10, as shown in FIG. 5 (prior art) and FIG. 6 (present invention), it becomes possible to raise the hydrogen volume concentration within chamber 11 to a higher value than the value achievable with the prior art, and in a shorter time. Furthermore, depending on the piping configuration within the system, it is possible to use the same hydrogen generator as used in the prior art, yet to achieve the final concentration value nearly double that of the prior art. This enables efficient intake into the human body within a short time.

[0037] Furthermore, by simultaneously increasing the oxygen concentration within the oxygen-containing air, the human body can be exposed to an atmosphere of high pressure and high oxygen concentration, where the oxygen concentration is elevated above the atmospheric pressure and exceeds the atmospheric oxygen concentration (approximately 21%). This allows for the incorporation of a greater amount of oxygen into the human body as dissolved oxygen.

[0038] Specifically, while the gas supply unit 12 supplies air into the chamber 11, the hydrogen supply unit 13 supplies the hydrogen gas into the chamber 11. This allows for suitably suppressing a state where the chamber 11 becomes hydrogenrich.

[0039] Furthermore, since it is possible to control the volume concentration of hydrogen gas within chamber 11 via the gas supply unit 12, the hydrogen supply unit 13, and the gas exhaust unit 15 such that it remains below the minimum value of the lower explosive limit of hydrogen gas, it is possible to suitably suppress the creation of a hazardous environment within chamber 11 where a hydrogen explosion could occur.(Example)

[0040] The graph showing the time variation of the hydrogen concentration within the chamber illustrated in FIG. 6 was obtained under the following conditions. Note that the pipe with an outer diameter φ10 mm had a wall thickness of 1.75 mm, the pipe with an outer diameter φ6 mm had a wall thickness of 1 mm, and the pipe with an outer diameter φ12 mm had a wall thickness of 2 mm. 1. The A-type Y-joint is configured for branching. 2. The outer diameter of the pipe connected to the inlet side of the B-type Y-joint is φ10 mm. The outer diameters of the two pipes connected to the outlet side of the A-type Y-joint are each φ10 mm. 3. The A-type Y-joint is configured for merging. Of the two pipes connected to the inlet side of the A-type Y-joint, the pipe for air (oxygen-containing air ) has an outer diameter of φ10 mm, and the pipe for hydrogen gas has an outer diameter of φ6 mm. The outer diameter of the single pipe connected to the outlet side of the A-type Y-joint is φ10 mm. 4. The reducer is a reducer that enlarges the inlet pipe with an outer diameter of φ10 mm to an outer diameter of φ12 mm. 5. The T-joint is configured to change the flow direction. The φ12 mm pipe extending from the reducer is connected to the φ12 mm exhaust line from the chamber. 6. The compressor operated at a discharge capacity of 200 liters per minute, and the hydrogen generator operated at a production capacity of 500 cc per minute} of 100% pure hydrogen gas at room temperature. 7. Under the above conditions, the hydrogen volume concentration at the outlet of the A-type Y-joint was approximately 3%. 8. Note that, in a conventional system equipped with the same B-type Y-joint but lacking the A-type Y-joint, reducer, and T-joint, the hydrogen volume concentration at the outlet of the B-type Y-joint was approximately 1% when using the same compressor and hydrogen generator.

[0041] The technical scope of the present invention is not limited to the above embodiments, and various modifications may be made without departing from the spirit of the invention. For example, while the gas supply unit 12 is described as supplying the air into the chamber 11, it is not limited to the air. Any gas that contains oxygen at a predetermined concentration and is safe for humans may be used instead of the air. Furthermore, there are no constraints on the spatial arrangement of the components. For instance, a configuration where the hydrogen gas supply port is positioned below the chamber also falls within the scope of the present invention.

[0042] Furthermore, the measurement unit 16 may be equipped with an oxygen concentration sensor and a hydrogen concentration sensor. In this case, the oxygen concentration and hydrogen concentration within the chamber 11 can be measured in real time.

[0043] Furthermore, while the hydrogen supply pipe 27 of the hydrogen supply unit 13 is described as being connected to the air supply pipe 23, the configuration is not limited to this. A separate hydrogen supply port may be provided in the chamber to supply hydrogen separately from air. In this case, the hydrogen supply pipe may extend from the hydrogen supply port to a location near the user's face when the user enters the chamber. This allows for more efficient hydrogen intake into the body.

[0044] The opening / closing member may also be a slide type. Furthermore, since the pressure inside the chamber 11 becomes greater than the atmospheric pressure during use, a structure where the slide operates on the inner surface side of the chamber is more preferable.Reference Signs List
