[0004] [Patent Document 1] Patent No. 7156965 Summary of the Invention [Problem to be solved by the invention]

[0005] Conventional training rooms have room for improvement in terms of optimizing the arrangement and functions of components constituting the hypoxic space, such as oxygen concentration sensors, carbon dioxide concentration sensors, ventilation openings, hypoxic air supply openings, training machines, etc. For example, further improvements are desired in terms of ensuring the accuracy and fail-safety of the positional relationship with the user in measuring oxygen concentration and carbon dioxide concentration, and maintaining an appropriate air environment in the training room.

[0011] [First embodiment] (overview) In this embodiment, a hypoxic training facility for training in a hypoxic state will be described. The hypoxic training facility described in this embodiment is a facility where efficient training can be carried out in a hypoxic room having an environment simulating high altitude by creating a hypoxic state. Hypoxic air with a low oxygen concentration is supplied from outside the hypoxic room, so that a user in the hypoxic room can train in a hypoxic state. The oxygen concentration is constantly monitored to prevent hypoxemia. By optimizing the position of the monitoring device, the position of the exhaust port for exhausting air in the hypoxic room, etc., health accidents caused by a hypoxic state can be prevented in advance, and the user can safely perform simulated high altitude training.

[0012] (Overall composition) <100 Low Oxygen Training Facilities> FIG. 1 is a schematic diagram showing the configuration of a hypoxic training facility 100 according to this embodiment. The hypoxic training facility 100 includes an information processing device 1, a hypoxic room 2, a machine room 3, and a control room 4. The hypoxic room 2 and the machine room 3 are provided separately and are separated by a wall. The configuration of the wall is not particularly limited, and the hypoxic room 2 and the machine room 3 do not have to be separated by a wall.

[0013] <Information processing device 1> The information processing device 1 controls each device in the hypoxic training facility 100. The information processing device 1 is not limited to being installed in the control room 4, and may be installed in, for example, the machine room 3. Details of the control in the information processing device 1 will be described later.

[0014] <Low oxygen room 2> The low-oxygen room 2 provides a space with a low oxygen concentration for performing exercise-related training. In this embodiment, the positional relationship between objects is defined by the points that are the shortest distance apart, unless otherwise specified. For example, the distance between a first object and a second object is the shortest distance between the first object and the second object. The height of the first object from the floor indicates the height of the shortest distance between the first object and the floor. Similarly, the height of the opening from the floor indicates the height of the shortest distance between the opening and the floor. In addition, as for the entrance and exit doors and windows, since they are relatively large, their geometric center points are exceptionally used. The geometric center is the position of the arithmetic mean of all points belonging to that figure (two-dimensional, three-dimensional). For example, if the opening when the entrance and exit door is opened is a rectangle, the intersection of the two diagonals is the geometric center.

[0015] The hypoxic room 2 provides a space with a low oxygen concentration. As shown in Fig. 1, the hypoxic space components that constitute the hypoxic space of the hypoxic room 2 include an air monitoring device 201, an air conditioner 202, a display device 203, exercise equipment 204, an indoor air exhaust opening 205, a hypoxic air supply opening 206, a biological information acquisition unit 207, and a partition unit 208. The above-mentioned hypoxic space components will be described in detail later.

[0016] <Machine room 3> As shown in Fig. 2, the machine room 3 is a space that houses the hypoxic air generator 30. The indoor temperature of the machine room 3 may be controlled within the range of 2°C to 30°C, for example, by an air conditioner (not shown). This makes it possible to easily adjust the temperature of the hypoxic room 2, since the hypoxic air supplied to the hypoxic room 2 will be close to the above temperature. In addition, this makes it possible to prevent the hypoxic air generator 30 from becoming overheated and becoming unable to operate. The machine room 3 and the hypoxic room 2 are separated by a wall. The wall may be, for example, a wall or window of a site-constructed structure, or may be an opaque wall assembled on site. A part of the wall may be a wall assembled on site, or a part of the wall may be a wall or window of a site-constructed structure. A hypoxic air generating device 30 is disposed in the machine room 3.

[0017] 2, the door 35 is disposed in the machine room 3. The area of ​​the door 35 is set to 8.0% or less, desirably 6.0% or less, and preferably 4.0% or less of the area of ​​the walls of the machine room 3 excluding the ceiling and floor.

[0018] The hypoxic air generator 30 is a generator of hypoxic air having a function of separating the atmosphere into hypoxic air and hyperxic air. The hypoxic air generator 30 can efficiently generate air with an oxygen concentration controlled to 2.0 to 12.0%, and can efficiently reduce the amount of oxygen in the hypoxic room 2. The oxygen concentration generated by the hypoxic air generator 30 of this embodiment is so low that it adversely affects the human body. For example, if the above-mentioned hypoxic air is directly inhaled, there is a possibility that hypoxemia will be caused. The details will be described later, but in order to prevent such a situation, the position of the hypoxic air supply opening 206, the position of the air monitoring device 201, etc. are appropriately set.

[0019] The hypoxic air generator 30 has an outlet 301 that discharges oxygen-rich air generated by separating hypoxic air from atmospheric air. The height of the oxygen-rich air outlet 301 should be 1.8 m or more above the floor (more desirably, 2.0 m or more). As oxygen-rich air is discharged, it is dangerous to bring a fire close to it. In this regard, according to the configuration of this embodiment, the outlet 301 is set at a high position, making it difficult for people and fire to get close, thereby reducing the risk. The hypoxic air generator 30 may be a device that adds nitrogen to the air from a nitrogen cylinder. In addition, the machine room 3 may further include a device other than the low oxygen air generating device 30.

[0020] <Control Room 4> In this embodiment, the control room 4 is provided separately from the low oxygen room 2, and houses the information processing device 1. The oxygen concentration in the control room 4 is about 20%, which is normal. The information processing device 1 is disposed in the control room 4. The information processing device 1 performs various controls to realize a low oxygen environment. The information processing device 1 is a computer that executes various processes to realize a low oxygen environment. The computer may be a stationary computer, a mobile notebook computer, or a tablet terminal. The information processing device 1 performs various processes in cooperation with the operation of the above-mentioned hypoxic air generating device 30 and hypoxic space components (e.g., air monitoring device 201, air conditioning device 202, display device 203, exercise equipment 204, indoor air exhaust opening 205, hypoxic air supply opening 206, biometric information acquisition unit 207, partition unit 208, etc.).

[0021] <Hardware configuration of information processing device 1> The following describes the hardware configuration of the information processing device 1. Fig. 3 is a block diagram showing the hardware configuration of the information processing device 1 according to this embodiment. The information processing device 1 includes a CPU (Central Processing Unit) 11, a ROM (Read Only Memory) 12, a RAM (Random Access Memory) 13, a bus 14, an input / output interface 15, an output unit 16, an input unit 17, a storage unit 18, a communication unit 19, and a drive 20.

[0022] The CPU 11 executes various processes according to a program recorded in the ROM 12 or a program loaded from the storage unit 18 to the RAM 13. The RAM 13 also stores data and the like required for the CPU 11 to execute various processes. The CPU 11, the ROM 12, and the RAM 13 are interconnected via a bus 14. An input / output interface 15 is also connected to this bus 14.

[0023] An output unit 16, an input unit 17, a storage unit 18, a communication unit 19, and a drive 20 are connected to the input / output interface 15. The output unit 16 is composed of a display, a speaker, etc., and outputs various information as images and sounds. The input unit 17 is composed of a keyboard, a mouse, etc., and inputs various information. The storage unit 18 is composed of a hard disk, a DRAM (Dynamic Random Access Memory), etc., and stores various data. The communication unit 19 communicates with other devices via a network including the Internet.

[0024] Removable media 21, which may be a magnetic disk, an optical disk, a magneto-optical disk, or a semiconductor memory, is appropriately attached to the drive 20. Programs read from the removable media 21 by the drive 20 are installed in the storage unit 18 as necessary. The removable media 21 can also store various data stored in the storage unit 18 in the same manner as the storage unit 18.

[0025] The information processing device 1, the hypoxic air generating device 30, and the components of the hypoxic space such as the air monitoring device 201, the air conditioning device 202, and the display device 203 are connected to each other via a predetermined network such as the Internet which is not shown in FIG. 1.

[0026] <Components of Low Oxygen Room 2> The hypoxic room 2 provides a space with a low oxygen concentration. As shown in Fig. 1, the following elements are provided as hypoxic space components that constitute the hypoxic space of the hypoxic room 2: an air monitoring device 201, an air conditioner 202, a display device 203, exercise equipment 204, an indoor air exhaust opening 205, a hypoxic air supply opening 206, a biological information acquisition unit 207, and a partition unit 208. The hypoxic space components will be described below in order.

[0027] <Air monitoring device 201> The air monitoring device 201 detects, monitors, or measures the properties of the air in the hypoxic room 2. The air monitoring device 201 is a sensor box that monitors, for example, the concentration of oxygen in the air, the concentration of carbon dioxide in the air, the temperature of the air, the humidity of the air, and the like.

[0028] It should be noted that air monitoring device 201 is not limited to a configuration that measures all of oxygen, carbon dioxide, temperature, and humidity. Air monitoring device 201 may be specialized in measuring the oxygen concentration by omitting the configuration for measuring carbon dioxide, temperature, humidity, etc. from the configuration that measures the concentration of oxygen in the air, the concentration of carbon dioxide in the air, temperature, humidity, etc. Furthermore, air monitoring device 201 may use a sensor mounted on another device. For example, temperature may be measured using a temperature sensor provided in air conditioner 202 (described later), and humidity may be measured using a humidity sensor provided in a separately arranged dehumidifier.

[0029] It is preferable that the air monitoring device 201 accurately measures the oxygen and the like and that a fail-safe is taken into consideration. The air monitoring device 201 may have one sensor for monitoring oxygen, carbon dioxide, temperature, humidity, and the like, but it is preferable to have multiple sensors from the viewpoint of a fail-safe. For example, two or more oxygen sensors may be provided. When two or more oxygen sensors are provided in the air monitoring device 201, it is preferable that the information processing device 1 assigns a greater weight to the lower value among the values ​​detected by the two or more oxygen sensors. More specifically, the information processing device 1 may employ only the lower of the detection values ​​output by the air monitoring device 201, or may assign double weight to the lower of the detection values.

[0030] If a fail-safe is taken into consideration, the air monitoring device 201 may be provided with two or more sensors, and if a difference occurs between the two measurement values ​​that is greater than a predetermined value (e.g., 2.0% in absolute value, or preferably 1.0%, or 10.0% in percentage, or preferably 8.0%), the device may display an abnormality on the display device 203.

[0031] Furthermore, air monitoring device 201 may have separate sensors for control and display. This allows air monitoring device 201 to display a message indicating that an abnormality has occurred when one of the sensing units (e.g., oxygen sensor) malfunctions. This makes it easier for users, managers, etc. to notice the abnormality.

[0032] Also, to take fail-safe into consideration, it is advisable that the output of air monitoring device 201 is wired to information processing device 1 via an electric cable. Also, outputting current rather than voltage is advantageous from the standpoint of fail-safe, as it makes it easier to detect faults, including disconnections. This is because, when air monitoring device 201 monitors the current value, if there is a disconnection, the current value will definitely become 0.

[0033] ≪Air conditioner 202≫ The air conditioner 202 is, for example, a device (such as an air conditioner) that circulates air, adjusts temperature, and adjusts humidity in the hypoxic room 2. The air conditioner 202 can control the room temperature, humidity, or both of the hypoxic room 2. The air conditioner 202 of this embodiment is configured to be operable based on control from the information processing device 1.

[0034] ≪Display device 203≫ The display device 203 is, for example, a display that displays various information. The display device 203 is disposed in front of and away from a user of exercise equipment 204 (described later) in the hypoxic room 2. The display device 203 is a display of 24 inches or more, desirably 32 inches or more, and preferably 40 inches or more. The distance between the display device 203 and the exercise equipment 204 in the hypoxic room 2 may be within 5.0 m, desirably 3.0 m or less, and preferably 2.0 m or less.

[0035] The display device 203 may display, for example, the user's biological information, and may also display other quantities causally related thereto (e.g., exercise load, oxygen concentration in a low-oxygen room, altitude). The biological information is an index value that indicates the user's physical condition, such as heart rate, percutaneous arterial oxygen saturation (SpO2), blood pressure, etc.

[0036] ≪Exercise equipment 204≫ The low-oxygen room 2 according to this embodiment provides a space for training involving exercise. A stationary exercise machine 204 is provided. The user is a human being. The exercise machine 204 is, for example, a stationary exercise machine 204 such as an exercise machine 204 for training muscles or an aerobic exercise machine. More specifically, the stationary exercise machine 204 refers to an exercise machine 204 weighing 30 kg or more and / or an exercise machine 204 placed on the floor and / or an exercise machine 204 fixed to a wall, floor or ceiling, which can allow a person to exercise. Examples of stationary exercise equipment 204 include treadmills, fitness bikes, cross trainers, step machines, rowing machines, strength machines, abdominal machines, chest press machines, lat pulldown machines, shoulder press machines, leg extension machines, leg curl machines, leg press machines, bench presses, Smith machines, power racks, horizontal bars, cable machines, hip thrusts, swimming facilities, ball game facilities, running facilities, skiing facilities, cycling facilities, and the like.

[0037] <Indoor air exhaust opening 205> The indoor air exhaust opening 205 is an opening for replacing air containing carbon dioxide within the hypoxic room 2. The indoor air exhaust opening 205 allows the air within the hypoxic room 2 to be exhausted to the outside of the hypoxic room 2.

[0038] The indoor air exhaust opening 205 is composed of, for example, an exhaust port, an intake / exhaust port, a window, an entrance / exit door, and the like. The entrance / exit door refers to a door through which a user or the like enters and leaves the low-oxygen room 2. The windows and entrance / exit doors function as openings when opened. That is, even something that is not necessarily opened and closed for the purpose of ventilation, such as an entrance / exit door, can constitute the indoor air exhaust opening 205.

[0039] The number of indoor air exhaust openings 205 is not particularly limited, but in this embodiment, it is set to 1 to 5. When indoor air exhaust openings 205 are provided in multiple locations (for example, when provided as an exhaust port, a window, or an entrance / exit door), the number of indoor air exhaust openings 205 that are always open may be 0 to 2.

[0040] The indoor air exhaust opening 205 is located within 0.5 m, desirably within 0.3 m, and preferably within 0.2 m from the floor of the hypoxic room 2. This allows air in the hypoxic room 2 to be exchanged efficiently.

[0041] 1, indoor air exhaust opening 205 is provided in two places, a normally open exhaust port 205a and entrance / exit door 205b. Entrance / exit door 205b constituting indoor air exhaust opening 205 may be a hinged door that opens inward, or may be a sliding door. By using an inward-opening hinged door or sliding door, it is possible to suppress an increase in oxygen concentration in hypoxic room 2 that accompanies opening and closing of the entrance / exit door, compared to a hinged door that opens outward, and it is possible to quickly create a hypoxic state in hypoxic room 2.

[0042] When the entrance / exit door 205b is a sliding door, a windbreak of 0.1 m or more, desirably 0.3 m or more, and preferably 0.5 m or more in the height direction may be provided on the upper part of the sliding door, and the windbreak may be light-transmitting. Furthermore, the handle 120 provided on the entrance / exit door 205b and provided in the low-oxygen room 2 may be provided at a predetermined height (e.g., 0.5 m or less, 0.3 m or less) from the floor of the entrance / exit door 205b. This allows even a person who is feeling unwell and crouching down to easily open the entrance / exit door 205b.

[0043] The area of ​​the entrance / exit door 205b relative to the area of ​​the walls excluding the ceiling and floor of the hypoxic room 2 is 10.0% or less, desirably 8.0% or less, and preferably 6.0% or less.

[0044] Indoor air exhaust opening 205 may be normally open, or may be openable and closable, and may open toward the outside of hypoxic room 2 by air pressure. There may also be a correlation between the area of ​​indoor air exhaust opening 205 and the hypoxic supply capacity. For example, the area of ​​indoor air exhaust opening 205 may be made larger as the hypoxic supply capacity increases. When the hypoxic supply capacity is high, the area of ​​indoor air exhaust opening 205 may be set to 8% or more of the area of ​​the walls excluding the ceiling and floor of hypoxic room 2.

[0045] The hypoxic room 2 may have only one entrance / exit door 205b for users excluding the emergency door. This allows the hypoxic state in the hypoxic room to be kept stable. There may be only one entrance / exit door in the hypoxic room 2, in which case there may be only one, including the emergency door.

[0046] Furthermore, only the entrance / exit door 205b may be considered as the indoor air exhaust opening 205 of the hypoxic room 2. If there is also a door 35 (see FIG. 2) connecting to the machine room 3 in which the hypoxic air generating device 30 is installed, the door 35 may also be considered as the indoor air exhaust opening 205. Doors that are intended to be normally closed, such as emergency doors, do not need to be considered. Furthermore, it may be understood that windows and entrance / exit doors do not fall under the category of indoor air exhaust opening 205.

[0047] When the exhaust port or intake / exhaust port is the indoor air exhaust opening 205, a fan may be provided at the indoor air exhaust opening 205 (exhaust port 205a) as a means for forcibly exhausting air inside the hypoxic room 2 to the outside of the hypoxic room 2. Also, a bidirectional fan may be provided as a means for forcibly drawing air outside the hypoxic room 2 into the hypoxic room 2. In this case, the exhaust force may be greater than the intake force. This allows the air inside the hypoxic room 2 to be replaced efficiently. Intake is effective when multiple hypoxic rooms 2 share the hypoxic air generating device 30. The fan may be controlled by the information processing device 1.

[0048] Furthermore, when indoor air exhaust opening 205 is used as an exhaust port or an intake / exhaust port, indoor air exhaust opening 205 may be provided in entrance / exit door 205b. By configuring indoor air exhaust opening 205 to automatically close when entrance / exit door 205b is opened, the exhaust of air from within low oxygen room 2 can be suppressed.

[0049] <Low oxygen air supply opening 206> The hypoxic air supply opening 206 supplies air having an oxygen concentration lower than the oxygen concentration inside the hypoxic room 2 to the hypoxic room 2. The hypoxic air supply opening 206 is, for example, a hypoxic air outlet through which air (fluid) having a low oxygen concentration is supplied from the hypoxic air generating device 30.

[0050] Requirements for the low oxygen air supply opening 206 will be explained in turn. The number of hypoxic air supply openings 206 is not particularly limited, but in this embodiment it is between 1 and 4, and preferably between 1 and 2. In the hypoxic room 2 in this example, one opening is preferable, but if the area of ​​the hypoxic room 2 exceeds 200 square meters, multiple openings rather than one may be preferable. By arranging multiple hypoxic air supply openings 206, hypoxic air can be supplied evenly within the hypoxic room 2.

[0051] There is no particular limitation on the opening direction of the hypoxic air supply opening 206. For example, the opening direction of the hypoxic air supply opening 206 may be downward (toward the floor) when provided in a ceiling, and may be horizontal when provided in a wall.

[0052] The position of the hypoxic air supply opening 206 will be described. The position of the hypoxic air supply opening 206 in this embodiment is set higher than the position of the indoor air exhaust opening 205. In comparing the heights, the top, the center, and the bottom may be compared, or a combination of these, for example, the top and the bottom, or the center and the bottom, may be compared. The hypoxic air supply opening 206 may be in the ceiling, in a duct, or in a wall such as a side wall. It is also desirable to arrange at least one hypoxic air supply opening 206 between the indoor air exhaust opening 205 and the air monitoring device 201.

[0053] The lowest part of the hypoxic air supply opening 206 of the hypoxic room 2 is located 1.8 m or more, desirably 2.0 m or more, and preferably 2.5 m or more, measured from the floor. In addition, the lowest part of the hypoxic air supply opening 206 is located at the ceiling of the hypoxic room 2 or within 0.5 m, desirably within 0.3 m, and preferably within 0.2 m from the ceiling. This ensures safety. As described above, when there are multiple hypoxic air supply openings 206, it is preferable that at least one of the positions of the hypoxic air supply openings 206 from the floor or the positions of the hypoxic air supply openings 206 from the ceiling is within the above range, and it is more preferable that all of the hypoxic air supply openings 206 are within the above range. By satisfying the above requirements, the risk of the user directly inhaling hypoxic air can be reduced. Hypoxic air can have adverse effects on the human body, but by locating the hypoxic air supply opening 206 at a high position that satisfies the height conditions described above, the risk of the user directly inhaling hypoxic air can be reduced. Furthermore, by adopting the positional relationship of the present embodiment described above between the low oxygen air supply opening 206 and the indoor air exhaust opening 205, air can be efficiently exchanged. That is, air can be efficiently exhausted from inside the low oxygen room 2 and low oxygen air can be efficiently supplied to the low oxygen room 2.

[0054] A fan may be provided in the flow path connected to the opening of the hypoxic air supply opening 206 as a means for forcibly discharging hypoxic air into the hypoxic room 2. A bidirectional fan may also be provided as a means for forcibly drawing in air within the hypoxic room 2. The discharge force may be greater than the intake force. This allows the air within the hypoxic room 2 to be replaced efficiently. Intake is effective when multiple hypoxic rooms 2 share the hypoxic air generator 30.

[0055] <Biometric information acquisition unit 207> The biological information acquiring unit 207 monitors the condition of the person to be monitored. From the viewpoint of further improving safety, it is preferable to provide the biological information acquiring unit 207. The person to be monitored is, for example, a trainee who trains in the hypoxic room 2, or a user who experiences a hypoxic environment in the hypoxic room 2 without training.

[0056] The biometric information acquiring unit 207 acquires biometric information of the user. Examples of the biometric information of the user include SpO2 and heart rate. SpO2 is percutaneous arterial blood oxygen saturation and can be measured by a pulse oximeter. Heart rate is the number of times the heart beats per minute, and here, the measured pulse rate is taken as the heart rate.

[0057] The biological information acquisition unit 207 is a device carried by a user of the hypoxic room 2. The biological information is sent from the biological information acquisition unit 207 to the information processing device 1. The control unit 31 of the information processing device 1 acquires the biological information. The measurement of the biological information may be performed on the user in the hypoxic room 2, or the measurement may be started before the user enters the hypoxic room 2. The SpO2 and heart rate are acquired by the biological information acquisition unit 207, such as a pulse oximeter or a heart rate monitor. The biological information acquisition unit 207 may be a wearable terminal worn by the user, such as a smart watch. The biological information acquisition unit 207 transmits the measurement value of the biological information to the information processing device 1 in real time or at a predetermined timing. Note that the method of acquiring the biological information by the information processing device 1 is not limited to this method, and various methods can be adopted. For example, the information processing device 1 may be configured to acquire the biological information at a timing specified by an administrator.

[0058] When determining a representative value for a value that should be monitored for a decrease, such as SpO2, weighting may be given to values ​​that are measured on the lower side (e.g., excluding one or more of the larger measured values ​​and weighting the lower measured values ​​twice as much). Conversely, when determining a representative value for a value that should be monitored for an increase, such as heart rate, weighting may be given to values ​​that are measured on the higher side (e.g., excluding one or more of the smaller measured values ​​and weighting the higher measured values ​​twice as much). This allows for monitoring that takes more of a fail-safe into consideration.

[0059] When training starts, the value of the vital information may move in a direction that should be monitored. For example, after training starts, SpO2 tends to decrease, and heart rate tends to increase. The vital information value may be monitored based on its change (e.g., difference from a reference value, rate of decrease / increase, decrease / increase trend, decrease / increase pattern). This allows for more rapid monitoring.

[0060] The value of the biological information may be monitored by comparing it with the past data (e.g., absolute value, change) of the person to be monitored. This allows for flexible monitoring according to the person to be monitored (e.g., user, trainee).

[0061] The value of the vital information may be monitored by comparing it with standard data (e.g., absolute value, change) of the person being monitored. The standard data may be for each profile (e.g., gender, years of experience, basic physical strength, occupation, hobbies) of the person being monitored (e.g., user, trainee). The standard data may be for each degree of poor health (e.g., no problem, worsening health). This allows for more accurate monitoring.

[0062] There are also cases where it is desirable to monitor the absolute value of the biological information. The absolute value of SpO2, which is the monitoring criterion among the biological information, can be set to 75% or more, desirably 78% or more, and preferably 80% or more. Furthermore, the information processing device 1 may display on the display device 203 a recommendation to increase exercise intensity by referring to the value of SpO2. For example, the absolute value of SpO2, which is the criterion for increasing exercise intensity in this case, can be set to 95%, desirably 90%.

[0063] Furthermore, the information processing device 1 may monitor the amount of change in the biological information and the value of the biological information itself in monitoring the biological information. This is more beneficial from the viewpoint of fail-safety because it can prevent monitoring errors even if there is an error in the result of monitoring the change in the biological information (e.g., an error in measuring the reference value).

[0064] Furthermore, other quantities that are causally related to the biological information (e.g., exercise load, oxygen concentration in a low-oxygen room) may be taken into account in addition to the biological information value, allowing for more accurate monitoring.

[0065] <Partition 208> The partition 208 separates the inside of the hypoxic room 2 from the outside of the hypoxic room 2 so that air does not circulate freely. The partition 208 is, for example, a partition, a ceiling or floor of a building, a wall of a building, or a window of a building. The partition may be one for an office, may be a prefabricated one, or may be a constructed wall.

[0066] The hypoxic room 2 may be manufactured within a building using the partition 208, and may be transportable. It may be one that needs to be disassembled once for transportation. At least a part of the partition 208 of the hypoxic room 2 may utilize the ceiling, floor, wall, or window of a building. This can reduce the total manufacturing cost of the hypoxic room 2 or the manufacturing cost per user.

[0067] Conventionally, it has been thought that special construction is required to maintain airtightness of the hypoxic room 2. However, if a normal partition is used as the partition 208 of the hypoxic room 2 and no additional construction is performed to maintain airtightness, the air will naturally escape, eliminating the need for a constantly open exhaust port and reducing the manufacturing costs of the hypoxic room 2. In this configuration, it is preferable to perform a preparatory operation for a predetermined period of time (e.g., one hour or more) to put the hypoxic room 2 into a hypoxic state. The information processing device 1 can achieve greater efficiency by starting the above-mentioned preparatory operation at a preset operation start time.

[0068] In addition, at least a part of the partition 208 of this embodiment is a see-through area 130. The see-through area 130 is provided so as to include at least a part of a position 0.0 to 0.7 m above the floor surface. The area of ​​the see-through area 130 is set to 1.0 square meters or more. The area of ​​the see-through area 130 is desirably 1.5 square meters or more, and preferably 2.0 square meters or more. By providing the see-through area 130, it becomes possible to see a person who feels sick and crouches down in the low-oxygen room 2 from outside the room. The partition 208 having the see-through area 130 may be a partition in which at least the part other than the frame part below a predetermined height (for example, 1.2 m±0.4 m) is made light-transmittable, or may be a partition in which the part other than the frame part is made light-transmittable from top to bottom.

[0069] <Positional relationship of components of hypoxic space> Next, the positions and the mutual positional relationships of the hypoxic space components will be described. The hypoxic space components for which the positions and the mutual positional relationships are important are the air monitoring device 201, the exercise equipment 204, the indoor air exhaust opening 205, the hypoxic air supply opening 206, the biological information acquisition unit 207, the partitioning unit 208, and the like.

[0070] The height of the air monitoring device 201 from the floor is set lower than the height of the hypoxic air supply opening 206 from the floor.

[0071] In the present embodiment, the distance from the exhaust port 205a as the indoor air exhaust opening 205 to the hypoxic air supply opening 206 is shorter than the distance from the exhaust port 205a as the indoor air exhaust opening 205 to the air monitoring device 201. That is, when the distance from the exhaust port 205a as the indoor air exhaust opening 205 to the hypoxic air supply opening 206 is distance A, and the distance from the exhaust port 205a as the indoor air exhaust opening 205 to the air monitoring device 201 is distance B, there is at least one hypoxic air supply opening 206 that satisfies the requirement of A < B.

[0072] In a plan view (a plane parallel to the floor), it is desirable that the distance from the exhaust port 205a as the indoor air exhaust opening 205 to the hypoxic air supply opening 206 is set to a length that is 30.0% or more and 70.0% or less of the distance from the exhaust port 205a as the indoor air exhaust opening 205 to the air monitoring device 201. Thereby, the influence of the indoor air exhaust opening 205 is reduced, and it is avoided that the air monitoring device 201 measures a high oxygen concentration, which is beneficial from the viewpoint of fail-safe.

[0073] Furthermore, the distance from exhaust port 205a as indoor air exhaust opening 205 to hypoxic air supply opening 206 is longer than the distance from hypoxic air supply opening 206 to air monitoring device 201. That is, when distance A is the distance from exhaust port 205a as indoor air exhaust opening 205 to hypoxic air supply opening 206, and distance C is the distance from hypoxic air supply opening 206 to air monitoring device 201, the requirement of A>C is satisfied. This also reduces the influence of indoor air exhaust opening 205 and prevents the oxygen concentration from being measured as being too high, which is beneficial from the standpoint of fail-safe.

[0074] The height of the air monitoring device 201 may be equal to or greater than 1.5 m and less than 3.0 m. The height of the air monitoring device 201 may be less than the height of the hypoxic air supply opening 206.

[0075] Furthermore, the low oxygen air supply opening 206 may be located within 3.0 m, desirably within 2.0 m, and preferably within 1.0 m from the line connecting the indoor air exhaust opening 205 and the air monitoring device 201 in a plan view.

[0076] By adopting such a positional relationship, the influence of the room air exhaust opening 205 during measurement is reduced, and it is possible to prevent the oxygen concentration from being measured as being too high, which is beneficial from the viewpoint of fail-safe. It is also possible to prevent the oxygen concentration from being measured as being too low.

[0077] When the size of indoor air exhaust opening 205 is E square meters (e.g., 2.0 square meters) and the volume of low oxygen room 2 is R m3 (e.g., 60 m3), it is desirable to set R in the ranges of R ≧ 25 × E, R ≧ 35 × E, and R ≧ 50 × E. Setting it in this range reduces the influence of indoor air exhaust opening 205 and prevents the oxygen concentration from being measured as being too high, which is beneficial from the standpoint of fail-safe.

[0078] It is preferable to similarly define the distance between indoor air exhaust opening 205 and exercise equipment 204 in low oxygen room 2. For example, the distance from exhaust port 205a as indoor air exhaust opening 205 to low oxygen air supply opening 206 is set to be longer than the distance from low oxygen air supply opening 206 to exercise equipment 204 in low oxygen room 2. By adopting this positional relationship, the low oxygen environment around the user of exercise equipment 204 is accurately maintained.

[0079] In addition, the exercise equipment 204 in the low-oxygen room 2 is arranged so that the user can train with his / her back facing the indoor air exhaust opening 205, thereby maintaining the low-oxygen environment for the user. "With his / her back facing" means that, when viewed from the indoor air exhaust opening 205, more of the user's back is visible than his / her chest.

[0080] <Functional configuration of information processing device 1> Fig. 4 is a functional block diagram showing an example of a functional configuration of the information processing device 1 according to this embodiment. As described above, the information processing device 1 has a CPU 11, a storage unit 18, and a communication unit 19 as a hardware configuration. In the CPU 11 of the information processing device 1, a control unit 31 functions during operation. Also, an information DB 41 that stores information is provided in the storage unit 18 of the information processing device 1 shown in Fig. 4.

[0081] 4, the information processing device 1 of this embodiment transmits, receives, or transmits / receives various information to / from components of the hypoxic space, such as the hypoxic air generating device 30, the air monitoring device 201, the air conditioning device 202, and the display device 203. The control unit 31 of the information processing device 1 monitors the oxygen concentration and carbon dioxide concentration, and performs various controls such as the oxygen concentration, the carbon dioxide concentration, the temperature, and the humidity. The information processing device 1 may also transmit, receive, or transmit / receive various information to / from the exercise equipment 204 in the hypoxic room 2.

[0082] Information is input to the information processing device 1 from the hypoxic air generating device 30 and the components constituting the hypoxic space, such as the air monitoring device 201, the air conditioning device 202, the exercise equipment 204, the indoor air exhaust opening 205, the hypoxic air supply opening 206, and the biological information acquisition unit 207. The information processing device 1 controls the hypoxic air generating device 30 and the various devices included in the components constituting the hypoxic space. The information processing device 1 may be composed of a single computer, or may be composed of multiple computers arranged in each of the various devices. In the following description, "control" refers simply to control by the information processing device 1, but the structure and configuration may be such that various numerical values ​​are controlled.

[0083] In the following description, the upper and lower limits of the numerical ranges are independent of each other, and for example, a lower limit indicated as "desirably" may be combined with an upper limit indicated as "preferably". The upper and lower limits of the numerical ranges should be understood as "not less than" and "not more than" unless otherwise specified. However, when the upper or lower limit is excluded, it is also possible to replace it with "less than" and "over", in which case "less than" and "over" are explicitly stated.

[0084] Numerical values ​​are understood to include numerical ranges that would be the same if rounded up or down. For example, "2.0 m" is understood to mean "1.95 m or more but less than 2.05 m." Similarly, numerical ranges that include boundaries such as "less than" should be understood to include values ​​that would be the same if rounded up or down, and numerical ranges that do not include boundaries such as "less than" should be understood to exclude values ​​that would be the same if rounded up or down.

[0085] <Air pressure control> The control unit 31 of the information processing device 1 controls the air pressure inside the hypoxic room 2 to be slightly higher than the air pressure outside the hypoxic room 2. The air pressure inside the hypoxic room 2 may be slightly higher than the air pressure outside the hypoxic room, for example, due to the flow rate of hypoxic air supplied from the hypoxic air supply opening 206. This makes it possible to prevent high oxygen air from leaking in from outside the hypoxic room 2.

[0086] The control unit 31 of the information processing device 1 sets the oxygen concentration of the hypoxic air supplied from the hypoxic air supply opening 206 to 12.0% or less, which is also 1.0% or more lower than the oxygen concentration in the hypoxic room. This makes it possible to quickly put the inside of the hypoxic room 2 into a hypoxic state.

[0087] The control unit 31 of the information processing device 1 maintains the hypoxic room 2 at normal pressure. Alternatively, a means for controlling the air pressure inside the hypoxic room 2 may not be provided. Furthermore, the partition 208 of the hypoxic room 2 may not be provided with a configuration for maintaining the hypoxic room 2 at high or low pressure.

[0088] In the hypoxic room 2, it is sufficient that the control unit 31 of the information processing device 1 measures, monitors and / or controls at least the oxygen concentration, and it is also preferable that the control unit 31 of the information processing device 1 measures, monitors and / or controls at least the carbon dioxide concentration. Furthermore, in the hypoxic room 2, the control unit 31 of the information processing device 1 desirably measures, monitors and / or controls humidity, and preferably may also measure, monitor and / or control odors and dust (PM2.5, etc.).

[0089] Next, a description will be given of an example of controlling the oxygen concentration and carbon dioxide concentration in the low oxygen room 2. In the following description, % for the oxygen concentration, carbon dioxide concentration, etc. indicates % by volume.

[0090] <Oxygen concentration control> The oxygen concentration can be controlled, for example, by the information processing device 1 controlling the low oxygen air generating device 30. The standard for oxygen concentration will be described. The current local air pressure P can be calculated using the following formula 1. In formula 1, P represents the current local air pressure (hPa), P0 represents the air pressure at an altitude of 0 m (hPa), h represents the altitude (m), and T represents the temperature (°C).

[0091] Assuming that the oxygen concentration at an altitude of 0 m is 21% and the atmospheric pressure is 1013.25 hPa, the relationship between altitude and oxygen concentration in the atmosphere can be shown as in Figure 5. Figure 5 is a table showing the relationship between altitude and oxygen concentration in the atmosphere.

number

[0092] For example, the air pressure at an altitude of 3500m can be calculated as 648.62hpa. Although the oxygen concentration remains at 21% even at an altitude of 3500m, because the air is thinner, the amount of oxygen is calculated as 21% x 648.62hpa ÷ 1013.25hpa = 13.4%. Thus, there is a correlation between altitude and oxygen concentration. By utilizing this correlation, an environment with an oxygen concentration corresponding to a specified altitude can be realized.

[0093] The oxygen concentration in the low oxygen room 2 in this embodiment is, for example, 12.6 to 17.4% (corresponding to an altitude of 4000m to 1500m), preferably 13.4 to 15.3% (corresponding to an altitude of 3500m to 2500m), and is controlled with an accuracy of ±1.0%, preferably ±0.5%.

[0094] Furthermore, the oxygen concentration discharged from the hypoxic air supply opening 206 is controlled to, for example, 2.0 to 12.0%. The oxygen concentration can be desirably set to 2.0 to 10.0%, and preferably 2.0 to 8.0%. The difference between the oxygen concentration discharged from the hypoxic air supply opening 206 and the oxygen concentration in the hypoxic room is, for example, 1.0% or more, desirably 3.0% or more, and preferably 5.0% or more. This allows the interior of the hypoxic room 2 to be quickly brought to a hypoxic state.

[0095] The oxygen concentration in the low-oxygen room 2 may be changed depending on the exercise intensity (absolute heart rate) and / or the type of training. For example, the oxygen concentration for strength training or running may be set higher than the oxygen concentration for walking. The oxygen concentration in the low-oxygen room 2 when the exercise intensity (absolute heart rate) is strong may be 0.5 to 3.0% higher, and preferably 1.0 to 2.0%, per 30 heart rate difference than the oxygen concentration in the low-oxygen room 2 when the exercise intensity (absolute heart rate) is weak.

[0096] In addition, the oxygen concentration may be adjusted according to the type and intensity of training (e.g., running, strength training, etc.), age, etc. For example, if the maximum heart rate of a 35-year-old is 185, the heart rate difference may be set to be less than 40, since the heart rate difference is between 120 (64%) and 160 (86%).

[0097] <Temperature control> The control unit 31 of the information processing device 1 controls the air conditioner 202 to control the temperature of the low oxygen room 2 to a temperature range of, for example, 10.0 to 30.0° C., desirably 15.0 to 25.0° C., and preferably 18.0 to 22.0° C. Alternatively, the control unit 31 may set a temperature range according to a high altitude environment corresponding to the set oxygen concentration and altitude.

[0098] The temperature difference between the inside and outside of indoor air exhaust opening 205 may be 1.0°C or more, desirably 2.0°C or more, and preferably 3.0°C or more, and the temperature in low oxygen room 2 may be lower. If the temperature in low oxygen room 2 is lower, when indoor air exhaust opening 205 is opened, the air below flows out of low oxygen room 2 and the air above flows into low oxygen room 2. The air that flows in has a high oxygen concentration, but since low oxygen air supply opening 206 is nearby, the effect is mitigated and the air monitoring device 201 is less likely to be affected. In addition, since the air below, which is closer to the floor and contains a relatively large amount of carbon dioxide, flows out of low oxygen room 2, a ventilation effect can be expected.

[0099] <Control of carbon dioxide concentration> The carbon dioxide concentration is an important indicator because it may cause carbon dioxide poisoning. The control unit 31 controls the carbon dioxide concentration to realize a safer hypoxic environment. The carbon dioxide concentration in the hypoxic room 2 is controlled to, for example, 10,000 ppm or less, desirably 8,000 ppm or less, and preferably 6,000 ppm or less.

[0100] The carbon dioxide concentration can be measured, for example, by the air monitoring device 201. The control unit 31 may also estimate the exhaled air volume according to the number of users x exercise intensity (heart rate) and calculate the amount of carbon dioxide in the hypoxic room 2 based on this exhaled air volume. Even if the environment of the hypoxic room 2 is the same, the exhaled air volume (amount of carbon dioxide) varies depending on the type of exercise. For example, the exhaled air volume (amount of carbon dioxide) is greater when running on a treadmill than when strength training is performed. The control unit 31 may correct the amount of carbon dioxide calculated depending on the type of exercise, such as running or strength training.

[0101] Furthermore, the control unit 31 may change the flow rate setting in the hypoxic air generating device 30 based on the amount of carbon dioxide (carbon dioxide concentration). For example, the control unit 31 obtains the carbon dioxide concentration based on a measured value, a calculated value, or both, and changes the flow rate of the hypoxic air generating device 30 according to the carbon dioxide concentration.

[0102] <Humidity control> Humidity may affect the breathlessness felt by the user. For this reason, the control unit 31 may control the humidity to an appropriate range. If the humidity is not appropriately controlled, the user may be slow to realize that he or she is feeling unwell.

[0103] An example of humidity control will be described below. The control unit 31 controls the humidity in the low oxygen room 2 to, for example, 20.0 to 70.0%, desirably 40.0 to 60.0%, and preferably 45.0 to 55.0%.

[0104] <Responses to physical conditions> The control unit 31 of the information processing device 1, for example, as a monitoring control, sets a reference value for the value of the bioinformation acquired from the bioinformation acquisition unit 207, and judges the state of the human body based on the reference value. The reference value can be set based on the value of the bioinformation such as SpO2 and heart rate at the beginning of measurement. This allows the information processing device 1 to perform monitoring based on the normal value of the user who is the monitoring subject. The reference value can be a representative value such as a value excluding the average value, majority value, most frequent value, maximum value, and minimum value of the past multiple times. A representative value is a value that is more likely to be the same as a single measured value. This allows more accurate monitoring.

[0105] The control unit 31 of the information processing device 1 may issue a message encouraging a monitoring subject whose bioinformation value obtained based on the bioinformation acquisition unit 207 is on a worsening trend to take a deep breath. For example, when the information processing device 1 detects that the bioinformation value is on a worsening trend, the control unit 31 may execute a process of transmitting information to the display device 203 to display the worsening trend and a message encouraging a deep breath. In addition, when the bioinformation (e.g., SpO2, heart rate) of a certain percentage (e.g., more than half, more than two-thirds) of the monitoring subjects in the hypoxic room 2 is on a trend that requires attention, the control unit 31 may control the oxygen concentration in the hypoxic room to be high. For example, the control unit 31 performs control to close the hypoxic air supply opening 206 and open the room air exhaust opening 205.

[0106] The control unit 31 of the information processing device 1 may control the oxygen concentration in the hypoxic room to be higher if the values ​​of biological information (e.g., SpO2, heart rate) of a certain percentage (e.g., more than half, more than two-thirds) of the monitoring subjects (e.g., users, trainees) in the hypoxic room 2 show a tendency that requires caution. For example, the control unit 31 performs control to close the hypoxic air supply opening 206 and open the room air exhaust opening 205.

[0107] The biological information may also be the subjective intensity of exercise. The subjective intensity of exercise is an index that changes, for example, when the subject recognizes that the exercise is difficult or when there is a change in the subject's movement. The subjective intensity of exercise is acquired by the control unit 31 by monitoring changes in facial expression, complexion, etc., changes in limb movements, a decrease in running speed, etc. The control unit 31 may determine changes in facial expression, complexion, etc., changes in limb movements, a decrease in running speed, etc. by analyzing images acquired by an imaging device, or may determine them based on detection values ​​of various sensors that detect movements such as an acceleration sensor.

[0108] Furthermore, the control unit 31 of the information processing device 1 may execute a usage halt process to halt use of the low oxygen room 2 when a person remains in the low oxygen room 2 continuously for a predetermined time or longer. The usage halt process for the low oxygen room 2 may include at least one of a process of issuing a notification to encourage people to leave the low oxygen room 2, a process of increasing the oxygen concentration in the low oxygen room 2, and a process of opening the entrance / exit door. This makes it possible to prevent the low oxygen room 2 from being used for a predetermined time or longer. When implementing a process to open the entrance / exit door, it is preferable that the control unit 31 has an automatic opening / closing function to open and close the entrance / exit door remotely or automatically.

[0109] The configuration of the above embodiment can be modified as appropriate. For example, a surveillance camera may be installed in the hypoxic room 2. This allows the hypoxic training facility 100 to be operated unmanned, such as a 24-hour gym with no staff.

[0110] Furthermore, a human presence sensor may be provided in the low oxygen room 2 as the biological information acquisition unit 207. The human presence sensor may be installed, for example, so as to detect that there is no human body above a predetermined height (e.g., 1.2 m) in the low oxygen room 2. This allows the human presence sensor to detect a person who has become unwell and crouched down in the low oxygen room 2. Furthermore, the control unit 31 may perform control so as to increase the oxygen concentration in the low oxygen room 2 based on the detection result of the human presence sensor. For example, a means for forcibly taking in outside air into the low oxygen room 2 may be provided.

[0111] The human presence sensor may also be configured to detect the presence of a human body at or above a predetermined height (e.g., 1.8 m, 2.0 m) in the hypoxic room 2. This allows the control unit 31 to detect the risk of the user directly inhaling hypoxic air. Based on the detection result, the control unit 31 of the information processing device 1 may control the supply of hypoxic air from the hypoxic air supply opening 206 to be weakened or stopped.

[0112] In the above embodiment, various controls are executed by the information processing device 1, but the present invention is not limited to this configuration. For example, various settings may be performed for each device. In the above embodiment, the desirable and suitable numerical ranges are preferred numerical ranges, and the present invention is not necessarily limited to the above-mentioned numerical ranges.

[0113] In addition, within the scope of the invention, the components in the above-described embodiments may be replaced with well-known components, and the above-described modified examples may be combined as appropriate.

[0114] (Advantageous Effects of the Present Embodiment) According to the above-described embodiment, it is possible to provide a hypoxic room 2 and a hypoxic training facility 100 in which the arrangement and functions of the functional parts constituting the hypoxic space are more optimized than in the prior art. Health accidents caused by a hypoxic state are prevented, and users can safely carry out simulated high altitude training.

[0115] [Second embodiment] (overview) In the first embodiment, a low-oxygen training facility for training in a low-oxygen state is disclosed. In the second embodiment, a refreshment facility or rest facility based on a low-oxygen state is provided. The low-oxygen facility is a facility intended to allow people to rest and / or change their mood. The low-oxygen facility is not a facility intended to allow people to exercise, such as a training facility equipped with stationary exercise equipment. The low-oxygen facility is equipped with a low-oxygen room. No stationary exercise equipment is provided. The low-oxygen room is equipped with an entrance / exit door for users to enter and exit the low-oxygen room, and a low-oxygen air supply opening through which air with a low oxygen concentration is supplied into the low-oxygen room. The floor area of ​​the low-oxygen room is (2.0×N) m when the capacity is N people. 2 The following is a space-saving refreshment facility.

[0116] (Overall composition) <500 Hypoxic Facilities> 6 is a schematic diagram showing the configuration of a low-oxygen facility 500 according to this embodiment. The low-oxygen training facility 100 according to the first embodiment and the low-oxygen facility 500 according to the second embodiment differ in at least one of oxygen concentration, equipment (e.g., stationary exercise equipment), shape, area, temperature, etc.

[0117] The hypoxic facility 500 includes an information processing device 1, a hypoxic room 2, a machine room 3, and a control room 4. As with the hypoxic training facility 100 of the first embodiment, the machine room 3 houses a hypoxic air generator 30, the illustration of which is omitted in FIG. In the following, unless otherwise specified, in the second embodiment, the description of the same components as those in the first embodiment will be omitted and the same reference numerals will be used. The components constituting the low oxygen facility 500 according to the second embodiment will be described in order of differences from the first embodiment.

[0118] <Low oxygen room 2> The low-oxygen room 2 according to the second embodiment is a space intended for getting used to a low-oxygen environment and performing yoga or other activities for refreshing. No stationary exercise equipment is placed in the low-oxygen room 2 of this embodiment. In the low-oxygen room 2, one may stay in a resting state or perform activities such as yoga or stretching for the purpose of refreshing, resting, or changing one's mood, but high-intensity exercise using stationary exercise equipment is not preferable. In addition, the low-oxygen room 2 is for people to stay in, and differs from a space intended for storing plants such as vegetables, a space intended for storing objects such as artworks, or a space intended for housing animals other than humans such as horses in at least one or more of oxygen concentration, fixtures, shape, area, temperature, etc.

[0119] The low-oxygen room 2 may be a sauna-type low-oxygen room or a standing-type low-oxygen room. A sauna-type low-oxygen room is a space provided with seating means such as chairs, benches, or high benches (bar-shaped benches on which one can rest in a position similar to standing) for people to sit and stay in. Seat means are items designed for people to sit in. A standing-type low-oxygen room is a space not provided with seating means for people to stay in a standing position.

[0120] The hypoxic room 2 according to the second embodiment includes hypoxic space components similar to those of the first embodiment. However, instead of the exercise equipment 204, for example, a chair 209 is included. This is not for the purpose of exercise, but for the purpose of getting used to the hypoxic environment as described above. The configurations of the air monitoring device 201, the air conditioner 202, the biological information acquisition unit 207, and the partition unit 208 are the same as those in the first embodiment, so a description thereof will be omitted.

[0121] <Capacity> A capacity is set for the low-oxygen room 2. The capacity of the low-oxygen room 2 refers to the number of people planned to be accommodated in the low-oxygen room 2. For example, the capacity of a standing-type low-oxygen room 2 may be set to 1 person, and the capacity of a sauna-type low-oxygen room 2 may be set to 10 people or less, desirably 5 people or less, and preferably 3 people or less. In this embodiment, it is not assumed that stationary exercise equipment will be placed, but if stationary exercise equipment is placed in the low-oxygen room 2, the number of such equipment can be used as the capacity.

[0122] In the case of a sauna-type hypoxic room in which no stationary exercise equipment is arranged in the hypoxic room 2, the capacity can be calculated based on the number of seating means. For example, if there are N seating means, the capacity is N people. If the width of the seat exceeds 0.6 m, the capacity can also be calculated by dividing the width by 0.6 m (rounded up to the nearest whole number). For example, if there are two benches with a seating width of 1.8 m, the capacity is 6 people. In the case of a standing-type hypoxic room in which no stationary exercise equipment or seating means (e.g. benches, chairs) are arranged in the hypoxic room 2, the capacity can be calculated based on the number of 1.0 m square floor spaces that can be secured. For example, the capacity of a standing-type hypoxic room with a floor space of 1.4 m square is 1 person. The capacity of a standing-type hypoxic room with a floor space of 1.0 m x 2.0 m is 2 people. In the case of a long and narrow room, where the capacity is 0 people, the capacity is 1 person.

[0123] In this embodiment, when the capacity of the low oxygen room 2 is N people, the floor area of ​​the low oxygen room 2 is, for example, (2.0 × N) m 2 For small size, the value is (1.5×N)m. 2 For smaller sizes, the value is (1.0×N)m. 2 The floor area of ​​the low oxygen room 2 is set as follows: Note that the values ​​of the floor area of ​​the low oxygen room 2 are merely examples and are not necessarily limited to these ranges.

[0124] ≪Display device 203≫ The display device 203 may be provided on the wall on the side of the indoor air exhaust opening 205. The hypoxic air supply opening 206 is provided on the wall opposite the wall on which the indoor air exhaust opening 205 is provided. When looking at the display device 203, a user facing the display device 203 will have his / her back to the hypoxic air supply opening 206. This can reduce the risk of the user directly inhaling hypoxic air.

[0125] The display device 203 is installed on the wall surface farther from the handle 120 of the entrance / exit door 205b. The display device 203 may also be installed on the wall surface closer to the handles 120, 121 of the entrance / exit door 205b (the wall surface closest to the handles 120, 121 of the entrance / exit door 205b or the wall surface forming an angle with the entrance / exit door 205b). This allows the user to immediately place their hand on the handle when they feel unwell inside the low oxygen room 2.

[0126] <Indoor air exhaust opening 205> The indoor air exhaust opening 205 shown in Fig. 6 can be installed at a location that suits the purpose. For example, the indoor air exhaust opening 205 can be installed within 0.5 m, preferably within 0.3 m, and more preferably within 0.2 m from the floor of the low oxygen room 2, thereby allowing efficient replacement of air in the low oxygen room 2. Alternatively, the indoor air exhaust opening 205 can be installed at a distance of 0.5 m or more, preferably 0.8 m or more, from the floor of the low oxygen room 2. In this case, the oxygen concentration at a low position in the low oxygen room 2 is less likely to decrease, and if a person feels unwell and crouches down in the low oxygen room 2, they can inhale air with a relatively high oxygen concentration.

[0127] <<Entry / Exit Door 205b>> In the second embodiment, the low oxygen room 2 has an entrance / exit door 205b as shown in FIG. The size of the entrance / exit door 205b is Dm 2 (Example: 2.0m 2 ), and the wall area of ​​the hypoxic room 2 (excluding the ceiling and floor) is Wm 2 (Example: 14.0m 2 ), W≦7×D, W≦6×D, W≦5×D may be satisfied.

[0128] There may be only one door 205b for users to enter and exit the hypoxic room 2. This makes it possible to maintain a stable hypoxic state in the hypoxic room 2 compared to when there are multiple doors 205b for users to enter and exit the hypoxic room 2.

[0129] <Low oxygen air supply opening 206> The hypoxic air supply opening 206 is provided with a louver 150 as a diffusion means for diffusing the hypoxic air. This can reduce the risk of the user directly inhaling the hypoxic air. The louver 150 can also be arranged when the hypoxic air supply opening 206 is provided on the ceiling. Note that, if it is desired to simplify the configuration, the installation of the louver 150 may be omitted.

[0130] "Chair 209" The low-oxygen room 2 according to this embodiment shown in Fig. 6 provides a space for relaxation. Chairs 209 or sofas, etc. are installed instead of stationary exercise equipment 204.

[0131] <Blindfold section> In the second embodiment, a screen of a predetermined height (e.g., 0.8 m, 1.2 m, 1.4 m) or more may be provided in the low oxygen room 2. The screen may be provided in the partition 208. This allows the user's privacy to be maintained. The screen may be, for example, an opaque material that makes it difficult to see inside the low oxygen room 2 from outside the low oxygen room 2, or an opaque material that makes it easy to see outside the low oxygen room 2 from inside the low oxygen room 2.

[0132] The screen may have a configuration in which the surface of a light-transmitting plate material is opaque and has a pattern with a light color on the outside and / or a dark color on the inside, and the illuminance inside the low-oxygen room 2 is lower than the illuminance outside the low-oxygen room 2. "Opaque" means that the visible light transmittance is a predetermined value (e.g., 50%, 30%, 10%) or less, "light color" means that the Munsell color system is 5 or more, preferably 7 or more, and "dark color" means that the Munsell color system is 5 or less, preferably 3 or less. The pattern may be a polka dot pattern or a houndstooth pattern. This makes it possible to reduce the sense of claustrophobia felt by users of the low-oxygen room 2 while maintaining the screen effect.

[0133] Furthermore, when a screen is provided, the lighting in the low oxygen room 2 may be placed at a predetermined height (e.g., 1.4 m, 1.2 m) or lower so that the light is not emitted upward. This can further enhance the screen effect.

[0134] <500 hypoxic facilities set up at 100 hypoxic training facilities> The hypoxic room 2 provided in the hypoxic facility 500 according to the second embodiment may be attached to a hypoxic training facility 100 intended for training such as exercise. The hypoxic room 2 may also be provided in a room with a hypoxic environment. For example, the hypoxic room 2 may be provided in a different hypoxic training room intended for training in a hypoxic environment. This can mitigate the effects of air exchange when entering and leaving the room.

[0135] Furthermore, when a low oxygen room 2 is provided in a facility that has a low oxygen training room where low oxygen training is performed, the low oxygen room 2 may be provided in a connected manner to the low oxygen training room. Connected means that the entrance / exit door 205b of the low oxygen room 2 faces the low oxygen training room, and the low oxygen room 2 can be entered from the low oxygen training room. Alternatively, entry to the low oxygen room 2 may be made by passing through an antechamber that serves as a low oxygen space. In this way, it is possible to suppress an increase in the oxygen concentration in the low oxygen room 2 that accompanies the opening and closing of the entrance / exit door 205b, and the low oxygen room 2 can be quickly brought to a low oxygen state.

[0136] When multiple hypoxic rooms 2 are provided, a supply path may be provided for supplying hypoxic air from the hypoxic air generator 30 to each hypoxic room 2, and the hypoxic air from the hypoxic air generator 30 may be branched and supplied. In this case, a flow control means such as a valve or an on-off valve whose opening degree can be adjusted may be provided in the supply path after branching. The information processing device 1 individually controls the oxygen concentration in each hypoxic room 2 based on the flow control means. For example, the information processing device 1 intensively hypoxics one of the hypoxic rooms 2.

[0137] <Control of hypoxic space constituent elements by information processing device 1> <Oxygen concentration control> The control unit 31 of the information processing device 1 controls the oxygen concentration in the low oxygen room 2 to, for example, 9.5 to 14.4% (equivalent to an altitude of 6000m to 3000m), preferably 11.7 to 13.4% (equivalent to an altitude of 4500m to 3500m), with an accuracy of ±1.0%, preferably ±0.5%.

[0138] When the low-oxygen room 2 is installed in a low-oxygen facility, the control unit 31 of the information processing device 1 sets the oxygen concentration in the low-oxygen room 2 to be 1.0 to 5.0%, preferably 2.0 to 3.0%, lower than the oxygen concentration in the low-oxygen training room where exercise is performed. This can enhance the effect of low-oxygen training and increase the feeling of refreshment when leaving the low-oxygen room 2.

[0139] Furthermore, the control unit 31 changes the oxygen concentration in the low-oxygen room 2 according to the user's condition (rest, yoga, stretching). For example, the oxygen concentration during stretching may be 0.5 to 3.0% higher than the oxygen concentration during rest, and preferably 1.0 to 2.0% higher. The oxygen concentration in the low-oxygen room 2 may be changed according to the user's profile (e.g., gender, years of experience, basic physical strength, occupation, hobbies). For example, the oxygen concentration for a person who enjoys mountain climbing should be 9.5 to 11.7% (equivalent to an altitude of 6000 to 4500 m), and the oxygen concentration for a beginner should be 11.7 to 14.4% (equivalent to an altitude of 4500 to 3000 m).

[0140] <Temperature control> The control unit 31 of the information processing device 1 controls the temperature of the low oxygen room 2 to, for example, a temperature range of 5.0 to 40.0° C. Alternatively, the control unit 31 sets a temperature range according to a high altitude environment corresponding to the set oxygen concentration and altitude.

[0141] In the low-oxygen room 2 of this embodiment, the control unit 31 sets two types: a cold region type and a sauna type. The cold region type low-oxygen room may be a standing type or a sauna type, but the standing type is preferable. The sauna type low-oxygen room may be a standing type or a sauna type, but the sauna type is preferable. The control unit 31 controls the temperature of the cold region type to -5 to 20°C, preferably 0 to 15°C, and more preferably 5 to 10°C. The control unit 31 controls the temperature of the sauna type to 20 to 50°C, preferably 25 to 45°C, and more preferably 30 to 40°C. The sauna type low-oxygen room 2 and the cold region type low-oxygen room 2 may be provided in parallel in the low-oxygen facility 500. By providing them in parallel, an effect similar to that of a sauna and a cold water bath can be obtained. In the case of providing them in parallel, the sauna type low-oxygen room 2 and the cold region type low-oxygen room 2 may be located adjacent to each other, and the control unit 31 may control the temperature based on heat exchange. The heat exchange may be of a type that does not have a moving part, such as a Peltier element.

[0142] (summary) As described above, the hypoxic room 2 of the second embodiment is equipped with at least the hypoxic air supply opening 206, the partition 208, and the entrance / exit door 205b. The floor area of ​​the hypoxic room 2 is (2.0×N) m when the capacity is N people. 2 The following is the result. This realizes a space-saving low-oxygen room 2 that can be differentiated from conventional low-oxygen training rooms. Also, unlike a general gym, it has the feature that no facility management staff is required in the low-oxygen space. Since the low-oxygen room 2 is small, the control unit 31 of the information processing device 1 can efficiently achieve the target low-oxygen concentration. In addition, the freedom of the installation location of the low-oxygen room can be increased, and for example, the low-oxygen facility 500 can be installed in a shop, a station or station premises, an office, a roadside like a vending machine, a part of a low-oxygen training room, etc. The low-oxygen room 2 of this embodiment is a completely different concept from the low-oxygen training room of the conventional technology in terms of the purpose of use and the operation method. That is, a reverse idea was obtained in which no stationary exercise equipment was installed in the low-oxygen room 2 that realizes a low-oxygen environment. As a result, it is not necessary to secure space, and a compact low-oxygen room 2 is realized. In addition, such a low-oxygen room 2 can obtain an unexpected synergistic effect that the low-oxygen air generating device 30 can also be made compact.

[0143] (Other embodiments) Although an embodiment of the present invention has been described above, the present invention is not limited to the above-described embodiment, and modifications, improvements, etc. within the scope that can achieve the object of the present invention are included in the present invention.

[0144] Also, for example, the above-mentioned series of processes can be executed by hardware or software. In other words, the above-mentioned functional configuration is merely an example and is not particularly limited. That is, it is sufficient that the information processing system S is provided with a function capable of executing the above-mentioned series of processes as a whole, and the type of functional block used to realize this function is not particularly limited to the above-mentioned example.

[0145] In addition, the location of the functional block is not particularly limited and may be arbitrary. For example, the functional block of the information processing device 1 may be transferred to another device, or the functional block of the other device may be transferred to a server. In addition, one functional block may be configured as a single piece of hardware, a single piece of software, or a combination of both.

[0146] When a series of processes is executed by software, a program constituting the software is installed in a computer or the like from a network or a recording medium. The computer may be a computer built into dedicated hardware. The computer may also be a computer capable of executing various functions by installing various programs, such as a server, a general-purpose smartphone, or a personal computer.

[0147] The recording medium containing such a program may be configured not only as a removable medium (not shown) distributed separately from the device main body in order to provide the program to the user, etc., but also as a recording medium etc. provided to the user in a state in which the medium is pre-installed in the device main body. Since the program can be distributed via a network, the recording medium may be mounted on or accessible to a computer connected or connectable to the network.

[0148] In the first and second embodiments described above, the information processing device 1 controls the hypoxic air generating device 30, the hypoxic space components, etc. As another control example, an embodiment in which the hypoxic air generating device 30 and the hypoxic space components each function independently is also effective. For example, the hypoxic air generating device 30 is connected to an air monitoring device 201 specialized in measuring oxygen concentration. The hypoxic air generating device 30 is then autonomously controlled so that the oxygen concentration is a preset value, for example, 15%. This control can be performed by an information processing device provided in the hypoxic air generating device 30, and ON / OFF control by an electronic circuit is also possible, in which a switch is turned on when the oxygen concentration exceeds 15% and turned off when the oxygen concentration falls below 15%.

[0149] In other words, the hypoxic room 2 and the hypoxic training facility 100 to which the present invention is applied can take various embodiments having the following configurations.

[0150] (1-1) That is, the hypoxic room (e.g., hypoxic room 2 in FIG. 1) is a hypoxic room for training in a hypoxic state, and is equipped with, as hypoxic space components (e.g., hypoxic space components in FIG. 1), indoor air exhaust means (e.g., indoor air exhaust opening 205 in FIG. 1) for exhausting air from within the hypoxic room, hypoxic air supply means (e.g., hypoxic air supply opening 206 in FIG. 1) for supplying air with a low oxygen concentration into the hypoxic room, and air monitoring means (e.g., air monitoring device 201 in FIG. 1) for monitoring the oxygen concentration of the air in the hypoxic room, and the air monitoring means in the hypoxic room is located at a lower height from the floor than the hypoxic air supply means. This makes it possible to efficiently exhaust carbon dioxide from within the hypoxic room 2 and supply hypoxic air to the hypoxic room 2. The arrangement and functions of the components of the hypoxic space are optimized compared to conventional techniques, health accidents caused by hypoxic conditions are prevented, and a hypoxic room and hypoxic training facility are provided in which users can safely carry out simulated high altitude training.

[0151] (1-2) The hypoxic room may further include one of a display device (e.g., display device 203 in FIG. 1) that displays the results of air monitoring by the air monitoring means, and an air conditioner (e.g., air conditioner 202 in FIG. 1) that circulates air within the hypoxic room. As a result, information such as the user's SpO2 and heart rate, information causally related to biological information, etc. are displayed on the display device 203. The temperature of the hypoxic room 2 can be controlled by the air conditioner 202. By controlling the temperature, a comfortable hypoxic environment is realized. In addition, a hypoxic environment at high altitudes where the temperature is lower than on the ground is reproduced.

[0152] (1-3) In the hypoxic room, the air monitoring means may further monitor the carbon dioxide concentration. This more reliably prevents adverse effects on the user caused by high carbon dioxide concentrations.

[0153] (1-4) The hypoxic training facility may include the hypoxic room and a machine room (e.g., machine room 3 in FIG. 1) having a hypoxic air generator (e.g., hypoxic air generator 30 in FIG. 1) that generates air with a low oxygen concentration. As a result, the oxygen concentration in hypoxic room 2 is accurately and stably controlled by the hypoxic air supplied from hypoxic air generator 30. In addition, hypoxic air generator 30 can be placed in a space different from hypoxic room 2. Therefore, it is possible to effectively prevent the high oxygen air discharged from hypoxic air generator 30 when generating hypoxic air from affecting hypoxic room 2.

[0154] (1-5) In a hypoxic training facility, the hypoxic air generator has a function of separating atmospheric air into hypoxic air and hyperoxic air, and supplies the hypoxic air to the hypoxic room through the hypoxic air supply means. The outlet for the hyperoxic air discharged from the hypoxic air generator (e.g., outlet 301 in the figure) should be located at a height of 1.8 m or more from the floor. Since oxygen-rich air is exhausted, it is dangerous to bring a fire close to it. In this regard, according to the configuration of this embodiment, the exhaust outlet 301 is set at a high position, making it difficult for people and fire to approach, thereby reducing the risk.

[0155] (1-6) In a hypoxic training facility, the hypoxic room may be equipped with an air conditioning device that circulates air within the hypoxic room, and may be equipped with an information processing device that controls at least one of the hypoxic air generating device, the air conditioning device, the indoor air exhaust means, and the hypoxic air supply means. This allows the information processing device 1 to appropriately set the oxygen concentration in the low oxygen room 2 depending on the purpose or use of the user.

[0156] (1-7) In the hypoxic training facility, the information processing device is placed in a control room (for example, control room 4 in FIG. 1) that is provided separately from the hypoxic room. This allows the manager to manage the low oxygen room 2 without being affected by the low oxygen environment. Also, by separating the control room 4 and the machine room 3, it is possible to prevent the manager from being affected by high oxygen air. As a result, even if an accident caused by low oxygen occurs, the operation of the information processing device will not be affected by the low oxygen, and the information processing device can be operated in a place where the oxygen concentration is normal. As a result, the accident can be kept to a minimum.

[0157] (2-1) A hypoxic room (e.g., hypoxic room 2) that forms a space in a hypoxic state, comprising, as hypoxic space components, at least an entrance / exit door (e.g., indoor air exhaust opening 205) for users of the hypoxic room to enter and exit the room, and a hypoxic air supply opening (e.g., hypoxic air supply opening 206) through which air with a low oxygen concentration is supplied into the hypoxic room, and the floor area of ​​the hypoxic room is (2.0×N) m when the capacity is N persons. 2 Below is a low oxygen room. This makes it possible to provide a space-saving low-oxygen room and low-oxygen facility that can be differentiated from conventional low-oxygen training rooms.

[0158] (2-2) The hypoxic room may further include, as a component element of the hypoxic space, an air conditioner (for example, air conditioner 202) that circulates air within the hypoxic room. This allows the temperature of the low-oxygen room 2 to be controlled by the air conditioner 202. By controlling the temperature, a comfortable low-oxygen environment is realized. Also, a low-oxygen environment at high altitudes where the temperature is lower than on the ground is reproduced.

[0159] (2-3) The hypoxic room may further include, as a component element of the hypoxic space, an air monitoring means (for example, air monitoring device 201) for monitoring the oxygen concentration and / or carbon dioxide concentration. Carbon dioxide can be efficiently exhausted from within the low oxygen room 2 and low oxygen air can be efficiently supplied to the low oxygen room 2.

[0160] (2-4) The hypoxic room may further include, as a constituent element of the hypoxic space, a display device (for example, display device 203) that displays the results of air monitoring by the air monitoring means. As a result, information such as the user's SpO2 and heart rate, and information causally related to the monitored human body mass, etc. are displayed on the display device 203. The temperature of the hypoxic room 2 can be controlled by the air conditioner 202. By controlling the temperature, a comfortable hypoxic environment is realized. In addition, a hypoxic environment at high altitudes where the temperature is lower than on the ground is reproduced.

[0161] (2-5) A hypoxic facility (eg, hypoxic facility 500) is a hypoxic facility equipped with a hypoxic room and a hypoxic air generator (eg, hypoxic air generator 30) that generates air with a low oxygen concentration. As a result, the oxygen concentration in the hypoxic room 2 is accurately and stably controlled by the hypoxic air supplied from the hypoxic air generator 30.

[0162] (2-6) The hypoxic facility may further include an information processing device (e.g., information processing device 1) that controls at least one of the hypoxic air generating device, the air conditioning device, the indoor air exhaust opening, and the hypoxic air supply opening. This allows the information processing device 1 to appropriately set the oxygen concentration in the low oxygen room 2 depending on the purpose or use of the user.

[0163] (2-7) In a hypoxic facility, the information processing device may be placed in a control room (for example, control room 4) that is provided separately from the hypoxic room. This allows the manager to manage the low oxygen room 2 without being affected by the low oxygen environment. Also, by separating the control room 4 and the machine room 3, it is possible to prevent the manager from being affected by high oxygen air. As a result, even if an accident caused by low oxygen occurs, the operation of the information processing device will not be affected by the low oxygen, and the information processing device can be operated in a place where the oxygen concentration is normal. As a result, the accident can be kept to a minimum. [Explanation of symbols]
