Description

  The present invention relates to a pressure regulating device that is optimal for performing an air bath, and further relates to a pressure regulating method for the pressure regulating device.

  An air bath is one method of preventing a disease by exposing the body to a specific air environment and training the body using the physical properties and chemical components of the air. Air baths have equally good effects on the regulation of blood circulation and on the tissue organs of the human body. Trace elements, inorganic salts, oxygen, etc. in the air can improve the vitality and immune function of the organism, and absorbing fresh air and improving the oxygen content in the blood protects cardiopulmonary function It is said that it will be a very effective aid.

  In order to train the body by adopting an air bath, mainly stimuli formed by the difference between the air temperature (air temperature) and the body temperature are used. Cold changes in temperature activate the body's thermoregulatory function, the cerebral cortex and the reflex center of vasomotion, and can be well trained. For example, cold air stimulation causes blood vessels on the surface of the body to contract, causing blood to flow toward the viscera. Conversely, warm air stimulation dilates blood vessels on the surface of the body and causes blood to flow toward blood vessels on the surface of the body. Moreover, the air bath is expected to have a stress relieving effect not only in humans but also in animals.

  On the other hand, there has been proposed an air bath device that exposes the skin to air activated by a far-infrared emitter while warming hands or feet with air (see, for example, Patent Document 1).

  INDUSTRIAL APPLICABILITY According to the present invention, it is possible to obtain a pressure regulating device that is optimal for giving a subject a uniform and accurate temperature change for performing an air bath. In addition, there is an effect that it is possible to obtain a pressure regulation method that performs an air bath that gives a uniform and accurate temperature change to the subject.

It is a front view which shows the structure of one Example of the pressure regulating device of this invention. It is a top view of FIG. It is a side view of FIG. FIG. 2 is a flowchart showing driving of the control device of FIG. 1, FIG. A is a flowchart showing a pressure reducing step, and FIG. It is a diagram which shows the result of having measured the temperature change in an airtight part at the time of repeating a pressure reduction process and a pressurization process. It is a diagram which shows another result which measured the temperature change in an airtight part at the time of repeating a pressure reduction process and a pressurization process.

In the present invention, an airtight portion that can be airtight, a decompression pump that communicates with an exhaust port of the airtight portion to reduce the air pressure in the airtight portion, and an excessive pressure reduction in which the air pressure in the airtight portion falls below a predetermined threshold pressure. A pressure regulating device including an over-decompression preventing device for preventing
Further comprising a decompression control means for controlling the decompression pump;
The depressurization control means repeatedly controls at least once within a predetermined time between a depressurized state equal to or higher than the threshold pressure and a normal pressure or a broad normal pressure state that is higher than the depressurized state and lower than the normal pressure. Is.

  The pressure regulating device according to the present invention includes an airtight portion that can be airtight, a decompression pump that communicates with an exhaust port of the airtight portion and reduces the pressure in the airtight portion, and the air pressure in the airtight portion is lower than a predetermined threshold pressure. What is necessary is just to be provided with the excessive pressure reduction prevention apparatus which prevents that it becomes an excessive pressure reduction. In addition, the airtight part in this invention is not assumed when pressurizing more than a normal pressure (atmospheric pressure). This is because the hermetic part does not function as a pressurized container.

  The airtight part of the present invention includes an airtight part capable of withstanding pressure change between a reduced pressure state equal to or higher than a threshold pressure and a normal pressure or a broad normal pressure state that is higher than the reduced pressure state and lower than the normal pressure. If it is. The material constituting the hermetic portion may be any material that maintains airtightness and can withstand the pressure change between the reduced pressure state and the wide range normal pressure state, and is made of metal, resin, wood or the like alone or in combination. The

  Further, the shape of the airtight portion may be any shape as long as it maintains airtightness and can withstand the pressure change between the reduced pressure state and the wide range normal pressure state. Since it is not low, there is no restriction on its shape as long as airtightness is maintained. For example, if a rectangular panel is combined and the airtightness of a joint part can be ensured, it may be configured as a hexahedral casing.

  The decompression pump of the present invention may be any decompression pump that can bring about a sudden decompression change that causes adiabatic expansion, such as a rotary pump (oil rotary pump), an oil diffusion pump, a turbo molecular pump, an ion pump, a dry pump. A decompression pump such as a pump or a canal booster pump can be used alone or in combination of one or more.

  The over-decompression preventing device of the present invention may be any device that prevents the pressure of the hermetic part from being over-depressurized below a predetermined threshold pressure, and automatically when the pressure of the hermetic part falls below the threshold. Or what provided the open valve forcibly opened in the communicating pipe which connects external air and an airtight part is mentioned.

  As a safety device separate from this over-depressurization prevention device, a pressure-regulating device that supplies an outside air amount that is less than the amount of air exhausted from the air-tight portion by a decompression pump, or a subject who entered the air-tight portion feels abnormal and the air-tightness Preferably, a double or triple safety device such as an open valve that is operated from the inside to release the airtight state is further provided.

  The threshold atmospheric pressure of the present invention varies among individuals, and the atmospheric pressure threshold varies depending on a healthy person or a person suffering from a disease. In addition, the threshold can be lowered by experience, and conversely, the threshold may be increased by physical condition. In general, a pressurized cabin in an aircraft has an atmospheric pressure state (about 780 hPa) at an altitude of 2000 m at an altitude of 12000 m and can be used even by a person suffering from a disease. Accordingly, the threshold value of a general healthy subject is at least 600 hPa, which is over an altitude of 2000 m and an altitude of about 4200 m or less.

  The decompression control means in the present invention may be any means that repeatedly controls the atmospheric pressure cycle that changes between the decompression state and the broad normal pressure state one or more times within a predetermined time. The depressurized state refers to a depressurized state that is equal to or higher than a threshold pressure, and the value of the depressurized state is also changed according to a healthy person or a sick person. For example, the reduced pressure state is an atmospheric pressure of an altitude of 1000 m, the wide normal pressure state is an atmospheric pressure of an altitude of 200 m, and the pressure change between the reduced pressure state and the wide normal pressure state is repeated.

  It should be noted that the repeated reduced pressure state may be a reduced pressure equal to or higher than the threshold pressure and may not be the same pressure. For example, the first reduced pressure state may be a different reduced pressure state such as 780 hPa corresponding to an altitude of 2000 m and the second reduced pressure state may be 700 hPa corresponding to an altitude of 3000 m. Similarly, the repeated normal atmospheric pressure state may be normal pressure or an atmospheric pressure higher than the immediately preceding reduced pressure state and lower than the normal pressure, and may not be the same atmospheric pressure. For example, the first wide normal pressure state may be a normal pressure (1013 hPa), and the second wide normal pressure state may be a different atmospheric pressure state such as 989 hPa corresponding to an altitude of 200 m.

  In addition, in a high altitude environment such as Mexico City, the installation place of the pressure regulator of the present invention preferably includes a pressurizing device for normal pressure (1013 hPa) and an altitude of 200 m (989 hPa). However, it does not pressurize beyond normal pressure. This is because in the case of pressurization exceeding the normal pressure, the airtight part itself needs to adopt a configuration as a pressurization container.

  The change in the atmospheric pressure cycle of the present invention is expanded or compressed at a speed at which the subject can perceive that the temperature in the hermetic portion decreases or increases due to heat generated by cooling or adiabatic compression by adiabatic expansion. Specifically, by changing from a reduced pressure state to a wide normal pressure state, or from a wide normal pressure state to a reduced pressure state in 1 to 60 minutes, a temperature change caused by heat generation by cooling or adiabatic compression by adiabatic expansion is caused to the subject. I can be aware. For example, when the atmospheric pressure (about 900 hPa) is changed from normal pressure (about 1013 hPa) to an atmospheric pressure (about 900 hPa) corresponding to an altitude of 1000 m, the temperature of 19.9 ° C. changes to 17.0 ° C. Subsequently, when the altitude is changed to 200 m (about 989 hPa) in 1.5 minutes, the temperature of 17.0 ° C. changes to 20.1 ° C.

  On the other hand, for example, even if it is gradually changed from the wide normal pressure state to the reduced pressure state or from the reduced pressure state to the wide normal pressure state over a long time of 60 minutes, for example, the temperature in the airtight portion changes slightly. . In particular, when the outside air is naturally sucked into the airtight portion by the oxygen deficiency preventing means as described later, the temperature of the airtight portion is surely changed.

  The change in the temperature of the hermetic part accompanying the change in atmospheric pressure between the reduced pressure state and the wide range normal pressure state is due to the fact that the air that expands or contracts in the hermetic part itself cools or generates heat. The temperature change and the temperature change due to the radiant heat hitting the subject are completely different in nature and give the subject a temperature change closer to the natural air bath to the subject in the airtight part, which is optimal for performing an air bath. A pressure regulator can be obtained.

  As for the size of the hermetic portion and the capacity of the vacuum pump, it is possible to bring about a sudden pressure change that causes adiabatic expansion, and the volume that can quickly change the pressure between the reduced pressure state and the wide normal pressure state. That's fine. In an airtight part with a large capacity, it is sufficient to provide one or more decompression pumps with a large capacity and supply at least one air supply means with a large capacity for the airtight part. In this case, the device itself does not have to be large. As a large airtight part, it is possible to realize a room with a capacity that allows several people to bathe at the same time. Moreover, as a small airtight part, the airtight part of a capacity | capacitance of the grade which one person lies down is raised. Furthermore, an airtight part with a small capacity that can accommodate pets such as dogs and cats is also possible.

  In any case, in order to supply a subject with an air bath using stimulation due to a temperature difference, it is preferable to hold at least the entire body inside. Therefore, as the airtight part of the present invention, the entire human body is held inside. Specifically, the airtight part holds the entire human body inside, and the airtight part is configured as a room where all the human body enters, and the subject enters the airtight room and repeats the pressure change between the reduced pressure state and the wide normal pressure state. . In this case, oxygen deficiency prevention means for preventing oxygen deficiency in the hermetic portion is further provided.

  As an oxygen deficiency prevention means of the present invention, an intake pipe for introducing outside air below the displacement of the decompression pump into the airtight part is installed so that the outside air is naturally sucked according to the air pressure in the airtight part, or automatically at the time of power failure, etc. For example, a door or a vent opening that is opened to prevent oxygen deficiency in the airtight part. By this oxygen deficiency prevention means, outside air is naturally sucked into the pressure-tight airtight portion.

  Due to the natural intake of this outside air, the outside air sucked into the airtight portion is introduced into the airtight portion by adiabatic expansion when it is introduced into the airtight portion. Gradually rises. On the other hand, when the pressure is applied to a wide range of normal pressures, the temperature in the hermetic portion rises from the initial outside temperature by increasing the temperature in the reduced pressure state. Note that, as described above, the heat generated by this pressurization is completely different from the temperature change caused by warm air and the temperature change caused by radiant heat, because the air in the airtight part itself generates heat uniformly.

In the present invention related to the method, an airtight part capable of airtightness, a decompression pump communicating with the exhaust port of the airtight part to reduce the pressure inside the airtight part, and the air pressure of the airtight part being lower than a predetermined threshold pressure A pressure regulating method for a pressure regulating device provided with an over-decompression preventing device for preventing over-decompression,
A pressure reducing step of reducing the air pressure in the hermetic portion to a reduced pressure state equal to or higher than the threshold pressure and lowering the air temperature in the airtight portion by adiabatic expansion; and from the reduced pressure state to normal pressure or higher than the reduced pressure state and lower than normal pressure By repeating the pressurizing step of pressurizing to a wide range of normal pressures and restoring the temperature in the airtight part to be higher than the temperature of the original airtight part at least once within a predetermined time, A decompression pump that communicates with the exhaust port of the hermetic part and depressurizes the air pressure in the hermetic part, and an over-depressurization prevention device that prevents the air pressure of the hermetic part from becoming an over-decompression pressure lower than a predetermined threshold pressure. The pressure regulator provided can be regulated.

  As for the pressure regulator in the present invention related to the method, similar to the above-described pressure regulator, an airtight portion that can be airtight, a pressure reducing pump that communicates with an exhaust port of the airtight portion and reduces the pressure in the airtight portion, and It is only necessary to include an over-depressurization prevention device that prevents the air pressure in the airtight part from becoming an over-decompression pressure that is lower than a predetermined threshold pressure. Street.

  In the present invention, a pressure reducing step for reducing the air pressure in the airtight portion to a reduced pressure state equal to or higher than the threshold pressure and lowering the air temperature in the airtight portion by an adiabatic expansion action, and normal pressure from the reduced pressure state to a normal pressure higher than the reduced pressure state. The pressurizing step of pressurizing to a lower pressure range and restoring the temperature in the airtight part to be higher than the temperature of the original airtight part may be repeated at least once within a predetermined time. Specifically, it may be controlled by including a decompression control means for controlling the decompression pump in the pressure regulating device described above, and the operator changes the atmospheric pressure in the hermetic part while checking the barometer in the hermetic part. Including that.

  FIG. 1 is a front view showing the configuration of an embodiment of the pressure regulating device of the present invention. FIG. 2 is a plan view of FIG. FIG. 3 is a side view of FIG. As shown in the figure, the pressure adjusting device 10 of the present embodiment includes an airtight portion 11 composed of a plurality of panel plates 30, and a decompression pump 13 communicating with an exhaust pipe 12 having one end opened inside the airtight portion 11. A filter 15 is attached to the outside of the airtight part 11 at the other end of the air supply pipe 14 whose one end is opened at a position facing the exhaust pipe 12 in the airtight part 11.

  The external appearance of the airtight part 11 is a housing composed of a plurality of panel plates 30 having substantially the same size. In this embodiment, it is composed of 14 panel plates. On the front and back (not shown), an entrance / exit panel 31 having an airtight door 32 provided with two windows 33 at the center is used. Three side panels 34 each having two windows 33 are connected and used on both side surfaces. Three ceiling panels 35 are connected to the ceiling surface. In the same manner as the ceiling surface, three floor panels 36 are connected to the floor surface.

  Although not shown, each panel plate 30 has a rim portion standing so as to surround four sides of the rectangle, and the panel plates adjacent to each other through the panel plates 30 or a joining member by the rim portion. 30 is connected. By connecting an elastic rubber plate between the rim portions of the panel plates 30 to be joined or between the rim portion of the panel plates and the joining member, airtightness between the connecting portions is maintained.

  An air supply pipe 14 is arranged on one side of the front entrance panel 31, and a pressure control valve 16 is attached in the middle of the air supply pipe 14 to adjust the pressure loss caused by the opening degree of the pressure control valve 16. As a result, the outside air that has passed through the filter 15 is naturally sucked continuously in accordance with the atmospheric pressure in the airtight portion 11. The opening degree of the pressure control valve 16 is performed by a control device 22 described later. Note that the pressure control valve 16 has a structure that cannot be completely closed, thereby functioning as an oxygen deficiency prevention means.

  An exhaust pipe 12 is arranged on the other side of the front entrance panel 31. An exhaust solenoid valve 17 is attached in the middle of the exhaust pipe 12, and a branch pipe 18 and an outside air are provided on the decompression pump 13 side. An over-decompression prevention pipe 20 that communicates with the outside air via the electromagnetic valve 19 is arranged. Further, the airtight portion 11 is provided with a number of pressure sensors 21 for measuring the internal air pressure. When the air pressure in the airtight portion 11 falls below a preset threshold value due to some abnormality, the decompression pump 13 is stopped. Then, when the outside air solenoid valve 19 is opened and outside air is sucked in, excessive decompression can be prevented.

  A control device 22 as a decompression control means for controlling the drive of the decompression pump 13 is disposed above the decompression pump 13, and the numerical value of the pressure sensor 21 of the hermetic section 11 is also input to the control device 22, and the electromagnetic The drive of the valves 17 and 19 and the opening degree of the pressure control valve 16 are also controlled.

  FIG. 4 is a flowchart showing driving of the control device of FIG. 1, FIG. 4 a is a flowchart showing a pressure reducing process, and FIG. 4 b is a flowchart showing a pressurizing process. As shown in FIG. a, in the decompression step, the decompression pump 13 is driven by the control device 22. In this case, it goes without saying that the external electromagnetic valve 19 is closed and the exhaust electromagnetic valve 17 is opened.

  When the decompression pump 13 is driven, the opening of the pressure control valve 16 is set to the minimum opening so that rapid decompression is performed. The atmospheric pressure is periodically checked to determine whether the target pressure reduction value is set in advance. When the target pressure reduction value is reached, the pressure reduction pump 13 is stopped. When the decompression pump 13 is stopped, the exhaust solenoid valve 17 is closed to maintain the pressure inside the hermetic portion 11.

  Moreover, since the pressure control valve 16 has a structure that is not blocked, the pressure gradually increases when the drive of the decompression pump 13 is stopped. Therefore, in the case where the target decompression state is maintained for a long time, if the constant pressure rises with reference to the target pressure, the exhaust solenoid valve 17 is opened and the decompression pump 13 is driven again. Good.

  As shown in FIG. b, in the pressurizing step, the control device 22 opens the opening of the pressure control valve 16 to increase the air pressure in the airtight portion 11. The internal air pressure is regularly checked by the pressure sensor 21 of the airtight portion 11 to determine whether the target pressure value is set in advance, and the target pressure value (wide normal pressure state) is obtained. In that case, the opening of the pressure control valve 16 is squeezed to the minimum.

  Similarly, since the pressure control valve 16 has a structure that is not closed, the pressure gradually increases to the normal pressure even if the opening degree of the pressure control valve 16 is minimized. When maintaining a wide range of normal pressures lower than normal pressure for a long time, control is performed to open the exhaust solenoid valve 17 and drive the decompression pump 13 again when a certain pressure rises with reference to the target pressure. May be.

  In addition, in the room of the airtight part 11 of a present Example, you may provide the apparatus which makes test subject's room comfortable, such as illumination, an air-conditioner, floor heating, a CD player, and a television, as needed. In addition, about an air conditioner, it is necessary to ensure airtightness so that the drain in the room | chamber interior of an airtight part may be discharged | emitted indoors.

  The pressure reducing device according to the present embodiment is used to reduce the atmospheric pressure in the hermetic portion 11 to reduce the air temperature in the hermetic portion by adiabatic expansion, and from this reduced pressure state to a wide range normal pressure state lower than normal pressure. The change in the temperature in the airtight part was measured by repeating the pressurizing step of restoring the air temperature in the airtight part to be higher than the temperature of the original airtight part. The results are shown in Table 1.

  As shown in Table 1, it was confirmed that a temperature difference of 3 ° C. or more could be given to the subject who entered the hermetic part in several minutes, and that the stimulus due to a quick change in temperature could be given to the subject.

  Moreover, the result of having measured the temperature change in an airtight part at the time of repeating a pressure reduction process and a pressurization process in FIG.5 and FIG.6 is shown. In each figure, the solid line connecting the black circle points is the temperature (° C.) in the airtight portion, and the broken line connecting the black square points is the pressure (hPa) in the airtight portion.

  In FIG. 5, the depressurization step is from atmospheric pressure (1013 hPa) or atmospheric pressure corresponding to an altitude of 200 m (989 hPa) to atmospheric pressure corresponding to an altitude of 1000 m (900 hPa), and the pressurizing step is from atmospheric pressure corresponding to an altitude of 1000 m (900 hPa) to an altitude of 200 m. The corresponding atmospheric pressure (989 hPa) or normal pressure (1013 hPa) was repeated in 2.5 minutes. In FIG. 6, the depressurization step is from atmospheric pressure (1013 hPa) or an atmospheric pressure corresponding to an altitude of 200 m (989 hPa) to an atmospheric pressure corresponding to an altitude of 3000 m (700 hPa), and the pressurizing step is from an atmospheric pressure corresponding to an altitude of 3000 m (700 hPa) to an altitude of 200 m. The corresponding atmospheric pressure (989 hPa) or normal pressure (1013 hPa) was repeated in 6 minutes (8 minutes for the first and last pressure).

  As shown in FIG. 5, when the atmospheric pressure corresponding to an altitude of 200 m (989 hPa) or the atmospheric pressure in a wide range of normal pressures (1013 hPa) in the pressurizing step, the temperature is higher than the original outside air temperature (25 ° C.). It was confirmed that Moreover, it turned out that the temperature range of 23.6 degreeC-26.8 degreeC is repeated in 1 cycle 5 minutes.

  On the other hand, as shown in FIG. 6, when the atmospheric pressure corresponding to the altitude of 200 m (989 hPa) or the normal pressure (1013 hPa) is set to the atmospheric pressure in a wide range of normal pressure in the pressurizing step, as in FIG. It was confirmed that the temperature was higher than (26 ° C.). Moreover, it turned out that the temperature range of 21.5 degreeC-30.0 degreeC is repeated in 1 cycle 12 minutes.
