Description

  The present invention relates to a high-pressure and low-pressure room having a living space in which the atmospheric pressure in the room can be maintained at a pressure higher and lower than normal pressure.

  Conventionally, high-pressure oxygen therapy and high-altitude training have been performed by setting the atmospheric pressure in the room to be higher and lower than normal pressure. Various chambers that are high-pressure and low-pressure rooms for this purpose have been proposed. For example, the transforming chamber of US Pat. No. 6,057,099 seals a substantially airtight enclosure having a sufficient volume to enclose a patient, a sealable opening adapted to provide access to the enclosure, and the sealable opening. A closing mechanism adapted for this purpose, a reversible compressor fluidly connected to the inlet of the enclosure, and an outlet flow regulating device fluidly connected to the outlet of the enclosure.

  In the conventional transformation chamber of Patent Document 1, the pressure in the enclosure is varied by one reversible compressor provided outside the enclosure. In addition, air is taken into the enclosure by an outlet flow rate adjusting device having a valve structure fluidly connected to the outlet of the enclosure.

Special table 2010-517706

  However, in the conventional transformer chamber, the atmospheric pressure in the transformer chamber is controlled by one of the reversible compressors provided outside the enclosure and fluidly connected to the inlet of the enclosure, so fine control of the atmospheric pressure is difficult. It is a structure that is not suitable for fine control that links the operation and pressure with other devices installed inside the enclosure.

  The present invention has been made in view of such circumstances, and when performing training while reproducing high altitude environments in sports and mountain climbing, fine control of atmospheric pressure is possible, and the atmospheric pressure and exercise load are closely linked. It is to provide a high pressure and low pressure room.

  The high-pressure and low-pressure room according to claim 1 is a chamber that forms a living space, a pressurizing means that is disposed outside the chamber and increases the atmospheric pressure in the chamber, and is disposed within the chamber to lower the atmospheric pressure in the chamber. Pressure reducing means, an exercise load device disposed in the chamber and applying an exercise load to the exerciser by a mechanical operation, and a control means for controlling the operation of the exercise load device and a change in atmospheric pressure in the chamber in conjunction with each other. It is characterized by providing.

  The high pressure and low pressure room according to claim 2 is controlled by the control means so that the altitude change and the undulation change in the outdoor natural environment are simulated by the change in the exercise load by the exercise load device and the change in the atmospheric pressure in the chamber. And is characterized by applying a load to the exerciser in the chamber.

  The high-pressure and low-pressure room according to claim 3 is an exercise load device, and applies an exercise load equivalent to bicycle running, walking or running to an athlete.

  The high-pressure and low-pressure room according to claim 4 is characterized in that the exercise load device is a bicycle ergometer, a treadmill, a cross trainer, or a stepper that places each foot separately and performs a walking motion.

  According to the invention of the present application, when training is performed while reproducing a high altitude environment in sports or mountain climbing, fine control of the atmospheric pressure is possible, and the atmospheric pressure and the exercise load can be closely linked.

  Hereinafter, embodiments of the present invention will be specifically described with reference to the drawings. FIG. 1 is an explanatory diagram showing an example of the configuration of a high-pressure and low-pressure room according to the present invention. FIG. 2 is an explanatory diagram showing an example of pressure control in the high-pressure and low-pressure room.

  The high-pressure and low-pressure room 1 in the figure is a living space and can maintain the atmospheric pressure in the chamber 10a, which is a room, at higher and lower pressures than normal pressure. A chamber 10 that forms a living space; a pressurizing compressor 20 that is a pressurizing means for increasing the air pressure in the chamber 10a; a decompression compressor 22 that is a depressurizing means for reducing the air pressure in the chamber 10a; The treadmill 50 provided in 10a and the control apparatus 40 are provided. Moreover, the pressure gauge 30 for monitoring the atmospheric pressure in the chamber 10a is also provided. The high pressure is up to about 1.5 atm, and the low pressure is up to about 0.6 atm.

  The chamber 10 is sized so that the body of the exerciser can be completely accommodated, can be installed in a state where an exercise load device such as a treadmill 50 described later can be used, and can be accommodated by a plurality of people as necessary. . The chamber 10 has a doorway (not shown) and has a structure in which the chamber 10a becomes a sealed space when the chamber 10 is closed.

  The pressurizing compressor 20 is a pressurizing unit for increasing the atmospheric pressure in the chamber 10a, and is disposed outside the chamber 10 and communicates with the chamber 10a. The pressurizing compressor 20 is an example of a pressurizing unit, and may be another unit such as a pump.

  The decompression compressor 22 is decompression means for lowering the atmospheric pressure in the chamber 10a, and is arranged in the chamber 10 to push out air in the chamber 10a. The decompression compressor 22 is an example of decompression means, and may be other means such as a pump.

  Although not shown, various valve structures may be provided to adjust the atmospheric pressure in the chamber 10a.

  The treadmill 50 is an example of an exercise load device that applies exercise load to an exerciser by a mechanical operation, and the treadmill 50 itself is a device for walking and running indoors. In the present embodiment, the treadmill 50 is shown as an example of an exercise load device. However, the treadmill 50 may be a bicycle ergometer, a cross trainer, or a stepper that places each foot separately and performs a walking motion. It is not limited by the type of load device. Further, the type of exercise load given to the exerciser is not limited to walking or running on which the exercise load is applied by the treadmill 50 but also includes bicycle riding and the like, and is not limited by the content of the exercise load.

  The control device 40 is a control means for controlling the operation of the treadmill 50, which is an exercise load device, and the change in the atmospheric pressure in the chamber 10a in conjunction with each other, and includes a pressurizing compressor 20, a decompressing compressor 22, a pressure gauge 30, and a treadmill. Connected to the red mill 50 to control it. The control device 40 is electronically controlled using hardware or software.

  Next, operation | movement of the high voltage | pressure low pressure room 1 in this Embodiment is demonstrated (refer FIG. 2). First, a method for changing the atmospheric pressure in the chamber 10a will be described. In order to increase the pressure in the chamber 10a, the pressurizing compressor 20 is operated from a normal pressure state (atmospheric pressure on a flat ground) to pressurize the chamber 10a. Then, when the desired atmospheric pressure is reached, the operation of the pressurizing compressor 20 is stopped. Next, when the pressure in the chamber 10a is lowered, the decompression compressor 22 is operated to push the air in the chamber 10a out of the chamber 10 or to open a valve structure (not shown) to a high pressure. The discharged air is discharged out of the chamber 10.

  In addition, even if the valve structure is simply opened to return to the normal atmospheric pressure state in the chamber 10a in a high pressure state, if the pressure in the chamber 10a approaches the normal atmospheric pressure state, the valve structure is simply opened. Then, a situation occurs in which the atmospheric pressure in the chamber 10a cannot be lowered. In such a case, the decompression compressor 22 is operated so as to actively expel the air in the chamber 10a so that the atmospheric pressure in the chamber 10a is brought to a normal atmospheric pressure state.

  In addition, when it is desired to efficiently lower the atmospheric pressure in the chamber 10a having a high pressure, the pressure in the chamber 10a can be more efficiently lowered by using the decompression compressor 22.

  Next, a case will be described in which the operation of the treadmill 50, which is an exercise load device, is controlled in conjunction with the change in the atmospheric pressure in the chamber 10a. Specifically, for example, under the control of the control device 40 which is a control means, the altitude change and the undulation change in the outdoor natural environment are changed, the exercise load applied by the treadmill 50 is changed, and the atmospheric pressure in the chamber 10a is changed. This is a case where the load is applied to the exerciser in the chamber 10a. In this case, as shown in FIG. 2, for example, when it is desired to create an environment in which the chamber 10a is viewed as a mountain with a high altitude, first, the decompression compressor 22 is used in consideration of the increase in altitude. Then, the pressure in the chamber 10a is lowered. Thereby, it will be in the state which can reproduce the environment of the atmospheric pressure of a predetermined altitude. Then, as the altitude rises, an exercise load is applied to the exerciser along the change in altitude by the operation of the treadmill 50.

  Thereafter, for example, when it is desired to reproduce an environment in which the altitude is slightly lowered (in a state where the atmospheric pressure is slightly increased), the pressurizing compressor 20 is operated so that the atmospheric pressure in the chamber 10a is reduced to a desired atmospheric pressure. It is made higher (in FIG. 2, it is described as “relaxation”). The operation of the treadmill 50 also adjusts the exercise load on the exerciser according to the change in altitude where the altitude is decreasing. When it is desired to repeatedly reproduce the up and down of the mountain, as shown in FIG. 2, the decompression compressor 22 and the pressurization compressor 20 may be operated so as to repeat decompression and relaxation. Further, the treadmill 50 is also operated so as to have an exercise load that repeatedly reproduces the ascending and descending of the mountain. Finally, when the chamber 10a is brought into a normal atmospheric pressure state (atmospheric pressure on a flat ground), the pressurizing compressor 20 is operated, and the treadmill 50 is also ended.

  According to the high pressure / low pressure room 1 according to the present embodiment having the above-described structure, the pressurizing compressor 20 as the pressurizing means is provided outside the chamber 10, while the decompressing compressor 22 as the decompressing means is provided in the chamber 10a. It is possible to finely control the atmospheric pressure.

  When training is performed while reproducing the high altitude environment in sports or mountain climbing, fine control of the atmospheric pressure is possible, and the atmospheric pressure and the exercise load can be closely linked.

  As described above, according to the present invention, when performing training while reproducing a high altitude environment in sports or mountain climbing, it is possible to finely control the atmospheric pressure, and a high-pressure and low-pressure room in which the atmospheric pressure and the exercise load are closely linked. Can be provided.
