Description

  The present invention relates to a high-pressure / high-concentration oxygen formulation that supplies air containing high-concentration oxygen in a high-pressure state to the human body.

  A high-pressure / high-concentration oxygen prescription is known in which air containing high-concentration oxygen in a high-pressure state is supplied to the human body.

  More specifically, when air containing oxygen at a higher concentration (30% to 35%) than in the atmosphere is inhaled into the body, more oxygen than normal is bound to hemoglobin in red blood cells in the body. . On the other hand, in an environment where the atmospheric pressure is higher than that in the atmosphere (1.22 to 1.25 atmospheres), oxygen in the body dissolves more in the blood and lymph than in the atmospheric pressure state. As a result, the oxygen reaches the tips of the capillaries of the feet and fingertips, the heart, and the capillaries of the brain.

  In other words, high-pressure and high-concentration oxygen prescription means that the metabolism and activity of cells in every corner of the body is increased by realizing an environment of high-pressure oxygen in air containing high-concentration oxygen. It has a recovery effect and a mental relaxation effect. The high pressure / high concentration oxygen prescription is also expected to have an effect of improving various diseases.

  An oxygen supply system is used as a facility for performing such high pressure / high concentration oxygen prescription.

  This oxygen supply system includes a capsule that can be accommodated by one person and an oxygen supply device that supplies air containing high-concentration oxygen in the capsule.

  Here, comfort in the capsule during operation of the oxygen supply system is cited as one of important factors for a user who uses this oxygen supply system to sufficiently obtain the above-described effects. That is, while the oxygen supply system is in operation, it is considered that the above-described effects of the high-pressure / high-concentration oxygen prescription can be sufficiently obtained by spending in a relaxation state in which the user feels comfortable in the capsule. .

Then, by relaxing the release sound when the air supplied from the oxygen supply device is discharged from the supply / discharge port formed in the capsule and the wind pressure from the supply / discharge port, the environment is quiet to the user. Has been disclosed (for example, see Patent Document 1). With the technology according to this document, the user in the capsule can obtain a comfortable environment in which neither the emitted sound of the air nor the wind pressure is anxious, and the user can obtain a higher-quality relaxation state.
Utility Model Registration No. 3107625

  However, even if only the point relating to the sound and wind pressure in the capsule is improved by the above-mentioned patent document, the user may not be able to obtain the relaxation state due to other factors.

  Among the factors, the temperature in the capsule at the time of use can be cited as a major factor. That is, as described above, since the capsule is set to a limited volume that can be accommodated by one person, the body temperature of the user may be directly affected by the temperature in the capsule. When such a situation occurs, conventionally, only the method of cooling the air outside the capsule, that is, the air around the oxygen supply device in advance, or directly cooling the pipe supplying the air has been taken.

  Then, in the former method, the vicinity of the oxygen supply device, that is, the room where the oxygen supply system is installed becomes unnaturally cold, which is unnecessary for people other than the user in the capsule and the user before entering the capsule. Will be uncomfortable. In the latter case, even if the pipe itself is directly cooled, a large amount of air of, for example, 50 liters per second passes through the pipe from the oxygen supply device, so that it can come into contact with the area inside the pipe for a short time passing through the pipe. Only air was cooled, and the cooling effect was not sufficiently obtained.

  The present invention has been made paying attention to such problems, and a main object of the present invention is to provide a user with a comfortable environment in terms of temperature during operation of the oxygen supply system.

  In order to achieve such an object, the present invention takes the following measures. That is, the air cooling device according to the present invention accommodates a user and can form a sealed space maintained in a high-pressure state where the atmospheric pressure is higher than the atmospheric pressure, and supply air containing oxygen at a higher concentration than in the atmosphere. Is used in an oxygen supply system including an oxygen supply device that supplies oxygen into the capsule, a housing interposed between the oxygen supply device and the capsule, and the supply air in the housing And a low temperature part maintained at a low temperature, and a cooling part capable of releasing heat of the supply air to the low temperature part.

  In the air cooling method according to the present invention, supply air containing oxygen at a higher concentration than in the atmosphere is supplied to a capsule that can accommodate a user and constitute a sealed space, and the inside of the capsule is under atmospheric pressure. The present invention is applied to an oxygen supply system that maintains a high atmospheric pressure at a high atmospheric pressure, and introduces the supply air before being supplied to the capsule into the housing, and into the housing by the supply air introducing step. A cooling step for releasing the heat of the introduced supply air to a low-temperature portion provided in the housing and maintained at a lower temperature than the supply air; and the supply air for releasing heat by the cooling step. And an air supply step for supplying the air into the capsule.

  If such an apparatus or method is adopted, it is possible to effectively avoid an increase in temperature in the capsule due to a user's body temperature or the like. In addition, it is possible to effectively avoid a situation where the temperature outside the capsule must be lowered in advance.

  In order to achieve a quiet operation without using a motor or a fan and stably maintain the low temperature of the low temperature part, it is desirable that the low temperature part has a cold insulating material.

  Here, the cold insulation material is a sealed bag filled with a predetermined polymer, etc., which can be used as a substitute for ice by freezing in advance, and generally used for low-temperature storage of food and ice pillows Point to.

  As a specific configuration of the cooling unit that effectively lowers the temperature held by the supply air, one having a radiator can be mentioned.

  In order to stably maintain the temperature of the low temperature part, it is preferable to interpose a heat insulating material between the housing and the low temperature part. Various materials having a heat insulating effect can be applied to the heat insulating material, but by using a urethane material, not only a heat insulating effect but also an effect of protecting the cooling part in the housing can be achieved.

  And, in order to be able to be easily applied to different oxygen supply systems as a configuration in which the housing can be moved as appropriate, it is desirable to provide the housing with a transport means that can move the housing. Specific examples of the means include a handle, a handle, or a caster.

  Furthermore, in order to supply supply air to a plurality of capsules arranged at different locations, it is desirable to arrange a plurality of supply air discharge portions for discharging supply air in the housing.

  According to the air cooling device and the air cooling method of the present invention, it is possible to effectively avoid the temperature in the capsule from being increased due to the user's body temperature or the like, so that the temperature in the capsule is comfortable for the user. Cooling to a temperature can be effective, and the user can effectively contribute to obtaining a comfortable relaxation state.
