Description

Technical Field

[0001] The utility model relates to the field of health, in particular to a hydrogen-oxygen breathing system with an air storage bag. Background Art

[0002] Existing studies have proven that inhaling hydrogen has a positive effect on the brain, bronchi, lungs and muscles. Hydrogen instillation diffuses through the blood, so a clear effect on the whole body can be expected.

[0003] However, as a flammable and explosive gas, hydrogen has a large explosion hazard range: specifically, the mixing ratio of air and hydrogen is between 4.1% and 74.2%, and the mixing ratio of oxygen and hydrogen is between 3% and 93.3%. When there is a fire source within this explosion hazard range, the mixed gas is prone to safety risks such as detonation and deflagration.

[0004] The patent document with publication number CN107536685A discloses a dual-circulation system hydrogen-rich cell repair instrument, including a fumigation health cabin and a controller. The solution sets a hydrogen generator and a hydrogen-rich water machine inside the equipment room. The hydrogen generator is connected to the closed cabin through a hydrogen pipeline. The end of the hydrogen-rich water pipeline of the hydrogen-rich water machine is also connected to a mouth and nose mask. This solution adopts the design of "external steaming and internal inhalation". "External steaming" can reduce skin inflammation damage and accelerate skin inflammation repair; "internal inhalation" can quickly open up the metabolic system, and has a defensive and therapeutic effect on sub-health and chronic diseases. Hydrogen has antioxidant and strong reducing properties, effectively overcomes free radicals, and helps cell metabolism.

[0005] However, the above scheme has the following problems: 1. Since the solubility of hydrogen in water is very low, the hydrogen content in hydrogen-rich water is not high, and the amount of hydrogen that can be absorbed by the human body is relatively small, so its effect is very limited. 2. Hydrogen is directly filled into the closed cabin through a hydrogen pipeline, but it does not limit the safe concentration of hydrogen, which can easily put the hydrogen content in the closed cabin in an explosion-hazardous range. At the same time, this scheme not only has heat sources such as infrared heating plates in the closed cabin, but also needs to consider that the user's clothes are prone to static electricity, which may lead to hydrogen detonation or explosion in the closed cabin, which poses a very obvious safety risk.

[0006] On this basis, the patent document with publication number CN105163788A discloses a high-concentration hydrogen mixed gas breathing system, which uses a mask to provide a high-concentration hydrogen mixed gas, such as a hydrogen-air mixed gas or a hydrogen-oxygen mixed gas. However, this solution has the following problems: there is no corresponding gas storage device and one-way ventilation valve on the hydrogen and oxygen supply pipelines, and the supply of hydrogen and oxygen must be increased to meet the tidal volume of each breath of the human body. Relying on a power pump to continuously pump the hydrogen mixed gas into the mouth and nose mask, and forced ventilation is still performed when the human body's inhalation phase ends and turns to the exhalation phase, which does not conform to the normal respiratory physiological characteristics of the human body and causes discomfort to the user; the hydrogen mixed gas pumped during the human body's exhalation phase is discharged from the mask with the exhalation and cannot be used by the human body, which increases the loss of hydrogen mixed gas and the energy consumption of related equipment.

[0007] Further reference is made to the hydrogen-oxygen supply device described in the Korean invention patent publication with publication number "KR10-2022-0144426A", which pumps the hydrogen and oxygen generated by water electrolysis into a hydrogen storage unit and an oxygen storage unit respectively and connects them to a respirator through a closed air supply pipeline for human inhalation, and the gas exhaled by the human body is directly discharged through the exhaust part of the respirator. The scheme has the following technical problems: 1. Although the scheme adds a gas storage unit, its gas supply method still relies on the pressure of a power pump to supply gas, which does not conform to the normal physiological characteristics of human breathing; 2. The ratio of hydrogen and oxygen produced by water electrolysis must be 2:1, that is, 66.66% hydrogen and 33.33% oxygen. Such high concentrations of hydrogen and oxygen are not managed for humidity and are directly transported to the respirator for human inhalation. When the gas flows in the pipeline, it is easy to generate static electricity, resulting in flash combustion, detonation or explosion, which poses certain safety hazards; 3. In this scheme, the hydrogen and oxygen produced by electrolysis are directly supplied to the human body through a closed pipeline for inhalation. According to the relevant physiological characteristics of the human respiratory and circulatory organs, more than 90% of the inhaled hydrogen is still not metabolized and discharged from the body with exhalation. If static electricity is generated within 1.5 meters around the human body and the equipment, there is still a risk of flash combustion, detonation or explosion; if the user is indoors, especially when the indoor space is small, the discharged hydrogen is easy to accumulate in large quantities, which poses a great safety hazard. Summary of the invention

[0008] In order to solve the above problems, the purpose of the utility model is to provide a hydrogen-oxygen breathing system with an air storage bag, which can make the human body absorb hydrogen more comfortably, efficiently and safely, and thus remove more harmful hydroxyl free radicals in the body.

[0009] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solutions:

[0010] A hydrogen-oxygen breathing system with an air storage bag comprises an electrolytic hydrogen-oxygen generator (1), a breathing component, a sealed cabin (3) and a gas exchange system (4); the characteristics are:

[0011] The electrolytic hydrogen-oxygen generator (1) produces no less than 9 L of gas per minute to meet the human body's minute ventilation volume (6-9 L / min), wherein the hydrogen production is no less than 6 L / min and the oxygen production is no less than 3 L / min, so that the human body inhales pure hydrogen-oxygen gas reaching the tidal volume each time (the hydrogen concentration in the inhaled gas is 66.66% and the oxygen concentration is 33.33%).

[0012] The tidal volume refers to the volume of gas inhaled or exhaled each time during quiet breathing, generally referring to the expiratory volume.

[0013] The breathing assembly comprises a hydrogen air intake pipe (2-1a), a hydrogen air storage bag (2-1b), an oxygen air intake pipe (2-2a), an oxygen air storage bag (2-2b) and a breathing mask (2-3).

[0014] The upstream of the hydrogen storage bag (2-1b) in the breathing component is connected to the hydrogen output end of the electrolytic hydrogen-oxygen generator (1) through the hydrogen inlet pipe (2-1a) and the hydrogen humidifier (1-1), and is used to store the hydrogen continuously generated by the electrolytic hydrogen-oxygen generator, and is connected to the hydrogen inlet (2-3a) of the breathing mask (2-3) at the downstream. The upstream of the oxygen storage bag (2-2b) in the breathing component is connected to the oxygen output end of the electrolytic hydrogen-oxygen generator (1) through the oxygen inlet pipe (2-2a) and the oxygen humidifier (1-2), and is used to store the oxygen continuously generated by the electrolytic hydrogen-oxygen generator, and is connected to the oxygen inlet (2-3b) of the breathing mask (2-3) at the downstream. The breathing mask (2-3) is constructed with a hydrogen inlet (2-3a), an oxygen inlet (2-3b) and an outlet (2-3c); the hydrogen inlet (2-3a) and the oxygen inlet (2-3b) are respectively constructed with a hydrogen inlet one-way membrane flap (2-3a1) and an oxygen inlet one-way membrane flap (2-3b1) for allowing gas to flow into the breathing mask (2-3); and the outlet (2-3c) is provided with an outlet one-way membrane flap (2-3c1) for allowing gas in the breathing mask (2-3) to flow outwards. During the human body's inhalation phase, the one-way membrane flap at the air inlet opens, the one-way membrane flap at the air outlet closes, and the hydrogen and oxygen stored in the air storage bag flow into the breathing mask (2-3) through the air inlet; during the human body's exhalation phase, the one-way membrane flap at the air inlet closes, the one-way membrane flap at the air outlet opens, and the exhaled air flows out of the breathing mask (2-3) through the air outlet (2-3c). At this time, the hydrogen and oxygen continuously generated by the electrolytic hydrogen and oxygen generator (1) flow into the hydrogen storage bag (2-1b) and the oxygen storage bag (2-2b) respectively for use in the next inhalation, and the cycle continues.

[0015] The cross-sectional area ratio of the hydrogen inlet pipe (2-1a) and the oxygen inlet pipe (2-2a) is 2:1; the volume ratio of the hydrogen storage bag (2-1b) and the oxygen storage bag (2-2b) is 2:1; the cross-sectional area ratio of the hydrogen inlet port (2-3a) and the oxygen inlet port (2-3b) is 2:1, so as to match the hydrogen-oxygen production ratio of the electrolytic hydrogen-oxygen generator (1), ensure that all the inlet pipes and the air storage bag have the same pressure, and the ratio of hydrogen to oxygen inhaled by the human body each time is 2:1.

[0016] The sealed cabin (3) is arranged indoors, and a hydrogen concentration monitor (3-1), an oxygen concentration monitor (3-2), a carbon dioxide concentration monitor (3-3), a humidity monitor (3-4) and a temperature monitor (3-5) are arranged inside the sealed cabin (3).

[0017] Each time a human body breathes, part of the inhaled hydrogen and oxygen is not metabolized and is discharged into the closed cabin from the outlet (2-3c) on the breathing mask (2-3) along with carbon dioxide, etc. during exhalation.

[0018] The gas exchange system (4) is arranged outside the sealed cabin (3) and connected to the sealed cabin (3) through a pipeline. Each time a human body breathes, part of the hydrogen and oxygen inhaled are not metabolized and are discharged into the sealed cabin along with carbon dioxide and the like during exhalation. The gas exchange system (4) delivers fresh air from the room into the sealed cabin (3) through the air intake pipeline (4-1), and discharges the turbid gas containing hydrogen exhaled by the human body from the sealed cabin (3) to the outside through the air outlet pipeline (4-2). By adjusting the ventilation volume of the gas exchange system (4), the hydrogen content in the closed cabin (3) is controlled to be between 2%±0.2%, the oxygen content is controlled to be between 21%-23%, and the carbon dioxide concentration is controlled to be ≤0.1%. By adjusting the humidification volume of the humidifier (4-3) on the air intake pipeline (4-1), the relative humidity in the closed cabin (3) is controlled to be between 60%-70%. By adjusting the indoor temperature, the temperature in the closed cabin (3) is controlled to be between 20°C and 30°C, so as to maintain a safe, comfortable, and constant hydrogen bathing environment in the closed cabin (3).

[0019] The gas exchange system (4) is connected to the hydrogen and oxygen output ends of the electrolytic hydrogen and oxygen generator (1) through an emergency gas supply pipeline (4-1); a valve for controlling the on-off of the emergency gas supply pipeline (4-4) is provided at the terminal connection of the emergency gas supply pipeline (4-4). When the breathing mask (2-3) is constructed as a closed mouth and nose mask, when the electrolytic hydrogen and oxygen generator (1) stops supplying gas due to a fault or other circumstances, the gas exchange system (4) activates the emergency gas supply function and supplies gas to the breathing mask (2-3) through the emergency gas supply pipeline (4-4); when the breathing mask (2-3) is constructed as a closed nose mask, when the electrolytic hydrogen and oxygen generator (1) stops supplying gas due to a fault or other circumstances, the gas in the closed cabin (3) can be breathed through the oral cavity outside the closed nose mask without activating the emergency gas supply function.

[0020] Compared with the prior art, the innovative features of the present invention are as follows:

[0021] The air storage bag and the one-way membrane flap structure of the air inlet in the breathing component of the utility model can store the hydrogen and oxygen continuously produced by the electrolytic hydrogen-oxygen generator in the air storage bag respectively during the exhalation stage of the human body, and will not be discharged with the exhalation, thereby solving the problems of the prior art of relying on a power pump to deliver air, especially forced delivery of air during the exhalation stage of the human body, which brings discomfort to the user and wastes hydrogen, oxygen, electrolyzed water and electricity. It is more in line with the normal respiratory physiological characteristics of the human body and realizes comfortable, economical and efficient hydrogen inhalation. According to human respiratory physiology, the time ratio of inhalation to exhalation during normal human breathing is 1:1.5~2. Taking the human tidal volume of 400ml, one breath taking 3 seconds, and the inhalation to exhalation ratio of 1:2 as an example, the gas production of the electrolytic hydrogen-oxygen generator of the utility model is only 133.33ml / s, while the gas production of the electrolytic hydrogen-oxygen generator of the prior art needs to reach 400ml / s. The gas production of the electrolytic hydrogen-oxygen generator required by the technology is only 33.3% of the gas production of the electrolytic hydrogen-oxygen generator of the prior art, saving two-thirds of the water and electricity required for electrolysis.

[0022] The utility model avoids the potential safety hazards caused by the uncontrolled discharge of hydrogen and oxygen brought out by the human body with exhalation after inhaling hydrogen-oxygen mixed gas by setting up a closed closed cabin and a gas exchange system. At the same time, the hydrogen brought out by the human body when exhaling is reused as a hydrogen source, providing a safe, comfortable and constant hydrogen bathing environment in the closed cabin, and the human body can further absorb hydrogen through the skin, truly realizing the efficient use of hydrogen.

[0023] The utility model maintains the relative humidity of the gas in the system between 60% and 70% through humidifiers on the hydrogen intake pipeline, the oxygen intake pipeline and the air intake pipeline, ensures that the absolute humidity in the gas flow pipeline and the closed cabin of the system is ≥10mg / L when the temperature is between 20℃ and 30℃, avoids the generation of static electricity, effectively prevents the danger of instantaneous combustion, detonation or explosion of hydrogen and oxygen in the pipeline, the mask and the closed cabin, and realizes safe and comfortable hydrogen inhalation.

[0024] Generally speaking, under normal pressure, when the absolute humidity is ≥10g / L, static electricity is not easy to be generated, and the relative humidity is ≥60% at this time; the ambient temperature is 20-30℃, and the human body feels relatively comfortable. When the temperature is higher than 30℃ and the humidity is greater than 70%, the human body feels stuffy. In order to ensure a safe and comfortable hydrogen inhalation environment, the solid solution selects a relative humidity of 60%-70% and a cabin temperature of 20℃-30℃. The utility model ensures the safety of users in the cabin when the electrolytic hydrogen-oxygen generator stops supplying gas due to a malfunction or other circumstances by setting an emergency gas supply pipeline. When the user inhales a hydrogen-oxygen mixed gas with a closed oral and nasal mask, if the electrolytic hydrogen-oxygen generator stops supplying gas due to a malfunction or other circumstances, the gas exchange system immediately starts the emergency gas supply pipeline to supply gas to the breathing mask, avoiding the risk of suffocation of the user and further realizing safe hydrogen inhalation.
