Description

Breathing system with adjustable concentration of hydrogen and oxygen generator Technical Field

[0001] The present invention relates to a respiratory system, in particular to a respiratory system with a hydrogen and oxygen generator with adjustable concentration. Background Art

[0002] Most of the hydrogen on Earth exists in the form of water and organic compounds. Hydrogen is a colorless, odorless, tasteless, non-metallic gas. It is non-toxic and non-radioactive, easy to collect, and can even react with oxygen to produce high energy, making it widely used in chemistry, physics, engineering, and even physiology. In particular, in medicine, according to "Hydrogen / oxygen therapy for the treatment of an acute exacerbation of chronic obstructive pulmonary disease: results of a multicenter, randomized, double-blind, parallel-group controlled" published in the journal Respiratory Research, 2021, 22:149 by Zhang et al. According to a recent trial, patients with acute chronic obstructive pulmonary disease (AECOPD) are currently treated with higher concentrations of oxygen. However, when the medical team compared the treatment with hydrogen and oxygen, they found that over a week of treatment, patients treated with oxygen alone showed significant improvement on the second day, but then reached a plateau and could not maintain sustained improvement. In contrast, patients treated with hydrogen and oxygen showed sustained improvement in their BCSS scores for seven consecutive days without a noticeable plateau.

[0003] Another example is the 2020 publication in the journal Medical Gas Research by Chen et al., titled "A narrative review of hydrogen oncology: from real-world survey to real-world evidence." This review, which reviewed past empirical studies on hydrogen oncology, found that adding some hydrogen to the breath of many cancer patients not only effectively improved respiratory distress but also improved overall quality of life in over 40% of patients. Some patients also experienced reduced tumor markers, and nasopharyngeal cancer patients experienced reduced secretions. Scientists theorize that by adding hydrogen to breath, the antioxidant power of hydrogen molecules is expected to react with hydroxyl radicals, thereby reducing residual hydroxyl radicals in the body and preventing harm. A similar paper was published in the journal ONCOLOGY LETTERS, 2020, 20;258.

[0004] Therefore, research in respiratory therapy has shown that adding hydrogen to higher-concentration oxygen therapy has become a key area of ​​medical research. Hydrogen can be obtained through thermochemical methods, water gasification, water electrolysis, and steam reforming. Steam reforming, when applied to natural gas, is the most scalable method for hydrogen production. When water vapor and methane react at high temperatures (approximately 1000–1400 K), they produce carbon monoxide and hydrogen. In this reaction, applying lower pressures is more efficient than applying higher pressures. However, hydrogen purification systems must operate under high pressure. To shorten the process, high pressures are often used. However, this also limits production efficiency. Furthermore, since pressure and temperature are required during the production process, even if process time can be shortened by adjusting pressure, the reduction is limited. Furthermore, hydrogen molecules readily dissociate into atomic hydrogen at high temperatures. These highly reactive atoms may react with other elements, significantly compromising hydrogen purity. Furthermore, due to the high reactivity of hydrogen, storing large quantities can pose a safety hazard.

[0005] Another common method for producing hydrogen is water electrolysis. Electrolytes are added to pure water to form an ionic solution, and direct current is passed through a pair of electrodes for electrolysis, producing hydrogen and oxygen through a redox reaction. However, this method requires the addition of electrolytes to make the pure water conductive and dissociate, especially strong acids or strong bases. Therefore, there are still considerable safety concerns in medical applications.

[0006] With the advent of proton exchange membranes, water electrolysis no longer needs to rely on the addition of electrolytes, but can directly electrolyze pure water. Pure water in the water electrolysis device enters the reaction chamber from the anode side. In addition to the electrodes, the reaction chamber is also equipped with a porous metal mesh anode diffusion layer and an anode catalyst layer. Through the action of the anode diffusion layer and the catalyst layer, pure water dissociates into oxygen ions and hydrogen ions. The oxygen ions are connected to the metal mesh of the anode and release electrons to become oxygen gas for discharge; the hydrogen ions penetrate the proton exchange membrane in the reaction chamber and further contact the cathode catalyst layer and the cathode diffusion layer. Through the conductivity and permeability of the cathode diffusion layer, they receive the electrons provided by the cathode and are reduced to hydrogen gas for discharge.

[0007] The hydrogen and oxygen produced by electrolysis are dangerous under normal circumstances. When the hydrogen concentration is between 4% and 94% and the temperature is above 287°C, the conditions necessary for combustion and explosion can be reached. Because respiratory therapy is applied directly to the patient's body, the safety of both the patient and the medical facility must be fully guaranteed. Therefore, the production and use of hydrogen for medical use requires even greater vigilance than for industrial use. Improving overall safety during use is the primary focus of this invention.

[0008] Secondly, empirical research on the use of hydrogen and oxygen produced after electrolysis in the respiratory system is ongoing. Every patient, and even non-patients, may have different requirements for the ratio of hydrogen and oxygen mixture. How to adjust the hydrogen and oxygen concentrations according to actual needs when outputting them to the recipient is the second key improvement to be sought in this invention.

[0009] Summary of the Invention

[0010] The primary purpose of this invention is to provide a breathing system with an adjustable hydrogen and oxygen concentration generator. This system combines a pure water electrolysis hydrogen and oxygen generator with a damp bottle and a hydrogen concentration detector. The clean water within the damp bottle allows the hydrogen and oxygen to be maintained at a near-room temperature, effectively preventing the risk of explosion or combustion caused by a sudden increase in the operating ambient temperature. The hydrogen concentration detector also reduces safety risks.

[0011] Another object of the present invention is to provide a breathing system with an adjustable hydrogen and oxygen concentration generator. By using a built-in hydrogen concentration detector installed in the room, it strictly detects any hydrogen leakage in the surrounding environment, thereby cutting off the power supply to the pure water electrolysis hydrogen and oxygen generator, thereby stopping the continued production of hydrogen and avoiding accidents.

[0012] Another object of the present invention is to provide a breathing system with a concentration-adjustable hydrogen and oxygen generator, which controls the output efficiency of hydrogen and oxygen produced by pure water electrolysis by adjusting the current, thereby changing the concentration of the gas breathed by the assisted person.

[0013] Yet another object of the present invention is to provide a breathing system with an adjustable hydrogen and oxygen concentration generator. This system removes nitrogen from the air through molecular sieve filtration, uses a compressor to control the molecular sieve's oxygen output efficiency, and introduces the filtered oxygen into clean water, thereby adjusting the oxygen content in the mixed output pipe. Furthermore, a gas regulating valve can be used to adjust the hydrogen and oxygen ratio and control the gas throughput of the regulating pipe.

[0014] To achieve the above-mentioned purpose, the present invention provides a breathing system with a concentration-adjustable hydrogen and oxygen generator, which is used to change the concentration of the gas breathed by at least one assisted person. The breathing system includes: a hydrogen and oxygen supply auxiliary device, which supplies part of the gas breathed by the assisted person; a pure water electrolysis hydrogen and oxygen manufacturer, which decomposes pure water into hydrogen and oxygen for output, and the pure water electrolysis hydrogen and oxygen manufacturer includes at least one ion exchange membrane for ion penetration, and an oxidation catalyst layer and a reduction catalyst layer are coated on two opposite sides of the ion exchange membrane respectively; a pair of diffusion metal layers with a plurality of pores includes an anode metal layer adjacent to the oxidation catalyst layer, and another cathode metal layer adjacent to the reduction catalyst layer; at least one pair of electrodes includes an anode for conductive connection to the anode metal layer, and a cathode for conductive connection to the cathode metal layer; and a housing for accommodating the ion exchange membrane, the diffusion metal layer, and the A sealed container body for the electrode, the sealed container body having a water inlet, a hydrogen inlet, and an oxygen inlet, wherein deionized water injected into the sealed container body through the water inlet is sealed by the sealed container body and connected to the oxygen / hydrogen inlets; a moisture bottle comprising an oxygen transmission tube connected to the oxygen inlet, a hydrogen transmission tube connected to the hydrogen inlet, a mixed moisture output tube connected to the hydrogen-oxygen supply auxiliary device, and a bottle body containing clean water, wherein the oxygen transmission tube and the hydrogen transmission tube are respectively inserted into the clean water at ends remote from the oxygen inlet and the hydrogen inlet, and the end of the mixed moisture output tube remote from the hydrogen-oxygen supply auxiliary device is higher than the clean water; and a hydrogen concentration detector for detecting the hydrogen concentration in the sealed container body and outputting a warning signal when the hydrogen concentration exceeds a predetermined standard concentration.

[0015] The pure water electrolysis hydrogen and oxygen generator provided by the present invention, through the combination of a humidity bottle and a hydrogen concentration detector, can maintain a fixed temperature of the output hydrogen, oxygen and oxygen, effectively preventing the risk of gas explosion and combustion caused by excessively high ambient temperature, thereby avoiding safety hazards to the assisted persons. At the same time, the combination of the hydrogen concentration detector can detect whether there is an abnormal change in the concentration of hydrogen leakage in the surrounding environment, and then cut off the power supply of the pure water electrolysis hydrogen and oxygen generator through the alarm processor to stop the continuous production of hydrogen, and increase the molecular sieve to provide more oxygen. The filtered oxygen molecules are then introduced into the clean water through the oxygen ratio regulating tube to adjust the oxygen ratio in the mixed humidity output tube, and the gas throughput of the hydrogen and oxygen ratio regulating tube is adjusted through the gas regulating valve.

[0026] First preferred embodiment

[0027] The first preferred embodiment of the present invention provides a pure water electrolysis hydrogen and oxygen production machine 1, as shown in Figures 1, 2 and 3. The pure water electrolysis hydrogen and oxygen production machine 1 is housed in a sealed container body 2. The sealed container body 2 has a water injection hole 20, a hydrogen hole 22, and an oxygen hole 24. The deionized water injected into the sealed container body 2 through the water injection hole 20 is sealed by the sealed container body 2 and connected to the oxygen hole 24 and the hydrogen hole 22.

[0028] For ease of explanation, referring to FIG7 , the ion exchange membrane 10 in the pure water electrolysis hydrogen and oxygen production device 1 is positioned along a symmetrical midline. An oxidation catalyst layer 100 and a reduction catalyst layer 102 are coated on opposite sides of the ion exchange membrane 10, respectively. A diffusion metal layer 11 is positioned on one side of the oxidation catalyst layer 100. An anode metal layer 110 coated on one side of the diffusion metal layer 11 corresponds to the oxidation catalyst layer 100, while a cathode metal layer 112 coated on the other side of the diffusion metal layer 11 corresponds to the reduction catalyst layer 102. Each diffusion metal layer 11 has a plurality of pores 114, allowing hydrogen and oxygen generated by oxidation or reduction of hydrogen or oxygen ions to be separated from water and discharged, thereby improving gas production efficiency. The anode 120 of the electrodes 12 is electrically connected to the anode metal layer 110, while the cathode 122 is electrically connected to the cathode metal layer 112.

[0029] On the other hand, the additional moisture bottle 3 includes a hydrogen transmission tube 30 inserted into the above-mentioned hydrogen hole 22, an oxygen transmission tube 32 inserted into the oxygen hole 24, and a mixed moisture output tube 34 connected to the hydrogen and oxygen supply auxiliary device 13 (for example, a nasal catheter). The oxygen transmission tube 32 and the hydrogen transmission tube 30 are respectively inserted into the clean water filled in the bottle body 36 at the ends away from the oxygen hole 24 and the hydrogen hole 22, and the mixed moisture output tube 34 is higher than the above-mentioned clean water at the end away from the hydrogen and oxygen supply auxiliary device 13.

[0030] During operation, deionized water is injected through the water inlet 20 of the sealed container body 2 until the liquid level approaches the oxygen port 24 and the hydrogen port 22. Then, the electrode 12 is switched on and energized to initiate dissociation. In this embodiment, space for deionized water to flow is retained between the anode metal layer 110 and the oxidation catalyst layer 100, and between the cathode metal layer 112 and the reduction catalyst layer 102. When the deionized water contacts the anode metal layer 110 connected by the anode 120 through the oxidation catalyst layer 100 and the cathode metal layer 112 connected by the cathode 122 of the reduction catalyst layer 102, positively charged hydrogen ions and negatively charged hydroxide ions are released, respectively. Since the ion exchange membrane in this embodiment is a proton exchange membrane, it allows hydrogen ions to pass through, causing current to flow.

[0031] To further illustrate, among the hydroxide ions, some come into contact with the anode 120 and the anode metal layer 110, releasing electrons and forming oxygen molecules; the hydrogen ions pass through the ion exchange membrane 10 and the reduction catalyst layer 102 to reach the diffusion metal layer 11 serving as the cathode metal layer 112. The cathode 122 releases electrons on a large scale through this diffusion metal layer 11, combining with the hydrogen ions to form hydrogen gas. Because deionized pure water is used in the electrolysis process, there is no interference from strong acids or strong bases, so higher purity hydrogen can be obtained efficiently. The hydrogen is then discharged into the above-mentioned clean water through the hydrogen transmission pipe 30, and oxygen is discharged into the above-mentioned clean water through the oxygen transmission pipe 32 and then mixed into the required hydrogen and oxygen. Since the temperature of the clean water is maintained at a fixed room temperature suitable for the human body, the hydrogen and oxygen can be limited to a safe temperature range far below that where combustion is possible, thereby eliminating any risk of sudden high temperature increase causing explosion and combustion, which in turn endangers the assisted person or medical institutions. The mixed hydrogen and oxygen are discharged from the mixed moisture output pipe 34, which is higher than the clean water and reaches the bottle body 36, and then supplied to the assisted person for breathing through the hydrogen and oxygen supply assistor 13.

[0032] Since a mask is not used in this embodiment, the gas concentration mixed with the indoor air and provided to the assisted person is generally applied in a ratio of about 22% oxygen, about 4% hydrogen, and the rest nitrogen. Of course, if the patient has special needs, an open nasal cannula can be used instead of other methods that more strictly control the indoor gas and increase the ratio of hydrogen and oxygen.

[0033] To control the hydrogen concentration in the sealed container body, a hydrogen concentration detector 14 (a tin dioxide (SnO2) resistor) is provided on one side of the hydrogen hole 22 in the sealed container body. When the hydrogen concentration is higher than a predetermined standard concentration, a warning signal is output.

[0034] At the same time, reference is also made to FIG4 , which is a schematic diagram of the structure of the pure water electrolysis hydrogen and oxygen production machine of the present invention with a gas throughput adjustment function. Continuing with the pure water electrolysis hydrogen and oxygen production machine 1 of the first preferred embodiment, the pure water electrolysis hydrogen and oxygen production machine 1 optimizes the heat dissipation effect and the adjustable hydrogen and oxygen ratio. To optimize the heat dissipation effect, a water outlet 26 is provided in the sealed container body 2, and a circulating water tank 4 is added. The circulating water tank 4 connects the water injection hole 20 and the water outlet 26, thereby ensuring that the temperature within the sealed container body 2 and the circulating water tank 4 reach thermal equilibrium. To maintain a stable temperature state in the circulating water tank 4, the circulating water tank 4 can also be thermally connected to a radiator 5. The radiator 5 conducts heat to stabilize the temperature of the circulating water tank 4 and the clean water within the sealed container body 2.

[0035] On the other hand, for the adjustable hydrogen-oxygen ratio, the oxygen allocation can be improved by adding a molecular sieve 6. The specific function of the molecular sieve 6 is to filter nitrogen in the air. The molecular sieve 6 is connected to an oxygen ratio adjustment tube 60. The oxygen ratio adjustment tube 60 is used to introduce the filtered oxygen molecules into the clean water, thereby adjusting the oxygen ratio in the mixed moisture output tube 34. The gas throughput of the oxygen ratio adjustment tube 60 is then adjusted through the gas adjustment valve 62. During specific operation, the aforementioned hydrogen-oxygen supply auxiliary device 13 is worn by the assisted person. The original hydrogen-oxygen gas passes through the clean water, so that the entire hydrogen-oxygen gas contains water vapor, and is then transported to the hydrogen-oxygen supply auxiliary device 13 through the mixed moisture output tube 34 and provided to the assisted person. When the assisted person needs to increase the oxygen content, the oxygen output amount can be adjusted to the clean water through the gas adjustment valve 62. At this time, the oxygen content in the original hydrogen-oxygen gas increases proportionally with the adjustment of the gas adjustment valve 62. In addition, the pure water electrolysis production unit can also increase the efficiency of hydrogen and oxygen production by pure water electrolysis by controlling the electrolysis current. Because the molecular sieve oxygen production is generally greater than the oxygen production of the pure water electrolysis hydrogen and oxygen machine, controlling the electrolysis current of the pure water electrolysis hydrogen and oxygen machine is mainly used to adjust the hydrogen production ratio. The mixed moisture output pipe 34 is thus transported to the hydrogen and oxygen supply auxiliary device 13 for provision to the assisted person, thereby achieving the effect of adjusting the hydrogen and oxygen ratio. Regarding the aforementioned hydrogen and oxygen ratio adjustment, if the hydrogen and oxygen ratio is not set, the gas concentration detection device 130 provided in the hydrogen and oxygen supply auxiliary device 13 (nasal catheter) can immediately determine whether the hydrogen and oxygen ratio is correct, and timely adjustments can be made to prevent the assisted person from feeling uncomfortable or even experiencing adverse reactions.

[0036] Second preferred embodiment

[0037] The second preferred embodiment provided by the present invention is shown in FIG5 , which is a cross-sectional view of the internal structure of two sets of pure water electrolysis hydrogen and oxygen manufacturers in a sealed container body. Two sets of pure water electrolysis hydrogen and oxygen manufacturers 1' centered on ion exchange membranes are installed in the sealed container body 2'. In each pure water electrolysis hydrogen and oxygen manufacturer 1', an oxidation catalyst layer 100' and a reduction catalyst layer 102' are coated on both sides of the ion exchange membrane 10', and a diffusion metal layer 11' is arranged on one side of the oxidation catalyst layer 100'. The anode metal layer 110' coated on one side of the diffusion metal layer 11' corresponds to the oxidation catalyst layer 100', and the other diffusion metal layer 11' is coated on one side. The cathode metal layer 112' of the cloth corresponds to the reduction catalyst layer 102', and the anode 120' is connected to the above-mentioned anode metal layer 110', and the cathode 122' is connected to the cathode metal layer 112'. Each pure water electrolysis hydrogen and oxygen production machine 1' is set in a mirror-reflective manner, so that the anode common water tank 15' is clamped in each anode 120', and the oxygen hole 24' located on the sealed container body 2' corresponds to the anode common water tank 15', and the hydrogen hole 22' is arranged on both sides of the sealed container body 2'.

[0038] From the above, it can be seen that the hydrogen and oxygen flow rates can be controlled by increasing the sealed container body 2' and changing the current. At the same time, the addition of molecular sieves can effectively change the oxygen content.

[0039] Referring also to FIG6 , there is shown a schematic diagram of a hydrogen concentration detector installed in a room and mounted on the ceiling. Regardless of the aforementioned embodiments, when used in a room, the hydrogen concentration detector 14 can be equipped with an additional sensing element 140 mounted on the ceiling. Since hydrogen is a colorless, odorless, and highly flammable substance, and its density is much lower than that of air at normal atmospheric pressure, when hydrogen leaks, it accumulates above the air. In poorly ventilated rooms, hydrogen concentration increases, making it highly susceptible to ignition and explosions due to external factors. Therefore, the sensing element 140 mounted on the ceiling can immediately determine the hydrogen concentration. Upon receiving a signal indicating excessive hydrogen concentration, an alarm device (not shown) connected to the sensing element 140 will issue an alarm and simultaneously cut off the power supply to the pure water electrolysis hydrogen and oxygen generator, thereby preventing the continued production of hydrogen. Of course, the hydrogen concentration detector is not limited to being placed on the ceiling. It can also be placed inside the hydrogen and oxygen generator to detect hydrogen leaks and alarm shutdown. As those skilled in the art will readily understand, the hydrogen concentration detector is not limited to the above-mentioned sensing element. A pressure detector device can also be connected to the hydrogen transmission pipe and the oxygen transmission pipe respectively. By detecting the pressure change in the pipe, it can serve as a warning of whether the hydrogen transmission pipe and the oxygen transmission pipe have leaks, thereby also providing safety.

[0040] Third preferred embodiment

[0041] The third preferred embodiment of the present invention is shown in FIG7 . Since the ion exchange membrane is not limited to a proton exchange membrane that allows hydrogen ions to pass through, a cation exchange membrane that allows hydroxide ions to pass through can also be used instead. Therefore, in this embodiment, it is the hydroxide ions that are charged by the exchange membrane.

[0042] The above embodiments are intended only to illustrate the principles and effects of the present invention and are not intended to limit the present invention. Anyone skilled in the art may modify the above embodiments without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be as set forth in the claims set forth below.
