Description

[Technical Field]

[0001] The present disclosure relates to adjustable respiratory systems, and more particularly to concentration-modulatable hydrogen-oxygen mixed gas generator respiratory systems as artificial respirators. [Background technology]

[0002] Hydrogen exists primarily in compounds such as water and organic materials on Earth. Hydrogen is a colorless, odorless, and tasteless nonmetallic gas. Due to its properties, such as non-toxicity, zero radiation, ease of recovery, and high energy release upon reaction with oxygen, hydrogen has a wide range of applications in the fields of chemistry, physics, engineering, and physiology. In particular, in medicine, as published in "Hydrogen / oxygen therapy for the treatment of an acute exacerbation of chronic obstructive pulmonary disease (COPD): results of a multicenter, randomized, double-blind, parallel-group controlled trial" (Zhang et al., 2021, 22:149, Respiratory Research) (Non-Patent Document 1), patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD) currently receive relatively high concentrations of inhaled oxygen as a standard treatment. However, compared to the control group, which received only oxygen after a plateau phase that was not continuously improveable, the experimental group that received hydrogen + oxygen treatment showed a greater improvement in BCSS scores over time (from day 1 to day 7) without a confirmed plateau phase.

[0003] Furthermore, Ji-Bing Chen, You-Yong Lu, and Ke-Cheng Xu published "A narrative review of hydrogen oncology: from real-world survey to real-world evidence" in Medical Gas Research (2020) (Non-Patent Document 2), reporting on previous real-world studies in hydrogen oncology. They found that adding a certain amount of hydrogen to inhaled gas effectively improved dyspnea in many cancer patients, over 40% of patients experienced significant improvements in their quality of life, some patients experienced reductions in tumor markers, and patients with nasopharyngeal carcinoma experienced calmer secretions. Scientists speculated that adding hydrogen to inhaled gas may enhance its antioxidant activity by reacting with hydroxyl free radicals to prevent damage to the body. Similar findings can be found in Oncology Letters (2020, 20:258) (Non-Patent Document 3).

[0004] Research into respiratory therapy has revealed that adding hydrogen to relatively high concentrations of oxygen is a very important direction for treatment in current medical research. Hydrogen can be obtained, for example, by thermochemical methods, the water-gas shift reaction, water electrolysis, and steam reforming. In particular, a natural gas steam reformer is a mass-production method for hydrogen production. When steam and methane react at high temperatures of around 1000–1400°K, hydrogen can be produced along with carbon monoxide. In this reaction, the lower the pressure applied to the reaction process, the higher the efficiency of hydrogen production. Furthermore, higher pressures are preferred for hydrogen purification systems. To shorten the production time at the expense of high pressure, the reaction system is ultimately applied with high pressure. Therefore, this system may limit the hydrogen production efficiency. Nevertheless, the production process requires both high pressure and high temperature. However, under such conditions, hydrogen molecules can easily break down into high-potential energy hydrogen atoms and react with other elements. This can significantly reduce the purity of the hydrogen produced. Furthermore, due to this high activity, storing large amounts of hydrogen always poses a major safety concern.

[0005] Another typical hydrogen production process is water electrolysis, in which an electrolyte is added to pure water to dissolve ions. By passing a direct current through a pair of electrodes, the water electrolysis reaction occurs, where water is electrolyzed into hydrogen and oxygen through an oxidation-reduction reaction. However, because the added electrolyte is usually a strong acid or base, this method poses significant safety concerns for medical applications. However, pure water cannot be electrolyzed without this electrolyte.

[0006] A new technology being developed using a proton exchange membrane (PEM) allows pure water to be electrolyzed without the involvement of an electrolyte. In a water electrolysis device, pure water enters the reaction chamber from the anode side. In addition to the electrodes, a metal mesh-shaped anode diffusion layer and an anode catalyst layer are also provided in the reaction chamber. By electrolysis, the pure water is separated into oxygen ions and hydrogen ions through the Anode diffusion layer and catalyst layer. The oxygen ions are conducted to the Anode metal mesh, releasing electrons and being discharged as oxygen. Meanwhile, the hydrogen ions pass through the PEM to the cathode catalyst layer and cathode diffusion layer. Due to the conductivity and permeability of the cathode diffusion layer, electrons supplied from the cathode are accepted by protons (hydrogen ions) and reduced to hydrogen, which is discharged.

[0007] The hydrogen and oxygen obtained from the electrolysis described above are potentially dangerous in normal environments. At concentrations ranging from 4% to 94% and temperatures above 287°C, hydrogen can ignite and explode. Because respiratory treatment is applied directly to patients, complete safety for patients and medical facilities must be ensured. Therefore, medical applications must be more careful and conservative than industrial applications, and how to increase the overall safety of use is the central focus of this disclosure.

[0008] Second, ongoing real-world research has shown that individual treated patients may have different requirements for the mixture ratio of hydrogen and oxygen. Therefore, how to conveniently adjust the concentration of hydrogen and oxygen through the respiratory system is the second point to be addressed by the present disclosure.

[0009] The detailed configuration and advantageous effects of the present disclosure are described in the following embodiments, and the contents thereof are sufficient for those skilled in the art to understand and implement the technical contents of the present disclosure. Those skilled in the art will easily understand the problems and advantageous effects of the present disclosure based on the present disclosure in the specification, the following claims and the drawings. Summary of the Invention

[0010] The main objective of this disclosure is to provide an adjustable breathing system for a concentration-modulated hydrogen-oxygen ventilator that integrates a pure water electrolysis hydrogen-oxygen generator with a humidifier bottle and a hydrogen concentration detector. The purified water in the humidifier bottle maintains the hydrogen-oxygen mixed gas at a temperature close to room temperature, effectively preventing a sudden rise in temperature that could cause a risk of combustion or explosion. Furthermore, the design of the hydrogen concentration detector effectively reduces safety hazards.

[0011] Another object of the present disclosure is to provide an adjustable breathing system of a concentration modulatable hydrogen-oxygen ventilator that can cut off the power to the pure water electrolysis hydrogen-oxygen generator by discreetly detecting hydrogen leaks in the surrounding environment with a hydrogen concentration detector embedded or installed in the room, thereby interrupting the continuous generation of hydrogen and oxygen to prevent any accidents.

[0012] A further object of the present disclosure is to provide an adjustable respiratory system for a concentration-modulatable hydrogen-oxygen ventilator, which allows the concentration of gas inhaled by the user to be changed by modulating the current to control the output efficiency of pure water electrolysis hydrogen-oxygen generation.

[0013] A further object of the present disclosure is to provide an adjustable breathing system of a concentration-modulatable hydrogen-oxygen ventilator, in which nitrogen gas in the air is filtered out by a molecular sieve, a compressor is employed to control the output efficiency of the filtered oxygen to the purified water in the humidifier, thereby adjusting the oxygen ratio in the mixed gas output, and a gas regulating valve is further employed to adjust the ratio of hydrogen and oxygen to control the gas throughput in the regulating tube.

[0014] To achieve the above object, the present disclosure relates to an adjustable breathing system for a concentration-modulatable hydrogen-oxygen artificial respirator configured to change the concentration of at least a gas inhaled by a user, the breathing system including: a supply hydrogen-oxygen mixed gas auxiliary device configured to supply a portion of the gas inhaled by the user; a pure water electrolysis hydrogen-oxygen generator for separating pure water into hydrogen and oxygen outputs, the respiratory system including at least one ion exchange membrane that allows ions to pass through, one oxidation catalyst layer and one reduction catalyst layer coated on two opposing surfaces of the ion exchange membrane, a pair of diffusion metal layers having a plurality of pores, each of which includes an anode metal layer adjacent to the oxidation catalyst layer and a cathode metal layer adjacent to the reduction catalyst layer; at least one pair of electrodes, each of which includes an anode conductively connected to the anode metal layer and a cathode conductively connected to the cathode metal layer; and a sealed housing body for housing the ion exchange membrane, the diffusion metal layer, and the electrodes. the hydrogen-oxygen generator comprises a sealed housing body having a water inlet, a hydrogen port, and an oxygen port, the body being provided with a water inlet, a hydrogen port, and an oxygen port, and deionized water can be injected into the sealed housing body through the water inlet; a humidifier bottle for holding purified water, the humidifier bottle having an oxygen delivery tube connected to the oxygen port, a hydrogen delivery tube connected to the hydrogen port, and a humidified mixed gas connected to a supply hydrogen-oxygen mixed gas auxiliary device, wherein one end of the oxygen delivery tube distal to the oxygen port, the other end of the hydrogen delivery tube distal to the hydrogen port, and the other end of the humidified mixed gas output tube positioned higher than the purified water supply to the auxiliary device; and a hydrogen concentration detector configured to detect hydrogen concentration and output an alarm signal when the hydrogen concentration exceeds a predetermined standard or limit.

[0015] In the present disclosure, by integrating a humidifier bottle and a hydrogen concentration detector, the pure water electrolysis hydrogen-oxygen generator can maintain the output hydrogen and oxygen mixed gas at a constant temperature near room temperature, effectively preventing excessively high operating temperatures that could potentially cause gas explosions or combustion risks and pose safety risks to users. The hydrogen concentration detector can also detect whether hydrogen leaks and causes abnormal changes in the environment. An alarm signal can be sent to the system, which can cut off power to the pure water electrolysis hydrogen-oxygen generator to interrupt the continuous generation of hydrogen and oxygen. Furthermore, by incorporating a molecular sieve, more oxygen can be provided. The oxygen from the molecular sieve is introduced into the purified water in the humidifier bottle, allowing the oxygen ratio to be adjusted by the molecular sieve compressor, and the hydrogen-oxygen distribution and gas throughput to be adjusted using a gas control valve.

[0017] Hereinafter, the embodiments of the present disclosure will be described with reference to specific examples, and those skilled in the art will easily understand other advantages and effects of the present disclosure from the description in this specification.

[0018] The structures, ratios, and sizes shown in the drawings are intended only to facilitate understanding and reading of the present description or specification by those skilled in the art, and are not intended to limit the present disclosure. Therefore, they have no substantial technical meaning, and any structural modifications, changes in ratio relationships, or size adjustments are within the scope of the present disclosure without affecting the effects produced by the present disclosure or the problems achieved by the present disclosure. In addition, terms such as "1," "2," or "above" used herein are intended only to facilitate explanation and do not limit the scope of the present disclosure. Furthermore, any corresponding changes or adjustments in relative relationships are considered to be within the scope of the present disclosure without any substantial changes in technical content.

[0019] 1, 2, and 3 show a pure water electrolysis hydrogen-oxygen generator 1 according to a first exemplary embodiment of the present disclosure. The pure water electrolysis hydrogen-oxygen generator 1 is housed in a sealed housing body 2, which is provided with a water inlet 20, a hydrogen hole 22, and an oxygen hole 24. Deionized water injected into the sealed housing body 2 through the water inlet 20 is sealed in the sealed housing body 2 and is connected to the oxygen hole 24 and the hydrogen hole 22.

[0020] Referring to FIG. 2 , the ion exchange membrane 10 in the pure water electrolysis hydrogen-oxygen generator 1 is set as the center line of symmetry. An oxidation catalyst layer 100 and a reduction catalyst layer 102 are coated on two opposing surfaces of the ion exchange membrane 10, respectively. The diffusion metal layer 11 is composed of an anode metal layer 110 adjacent to the oxidation catalyst layer 100 and a cathode metal layer 112 adjacent to the reduction catalyst layer 102. Each diffusion metal layer is provided with a plurality of pores 114 so that the generated hydrogen molecules or oxygen molecules can be easily separated and discharged from water after the hydrogen ions or oxygen ions are oxidized or reduced, respectively, thereby improving gas generation efficiency. The electrode 12 is composed of an anode electrode 120 conductively connected to the anode metal layer 110 and a cathode electrode 122 conductively connected to the cathode metal layer 112.

[0021] A humidifier bottle 3 is further provided, which includes a hydrogen delivery tube 30 inserted into the hydrogen hole 22, an oxygen delivery tube 32 inserted into the oxygen hole 24, and a humidified mixed gas output tube 34 connected to a hydrogen-oxygen mixed gas supply auxiliary device 13 (e.g., a nasal cannula). One end of the oxygen delivery tube 32 distal to the oxygen hole 24 and the other end of the hydrogen delivery tube 30 distal to the hydrogen hole 22 are inserted into a bottle body 36 and immersed in clean water filled in the bottle body 36. The other end of the humidified mixed gas output tube 34 distal to the hydrogen-oxygen mixed gas supply auxiliary device 13 is also inserted into the bottle body 36, but is positioned higher than the clean water.

[0022] In operation, deionized water is injected through the water inlet 20 of the sealed housing body 2 until the liquid level is near the oxygen hole 24 or the hydrogen hole 22, and then the switch is turned on to energize the electrode 12, starting the electrolysis process. Space for the circulating deionized water is secured through multiple pores in the diffusion metal layer 110 to the oxidation catalyst layer 100 and multiple pores in the diffusion metal layer 112 to the reduction catalyst layer 102, respectively. When deionized water contacts the metal layer 110, which is connected to the anode 120, positively charged hydrogen ions or negatively charged hydroxide ions are released through the ion exchange membrane 10 from the side of the catalyst layer 100 to the opposite side of the catalyst layer 102. In this example, the ion exchange membrane is a proton exchange membrane, which allows hydrogen ions to pass through the proton exchange membrane 10, thereby causing an electric current to flow and a redox reaction to occur.

[0023] Furthermore, hydrogen ions pass through the ion exchange membrane 10 and the reduction catalyst layer 102 and contact the diffusion metal layer 11, which constitutes the multiple pores 114 of the cathode metal layer 112. This causes the cathode 122 to widely release electrons, which combine with the hydrogen ions to form hydrogen molecules. If the ion exchange membrane is an anion exchange membrane instead of a proton exchange membrane, as shown in FIG. 7, hydroxide ions pass through the ion exchange membrane 10 and contact the anode metal layer 110 connected to the anode 120, releasing electrons to form oxygen molecules. Because the electrolysis process uses deionized pure water, there is no strong acid or base, and hydrogen of higher purity can be effectively obtained. The hydrogen is then discharged into clean water through the hydrogen supply pipe 30, while the oxygen is discharged into clean water through the oxygen supply pipe 32. The hydrogen and oxygen are then mixed into the desired hydrogen-oxygen mixed gas. Since the temperature of the purified water is maintained at a fixed normal temperature suitable for the human body, the hydrogen and oxygen can be limited to a safe temperature range far below the flammable temperature, thereby preventing a sudden rise in temperature from exposing the user or medical facilities to the risk of explosion or combustion. The hydrogen-oxygen mixed gas is discharged through the humidified mixed gas output pipe 34 positioned higher than the purified water in the bottle body 36, and is supplied to the user for inhalation via the hydrogen-oxygen mixed gas supply auxiliary device 13.

[0024] Because this example does not use a mask to deliver the mixed gas, the concentration of gas dispensed into the chamber and administered to the user generally contains approximately 22% oxygen and 4% hydrogen, with the remainder being nitrogen. Of course, if the patient has special needs, an open nasal cannula may not be used here. Instead, gas is delivered under more rigorous room air conditioning, increasing the volume and accuracy of the hydrogen-oxygen ratio.

[0025] To prevent hydrogen from leaking from the sealed housing body, a hydrogen concentration detector 14 (SnO2 resistor) is disposed on the side of the sealed housing body close to the hydrogen hole 22 and configured to output an alarm signal while the concentration of hydrogen exceeds a predetermined standard or limit.

[0026] Also, please refer to FIG. 4. FIG. 4 is a structural schematic diagram of a pure water electrolysis hydrogen-oxygen generator with gas throughput adjustment capability according to the present disclosure, in which the pure water electrolysis hydrogen-oxygen generator 1 is further optimized in terms of heat dissipation effect and adjustable hydrogen and oxygen ratio. To optimize the heat dissipation effect, a drain outlet 26 is provided from the sealed housing body 2, and a circulating water tank 4 is also provided. The circulating water tank 4 is connected to the water inlet 20 and the drain outlet 26, thereby achieving thermal equilibrium between the sealed housing body 2 and the circulating water tank 4. To enable the circulating water tank 4 to maintain a stable temperature state, the circulating water tank 4 can be further thermally connected to a heat sink 5 configured to conduct heat dissipation to stabilize the temperature of the water in the circulating water tank 4 and the sealed housing body 2.

[0027] Furthermore, for adjustable hydrogen and oxygen ratios, a molecular sieve 6 may be employed to increase the oxygen ratio. In some specific embodiments, the molecular sieve 6 is configured to receive oxygen by compressing air while filtering out nitrogen. The oxygen from the molecular sieve 6 is delivered through an oxygen ratio adjustment pipe 60 introduced into the purified water in the bottle body 36, thereby adjusting the oxygen ratio in the humidified mixed gas output pipe 34. The gas throughput of the oxygen ratio adjustment pipe 60 is adjusted via a gas adjustment valve 62. In specific operations, the hydrogen-oxygen mixed gas supply auxiliary device 13 is worn by a user. The original hydrogen-oxygen mixed gas passing through the purified water is humidified, and then the humidified hydrogen-oxygen mixed gas is delivered to the hydrogen-oxygen mixed gas supply auxiliary device 13 via the humidified mixed gas output pipe 34 to be supplied to the user. If the user needs to increase the oxygen content, the amount of oxygen output into the purified water can be adjusted via the gas adjustment valve 62. At this point, the oxygen content in the original hydrogen-oxygen mixed gas increases at a rate equal to the adjustment by the gas regulating valve 62. Furthermore, for the pure water electrolysis generator, the efficiency of hydrogen and oxygen production from pure water electrolysis can be increased by controlling the electrolysis current. Because the amount of oxygen produced from the molecular sieve is generally greater than that from the pure water electrolysis hydrogen-oxygen generator, controlling the electrolysis current of the pure water electrolysis hydrogen-oxygen generator primarily serves to modulate the hydrogen production rate. In this way, the modulated hydrogen-oxygen mixed gas delivered from the humidified mixed gas output pipe 34 to the hydrogen-oxygen mixed gas supply auxiliary device 13 can adjust the hydrogen and oxygen ratios. Meanwhile, the true value of the hydrogen and oxygen ratio can be instantly obtained by the gas concentration detector 130 located in the hydrogen-oxygen mixed gas supply auxiliary device 13 (i.e., the nasal cannula), and adjustments can be made as needed to adjust the predetermined hydrogen and oxygen ratio for various medical applications. This also prevents users from experiencing discomfort or adverse reactions.

[0028] Please also refer to FIG. 5. FIG. 5 is a structural schematic diagram of two sets of pure water electrolysis hydrogen-oxygen generators provided inside a sealed housing body according to a second exemplary embodiment of the present disclosure. Two sets of pure water electrolysis hydrogen-oxygen generators 1′ each centered on an ion exchange membrane are housed in a sealed housing body 2′. An oxidation catalyst layer 100′ and a reduction catalyst layer 102′ are coated on two sides of the ion exchange membrane 10′ in each individual pure water electrolysis hydrogen-oxygen generator 1′. The diffusion metal layer 11′ is composed of an anode metal layer 110′ adjacent to the oxidation catalyst layer 100′ and a cathode metal layer 112′ adjacent to the reduction catalyst layer 102′. The anode electrode 120′ is conductively connected to the anode metal layer 110′, and the cathode electrode 122′ is conductively connected to the cathode metal layer 112′. The individual pure water electrolysis hydrogen-oxygen generators 1′ are configured as a mirror image pair such that each ion exchange membrane holds a common water tank 15′. Also, the common oxygen hole 24' is located at the top of the water tank 15' of the sealed housing body 2', and the hydrogen holes 22' are located separately at the top of two sides of the sealed housing body 2'.

[0029] As mentioned above, the production efficiency of hydrogen and oxygen changes with the increase of the sealed housing body 2'. By controlling the electrolysis current, the production efficiency of hydrogen and oxygen can be controlled. Meanwhile, by providing a molecular sieve, the oxygen content can be effectively increased.

[0030] Please also refer to FIG. 6. FIG. 6 is a schematic diagram of a hydrogen concentration detector installed on the ceiling of a room. Regardless of the pattern of the above-mentioned embodiment, when applied to a room, a sensing element can be installed at the ceiling instead of the hydrogen concentration detector 14. Because hydrogen is a colorless, odorless, and highly flammable substance with a density much lower than the density of air under normal atmospheric pressure, leaked hydrogen will accumulate in the air above. If the room is poorly ventilated, the hydrogen concentration will increase, which can easily ignite and explode due to external factors. Therefore, the sensing element 140 installed on the ceiling first detects the hydrogen concentration condition, and if the hydrogen concentration exceeds a threshold, it can generate an alarm signal to the respiratory system and cut off power to both the pure water electrolysis hydrogen-oxygen generator and the molecular sieve to stop the continuous generation of hydrogen and oxygen. Of course, the hydrogen concentration detector is not limited to being installed on the ceiling; it can also be installed inside the respiratory system to detect whether hydrogen is leaking, issue an alarm, and shut down the system. Furthermore, those skilled in the art will easily understand that the hydrogen leak alarm system is not limited to hydrogen concentration detectors. A pressure detector may also be connected in the hydrogen or oxygen supply pipe, respectively, and adapted to detect pressure changes within the pipe and warn if there is a leak in the hydrogen or oxygen supply pipe, which may also provide safety.

[0031] 7 shows a third exemplary embodiment of the present disclosure. The ion exchange membrane is not limited to a proton exchange membrane that allows hydrogen ions to pass through, but may also be an anion exchange membrane that allows hydroxide ions to pass through. Thus, hydroxide ions pass through the exchange membrane and are thereby charged in this example.

[0032] The above-described exemplary embodiments merely illustrate the principles and advantages of the present disclosure, and are not intended to limit the present disclosure. Those skilled in the art may modify the exemplary embodiments without departing from the spirit and scope of the present disclosure. Accordingly, the scope of protection contemplated by the present disclosure is limited by the following claims.
