Description

High-pressure carbon monoxide chamber and its carbon monoxide concentration control method

[0001] The present invention relates to a high-pressure carbon monoxide chamber and a method for controlling the carbon monoxide concentration thereof. More specifically, the invention relates to a high-pressure carbon monoxide chamber and a method for controlling the carbon monoxide concentration thereof, configured to control the carbon monoxide concentration inside the chamber based on the carbon monoxide hemoglobin (COHb) concentration level of the user inside the chamber while providing the user with the therapeutic effect of carbon monoxide.

[0002] This application claims the benefit of priority based on Korean Patent Application No. 10-2025-0002142 dated January 7, 2025, and all contents disclosed in the document of said Korean patent application are incorporated herein as part of this specification.

[0003]

[0004] Carbon monoxide (CO) is a colorless, odorless, and tasteless gaseous molecule that is toxic and lethal to living organisms. Since carbon monoxide binds to hemoglobin (Hb) in red blood cells more readily than oxygen, inhaled carbon monoxide generates carboxyhemoglobin (COHb). This reduces the amount of oxygen available for transport throughout the body, causing hypoxia. Carbon monoxide poisoning can result in symptoms ranging from mild ones such as slight headaches, dizziness, nausea, and vomiting, to severe ones including poor capillary circulation, fainting, seizures, cardiopulmonary failure, cardiac arrest, and death.

[0005] However, contrary to the known toxicity of carbon monoxide, research is being conducted on carbon monoxide acting as a regulatory factor in intracellular and biological processes, and this research is even extending to the application of carbon monoxide as an active ingredient in the treatment of various diseases, including metabolic disorders.

[0006] Meanwhile, hyperbaric oxygen chambers are used to treat various diseases by supplying high-purity or 100% concentration oxygen in an environment where the pressure is higher than atmospheric pressure. Typically, they are used to improve the therapeutic effect and quality by effectively supplying oxygen to tissue cells damaged by decompression sickness, trauma, inflammation, edema, and bacterial infections. Recently, in addition to traditional medical hyperbaric oxygen therapy, hyperbaric oxygen chambers are also being used for hyperbaric adaptation training, non-medical treatments under relatively low pressure, or health purposes.

[0007] Korean Published Patent Application No. 10-2022-0164172 provides a high-pressure chamber in which condensate generated from an air conditioning device for controlling the internal temperature of a high-pressure oxygen chamber can be discharged to the outside of the chamber. In addition, although there are various prior patents regarding high-pressure chambers, all of them are patents aimed at improving or solving problems related to high-pressure oxygen therapy and do not disclose anything regarding high-pressure carbon monoxide chambers.

[0008] This invention is an application supported by a national research and development project of the Republic of Korea, and detailed information is as follows.

[0029] The problem to be solved by this specification is not limited to what is described above and can be extended to various matters that can be derived from the embodiments of the invention described below.

[0030]

[0031] A high-pressure carbon monoxide chamber according to one embodiment of the present invention may include: a gas supply unit for supplying a gas containing carbon monoxide; a carbon monoxide concentration measuring unit for measuring a carbon monoxide concentration within the chamber; a carbon monoxide hemoglobin concentration measuring unit for measuring a carbon monoxide hemoglobin (COHb) concentration of a user within the chamber; and a control unit for generating a carbon monoxide concentration control signal within the chamber based on the value of the user's hemoglobin concentration measured by the carbon monoxide hemoglobin concentration measuring unit.

[0032] A method for controlling the concentration of carbon monoxide in a high-pressure carbon monoxide chamber according to another embodiment of the present invention may include the steps of: creating a high-pressure state in which the pressure in the chamber is higher than atmospheric pressure; supplying a gas containing carbon monoxide; measuring the concentration of carbon monoxide in the chamber; measuring the concentration of carbon monoxide hemoglobin of a user inside the chamber; and controlling the concentration of carbon monoxide inside the chamber.

[0033]

[0034] According to one embodiment of the present invention, since the carbon monoxide hemoglobin (COHb) concentration level of a user inside the chamber can be measured while supplying a gas containing carbon monoxide inside the chamber in a high-pressure environment, there is an advantage of being able to secure reference information for controlling the carbon monoxide concentration inside the chamber.

[0035] In addition, according to one embodiment of the present invention, since the control unit generates a control signal to increase or decrease the carbon monoxide concentration inside the chamber based on the carbon monoxide hemoglobin concentration level of the user inside the chamber, the carbon monoxide concentration control has the advantage of being performed in consideration of the user's condition.

[0036] In addition, according to one embodiment of the present invention, the supply valve and the exhaust valve can be opened or closed according to a control signal of the control unit, thereby having the advantage of being able to control the carbon monoxide concentration inside the chamber by controlling the inflow of gas supplied into the chamber or the discharge of gas inside the chamber.

[0037] In addition, according to one embodiment of the present invention, since at least one of carbon monoxide concentration in exhaled air, serum acid-base ratio, serum bicarbonate, serum lactate, and electrocardiogram can be measured through a user indicator measuring unit, there is an advantage in that user indicators other than carbon monoxide hemoglobin concentration values ​​can be utilized as additional judgment information.

[0038] In addition, according to one embodiment of the present invention, since a control signal can be generated based on the measurement values ​​obtained through the carbon monoxide concentration measuring unit, the carbon monoxide hemoglobin concentration measuring unit, and the user indicator measuring unit inside the chamber, the carbon monoxide concentration inside the chamber can be controlled based on the measurement results, thus having the advantage of being able to control the carbon monoxide concentration inside the chamber based on the measurement results.

[0039] In addition, according to one embodiment of the present invention, since the carbon monoxide concentration can be controlled while the inside of the chamber is formed into a high-pressure state higher than atmospheric pressure, it has the advantage of enabling operation of supplying a gas containing carbon monoxide under high-pressure conditions.

[0040] In addition, according to one embodiment of the present invention, since carbon monoxide concentration control can be performed through a configuration including gas supply inside the chamber, concentration measurement, and control signal generation, the present invention has the advantage of providing one embodiment for operating a high-pressure carbon monoxide chamber.

[0041] It should be understood that the effects of this specification are not limited to the matters described above and can be extended to various contents that can be derived from the detailed description of the embodiments of the invention below.

[0052] In the embodiments of this specification, distinct components are intended to clearly explain their respective features and do not imply that the components are necessarily separated. That is, multiple components may be integrated to form a single hardware or software unit, or a single component may be distributed to form multiple hardware or software units. Therefore, such integrated or distributed embodiments are included within the scope of the embodiments of this specification, even if not otherwise mentioned.

[0053]

[0054] FIG. 1 is a drawing illustrating the overall configuration of a high-pressure carbon monoxide chamber (100) according to one embodiment of the present invention.

[0055] Referring to FIG. 1, a high-pressure carbon monoxide chamber (100) according to one embodiment of the present invention may include a gas supply unit (110), a carbon monoxide concentration measuring unit (120), a carbon monoxide hemoglobin concentration measuring unit (130), a user indicator measuring unit (140), an air supply valve (150), an exhaust valve (160), and a control unit (170).

[0056] The gas supply unit (110) can supply gas containing carbon monoxide into the high-pressure carbon monoxide chamber.

[0057] More specifically, the gas supply unit (110) can store or receive gas containing carbon monoxide from the outside and provide a gas flow path so that it can flow into the chamber.

[0058] At this time, the term "gas containing carbon monoxide" in the present invention is not limited to a single-component pure carbon monoxide gas, but can be understood as a concept including a mixed gas in which one or more of oxygen, nitrogen, ordinary air, or carbon dioxide are mixed together with carbon monoxide. That is, the gas supply unit (110) may be configured to supply a single-component gas, or may be configured to supply a mixed gas in which multiple components are mixed.

[0059] As an embodiment, the gas supply unit (110) may include one or more gas storage tanks for storing a gas containing carbon monoxide. Such gas storage tanks may be storage tanks for storing a gas containing carbon monoxide, or storage tanks for storing a gas that does not contain carbon monoxide, such as oxygen, nitrogen, ordinary air, or carbon dioxide. In this case, each gas storage tank may be configured separately to store different gas components.

[0060] In another embodiment, the gas supply unit (110) may be configured to receive gas from an external gas source. For example, it may be configured to be connected to a central gas supply line provided in a medical institution or research facility to receive gas containing carbon monoxide or gas not containing carbon monoxide. In this case, the gas supply unit (110) may include a gas flow path connecting the external gas source and the chamber.

[0061] The gas supply unit (110) may include a flow control means for controlling the flow rate of gas supplied into the chamber. Here, "flow control means" refers to a component capable of controlling the amount of gas supplied, and may include, for example, a flow control valve, a flow regulator, or a component equivalent thereto. Such a flow control means may be included as part of the gas supply unit (110).

[0062] Additionally, the gas supply unit (110) may include a pressure regulating means for regulating the pressure of the supplied gas to suit the operating conditions inside the chamber. In the present invention, "pressure regulating means" refers to a component that regulates the pressure of the gas supplied from the gas supply unit (110) to suit the high-pressure environment inside the chamber, and may include, for example, an air or gas compressor, a high-pressure cylinder, a pressure regulating valve, a pressure reducing valve, or a pressure regulator.

[0063] According to one embodiment of the present invention, the gas supply unit (110) may be configured to supply gas into the chamber through a single supply channel. In this case, the gas containing carbon monoxide may be supplied into the chamber through the supply channel in a pre-mixed state.

[0064] According to another embodiment, the gas supply unit (110) may include two or more branched air supply pipes. In this case, gases of different components may be supplied through each air supply pipe, for example, a gas containing carbon monoxide may be supplied through one air supply pipe, and a gas not containing carbon monoxide may be supplied through another air supply pipe.

[0065] In this manner, when multiple air supply pipes are provided, the gas supply unit (110) may include a mixing space that allows the gas supplied through the air supply pipes to be mixed. In the present invention, "mixing space" refers to a space provided to allow multiple components of gas to be mixed with each other before being introduced into the chamber. This may be formed as a separate space within the air supply path, or a portion of the air supply path may be configured to perform the role of a mixing space.

[0066] Additionally, the gas supply unit (110) may further include a supply gas measuring unit positioned along the supply path to check the state of the mixed gas. The supply gas measuring unit can measure one or more of the temperature, gas components, or gas concentration of the gas before it is supplied into the chamber.

[0067] According to one embodiment of the present invention, the gas supply unit (110) may operate according to a control signal from the control unit (170). For example, according to the control signal of the control unit (170), the gas supply unit (110) may be controlled to maintain the gas supply, change the supply amount, or stop the gas supply. At this time, the operation of opening or closing the actual gas may be performed through the supply valve (150).

[0068]

[0069] The carbon monoxide concentration measuring unit (120) can measure the carbon monoxide concentration in the chamber.

[0070] More specifically, the carbon monoxide concentration measuring unit (120) can be configured to detect the concentration of carbon monoxide in the gas present inside the high-pressure carbon monoxide chamber and to check the carbon monoxide concentration state inside the chamber.

[0071] In the present invention, "carbon monoxide concentration in the chamber" may refer to the concentration of carbon monoxide in the gas present in the entire or part of the space inside the chamber. That is, the carbon monoxide concentration measuring unit (120) may be configured to measure the average carbon monoxide concentration inside the chamber, or may be configured to measure the carbon monoxide concentration at a specific location inside the chamber.

[0072] Carbon monoxide has a much higher affinity for hemoglobin than oxygen, so carbon monoxide-hemoglobin can be formed even when the amount of inhaled carbon monoxide is small. Therefore, continuously monitoring the concentration of carbon monoxide inside the chamber can be considered important in the process of providing the therapeutic, medical, and health benefits of carbon monoxide.

[0073] In one embodiment, the carbon monoxide concentration measuring unit (120) may be configured to be placed in the internal space of the chamber and to measure the carbon monoxide concentration while in contact with the gas inside the chamber. For example, it may be placed on the inner wall of the chamber, the ceiling, or near the area where the user breathes.

[0074] In another embodiment, the carbon monoxide concentration measuring unit (120) may be positioned on a gas path communicating with the inside of the chamber. For example, it may be positioned in a location communicating with the supply path or the exhaust path and configured to measure the concentration of carbon monoxide in the gas flowing into the chamber or being discharged outside the chamber.

[0075] A single carbon monoxide concentration measuring unit (120) may be provided, or multiple units may be provided at different locations inside the chamber. When multiple carbon monoxide concentration measuring units (120) are provided, differences in carbon monoxide concentration depending on the location inside the chamber can be checked.

[0076] According to one embodiment of the present invention, the carbon monoxide concentration value measured by the carbon monoxide concentration measuring unit (120) can be transmitted to the control unit (170). Depending on the carbon monoxide concentration value, the control unit (170) can generate a control signal to reduce the carbon monoxide concentration inside the chamber, a control signal to increase the carbon monoxide concentration inside the chamber, or a control signal to maintain the carbon monoxide concentration inside the chamber.

[0077] For example, if the carbon monoxide concentration inside the chamber is measured to be high, the control unit (170) can control the supply of gas containing carbon monoxide through the supply valve (150) to reduce or block the supply. Additionally, it can control the exhaust valve (160) to open so that the gas inside the chamber is discharged to the outside.

[0078] As another example, if the carbon monoxide concentration inside the chamber is measured to be low, the control unit (170) can control the supply of gas containing carbon monoxide through the supply valve (150) to maintain or increase the supply.

[0079] In this way, the carbon monoxide concentration measuring unit (120) can be configured to measure the carbon monoxide concentration inside the chamber, and as the measured result is transmitted to the control unit (170), the opening or closing operation of the supply valve (150) and the exhaust valve (160) can be performed.

[0080]

[0081] The carbon monoxide hemoglobin concentration measuring unit (130) can measure the carbon monoxide hemoglobin (COHb) concentration of the user inside the chamber.

[0082] More specifically, the carbon monoxide hemoglobin concentration measuring unit (130) may be configured to measure the ratio or concentration of hemoglobin bound to carbon monoxide in the user's blood using a biosignal obtained from a user located inside the chamber.

[0083] In the present invention, the term "carbon monoxide hemoglobin (COHb) concentration" can be understood as the relative ratio of hemoglobin bound to carbon monoxide relative to total hemoglobin in the user's blood, or a corresponding value. This COHb concentration can be used as an indicator reflecting the degree of accumulation of carbon monoxide inhaled by the user in the body.

[0084] Carbon monoxide has a much higher affinity for hemoglobin than oxygen, so COHb can be formed even when a small amount of carbon monoxide is inhaled. Therefore, in an environment where carbon monoxide is supplied to a user inside a chamber, it may be considered important to check the user's condition by directly measuring the COHb concentration.

[0085] In one embodiment, the carbon monoxide hemoglobin concentration measuring unit (130) may be configured to be placed in contact with or close to a specific part of the user's body to measure the COHb concentration. For example, it may be mounted on a finger, earlobe, or other peripheral part to perform the measurement. In this case, the measuring unit may be configured in a form that the user can wear inside a chamber, and may be, for example, a CO-oxymeter, but is not limited thereto.

[0086] In another embodiment, the carbon monoxide hemoglobin concentration measuring unit (130) may be configured to measure the COHb concentration by receiving a signal emitted or reflected from the user in a non-contact manner. In this case, the measuring unit is fixedly positioned at a certain location inside the chamber so that the measurement can be performed without direct contact with the user's body.

[0087] In one embodiment, the carbon monoxide hemoglobin concentration measuring unit (130) may be composed of a single measuring unit, or it may be configured to include a plurality of measuring units for performing measurements at different locations. When a plurality of measuring units are provided, the COHb concentration measured at different parts of the user's body can be compared and verified.

[0088] According to one embodiment of the present invention, the COHb concentration value measured by the carbon monoxide hemoglobin concentration measuring unit (130) can be transmitted to the control unit (170). Depending on whether the COHb concentration value corresponds to a preset value or a preset range, the control unit (170) can generate a control signal to reduce the carbon monoxide concentration inside the chamber or a control signal to increase the carbon monoxide concentration inside the chamber.

[0089] For example, if the measured COHb concentration value is greater than or equal to a preset value, the control unit (170) can generate a control signal to lower the carbon monoxide concentration inside the chamber. At this time, the supply of gas containing carbon monoxide can be reduced or blocked through the supply valve (150), and the gas inside the chamber can be discharged to the outside through the exhaust valve (160).

[0090] As another example, if the measured COHb concentration value is below a preset value, the control unit (170) can generate a control signal to increase the carbon monoxide concentration inside the chamber. In this case, the supply of gas containing carbon monoxide through the supply valve (150) can be maintained or increased.

[0091] Additionally, the carbon monoxide hemoglobin concentration measuring unit (130) may be configured to repeatedly measure the COHb concentration value at regular time intervals. Through this, the pattern of change in the user's COHb concentration can be confirmed while carbon monoxide is supplied inside the chamber.

[0092]

[0093] The user indicator measuring unit (140) can measure user indicators including at least one of carbon monoxide concentration in exhaled breath, serum acid-base ratio, serum bicarbonate, serum lactate, and electrocardiogram from a user inside the chamber.

[0094] More specifically, the user indicator measuring unit (140) may be configured to obtain one or more physiological indicators from a user located inside the chamber to check the user's condition.

[0095] In the present invention, the term "user indicator" refers to a physiological value that can be measured directly or indirectly from a user inside a chamber, and can be understood as a concept including one or more of carbon monoxide concentration in exhaled air, serum acid-base ratio, serum bicarbonate, serum lactate, and electrocardiogram. Such user indicators can be measured as numerical values ​​indicating changes in the user's physiological state.

[0096] In one embodiment, the user indicator measuring unit (140) may be configured to measure the concentration of carbon monoxide in exhaled breath. In this case, the user indicator measuring unit (140) may be configured to collect or detect gas emitted during the user's breathing process to measure the concentration of carbon monoxide contained in the exhaled breath. For example, it may be configured to be placed near the user's mouth or nose to detect exhaled gas.

[0097] In another embodiment, the user indicator measuring unit (140) may be configured to measure at least one of serum acid-base ratio, serum bicarbonate, or serum lactic acid. In this case, the user indicator measuring unit (140) may be configured to measure the indicator from the user, and the measurement may be performed in conjunction with a measuring device inside or outside the chamber.

[0098] In another embodiment, the user indicator measuring unit (140) may be configured to measure an electrocardiogram. In this case, the user indicator measuring unit (140) may be configured to measure an electrical signal according to the user's heart activity by including an electrode or a corresponding component attached to the surface of the user's body.

[0099] The user indicator measuring unit (140) may be configured to measure only one of the above user indicators, or may be configured to measure two or more simultaneously or sequentially. For example, it may be configured to measure carbon monoxide concentration in exhaled breath and electrocardiogram simultaneously, and may be configured to selectively measure serum acid-base ratio and serum lactate.

[0100] The user indicator measuring unit (140) may be configured to be mounted to the user inside the chamber, or it may be configured to be fixedly positioned at a certain location inside the chamber so that measurements are performed without contact with the user's body. Additionally, some user indicators may be configured so that results measured outside the chamber are received through the user indicator measuring unit (140).

[0101] According to one embodiment of the present invention, a user indicator measured through a user indicator measuring unit (140) can be transmitted to a control unit (170). Depending on the measurement result of the user indicator, the control unit (170) can generate a control signal to reduce the carbon monoxide concentration inside the chamber or a control signal to increase the carbon monoxide concentration inside the chamber.

[0102] For example, if the user indicator measured through the user indicator measuring unit (140) indicates a specific state, the control unit (170) can control the supply of gas containing carbon monoxide through the supply valve (150) to reduce or block the supply. Additionally, it can control the exhaust valve (160) to open to discharge the gas inside the chamber to the outside.

[0103] As another example, if the user indicator measured by the user indicator measuring unit (140) indicates a state in which the therapeutic, medical, or health effects of carbon monoxide are not sufficiently provided to the user inside the chamber, the control unit (170) may generate a control signal to increase the concentration of carbon monoxide inside the chamber. At this time, the control unit (170) may control the supply valve (150) according to the control signal to operate it to maintain or increase the supply of gas containing carbon monoxide.

[0104] Additionally, the user indicator measuring unit (140) may be configured to repeatedly measure the user indicator at regular time intervals. For example, while carbon monoxide is supplied inside the chamber, the user indicator measuring unit (140) may repeatedly measure the same user indicator from the user at preset time intervals. Accordingly, the change in the user indicator over time measured by the user indicator measuring unit (140) may be transmitted to the control unit (170).

[0105] When user indicators measured repeatedly in this manner are transmitted to the control unit (170), the control unit (170) can compare user indicators measured at different time points and generate one of a control signal to maintain the carbon monoxide concentration inside the chamber, a control signal to reduce the carbon monoxide concentration inside the chamber, or a control signal to increase the carbon monoxide concentration inside the chamber. In this process, the opening or closing operation of the supply valve (150) and the exhaust valve (160) can be performed according to the control signal of the control unit (170).

[0106]

[0107] The supply valve (150) can open or close the supply path through which gas is supplied from the gas supply unit (100) into the chamber according to a control signal from the control unit (170) described later.

[0108] More specifically, the supply valve (150) is positioned on the supply path connecting the gas supply unit (110) and the inside of the chamber, and can operate to allow or block the flow of gas entering the inside of the chamber through the supply path.

[0109] In the present invention, "supply path" may refer to a passage through which gas supplied from a gas supply unit (110) moves into the chamber, and a supply valve (150) may be installed at a specific location on the supply path and may be switched to an open state or a closed state. Accordingly, when the supply valve (150) is in an open state, gas supplied from the gas supply unit (110) may flow into the chamber, and when the supply valve (150) is in a closed state, the flow of gas into the chamber may be stopped.

[0110] In one embodiment, the supply valve (150) may be installed in a supply path through which a gas containing carbon monoxide is supplied. In this case, the gas supply unit (110) may discharge a mixed gas containing carbon monoxide through the supply path, and the supply valve (150) may be switched to an open or closed state in the section where the mixed gas flows into the chamber.

[0111] For example, if the control unit (170) confirms that the carbon monoxide hemoglobin concentration level of the user inside the chamber is greater than or equal to a preset value, the control unit (170) may generate a control signal to lower the carbon monoxide concentration inside the chamber, and the supply valve (150) may be switched to a blocked state according to the control signal so that the inflow of gas containing carbon monoxide into the chamber may be stopped.

[0112] In another embodiment, the supply valve (150) may be installed in a supply path through which a gas not containing carbon monoxide is supplied. For example, the gas supply unit (110) may supply a gas containing one or more of oxygen, normal air, nitrogen, or carbon dioxide through a separate supply path, and the supply valve (150) may be switched to an open or closed state in the section where the gas flows into the chamber.

[0113] In this case, when the control unit (170) generates a control signal to lower the concentration of carbon monoxide inside the chamber, the supply valve (150) is switched to an open state so that gas not containing carbon monoxide can be introduced into the chamber.

[0114] In another embodiment, the supply valve (150) may be placed in each of two or more branched supply pipes. For example, the first supply pipe may be configured to supply a gas containing carbon monoxide, and the second supply pipe may be configured to supply a gas not containing carbon monoxide, and each supply pipe may have a respective supply valve (150) installed.

[0115] In this case, the control unit (170) can operate by switching the supply valve (150) installed in the first supply pipe to a closed state and, at the same time, switching the supply valve (150) installed in the second supply pipe to an open state, thereby changing the composition of the gas flowing into the chamber.

[0116] Additionally, the supply valve (150) may operate to maintain an open or closed state when a control signal is generated to maintain the carbon monoxide concentration inside the chamber. For example, when the control unit (170) generates a control signal to maintain the carbon monoxide concentration inside the chamber, the supply valve (150) may maintain its previous operating state so that the state of the gas flowing into the chamber does not change abruptly.

[0117] For example, the supply valve may include a pressure regulating means for adjusting the gas pressure to suit the operating conditions inside the chamber. This refers to a component that regulates pressure so that the inside of the chamber becomes a high-pressure environment, and may be, for example, an air or gas compressor, a high-pressure cylinder, a pressure regulating valve, a pressure reducing valve, or a pressure regulator, but is not limited thereto.

[0118]

[0119] The exhaust valve (160) can open or close the exhaust passage through which gas is discharged from the chamber according to a control signal from the control unit (170) described later.

[0120] More specifically, the exhaust valve (160) is positioned on an exhaust passage that connects the inside of the chamber and the outside of the chamber, and can operate to allow or block the flow of gas present inside the chamber to be discharged to the outside.

[0121] In the present invention, "exhaust passage" may refer to a passage through which gas present inside a chamber moves to the outside, and an exhaust valve (160) may be installed at a specific location on the exhaust passage and may be switched to an open state or a closed state. Accordingly, when the exhaust valve (160) is in an open state, gas inside the chamber may be discharged to the outside through the exhaust passage, and when the exhaust valve (160) is in a closed state, gas inside the chamber may be retained inside the chamber.

[0122] In one embodiment, the exhaust valve (160) may be switched to an open state when the control unit (170) generates a control signal to lower the carbon monoxide concentration inside the chamber. For example, when the control unit (170) generates a control signal to lower the carbon monoxide concentration inside the chamber based on the results measured by the carbon monoxide concentration measuring unit (120) or the carbon monoxide hemoglobin concentration measuring unit (130), the exhaust valve (160) is switched to an open state so that the gas present inside the chamber can be discharged to the outside through the exhaust passage. In this process, as the gas containing carbon monoxide inside the chamber is discharged to the outside, the carbon monoxide concentration inside the chamber may be reduced.

[0123] In another embodiment, the exhaust valve (160) may operate to maintain a closed state when a control signal is generated to maintain the carbon monoxide concentration inside the chamber. For example, when the control unit (170) confirms that the carbon monoxide concentration inside the chamber is within a preset range, the exhaust valve (160) may maintain a closed state to prevent the gas inside the chamber from being discharged to the outside.

[0124] In another embodiment, the exhaust valve (160) may remain in a closed state even when a control signal is generated to increase the concentration of carbon monoxide inside the chamber. In this case, the gas containing carbon monoxide supplied inside the chamber may remain inside the chamber without being discharged to the outside.

[0125] The exhaust valve (160) can operate in conjunction with the supply valve (150). For example, when the control unit (170) generates a control signal to lower the concentration of carbon monoxide inside the chamber, the supply valve (150) operates to block the inflow of gas containing carbon monoxide, and the exhaust valve (160) can be switched to an open state to allow the gas inside the chamber to be discharged to the outside. Accordingly, the gas composition inside the chamber can be changed.

[0126] In another embodiment, a plurality of exhaust valves (160) may be provided. For example, a plurality of exhaust passages may be formed at different locations inside the chamber, and a respective exhaust valve (160) may be installed in each exhaust passage. In this case, the control unit (170) may control only some of the plurality of exhaust valves (160) to be switched to an open state, or all of them to be switched to an open state.

[0127] Additionally, the exhaust valve (160) may be configured to repeatedly perform opening and closing operations according to a control signal from the control unit (170). For example, in order to maintain the carbon monoxide concentration inside the chamber within a certain range, the exhaust valve (160) may repeat the operation of maintaining an open state for a certain period of time and then switching back to a closed state.

[0128] For example, the exhaust valve may include a pressure regulating means for regulating the gas pressure to suit the operating conditions inside the chamber. This refers to a component that regulates pressure so that the inside of the chamber becomes a high-pressure environment, and may be, for example, an air or gas compressor, a high-pressure cylinder, a pressure regulating valve, a pressure reducing valve, a pressure regulator, or a back pressure regulator, but is not limited thereto.

[0129]

[0130] The control unit (170) can generate a carbon monoxide concentration control signal inside the chamber based on the user's hemoglobin concentration value measured by the carbon monoxide hemoglobin concentration measuring unit (130).

[0131] More specifically, the control unit (170) may be configured to receive a user's carbon monoxide hemoglobin (COHb) concentration value transmitted through the carbon monoxide hemoglobin concentration measuring unit (130) and to generate a control signal to adjust the carbon monoxide concentration inside the chamber according to the received COHb concentration value.

[0132] In one embodiment, the control unit (170) may be configured to generate a control signal to lower the carbon monoxide concentration inside the chamber when the user's carbon monoxide hemoglobin concentration level is greater than or equal to a preset value. In this case, the control unit (170) may operate to reduce or stop the inflow of gas containing carbon monoxide into the chamber through a control signal transmitted to the supply valve (150), and simultaneously operate to discharge the gas inside the chamber to the outside through a control signal transmitted to the exhaust valve (160). Accordingly, the amount of gas containing carbon monoxide present inside the chamber may be reduced.

[0133] In another embodiment, the control unit (170) may be configured to generate a control signal to increase the carbon monoxide concentration inside the chamber when the user's carbon monoxide hemoglobin concentration level is below a preset value. In this case, the control unit (170) may operate to maintain or increase the inflow of gas containing carbon monoxide into the chamber through a control signal transmitted to the supply valve (150), and may operate to block the discharge of gas inside the chamber through a control signal transmitted to the exhaust valve (160). Accordingly, the carbon monoxide concentration inside the chamber may be increased.

[0134] Additionally, the control unit (170) may be configured to generate a control signal to maintain the carbon monoxide concentration inside the chamber when the carbon monoxide hemoglobin concentration level is located within a range that is neither above nor below a preset value. In this case, the control unit (170) may generate a control signal to maintain the operating state of the supply valve (150) and the exhaust valve (160).

[0135] Additionally, the control unit (170) may be configured to receive COHb concentration values ​​that are repeatedly transmitted at regular time intervals from the carbon monoxide hemoglobin concentration measuring unit (130). In this case, the control unit (170) may check for changes in COHb concentration values ​​measured at different time points and selectively generate one of a control signal to lower, a control signal to raise, or a control signal to maintain the carbon monoxide concentration inside the chamber.

[0136] In another embodiment, the control unit (170) may be configured to receive a COHb concentration value along with a carbon monoxide concentration value inside the chamber measured by a carbon monoxide concentration measuring unit (120) or a user indicator measured through a user indicator measuring unit (140). In this case, the control unit (170) may generate a control signal by taking into account the change in the carbon monoxide hemoglobin concentration value together with the change in the carbon monoxide concentration inside the chamber or the change in the user indicator.

[0137] For example, when the carbon monoxide concentration inside the chamber increases while the COHb concentration value is close to a preset value, the control unit (170) can generate a control signal to lower the carbon monoxide concentration. Conversely, when the COHb concentration value is below a preset value and the carbon monoxide concentration inside the chamber remains low, the control unit (170) can generate a control signal to raise the carbon monoxide concentration.

[0138]

[0139] FIG. 2 is a diagram illustrating the detailed configuration of a control unit according to an embodiment of the present invention.

[0140] Referring to FIG. 2, the control unit (170) may include a storage unit (171), a communication unit (172), and a processor (173).

[0141] The storage unit (171) may be configured as a device for storing carbon monoxide concentration values ​​inside the chamber, carbon monoxide hemoglobin (COHb) concentration values ​​of the user, user indicator data measured through the user indicator measuring unit (140), control signal generation history, and chamber operation status information. Additionally, the storage unit (171) may be configured to store threshold values, allowable range values, control condition information, and operation setting information used during the operation of the control unit (170).

[0142] In one embodiment, the storage unit (171) may record carbon monoxide hemoglobin concentration values ​​and carbon monoxide concentration values ​​inside the chamber measured in chronological order, thereby allowing changes in the user's condition and changes in the internal environment of the chamber to be managed together during chamber operation. Additionally, the storage unit (171) may record the history of opening or closing operations of the supply valve (150) and the exhaust valve (160).

[0143] The communication unit (172) can perform the role of transmitting and receiving measurement data, control signals, and status information between the gas supply unit (110), the carbon monoxide concentration measuring unit (120), the carbon monoxide hemoglobin concentration measuring unit (130), the user indicator measuring unit (140), the supply valve (150), and the exhaust valve (160).

[0144] In one embodiment, the communication unit (172) may be configured to transmit the carbon monoxide concentration value inside the chamber measured by the carbon monoxide concentration measuring unit (120) and the user's COHb concentration value measured by the carbon monoxide hemoglobin concentration measuring unit (130) to the processor (173). Additionally, the communication unit (172) may be configured to transmit exhaled carbon monoxide concentration, serum acid-base ratio, serum bicarbonate, serum lactate, or electrocardiogram information measured by the user indicator measuring unit (140) to the processor (173).

[0145] Additionally, the communication unit (172) may be configured to transmit a control signal generated by the processor (173) to the supply valve (150) and the exhaust valve (160) so that the opening or closing operation of each valve is performed. The communication unit (172) may be configured to perform data transmission between components via a wired communication method or a wireless communication method, and may also be configured to transmit and receive data with a monitoring device or management device outside the chamber.

[0146] The processor (173) is a component that performs the overall operation of the control unit (170) and can be configured to process measurement data received through the communication unit (172) and generate a control signal to control the carbon monoxide concentration inside the chamber.

[0147] In one embodiment, the processor (173) may be configured to analyze the user's COHb concentration value transmitted from the carbon monoxide hemoglobin concentration measuring unit (130) and determine whether the value is greater than or equal to a preset value or less than or equal to a preset value.

[0148] Additionally, the processor (173) may be configured to generate a control signal to lower the carbon monoxide concentration inside the chamber when the user's COHb concentration level is determined to be greater than or equal to a preset value. At this time, the generated control signal is transmitted to the supply valve (150) and the exhaust valve (160) through the communication unit (172), so that the inflow of gas containing carbon monoxide is reduced or blocked, and the gas inside the chamber is discharged to the outside.

[0149] Additionally, the processor (173) may be configured to generate a control signal to increase the carbon monoxide concentration inside the chamber when it is determined that the user's COHb concentration level is below a preset value. In this case, control may be performed so that the inflow of gas containing carbon monoxide through the supply valve (150) is maintained or increased, and the discharge of gas through the exhaust valve (160) is restricted.

[0150] Additionally, the processor (173) may be configured to sequentially process measurement data received at regular time intervals during the process of performing such control operations, and may be configured to record control signals and judgment results generated at each point in time in the storage unit (171). Additionally, the processor (173) may be configured to repeatedly update control signals according to state changes occurring during chamber operation.

[0151]

[0152] FIG. 3 is a flowchart illustrating a carbon monoxide measurement and concentration control process according to one embodiment of the present invention.

[0153] Referring to FIG. 3, first, in step S301, a gas containing carbon monoxide can be supplied from the gas supply unit (110) into the chamber (A). In this step, the gas supply unit (110) can perform the operation of introducing a mixed gas containing carbon monoxide (CO) into the internal space of the chamber (A) to create an internal environment of the chamber (A).

[0154] Next, in step S302, the carbon monoxide concentration measuring unit (120) can measure the carbon monoxide concentration inside the chamber (A). In this step, the carbon monoxide concentration measuring unit (120) can detect the concentration of carbon monoxide among the gas components inside the chamber (A) and generate measurement data including the carbon monoxide concentration value.

[0155] Next, in step S303, the carbon monoxide concentration measuring unit (120) can transmit the measured carbon monoxide concentration value to the control unit (170). In this step, information regarding the carbon monoxide concentration inside the chamber (A) is transmitted to the control unit (170) and can subsequently be used for control judgment.

[0156] Next, in step S304, the carbon monoxide hemoglobin concentration measuring unit (130) can measure the carbon monoxide hemoglobin (COHb) concentration from the user inside the chamber (A). In this step, the COHb concentration can be measured as an indicator representing the ratio of carbon monoxide bound to the user's body hemoglobin.

[0157] Next, in step S305, the carbon monoxide hemoglobin concentration measuring unit (130) can transmit the measured COHb concentration value to the control unit (170). In this step, the user's COHb concentration value is transmitted to the control unit (170) and can be reflected in the determination of carbon monoxide concentration control inside the chamber (A).

[0158] Finally, in step S306, the control unit (170) can generate a control signal to control the carbon monoxide concentration inside the chamber (A) according to the transmitted COHb concentration value. In this step, the control unit (170) can determine whether the COHb concentration value is greater than or less than a preset value, and generate a control signal for controlling the carbon monoxide concentration corresponding to the determination result.

[0159]

[0160] FIG. 4 is an operation flowchart of a method for automatically controlling the carbon monoxide concentration of a carbon monoxide high-pressure chamber according to one embodiment of the present invention.

[0161] Referring to FIG. 4, first, in step S401, operating conditions of the carbon monoxide high-pressure chamber may be set. The conditions set in this step may include a target carbon monoxide hemoglobin (COHb) concentration range or value, chamber operating time, termination conditions, etc.

[0162] Next, in step S402, a pressurized environment with a pressure higher than atmospheric pressure can be created inside the chamber according to the set conditions.

[0163] Next, in step S403, a gas containing carbon monoxide can be supplied into the chamber.

[0164] Next, in step S404, the carbon monoxide hemoglobin (COHb) concentration of the user inside the chamber can be measured. In this step, the COHb concentration can be measured continuously or discontinuously, and can be measured in an invasive or non-invasive manner.

[0165] Next, in step S405, it can be determined whether the COHb concentration measured in step S404 is greater than or equal to the range or value set in step S401. If the measured COHb concentration is greater than or equal to the set range or value, a control action to reduce the carbon monoxide concentration inside the chamber may be performed, and this concentration reduction action may correspond to step S405-1. If the measured COHb concentration is not greater than or equal to the set range or value, the process may proceed to the next determination step.

[0166] Here, step S405-1 is a branching operation performed selectively only when the COHb concentration exceeds a set upper limit condition, and may include an operation to reduce the carbon monoxide concentration inside the chamber to prevent symptoms of carbon monoxide poisoning. For example, the supply of a gas containing carbon monoxide may be reduced, or the supply of a gas not containing carbon monoxide may be maintained or increased.

[0167] Next, in step S406, it can be determined whether the measured COHb concentration is below a set range or value. If the measured COHb concentration is below the set range or value, a control operation to increase the carbon monoxide concentration inside the chamber may be performed, and this concentration increase operation may correspond to step S406-1. If the measured COHb concentration is not below the set range or value, the process may proceed to the next step.

[0168] Here, step S406-1 is a branching operation that is selectively performed only when the COHb concentration is below a set lower limit condition, and may include an operation to increase the carbon monoxide concentration inside the chamber to provide the therapeutic effect of carbon monoxide to the user inside the chamber. For example, it may be performed in such a way that the supply of a gas containing carbon monoxide is maintained or increased.

[0169] Finally, in step S407, it can be determined whether the set time has been reached or whether the set termination condition has been satisfied. If the set time has been reached or the termination condition has been satisfied, the entire control operation may be terminated. If the set time has not been reached or the termination condition has not been satisfied, the process may return to step S404 to repeatedly perform the COHb concentration measurement and condition determination process.

[0170]

[0171] FIG. 5 is a flowchart illustrating the entire process of a method for controlling the concentration of carbon monoxide in a high-pressure carbon monoxide chamber according to one embodiment of the present invention.

[0172] Referring to FIG. 5, first, in step S501, a step of making the pressure inside the chamber higher than atmospheric pressure can be performed. In this step, the inside of the chamber can be formed into a pressure state higher than atmospheric pressure according to preset pressure conditions, and subsequently, a pressurized environment in which a gas including carbon monoxide can be supplied can be created.

[0173] Next, in step S502, a step of supplying a gas containing carbon monoxide into the chamber may be performed. The gas supplied in this step may be a single-component gas containing carbon monoxide or a mixed gas containing carbon monoxide and other gaseous components, and may be introduced into the chamber through a supply passage.

[0174] Next, in step S503, a step of measuring the carbon monoxide concentration inside the chamber may be performed. In this step, the concentration of carbon monoxide present in the internal space of the chamber may be measured, and the measured carbon monoxide concentration may be generated as a value representing the gas composition state inside the chamber.

[0175] Next, in step S504, a step of measuring the carbon monoxide hemoglobin (COHb) concentration of the user inside the chamber may be performed. In this step, the COHb concentration may be measured as an indicator representing the degree of binding of carbon monoxide and hemoglobin within the user's body, and the measurement may be performed continuously or discontinuously.

[0176] Finally, in step S505, a step of controlling the carbon monoxide concentration inside the chamber may be performed. In this step, the carbon monoxide concentration inside the chamber may be controlled according to the carbon monoxide hemoglobin concentration value measured; for example, if the measured COHb concentration is above a preset value, an action to lower the carbon monoxide concentration inside the chamber may be performed, and if the measured COHb concentration is below a preset value, an action to raise the carbon monoxide concentration inside the chamber may be performed. Additionally, if the measured COHb concentration falls within a preset range, the carbon monoxide concentration inside the chamber may be controlled to be maintained.
