Description

Technical Field

[0001] This invention relates to the field of health technology, and in particular to an adaptive control method and system for oxygen chambers. Background Technology

[0002] In the field of human antioxidant anti-aging, the market mainly uses supplements. While these may offer good temporary relief in severe or emergency situations, they tend to downplay the impact of side effects. However, for daily health maintenance or the management of some chronic diseases, maintaining a low dosage often fails to achieve significant results and carries certain side effects, resulting in a situation where the benefits outweigh the risks for the user. This is because supplements have two main problems: firstly, it's difficult to achieve antioxidant effects without mitigating other physiological negative impacts; secondly, because they are ingested, it's difficult for them to reach the target tissues and organs to exert their effects.

[0003] Another approach to anti-oxidation is physical conditioning, which involves stimulating certain functions of the body through magnetic, electrical, or wave methods to achieve the expected goal of anti-oxidation and anti-aging. However, these approaches are difficult to explain and confirm from a scientific perspective, making it hard for users to distinguish whether they are effective or just psychological effects that may produce a feeling of well-being.

[0004] During aerobic metabolism in the human body, a certain amount of free radicals are inevitably produced. These free radicals participate in certain physiological processes and are not entirely harmful. The human body also possesses mechanisms to combat free radicals, which, under normal circumstances, can effectively limit their numbers to ensure safety and health. However, human activity environments, habits, diets, and many other factors are too complex. Factors such as weakness, lack of sleep, and illness can all lead to the production of large amounts of free radicals. In these situations, the body's tissue functions are limited, and its antioxidant mechanisms cannot effectively control the number of free radicals in a timely manner, thus triggering a series of cell damages and even diseases, accelerating the oxidative aging process.

[0005] In the field of civilian hyperbaric oxygen chambers, the main product parameter settings on the market are chamber pressure and oxygen flow rate. Even when people of different groups, different physical conditions, and different health statuses use these two parameters to provide pressure oxygen inhalation services, this has caused discomfort to a wide range of users. Summary of the Invention

[0006] The purpose of this invention is to provide an adaptive control method and system for oxygen chambers to solve the problem of discomfort experienced by a large number of users due to existing oxygen chamber operation methods.

[0049] K = ηa × K(org)

[0050] Pmax = ηa × P(σ). ....P(σ) is the safety allowable limit.

[0051]

[0052] Ox% = ηa × 100%

[0053] Optionally, in the aforementioned oxygen chamber adaptive control method, adjusting the initial adjustment parameters of the chamber pressure and / or the initial adjustment parameters of the human body's inhaled oxygen to adaptive parameters of the chamber pressure and / or the human body's inhaled oxygen based on the feedback data on changes in vital signs further includes:

[0071] The oxygen generation system is configured to operate according to the initial adjustment parameters of human inhaled oxygen, or according to the adaptive parameters of human inhaled oxygen.

[0072] The inventors of this invention discovered through research that, during the operation of existing oxygen chamber systems, different users, limited by their own physical conditions, have varying degrees of acceptance, tolerance, and physical sensations regarding pressurized oxygen. This results in users experiencing either insufficient oxygen or discomfort, significantly reducing the effectiveness of the system and even causing users to develop a negative attitude towards it.

[0073] This result is because the existing oxygen chamber system, with its inherent pressure oxygen parameters, is not rationally designed for different populations; it is merely a compromise solution adopted due to limitations in technology or other economic factors.

[0074] On the other hand, existing technologies do not take into account the superficial regulation of human oxygen inhalation, the impact on the perception of temperature, humidity, and pressure on the body surface placed in the oxygen chamber, and the impact of human oxygen inhalation flow rate, pressure, temperature, and humidity on the respiratory tract and internal perception. These two types of internal and external perceptions are different and need to be treated differently. Only by carefully and reasonably adjusting each parameter can a better overall user experience be obtained.

[0075] Based on the above research, this invention proposes an adaptive control method and system for a hyperbaric oxygen chamber. By adjusting the initial adjustment parameters of the chamber pressure (and / or inhaled oxygen) to adaptive parameters based on feedback data of changes in vital signs, this invention enables adaptive configuration and adjustment of pressurized air and pressurized oxygen based on user vital sign data in a micro hyperbaric oxygen chamber, as well as timely adjustment of oxygen supply parameters and oxygen supply strategy based on user vital sign data.

[0137] One embodiment of the present invention comprises a detection unit located within a manned cabin 101, a configuration modulation terminal 106 located within an equipment compartment 102, a unit control terminal 161, and a background adaptive computing system 105. The detection unit within the manned cabin 101 mainly consists of an environmental parameter detection unit 103 and a non-invasive vital sign detection unit 104. The environmental parameter detection unit 103 includes an ambient temperature detection unit 131, an ambient pressure detection unit 132, and an ambient humidity detection unit 133. The real-time detection of the manned cabin's environmental parameters communicates with the background adaptive computing system 105.

[0138] The non-invasive vital sign monitoring 104 includes at least blood oxygenation detection 141, body temperature detection 142, and heart rate detection 143. The real-time data collected is transmitted to the background adaptive computing system 105, where the adaptive algorithm matches and generates the environmental parameters and pressure oxygen configuration parameters that need to be optimized and controlled, and modulates the corresponding parameters through the configuration modulation terminal 106.

[0139] The pressure system 107 consists of a booster air intake filter 171, a booster compressor 172, a booster filter 173, a booster pressure sensor 174, and a booster temperature sensor 175. The parameters from the booster pressure sensor 174 and the booster temperature sensor 175 are provided to the configuration modulation terminal 106 and participate in control calculations. The boosted air passes through the air conditioning evaporator 193 in the environmental control system 109 as needed to regulate its temperature. The prepared pressurized air is then distributed and controlled by the configuration modulation terminal 106 via the booster / environmental control path 115.

[0140] The oxygen generation system 108 consists of an oxygen intake filter 181, an oxygen compressor 182, a controllable reversing valve 183, a molecular sieve 184, a controllable cooler 185, a compressed oxygen temperature sensor 186, and a compressed oxygen concentration and flow rate sensor 187.

The controllable reversing valve 183 and the controllable cooler 185 are controlled by the configuration modulation terminal 106 through the unit control execution path 162. The compressed oxygen produced by the oxygen generation system 108 is fed to the configuration control terminal 106 via the compressed oxygen control path 114 for further parameter modulation and subsequent distribution.

[0141] The environmental control system 109 consists of an air conditioning compressor 191, an air conditioning condenser 192, and an air conditioning evaporator 193. Its temperature control within the manned cabin 101 is primarily achieved through the temperature control of the pressurized air passing through the air conditioning evaporator 193 via the pressurization system 107. It controls the air temperature supplied to the manned cabin 101 environment via the pressurization / environmental input path 111 and simultaneously dehumidifies it.

[0142] The configuration modulation terminal 106 integrates the detection data input from the pressure system 107, oxygen generation system 108, and environmental control system 109, and performs parameterized control on the actuators in these subsystems. The configuration modulation terminal 106 supplies pressurized air and pressurized oxygen generated by the aforementioned systems through the pressurization / environmental control path 115 and the pressurized oxygen control path 114, respectively. The pressurized air is dynamically controlled via the distribution valve group 163 and supplied to the manned cabin 101 via the pressurization / environmental input path 111. The pressurized oxygen gas is humidified via the controllable humidification section 166, and the controllable cooler 185 is controlled via the unit control execution path 162, thereby achieving temperature control of the pressurized oxygen. After being modulated by the controllable temperatureization section 166, the pressurized oxygen undergoes controllable partial ionization via the ionization section 167 to increase the content of negative oxygen ions. The specific control process is combined with the aforementioned background adaptive computing system 105. After the partial state control of the pressurized oxygen is completed, it is sent to the manned cabin 101 via the configuration pressurized oxygen input path 112.

[0143] The configuration modulation terminal 106, via a pressure relief / ventilation output path 113, can release pressurized air from the manned cabin 101 to the outside via an exhaust path 116 to regulate the cabin pressure. Through the adjustment of the flow control valve assembly 164, it can adaptively ventilate the cabin as needed to control humidity and air freshness. A safety valve assembly 165 is connected in parallel to the pressure relief / ventilation output path 113 to constrain its pressure regulation range within a safe range, preventing control failure due to equipment electrical system malfunctions or other reasons.

[0144] This invention proposes an oxygen chamber system. A vital signs detection terminal 104 detects the vital signs parameters of the human body inside the chamber. A control terminal acquires pressure parameters and commands, as well as oxygen production parameters and commands, based on these vital signs parameters. A pressure system 107 adjusts the air pressure inside the chamber according to the pressure parameters and commands, and an oxygen production system 108 adjusts the flow rate of oxygen inhaled by the human body inside the chamber according to the oxygen production parameters and commands. This system enables adaptive configuration and adjustment of pressurized air and pressurized oxygen based on user vital signs data in a micro-hyperbaric oxygen chamber, as well as timely adjustment of oxygen supply parameters and oxygen supply strategies based on user vital signs data.

[0145] The oxygen chamber system provided by this invention modulates parameters of inhaled oxygen based on real-time human vital signs data, and adjusts environmental control parameters under pressure changes. This not only fully mobilizes the body's biological responses, enhancing product functionality, but also significantly reduces discomfort during use. Based on individual physical differences, different pressure oxygen supply parameters and environmental parameters are optimized to eliminate negative impacts and regulate physiological balance while ensuring the body's tolerance, resulting in more personalized effects. Simultaneously, the system adaptively enhances the body's own antioxidant mechanisms, achieving anti-oxidative aging through purely physical regulation.

[0146] This invention provides an oxygen chamber control system, such as Figure 4 As shown, it includes: a detection device (i.e., a vital sign detection terminal 104), configured to acquire vital sign data of a human body inside the chamber; a pressure system, configured to cause the air pressure inside the chamber to sequentially pass through a pressurization cycle, a pressure fluctuation cycle, and a depressurization cycle in one operating cycle; an oxygen generation system, configured to cause the oxygen concentration of oxygen inhaled by the human body to pass through at least one of an oxygen concentration rise cycle and / or an oxygen concentration maintenance cycle and / or an oxygen concentration fall cycle in one operating cycle; and a control terminal, configured to set at least one of the operating time, operating parameter amplitude range, and operating parameter fluctuation gradient rate of the pressurization cycle and / or the pressure fluctuation cycle and / or the depressurization cycle based on the vital sign data; and / or to set at least one of the duration, oxygen concentration change amplitude range, and oxygen concentration change gradient rate of the oxygen concentration rise cycle and / or the oxygen concentration maintenance cycle and / or the oxygen concentration fall cycle based on the vital sign data.

[0147] In one embodiment of the present invention, the oxygen chamber control system is further configured such that: the operating time of the pressurization cycle coincides with the duration of the oxygen concentration rise cycle; and / or the operating time of the pressure fluctuation cycle coincides with the duration of the oxygen concentration maintenance cycle; and / or the operating time of the depressurization cycle coincides with the duration of the oxygen concentration fall cycle.

[0148] In one embodiment of the present invention, the oxygen chamber control system is further configured to: ionize the inhaled oxygen during the depressurization cycle, so that the inhaled oxygen contains negative oxygen ions, until the depressurization cycle ends; the concentration of negative oxygen ions during the depressurization cycle is 20,000 / cm³. 3 -100,000 / / cm 3 between.

[0149] In one embodiment of the present invention, the oxygen chamber control system is further configured such that the pressurization cycle includes: causing the air pressure inside the chamber to rise slowly and uniformly, and stopping the rise of air pressure inside the chamber after pressurizing to a first air pressure threshold; during the pressurization cycle, the oxygen concentration of oxygen inhaled by the human body rises slowly and uniformly to a first oxygen concentration threshold and is maintained; wherein the running time of the pressurization cycle and / or the first air pressure threshold and / or the first oxygen concentration threshold are obtained based on vital sign data.

[0150] In one embodiment of the present invention, the oxygen chamber control system is further configured such that the pressure fluctuation cycle includes: causing the pressure inside the chamber to periodically fluctuate around a first pressure threshold; obtaining the running time of the pressure fluctuation cycle and / or the range of pressure fluctuation amplitude and / or the pressure fluctuation gradient rate based on vital sign data; and maintaining the oxygen concentration of the oxygen inhaled by the human body at a first oxygen concentration threshold.

[0151] In one embodiment of the present invention, the oxygen chamber control system is further configured such that the depressurization cycle includes: causing the air pressure inside the chamber to periodically fluctuate and decrease, and stopping the decrease in air pressure inside the chamber after the pressure decreases to a second air pressure threshold; during the depressurization cycle, causing the oxygen concentration of the oxygen inhaled by the human body to periodically fluctuate with the air pressure trend from a first oxygen concentration threshold to a second oxygen concentration threshold and maintain it; wherein the running time of the depressurization cycle and / or the time of each periodic fluctuation decrease and / or the range of air pressure decrease amplitude and / or the air pressure decrease gradient rate and / or the second air pressure threshold and / or the second oxygen concentration threshold are obtained based on vital sign data.

[0152] In one embodiment of the present invention, in the oxygen chamber control system, such as Figure 5 As shown, the oxygen chamber control system is also configured to include 3 to 5 operating cycles during a single use of the oxygen chamber; when the oxygen chamber is started, it directly enters the pressurization cycle of the first operating cycle; in the last operating cycle, the air pressure inside the chamber directly drops to the standard atmospheric pressure, and the oxygen concentration inhaled by the human body directly drops to the air oxygen concentration.

[0153] In one embodiment of the present invention, the oxygen chamber control system is further configured such that: the operating time of the pressurization cycle is 10-60 minutes; the pressure range of the pressurization cycle is between 1.05 ATM and 1.9 ATM, and the pressurization gradient rate is between 5 KPA / MIN and 10 KPA / MIN; and the first oxygen concentration threshold of the pressurization cycle is between 50% and 100%.

[0154] In one embodiment of the present invention, the oxygen chamber control system is further configured such that: the operating time of the pressure fluctuation cycle is 15-60 minutes, and each pressure fluctuation cycle has at least two periodic fluctuations with pressure fluctuation amplitudes ranging from 5KPA to 30KPA, and the pressure fluctuation gradient rate is between 5KPA / MIN and 10KPA / MIN; the oxygen concentration of the oxygen inhaled by the human body is maintained between 50% and 100% during the pressure fluctuation cycle.

[0155] In one embodiment of the present invention, the oxygen chamber control system is further configured such that: the depressurization cycle runs for 10-60 minutes, and each depressurization cycle has at least two periodic pressure drops with an amplitude range between 5 kPa and 20 kPa, the pressure drop gradient rate for each cycle is between 5 kPa / min and 10 kPa / min, and the pressure drop gradient rate for the entire cycle is between 5 kPa / min and 10 kPa / min; during the depressurization cycle, the oxygen concentration inhaled by the human body decreases from a first oxygen concentration threshold to the air oxygen concentration.

[0156] In one embodiment of the invention, targeting individuals with poor basic physical fitness, their vital signs, heart rate, and blood oxygen saturation are monitored in real time. An adaptive algorithm is used to determine the applicable maximum pressure (Pmax), and combined with blood oxygen saturation feedback, an applicable maximum oxygen concentration range (Ox%) is provided. One operating cycle lasts at least 30 minutes, including a complete operating cycle T3. The allowable pressure ramp-up / prolapse rate (KPA / MIN) is calculated using the adaptive algorithm, and the operating time T1 of the ramp-up cycle is Pmax / K. During this stage, the oxygen concentration inhaled by the human body increases to the maximum value (Ox%) at a gradient rate of (Ox% - 21%) / T1. This stage is primarily an adaptation testing phase, determining a physiologically suitable adjustment range for the user, gradually increasing blood oxygen content, and assessing the body's adaptation and regulation under pressure.

[0157] After completing the pressurization cycle, the system enters a pressure fluctuation cycle, with the pressure fluctuation amplitude ranging from 0.5Pmax to 1Pmax. The value is Pn according to the adaptive algorithm. The pressure fluctuation gradient rate is consistent with the allowable pressurization / depressurization gradient rate. Based on vital sign feedback, 2-10 fluctuation cycles are selected, with a fluctuation number of q. The stage duration is T2-T1 = (2XPn / K)X q, and a single fluctuation cycle Ta = (T2-T1) / q. During this stage, the oxygen concentration maintains the aforementioned high value of 0x%. This stage uses pressure fluctuations to repeatedly increase and decrease blood oxygen content. After tissue oxygenation is replenished, controlled, low-level ROS stimulation is used to activate the antioxidant mechanism within the mitochondria.

[0158] After completing the pressure fluctuation cycle, a depressurization cycle begins. The fluctuation amplitude is set to Pd using an adaptive algorithm, and the overall pressure decay rate is Ku = 0.2-1K (KPA / MIN). This means the overall duration of the depressurization phase is longer than the pressure rise phase, and the number of fluctuation adjustments is 2-10 fluctuation cycles. The total duration of this phase is T3-T2 = Pmax / Ku. During this depressurization cycle, the oxygen concentration decreases at a rate of (Ox%-21%) / (T3-T2) until it reaches normal levels. At the beginning of the depressurization cycle, the adaptive algorithm, along with the specific values ​​of Pmax and Ox% for this cycle, determines the input ionized oxygen concentration, with a range of 20,000 / cm³. 3 -100,000 / / cm 3 Between these two phases, the body adapts to the natural environment during this period of fluctuation, allowing its physiological functions to return to normal. This process eliminates the effects of free radicals from the conditioning phase but stimulates the balance of antioxidant mechanisms, thus returning to a natural state with a stronger ability to balance free radicals.

[0159] In one embodiment of the present invention, the target group is an individual with relatively good health and overall physical condition, whose own antioxidant mechanism has a strong capacity, but may experience some decline due to factors such as lifestyle and diet. In this case, a relatively long adjustment period is required to truly stimulate their own antioxidant balance mechanism.

[0160] Within one conditioning cycle, there are n (n<=10) regulation cycles. The specific individual regulation cycle is consistent with Example 1. In the depressurization adjustment phase of the intermediate cycle, the target pressure is not the end point of the single regulation cycle, i.e., normal pressure, but a value Pnx given by the adaptive algorithm, which ranges from 0.2 to 0.8Pmax. The strategies for oxygen supply and negative oxygen ion supply are the same as in Example 1.

[0161] In this embodiment, the intermediate cycle is T5-T4=(Pmax-Pnx) / K+(T2-T1)+(Pmax-Pnx) / Ku, and the total duration of the conditioning cycle is T6=T3+(N-1)*(T5-T4).

[0162] This invention provides an oxygen chamber control system that, based on vital sign data, sets at least one of the following: the operating time of the pressurization cycle and / or the pressure fluctuation cycle and / or the depressurization cycle; the range of operating parameter amplitudes; the rate of operating parameter fluctuations; the duration of the oxygen concentration rise cycle and / or the oxygen concentration maintenance cycle and / or the oxygen concentration fall cycle; the range of oxygen concentration changes; and the rate of oxygen concentration changes. This system enables the physical adjustment of specific parameters for oxygen supply to the human body and the flexible variation of the pressure in the conditioning space where the human body is located, thereby enhancing the body's own antioxidant mechanism.

[0163] The oxygen chamber control system provided by this invention can realize a method of physically regulating the human body's antioxidant mechanism, which is mainly achieved by adjusting the content of oxygen ingested by the human body, negative oxygen ions, and the pressure control of the human body's environment.

[0164] Compared with existing systems, the oxygen chamber control system proposed in this invention has the following advantages: During the pressurization cycle, the oxygen concentration is gradually increased to enhance the oxygen-carrying capacity of the blood and activate tissue function. Based on this, pressure fluctuations are used to adjust the ROS level within the body, further activating the antioxidant mechanism of the NRF2 pathway to achieve antioxidant balance and enhance antioxidant capacity. During the depressurization cycle, the influence of ROS levels during the conditioning period is eliminated through fluctuating attenuation and the effect of negative oxygen ions. As a purely physical method of regulation that directly mobilizes the body's own antioxidant mechanism, it possesses the advantages of being direct, efficient, and without side effects when adjusted according to individual physiological differences.
