Description

Technical Field

[0001] The patent of this invention relates to the field of hyperbaric oxygen therapy, especially the effect of weightless diving in a closed high-pressure environment on physical rehabilitation treatment. Background Art

[0002] The hyperbaric oxygen zero-gravity rehabilitation treatment chamber is a large-scale innovative device. Its hyperbaric oxygen therapy technology is similar to that of an air chamber. Zero-gravity rehabilitation technology utilizes internationally recognized aquatic rehabilitation principles, following evidence-based scientific technology. This innovative device utilizes specialized technologies to comprehensively optimize its functionality.

[0003] The modern hyperbaric oxygen chamber's design was essentially finalized in the 1960s. Its core is a cylindrical, sealed container, large enough to accommodate a dozen people, while smaller ones can only accommodate one person lying down. This cylinder is pressurized to a maximum of 6 atmospheres (larger ones are pressurized with air), and the person inside wears a mask to breathe the pressurized oxygen.

[0004] Hyperbaric oxygen therapy involves breathing pure or highly concentrated oxygen at high pressure (above normal pressure). This is particularly true in an air chamber, where the oxygen is nearly 100% pure, compared to the 30% to 50% concentration of standard oxygen. The pressure inside a hyperbaric chamber is typically 1.6 to 2.5 atmospheres, equivalent to the pressure experienced by a person diving at a depth of 6 to 15 meters.

[0005] Hyperbaric oxygen therapy, as a mature treatment, is widely used in medical emergencies such as non-healing wounds, infections, stroke, sudden deafness, severe anemia, carbon monoxide poisoning, and decompression sickness. Hyperbaric oxygen therapy has shown great potential in improving cognition, inhibiting intrinsic skin aging and photoaging, improving glucose metabolism, enhancing myocardial and lung function, and preventing bone and muscle loss, among other hallmarks of aging.

[0006] Hyperbaric oxygen therapy (HBO) effectively increases plasma dissolved oxygen content and arterial oxygen partial pressure by providing a high-pressure, oxygen-rich, enclosed environment, inducing widespread biochemical and physiological changes throughout the body. Numerous mechanistic studies have reported that HBO therapy promotes tissue homeostasis and regeneration, promoting angiogenesis, reducing inflammation, enhancing antioxidant defenses, and stimulating stem cells.

[0007] The targets of hyperbaric oxygen (HBO) in the body overlap significantly with those of age-related diseases. Long-term or repeated intermittent HBO therapy is believed to increase cellular antioxidant capacity and delay cell aging.

[0008] Aquatic rehabilitation therapy leverages the physical properties of water to improve a patient's body structure and function, mobility, and participation through targeted treatment. It is widely used in neurological disorders, musculoskeletal disorders, geriatric conditions, and other areas. Its application continues to expand, with promising clinical results. Published literature also covers chronic fatigue syndrome, vestibular rehabilitation after peripheral nerve injury, autism spectrum disorder, attention deficit hyperactivity disorder (ADHD), breast cancer surgery, psychiatric rehabilitation, and maternal and infant rehabilitation.

[0009] When the human body is immersed in water, the physical properties of water produce a series of biological effects on the body, thereby affecting the circulatory, respiratory, musculoskeletal, and endocrine systems. This is the basis for the effectiveness of aquatic rehabilitation therapy. In recent years, relevant literature has been published on the effects of aquatic rehabilitation therapy on cerebral blood flow, cardiovascular response, metabolism, immune function, and neuroplasticity. Research results show that aquatic rehabilitation therapy can help regulate blood lipids, increase nerve growth factor concentrations, improve blood sugar levels, and improve cognitive function. It has a certain therapeutic effect on patients with obesity, hyperlipidemia, and hyperglycemia. In addition, aquatic rehabilitation is an effective lifestyle intervention strategy that can improve immune function and emotional state, and alleviate psychological and emotional issues such as anxiety and depression.

[0010] Aquatic rehabilitation therapy can significantly improve cardiopulmonary function, providing an ideal environment for cardiopulmonary training. Aquatic rehabilitation is a safe and effective rehabilitation method, highly effective in improving physical function. This is due to the physical properties of the water: buoyancy provides weight loss and support, while warmth promotes limb relaxation, relieves pain, and reduces anxiety and psychological tension. Water of varying temperatures, pressures, and solute content acts on the human body in various ways to achieve therapeutic effects. Water contains a variety of stimuli, producing significant therapeutic effects, both locally and systemically, on the skin, musculoskeletal system, cardiovascular system, respiratory system, nervous system, endocrine system, and on the recovery from fatigue.

[0011] By stimulating the peripheral nerves, it can affect the functions of the central nervous system and internal organs, achieving the following effects: anti-inflammation, fever reduction, analgesia, sedation, hypnosis, excitement, sweating, diuresis, reducing muscle and ligament tension, relieving spasms, promoting metabolism, and improving the regulatory function of the nervous system. The pressure in the water can also help patients with chronic respiratory diseases strengthen their lung ventilation function.

[0012] Invention patent content (technical solution)

[0013] The hyperbaric oxygen zero-gravity rehabilitation treatment chamber is a large-scale equipment. The most advanced technology is comprehensively adopted to restore the optimal environmental state of hyperbaric oxygen rehabilitation treatment. The main cabin of the patented equipment of this invention is a fully enclosed structure, and the main cabin is filled with rehabilitation fluid containing different solutes. The main cabin is equipped with a circulating breathing system, a constant temperature system, an emergency decompression system, and an external relay storage tank and a pressurization system. The circulating breathing system can be designed for hyperbaric oxygen, and can realize the continuous supply and monitoring of hyperbaric oxygen breathing under different pressures. After the rehabilitation personnel enter the main cabin, they gradually enter a weightless suspension state with the injection of rehabilitation solution. The hyperbaric oxygen zero-gravity rehabilitation treatment chamber simulates an amniotic fluid-like environment. To a certain extent, it reproduces the temperature, pressure, gravity, aerobic regeneration of body tissues and other conditions of the fetus in amniotic fluid.

[0014] The main cabin is constructed of 316L stainless steel and is oval in shape. A door at one end can be fully opened. Rehabilitation therapists enter the main cabin in a supine position on a support bed. The cabin is fully sealed and pressurized, capable of withstanding loads up to 6 atmospheres. Observation windows at various angles are located vertically and horizontally along the main cabin walls. The cabin is equipped with waterproof and pressure-resistant LED lighting. The interior of the main cabin is a 2m x 1m cylindrical volume, large enough to accommodate an adult with ample room for movement.

[0015] A rebreathing system is a breathing circuit consisting of the human lungs; a gas supply cylinder (pure oxygen and diluent); a breathing bag; a diving mask with a regulator; piping; a carbon dioxide adsorption tank; and control components (electronic valves, oxygen sensors, computers, etc.). Gas circulates continuously in a single direction through the circuit. Oxygen consumed by the human body is replenished from the pure oxygen cylinder. The carbon dioxide adsorption tank, in a fully closed rebreather, uses a CO2 absorbent to absorb CO2 from the exhaled air of the occupant, allowing it to be re-breathed by the occupant, thus conserving breathing gas. The rebreathing system automatically mixes gases in real time, adjusting the oxygen ratio in the breathing gas. During pressurization or depressurization of the main chamber, the oxygen partial pressure remains constant while the partial pressure of the inert gas (typically nitrogen and helium) is simultaneously reduced. This maintains a constant high-pressure oxygen partial pressure, maximizing decompression efficiency, reducing decompression stops, and eliminating inert gas peaks that can cause isobaric back diffusion (IBCD).

[0016] The relay tank is a relay device used to prepare fluids for injection into the main chamber. Its capacity is 1.2 times that of the main chamber. The rehabilitation fluids in the chamber contain different solutes, which exhibit varying transdermal absorption properties at different temperatures. Transdermal absorption of traditional Chinese medicine liquids is widely used in clinical practice. The relay tank is equipped with a heating system, ultraviolet sterilization filter, and a circulating heat pump.

[0017] The main component of the pressurization system is the compressor that pressurizes the main cabin. It can guarantee a maximum pressure of 5 atmospheres (5 bar). A pressure-reduction control valve is also installed on the main cabin door, connecting the air compressor to the main cabin to control the rate of increase or decrease.

[0018] The constant temperature system features a carbon fiber heating device installed inside the main cabin with a backup temperature sensor. A temperature sensor monitors the cabin temperature in real time to maintain a constant temperature. When the temperature drops below the set point, the temperature automatically activates.

[0019] The emergency decompression system is a foot-operated emergency decompression device installed at the bottom of the main cabin. It can immediately open the pressure relief valve from inside the main cabin, discharging liquid solutes and reducing cabin pressure, allowing occupants to escape the liquid environment.

[0020] The working principle of the above technical solution is as follows

[0021] The atmospheric pressure within the sealed rehabilitation chamber gradually increases, and this pressure transmission causes the water pressure within the chamber to rise accordingly. Simultaneously, participants in the rehabilitation solution within the chamber begin inhaling compressed air with an oxygen content exceeding 21%. Under this high-pressure environment, the inhaled high-pressure oxygen air blends with the blood in the alveoli, increasing the blood oxygen content. This higher oxygen partial pressure in the blood effectively enhances the body's repair mechanisms, achieving the desired therapeutic effect.

[0022] At the same time, the high-pressure, constant-temperature liquid environment comprehensively stimulates nerve endings on the skin's surface, repairing damaged neurons. In the absence of gravity, blood flow to the center of the body's muscles accelerates, improving cardiac efficiency, including increased stroke volume and oxygen uptake, and decreased heart rate. This improves muscle strength, endurance, and flexibility. Energy consumption in water is greater than on land for the same period of time. The buoyancy of water reduces the force of gravity on the limbs, providing an ideal zero-gravity environment for rehabilitation. The reduced respiratory workload strengthens intercostal muscles, enhances respiratory muscle function, and further enhances exercise capacity. The zero-gravity environment can lower blood pressure to a certain extent, providing an optimal rehabilitation environment for patients with cardiovascular disease. The zero-gravity environment in water reduces joint burden, promotes blood flow to bones, improves bone nutrition and health, and accelerates bone and joint rehabilitation.

[0023] The beneficial effects of the present invention are

[0024] Inhaling compressed air with an oxygen content exceeding 21% in a high-pressure liquid environment can reduce the amount of dissolved nitrogen in the blood of rehabilitators, thereby alleviating fatigue. The hyperbaric oxygen zero-gravity rehabilitation therapy chamber increases blood oxygen content and oxygen partial pressure, thereby promoting oxygen distribution and utilization throughout the body. Combined with the constant temperature liquid environment, this stimulates the nervous system, muscle tissue, and skeletal joints, enabling rapid physiological and chemical changes to achieve the goal of rehabilitation therapy.
