Description

Technical Field

[0001] This invention relates to the field of hydrogen-oxygen therapy technology, and more particularly to a micro-pressure hydrogen-oxygen therapy chamber. Background Technology

[0002] Hydrogen (H2) molecules are nonpolar molecules linked by covalent bonds and possess stable chemical properties at room temperature. Their extremely low molecular weight promotes unparalleled membrane permeability and systemic diffusion, making them a valuable therapeutic agent for a variety of pathologies. They have been shown to be used to treat cancer, stroke, ischemic injury, Alzheimer's disease, atherosclerosis, diabetes, hepatitis, colitis, pancreatitis, arthritis, and other conditions.

[0003] Currently, hydrogen delivery methods in hydrogen therapy include inhaling hydrogen, hydrogen-rich water, injecting hydrogen-rich saline, hydrogen baths, and oral hydrogen-producing capsules. However, due to the low water solubility of hydrogen, it is difficult for hydrogen to accumulate deep within the lesion, making precise delivery difficult. This greatly affects the therapeutic effect of traditional hydrogen in complex disease environments.

[0004] The therapeutic effects of microbarotherapy chambers have now been widely adopted in hospitals and community health centers, and have been proven to have good effects on respiratory, cardiovascular, wound healing, poisoning, and rapid fatigue recovery. It mainly utilizes the microbarotherapy environment to increase the amount of dissolved oxygen, increase tissue oxygen reserves, and enhance oxygen diffusion capacity.

[0005] Currently, most micro-hyperbaric oxygen chambers on the market use nasal cannula breathing methods, resulting in high concentrations and dryness of inhaled oxygen. This leads to oxygen poisoning in some users, causing symptoms such as dryness and itching in the lungs and trachea, and coughing. Furthermore, the low concentration of oxygen in the environment prevents oxygen from penetrating deep tissues through skin cells to activate cell metabolism, so improvements are needed. Summary of the Invention

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing a micro-pressure hydrogen-oxygen therapy chamber.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: A micro-pressure hydrogen-oxygen therapy chamber includes a micro-pressure hydrogen-oxygen chamber body, wherein a high-pressure air inlet pipe and an oxygen inlet pipe are provided on one side of the micro-pressure hydrogen-oxygen chamber body, and a humidification micro-pressure mechanism is provided on the high-pressure air inlet pipe and the oxygen inlet pipe. The micro-pressure hydrogen-oxygen chamber is equipped with a control system and a hydrogen generator, and a hydrogen concentration sensor and an oxygen concentration sensor are also installed inside the micro-pressure hydrogen-oxygen chamber. The micro-pressure hydrogen-oxygen chamber is equipped with a manual exhaust valve and two electrically controlled exhaust valves. The high-pressure air intake pipe and oxygen intake pipe are both equipped with purification mechanisms on the side near the micro-pressure hydrogen-oxygen chamber, and the purification mechanisms are all connected to the micro-pressure hydrogen-oxygen chamber. The micro-pressure hydrogen-oxygen chamber is equipped with temperature control equipment and pressure sensors.

[0008] Compared with existing technologies, this application can achieve the input of appropriate low-concentration hydrogen and high-concentration oxygen into the micro-pressure hydrogen-oxygen chamber according to the patient's needs. Moreover, it can achieve the micro-pressure effect within the micro-pressure hydrogen-oxygen chamber through the supply of compressed gas. This solves the safety issues of hydrogen and avoids the side effects of breathing mask-type oxygen inhalation through diffusion breathing and skin penetration. At the same time, under pressure, hydrogen can quickly pass through capillaries, blood-brain barrier and cell membrane to reach deep tissues through the permeation of skin cells, rapidly activate cell metabolism and improve the therapeutic and health care effects of oxygen and hydrogen.

[0009] Preferably, the humidification micro-pressure mechanism includes two humidification bottles, one of which is connected to the high-pressure air inlet pipe and the other to the oxygen inlet pipe at the end away from the micro-pressure hydrogen-oxygen chamber.

[0010] Furthermore, the humidification bottle can effectively purify, cool, and humidify oxygen and compressed air, making the gas in the micro-pressure hydrogen-oxygen chamber fresh, with suitable temperature and humidity, which is convenient for patients entering the micro-pressure hydrogen-oxygen chamber to receive oxygen and hydrogen.

[0011] Preferably, the purification mechanism includes two purification box assemblies respectively connected to a high-pressure air inlet pipe and an oxygen inlet pipe.

[0016] Furthermore, the positioning rod can quickly define the position of the square frame, while the sealing gasket can effectively seal the gas and prevent leakage, ensuring that the gas flows through the clean-grade gas filter assembly. Moreover, the clean-grade gas filter assembly is an existing purification component that can effectively filter and purify tiny impurity particles in the gas, thus significantly improving the gas quality.

[0017] Preferably, the closing mechanism includes an inspection cover hinged to the other side of the upper end of the purification box assembly, the inspection cover having a notch, and a knob rotatably connected to the upper end of the purification box assembly, the notch and the knob corresponding to each other.

[0018] Furthermore, the operator can rotate the inspection cover so that the notch on the inspection cover can pass through the knob on the purification box assembly. At the same time, the knob can be rotated and pressed against the upper end of the inspection cover. Meanwhile, a rubber pad component is installed at the lower end of the inspection cover, which can be squeezed to prevent leakage.

[0020] Furthermore, the directional gas delivery component can extract gas from the purification chamber component and ensure that the prepared oxygen and compressed air enter the micro-pressure hydrogen-oxygen chamber to increase the pressure inside the chamber, so that the hydrogen and oxygen can be absorbed by the patient.

[0021] Preferably, the top of the purification chamber has an opening, and the inspection cover corresponds to the opening.

[0022] Furthermore, it facilitates the replacement of clean-grade gas filter components to ensure purification operations.

It can greatly improve its physical solubility in blood and body fluids, increase the body's tissue reserves, and enable it to quickly pass through capillaries, the blood-brain barrier, and cell membranes; 2. It can significantly increase the diffusion rate and effective diffusion distance of gases in the blood under the influence of gas tension, enabling hydrogen and oxygen to reach deep into the lesion. This greatly enhances the therapeutic and health-promoting effects of oxygen and hydrogen. 3. Low-concentration and safe hydrogen, and high-concentration oxygen, through diffusion respiration and skin penetration, not only solves the safety problem of hydrogen, but also avoids the side effects of oxygen inhalation mask. At the same time, under pressure, it can reach deep tissues through skin cell penetration and quickly activate cell metabolism. 4. It can purify the gas through the purification box components and its internal parts, ensuring gas quality and making it better absorbed and used by patients. Attached Figure Description
