Description

Technical Field

[0001] This invention relates to a hydrogen-rich physiotherapy product and its preparation method, belonging to the field of medical and health care technology. Background Technology

[0002] Joints and eyes are among the most frequently used parts of the human body. With rapid societal development, more and more people are experiencing knee, neck, and shoulder fatigue, which can lead to more serious health problems in the long run. Hot compress therapy is a good form of physical therapy, as it dilates blood vessels, improves local blood circulation, and promotes local metabolism, thus helping to relieve knee and cervical fatigue.

[0003] Currently, there are many heat therapy products on the market, such as a steam neck and shoulder patch disclosed in Chinese patent (CN109223299A) and a steam eye mask disclosed in Chinese patent (CN104622681A). However, the heat therapy products on the market are generally limited in function, that is, they only have the single function of heat therapy.

[0004] Studies have shown that hydrogen has anti-free radical properties, reduces inflammation in knee osteoarthritis, and alleviates cartilage damage in the knee joint. Therefore, hydrogen-based health therapy products are gaining increasing market attention. For example, Chinese patent (CN108294960A) discloses a hydrogen-rich beauty mask; Chinese patent (CN113855582A) discloses a magnesium powder slow-release hydrogen-rich material, whose hydrogen enrichment value is less than 300 ppb after soaking for one hour. However, most hydrogen-rich products suffer from low hydrogen release and slow release rates. Summary of the Invention

[0005] [Technical Issues]

[0006] (1) Existing hot compress products have limited functionality;

[0007] (2) Existing technologies for preparing hydrogen-rich products have problems such as low hydrogen release and slow release rate.

[0008] [Technical Solution]

[0009] To address the aforementioned issues, this invention incorporates natural medicinal plants and hydrogen-rich components (such as modified magnesium powder and modified magnesium hydride) into the hot compress product. This adds traditional Chinese medicine therapy and hydrogen therapy functions to the hot compress therapy, achieving multifunctionality. Furthermore, a unique surface coating material physically encapsulates the magnesium powder and magnesium hydride without affecting their physicochemical properties. This prevents the product from reacting with water and oxygen during storage and does not hinder the reaction of hot steam with the magnesium powder and magnesium hydride, thereby accelerating the release of hydrogen and its release rate.

[0010] The first objective of this invention is to provide a hydrogen-rich physiotherapy product, comprising a non-woven fabric cover, an impermeable membrane, a breathable membrane, a sterile fabric, a heating bag, and a hydrogen-rich bag; the heating bag is filled with a heating component and a natural medicinal plant component; the hydrogen-rich bag is filled with a hydrogen-rich component.

[0021] (3) Mix the propyl gallate solution and magnesium powder in step (1) and grind them. Then add the mixture from step (2) and continue grinding. After grinding, dry and cool to obtain modified magnesium powder.

[0030] Sodium chloride is dissolved in water to obtain an aqueous solution of sodium chloride;

[0031] Activated carbon, silica, volcanic rock, and superabsorbent resin are stirred in a mixer for 5-10 minutes. Then, sodium chloride aqueous solution is added to the mixer and stirred for 5-10 minutes. Natural medicinal plant components are then added and stirred for 5-10 minutes to obtain a mixture. Iron powder and vermiculite are added to the mixture and stirred for 5-10 minutes to obtain the functional heating component. The functional heating component is then packed into a bag to obtain a heating bag.

[0036] In one embodiment of the present invention, the hydrogen-rich physiotherapy product can be made into the desired shape as needed.

[0037] [Beneficial Effects]

[0038] (1) In this invention, propyl gallate is used as the main modifier to coat modified magnesium hydride and magnesium powder. Propyl gallate is poorly soluble in cold water but readily soluble in hot water. This physical property of propyl gallate has two beneficial effects: ① At room temperature, propyl gallate can protect magnesium hydride and magnesium powder from reacting with water, which helps to extend the shelf life of the product; ② When in contact with heated steam (during product use), the propyl gallate coating will fail, and the hot steam will react with the magnesium hydride and magnesium powder, rapidly releasing a large amount of hydrogen gas.

[0039] (2) The present invention places the hydrogen-rich component and the heating component into the hydrogen-rich bag and the heating bag respectively, which can more effectively protect the hydrogen-rich component and enable it to be stored for a long time.

[0040] (3) This invention combines heating therapy and hydrogen therapy. Heating can enlarge pores and promote blood circulation, which is conducive to the penetration of hydrogen into the body and to better realize the therapeutic function of hydrogen.

[0041] (4) This invention utilizes the health benefits of natural medicinal plants and hydrogen: Among them, the main effects of Piper kadsura are to dispel wind and dampness and unblock meridians; the main effects of Piper kadsura bark are to dispel wind and dampness, unblock meridians and relieve pain; the main effects of safflower are to invigorate blood circulation, unblock meridians and relieve pain; the main effects of Lycopodium clavatum are to dispel wind and dampness and relax muscles and tendons; the main effects of Cinnamomum cassia are to warm and unblock meridians and assist yang and qi; the main effects of Saposhnikovia divaricata are to dispel wind and release the exterior, eliminate dampness and relieve pain; the main effects of Digitaria sanguinalis, Cassia tora, mulberry leaf and honeysuckle are to relieve fatigue; the main effects of Chrysanthemum morifolium are to resist aging and reduce wrinkles; the main effects of Dendrobium nobile are to resist oxidation and repair; the main effects of hydrogen are to resist free radicals, anti-inflammation, and anti-apoptosis.
