Description

Technical Field

[0001] This utility model belongs to the field of hydrogen therapy technology, and more specifically, it relates to a hydrogen patch and a hydrogen patch device. Background Technology

[0002] Hydrogen molecules, due to their strong permeability and antioxidant properties, have been proven to have anti-inflammatory and anti-aging effects, thus hydrogen therapy technology is widely used in the healthcare field. In recent years, transdermal drug delivery technology has developed rapidly, and most similar products on the market are simple hydrogen-containing gel patches. Their hydrogen molecule release rate cannot be controlled according to user needs, the hydrogen release duration is short, and hydrogen is prone to leakage in the patch, resulting in poor hydrogen therapy effects. Utility Model Content

[0003] The purpose of this invention is to provide a hydrogen patch to solve the technical problems in the prior art, such as the inability to control the release rate of hydrogen molecules, the short release duration, and the easy leakage of hydrogen, which leads to poor therapeutic effects of hydrogen therapy.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is: to provide a hydrogen dressing, comprising:

[0005] The base membrane layer is made of a waterproof and airtight material; the base membrane layer is provided with an inlet and an outlet.

[0006] The permeable layer is made of a waterproof and breathable material, and its edges are sealed to the base film layer. The permeable layer is used to be applied to the affected area and permeates hydrogen gas toward the affected area. A receiving cavity is formed between the base film layer and the permeable layer. The inlet and outlet are connected to the receiving cavity.

[0007] The flow pipe is made of waterproof and breathable material and is fixedly installed in the receiving cavity; the flow pipe is arranged in a spiral pattern, and its two ends are respectively inserted into the inlet and the outlet.

[0008] Hydrogen gas enters the receiving cavity through the flow pipe located in the inlet, and the hydrogen gas passes through the flow pipe and the permeation layer to act on the affected area.

[0009] In one possible implementation, the permeation layer and the flow channel are integrally formed, with the flow channel protruding outward from one side of the permeation layer toward the base film layer.

[0010] In one possible implementation, the side of the flow channel away from the permeation layer is connected to the base membrane layer.

[0011] In one possible implementation, the flow pipe is provided with connecting pipe sections extending out of the receiving cavity at both ends, and the outer surface of the connecting pipe sections is provided with a sealing layer.

[0012] In one possible implementation, the flow channels are multiple and arranged side-by-side at intervals.

[0013] In one possible implementation, the base film layer is an aluminum film, and the permeation layer and the flow channel are made of polytetrafluoroethylene material.

[0014] In one possible implementation, the hydrogen patch further includes a sealing ring layer located on the side of the permeation layer away from the base film layer, the sealing ring layer being arranged along the edge of the permeation layer.

[0015] In one possible implementation, the hydrogen patch further includes breathing holes penetrating the base film layer and the permeable layer.

[0016] In one possible implementation, the flow pipe is provided with multiple hot water sections and multiple hydrogen sections, and the multiple hydrogen sections are respectively arranged between two adjacent hot water sections.

[0017] The beneficial effects of the hydrogen compress provided by this utility model are as follows: Compared with the prior art, when using the hydrogen compress of this utility model, the permeable layer of the hydrogen compress is first applied to the affected area requiring treatment, ensuring a tight fit. Then, hydrogen gas enters the flow channel from the inlet. Because the flow channel is arranged in a spiral pattern within the receiving cavity, the flow path and residence time of the hydrogen gas within the receiving cavity are increased. During the flow process, the hydrogen gas gradually diffuses into the receiving cavity through the waterproof and breathable material of the flow channel, and then passes through the permeable layer to act on the affected area, or the hydrogen gas directly passes through the permeable layer from the flow channel to act on the affected area. The remaining hydrogen gas is discharged from the outlet, completing one treatment process. In this way, the spiral arrangement of the flow channel prolongs the residence time of the hydrogen gas in the receiving cavity, allowing for a continuous and stable release of hydrogen gas; by controlling the input parameters of the hydrogen gas, the release rate of the hydrogen gas can be flexibly adjusted, achieving the goal of controlling the release of hydrogen molecules according to user needs. Furthermore, the waterproof and airtight properties of the base membrane layer, along with the sealed connection between the permeable layer and the base membrane layer, effectively reduce hydrogen leakage and ensure the concentration of hydrogen within the containment cavity, thereby enhancing the therapeutic effect of hydrogen.

[0018] Another objective of this utility model is to provide a hydrogen plastering device, including any of the above-mentioned hydrogen plasters, and further including a hydrogen inhaler, a hot water system, and a feed pipe. The feed pipe includes a main connecting pipe and two branch connecting pipes. One end of the two branch connecting pipes is connected to one end of the main connecting pipe, and the other end of the main connecting pipe is connected to the end of the flow pipe located in the inlet. The other ends of the two branch connecting pipes are respectively connected to the hydrogen inhaler and the hot water system. One end of the return water pipe is connected to the other end of the flow pipe.

[0019] This invention provides a hydrogen therapy device. By using a hydrogen patch, it organically combines the patch with a hydrogen inhalation machine, a hot water system, and a delivery pipe to construct a complete hydrogen therapy system. The hydrogen inhalation machine serves as the core hydrogen supply source, generating high-purity hydrogen. The hot water system provides constant-temperature hot water, and the two work collaboratively through the delivery pipe. The delivery pipe is a Y-shaped pipe, with its main connecting pipe connected to the flow pipe at the inlet. Two branch connecting pipes connect to the hydrogen inhalation machine and the hot water system respectively, allowing hydrogen and hot water to be alternately input into the flow pipe. This creates a pre-defined hot water section and a hydrogen section within the flow pipe. The hot water flow effectively controls the hydrogen release rate, achieving a slow-release effect. Furthermore, the hot water section increases the temperature of the affected area, improving comfort during treatment and enhancing hydrogen penetration and absorption efficiency.

[0035] Please see Figures 1 to 8The present invention provides a description of a hydrogen compress. A hydrogen compress includes a base film layer 10, a permeable layer 20, and a flow channel 30. The base film layer 10 is made of a waterproof and airtight material. The base film layer 10 has an inlet 11 and an outlet 12. The permeable layer 20 is made of a waterproof and breathable material, and its edges are sealed to the base film layer 10. The permeable layer 20 is applied to the affected area and permeates hydrogen gas towards the affected area. A receiving cavity 21 is formed between the base film layer 10 and the permeable layer 20, and the inlet 11 and outlet 12 are connected to the receiving cavity 21. The flow channel 30 is made of a waterproof and breathable material and is fixedly installed within the receiving cavity 21. The flow channel 30 is spirally arranged, with its two ends passing through the inlet 11 and outlet 12, respectively. Hydrogen gas enters the receiving cavity 21 from the flow channel 30 located in the inlet 11, and the hydrogen gas passes through the flow channel 30 and the permeable layer 20 to act on the affected area.

[0036] Compared with existing technologies, the hydrogen dressing provided by this utility model mainly consists of a base film layer 10, a permeable layer 20, and a flow channel 30. The base film layer 10 is made of a waterproof and breathable material and has an inlet 11 and an outlet 12. This characteristic effectively prevents moisture and gas from flowing out while providing a channel for hydrogen to enter and exit. The permeable layer 20 is made of a waterproof and breathable material, and its edges are sealed to the base film layer 10, thus forming a receiving cavity 21 between the base film layer 10 and the permeable layer 20. The inlet 11 and the outlet 12 are connected to the receiving cavity 21. The permeable layer 20 is applied to the affected area and can permeate hydrogen towards the affected area. Its waterproof and breathable characteristics ensure that hydrogen can smoothly penetrate to the affected area while preventing external moisture and contaminants from entering the receiving cavity 21, maintaining a stable environment within the receiving cavity 21. The flow channel 30, also made of waterproof and breathable material, is fixedly installed within the receiving cavity 21 and arranged in a spiral pattern, with its two ends passing through the inlet 11 and outlet 12, respectively. In use, the permeable layer 20 of the hydrogen patch is first applied to the affected area, ensuring a tight seal. Then, hydrogen gas enters the flow channel 30 through the inlet 11. Because the flow channel 30 is spirally arranged within the receiving cavity 21, the flow path and residence time of the hydrogen gas within the cavity are increased. During the flow, the hydrogen gas gradually diffuses into the receiving cavity 21 through the waterproof and breathable material of the flow channel 30, then passes through the permeable layer 20 to act on the affected area, or the hydrogen gas directly passes through the permeable layer 20 from within the flow channel 30 to act on the affected area. The remaining hydrogen gas is discharged from the outlet 12, completing one treatment cycle. In this way, the spiral arrangement of the flow channel 30 prolongs the residence time of hydrogen in the receiving cavity 21, enabling a continuous and stable release of hydrogen. By controlling the input parameters of hydrogen, the release rate of hydrogen can be flexibly adjusted, achieving the goal of controlling the release of hydrogen molecules according to user needs. Furthermore, the waterproof and airtight properties of the base membrane layer 10 and the sealed connection between the permeable layer 20 and the base membrane layer 10 effectively reduce hydrogen leakage, ensuring the concentration of hydrogen in the receiving cavity 21, thereby improving the therapeutic effect of hydrogen.

[0037] Please see Figures 1 to 5As a specific embodiment of the hydrogen plaster provided by this utility model, the permeation layer 20 and the flow channel 30 are integrally molded. The flow channel 30 protrudes outward from the side of the permeation layer 20 toward the base membrane layer 10, achieving deep integration of the two in terms of material and structure. The flow channel 30 exists directly as an extension structure of the permeation layer 20 without additional assembly, naturally forming a swirling gas channel within the receiving cavity 21. On the one hand, the integral molding process eliminates the connection gap between the permeation layer 20 and the flow channel 30 in traditional assembly, eliminating the risk of hydrogen leakage from the structural source. Combined with the sealing design of the base membrane layer 10, it significantly improves the airtightness of the receiving cavity 21. On the other hand, the protruding structure of the flow channel 30 forms a three-dimensional flow guiding space within the receiving cavity 21, ensuring the orderly flow of hydrogen within the channel and optimizing the diffusion efficiency of hydrogen from the channel to the permeation layer 20 through material consistency with the permeation layer 20, allowing hydrogen to act more directly and stably on the affected area.

[0038] Please see Figure 1 , Figure 4 and Figure 5 In one specific embodiment of the hydrogen application provided by this utility model, the side of the flow channel 30 away from the permeation layer 20 is connected to the base membrane layer 10. That is, the side of the channel facing the base membrane layer 10 is connected to the base membrane layer 10 by means of abutment, adhesion, or other methods. Combined with its spiral arrangement, it can form a stable spatial structure within the receiving cavity 21. Using this method, by connecting and fixing it to the base membrane layer 10, displacement and entanglement of the flow channel 30 are prevented during hydrogen delivery or application, ensuring a stable hydrogen flow path and a uniform release rate; it also improves the overall structural stability and prevents the channel from falling off due to external pulling.

[0039] Please see Figures 1 to 6 As a specific embodiment of the hydrogen patch provided by this utility model, the two ends of the flow pipe 30 are respectively provided with connecting pipe sections 31 extending out of the receiving cavity 21, and the outer surface of the connecting pipe section 31 is provided with a sealing layer 32. The connecting pipe section 31 provides access to an external hydrogen source, water source, or discharge device. The sealing layer 32 on its outer surface is made of a highly sealing material to prevent hydrogen or other substances from leaking from the connecting pipe section 31. Silicone or hot melt adhesive is applied to the connecting pipe section 31 to seal the gap between the connecting pipe section 31 and the inlet 11 and outlet 12. The sealing layer 32 is made of a waterproof and airtight material. The sealing layer 32 enables the connecting pipe section 31 to have waterproof and airtight properties, enhancing the sealing characteristics of the hydrogen patch during use and ensuring a stable hydrogen concentration in the receiving cavity 21; the extended connecting pipe section 31 facilitates quick insertion and removal of external pipelines, improving operational convenience.

[0040] In one specific embodiment of the hydrogen dressing provided by this utility model, multiple flow channels 30 are arranged side-by-side at intervals within the receiving cavity 21. The two ends of each channel are connected to the inlet 11 and the outlet 12, respectively, forming a multi-channel parallel hydrogen delivery structure. The multiple channels increase the contact area between hydrogen and the permeation layer 20, making the hydrogen distribution on the permeation layer 20 more uniform and avoiding the problem of uneven local release concentration found with a single channel. The interval arrangement allows for more complete diffusion of hydrogen within the receiving cavity 21, increasing the hydrogen coverage area applied to the affected area.

[0041] As a specific embodiment of the hydrogen plaster provided by this utility model, the base film layer 10 is made of aluminum film. Utilizing the natural waterproof and airtight properties of aluminum film, it meets the functional requirements of the base film layer 10 to block external substances and retain internal hydrogen. Its surface can be tightly sealed to the edge of the permeation layer 20 through hot melting or adhesive bonding processes, forming a stable receiving cavity 21. The high sealing performance of aluminum film far exceeds that of ordinary plastic film, which can minimize the leakage of hydrogen from the base film layer 10 itself or the sealing edge, ensuring the hydrogen concentration in the receiving cavity 21. The aluminum film has a certain rigidity, which can support the structure of the receiving cavity 21 and prevent the flow channel 30 from deforming and becoming blocked due to external pressure. At the same time, the aluminum film is resistant to chemical corrosion and aging.

[0042] As a specific embodiment of the hydrogen dressing provided by this utility model, both the permeation layer 20 and the flow channel 30 are made of polytetrafluoroethylene (PTFE). PTFE has excellent waterproof and breathable properties, which not only meet the requirements of the permeation layer 20 to permeate hydrogen gas into the affected area while blocking external moisture, but also allow the hydrogen gas in the flow channel 30 to smoothly pass through the tube wall into the receiving cavity 21. Its chemical stability is extremely strong; it will not react with hydrogen gas upon contact, thus maintaining the purity of the hydrogen gas. PTFE has good biocompatibility, does not irritate the skin upon contact, and is suitable for long-term application.

[0043] Please see Figure 1 and Figure 2 As a specific embodiment of the hydrogen compress provided by this utility model, the hydrogen compress further includes a sealing ring layer 22 located on the side of the permeation layer 20 away from the base film layer 10; the sealing ring layer 22 is arranged along the edge of the permeation layer 20; the sealing ring layer 22 is provided on the side of the permeation layer 20 away from the base film layer 10, and the sealing ring layer 22 is arranged along the edge of the permeation layer 20, usually made of elastic materials such as silicone, so as to fit tightly to the skin. With the close contact between the sealing ring layer 22 and the skin, an additional sealing barrier is formed at the edge of the permeation layer 20, further preventing hydrogen gas from leaking from the gap between the permeation layer 20 and the skin, and enhancing the directional permeation efficiency of hydrogen gas to the affected area; at the same time, it can block external sweat, moisture, etc. from entering from the edge, avoiding contamination of the permeation layer 20 or affecting its breathability; the elastic material can adapt to skin movement, improve the stability of the compress to the skin, and reduce treatment interruption caused by displacement.

[0044] Please see Figure 1 and Figure 4 As a specific embodiment of the hydrogen patch provided by this utility model, the hydrogen patch also includes a breathing hole 13 penetrating the base film layer 10 and the permeable layer 20. The user's nostrils correspond to the breathing hole 13, or the nose passes through the breathing hole 13 and is located outside the hydrogen patch, facilitating stable breathing. A sealing gasket is provided on the permeable layer 20 around the breathing hole 13 to achieve a sealing effect. The inner wall of the breathing hole 13 is a connecting ring that is sealed and connected to the base film layer 10 and the permeable layer 20. This connecting ring is made of a waterproof and airtight material.

[0045] Please see Figure 1 , Figure 4 and Figure 7 As a specific embodiment of the hydrogen patch provided by this utility model, the flow pipe 30 is provided with multiple hot water sections 34 and multiple hydrogen sections 33, and the multiple hydrogen sections 33 are respectively arranged between two adjacent hot water sections 34. That is, the flow pipe 30 has alternating hot water sections 34 and hydrogen sections 33, and the hydrogen sections 33 are respectively located between adjacent hot water sections 34. The hot water sections 34 can regulate the ambient temperature of the adjacent hydrogen sections 33 through heat, and improve the user's comfort during the application process by using a suitable water temperature. By means of the alternating arrangement of hot water sections 34 and hydrogen sections 33, the slow release control of hydrogen gas is achieved, and the effective action time is extended; the heat of the hot water sections 34 with a certain temperature can promote blood circulation in the affected area and enhance the efficiency of hydrogen gas penetration and absorption.

[0046] Please see Figure 7 and Figure 8 This utility model embodiment also provides a hydrogen plastering device, which includes any of the above-mentioned hydrogen plasters, and further includes a hydrogen absorption machine 40, a hot water system 41, a feed pipe 42, and a return water pipe 45. The feed pipe 42 includes a main connecting pipe 43 and two branch connecting pipes 44. One end of the two branch connecting pipes 44 is connected to one end of the main connecting pipe 43, and the other end of the main connecting pipe 43 is connected to the end of the flow pipe 30 located in the inlet 11. The other ends of the two branch connecting pipes 44 are respectively connected to the hydrogen absorption machine 40 and the hot water system 41. One end of the return water pipe 45 is connected to the other end of the flow pipe 30.

[0047] The hydrogen therapy device provided by this utility model uses the aforementioned hydrogen patch. Therefore, by organically combining the hydrogen patch with the hydrogen inhalation machine 40, the hot water system 41, the delivery pipe 42, and the return water pipe 45, a complete hydrogen therapy system is constructed. The hydrogen inhalation machine 40 serves as the core hydrogen supply source, generating high-purity hydrogen. The hot water system 41 provides constant-temperature hot water. Both work collaboratively through the delivery pipe 42, and finally, the hydrogen and hot water are discharged and collected from the return water pipe 45. The delivery pipe 42 is a Y-shaped pipe, with its main connecting pipe 43 connected to the flow pipe 30 at the inlet 11. Two branch connecting pipes 44 connect to the hydrogen inhalation machine 40 and the hot water system 41 respectively, allowing hydrogen and hot water to be alternately input into the flow pipe 30. This creates a pre-defined hot water section 34 and a hydrogen section 33 within the flow pipe 30. The release rate of hydrogen can be effectively controlled through the flow of hot water, achieving a slow-release effect. Furthermore, the hot water section 34 enhances the temperature of the affected area, improving both comfort during treatment and hydrogen permeation and absorption efficiency. The water temperature in the hot water section is set to 38-40℃. The hydrogen compress device also includes a reversing valve, with the main connecting pipe 43 and two branch connecting pipes 44 all connected to the reversing valve, thus allowing for a stable and accurate alternating input of hydrogen and hot water from the two branch connecting pipes 44 into the main connecting pipe 43.

[0048] This hydrogen application device with its structure enables controllable hydrogen supply and release. The hydrogen inhalation machine 40 can provide a stable flow of hydrogen as needed, while the hot water system 41 precisely controls the slow release rhythm of hydrogen through temperature regulation. This solves the problem that traditional hydrogen-containing patches cannot autonomously adjust the release rate, meeting the needs of different diseases for hydrogen concentration and duration of action. The introduction of the hot water system 41 can promote blood circulation in the affected area through the thermal effect, enhance the skin's ability to absorb hydrogen, and synergistically improve anti-inflammatory and repair effects. The design of the branch connecting pipe 44 of the delivery pipe 42 realizes the modular integration of the gas source and heat source, ensuring independent delivery paths for hydrogen and hot water, while achieving efficient convergence through the main connecting pipe 43. This avoids operational inconvenience caused by complex pipelines and improves the ease of use of the equipment.

[0049] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
