[0044] Embodiment One

[0045] In an alternative embodiment, referring to Figures 1-7 The present embodiment provides a traditional Chinese medicine patch, which comprises a skin-friendly layer 10, a protective layer 30 covering the skin-friendly layer 10 and being pasted on the top of the skin-friendly layer 10, and a medicine storage layer 20 detachably connected between the skin-friendly layer 10 and the protective layer 30, wherein the medicine storage layer 20 is replaceable. The traditional Chinese medicine patch further comprises a tearable component, which comprises a first tearable part 41, a second tearable part 42 and a third tearable part 43. The skin-friendly layer 10 is fixed with the first tearable part 41, which is detachably fixed on the top of the skin-friendly layer 10 in a folded state. The medicine storage layer 20 is fixed with the second tearable part 42, which is detachably fixed on the top of the medicine storage layer 20 in a folded state. The protective layer 30 is fixed with the third tearable part 43, which is detachably fixed on the top of the protective layer 30 in a folded state.

[0046] The skin-friendly layer 10 comprises a first body 11, a first adhesive layer 12 and a limiting groove 15. The limiting groove 15 is formed on the top surface of the first body 11. The top surface of the first body 11 is divided into a first limiting mark area 13 and a second limiting mark area 14. The first adhesive layer 12 is fixed on the bottom surface of the first body 11 and is in contact with the skin of a patient. In order to protect and prevent pollution, the bottom surface of the skin-friendly layer 10 is covered with a first protective film 16, and the top surface of the skin-friendly layer 10 is covered with a second protective film 17. That is, the first adhesive layer 12 is covered with the first protective film 16, and the top surface of the first body 11 is covered with the second protective film 17.

[0047] The medicine storage layer 20 comprises a second body 21, a medicine ointment 24 and a second adhesive layer 25. The bottom surface of the second body 21 is divided into a medicine storage area 23 and a sticking area 22. The medicine storage area 23 is coated with the medicine ointment 24, which can be placed in the limiting groove 15. The second adhesive layer 25 is fixed on the sticking area. In order to protect and prevent pollution, the bottom surface of the medicine storage layer 20 is covered with a third protective film 26, and the top surface of the medicine storage layer 20 is covered with a fourth protective film 27. That is, the second adhesive layer 25 and the medicine ointment 24 are covered with the third protective film 26, and the top surface of the second body 21 is covered with the fourth protective film 27.

[0048] The protective layer 30 comprises a third body 31 and a third adhesive layer 34, and the bottom surface of the third body 31 is divided into a third limiting mark area 32 and a fourth limiting mark area 33. The third limiting mark area 32 is fixed with the third adhesive layer 34, and the fourth limiting mark area 33 is fixed with a fourth adhesive layer 35. In order to prevent pollution, the bottom surface of the protective layer 30 is covered with a fifth protective film 36, and the fourth adhesive layer 35 and the fifth adhesive layer are covered with the fifth protective film 36.

[0049] It can be understood that for the skin-friendly layer 10, the first adhesive layer 12 is a key part that enables the patch to firmly adhere to the diseased part of the patient, ensuring that the patch will not easily fall off during use and providing a stable basis for the drug to work. The limiting groove 15 is mainly used to place the ointment 24 of the drug storage layer 20, and to position the ointment 24 to prevent displacement of the ointment 24 during use, prevent the ointment 24 from polluting the patient's clothes or bedding, and ensure that the drug can accurately act on the diseased part, thereby improving the therapeutic effect of the drug. The first limiting mark area 13 and the second limiting mark area 14 are marks for precise adhesion with the drug storage layer 20 and the protective layer 30. When installing the drug storage layer 20 and the protective layer 30, by aligning these mark areas, the correct connection between the layers can be ensured, making the structure of the patch more stable, and also helping to maintain the positional accuracy of the drug. When the patch is not in use, the first protective film 16 covers the first adhesive layer 12, which can prevent the adhesive layer from being contaminated or losing its adhesion. The second protective film 17 covers the top surface of the first body 11, which plays a protective role to avoid damage to the skin-friendly layer 10 and the limiting groove 15 by external factors such as dust and moisture during storage and transportation, thereby ensuring the quality and performance of the patch.

[0050] For the skin-friendly layer 10, the surface of the limiting groove 15 can be treated with a microstructure, such as making some small protrusions or grooves, to increase the contact area between the drug and the surface of the limiting groove 15, so that the drug can be better distributed in the limiting groove 15 during release, and also facilitate uniform drug release. For example, micron-level protrusions can be made on the surface of the bottom of the limiting groove 15 by laser etching and other techniques. These protrusions can make the drug molecules change direction during diffusion, increasing the chances of drug contact with the skin. In order to control the release effect of the drug, the depth and shape of the limiting groove 15 can also be adjusted appropriately. For example, the edges of the limiting groove 15 can be designed as curved or inclined, which can make the drug more easily accumulate on the skin surface during diffusion; for some drugs that need to act quickly, the depth of the limiting groove 15 can be designed to be slightly shallower, so that the distance between the drug and the skin is closer, and the path of the drug molecules diffusing to the skin surface is shorter, facilitating the rapid release of the drug. For sustained-release drugs, the depth can be appropriately increased.

[0051] It should be noted that in order to prevent the first body 11 from being too thick and affecting use, the limiting groove 15 can also be designed as a limiting ring fixed on the first body 11.

[0052] For the drug storage layer 20, the drug storage area 23 is a specific area for storing the medicinal paste 24, which is the core part for exerting therapeutic effect. By concentrating the medicinal paste 24 in the drug storage area 23, the amount and distribution of the drug can be ensured to be relatively uniform, which is conducive to the stable release of the drug. The second adhesive layer 25 is located in the adhesion area 22, and firmly connects the drug storage layer 20 and the skin-friendly layer 10 together. When the drug storage layer 20 is installed on the skin-friendly layer 10, the second adhesive layer 25 is attached to the first limiting mark area 13 of the skin-friendly layer 10, ensuring the accurate position of the drug storage layer 20 and preventing it from being easily displaced during use, thereby ensuring good contact between the drug and the diseased part. The third protective film 26 covers the second adhesive layer 25 and the medicinal paste 24, which can prevent the medicinal paste 24 from being contaminated or the adhesion from being affected when not in use. The fourth protective film 27 covers the top surface of the second body 21, which also serves to protect the drug storage layer 20, preventing it from being damaged during storage and transportation, and ensuring that the quality and performance of the drug are not affected by external factors.

[0053] For the protective layer 30, air permeable holes are added to the third body 31 or the third body 31 is made of a material with better air permeability, such as micro-porous polyurethane. The good air permeability of the protective layer 30 can maintain the air circulation inside the patch, preventing problems such as changes in drug concentration or drug adhesion caused by water vapor accumulation inside the patch. By maintaining a stable internal environment of the patch, the process of drug release from the drug storage layer 20 to the skin is more stable and efficient, improving the drug release effect. The third adhesive layer 34 is located in the third limiting mark area 32, which is mainly used to tightly attach the protective layer 30 to the drug storage layer 20. During use, the protective layer 30 can protect the drug storage layer 20 from damage from external factors such as impact and friction. By aligning the third limiting mark area 32 for attachment, the connection between the protective layer 30 and the drug storage layer 20 can be ensured to be tight and accurate in position. The fourth adhesive layer 35 is located in the fourth limiting mark area 33, which enhances the stability of the connection between the protective layer 30 and the skin-friendly layer 10 when the protective layer 30 is attached to the skin-friendly layer 10. The design of multiple layers of adhesion can make the entire patch structure more firm, preventing the patch from delaminating during use. The fifth protective film 36 covers the fourth adhesive layer 35 and the fifth adhesive layer on the bottom surface of the protective layer 30, which prevents the third adhesive layer 34 and the fourth adhesive layer 35 from being contaminated or losing adhesion when not in use, and also protects the bottom surface structure of the protective layer 30 from being damaged during storage and transportation.

[0054] The design of the easy-tear component is mainly to facilitate the user to peel off each layer. When it is necessary to replace the medicine storage layer 20 or to peel off each layer after use, the easy-tear part is unfolded to easily find the starting position of peeling off, thereby avoiding the problem that it is difficult to peel off each layer due to the lack of a suitable force point. For example, when replacing the medicine storage layer 20, the user can start to peel off the protective layer 30 from the third easy-tear part 43 and start to peel off the medicine storage layer 20 from the second easy-tear part 42, which is more convenient to operate.

[0055] It should be noted that each adhesive layer can be made of medical pressure-sensitive adhesive with air holes, which can ensure firm adhesion between layers and allow the skin to breathe normally. Good air permeability helps to maintain the stability of the microenvironment on the skin surface, reduces skin discomfort caused by factors such as heat and humidity, and indirectly improves the release effect of the medicine.

[0056] In use, the first protective film 16 and the second protective film 17 of the skin-friendly layer 10 are removed, and the first adhesive layer 12 of the skin-friendly layer 10 is attached to the diseased part of the patient; the third protective film 26 of the medicine storage layer 20 is removed, aligned with the position of the limiting groove 15, and the ointment 24 is attached to the bottom of the limiting groove 15, i.e., the first body 11 of the skin-friendly layer 10, and the second adhesive layer 25 is attached to the first limiting mark area 13; the fourth protective film 27 of the medicine storage layer 20 is removed, the fifth protective film 36 of the protective layer 30 is removed, and the position is aligned, so that the third adhesive layer 34 is attached to the top surface of the medicine storage layer 20, and the fourth adhesive layer 35 is attached to the second limiting mark area 14 of the first body 11, thereby completing the use of the traditional Chinese medicine patch.

[0057] When it is necessary to replace the medicine storage layer 20, the third easy-tear part 43 in the folded state is unfolded, and the protective layer 30 is peeled off from the third easy-tear part 43; the second easy-tear part 42 in the folded state is unfolded, and the medicine storage layer 20 is peeled off from the second easy-tear part 42, and the old medicine storage layer 20 is removed; then the third protective film 26 of the new medicine storage layer 20 is removed, the ointment 24 is attached to the bottom of the limiting groove 15, i.e., the first body 11 of the skin-friendly layer 10, and the second adhesive layer 25 is attached to the first limiting mark area 13; the fourth protective film 27 of the new medicine storage layer 20 is removed, the protective layer 30 and the new medicine storage layer 20 are aligned, the third adhesive layer 34 is attached to the top surface of the new medicine storage layer 20, and the fourth adhesive layer 35 is attached to the second limiting mark area 14 of the first body 11, thereby completing the use of the traditional Chinese medicine patch.

[0058] When the traditional Chinese medicine patch is used up, the first easy-tear part 41 in the folded state is unfolded, and the skin-friendly layer 10 is peeled off from the third easy-tear part 43, thereby ending the use of the traditional Chinese medicine patch.

[0059] It should be noted that the fourth limiting mark area 33 on the bottom surface of the third body 31 coincides with the part of the second easy-to-tear portion 42 in the folded state, and there is no fifth adhesive layer, which does not affect the use of the second easy-to-tear portion 42.

[0060] The traditional Chinese medicine patch of the embodiment has the following advantages in the synergistic action of the skin-friendly layer 10, the drug storage layer 20, the protective layer 30, and the easy-to-tear assembly:

[0061] Enhanced stability: The first adhesive layer 12 of the skin-friendly layer 10 fixes the patch on the patient's skin, providing basic stability for the entire patch structure. The drug storage layer 20 is tightly connected to the skin-friendly layer 10 through the second adhesive layer 25, and the protective layer 30 is attached to the drug storage layer 20 and the skin-friendly layer 10 through the third adhesive layer 34 and the fourth adhesive layer 35, respectively, forming a multi-layer stable structure. This structure can effectively prevent the patch from shifting or falling off during the patient's daily activities, ensuring that the drug is always in the correct position. For example, when the patient walks or exercises, the layers can resist external interference and ensure the stability of drug release.

[0062] Drug protection and precise release: As the outermost layer, the protective layer 30 can effectively prevent external factors such as dust and moisture from contaminating and damaging the drug storage layer 20. The drug storage layer 20 is sandwiched between the skin-friendly layer 10 and the protective layer 30, and the drugs inside are well protected in this relatively closed environment. At the same time, the limiting groove 15 of the skin-friendly layer 10 can precisely position the drugs of the drug storage layer 20, so that the drugs can accurately act on the diseased area. For example, for the treatment of local pain or inflammation, the drugs can be precisely released to the central area of the pain or inflammation, improving the therapeutic effect of the drugs.

[0063] Improved skin adaptability and comfort: The skin-friendly layer 10 directly contacts the skin, and the designed first adhesive layer 12 has good skin-friendliness, which can reduce the occurrence of skin allergies and other adverse reactions. The breathable performance and appropriate flexibility of the protective layer 30 can avoid excessive pressure or friction on the skin. When the three layers are used together, they can provide a comfortable patch experience for the patient, making the patient more willing to use the patch for a long time, thereby ensuring that the drugs have enough time to release and play a role.

[0064] The advantages of the tearable component matched with each layer structure: the design of the first tearable part 41 of the skin-friendly layer 10, the second tearable part 42 of the drug storage layer 20, and the third tearable part 43 of the protective layer 30 makes it more convenient to apply and replace during use. When using for the first time, the user can easily peel off the protective film of each layer according to the guide of the tearable part to perform the application operation. When the drug storage layer 20 needs to be replaced, these tearable parts can help the user accurately peel off the protective layer 30 and the drug storage layer 20, avoiding damage to the application structure or causing the drug to scatter due to forced peeling. For example, in a hospital environment, medical staff can quickly and accurately replace the drug storage layer 20 for patients, improving work efficiency. The presence of the tearable part makes the peeling process of each layer more orderly, reducing the opportunity for fingers and other direct contact with the drug and the internal structure of the application, thereby reducing the risk of contamination. When peeling off the protective layer 30 and the drug storage layer 20, starting from the tearable part can avoid direct contact of external contaminants with the drug, ensuring the quality and safety of the drug and facilitating the normal release of the drug.

[0065] Embodiment Two

[0066] For convenience of use, the drug storage layer 20 and the protective layer 30 can be designed as an integrated structure.

[0067] Reference Figures 2-3 , Figures 8-9 The traditional Chinese medicine patch provided by the embodiment includes a skin-friendly layer 10, a protective layer 30 covering the skin-friendly layer 10 and being pasted on the top of the skin-friendly layer 10, a drug storage layer 20 fixed on the bottom surface of the protective layer 30, and a sixth protective film 37 fixed on the top surface of the protective layer 30. The skin-friendly layer 10 is fixed with a first tearable part 41, which is detachably fixed on the top of the skin-friendly layer 10 in a folded state. The protective layer 30 is fixed with a third tearable part 43, which is detachably fixed on the top of the protective layer 30 in a folded state.

[0068] The skin-friendly layer 10 includes a first body 11, a first adhesive layer 12, and a limiting groove 15. The limiting groove 15 is formed on the top surface of the first body 11, and a second limiting mark area 14 is divided on the top surface of the first body 11. The first adhesive layer 12 is fixed on the bottom surface of the first body 11 to be attached to the skin of a patient. In order to protect and prevent pollution, the bottom surface of the skin-friendly layer 10 is covered with a first protective film 16, and the top surface of the skin-friendly layer 10 is covered with a second protective film 17; that is, the first adhesive layer 12 is covered with the first protective film 16, and the top surface of the first body 11 is covered with the second protective film 17.

[0069] The medicine storage layer 20 comprises a second body 21, a medicine cream 24 and a second adhesive layer 25. The bottom surface of the second body 21 is divided into a medicine storage area 23 and an adhesive area 22. The medicine storage area 23 is coated with the medicine cream 24, which can be placed in the limiting groove 15. The adhesive area is fixed with the second adhesive layer 25. The protective layer 30 comprises a third body 31, and the bottom surface of the third body 31 is fixed with the top surface of the medicine storage layer 20. In order to prevent contamination, the bottom surface of the medicine storage layer 20 is covered with a third protective film 26, i.e. the second adhesive layer 25 and the medicine cream 24 are covered with the third protective film 26, and the top surface of the protective layer 30 is covered with a sixth protective film 37.

[0070] It can be understood that the skin-friendly layer 10 comprises a first body 11, a first adhesive layer 12, a limiting groove 15, a second limiting mark area 14 on the top surface, and an adhesive layer on the bottom surface for adhering to the skin. The upper and lower surfaces are respectively provided with a first protective film 16 and a second protective film 17. The first adhesive layer 12 ensures that the patch can be tightly and stably attached to the patient's skin, provides basic support for the entire patch structure, prevents the patch from falling off, and allows the medicine to continuously act on the affected area. The limiting groove 15 precisely positions the medicine cream 24 of the medicine storage layer 20, limits the position of the medicine, avoids the medicine from moving randomly in the patch, ensures that the medicine precisely acts on the area that needs to be treated, and improves the utilization efficiency of the medicine. The second limiting mark area 14 is used to accurately adhere to the protective layer 30, ensures the standardization of the connection between the protective layer 30 and the skin-friendly layer 10, and thus maintains the stability of the entire patch structure, and also helps to guide the accurate position of the medicine storage layer 20. The first protective film 16 and the second protective film 17 prevent the first adhesive layer 12 from being contaminated or the adhesion being reduced when not in use, and protect the body of the skin-friendly layer 10 from external damage, ensuring the quality of the patch during storage and transportation.

[0071] The medicine storage layer 20 comprises a second body 21, a medicine paste 24, and a second adhesive layer 25. The bottom surface of the second body 21 is divided into a medicine storage area 23 (where the medicine paste 24 is placed and corresponds to the limiting groove 15) and an adhesive area 22 (where the second adhesive layer 25 is fixed). The bottom surface of the medicine storage layer 20 is provided with a third protective film 26. The third body 31 of the protective layer 30 is fixed with the medicine storage layer 20 at the bottom surface, and the top surface is provided with a sixth protective film 37. The medicine storage area 23 is the core area for storing and releasing medicine. The medicine paste 24 carries the therapeutic effect. Reasonable division of the medicine storage area 23 can ensure uniform distribution and stable release of medicine. The second adhesive layer 25 is used to firmly combine the medicine storage layer 20 with the second limiting mark area 14 of the skin-friendly layer 10. The third protective film 26 prevents the medicine paste 24 from being contaminated, the adhesion changing, or the medicine ingredients being lost during the storage stage, thereby maintaining the effectiveness of the medicine paste 24 and ensuring that the medicine can normally play a role when used. The third body 31 serves as an outer protective structure to resist physical damage such as collision and friction from the outside for the medicine storage layer 20. At the same time, by being attached to the skin-friendly layer 10, the third body 31 helps to maintain the stability of the overall structure of the patch. The sixth protective film 37 protects the surface of the protective layer 30 when not in use, prevents it from being contaminated by dust, water vapor, and other impurities, ensures the cleanliness of the protective layer 30, and avoids pollution to the medicine storage layer 20 and the skin-friendly layer 10.

[0072] The first easy-tear part 41 facilitates the removal of the skin-friendly layer 10 after use, provides a force point for the user, and is convenient to operate, thereby avoiding forced tearing and causing discomfort to the skin. The third easy-tear part 43 facilitates the removal of the protective layer 30, whether it is the first use or the replacement of the medicine storage layer 20. The user can quickly find the starting position for removal, making the operation smoother and reducing the risk of damage to the internal structure of the patch.

[0073] The traditional Chinese medicine patch of the embodiment is composed of the skin-friendly layer 10 and the protective layer 30. The medicine storage layer 20 is fixed to the bottom surface of the protective layer 30, forming an integrated design. The skin-friendly layer 10 has the first easy-tear part 41, and the protective layer 30 has the third easy-tear part 43, each of which is covered with a protective film. Designing the medicine storage layer 20 and the protective layer 30 as a whole reduces the number of components and simplifies the operation steps when using and replacing the medicine storage layer 20. The user does not need to align and attach multiple layers of structure separately. Instead, the user only needs to remove the corresponding protective film, attach the skin-friendly layer 10 to the skin, and then handle the whole of the protective layer 30 and the medicine storage layer 20, thereby reducing the difficulty of use, especially for patients to change medicine at home. The integrated design makes the connection between the medicine storage layer 20 and the protective layer 30 more stable, avoids the relative displacement of multiple layers of structure that may occur in daily activities, ensures the stability of the position of the medicine in the patch, and is conducive to the continuous and precise action of the medicine on the diseased part, thereby improving the treatment effect. The protective layer 30 wraps the medicine storage layer 20 in all directions, in combination with the protective films of each layer, which can more effectively block external dust, water vapor, and other pollutants, protect the quality of the medicine paste 24, ensure the normal release of the medicine, and reduce the risk of medicine failure caused by pollution.

[0074] In use, the first protective film 16 covering the bottom surface of the skin-friendly layer 10 is removed to expose the first adhesive layer 12, and the second protective film 17 on the top surface of the skin-friendly layer 10 is also removed; the first adhesive layer 12 of the skin-friendly layer 10 is aligned with the diseased part of the patient, and is flatly attached to the skin to ensure that the position of the limiting groove 15 is correct. The sixth protective film 37 on the top surface of the protective layer 30 is removed, and at this time, the third protective film 26 of the medicine storage layer 20 still covers the bottom surface of the medicine storage layer 20 (i.e. the second adhesive layer 25 and the ointment 24); the third protective film 26 covering the second adhesive layer 25 and the ointment 24 is removed, the protective layer 30 (with the medicine storage layer 20 fixed to the bottom surface thereof) is aligned with the skin-friendly layer 10, the ointment 24 of the medicine storage layer 20 is aligned with the limiting groove 15 of the skin-friendly layer 10, and the second adhesive layer 25 is correctly attached to the second limiting mark area 14 of the skin-friendly layer 10, and the initial use of the patch is completed. In this process, the medicine storage layer 20 is squeezed during the attachment process, so that the ointment 24 can be better attached to the limiting groove 15.

[0075] When the ointment 24 is replaced, the third tearable part 43 of the protective layer 30 is unfolded, the protective layer 30 is removed from the third tearable part 43, and the protective layer 30 (with the old medicine storage layer 20) is removed from the skin-friendly layer 10. A new protective layer 30 (with a medicine storage layer 20) is taken, the sixth protective film 37 on the top surface of the protective layer 30 is removed, the third protective film 26 covering the second adhesive layer 25 and the ointment 24 is removed, the protective layer 30 with the new medicine storage layer 20 is aligned with the skin-friendly layer 10 again, and the protective layer 30 is attached to the second limiting mark area 14 of the skin-friendly layer 10 again, and the replacement is completed.

[0076] When the patch is used up, the first tearable part 41 of the skin-friendly layer 10 is unfolded, the skin-friendly layer 10 is removed from the first tearable part 41, and the traditional Chinese medicine patch is removed from the skin, and the use is ended.

[0077] The traditional Chinese medicine patch improves the convenience of use. The design of the first tearable part 41 of the skin-friendly layer 10, the second tearable part 42 of the medicine storage layer 20 and the third tearable part 43 of the protective layer 30 makes the patch more convenient to use and replace.

[0078] The patch is suitable for various traditional Chinese medicine ointments 24, the position of the medicine is accurate, and the treatment effect of the medicine is enhanced. The ointment 24 of the medicine storage layer 20 can be in a paste shape or a cake shape, and the limiting groove 15 is mainly used for placing the ointment 24 of the medicine storage layer 20. The ointment 24 is positioned to prevent displacement of the ointment 24 during use, prevent the ointment 24 from polluting the clothes or bedding of the patient, and ensure that the medicine can accurately act on the diseased part, thereby improving the treatment effect of the medicine.

[0079] The protective layer 30 and the protective films can prevent the medicine from being polluted, prolong the shelf life and stability of the medicine.
