[0039] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0040] Example 1: An intradermal needle, comprising an adhesive layer 1, a drug layer 2, and a needle body 3;

[0041] like Figure 1 As shown, the adhesive layer 1 is set to a circular structure. In addition to the circular structure, it can also be designed into different appearances as needed, which plays the role of enriching the styles of intradermal needles;

[0042] Most importantly, the adhesive layer 1 serves as the adhesive fixing structure of the entire intradermal needle, which can fix the intradermal needle on the acupuncture point on the skin surface for a long time, achieving the purpose of long-term stimulation of the acupuncture point to treat the disease. The intradermal needle is most suitable for the treatment of insomnia.

[0043] The adhesive layer 1 is made of a waterproof membrane material, and the lower surface of the adhesive layer 1 is coated with a medical adhesive material that can directly contact the skin; a drug layer 2 is connected and fixed in the center of the lower surface of the adhesive layer 1, and the area of ​​the adhesive layer 1 is much larger than that of the drug layer 2; drugs for treating corresponding diseases are absorbed in the drug layer 2; for example, the Chinese medicine Acorus calamus can be placed in the drug layer 2 to treat insomnia; a needle body 3 is arranged on the drug layer 2, and the needle body 3 is a structure used to puncture into acupuncture points and stimulate the acupuncture points for treatment.

[0044] When in use, find the acupuncture point, align the needle tip of the needle body 3 with the acupuncture point, and then insert the needle into the acupuncture point percutaneously; after adjusting the intradermal needle to be flat and stable, ensure that the drug layer 2 also contacts the skin around the puncture point; then press the adhesive layer 1 to make the adhesive layer 1 adhere to the skin surface, and cover the drug layer 2 and the needle body 3 completely under the adhesive layer 1; since the adhesive layer 1 is made of waterproof film material, it can prevent the adhesive material below and the needle body from being stained with water, thereby causing the adhesive material to fail; and prevent the entire intradermal needle from falling off due to the failure of the adhesive material.

[0045] Because intradermal needles require continuous wear and stimulation of acupoints for a period of time to have a therapeutic effect, if the adhesive layer 1 is not waterproof, it will become ineffective after being soaked in water during bathing or swimming, requiring frequent replacement of the intradermal needles. This wastes the intradermal needles, while frequent percutaneous acupuncture can lead to redness, swelling, and inflammation at the puncture points. The adhesive layer in this embodiment has a good waterproof effect, which can extend the service life of the intradermal needle. In combination with the drug penetration effect of the drug layer 2, the therapeutic effect is enhanced.

[0046] Example 2: Based on Example 1, an intradermal needle includes: an adhesive layer 1, a drug layer 2, and a needle body 3;

[0047] In this embodiment, the adhesive layer 1 is also set to be circular. The adhesive layer 1 in Example 1 is waterproof because the adhesive layer 1 itself is made of a waterproof membrane material, and the adhesive material is directly coated under the waterproof membrane; the entire waterproof membrane is the adhesive body; although the waterproof membrane can also fit the skin surface, the waterproof membrane material is easy to break. When the intradermal needle is worn for a long time, the adhesive layer 1 made of the waterproof membrane material can be easily scratched by sharp objects. Once the adhesive layer 1 is scratched, water seepage will occur. After the adhesive material is soaked in water, the adhesive effect disappears, and the entire intradermal needle needs to be replaced.

[0048] like Figure 4 As shown, the adhesive layer 1 in this embodiment includes: an adhesive layer 101 and a waterproof coating 102;

[0049] The adhesive layer 101 is mainly made of medical tape or non-woven fabric. In short, the selected material is soft and can fit the skin surface; on the other hand, it is not easy to be damaged.

[0050] The lower surface of the adhesive layer 101 is coated with a medical adhesive material to serve the purpose of adhering and fixing the adhesive to the skin surface; the upper surface of the adhesive layer 101 is covered with a waterproof film 102, and the waterproof effect of the entire adhesive layer 1 is achieved by the waterproof film 102.

[0051] The drug layer 2 is centrally arranged on the lower surface of the adhesive layer 101. The area of ​​the adhesive layer 101 is much larger than that of the drug layer 2. The needle is then connected to the drug layer 2.

[0052] When in use, find the acupuncture point, align the needle tip 303 of the needle body 3 with the acupuncture point, and insert the needle body 3 into the acupuncture point; the drug layer 2 contacts the skin around the acupuncture point; press the adhesive layer 1, and use the adhesive layer 101 on the adhesive layer 1 to adhere to the skin surface to fix the intradermal needle; the waterproof coating 102 above the adhesive layer 1 ensures that water will not seep into the adhesive layer 101 and the drug layer 2.

[0053] Example 3: Based on Example 2, the drug layer 2 needs to be able to better adhere to the skin surface around the acupuncture points; therefore, the material of the drug layer 2 needs to be softer and more comfortable;

[0054] In this embodiment, the drug layer 2 is set to be a solid gel layer; the drug is doped in the gel layer. The application scenario of setting the intradermal needle in this embodiment is to treat insomnia, so the drug doped in the drug layer 2 can be the traditional Chinese medicine Acorus calamus, and the Acorus calamus can be made into a paste and applied to the side of the drug layer that contacts the skin; the center of the solid gel layer can also be set to be hollow, and liquid Acorus calamus medicine is perfused into the hollow structure of the solid gel layer, and a number of very fine drug infiltration holes are opened on the surface of the solid gel layer that contacts the skin, so that the drug flows from the drug infiltration holes to the skin surface and penetrates through the skin such as acupuncture points, thereby achieving the effect of acupuncture stimulation combined with drug treatment; this can enhance the treatment effect, shorten the treatment cycle, and reduce the time patients wear intradermal needles.

[0055] When the solid gel layer constitutes the drug layer 2, the upper surface of the solid gel layer is connected to the adhesive layer; and the needle body is further connected to the solid gel layer.

[0056] Example 4: Based on Example 2, the drug layer needs to be able to store drugs so that the drugs can contact the skin surface and penetrate slowly through the skin; the drug layer 2 in this example includes: a backing film and drug cotton;

[0057] The upper surface of the back film is connected to the adhesive layer 1, and the lower surface of the back film is evenly distributed with drug cotton; Acorus calamus drug powder is evenly sprinkled on the drug cotton or Acorus calamus drug is made into liquid medicine and the liquid medicine is soaked in the drug cotton.

[0058] The needle body 3 is arranged on the lower surface of the back film of the drug layer 2 .

[0059] When in use, find the acupuncture point, align the needle tip of the needle body 3 with the acupuncture point, and after the needle body 3 is inserted into the acupuncture point, make the medicine cotton completely contact the skin around the acupuncture point; then use the adhesive layer 1 to fix the entire intradermal needle; the Acorus calamus medicine on the medicine cotton will be absorbed through the skin, thereby improving the treatment effect and shortening the treatment cycle.

[0060] Example 5: There are two types of intradermal needles: granular type and nail-lifting type. Based on Example 2, this example uses a nail-lifting type intradermal needle.

[0061] The needle body 3 includes: an annular needle handle 301, a vertical needle handle 302 and a needle tip 303;

[0062] The annular needle handle 301 is a circular ring structure with more than one circle. The upper end of the vertical needle handle 302 is integrally formed at one end of the annular needle handle 301, and the lower end of the vertical needle handle 302 is integrally formed with a connecting needle tip 303 structure.

[0063] like Figure 2As shown, after the entire intradermal needle is assembled and connected, the annular needle handle 301 is located between the adhesive layer 1 and the drug layer 2 , and the vertical needle handle 302 passes through the drug layer 2 so that the needle tip 303 is located below the drug layer 2 .

[0064] When the drug layer 2 is configured as a solid gel layer, the annular needle handle 301 is centrally disposed on the upper surface of the gel layer. After the vertical needle handle 302 passes through the gel layer, the needle tip 303 is partially located below the gel layer.

[0065] When the drug layer 2 is set as a structure of a backing film and drug cotton, the annular needle handle 301 is centrally set on the upper surface of the backing film. After the vertical needle handle 302 passes through the backing film, the needle tip 303 is partially located below the backing film; the drug cotton is evenly laid on the lower surface of the backing film.

[0066] The entire needle body 3 is similar to a thumbtack structure. When the intradermal needle is worn, the entire needle tip 303 and the portion of the vertical needle handle 302 connected to the needle tip 303 will penetrate into the acupuncture point below the epidermis, achieving the purpose of acupuncture stimulation of the acupuncture point.

[0067] Example 6: Based on Example 5, before the intradermal needle is inserted into the acupuncture point, the skin around the acupuncture point needs to be disinfected, and the intradermal needle, especially the needle body, needs to be disinfected and sterilized; this can prevent bacteria from entering the puncture point. Once bacteria enter, the puncture point will become red, swollen and inflamed, and severe infection will occur.

[0068] Therefore, in this embodiment, the entire needle body 3 or at least the outer surface of the vertical needle handle 302 and the needle tip 303 is coated with an antibacterial layer, and the above-mentioned antibacterial layer can be an anionic antibacterial layer; in this way, the intradermal needle is implanted under sterile operation; the antibacterial layer on the needle body 3 can continue to exert its antibacterial effect during the use of the intradermal needle, thereby avoiding bacterial invasion and infection.

[0069] Example 7: Based on Example 5, when the drug layer 2 is a gel layer structure, the annular needle handle 301 of the needle body 3 is arranged on the upper surface of the gel layer; when the drug layer 2 is a backing film combined with drug cotton structure, the annular needle handle 301 is arranged on the upper surface of the backing film;

[0070] In short, regardless of the drug layer's two structures, the annular needle handle 301 is always located on the upper surface of the drug layer 2, that is, the side of the drug layer 2 that does not contact the skin. Therefore, when the entire intradermal needle is worn, the annular needle handle 301 on the upper surface of the drug layer 2, because the drug layer's gel structure, backing film, and drug cotton structures are all soft, and when the adhesive layer 1 is pressed and fixed, the annular needle handle 301 on the upper surface of the drug layer 2 can penetrate the soft gel layer, backing film, and drug cotton, exerting pressure on the skin surface. Because intradermal needles are worn for long periods of time, the annular needle handle 301 may cause pressure sores on the skin.

[0071] So if Figure 5 As shown, in this embodiment, a circular buffer ring 201 is provided on the lower surface of the drug layer 2 at the position corresponding to the circular needle handle 301 on the upper surface, so that the orthographic projection of the circular needle handle 301 is exactly within the buffer ring 201. The buffer ring 201 is supported by soft and elastic latex or silicone.

[0072] The drug layer 2 of the solid gel layer structure has a buffer gasket 201 directly disposed on the lower surface of the gel layer, that is, the side of the gel layer that contacts the skin;

[0073] The back film is combined with the drug layer of the drug cotton structure, and the buffer gasket 201 is set on the lower surface of the back film, that is, the side of the back film that contacts the skin; and then the drug cotton is evenly distributed on the back film.

[0074] Because the buffer washer 201 is soft and elastic, after the intradermal needle is worn, the adhesive layer is pressed down to fix it, and the buffer washer 201 is squeezed and deformed, which does not affect the contact between the drug cotton on the lower surface or back of the gel layer and the skin, and the drug can penetrate normally; in addition, under the action of the buffer washer 201, the compressive force of the upper annular needle handle 301 can be reduced.

[0075] Example 8: Based on Example 2, after the acupuncture points are accurately located, the insertion position may still be offset during acupuncture if there is insufficient experience.

[0076] like Figure 3 As shown, the intradermal needle in this embodiment further includes a positioning patch 4; the positioning patch 4 is not connected to the adhesive layer 1, the drug layer 2 and the needle body 3; the positioning patch 4 is made of a hand-tearable material, such as paper material.

[0077] The positioning sticker 4 is used to locate the acupuncture points and assist the needle in accurately inserting the acupuncture points. A small hole is opened in the center of the positioning sticker 4; and positioning markings are set perpendicular to each other along the edge of the small hole on the surface of the positioning sticker 4.

[0078] After finding the acupuncture point, place the positioning patch 4 on the acupuncture point, with the small hole positioned at the center of the acupuncture point as much as possible. During acupuncture, align the needle tip 303 with the small hole and then insert the needle, so that the needle can be accurately inserted into the acupuncture point. After insertion, the positioning patch 4 can be torn off and removed. The drug layer 2 is further adjusted and attached, and then fixed with the adhesive layer 1.
