[0026] To make the purpose, technical solution, and advantages of the present invention more clear, the technical solution of the present invention will be described in detail below. Obviously, the embodiments described are only some of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0027] like Figure 1-Figure 3 As shown, the utility model provides a safe intradermal needle, comprising a plastic layer 1, a tape layer 2 and a needle body 3. The plastic layer 1 and the tape layer 2 are arranged in sequence from top to bottom, and the fixed end of the needle body 3 passes through the tape layer 2 and is connected to the plastic layer 1; a folding groove 11 is provided on the upper end surface of the plastic layer 1, and by folding the plastic layer 1 along the folding groove 11, the sticky surface of the tape layer 2 is driven to adhere to form a closed wrapping space, which can completely wrap the needle body 3.

[0028] Furthermore, the plastic layer 1 is tightly attached to the non-adhesive surface of the tape layer 2 , and the needle tip of the needle body 3 is exposed outside the adhesive surface of the tape layer 2 .

[0029] By placing a plastic layer 1 on the non-adhesive surface of the tape layer 2, the upper end surface of the plastic layer 1 is provided with a folding groove 11 that serves as a guide. By precisely folding the plastic layer 1 along the folding groove 11, medical personnel force the adhesive surfaces of the tape layer 2 to adhere to each other, forming a closed wrapping space. This wrapping space can completely and tightly wrap the needle body 3, ensuring that the needle body 3 is completely enclosed, avoiding the risk of exposing the needle body 3 tip and accidental contact. Furthermore, the plastic layer 1 has a certain strength and toughness, which can effectively prevent the needle body 3 from puncturing the plastic layer 1 during the wrapping process, further improving safety.

[0030] As an optional embodiment, the plastic layer 1, the tape layer 2 and the needle body 3 are concentrically arranged, so that medical staff can more easily align and fix the needle body 3 during operation, especially in the process of folding and wrapping, and can more accurately confirm the relative positions between the plastic layer 1, the tape layer 2 and the needle body 3.

[0031] As an optional embodiment, the diameter of the adhesive tape layer 2 is larger than the diameter of the plastic layer 1 .

[0032] The adhesive tape layer 2 has a larger adhesion area, making the needle body 3 more stable when attached to the patient's body surface and less likely to fall off. Moreover, during the folding and wrapping process, the larger outer edge of the adhesive tape layer 2 can be fully and tightly adhered, providing a more tightly enclosed wrapping space for the needle body 3 and reducing the contact of the needle body 3 with the external environment.

[0033] As an optional embodiment, there are multiple folding grooves 11 , which extend radially along the plastic layer 1 , and the length of the folding groove 11 is greater than the length of the needle body 3 exposed outside the adhesive tape layer 2 .

[0034] Furthermore, the folding groove 11 may be designed to not completely penetrate the plastic layer 1 along the thickness direction, so that the bottom layer of the plastic layer 1 remains continuous and complete.

[0035] The folding groove 11 can also be designed to completely penetrate the plastic layer 1 along the thickness direction, so as to divide the plastic layer 1 into a plurality of discontinuous fan-shaped structural blocks.

[0036] The multiple folding grooves 11 provide medical personnel with multiple folding options, thereby increasing the flexibility of use.

[0037] The length of the folding groove 11 is greater than the length of the needle body 3 exposed outside the tape layer 2, ensuring that during the folding process, the plastic layer 1 can cover the exposed part of the needle body 3, avoiding puncturing the tape layer 2 and improving safety in use.

[0038] As an optional embodiment, the number of the folding grooves 11 is four, and they are evenly arranged along the circumference of the plastic layer 1 .

[0039] The four folding grooves 11 are evenly spaced along the circumference of the plastic layer 1 to improve the uniformity during the folding process. Parameters such as the depth and width of the folding grooves 11 can be set according to the use requirements.

[0040] The four folding grooves 11 are not completely arranged through the plastic layer 1 in the thickness direction, so that the bottom layer of the plastic layer 1 remains continuous and complete.

[0041] The folding operation is performed along any two opposite folding grooves 11, so that the plastic layer 1 is precisely folded along a preset path to form a semicircular structure. At the same time, the outer edge parts of the tape layer 2 are folded against each other and tightly bonded during the folding process, forming a closed and stable wrapping space, which safely wraps the needle body.

[0042] As an optional embodiment, a circular arc protrusion 12 is provided in the middle of the upper end surface of the plastic layer 1 , and the fixed end of the needle body 3 extends into the circular arc protrusion 12 .

[0043] The arc-shaped protrusion 12 provides an intuitive visual identifier for medical staff, enabling them to quickly and accurately identify the safe side and the needle side of the intradermal needle, thereby reducing the possibility of misoperation and the risk of needlestick injuries.

[0044] As an optional embodiment, an annular groove 13 is provided on the outer edge of the arc-surface protrusion 12 , one end of the folding groove 11 is connected to the annular groove 13 , and the other end thereof passes through the plastic layer 1 .

[0045] The annular groove 13 serves as the folding starting point of the folding groove 11 . The folding operation can start from the annular groove 13 and proceed along the path of the folding groove 11 to achieve folding of the plastic layer 1 .

[0046] As an optional embodiment, the plastic layer 1 and the adhesive tape layer 2 have different colors.

[0047] The plastic layer 1 and the tape layer 2 are in different colors, which can help medical staff to more clearly and intuitively identify the safe side and the needle side of the intradermal needle, reduce the possibility of misoperation, and reduce the risk of needlestick injuries.

[0048] As an alternative embodiment, the plastic layer 1 comprises a polyamide plastic layer 1 .

[0049] The polyamide material of the polyamide plastic layer 1 has good mechanical properties such as strength and flexibility. These properties enable the polyamide plastic layer 1 to deform and fold along the folding groove 11 during the folding process, while effectively preventing the needle body 3 from piercing its surface. Therefore, the needle body 3 can be completely wrapped in the wrapping space.

[0050] It should be noted that the material of the plastic layer 1 includes but is not limited to polyamide materials, and any plastic material with good mechanical strength such as strength and flexibility can be used.
