When sharp needles penetrate the skin, their pointed tips can easily cause pain to the patient, and improper operation can damage the skin, blood vessels, and nerves, leading to serious consequences such as redness, swelling, pain, bruising, scarring, and even vascular embolism. Utility Model Content
[0003] In view of the shortcomings of the existing technology, the technical problem to be solved by this utility model is to provide a cosmetic injection needle and cosmetic injection device, which aims to improve the safety of the injection process, reduce patient pain, and facilitate operation and postoperative recovery.
[0004] To solve the above-mentioned technical problems, this utility model provides a cosmetic injection needle, comprising:
[0005] A needle hub, said needle hub being made of a first material, including a needle hub opening;
[0006] The needle tube is made of a second material and includes a connecting section connected to the needle hub and a needle tip section connected to the connecting section. The end of the needle tip section away from the needle hub has a fully enclosed structure, and at least one injection port is provided on the side of the needle tip section. The injection port communicates with the opening of the needle hub through the needle tube.
[0007] The first material is different from the second material, and the needle hub is less flexible than the needle tube.
[0008] In one possible implementation, the fully enclosed structure is an outwardly convex enclosed structure, and the fully enclosed structure is integrally formed with the needle tip segment.
[0009] In one possible implementation, the fully enclosed structure is an outwardly convex enclosed structure, and the outer contour of the outwardly convex enclosed structure is an arc-shaped structure.
[0010] In one possible implementation, the injection port includes a first injection port and a second injection port, the distance between the first injection port and the second injection port in the direction of needle length extension is at least 2 mm, and both the first injection port and the second injection port are in communication with the needle seat opening.
[0011] In one possible implementation, the connecting segment is integrally formed with the needle tip segment, and the length of the connecting segment is greater than the length of the needle tip segment.
[0012] In one possible implementation, the outer circumferential surface of the needle tube is provided with a plurality of scale lines evenly spaced along the length of the needle tube.
[0013] In one possible implementation, the scale lines comprise a luminescent material, and the width of the scale lines is less than or equal to 1 mm.
[0014] In one possible implementation, the flexibility of the needle tip segment is greater than or equal to the flexibility of the connecting segment.
[0015] In one possible implementation, the injection port is an elliptical hole that is concave and transitions to the inner wall by an arc, and the major axis of the elliptical hole is less than or equal to 2 mm.
[0016] This utility model also provides a cosmetic injection device, including: a syringe body and a cosmetic injection needle as described above, wherein the syringe body and the cosmetic injection needle are detachably connected.
[0017] Compared to existing technologies, the beneficial effects of this utility model are as follows: The cosmetic injection needle of this application includes a needle hub and a needle tube. The needle hub is made of a first material and includes a needle hub opening; the needle tube is made of a second material and includes a connecting section connected to the needle hub and a needle tip section connected to the connecting section. The end of the needle tip section away from the needle hub includes a fully enclosed structure, and at least one injection port is opened on the side of the needle tip section. The injection port communicates with the needle hub opening through the needle tube. The first material and the second material are different, and the flexibility of the needle hub is less than that of the needle tube. Thus, the needle tube of this application is soft and elastic, and the drug outlet is designed on the side of the needle tube, rather than the tip of a traditional sharp needle. This design allows the blunt needle to smoothly advance into soft tissue during operation, and when encountering blood vessels and nerves, it can naturally slide away without puncturing them, thereby significantly reducing the probability of bleeding, swelling, nerve damage, and other problems.

[0021] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0022] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating positions or relationships, are based on the positions or relationships shown in the accompanying drawings and are intended solely to facilitate the description of this utility model and simplify the description. They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0023] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integrated connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components; and they can refer to a wireless connection or a wired connection. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Example
[0024] like Figure 1 As shown, the cosmetic injection needle of this utility model mainly comprises two parts: a needle hub 100 and a needle tube 200. The needle hub 100 is made of a primary material such as rigid plastic, providing good structural stability and a comfortable grip. It has a needle hub opening 110 for connecting a syringe or a drug container. The needle tube 200 is made of a secondary material with good flexibility, such as silicone or elastic metal, to ensure its smooth and safe passage through soft tissue.
[0025] The needle tube 200 includes a connecting section 210 tightly connected to the needle hub 100 and a needle tip section 220 located away from the needle hub. The end of the needle tip section 220 is designed as a fully enclosed structure with an outwardly convex arc shape, integrally formed with the needle tip section 220, effectively avoiding the risk of puncture wounds that may be caused by traditional sharp needles. At least one injection port 221 is evenly provided on the side of the needle tip section 220; in this embodiment, there are two injection ports, namely a first injection port 230 and a second injection port 240, spaced at least 2 mm apart along the length of the needle tube to ensure a wide and uniform injection area. These injection ports are all connected to the needle hub opening 110 through an internal channel in the needle tube, allowing the medication to flow out smoothly. Example
[0026] Based on Example 1, this example further optimizes the injection port 221. For example... Figure 2 As shown, the injection port is designed as an elliptical hole that is concave and transitions to the inner wall with an arc. Its major axis length is less than or equal to 2mm, in order to control the speed and direction of the liquid flow, reduce the liquid spraying phenomenon, and improve the injection accuracy. Example
[0027] To facilitate depth control during operation, this embodiment provides multiple evenly spaced graduation lines 250 along the length direction on the outer circumferential surface of the needle tube 200 (e.g., Figure 2 (As shown). These graduations not only provide intuitive depth indications, but are also made of luminescent material, ensuring clear visibility even in low-light conditions. Their width is controlled to within 1mm, guaranteeing both clarity and avoiding any adverse impact on the overall flexibility of the syringe. Example
[0028] To further enhance the safety and comfort of the injection needle, this embodiment places particular emphasis on the flexible design of each part of the needle tube. Specifically, the flexibility of the needle tip 220 is designed to be greater than or equal to that of the connecting section 210, allowing the needle tip to glide more smoothly when contacting and penetrating soft tissue, reducing resistance and patient discomfort. At the same time, the connecting section 210 maintains sufficient strength and stability to ensure a secure connection with the needle hub and the reliability of the overall structure. Example
[0029] like Figure 3 As shown in the illustration, this application also provides a cosmetic injection device integrating the aforementioned cosmetic injection needle, which aims to provide users with a more convenient, efficient, and safe cosmetic injection experience. This cosmetic injection device mainly includes a syringe body 300 and the aforementioned cosmetic injection needle. The syringe body 300, as the main part of the device, integrates key functions such as drug storage, pressure control, and injection volume adjustment, ensuring the accuracy and controllability of the injection process.
[0030] The syringe body 300 and the cosmetic injection needle are connected in a detachable manner. This design not only makes it easy for users to change to different specifications or types of cosmetic injection needles according to actual needs, but also facilitates the cleaning, disinfection and maintenance of the injection needle, ensuring the hygiene standards and safety of each injection.
[0031] In actual use, users simply need to correctly connect the selected cosmetic injection needle to the syringe body 300, and then adjust the injection parameters as needed, such as injection volume and injection speed, to begin the injection procedure. Because the cosmetic injection needle uses a fully enclosed needle tip design, a side injection port layout, and flexible materials, the entire injection process is safer and more comfortable, reducing patient pain and the risk of adverse reactions.
[0032] In addition, the syringe body 300 can also be equipped with a display screen, buttons and other operating interfaces, as well as an alarm system. The injection status is monitored through a liquid level sensor, the display screen is used to show the injection status, receive user instructions, and issue alarms in a timely manner when abnormal situations occur, further improving the safety and ease of use of the device.
[0033] Based on this, the needle tip of this application is blunt, soft, and elastic, and the drug outlet is designed on the side of the needle tube, rather than the tip of a traditional sharp needle. This design allows the blunt needle to advance smoothly into soft tissue during operation, and when it encounters blood vessels and nerves, it can slide away naturally without puncturing them, thereby significantly reducing the probability of bleeding, swelling, nerve damage, and other problems.
[0034] Obviously, the above are only preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the contents of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
