Description

Technical Field

[0001] This utility model relates to the field of cosmetic needles and related technologies, specifically a structure for a facial cosmetic injection needle. Background Technology

[0002] In the existing facial cosmetic injection needle structure, most needles have a fixed length, which is obviously insufficient when facing the injection length requirements of different parts of the face. For example, the skin around the eyes is thinner and the tissue is more fragile, requiring a shallower injection depth, while the skin on the cheeks is relatively thicker, requiring a deeper injection depth to achieve the ideal cosmetic effect. However, traditional fixed-length needles cannot flexibly adjust the injection depth according to the needs of different parts, which can easily lead to poor injection results.

[0003] Currently, there are many inconveniences in the disinfection methods for facial cosmetic injection needles. In clinical practice, the commonly used disinfection method is to wipe the needle with a separate cotton ball soaked in disinfectant. This method is relatively cumbersome, requiring medical staff to perform disinfection before and after injection, which increases the operation time. Moreover, the separate cotton ball is easily contaminated by external factors during use, and its storage and carrying are not convenient. In addition, this wiping disinfection method may not be able to ensure that all parts of the needle are thoroughly disinfected, posing a risk of incomplete disinfection and increasing the possibility of cross-infection. For example, in places such as beauty clinics, if multiple patients are given injections consecutively, incomplete needle disinfection may lead to the spread of pathogens such as bacteria and viruses between patients, causing infectious diseases and posing a serious threat to the health of patients.

[0004] In summary, existing facial cosmetic injection needle structures have many problems in terms of injection depth control and needle sterilization. There is an urgent need for a new needle structure that can effectively solve these problems in order to improve the safety, effectiveness, and convenience of facial cosmetic injections.

The end of the first cylinder with the groove is fixedly provided with a circular hole plate, and the center of the circular hole plate has a hole that matches the injection needle, so that the injection needle can extend and retract within the central hole of the circular hole plate.

[0010] Preferably, the first cylinder can rotate by being threaded onto the outer wall of the threaded cylinder.

[0011] Preferably, the disinfection device includes a second cylinder, a first membrane, a second membrane, a first chamber, a second chamber, a third chamber, disinfectant cotton, a circular shell, and a fixed circular plate. The inner cavity of the second cylinder is divided into three equidistant chambers at the top, middle, and bottom. The three equidistant chambers at the top, middle, and bottom of the inner cavity of the second cylinder are arranged in the order of the first chamber, the second chamber, and the third chamber. The first chamber can be inserted into one end of the first cylinder with a groove. The first chamber and the second chamber are separated by a first membrane, and the second chamber and the third chamber are separated by a second membrane. One end of the second cylinder is provided with a circular shell that can be inserted, and the outer wall of the circular shell is in contact with the inner wall of one end of the second cylinder. A fixed circular plate is fixedly provided at one end of the circular shell.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-8 This utility model provides a technical solution: a special needle structure for facial cosmetic injection, including an injection device 1, a moving device 2 and a sterilization device 3. The bottom end of the injection device 1 is fitted with a rotatable moving device 2, and the bottom end of the moving device 2 is provided with a sterilization device 3 that can be inserted.

[0028] As a preferred embodiment, the injection device 1 further includes a circular plate 11, a circular rod 12, a stopper 13, a threaded cylinder 14, a first cavity 15, a small cylinder 16, and an injection needle 17. One end of the circular plate 11 is disposed at one end of the circular rod 12, and the other end of the circular rod 12 is fixedly disposed with the stopper 13. The stopper 13 can be inserted into the first cavity 15 at one end of the threaded cylinder 14. The stopper 13 has a certain sealing and elasticity, and the stopper 13 can move and extend within the first cavity 15 at one end of the threaded cylinder 14, so that the outer wall of the stopper 13 contacts the inner wall of the threaded cylinder 14. The other end of the threaded cylinder 14 is fixedly disposed at one end of the small cylinder 16, and the other end of the small cylinder 16 is fixedly disposed with the injection needle 17.

[0029] As a preferred embodiment, the stopper 13 can move and extend within the first cavity 15 of the threaded cylinder 14 via the circular plate 11. When the stopper 13 is within the first cavity 15 and is close to the bottom of the small cylinder 16 and the threaded cylinder 14, the circular plate 11 is pulled to drive the circular rod 12 to drive the stopper 13, which in turn absorbs the injection fluid through the injection needle 17 and stores it in the first cavity 15. When the first cavity 15 contains the injection fluid, the circular plate 11 is pushed to drive the circular rod 12 to drive the stopper 13, so that the injection fluid is expelled outward through the injection needle 17 by the compression of the stopper 13.

[0030] As a preferred embodiment, the moving device 2 further includes a first cylinder 21, a second cavity 22, a groove 23, a thread 24, and a circular hole plate 25. The inner cavity of the first cylinder 21 has a through second cavity 22. The inner wall of the first cylinder 21 is provided with a thread 24, which matches the thread cylinder 14. A groove 23 is provided on the outer wall of one end of the first cylinder 21. A circular hole plate 25 is fixedly provided at the end of the first cylinder 21 with the groove 23. The center of the circular hole plate 25 has a hole that matches the injection needle 17, so that the injection needle 17 can extend and retract within the central hole of the circular hole plate 25. When injecting into shallower areas such as around the eyes, the first cylinder 21 can be rotated and moved to make the exposed length of the injection needle 17 shorter. When injecting into deeper areas such as the cheeks, the first cylinder 21 can be rotated and moved to make the exposed length of the injection needle 17 longer.

[0031] As a preferred embodiment, the first cylinder 21 can be rotated by fitting the outer wall of the threaded cylinder 14 through the thread 24. The second cavity 22 at the other end of the first cylinder 21 can be fitted with the other end of the threaded cylinder 14, so that the first cylinder 21 can rotate and move on the outer wall of the threaded cylinder 14 through the thread 24. The length of the injection needle 17 exposed can be controlled. When 21 moves to the designated position of the injection needle 17, the hole in the center of the circular plate 25 can fix the injection needle 17, making the injection needle 17 more secure and reducing shaking during use.

[0032] As a preferred embodiment, the disinfection device 3 further comprises a second cylinder 31, a first membrane 32, a second membrane 33, a first chamber 34, a second chamber 35, a third chamber 36, disinfectant cotton 37, a circular shell 38, and a fixed circular plate 39. The inner cavity of the second cylinder 31 is divided into three equidistant chambers: upper, middle, and lower. The order of these three equidistant chambers is first chamber 34, second chamber 35, and third chamber 36. The first chamber 34 can be inserted into one end of the first cylinder 21 with a groove 23. The first chamber 34 and the second chamber 35 are separated by the first membrane 32, and the second chamber 35 and the third chamber 36 are separated by the second membrane 33. The second chamber 35 contains iodine solution. The injection needle 17 is inserted into the inner cavity of the second cylinder 31. The injection needle 17 is disinfected by the disinfectant cotton 37. The disinfectant cotton 37, when wetted with iodine, can effectively kill any bacteria, viruses and other microorganisms that may remain on the injection needle 17, reducing the risk of infection. It is stored and sealed by the first film 32 and the second film 33. One end of the second cylinder 31 is provided with a cylindrical shell 38 that can be inserted, and the outer wall of the cylindrical shell 38 is in contact with the inner wall of one end of the second cylinder 31. A fixing plate 39 is fixedly provided at one end of the cylindrical shell 38. The disinfectant cotton 37 is fixedly provided in the inner cavity of the cylindrical shell 38, and one end of the disinfectant cotton 37 is in contact with one side of the cylindrical shell 38. When the cylindrical shell 38 is inserted into one end of the second cylinder 31, the disinfectant cotton 37 can be stored in the third chamber 36.

[0033] The detailed connection method is a well-known technology in this field. The following mainly introduces the working principle and process. When using this device, place the end with the disinfection device 3 downwards and then start it. The specific operation is as follows: because the thread 24 of the inner cavity of the moving device 2 matches the outer wall of the threaded cylinder 14, and the moving device 2 can rotate on the outer wall of the threaded cylinder 14, and can rotate to the end with the first cavity 15, when the moving device 2 rotates to the end with the first cavity 15, the moving device 2 drives the disinfection device 3 to move to the end with the first cavity 15. At the same time, the needle of the injection needle 17 enters the inner cavity of the disinfection device 3, and the injection needle 17 punctures the first membrane 32 and the second membrane 33 one by one. Because the second chamber 35 contains iodine, the second membrane 33 at the bottom of the iodine in the second chamber 35 is injected. The hole punctured by the injection needle 17 allows iodine-soaked disinfectant cotton 37 to leak in. This not only disinfects the outer wall of the injection needle 17 during the process of puncturing the second membrane 33, but also allows the disinfectant cotton 37 to be fully soaked with iodine in a closed environment. After the above steps are completed, one end of the second cavity 22 is rotated to the end with the first cavity 15. Since the moving device 2 and the disinfection device 3 are connected by a plug, the disinfection device 3 is pulled out, and the injection needle 17 is fully exposed. The injection needle 17 is aligned with the injection liquid. By pulling the circular plate 11, the circular rod 12 drives the stopper 13, and the injection liquid is stored in the inner cavity of the threaded cylinder 14 through the suction of the stopper 13. The length of the injection needle 17 exposed can be adjusted by rotating the moving device 2, and the length of the injection needle 17 entering the human body can be controlled.
