[0019] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0020] Please refer to Figure 1 - Figure 4 The environment-friendly super-hydrophilic medical and cosmetic needle comprises an injection tube 1 and a piston rod 2 slidingly arranged in the injection tube 1, and the front end of the injection tube 1 is further provided with a needle head 102, the outer surface of the needle head 102 is provided with a hydrophilic coating 103, the hydrophilic coating 103 extends from the root of the needle head 102 to the tip position, the hydrophilic coating 103 can reduce the friction between the needle head 102 and the skin during injection, making the injection process more smooth and comfortable, and because the hydrophilic coating 103 can form a water film on the surface of the injection needle 102, which is consistent with the water film on the surface of the human tissue, this lubrication can significantly reduce the pain and discomfort during injection, so that the needle 102 can be inserted into the user's skin more smoothly, reducing the user's discomfort, and the function of the hydrophilic coating 103 will be described in detail below:

[0021] The hydrophilic coating 103 can reduce the friction between the needle head 102 and the skin during injection, making the injection process more smooth and comfortable. Because the hydrophilic coating 103 can form a water film on the surface of the injection needle 102, which is consistent with the water film on the surface of the human tissue, this lubrication can significantly reduce the pain and discomfort during injection, improve the patient's injection experience.

[0022] On the other hand, the application of the hydrophilic coating 103 can also reduce the friction and damage during injection, thereby reducing the risk of subcutaneous blood stasis and infection after injection. In the traditional injection process, the friction between the needle 102 and the skin may cause damage to the skin tissue, increasing the possibility of infection. The hydrophilic coating 103 can effectively reduce this friction and protect the integrity of the skin tissue, thereby reducing the risk of infection.

[0023] In this embodiment, a sleeve ring 3 is slidingly arranged on the outer side wall of the injection tube 1, the sleeve ring 3 and the piston rod 2 are synchronous, and a plurality of quantitative plates 4 are rotatably arranged on the outer side wall of the injection tube 1, the plurality of quantitative plates 4 are equidistantly arranged on the same side of the injection tube 1, and the sleeve ring 3 is provided with an opening 301 corresponding to the position of the quantitative plate 4, so that when the piston rod 2 drives the sleeve ring 3 to move synchronously to the position of the needle head 102, the quantitative plate 4 will pass through the opening 301, so that the movement of the sleeve ring 3 is not blocked, and the drug can be injected out of the injection tube 1.

[0024] The width of the quantitative plate 4 is less than the width of the opening 301, and the height of the quantitative plate 4 is greater than the width of the opening 301. In this embodiment, when the quantitative plate 4 is in the state as shown in Figure 4 , the width of the quantitative plate 4 is less than the width of the opening 301, so that the sleeve ring 3 can continue to descend; and when the quantitative plate 4 is turned over by 90°, the height of the quantitative plate 4 becomes the width, so that the quantitative plate 4 cannot pass through the opening 301, thereby blocking the movement of the sleeve ring 3.

[0025] Further, the outer side wall of the injection tube 1 has a plurality of scale lines arranged at equal intervals, and the plurality of quantitative plates 4 are arranged in one-to-one correspondence with the plurality of scale lines, so that the staff can control the moving position of the sleeve 3 by rotating the quantitative plate 4 at the corresponding position, thereby controlling the pushing depth of the piston rod 2, and achieving the purpose of controllable injection dose.

[0026] In order to make the process of synchronous movement of the sleeve 3 and the piston rod 2 more clear, the needle holder 101 is fixedly arranged at the end of the injection tube 1 away from the needle 102, the connecting rod 302 is fixedly arranged on the side of the sleeve 3 opposite to the needle holder 101, the connecting rod 302 penetrates the needle holder 101, and the end of the connecting rod 302 is fixedly connected to the end of the piston rod 2 away from the piston, so that when the piston rod 2 is pushed, the piston rod 2 drives the sleeve 3 to move synchronously towards the needle 102 through the connecting rod 302.

[0027] Further, the needle holder 101 is slidably provided with the slide rod 5, and the slide rod 5 vertically penetrates the needle holder 101; when the top end of the slide rod 5 is attached to the upper surface of the needle holder 101, the bottom end of the slide rod 5 penetrates the plurality of quantitative plates 4, so that when the slide rod 5 penetrates the quantitative plates 4, the quantitative plates 4 can be fixed, thereby avoiding the quantitative plates 4 from continuing to rotate.

[0028] In order to make the process of fixing the quantitative plates 4 by the slide rod 5 more clear, the first through hole 401 and the second through hole 402 are respectively arranged on the upper and lower sides and the left and right sides of the quantitative plate 4; when the slide rod 5 penetrates the first through hole 401 or the second through hole 402, the quantitative plate 4 is in a fixed state, so that when the slide rod 5 penetrates the first through hole 401 or the second through hole 402, the corresponding quantitative plate 4 can be fixed, thereby not rotating on the side wall of the injection tube 1. The vertical and horizontal holes are arranged on the quantitative plate 4, and the purpose is that after one of the quantitative plates 4 rotates, the slide rod 5 can still penetrate all the quantitative plates 4, thereby changing the state of the quantitative plate 4, and finally fixing all the quantitative plates 4 on the side wall of the injection tube 1, and achieving the effect of controlling the moving position of the sleeve 3

[0029] The working principle and use process of the utility model are as follows: first, the medicament is sucked into the injection tube 1 through the needle 102, then the required injection dose is calculated according to the customer demand and injection area, the quantitative plate 4 on the corresponding scale line is rotated according to the dose, the slide rod 5 is pulled to the outside of the quantitative plate 4 to be rotated, the quantitative plate 4 is controlled to rotate 90°, so that the quantitative plate 4 on the scale line cannot penetrate the gap 301, and then the injection can be started.

[0030] When injecting, the piston rod 2 is pushed, and the piston rod 2 drives the sleeve ring 3 to move synchronously to the needle 102 through the connecting rod 302 until the flip 90° dosing plate 4 touches the sleeve ring 3, thereby blocking the sleeve ring 3 from continuing to move downward, and further blocking the piston rod 2 from continuing to push, so that the injection dose is accurately controlled, convenient and fast, and the health and safety of the user are guaranteed.

[0031] Although the embodiments of the present application have been shown and described, it should be understood by those ordinary skilled in the art that various changes, modifications, replacements and modifications can be made to these embodiments without departing from the principles and spirits of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
