Description

Technical Field

[0001] The utility model relates to the technical field of medical beauty, and more specifically, to a disposable injection needle. Background Art

[0002] Medical beauty technology, that is, medical cosmetology technology. While people pay attention to beauty and repairing their appearance, they are paying more and more attention to health. This makes people feel that relying solely on cosmetics to maintain the skin has more and more side effects, so some people have proposed the concept of medical cosmetology technology, that is, relying on medical methods to maintain the skin and repair the appearance. Medical cosmetology technology has quickly occupied the beauty market with its fewer side effects and faster results. Water injection is currently a commonly used medical beauty technology. The required beauty injection is injected into the dermis close to the epidermis. After the injection, it can make the skin hydrated and bright, hence the name. However, most of the existing syringes have only 4 to 6 needles, and the injection efficiency is slow. After the injection, it is easy to cause the subcutaneous absorption of liquid to be slower, and the liquid accumulates locally under the skin, resulting in bulging of the skin after the injection is completed.

[0003] Therefore, the utility model provides a disposable injection needle. Utility Model Content

[0006] A further preferred solution: the needle seat is in the shape of a cross diamond, and 9 fixing holes are provided on the bottom surface of the needle seat.

[0007] A further preferred solution is that grooves are provided on the sides of the top end of the needle seat, and the grooves are in the shape of an inverted triangle.

[0008] A further preferred solution is that the adjusting knob is threadedly connected to the lower end surface of the liquid guide joint, the adjusting knob is threadedly connected to the top end of the pinhole tube, and the upper cover plate is located inside the adjusting knob and the pinhole tube.

[0009] A further preferred solution is that a groove is formed at the bottom end of the upper cover plate, and the shape of the groove is the same as the shape of the needle seat surface.

[0010] A further preferred solution is that the number of the pinholes is 9 in total, the bottom end of the needle seat is located at the top end of the pinhole, and the fixing hole opened at the bottom end of the needle seat is aligned with the position of the pinhole.

[0011] A further preferred solution is that the pinhole outlet is located inside the side wall at the bottom end of the pinhole tube, and an inner groove is provided on the side wall at the bottom end of the pinhole tube.

[0012] Beneficial effects:

[0013] By providing an inverted triangular groove on the side of the needle seat, the stability of the needle seat embedded in the upper cover plate can be enhanced; by providing the needle seat and the needle hole, the needle can be prevented from shaking during movement; by providing an inner groove on the side wall of the bottom end of the needle hole tube, the contact area between the liquid and the skin can be increased, thereby improving the efficiency of the skin absorbing the liquid, thereby preventing the user's skin from bulging after injection.

[0018] The following will be combined with the attached embodiment of the utility model Figure 1-Figure 3 , clearly and completely describe the technical solutions in the embodiments of the utility model.

[0019] See also Figure 1-3 In the embodiment of the utility model, a disposable injection needle comprises a liquid guide joint 1, the surface of the liquid guide joint 1 is connected with an adjusting knob 2, the bottom end of the adjusting knob 2 is connected with a pinhole tube 3, a pinhole 6 is opened in the pinhole tube 3, the bottom end of the liquid guide joint 1 is fixedly connected with an upper cover plate 5, a needle seat 4 is embedded and installed in the upper cover plate 5, firstly, the bottom end of the pinhole tube 3 is brought into contact with the skin surface, and then the adjusting knob 2 is rotated, and the needle seat 4 is moved downward by rotating the adjusting knob 2, so that the needle tip is inserted into the skin surface along the outlet of the pinhole 6, and then the liquid is injected into the dermis of the skin, and the injection efficiency can be improved by providing 9 pinholes 6, and the contact area between the liquid and the skin can be increased by providing the outlet of the pinhole tube 3 at the bottom end of the pinhole tube 3, thereby improving the efficiency of the skin absorbing the liquid, thereby preventing the liquid from forming local accumulation under the skin, which causes bulging of the skin after injection.

[0020] In the embodiment of the utility model, the needle seat 4 is shaped like a cross diamond, 9 fixing holes are provided on the bottom surface of the needle seat 4, grooves are provided on the top side of the needle seat 4, and the grooves are in the shape of an inverted triangle. A groove is provided at the bottom of the upper cover 5, and the shape of the groove is the same as the surface shape of the needle seat 4. By providing an inverted triangle groove on the side of the needle seat 4, the stability of the needle seat 4 embedded in the upper cover 5 can be enhanced.

[0021] When in use, the needle seat 4 is directly embedded in the groove opened in the upper cover plate 5. Since the needle seat 4 is in the shape of a cross diamond, the needle seat 4 can be prevented from moving horizontally in the groove. The inverted triangle-shaped groove opened on the side of the needle seat 4 can increase the limiting contact area of ​​the groove opened in the upper cover plate 5 on the needle seat 4, thereby enhancing the stability of the needle seat 4 in the upper cover plate 5.

[0022] The adjusting knob 2 is threadedly connected to the lower end surface of the liquid guide connector 1, and the adjusting knob 2 is threadedly connected to the top of the pinhole tube 3. The upper cover plate 5 is located inside the adjusting knob 2 and the pinhole tube 3. There are a total of 9 pinholes 6. The bottom end of the needle seat 4 is located at the top of the pinhole 6, and the fixing hole opened at the bottom end of the needle seat 4 is aligned with the position of the pinhole 6. The needle seat 4 and the pinhole 6 can prevent the needle from shaking during movement.

[0023] First, fix the needle input end on the needle seat 4 through the fixing hole provided in the needle seat 4, and then insert the needle output end into the needle hole 6. When in use, the upper cover plate 5 is driven downward by turning the adjusting knob 2, and then the needle seat 4 is driven downward to make the needle output end extend along the needle hole 6, thereby preventing the needle from shaking during use and enhancing the stability of the needle during use.

[0024] The outlet of the needle hole 6 is located inside the side wall of the bottom end of the needle hole tube 3, and an inner groove is provided on the side wall of the bottom end of the needle hole tube 3. By providing the inner groove on the side wall of the bottom end of the needle hole tube 3, bulging of the user's skin after injection can be prevented.

[0025] When in use, the bottom end of the pinhole tube 3 is brought into contact with the skin surface. Since the outlet of the pinhole 6 is located inside the bottom end of the pinhole tube 3, there is a gap between the pinhole tube 3 and the skin at this time, thereby increasing the contact area between the liquid and the skin during injection, thereby improving the efficiency of the skin absorbing the liquid, thereby preventing the liquid from accumulating locally under the skin, causing bulging of the skin after injection.
