Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a cosmetic needle with a superhydrophobic coating structure. Background Technology

[0002] Cosmetic syringes are commonly used tools in cosmetic medicine to precisely inject liquids such as drugs, nutrients, or fillers into the skin or subcutaneous tissue to achieve cosmetic effects.

[0003] When administering cosmetic injections, ensuring the syringe remains stable and does not wobble is crucial, as this directly affects the accuracy and safety of the injection. Currently, when administering cosmetic injections, the user typically holds the syringe between the index and middle fingers of their right hand, gently placing their thumb on the plunger to push the plunger and inject. The left hand is then placed in a V-shape on the client's face, with the left thumb supporting the bottom of the syringe for added stability.

[0004] However, when the syringe is pressed against the left thumb, the user needs to insert the needle obliquely into the client's skin. At this point, the syringe needs to be pushed to move the needle. Because the syringe is pressed against the thumb, the friction is relatively high. Therefore, the tip of the syringe may slightly deviate during the insertion process. For cosmetic surgery, the insertion position of the syringe must be very precise. If the needle deviates even slightly, it may lead to unsatisfactory cosmetic results and may even cause health hazards to the client.

[0005] To address these shortcomings, we propose a cosmetic syringe with a superhydrophobic coating structure. Utility Model Content

DETAILED DESCRIPTION

[0021] 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 of the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the utility model.

[0022] Please refer to Figure 1 - Figure 4 A cosmetic needle tube with a super-hydrophobic coating structure comprises an injection tube 1 and a piston rod 2 slidingly arranged in the injection tube 1. When injecting, the user usually holds the injection tube 1 with the right index finger and middle finger, and pushes the piston with the thumb to inject. The left hand is placed in a spread manner on the customer's face, and the left thumb is abutted against the bottom of the injection tube 1 to make the injection tube 1 more stable.

[0023] It is worth mentioning that the front end of the injection tube 1 is also provided with a needle stem 7, and the outer surface of the needle stem 7 has a super-hydrophobic coating 8. The super-hydrophobic coating 8 extends from the root of the needle stem 7 to the outer position of the tip. Since the super-hydrophobic coating 8 can reduce the adhesion of liquid on the surface of the needle, it can also effectively prevent the attachment and breeding of bacteria, viruses and other microorganisms on the surface of the needle, thereby reducing the risk of cross infection.

[0024] The outer side wall of the injection tube 1 is axially slidingly connected with a stabilizing sleeve 3. In the initial state, the stabilizing sleeve 3 is located near the needle of the injection tube 1. When the injection tube 1 moves, the stabilizing sleeve 3 can remain in a relatively static state, so that when the needle is inserted into the skin, the fingers of the staff will not interfere with the movement of the injection tube 1, avoiding deviation of the needle insertion position. The side wall of the stabilizing sleeve 3 is helically inserted with an auxiliary seat 4, so that the auxiliary seat 4 can be detached when the injection tube 1 is not in use, facilitating storage. The auxiliary seat 4 is used to fit the user's thumb to assist in fixing the injection tube 1, so that the thumb of the staff can fit the inner side wall of the auxiliary seat 4 when assisting in fixing the injection tube 1, preventing the fingers from detaching from the device.

[0025] In this embodiment, the auxiliary seat 4 includes an arc segment and a stud segment, and the outer surface of the stabilizing sleeve 3 is provided with a threaded hole matched with the stud segment, so that the auxiliary seat 4 can be conveniently installed and detached.

[0026] On the other hand, the outer surface of the injection tube 1 is covered with a hydrophobic coating. The hydrophobic coating has the characteristic of low surface energy, which means it can reduce the interaction between liquid and the outer wall of the syringe. During the medical injection process, the hydrophobic coating has a hydrophobic dirt prevention function, which can prevent the injection tube 1 from being contaminated by liquid, and is beneficial to keeping the injection tube 1 clean.

[0027] Further, a slide rod 101 is fixed on the side wall of the injection tube 1, the slide rod 101 is distributed along the axial direction of the injection tube 1, the slide rod 101 and the stabilizing sleeve 3 are in sliding fit, so that the stabilizing sleeve 3 cannot rotate on the outside of the injection tube 1, and is more stable. Figure 1 As shown in the figure, the top end of the slide rod 101 extends to the outside of the stabilizing sleeve 3, and the width of the end is greater than the width of other parts of the slide rod 101, so that when the stabilizing sleeve 3 moves to the end position, it cannot move upward any more, avoiding the stabilizing sleeve 3 sliding back and forth during injection.

[0028] In order to make the injection tube 1 more stable during use, the finger groove group 5 is arranged on the outer side wall of the stabilizing sleeve 3, the finger groove group 5 includes an index finger groove 501 and a middle finger groove 502, and anti-skid grooves 503 are arranged equidistantly along the respective paths in the index finger groove 501 and the middle finger groove 502, so that the staff can use the thumb, index finger and middle finger of the left hand to clamp the stabilizing sleeve 3 during injection, and the other fingers of the left hand are placed on the side wall of the injection tube 1 to complete the clamping and fixing of the injection tube 1 and the stabilizing sleeve 3, and the anti-skid grooves 503 increase the friction force of clamping to avoid the fingers slipping out of the grooves.

[0029] Specifically, the index finger groove 501 and the middle finger groove 502 are located on the same side of the stabilizing sleeve 3, and the auxiliary seat 4 is located on the other side of the stabilizing sleeve 3, so that the fingers can be naturally placed in the corresponding grooves during clamping, improving the feeling of use experience.

[0030] In the embodiment, two needle holders 6 are fixed on the top side wall of the injection tube 1 in a symmetrical distribution, anti-dropping grooves 601 are arranged on the side of the two needle holders 6 opposite to the stabilizing sleeve 3, and the anti-dropping grooves 601 are in an arc shape, so that the index finger and the middle finger of the right hand can be placed in the anti-dropping grooves 601 during injection, so that the clamping and fixing of the injection tube 1 is more stable.

[0031] The working principle and use process of the utility model are as follows: first, during use, the right index finger and middle finger clamp the syringe at the needle holder 6, at this time the two fingers enter the anti-dropping grooves 601 to prevent slipping, the thumb is placed on the piston rod 2 to push the piston for injection, the left hand is placed in a spread shape on the customer's face, and the thumb of the left hand is abutted on the injection tube 1 at the position of the auxiliary seat 4, so that the thumb and the inner side wall of the auxiliary seat 4 are attached, and the injection tube 1 is more stable.

[0032] Subsequently begin to insert the needle into the skin of the customer, the staff with the right hand push injection tube 1, drive the needle to the customer skin direction movement, at this time, because the auxiliary seat 4 is arc-shaped, is blocked by the staff left thumb movement, so that the stabilizing sleeve 3 and auxiliary seat 4 are in a static state, when the needle is inserted into the skin, the stabilizing sleeve 3 and will touch the top of the slide bar 101, thereby blocking the injection tube 1 continue to move, at this time, can push the piston rod 2 and inject the drug into the skin, if worry about the stability of injection tube 1 is not enough, can be put into the index finger slot 501 and middle finger slot 502 with the auxiliary seat 4 on the thumb cooperation, reach the purpose of clamping fixed injection tube 1, and injection tube 1 is more stable, improve the security.In addition, it is worth mentioning that when not need to use injection tube 1, can be disassembled auxiliary seat 4, convenient storage.

[0033] Although the embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present application, the scope of which is defined by the appended claims and their equivalents.
