Description

Technical Field

[0001] The utility model belongs to the technical field of cosmetic medical equipment, in particular to a hyaluronic acid injection device. Background Art

[0002] Hyaluronic acid is a biochemical drug with high clinical value. It can keep the skin moisturized, smooth, delicate, tender and elastic. It also has anti-wrinkle, anti-wrinkle, beauty and health care, and restores the physiological functions of the skin. Therefore, it is widely used in facial plastic surgery. At present, in the process of facial hyaluronic acid injection, it is generally common to use a syringe directly. During the injection, it is necessary to mark the position on the patient's face to determine the specific location of the needle. When injecting, the syringe is held by the medical staff so that the needle is inserted into the skin tissue at the marked position, and the syringe is pushed with the other hand to complete the injection of hyaluronic acid.

[0003] The particularity of this process is that since the injection site is directly located on the face of the patient, no obvious traces can be left after the injection. In the process of injecting hyaluronic acid with a syringe, when holding the syringe in the hand, it is necessary to ensure that the needle tip is aligned with the marked position, and the shaking or trembling of the hand needs to be overcome during the injection process. If the medical staff is not focused, accidents are inevitable. It can be seen that when injecting through the current equipment, certain operating levels of medical staff are required. In view of this, in order to reduce the difficulty of operation, the present application provides a hyaluronic acid injection device. Utility Model Content

[0025] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0026] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] Reference Figure 1 and Figure 2 One embodiment of the utility model provides a hyaluronic acid injection device, comprising the following parts:

[0030] The fixing part 4 is used to form a fixed connection with the skin tissue so as to maintain a fixed position on the skin and can be removed from the skin when not in operation;

[0031] A support portion 2, which is fixedly connected to the fixing portion 4;

[0032] The needle 3 is used for injection and is slidably connected to the support part 2. The root of the needle 3 is connected to the injection source through a soft catheter 5;

[0033] The driving member is softly connected to the needle 3, and the needle 3 will not be touched when the driving member is operated. Its function is that the needle 3 can slide on the support part 2 through the driving member;

[0034] When the utility model cooperates with medical staff to perform hyaluronic acid injection, the fixing part 4 is connected to the position to be injected on the skin tissue, and the tip of the needle 3 is directed to the position to be inserted. By operating the driving member, the needle 3 slides on the support part 2, so as to be inserted into the target position on the skin, and then the injection source is operated to make the hyaluronic acid liquid flow into the needle 3 through the catheter 5, so as to enter the inserted position on the skin to complete the entire injection process. For the injection source involved in the utility model, an injection head with the needle tip removed can still be used and connected to the catheter 5, or some micro pump body structures can be used, and can meet the requirements of precise control;

[0035] Compared with the prior art, during the operation, the alignment process of the needle 3 is achieved by the cooperation of the fixing part 4 and the supporting part 2, and direct contact of the medical staff's hands is avoided, so that during the insertion process, the needle 3 is not affected by the shaking of the staff's hands, and through the soft connection properties at multiple locations, the medical staff will not cause hard contact with the needle 3 during the operation of the driving part and the injection source. Therefore, the requirements for the stability of the medical staff's hands are reduced as a whole, that is, the high requirements for the medical staff's operating level are reduced, making the operation easier and reducing the occurrence of accidents.

[0036] For other structures involved in the utility model, for example:

[0037] The fixing part 4 can be designed as a sheet-like structure. Figure 1 and Figure 2 , and the fixing part 4 is made of memory metal, so that it can be ravaged into a desired shape before connecting with the skin tissue, so as to better adapt to the injection site on the skin. At this time, the fixing part 4 and the skin tissue can be connected by pasting. The sheet-like structural design can increase the contact area between the fixing part 4 and the skin, thereby increasing the stability effect when fixed on the skin;

[0038] Furthermore, the fixing part 4 can be connected to the skin tissue by adhesive tape, such as using double-sided adhesive tape, so that the pasting process is simple and easy, and as a disposable product, the manufacturing cost can also be reduced;

[0039] Furthermore, a positioning hole 6 is also constructed in the middle of the sheet surface of the fixing part 4, such as Figure 1 and Figure 2 As shown, the needle 3 is directed toward the positioning hole 6, so when the fixing part 4 is pasted on the skin, the part to be pierced is located at the positioning hole 6, thereby encircling the part to be pierced, so that the needle insertion part can be better determined in advance, and when the needle 3 exerts force on the skin, the reaction force on the needle 3 is located in the middle of the entire fixing part, so that the phenomenon of deviation on the skin caused by the needle 3 exerting force can be reduced, thereby increasing the stability of the piercing process;

[0040] For the connection between the support portion 2 and the fixing portion 4, a connection end 7 may be constructed on the fixing portion 4. Figure 1 and Figure 2 As shown, the support portion 2 and the connection end 7 can be fixedly connected. Due to the characteristics of the material of the fixing portion 4, the connection end 7 can also be kneaded into a desired shape by a person applying force thereto in advance, so that the direction of the needle 3 can be finely adjusted in advance, so as to further improve the practical effect of the utility model;

[0041] The support portion 2 can be designed as a cylindrical structure. Figure 1-4 As shown, a slider 8 is fixedly connected to the periphery of the needle 3, and the slider 8 is slidably matched with the inner wall of the support portion 2, so as to meet the sliding requirement of the needle 3 on the support portion 2. The cylindrical structure can protect the needle 3, and at the same time, the slider 8 can maintain non-direct contact between the needle 3 and the support portion 2, so as to avoid contamination of the needle 3.

[0042] Furthermore, based on the cylindrical structure, Figure 3 and Figure 4 One end of the support portion 2 is a closed structure, so that an air storage cavity 9 can be formed between one end of the support portion 2 and the slider 8. At this time, the driving member is used to deliver or inhale air to the air storage cavity 9. When delivering air, the slider 8 is pushed to move by gas expansion, thereby realizing the sliding drive of the slider 8. When inhaling air, the slider 8 slides back by creating a negative pressure in the air storage cavity 9, thereby completing the removal of the needle 3 in the skin tissue. For the driving member, for example, an injection head or a pump body structure can still be used, and it can be connected to the air storage cavity 9 through the soft air tube 1;

[0043] Further, see Figure 3 and Figure 4A guide structure 10 is also constructed on the inner wall of the support portion 2. The guide structure 10 is used to make the slider 8 move linearly only along the axial length direction of the cylinder when sliding, thereby playing a directional guiding effect, thereby preventing the needle 3 from spinning when moving. The guide structure 10 can adopt convex or concave linear patterns, and the shape of the slider 8 can be adapted thereto.

[0044] It will be appreciated that in the development of any actual implementation, as in any engineering or design project, numerous implementation-specific decisions may be made. Such a development effort may be complex and time-consuming, but will be a routine task of design, fabrication, and production for those of ordinary skill having the benefit of this disclosure without undue experimentation.

[0045] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
