It should be understood that the specific implementation methods described here are only used to explain the utility model and are not used to limit the utility model.

[0032] Example 1

[0033] See also Figure 1-5 The technical solution of a protective fixing device for a facial nerve stimulation needle provided in this embodiment includes the following:

[0034] The stimulation needle fixing device 1 comprises a stimulation needle fixing part 11 and puncture auxiliary wings 12 provided at both ends of the stimulation needle fixing part 11;

[0035] The stimulation needle reinforcement assembly 2 comprises a first fixing member 21 and a second fixing member 22 connected to each other, wherein the first fixing member 21 is connected to the stimulation needle fixing device 1, and a first connecting member 23 is provided on the second fixing member 22;

[0036] The skin-friendly component 3 is arranged at an end of the stimulation needle fixing device 1 that is not connected to the stimulation needle reinforcement component 2.

[0037] In a specific implementation, the stimulation needle fixing device 1 of the present design is similar to the Ω style. Specifically, the stimulation needle fixing part 11 is in a hollow arc shape, and the size of the hollow accommodation space 13 in the stimulation needle fixing part 11 matches the size of the needle handle 42 of the stimulation needle. The needle handle 42 of the facial nerve stimulation needle 41 is clamped in the accommodation space 13 of the stimulation needle fixing part 11. One side of the stimulation needle fixing device 1 is connected to the first fixing part 21 in the stimulation needle reinforcement assembly 2, and the other end is provided with a skin-friendly part 3. When not in use, the first connecting part 23 on the second fixing part 22 is provided with a coating 24.

[0038] Preferably, the stimulation needle fixing device 1 is made of medical plastics such as polyethylene, polypropylene or polycarbonate, which is light, affordable and has good chemical resistance.

[0039] Preferably, the width of an adult's index finger is usually about 1 cm (0.4 inches), and the length of the area where the index finger and thumb fit together when an adult pinches an object is about 1.5 cm. Therefore, in order to facilitate finger pinching, the length range of the puncture auxiliary wing 12 is set to 1 cm to 2 cm; the width range of the puncture auxiliary wing 12 is set to 0.8 cm to 1.5 cm.

[0040] In a specific implementation, the size of the first fixing member 21 matches the stimulation needle fixing device 1. There are many ways to fix the first fixing member 21 and the stimulation needle fixing device 1. For example, the first fixing member 21 can be provided with the same antibacterial adhesive as that on the second fixing member 22, and the stimulation needle fixing device 1 can be directly adhered to the adhesive after the needle handle 42 is clamped. Other ways to connect the two together are also within the scope of protection of the present utility model.

[0041] Preferably, the length of the stimulation needle commonly used in medicine is about 2 cm. Therefore, in order to completely adhere to the puncture area, the length range of the second fixing member 22 is set to 2 cm to 4 cm; in order to make the adhesion more stable, the width range of the second fixing member 22 is set to 3 cm to 4 cm.

[0042] In a specific implementation, the stimulation needle reinforcement component 2 is similar to the backing in a bandage, and its main function is to serve as a support for the adhesive (the first connector 23 in this design) and the stimulation needle fixing device 1, and to provide a barrier for the puncture area. Therefore, it is made of a flexible material, such as cotton cloth or other fabrics. Of course, flexible plastic materials can also be used in this design. The first connector 23 is an antibacterial adhesive, which is easy to tear and separate, does not leave glue, and usually contains antibacterial agents, such as silver ions, triclosan, silicone quaternary ammonium salts, etc. These antibacterial agents can inhibit the growth and reproduction of microorganisms such as bacteria, fungi, and viruses, thereby reducing the risk of cross infection. Before use, a coating 24 is provided at the end of the first connector 23 that is not connected to the second fixing member 22.

[0043] In a specific implementation, in order to facilitate tearing off the film 24 , a hand rest 25 may be provided at the edge of the second fixing member 22 , and no antibacterial adhesive is provided on the hand rest 25 , so that the hand rest 25 area is not bonded to the film 24 , which facilitates guiding the tearing off of the film 24 .

[0044] Specifically, the style of the skin-friendly component 3 matches the stimulation needle fixing device 1, and the skin-friendly component 3 is a flexible pad, such as a silicone material or a flexible fabric material, which can be used in this design.

[0045] The working principle or working process of the protective fixing device for facial nerve stimulation needle provided by the utility model is as follows: Figure 2 As shown, before puncturing, the second fixing member 22 is slightly folded back, and after the puncture is completed, the puncture auxiliary wing 12 is held. Figure 3 As shown, the covering film 24 on the second fixing member 22 is torn off to expose the first connecting member 23, and the second fixing member 22 is applied to the puncture area through the first connecting member 23 to achieve fixation.

[0046] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions described in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
