[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Many specific details are set forth in the following description to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0025] like Figures 1-5 As shown, this utility model discloses an improved guide wire retainer, including a guide wire fastening structure 1 and a fixing structure 2. The guide wire fastening structure 1 includes a fastening body 11, a fastening knob 12, and a rubber stopper 13. Please refer to... Figure 5 The fastening body 11 is cylindrical, with one end being a hollow flexible reducer 111. Specifically, the flexible reducer 111 is composed of multiple flexible clamping plates 1111, which can be made of polyethylene. One end of the flexible clamping plate 1111 is integrally formed with the fastening body 11, while the other end extends outward, meaning the diameter of the end of the flexible reducer 111 away from the fastening body 11 is larger than the diameter of the end closer to the fastening body 11. The multiple flexible clamping plates 1111 are arranged at equal intervals along the circumference of the fastening body 11. The middle of the fastening body 11 has an external thread for connecting with the internal thread of the fastening knob 12, and the length of the external thread is greater than the length of the fastening knob 12. Multiple equally spaced anti-slip protrusions 112 are integrally formed on the outer side of the other end of the fastening body 11, and the anti-slip protrusions 112 extend along the axial direction of the fastening body 11.

[0026] The rubber plug 13 is inserted inside the flexible reducer 111. As one embodiment, please refer to [the relevant documentation / reference]. Figure 5 One end of the rubber plug 13 is cylindrical and integrally formed with a positioning post 131. The radius of the other end of the rubber plug 13 gradually increases and is provided with an insertion hole 132 for accommodating the guide wire 3. Both the insertion hole 132 and the positioning post 131 extend along the axial direction of the rubber plug 13.

[0027] The usage mode of the guide wire fastening structure 1 is that the flexible variable diameter 111 is pinched by hand at the end with a larger diameter, and is inserted into the fastening knob 12 until the fastening knob 12 and the external thread are in contact, one hand holds the anti-skid convex strip 112, and the other hand rotates the fastening knob 12 to make the fastening knob 12 and the fastening main body 11 threadedly connected. Then the guide wire 3 is inserted into the insertion hole 132, and then the cylindrical end of the rubber plug 13 is inserted into the flexible variable diameter 111 until the positioning column 131 is completely inserted into the positioning hole 1112. Finally, the fastening knob 12 is rotated in the reverse direction again, so that the inner wall of the fastening knob 12 extrudes the outer wall of the flexible variable diameter 111, the flexible variable diameter 111 shrinks inward, extrudes and fastens the rubber plug 13, and the rubber plug 13 extrudes and fastens the guide wire 3, and the guide wire 3 is fixed in the insertion hole 132. It can be understood that the hole diameter of the insertion hole 132 can be selected according to the diameter of the guide wire 3, that is, when different diameters of guide wires 3 need to be fixed, only the rubber plug 13 needs to be replaced.

[0028] The fixing structure 2 is used to more conveniently fix the guide wire fastening structure 1 at the corresponding position of the human body. The fixing structure 2 can only include a bandage 21, and the two ends of the bandage 21 are respectively fixed with magic tapes 211 used in cooperation. In use, the guide wire fastening structure 1 is attached to the human body, and then the guide wire fastening structure 1 is bound on the human body with the bandage 21 to prevent the guide wire fastening structure 1 from moving.

[0029] In order to further improve the stability of the connection between the guide wire fastening structure 1 and the human body and further improve the comfort of the user, the fixing structure 2 further includes an anti-skid sleeve 22. The anti-skid sleeve 22 can be made of medical silica gel, and the anti-skid sleeve 22 is internally provided with a containing hole 221 along the axial direction thereof, and the fastening knob 12 is inserted into the containing hole 221. Figure 3 For example, the anti-skid sleeve 22 can be roughly divided into a bandage connecting portion 222 and a human body connecting portion 223. The bandage connecting portion 222 is in a circular arc shape, and the bandage connecting portion 222 is provided with a limiting groove 2221 along the axial direction thereof. Please refer to Figure 4 The side surfaces of the human body connecting portion 223 are in a planar structure, and the bottom of the human body connecting portion 223 is in an arc surface slightly concave upward.

[0030] In use, the anti-skid sleeve 22 can be sleeved on the outside of the fastening knob 12, and then the guide wire 3 is installed in the aforementioned manner, which will not be described herein again. Then, the guide wire 3 is inserted into the blood vessel, the positions of the guide wire 3 and the anti-skid sleeve 22 are adjusted, the arc surface of the human body connecting portion 223 is in contact with the human body skin, and finally the fixer is fixed on the human body with the bandage 21, at this time part of the bandage 21 is clamped in the limiting groove 2221 to prevent the bandage 21 from loosening.

[0031] Obviously, the described embodiments are only part of the embodiments of the present application, not all. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the present application.
