[0026] Next, in combination with the instruction drawings of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0027] Refer to Figure 1 - Figure 5, An embodiment provided by the present utility model: A multifunctional venous catheter clip, including a plastic splint 1, a first fixing strip 2, and a catheter clamping block 15. An insertion hole 3 is provided on the outer wall of the plastic splint 1, and the outer wall of the catheter clamping block 15 is fixedly connected to the inner wall of the insertion hole 3. An adjustment groove 4 is provided on the outer wall of the plastic splint 1, a U-shaped groove 5 is provided inside the plastic splint 1, a limiting groove 6 is provided inside the plastic splint 1, a first clamping groove 7 is provided inside the plastic splint 1, a second clamping groove 8 is provided inside the plastic splint 1. The outer wall of the first fixing strip 2 is fixedly connected to the inner wall of the U-shaped groove 5. A first clamping tooth 9 is fixedly connected to the outer wall of the first fixing strip 2. A second clamping tooth 10 is slidably connected to the outer wall of the first clamping tooth 9. A second fixing strip 11 is fixedly connected to the outer wall of the second clamping tooth 10. A limiting post 12 is fixedly connected to the outer wall of the second fixing strip 11. The outer wall of the limiting post 12 is slidably connected to the inner wall of the limiting groove 6. A fixing component is provided on the outer wall of the second fixing strip 11, and the fixing component is used to fix the second fixing strip 11; The fixing component includes a first plastic bead 13 and a second plastic bead 14. The outer wall of the first plastic bead 13 is fixedly connected to the outer wall of the second fixing strip 11. The outer wall of the second plastic bead 14 is fixedly connected to the outer wall of the second fixing strip 11. The outer wall of the first plastic bead 13 is slidably connected to the inner wall of the first clamping groove 7. The outer wall of the first plastic bead 13 is slidably connected to the inner wall of the second clamping groove 8. The outer wall of the second plastic bead 14 is slidably connected to the inner wall of the second clamping groove 8;

[0028] Specifically, the limiting groove 6 is used to limit the second fixing strip 11. During the downward movement of the second fixing strip 11, the second fixing strip 11 will drive the limiting post 12 to slide on the inner wall of the limiting groove 6, which can prevent the second fixing strip 11 from slipping out. Since the plastic splint 1, the first plastic bead 13, and the second plastic bead 14 are all made of plastic material and have certain elastic characteristics, it can ensure the convenient movement and stable fixation of the second fixing strip 11, and it can withstand multiple uses without failure or deformation. When the second fixing strip 11 is not pressed, the first plastic bead 13 fixedly connected to the outer wall of the second fixing strip 11 fits with the inner wall of the first clamping groove 7, and the second plastic bead 14 fixedly connected to the outer wall of the second fixing strip 11 fits with the inner wall of the second clamping groove 8. When pressing the second fixing strip 11 downward, the downward movement of the second fixing strip 11 causes the first plastic bead 13 fixedly connected to the outer wall of the second fixing strip 11 to slide out from the outer wall of the first clamping groove 7 and then slide to the inner wall of the second clamping groove 8, thereby fixing the second fixing strip 11 in a certain position and keeping it unchanged.

[0029] Referring to Figure 4 - Figure 7 , a rectangular groove 16 is provided on the outer wall of the plastic splint 1, a first rotating column 17 is fixedly connected inside the plastic splint 1, and an L-shaped block 25 is fixedly connected to the outer wall of the plastic splint 1;

[0030] Specifically, the plastic splint 1 can fix the first rotating column 17 and the L-shaped block 25.

[0031] Referring to Figure 1 、 Figure 6 and Figure 7 , a support shell plate 18 is rotatably connected to the outer wall of the first rotating column 17. A first magnetic sheet 19 is fixedly connected to the inner wall of the support shell plate 18. A placement groove 20 is formed in the inner wall of the support shell plate 18. A second rotating column 21 is fixedly connected to the inner wall of the support shell plate 18. A support plate 22 is rotatably connected to the outer wall of the second rotating column 21. A second magnetic sheet 23 is fixedly connected to the outer wall of the support plate 22. The outer wall of the second magnetic sheet 23 is attached to the outer wall of the first magnetic sheet 19. A third rotating column 24 is fixedly connected to the inside of the support plate 22. The outer wall of the third rotating column 24 is slidably connected to the inner wall of the placement groove 20. The outer wall of the third rotating column 24 is slidably connected to the outer wall of the L-shaped block 25. A friction strip 26 is slidably connected to the outer wall of the support shell plate 18. The outer wall of the friction strip 26 is fixedly connected to the inner wall of the rectangular groove 16.

[0032] Specifically, when the plastic splint 1 is not supported, the third rotating column 24 fixedly connected to the inside of the support plate 22 slides on the inner wall of the placement groove 20. Here, the placement groove 20 can place the third rotating column 24, providing a placement space for the third rotating column 24. At the same time, the inner wall of the support shell plate 18 also provides a placement space for the support plate 22, facilitating its folding and storage. The second magnetic sheet 23 fixedly connected to the outer wall of the support plate 22 and the first magnetic sheet 19 fixedly connected to the inner wall of the support shell plate 18 are used to keep the inner wall of the support plate 22 and the support shell plate 18 in a fitting state. When the support shell plate 18 is rotated, the support shell plate 18 will slide on the outer wall of the friction strip 26. The friction strip 26 is fixedly connected to the inner wall of the rectangular groove 16 to increase the friction force on the support shell plate 18 and play a role in fixing the support shell plate 18, ensuring that the support shell plate 18 will not slide out of the inner wall of the rectangular groove 16 when the plastic splint 1 is not supported.

[0033] Working principle: When using this intravenous catheter clip, pass the disinfected catheter through the introduction hole 3. After the catheter passes through, it can contact the catheter clamping block 15. At this time, the catheter clamping block 15 can support the catheter and adjust the flow rate. When it is necessary to adjust the flow rate of the catheter flow rate for the second time, slide the catheter along the outer wall of the second fixing strip 11. When it slides to the required position, press the second fixing strip 11 to cause the second fixing strip 11 to drive the second tooth 10 to slide on the outer wall of the first tooth 9 and move downward. During the movement of the second fixing strip 11, the limiting column 12 fixedly connected to the outer wall of the second fixing strip 11 will slide on the inner wall of the limiting groove 6. At the same time, the downward movement of the second fixing strip 11 causes the first plastic bead 13 fixedly connected to the outer wall of the second fixing strip 11 to slide out from the outer wall of the first card slot 7 and then slide into the inner wall of the second card slot 8, so that the second fixing strip 11 can be fixed in a certain position and remain unchanged. At this time, the second fixing strip 11 still maintains the flow control of the catheter. As the second fixing strip 11 drives the second tooth 10 to move downward, the first tooth 9 contacts the catheter. Due to the tooth shape design of the first tooth 9, the catheter can be prevented from sliding out of the outer wall of the second fixing strip 11, preventing the catheter from sliding when the flow rate is adjusted to an appropriate value under external force, avoiding inconvenience to medical staff and adverse effects on patients. Rotate the support shell plate 18 to cause the support shell plate 18 to rotate on the outer wall of the first rotating column 17. When the support shell plate 18 is adjusted to the support position, rotate the support plate 22 to separate the second magnetic sheet 23 from the first magnetic sheet 19, so that the support plate 22 rotates on the outer wall of the second rotating column 21. Rotate the support plate 22 to cause the support plate 22 to drive the third rotating column 24 to slide to the outer wall of the side of the L-shaped block 25 close to the plastic splint 1, and complete the support of the plastic splint 1. The plastic splint 1, the support plate 22 and the support shell plate 18 form a triangular support shape, with strong stability, which can ensure that the catheter does not move and is convenient for medical staff to operate.

[0034] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
