Technical Field

[0001] This utility model relates to the field of medical assistive device technology, and in particular to an arteriovenous fistula clip. Background Technology

[0002] Arteriovenous fistulas (AVFs) are the "lifeline" for patients undergoing maintenance hemodialysis, and proper fistula care is crucial for treatment outcomes and quality of life. AVF clips, as an important auxiliary tool, play a key role in protecting the fistula, preventing backflow of blood, and mitigating accidental bleeding. AVF clips are an essential auxiliary tool for hemodialysis patients, playing a vital role in protecting the fistula, improving treatment effectiveness, and enhancing quality of life.

[0003] However, existing arteriovenous fistula clips have the following disadvantages:

[0004] (1) Existing arteriovenous fistula clips may require complex tools or cumbersome operating procedures, making it difficult to quickly clamp the device.

[0005] (2) Existing arteriovenous fistula clips usually use screws, glue and other tools or materials to fix the hemostatic cotton, which can easily lead to more time spent installing and replacing the hemostatic cotton.

[0006] Therefore, this utility model provides an arteriovenous fistula clip. Utility Model Content

[0016] (III) Beneficial Effects

[0017] This utility model provides an arteriovenous fistula clip, which has the following beneficial effects:

[0018] 1. This arteriovenous fistula clamp, through the arrangement of a sliding block, spring, locking block, arc-shaped block, and connecting rod, allows for easy use. First, pushing the push block moves the connecting rod, which in turn moves the locking block via the sliding block. Simultaneously, compressing the spring separates the locking block from the ratchet of the arc-shaped block. Once separated, the upper clamp handle can be easily rotated to hold the puncture point. When the device is adjusted to the appropriate position, releasing the push block allows the locking block to reset under the action of the spring, thus securing the device and ensuring rapid and stable clamping of the puncture point.

[0019] 2. This arteriovenous fistula clip, through the arrangement of a T-shaped slider, mounting plate, A magnetic block, and B magnetic block, allows for easy installation of hemostatic cotton. First, the T-shaped slider is aligned with the T-shaped groove and moved, causing the mounting plate to move. This moves the B magnetic block on the mounting plate. When the B magnetic block comes into contact with the A magnetic block, the hemostatic cotton on the mounting plate is fixed to the upper clip under the action of the A and B magnetic blocks. This allows medical staff to quickly complete the installation of the hemostatic cotton, saving valuable time. Attached Figure Description

[0026] Please see Figures 1 to 4This utility model provides a technical solution: an arteriovenous fistula clip, including a lower clip 1, a lower clip handle 2 fixedly connected to one end of the lower clip 1, a cavity opened inside the lower clip handle 2, a sliding block 3 slidably connected to the inner wall of the cavity, a spring 4 connected between one side of the sliding block 3 and the inner wall of the cavity, a connecting rod 7 fixedly connected to the top of the sliding block 3, a locking block 5 fixedly connected to the other side of the sliding block 3, an arc-shaped block 6 locking one side of the locking block 5, a plurality of ratchet teeth adapted to the locking block 5 opened on one side of the arc-shaped block 6, and an upper clip handle 1 fixedly connected to one end of the arc-shaped block 6. 5. Through the arrangement of sliding block 3, spring 4, locking block 5, arc-shaped block 6, and connecting rod 7, when using the device, first push the push block 17 to move the connecting rod 7, so that the connecting rod 7 moves the locking block 5 through the sliding block 3. At the same time, the spring 4 is compressed, causing the locking block 5 to separate from the ratchet of the arc-shaped block 6. After the locking block 5 separates from the ratchet of the arc-shaped block 6, the upper clamp handle 15 can be easily rotated to press the puncture point. When the device is adjusted to the appropriate position, release the push block 17. Under the action of the spring 4, the locking block 5 resets, thus completing the fixation of the device and ensuring that the device can quickly... The puncture point is stably clamped. A rotating block 8 is fixedly connected to one end of the upper clamp handle 15. One end of the rotating block 8 is rotatably connected to one end of the lower clamp 1, and the other end of the rotating block 8 is fixedly connected to the upper clamp 9. A T-shaped groove is formed on one side of the upper clamp 9, and a T-shaped slider 10 is slidably connected inside the T-shaped groove. A mounting plate 11 is fixedly connected to the bottom of the T-shaped slider 10. Circular grooves are formed on the bottom of the upper clamp 9 and the top of the mounting plate 11. Magnets A 12 and B 13 are respectively installed inside the circular grooves of the upper clamp 9 and the mounting plate 11. Magnets A 12 and B 13 are compatible and installed... The bottom of the plate 11 is equipped with hemostatic cotton 14. With the arrangement of T-shaped slider 10, mounting plate 11, A magnetic block 12 and B magnetic block 13, when installing hemostatic cotton 14, first align the T-shaped slider 10 with the T-shaped groove and move it, which drives the mounting plate 11 to move, so that the B magnetic block 13 on the mounting plate 11 moves. When the B magnetic block 13 moves to contact the A magnetic block 12, under the action of the A magnetic block 12 and the B magnetic block 13, the hemostatic cotton 14 on the mounting plate 11 is fixed to the upper clamping plate 9, so that medical staff can quickly complete the installation of hemostatic cotton 14, saving valuable time.

[0027] Plastic sleeves 16 are fixedly fitted onto the surfaces of both the lower clamp handle 2 and the upper clamp handle 15. The plastic sleeves 16 improve the stability of the device for medical staff to hold. The surface of the plastic sleeves 16 is provided with anti-slip texture.

[0028] A push block 17 is fixedly connected to one side of the connecting rod 7. The push block 17 facilitates medical staff to push the connecting rod 7. A groove is provided on the top of the push block 17.

[0029] An anti-slip pad 18 is fixedly connected to the surface of the lower splint 1. The anti-slip pad 18 improves the patient's comfort. The anti-slip pad 18 is made of sponge material.

[0030] A stiffening plate 19 is fixedly connected to the surface of the upper clamping plate 9. The stiffening plate 19 ensures the strength of the device. One end of the stiffening plate 19 is fixedly connected to one side of the rotating block 8.

[0031] The bottom of the sliding block 3 is fixedly connected to the limiting block 20. The setting of the limiting block 20 ensures the stability of the sliding block 3 when it moves. The inner bottom wall of the cavity is provided with a sliding groove that matches the limiting block 20. The limiting block 20 is movably connected to the inside of the sliding groove.

[0032] In this invention, the working steps of the device are as follows:

[0033] First step: First, push the push block 17 to move the connecting rod 7, so that the connecting rod 7 moves the locking block 5 through the sliding block 3. At the same time, compress the spring 4 to separate the locking block 5 from the ratchet of the arc-shaped block 6. After the locking block 5 separates from the ratchet of the arc-shaped block 6, the upper clamping plate handle 15 can be easily rotated to press the puncture point. When the device is adjusted to the appropriate position, release the push block 17. Under the action of the spring 4, the locking block 5 is reset, thereby completing the fixation of the device and ensuring that the device quickly and stably clamps the puncture point.

[0034] The second step: Next, align the T-shaped slider 10 with the T-shaped groove and move it, which will move the mounting plate 11. This will cause the B magnetic block 13 on the mounting plate 11 to move. When the B magnetic block 13 moves to contact the A magnetic block 12, the hemostatic cotton 14 on the mounting plate 11 will be fixed to the upper clamp 9 under the action of the A magnetic block 12 and the B magnetic block 13. This allows medical staff to quickly complete the installation of the hemostatic cotton 14, saving valuable time.
