[0029] like Figures 1-5 As shown, the utility model provides a hemodialysis puncture needle stabilizer, comprising: a bandage 1, a binding component 2, and a protective component 3; the bandage 1 is provided with a plurality of grooves 10 that match the human arteries and veins, the spacing between adjacent grooves 10 is at least 0.5 cm, the positions of the grooves 10 coincide with the points along the direction of the human arteries and veins, and the number of grooves 10 on the arteries and veins is the same, when the doctor is giving an acupuncture, the grooves 10 can be used to give the patient an acupuncture, which is convenient for controlling the distance between the points during the acupuncture, and each time the acupuncture is performed, one needle is inserted into the artery and one needle is inserted into the vein. A sticker 11 is provided on the upper surface of the bandage 1 and on both sides of each groove 10; by sticking transparent tape on the sticker 11, the puncture needle tube connected to the tail end of the puncture needle head is fixed, thereby preventing the needle tube that moves at the tail end of the puncture needle head from being too long, causing the needle head to be easily loosened. The restraint assembly 2 includes several slide rails 20, each slidably connected to a plurality of sliders 21. The upper ends of the sliders 21 are connected to tube clamps 22 that match the external puncture needle tube. A locking assembly 23 is provided on the inner side of the sliders 21 to secure the sliders 21 to the slide rails 20. During use, the sliders 21 are used to move the tube clamps 22 horizontally, and the position of the tube clamps 22 is adjusted according to the actual situation to clamp and support the puncture needle tube. A protective assembly 3 is located above the restraint assembly 2 and is used to cover the path of the needle tube, preventing accidental damage to the needle tube in the arm.

[0030] In an embodiment, the recesses 10 are at least five pairs, which are used to leave enough time for the wound of the puncture site to recover when the puncture needle is circulated, so as to prevent inflammation, infection and other symptoms caused by secondary puncture. The side of the recess 10 is provided with a label slot 12, and the label can be inserted into the label slot 12 to mark the recess 10, so as to divide the recess 10 into groups, and each pair of recesses 10 is marked with different colors or styles to facilitate puncture recording. The two ends of the bandage 1 are respectively connected with a magic tape hook surface 13 and a fuzzy surface 14. The bandage 1 is bound on the patient's arm through the magic tape hook surface 13 and the fuzzy surface 14, so that the recess 10 is as close as possible to the direction of the artery and vein on the patient's arm.

[0031] In an embodiment, the slide rail 20 is an arc-shaped elastic structure, which is convenient to be combined with the bandage 1 and the patient's arm, and the slide rail 20 makes the puncture needle tube as close as possible to the patient's arm through the slide block 21 and the pipe clamp 22. The pipe clamp 22 is opened upward.

[0032] In an embodiment, the locking assembly 23 includes a latch 230, the upper end of the latch 230 is connected with a pressing block 231, the lower end of the latch 230 is connected with a spring 232, the upper end of the slide block 21 is provided with a pressing groove 210 matched with the pressing block 231, the inside of the slide block 21 is provided with a movable groove 211 matched with the latch 230, and the two sides of the slide rail 20 are provided with a tooth groove 200 matched with the latch 230. In use, the pressing block 231 is pressed to drive the latch 230 to descend, and the spring 232 is compressed, so that the latch 230 is separated from the tooth groove 200, thereby canceling the limitation of the slide block 21 and the slide rail 20. Then, the slide block 21 is dragged through the pressing block 231, so that the slide block 21 moves to a designated position on the slide rail 20. Then, the pressing block 231 is released, and the latch 230 and the pressing block 231 are reset under the action of the spring 232, so that the latch 230 is combined with the tooth groove 200 again, thereby fixing the slide block 21.

[0033] In an embodiment, the protection assembly 3 includes a cover plate 30, one end of the cover plate 30 is rotationally connected with the bandage 1, the other end of the cover plate 30 is provided with a buckle 31, and the outer surface of the bandage 1 is provided with a clamping groove matched with the buckle 31. The cover plate 30 is covered on the puncture needle tube by rotating the cover plate 30, and then the buckle 31 is inserted into the clamping groove to fix the cover plate 30, thereby enhancing the protection effect of the puncture needle tube.

[0034] In an embodiment, the cover plate 30 is provided in a U-shaped structure, which is convenient to store the puncture needle tube. The two ends of the cover plate 30 are connected with soft pads 32 on the surface of the bandage 1, and the puncture needle tube is clamped by the soft pads 32, thereby further enhancing the stability of the puncture needle tube.

[0035] The specific use process of the utility model is as follows: align the groove 10 on the bandage 1 with the direction of the veins on the patient's arm, tie the bandage 1 to the patient's arm, use the puncture needle through the groove 10 to puncture the artery and vein respectively, and repeat the cycle. After the needles are inserted, stick them on the adhesive plate 11 with tape, fix the needle tube at the tail end of the puncture needle head, and move the slider 21 according to the actual needle insertion position. The slider 21 drives the tube clamp 22 to move to the specified position and clamps the puncture needle tube to complete the operation. At the same time, a cover plate 30 is also provided. After the puncture needle tube is fixed, the cover plate 30 is flipped over to cover the puncture needle tube on the patient's arm.

[0036] In summary, the utility model discloses a hemodialysis puncture needle stabilizer, which pairs the grooves 10 on the artery and vein by setting a groove 10 that conforms to the direction of the veins in the human arm, so as to facilitate hemodialysis through the designated puncture point and avoid repeated punctures with the puncture points being close, causing damage to the fistula and adjacent blood vessels. The movable tube clamp 22 facilitates the adjustment of the position of the tube clamp 22 according to the actual puncture needle tube, and facilitates the support of the puncture needle tube. At the same time, a cover plate 30 is also provided. After the puncture needle tube is fixed, the cover plate 30 is flipped over to cover the puncture needle tube on the patient's arm, thereby playing a role in strengthening protection and avoiding the problem of the puncture needle tube falling off due to collision and scratching.

[0037] Therefore, the utility model effectively overcomes various shortcomings of the prior art and has high industrial utilization value.
