[0031] During specific use, the dialysis needle tip 16 is first fixed by the second fixing mechanism, and then the dialysis needle handle 15 is fixed by the first fixing mechanism. Then, the dialysis tubing 14 is fixed by the attachment body. The utility model realizes the three fixing steps of the dialysis tubing 14 and the dialysis needle through an integrated fixing device, and there is no need to fix them separately with tape, thereby improving the integrity of the fixation of the dialysis needle and the dialysis tubing 14, thereby further reducing the risk of needle removal.

[0032] In some embodiments, Figures 1 to 3 As shown, the attachment body includes a patch 1 that is symmetrically arranged on the left and right, and the two patches 1 are integrally connected by a pipeline fixing patch 2. The length of the pipeline fixing patch 2 is greater than or equal to the outer circumference of the dialysis pipeline 14, and the inner side surfaces of the patch 1 and the pipeline fixing patch 2 are provided with a first adhesive layer.

[0033] During specific use, when fixing the dialysis tubing 14, first place the dialysis tubing 14 between the two patches 1, so that the tubing fixing patch 2 is wrapped around and attached to the outside of the dialysis tubing 14, and then stick the patch 1 to the patient's skin surface, thereby fixing the dialysis tubing 14 by the Ω-type fixing method (the cross-sectional shape of the tubing fixing patch 2 is Ω when fixed).

[0034] In some embodiments, Figures 1 to 3 As shown, the first fixing mechanism includes a first horizontal sticker 3, one side of the first horizontal sticker 3 is integrally connected to one of the patches 1, the other side of the first horizontal sticker 3 is integrally formed with a second horizontal sticker 4, and the first horizontal sticker 3 and the second horizontal sticker 4 are arranged alternately; a first connecting area 5 between the first horizontal sticker 3 and the second horizontal sticker 4 is arranged below the pipeline fixing sticker 2; and a second adhesive layer is provided on the outer side surfaces of the first horizontal sticker 3 and the second horizontal sticker 4.

Figure 1 As shown, one end of the strip sticker 6 is flipped to the other side in a direction away from the pipeline fixing sticker 2 for pasting, and the same operation is performed on the other end of the strip sticker 6, so that the strip sticker 6 fixes the dialysis needle end 16 by a V-shaped fixing method.

[0038] In some embodiments, Figures 1 to 3 As shown, the two dressings 1 are provided with a groove hole 8 on the side connected to the pipeline fixing patch 2 for the dialysis needle handle to pass through.

[0039] During specific use, when the dialysis needle handle 15 passes through the gap between the patch 1 and the first horizontal patch 3 and is inserted between the two patches 1, the spiral protrusion on the dialysis needle handle 15 can pass through both sides of the device.

[0051] The working principle of this device:

[0052] First, the dialysis needle handle 15 is inserted between the two dressings 1 through the gap between the dressing 1 and the first horizontal patch 3, so that the dialysis needle handle 15 is located on the second adhesive layer, and then the dialysis needle tip 16 is fixed by the second fixing mechanism. Figure 1 As shown, one end of the strip sticker 6 is turned over to the other side in a direction away from the pipeline fixing sticker 2 for pasting, and the other end of the strip sticker 6 is also subjected to the same operation, so that the strip sticker 6 fixes the dialysis needle end 16 by a V-shaped fixing method.

[0053] Then, the dialysis needle handle 15 is fixed by the first fixing mechanism, such as Figure 1 As shown, the first horizontal sticker 3 and the second horizontal sticker 4 are turned over in opposite directions, and then the second adhesive layers of the first horizontal sticker 3 and the second horizontal sticker 4 are adhered to the patient's skin, so as to achieve winding and fixing of the needle handle of the dialysis needle by the α-type fixing method;

[0054] Subsequently, the dialysis tubing 14 is arranged between the two dressings 1, so that the tubing fixing patch 2 is wrapped around and attached to the outside of the dialysis tubing 14, and then the dressing 1 is attached to the skin surface of the patient, thereby fixing the dialysis tubing 14 by an Ω-type fixing method (the cross-sectional shape of the tubing fixing patch 2 during fixing is Ω);

[0055] Finally, the wrist fixing belt 9 is wrapped around the patient's arm 17 and fixed by gluing.

[0056] The utility model realizes the three fixing steps of the dialysis tubing 14 and the dialysis needle through an integrated fixing device, and does not need to be fixed separately by adhesive tape, thereby improving the integrity of the fixation of the dialysis needle and the dialysis tubing 14, thereby further reducing the risk of the needle falling off.

[0057] The above-mentioned embodiments only express the specific implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the protection scope of the present application. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the technical solution concept of the present application, and these all belong to the protection scope of the present application.
