[0045] Embodiment 2

[0046] Refer to Figure 5 As shown, this embodiment provides a bedside fixing device for the extracorporeal circulation pipeline during hemodialysis treatment, including a snap ring elastic steel sheet 1 and a buckle 2; the snap ring elastic steel sheet 1 includes a first side 11 and a second side 12. In the unfolded state, the snap ring elastic steel sheet 1 protrudes from the first side 11 to the second side 12 to form an arch, and at this time, the snap ring extends linearly along the length direction. When the second side 12 of the snap ring elastic steel sheet 1 is pressed, the arch is damaged, and the snap ring elastic steel sheet 1 curls towards the second side 12 into a ring shape, so that the snap ring elastic steel sheet 1 can be fixed on the guardrail beside the nursing bed. The buckle 2 is connected to the first side 11 of the snap ring elastic steel sheet 1, and when the snap ring curls into a ring shape, the buckle 2 is located on the outside. A clamping groove 21 for the pipeline to pass through is provided on the buckle 2, and the pipeline is clamped in the clamping groove 21 to fix the pipeline.

[0047] For the bedside fixing device for the extracorporeal circulation pipeline during hemodialysis treatment provided by this embodiment, the pipeline is clamped on the buckle 2. Pressing the second side 12 of the snap ring elastic steel sheet 1 can curl the snap ring elastic steel sheet 1 into a ring shape and fix it on the guardrail beside the nursing bed. When adjusting the posture and fixing position of the pipeline, unfold the snap ring elastic steel sheet 1 and then move it to the corresponding position. The adjustment process is convenient and can be recycled, reducing resource waste.

[0048] Specifically, the clamping groove 21 includes an opening part 26 and a receiving part 27. The buckle 2 includes a first surface 22, a second surface 23 and a third surface 24, wherein the first surface 22 is adjacent to the second surface 23 and the third surface 24 respectively, and the second surface 23 is opposite to the third surface 24. The opening part 26 is located on the first surface 22, and the receiving part 27 extends from the second surface 23 to the third surface 24 and penetrates through the buckle 2. When fixing the pipeline, the pipeline is clamped into the receiving part 27 from the opening part 26.

[0049] Specifically, the width of the opening portion 26 is smaller than the diameter of the pipeline; the cross-section of the accommodating portion 27 is arc-shaped, and the diameter of the accommodating portion 27 is not smaller than the diameter of the pipeline. This ensures that the pipeline is stably clamped in the clamping groove 21.

[0050] Specifically, a transition surface 28 is formed between the opening portion 26 and the accommodating portion 27, and the transition surface 28 is arc-shaped. This facilitates the snap 2 to enter the accommodating portion 27 from the opening portion 26 and avoids sharp structures from damaging the pipeline.

[0051] Specifically, a protective cover 3 is wrapped on the surface of the snap ring elastic steel sheet 1, and the protective cover 3 can be made of flexible materials such as silicone, so that the protective cover 3 can deform with the snap ring elastic steel sheet 1. By providing the protective cover 3, the snap ring elastic steel sheet 1 can be prevented from cutting medical staff during use.

[0052] Specifically, in this embodiment, the snap 2 is rotatably connected to the first side 11 of the snap ring elastic steel sheet 1 through a connecting member 4. By rotating the snap 2, the angle of the clamping groove 21 can be adjusted, thereby enabling the attitude of the pipeline to be adjusted.

[0053] Specifically, referring to Figure 6 As shown, a first round hole 13 is provided on the snap ring elastic steel sheet 1, an installation space 201 is provided inside the snap 2, and a second round hole 202 communicating with the installation space 201 is provided on the fourth surface 25 of the snap 2 close to the snap ring elastic steel sheet 1; the connecting member 4 includes a connecting rod and a nut 43, the connecting rod includes a threaded rod body 41 and a pressing head 42, the pressing head 42 is placed in the installation space 201, the threaded rod body 41 is connected to the pressing head 42 and sequentially passes through the second round hole 202 and the first round hole 13 and then is connected to the nut 43. When the nut 43 is loosened, the snap 2 can rotate relative to the connecting rod, thereby adjusting the angle of the clamping groove 21. When the nut 43 is tightened, the snap 2 and the snap ring elastic steel sheet 1 are pressed, thereby being able to relatively fix the snap 2 and the snap ring elastic steel sheet 1 and maintain the angle of the clamping groove 21.

[0054] Specifically, the pressing head 42 is non-circular, and a limiting groove 203 engaged with the pressing head 42 is provided on the inner wall of the installation space 201 facing the snap ring elastic steel sheet 1. After the pressing head 42 is engaged with the limiting groove 203, the rotation of the pressing head 42 is restricted. When the nut 43 needs to be turned, the connecting rod is pulled toward the second side 12 to engage the pressing head 42 with the limiting groove 203, restricting the rotation of the connecting rod, so that the nut 43 can be turned more conveniently. When the angle of the clamping groove 21 needs to be adjusted, the nut 43 is loosened to disengage the pressing head 42 from the limiting groove 203, so that the snap 2 can be rotated.

[0055] Specifically, the buckle 2 includes a first part 204 and a second part 205. The first part 204 is provided with a first groove, and the second part 205 is provided with a second groove. The first part 204 and the second part 205 are welded so that the first groove and the second groove are combined into an installation space 201. When preparing the buckle 2, the corresponding grooves are first prepared on the first part 204 and the second part 205 respectively. After passing the connecting rod through the second round hole 202, the first part 204 and the second part 205 are welded. Specifically, the buckle 2 can be prepared by using plastic materials.

[0056] Usage process: First, adjust the angle of the card slot 21 according to the attitude requirement of the pipeline; then press the second side 12 of the snap ring elastic steel sheet 1 to curl it into a ring and fix it at a suitable position on the railing beside the nursing bed, and then place the pipeline in the card slot 21. When it is necessary to adjust the position of the pipeline, unfold the snap ring elastic steel sheet 1 and move it to a suitable position, and then press the second side 12 of the snap ring elastic steel sheet 1 again to fix the snap ring elastic steel sheet 1.

[0057] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the various technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.
