[0032] See also Figure 1-3 The utility model provides a technical solution: a dialysis tube limiting clamping device, comprising a mounting seat 11, a plurality of vertical plates 12 are slidably connected to the mounting seat 11, a channel for the dialysis tube to pass through is formed between two adjacent vertical plates 12, a cover plate 13 is arranged on the mounting seat 11, the cover plate 13 is hinged to one side of the mounting seat 11, and can rotate around the intersection point as an axis; a linkage component is arranged between the cover plate 13 and the vertical plate 12, and the cover plate 13 can drive the two adjacent vertical plates 12 to move closer together through the linkage component during the rotation process; a strap 51 for wrapping around the wrist is connected to the mounting seat 11.
[0033] In this solution, the mounting seat 11 includes a mounting seat horizontal plate and a mounting seat vertical plate, and the cover plate 13 is connected to the mounting seat vertical plate by a hinge. There are three vertical plates 12, and the mounting seat vertical plate is parallel to the three vertical plates 12, and the three vertical plates 12 are all slidably connected to the mounting seat horizontal plate.
[0034] When clamping the dialysis tube, first wrap the strap 51 around the wrist, and then pass the two dialysis tubes through the gaps between the three adjacent vertical plates 12, and then rotate the cover plate 13 to snap onto the mounting seat 11. During the snapping process, the linkage assembly drives the vertical plate 12 to slide on the mounting seat 11, and shortens the distance between two adjacent vertical plates 12, so as to achieve the limited clamping of the dialysis tube. Compared with the prior art method of fixing the dialysis tube on the wrist with medical tape, it avoids the problem that multiple dialysis tubes are fixed on the wrist in parallel, and the dialysis tubes will be pulled when the hand moves, and the gaps between adjacent dialysis tubes will increase, resulting in the problem of the medical tape used to fix the dialysis tube falling off.
[0035] When taking out the dialysis tube, first rotate the cover plate 13 to release the buckle with the mounting seat 11, and the linkage assembly drives the vertical plate 12 to slide on the mounting seat 11 and increase the distance between two adjacent vertical plates 12, so as to release the limit clamping of the dialysis tube and take out the dialysis tube.
[0036] In this embodiment: the linkage assembly includes a spring 22 arranged between two adjacent vertical plates 12 and an inclined block 14 for pushing the vertical plate 12 to move toward one end, and the two ends of the spring 22 are respectively against the two adjacent vertical plates 12 in a freely extended state; the inclined block 14 is fixedly connected to the cover plate 13, and the inclined surface of the inclined block 14 faces the vertical plate 12.
[0037] When clamping the dialysis tube, first wrap the strap 51 around the wrist, and then pass the two dialysis tubes through the gaps between the three adjacent vertical plates 12, and then rotate the cover plate 13 to buckle on the mounting seat 11. During the buckling process, the inclined block 14 pushes the vertical plate 12 to slide on the mounting seat 11, and the spring 22 is squeezed to shorten the distance between the two adjacent vertical plates 12, thereby achieving limited clamping of the dialysis tube.
[0038] When taking out the dialysis tube, first rotate the cover plate 13 to release the buckle with the mounting seat 11, and the vertical plate 12 slides on the mounting seat 11 under the elastic force of the spring 22, and increases the distance between two adjacent vertical plates 12, so that the dialysis tube can be taken out by releasing the limit clamping.
[0039] In this embodiment: a mounting seat groove 111 is opened on the mounting seat 11, and a vertical plate through hole 121 is opened on the vertical plate 12; a sliding rod 21 is fixedly connected in the mounting seat groove 111, the sliding rod 21 passes through the vertical plate through hole 121, the vertical plate 12 is slidably connected to the sliding rod 21, and the spring 22 is sleeved on the sliding rod 21.
[0040] By arranging the sliding rod 21 in the mounting seat groove 111 and passing the sliding rod 21 through the vertical plate through hole 121, the spring 22 is sleeved on the sliding rod 21. When the spring 22 is deformed, the spring 22 and the vertical plate 12 both move along the length direction of the sliding rod 21.
[0041] In this embodiment: the inclined block 14 is provided with an inclined block hole 141 , the mounting seat is fixedly connected with a connecting block 31 , the connecting block 31 is provided with a connecting block through hole 311 , and a moving rod 32 is slidably connected in the connecting block through hole 311 .
[0042] When clamping the dialysis tube, the cover plate 13 is rotated to engage with the mounting seat 11, and the moving rod 32 is inserted into the connecting block through hole 311 and the inclined block hole 141 in sequence, so that the inclined block 14 can be limited and the dialysis tube can be clamped for a long time.
[0043] When taking out the dialysis tube, the moving rod 32 is pulled out of the inclined block hole 141 to release the limit of the inclined block 14, and the cover plate 13 is rotated to release the engagement with the mounting seat 11. The vertical plate 12 slides under the elastic force of the spring 22, and the gap between adjacent vertical plates 12 increases. The limit clamping of the dialysis tube is released and the dialysis tube can be taken out.
[0044] In this embodiment: a tension spring 33 is sleeved on the moving rod 32, and the two ends of the tension spring 33 are fixedly connected to the end surface of the moving rod 32 and the side wall of the connecting block 31 respectively. When the tension spring 33 is in a naturally expanded state, one end of the moving rod 32 remains through and protrudes out of the through hole 311 of the connecting block.
[0045] When clamping the dialysis tube, first pull the moving rod 32 out of the mounting seat groove 111, and after the cover plate 13 is snapped onto the mounting seat 11, stop pulling the moving rod 32. Under the tension of the tension spring 33, one end of the moving rod 32 is inserted into the inclined block hole 141, thereby realizing the limiting of the inclined block 14 and achieving long-term limiting clamping of the dialysis tube.
[0046] When taking out the dialysis tube, first pull the moving rod 32 out of the inclined block hole 141 to release the limit of the inclined block 14, rotate the cover plate 13 to release the engagement with the mounting seat 11, and the vertical plate 12 slides under the elastic force of the spring 22.

[0047] In this embodiment, one end of the moving rod 32 inserted into the inclined block hole 141 is provided with a moving rod inclined surface 321 , and the moving rod inclined surface 321 faces the inclined block 14 .
[0048] When clamping the dialysis tube, when the cover plate 13 is buckled on the mounting seat 11, the inclined surface 321 of the moving rod is subjected to the pressure of the inclined block 14, and the moving rod 32 withdraws from the mounting seat groove 111. After the cover plate 13 is buckled on the mounting seat 11, one end of the moving rod 32 is inserted into the inclined block hole 141 under the tension of the tension spring 33, thereby realizing the limiting of the inclined block 14 and realizing the long-term limiting clamping of the dialysis tube.
[0049] In this embodiment, the opposite sides of two adjacent vertical plates 12 are connected with arc-shaped plates 41 , and the concave surfaces of the two arc-shaped plates 41 face each other.
[0050] In this solution: the concave surface of the arc-shaped plate 41 matches the outer contour of the dialysis tube.
[0051] By arranging arc-shaped plates 41 on opposite sides of two adjacent vertical plates 12 to clamp the dialysis tube, the gap between the dialysis tube and the clamping device can be reduced, and the clamping effect is better.
[0052] In this embodiment, a rubber pad 42 is fixedly connected to the concave surface of the arc plate 41 .
[0053] By arranging rubber pads 42 on the concave surfaces of the two arc-shaped plates 41 to clamp the dialysis tube, the gap between the dialysis tube and the position limiting clamping device can be further reduced, and the position limiting clamping effect is better.
[0054] In this embodiment: one end of the strap 51 is fixedly connected to a pull ring 52 , and the other end is provided with a Velcro fleece surface 53 and a Velcro hook surface 54 , and the Velcro fleece surface 53 and the Velcro hook surface 54 are fixedly connected to the surface of the strap 51 .
[0055] When installing the clamping device, first wrap the strap 51 around the wrist, then pass one end of the strap 51 with the Velcro fleece surface 53 and the Velcro hook surface 54 through the pull ring 52, and stick the Velcro hook surface 54 to the Velcro fleece surface 53, so that the limiting clamping device is more firmly fixed on the wrist.
[0056] When removing the clamping device, first pull the Velcro hook surface 54 away from the Velcro fleece surface 53, and then take out the end of the strap 51 provided with the Velcro fleece surface 53 and the Velcro hook surface 54 from the pull ring 52, and the position limiting clamping device can be removed.
[0057] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
