[0031] See also Figure 1-6 The utility model provides a technical solution: a hemodialysis conversion device, comprising a dialyzer body 1 and two dialyzer tubes 2 connected to the dialyzer body 1, two mounting assemblies are fixedly connected to the side wall of the dialyzer body 1; the two mounting assemblies each comprise a mounting seat 3, two supporting blocks 4 are slidably connected to the two mounting seats 3, U-shaped blocks 5 are fixedly connected to the side walls of the two supporting blocks 4, the dialyzer tubes 2 are wound around the two U-shaped blocks 5; a locking assembly is installed between the two supporting blocks 4 and the mounting seat 3.
[0032] In this solution: the model of the dialysis machine body 1 is the Japanese DBB-26 hemodialysis machine. By winding the two dialysis tubes 2 on the corresponding two U-shaped blocks 5, the dialysis tubes 2 are arranged neatly, reducing the possibility of the medical staff accidentally pulling the dialysis tubes 2 and causing them to fall off during activities. The two U-shaped blocks 5 are fixedly connected to the two support blocks 4, and the two support blocks 4 are slidably connected to the mounting seat 3. A locking assembly is installed between the support block 4 and the mounting seat 3, so that the distance between the two U-shaped blocks 5 can be adjusted, which is convenient for winding dialysis tubes 2 of different lengths.
[0033] When the locking assembly fixes the positions of the two support blocks 4, the dialysis tube 2 is wound around the two U-shaped blocks 5. When the hemodialysis is completed and the dialysis tube 2 needs to be removed, the locking assembly is unlocked to shorten the distance between the two U-shaped blocks 5. At this time, the dialysis tube 2 is loose on the two U-shaped blocks 5, which is convenient for removing the dialysis tube 2 at one time.
[0034] In this embodiment: the locking assembly includes two racks 6 fixedly connected to the mounting base 3, and the two racks 6 are located on both sides of the support block 4; a first groove 7 is opened on the support block 4, and a first slide plate 8 is slidably connected in the first groove 7, and first protrusions 9 are fixedly connected on both sides of the first slide plate 8, and the two first protrusions 9 are meshed with the two racks 6 when they slide between the two racks 6.

During the snapping process, the inclined block 17 pushes the partition 14 to slide on the fixing seat 13, and the spring 16 is squeezed to shorten the distance between two adjacent partitions 14, thereby achieving limited clamping of the dialysis tube 2.
[0042] When taking out the dialysis tube, first rotate the cover plate 15 to release the fastening with the fixing seat 13, and the partition 14 slides on the fixing seat 13 under the elastic force of the spring 16, and increases the distance between two adjacent partitions 14, and the dialysis tube 2 can be taken out by releasing the limit clamping.

[0046] In this solution, when clamping the dialysis tube 2, first pull the moving rod 24 out of the second through hole 21, and after the cover plate 15 is snapped onto the fixing seat 13, stop pulling the moving rod 24, and insert one end of the moving rod 24 into the second through hole 21 under the tension of the tension spring 25, so that the inclined block 17 can be limited, and the dialysis tube 2 can be clamped for a long time.
[0047] In this embodiment, the opposite sides of two adjacent partitions 14 are connected with an arc-shaped plate 26 , and the concave surfaces of the two arc-shaped plates 26 face each other; and a rubber pad 27 is fixedly connected to the concave surface of the arc-shaped plate 26 .
