[0020] Embodiment one, by Figure 1 , Figure 2 and Figure 7The present application comprises a dialysis instrument body 1, a support shell 2 is arranged below the dialysis instrument body 1, the support shell 2 is a cavity structure with an open bottom, an anti-skid base 4 is arranged below the support shell 2, a plurality of universal wheels 60 are fixedly installed on the outer wall of the support shell 2, the support shell 2 is rotationally connected with a rotating shaft 5, the top end of the rotating shaft 5 is installed with a shaking structure for driving the dialysis instrument body 1 to shake horizontally, at least two first lead screws 6 are rotationally connected in the support shell 2, a threaded sleeve 7 is arranged outside the first lead screw 6, the bottom end of the threaded sleeve 7 is rotationally connected with the anti-skid base 4, the support shell 2 is installed with a rotation-stopping adjusting structure matched with the threaded sleeve 7, the threaded sleeve 7 is installed with a damping transmission assembly matched with the rotating shaft 5, and the support shell 2 is installed with a driving mechanism for driving the first lead screw 6 to rotate.

[0021] In the second embodiment, on the basis of the first embodiment, Figure 2 , Figure 5 , Figure 6 and Figure 7The anti-rotation adjustment structure includes a lifting ring 8 disposed within a support shell 2. At least two first guide posts 9 penetrate the lifting ring 8. The top ends of the first guide posts 9 are fixedly connected to the inner wall of the support shell 2. A threaded sleeve 7 is fixedly mounted on a fixing plate 12. A movable post 11 is disposed above the fixing plate 12. An elastic support member for elastically supporting the movable post 11 is mounted on the fixing plate 12. Several stop blocks 10 are fixedly connected to the bottom of the lifting ring 8, and the number of stop blocks 10 is the same as the number of movable posts 11. The bottom end of each stop block 10 has an inclined surface that cooperates with the movable post 11. An adjustment member for adjusting the height of the lifting ring 8 is mounted on the support shell 2. The support includes a prism 13 fixedly mounted on the top of the fixed plate 12. A movable block 14 is slidably sleeved on the outside of the prism 13. The movable column 11 and the movable block 14 are fixedly connected. A stop plate 15 is fixedly connected to the top of the prism 13. A first spring 16 is sleeved on the outside of the prism 13, and the two ends of the first spring 16 abut against the movable block 14 and the fixed plate 12, respectively. The adjusting component includes adjusting plates 17 fixedly mounted on both sides of the lifting ring 8. Two rectangular holes 18 are symmetrically opened on the inner walls of both sides of the support shell 2. The adjusting plates 17 pass through the rectangular holes 18. A second lead screw 19 located outside the support shell 2 passes through the adjusting plates 17. Both ends of the second lead screw 19 are fixedly connected to the support shell 2 via the first support part 20. Two threaded rings 21 are sleeved on the outside of the second lead screw 19. The two adjacent threaded rings 21 are located above and below the adjusting plate 17, respectively. The adjusting plate 17 is equipped with an anti-loosening unit that cooperates with the threaded rings 21. The anti-loosening unit includes a movable plate 23 located on the side of the adjusting plate 17 away from the lifting ring 8. Two second guide posts 25 pass through the movable plate 23. The end of the second guide post 25 away from the adjusting plate 17 is fixedly connected to a first fixed plate 26. A second spring 27 is sleeved on the outside of the second guide post 25. The two ends of the second spring 27 are respectively connected to the movable plate 23 and the first fixed plate 26. The fixed plate 26 abuts against each other, and the threaded ring 21 is provided with several limiting grooves 22. The top and bottom of the movable plate 23 are fixedly connected to limiting blocks 24, and the limiting blocks 24 are located in the corresponding limiting grooves 22. The driving mechanism includes a first gear 28 fixedly sleeved on the outside of the first lead screw 6. A support sleeve 29 is fixedly connected to the top inner wall of the support shell 2. A gear ring 30 is rotatably sleeved on the outside of the support sleeve 29, and the first gear 28 and the gear ring 30 mesh with each other. A motor base 31 is fixedly connected to the inner wall of the support shell 2. A motor 32 is fixedly connected to the top of the motor base 31. A second gear 33 that meshes with the gear ring 30 is fixedly connected to the output end of the motor 32. The motor 32 drives the second gear 33 to rotate, which in turn drives the gear ring 30 to rotate. The gear ring 30, through the first gear 28, drives the first lead screw 6 to rotate. At this time, the movable column 11 contacts the side of the stop block 10, and the threaded sleeve 7 and the movable column 11 cannot rotate relative to the support shell 2 and the anti-slip seat 4. The first lead screw 6 can then drive the threaded sleeve 7 and the anti-slip seat 4 to move downward relative to the support shell 2. When the anti-slip seat 4 contacts the ground and supports the entire device, the movable column 11 contacts the inclined surface of the stop block 10. As the first lead screw 6 continues to rotate, it drives the threaded sleeve 7 to rotate synchronously. The movable column 11 slides on the inclined surface of the stop block 10, and the movable column 11 and the movable block 14 move downward relative to the prism 13. The first spring 16... In a compressed state, as the threaded sleeve 7 continues to rotate, the movable column 11 slides past the bottom end of the stop block 10 via the inclined surface of the stop block 10. The first spring 16 then drives the movable block 14 and the movable column 11 to move upward relative to the threaded sleeve 7 to the initial height. The top of the movable block 14 contacts the bottom of the stop plate 15. The stop block 10 cannot prevent the threaded sleeve 7 from rotating relative to the anti-slip seat 4. When the first lead screw 6 rotates, it can drive the threaded sleeve 7 to rotate synchronously. When it is necessary to move the support shell 2 and the dialyzer body 1 to other positions, the second gear 33 is driven to rotate in the opposite direction by the motor 32. The first lead screw 6 drives the threaded sleeve 7 to rotate synchronously in the opposite direction. When the movable column 11 contacts the other side of the stop block 10, the movable column 11 will not contact the stop block 10. With the inclined surfaces in contact, the threaded sleeve 7 remains stationary relative to the anti-slip seat 4. As the first lead screw 6 continues to rotate, it drives the threaded sleeve 7 and the anti-slip seat 4 to move upward relative to the support shell 2. Eventually, the anti-slip seat 4 no longer contacts the ground, and the caster wheel 60 contacts the ground. The operator can then use the caster wheel 60 to push the support shell 2 and the dialysis machine body 1 to the next preset position. The operator drives the movable plate 23 to move away from the adjusting plate 17, the second spring 27 is compressed, and the limiting block 24 is no longer located in the corresponding limiting groove 22. The operator can then drive the two adjacent threaded rings 21 to rotate so that the two adjacent threaded rings 21 no longer clamp the adjusting plate 17, releasing the fixation of the adjusting plate 17 and the lifting ring 8. The driving adjustment plate 17, lifting ring 8, and stop block 10 are moved vertically to adjust the initial height of the inclined surface on the stop block 10. This ensures that after the threaded sleeve 7 and anti-slip seat 4 descend to the preset position relative to the support shell 2, the movable column 11 can slide across the bottom end of the stop block 10 through the inclined surface, allowing the threaded sleeve 7 to rotate relative to the anti-slip seat 4. After the height of the adjustment plate 17 is adjusted, the operator drives the two adjacent threaded rings 21 to rotate again, causing the two adjacent threaded rings 21 to clamp the adjustment plate 17, thus fixing the adjustment plate 17 and lifting ring 8 relative to the second lead screw 19. The operator then releases the movable plate 23, and the second spring 27 drives the movable plate 23 and the limiting block 24 to move, allowing the limiting block 24 to slide into the corresponding limiting groove 22.To prevent the threaded ring 21 from rotating and wobbling relative to the adjusting plate 17 and the second lead screw 19 due to non-human factors.

A third spring 42 is fitted on the outside of the support shell 2, and the two ends of the third spring 42 are fixedly connected to the bottom of the second support part 40 and the top of the second fixed plate 41, respectively. The swaying structure includes a protective shell 3 fixedly installed on the top of the support shell 2. The protective shell 3 is a cavity structure with an open bottom. A connecting plate 43 located inside the protective shell 3 is fixedly connected to the top of the rotating shaft 5. A fixed post 44 is fixedly connected to the top of the connecting plate 43. The fixed post 44 and the rotating shaft 5 are not aligned. A rectangular ring 46 is fitted on the outside of the fixed post 44. Movable seats 47 are symmetrically arranged on both sides of the rectangular ring 46. At least two first rolling balls 49 are embedded at the bottom of the movable seats 47, and the first rolling balls 49 are in contact with the top of the support shell 2. A guide plate 48 passes through the movable seat 47. 8 is fixedly connected to the inner wall of the protective shell 3. Two fourth guide posts 50 pass through the movable seat 47. One end of the fourth guide post 50 is fixedly connected to the rectangular ring 46, and the other end of the fourth guide post 50 is fixedly connected to the third fixing plate 51. A fourth spring 52 is sleeved on the outside of the fourth guide post 50, and the fourth spring 52 is located on the side of the movable seat 47 away from the rectangular ring 46. The two ends of the fourth spring 52 are fixedly connected to the movable seat 47 and the third fixing plate 51 respectively. A mounting seat 53 is provided above the movable seat 47. At least two second rolling balls 54 are embedded at the bottom end of the mounting seat 53, and the second rolling balls 54 are in contact with the top of the movable seat 47. Fixing brackets 56 are fixedly connected to both sides of the mounting seat 53, and a fifth guide post passes through the fixing bracket 56. The fifth guide column 55 and the movable seat 47 are fixedly connected. A fifth spring 57 is sleeved on the outside of the fifth guide column 55. The two ends of the fifth spring 57 are fixedly connected to the fixed frame 56 and the movable seat 47, respectively. A through hole 45 is opened on the top inner wall of the protective shell 3. The mounting seat 53 passes through the through hole 45, and the top of the mounting seat 53 is fixedly connected to the bottom of the dialyzer body 1. The protective shell 3 is equipped with a pushing component that cooperates with the mounting seat 53. The pushing component includes two push blocks 59 fixedly installed on the inner wall of the protective shell 3. Support blocks 58 are fixedly connected to the two mounting seats 53 on opposite sides. The two support blocks 58 are located between the two push blocks 59. The two push blocks 59 are respectively provided with inclined surfaces, and the inclined surfaces on the two push blocks 59 face opposite directions.The support block 58 has an inclined surface that cooperates with the push block 59; When the drive mechanism drives the first lead screw 6 to rotate, and the first lead screw 6 drives the threaded sleeve 7 and the anti-slip seat 4 to move downward relative to the support shell 2, the anti-slip seat 4 drives the support shaft 35 and the damping ring 38 to move downward synchronously. When the damping ring 38 contacts the top of the damping disk 37, as the anti-slip seat 4 continues to move downward, the support shaft 35 drives the second support part 40 to move downward relative to the third guide post 39. The third spring 42 is in a compressed state, and the third spring 42 applies downward pressure to the second fixed disk 41, the third guide post 39, and the damping ring 38 so that the damping ring 38 is in close contact with the top of the damping disk 37. When the anti-slip seat 4 contacts the ground, the anti-slip seat 4 provides pressure to the support shell 2 and the dialysis machine body 1. When supported, the caster wheel 60 no longer contacts the ground. The anti-rotation adjustment structure releases the restriction on the position of the threaded sleeve 7. When the drive mechanism drives the first lead screw 6 to rotate again, the first lead screw 6 drives the threaded sleeve 7 to rotate relative to the anti-slip seat 4. The threaded sleeve 7 drives the first gear plate 34 to rotate. The first gear plate 34 drives the support shaft 35 to rotate through the second gear plate 36. The support shaft 35 drives the damping ring 38 to rotate through the second support part 40 and the third guide post 39. The damping ring 38 drives the damping plate 37 and the rotating shaft 5 to rotate through friction. The rotating shaft 5 drives the fixed post 44 to slide within the rectangular ring 46 through the connecting plate 43. The fixed post 44 pushes the rectangular ring 46 to move back and forth left and right. The rectangular ring 46 drives the movable seat 47 to reciprocate left and right relative to the guide plate 48 and the protective shell 3 via the fourth guide post 50, the third fixed plate 51 and the fourth spring 52. The first ball 49 rolls on the top of the support shell 2. The design of the first ball 49 reduces the resistance encountered by the movable seat 47 when it reciprocates left and right. While the movable seat 47 moves left and right, it drives the fixed frame 56, the mounting seat 53 and the support block 58 to reciprocate left and right synchronously via the fifth guide post 55. When the two mounting seats 53 move to the left, the inclined surface on one of the support blocks 58 on the left side contacts the inclined surface on the corresponding push block 59. As the mounting seat 53 moves to the left, the inclined surface on one of the support blocks 58 on the left side contacts the inclined surface on the corresponding push block 59. As the support block 58 continues to move, the inclined surface on the push block 59 pushes the support block 58 and the mounting base 53 to move forward relative to the movable base 47. Similarly, when the two mounting bases 53 move to the right, the inclined surface on one of the support blocks 58 on the right side contacts the inclined surface on the corresponding push block 59. As the mounting base 53 and the support block 58 continue to move, the inclined surface on the push block 59 pushes the support block 58 and the mounting base 53 to move backward relative to the movable base 47. When the rotating shaft 5 rotates, the mounting base 53 can be made to sway back and forth and left and right. The mounting base 53 can drive the dialyzer body 1 to sway horizontally, making it easier for blood and dialysate to come into contact.

[0023] This embodiment of a medical dialysis method for kidney disease, using the medical dialysis device as described above, includes the following steps: Step 1: The staff uses the casters 60 to push the support shell 2 and the dialyzer body 1 to the preset position, and adjusts the position of the anti-rotation adjustment structure limit threaded sleeve 7 so that the threaded sleeve 7 is stationary relative to the anti-slip seat 4. Step 2: The drive mechanism drives the first lead screw 6 to rotate, and the first lead screw 6 drives the threaded sleeve 7 and the anti-slip seat 4 to move downward relative to the support shell 2. Finally, the anti-slip seat 4 contacts the ground, and the anti-slip seat 4 supports the support shell 2 and the dialysis machine body 1. Step 3: The position restriction of the threaded sleeve 7 is released by the anti-rotation adjustment structure. When the drive mechanism drives the first lead screw 6 to rotate again, the first lead screw 6 drives the threaded sleeve 7 to rotate relative to the anti-slip seat 4. The threaded sleeve 7 drives the rotating shaft 5 to rotate synchronously through the damping transmission assembly. Step 4: The rotating shaft 5 can drive the dialyzer body 1 to swing horizontally relative to the support shell 2 through the shaking structure, start the dialyzer body 1, and the dialyzer body 1 performs dialysis on the blood. The shaking of the dialyzer body 1 ensures that the blood and dialysate come into full contact.

[0024] Working principle: During operation, the operator uses the casters 60 to move the support shell 2 and the dialyzer body 1 to a preset position. The anti-rotation adjustment structure limits the position of the threaded sleeve 7, keeping it stationary relative to the anti-slip seat 4. The drive mechanism drives the first lead screw 6 to rotate, causing the threaded sleeve 7 and the anti-slip seat 4 to move downwards relative to the support shell 2. Finally, the anti-slip seat 4 contacts the ground, supporting the support shell 2 and the dialyzer body 1. The casters 60 are no longer in contact with the ground, and the anti-rotation adjustment structure releases the restriction on the position of the threaded sleeve 7. When the drive mechanism drives the first lead screw 6 to rotate again, the first… The lead screw 6 drives the threaded sleeve 7 to rotate relative to the anti-slip seat 4. The threaded sleeve 7 drives the rotating shaft 5 to rotate synchronously through the damping transmission assembly. The rotating shaft 5 can then drive the dialyzer body 1 to swing horizontally relative to the support shell 2 through the shaking structure, thus starting the dialyzer body 1. When the dialyzer body 1 performs dialysis on the blood, the dialyzer body 1 shakes, making it easier for the blood and dialysate to come into contact, indirectly increasing the contact area between the blood and dialysate, thereby increasing the dialysis efficiency. Furthermore, the anti-slip seat 4 supports the entire device, increasing the contact area between the entire device and the ground, and reducing the possibility of the support shell 2 and the dialyzer body 1 shaking relative to the ground. The motor 32 drives the second gear 33 to rotate, which in turn drives the gear ring 30 to rotate. The gear ring 30, through the first gear 28, drives the first lead screw 6 to rotate. At this time, the movable column 11 contacts the side of the stop block 10, and the threaded sleeve 7 and the movable column 11 cannot rotate relative to the support shell 2 and the anti-slip seat 4. The first lead screw 6 can then drive the threaded sleeve 7 and the anti-slip seat 4 to move downward relative to the support shell 2. When the anti-slip seat 4 contacts the ground and supports the entire device, the movable column 11 contacts the inclined surface of the stop block 10. As the first lead screw 6 continues to rotate, it drives the threaded sleeve 7 to rotate synchronously. The movable column 11 slides on the inclined surface of the stop block 10, and the movable column 11 and the movable block 14 move downward relative to the prism 13. The first spring 16... In a compressed state, as the threaded sleeve 7 continues to rotate, the movable column 11 slides past the bottom end of the stop block 10 via the inclined surface of the stop block 10. The first spring 16 then drives the movable block 14 and the movable column 11 to move upward relative to the threaded sleeve 7 to the initial height. The top of the movable block 14 contacts the bottom of the stop plate 15. The stop block 10 cannot prevent the threaded sleeve 7 from rotating relative to the anti-slip seat 4. When the first lead screw 6 rotates, it can drive the threaded sleeve 7 to rotate synchronously. When it is necessary to move the support shell 2 and the dialyzer body 1 to other positions, the second gear 33 is driven to rotate in the opposite direction by the motor 32. The first lead screw 6 drives the threaded sleeve 7 to rotate synchronously in the opposite direction. When the movable column 11 contacts the other side of the stop block 10, the movable column 11 will not contact the stop block 10. With the inclined surfaces in contact, the threaded sleeve 7 remains stationary relative to the anti-slip seat 4. As the first lead screw 6 continues to rotate, it drives the threaded sleeve 7 and the anti-slip seat 4 to move upward relative to the support shell 2. Eventually, the anti-slip seat 4 no longer contacts the ground, and the caster wheel 60 contacts the ground. The operator can then use the caster wheel 60 to push the support shell 2 and the dialysis machine body 1 to the next preset position. The operator drives the movable plate 23 to move away from the adjusting plate 17, the second spring 27 is compressed, and the limiting block 24 is no longer located in the corresponding limiting groove 22. The operator can then drive the two adjacent threaded rings 21 to rotate so that the two adjacent threaded rings 21 no longer clamp the adjusting plate 17, releasing the fixation of the adjusting plate 17 and the lifting ring 8. The driving adjustment plate 17, lifting ring 8, and stop block 10 are moved vertically to adjust the initial height of the inclined surface on the stop block 10. This ensures that after the threaded sleeve 7 and anti-slip seat 4 descend to the preset position relative to the support shell 2, the movable column 11 can slide across the bottom end of the stop block 10 through the inclined surface, allowing the threaded sleeve 7 to rotate relative to the anti-slip seat 4. After the height of the adjustment plate 17 is adjusted, the operator drives the two adjacent threaded rings 21 to rotate again, causing the two adjacent threaded rings 21 to clamp the adjustment plate 17, thus fixing the adjustment plate 17 and lifting ring 8 relative to the second lead screw 19. The operator then releases the movable plate 23, and the second spring 27 drives the movable plate 23 and the limiting block 24 to move, allowing the limiting block 24 to slide into the corresponding limiting groove 22.To prevent the threaded ring 21 from rotating and wobbling relative to the adjusting plate 17 and the second lead screw 19 due to non-human factors; When the drive mechanism drives the first lead screw 6 to rotate, and the first lead screw 6 drives the threaded sleeve 7 and the anti-slip seat 4 to move downward relative to the support shell 2, the anti-slip seat 4 drives the support shaft 35 and the damping ring 38 to move downward synchronously. When the damping ring 38 contacts the top of the damping disk 37, as the anti-slip seat 4 continues to move downward, the support shaft 35 drives the second support part 40 to move downward relative to the third guide post 39. The third spring 42 is in a compressed state, and the third spring 42 applies downward pressure to the second fixed disk 41, the third guide post 39, and the damping ring 38 so that the damping ring 38 is in close contact with the top of the damping disk 37. When the anti-slip seat 4 contacts the ground and supports the support shell 2 and the dialysis machine body 1, the universal wheel 60 is no longer in contact with the ground and is released by the anti-rotation adjustment structure. Regarding the position limitation of the threaded sleeve 7, when the drive mechanism drives the first lead screw 6 to rotate again, the first lead screw 6 drives the threaded sleeve 7 to rotate relative to the anti-slip seat 4. The threaded sleeve 7 drives the first gear disc 34 to rotate. The first gear disc 34 drives the support shaft 35 to rotate through the second gear disc 36. The support shaft 35 drives the damping ring 38 to rotate through the second support part 40 and the third guide post 39. The damping ring 38 drives the damping disc 37 and the rotating shaft 5 to rotate through friction. The design of the fourth spring 52 allows the movable seat 47 to slide and buffer relative to the fourth guide post 50. The design of the fifth spring 57 allows the mounting seat 53 and the fixing bracket 56 to slide and buffer relative to the fifth guide post 55 and the movable seat 47. When the rotating shaft 5 rotates, the rotating shaft 5 is driven by the connecting plate 43. The fixed post 44 slides within the rectangular ring 46, and the fixed post 44 pushes the rectangular ring 46 to move back and forth. The rectangular ring 46 drives the movable seat 47 to move back and forth relative to the guide plate 48 and the protective shell 3 through the fourth guide post 50, the third fixed plate 51 and the fourth spring 52. The first ball 49 rolls on the top of the support shell 2. The design of the first ball 49 reduces the resistance encountered by the movable seat 47 when it moves back and forth. While the movable seat 47 moves left and right, it drives the fixed frame 56, the mounting seat 53 and the support block 58 to move back and forth synchronously through the fifth guide post 55. When the two mounting seats 53 move to the left, the inclined surface on one of the support blocks 58 on the left side contacts the inclined surface on the corresponding push block 59. As the mounting base 53 and support block 58 continue to move, the inclined surface on the push block 59 pushes the support block 58 and mounting base 53 forward relative to the movable seat 47. Similarly, when the two mounting bases 53 move to the right, the inclined surface on one of the support blocks 58 on the right side contacts the inclined surface on the corresponding push block 59. As the mounting base 53 and support block 58 continue to move, the inclined surface on the push block 59 pushes the support block 58 and mounting base 53 backward relative to the movable seat 47. The mounting base 53 drives the second ball 54 to roll on top of the movable seat 47. The design of the second ball 54 reduces the resistance encountered by the mounting base 53 when moving horizontally. When the rotating shaft 5 rotates, the mounting base 53 can be made to sway back and forth and left and right.Mounting bracket 53 can drive the dialyzer body 1 to swing horizontally, making it easier for blood and dialysate to come into contact.
