[0023] Sponge blocks 16 are fixed on both sides of the two concave plates 13. By using sponge blocks 11 and 16 together, the patient's arms can be clamped more vertically at the two concave plates 13 to ensure the stable progress of hemodialysis. The two first rotating plates 6 are connected by a rotating shaft. The two sets of first rotating plates 6 and the rotating shaft can be used to rotate and adjust the two sets of first rotating plates 6.

The top of the dialysis assistive device body 1 is rotatably connected to the rotating shaft seat 53. The two displacement racks 54 and the interior of the rotating shaft seat 53 are both rotatably installed with a second rotating plate 55. One side of the two displacement racks 54 is fixedly provided with an anti-slip pad 56. The anti-slip pad 56 can increase the friction between the two displacement racks 54 and the hospital bed, so as to stably fix the dialysis assistive device. A servo motor is fixedly connected to the upper side of the dialysis assistive device body 1, and the output shaft of the servo motor is fastened to the rotating shaft seat 53.

[0030] Two second slide bars 60 are fixedly installed inside the dialysis assist device body 1. The outer surfaces of the two second slide bars 60 are slidably connected to two slide seats 61. The lower sides of the two slide seats 61 are fixedly connected to two symmetrically distributed clamping seats 63. The clamping seats 63 are clamped and placed on the bed guardrail. One side of the four clamping seats 63 is clamped with a positioning plate 64. One side of the positioning plate 64 passes through the clamping seat 63 and extends to the other side of the clamping seat 63. Both ends of the two slide seats 61 are threadedly connected with bolts 62 for fixing the slide seats 61.

[0031] One side of the dialysis assisting device body 1 is fixedly connected to two symmetrically distributed L-shaped blocks 65, and four rubber recesses 66 are fixedly connected inside the two L-shaped blocks 65. A dialysis tube 67 is clamped inside the rubber recess 66, and one side of the rubber recess 66 is rotatably connected to an array-distributed swivel seat 68. One side of the swivel seat 68 is slidably connected to two pressure rods 69 for fixing the dialysis tube 67. One side of the pressure rod 69 passes through the swivel seat 68 and extends to the other side of the swivel seat 68. One side of the two pressure rods 69 is fixedly connected to the connecting plate 30, and a fourth spring 70 is fixedly connected between the two pressure rods 69 and the swivel seat 68.

[0032] When the present invention is in use, the position of the guide seat 19 is moved on the guide plate 17, and then the slide 20 will also move on the guide seat 19. At this time, the lifting frame 2 can be driven to move horizontally or vertically, and then the first electric push rod 22 drives the lifting frame 2 to adjust the height, so that the lifting frame 2 is adjusted to a position suitable for the patient's arm. Then, the patient is allowed to lie on the bed, and the patient's arm is allowed to pass between the mounting block 5 and the bottom plate 7. At this time, the patient's arm can squeeze the rotating plate 2 15 installed with the first spring 9 to rotate downward, so that the elastic rotating plate 1 8 and the rotating plate 2 15 can support the patient's arm. Then, the two placing concave plates 13 installed with the second spring 12 can be used to allow the two sponge blocks 11 to elastically fit the patient's upper arm and forearm. As the rotating plate 1 8 rotates downward, the two extension plates 27 can be used to adjust the two rotating blocks 23 installed with the third spring 25. The two rotating blocks 23 are squeezed to rotate downward, driving the sponge blocks 26 at the two arc plates 24 to further clamp and position the patient's upper arm, so as to form a double arm clamping mechanism, improve the clamping effect of the patient's arm, and ensure that the hemodialysis work is carried out stably and reliably. Then the slide plate 4 can move on the two round rods 3, and the mounting block 5 that can be adjusted by rotation can be used to allow the patient to slightly adjust the position of the arm. When the patient grasps one end of the rotating plate 2 15 with his palm, the arm at the bottom plate 7 can be freely raised or lowered by using the two sets of rotating adjustable first rotating plates 6 and the two elastic retractable concave plates 10. Such a dialysis auxiliary device does not require the assistance of medical staff for adjustment. The patient can adjust the movement trajectory of the arm independently, which is easy to operate, saves time and effort, improves the use efficiency of the dialysis auxiliary device, and makes the dialysis work safer and more comfortable. By placing the display screen 37 for displaying dialysis data separately into the rubber strip 36 of the fixing frame 35, the rubber strip 36 is allowed to fit and position the display screen 37, and then the two limiting plates 38 are moved so that the two limiting plates 38 can be positioned above the display screen 37, and then the second electric push rod 43 is extended to automatically drive the movable block 1 40 and the movable block 2 42 to rotate and adjust, so that the movable plate 34 can rotate downward and the display screen 37 can also rotate downward to adjust the viewing angle of the display screen 37, so that it is convenient for the patient on the bed to view the dialysis status, such as various dialysis indicators, The progress, etc., improve the convenience of the dialysis auxiliary device. Then, the third electric push rod 51 drives the rack 48 to move in the guide horizontal plate 47, so that the rack 48 can drive the gear rotating rod 31 to rotate and adjust, which is used to adjust the position of the display screen 37 on the top block 32. At this time, the two rollers 46 on the vertical plate 45 can move in the slide groove 44 of the semi-arc seat 28 to limit the rotation position of the display screen 37, so that the display screen 37 can be convenient for medical staff and patients to watch, thereby enhancing the patient's understanding of the dialysis process and improving the practicality of the dialysis auxiliary device. By moving the two slides 61 on the two second slide bars 60, the four clamping seats 63 on the two slides 61 can be clamped and positioned on the guardrails of the bed, and then the four bolts 62 are screwed in sequence to lock the two slides 61, and then the positioning plates 64 on the four clamping seats 63 are pushed respectively, so that the positioning plates 64 can fix the clamping seats 63 to ensure that the entire dialysis auxiliary device can be safely placed on the bed. Then, the output shaft of the servo motor drives the rotating shaft seat 53 to rotate and drives the two second rotating plates 55 to rotate synchronously, so that the two displacement frames 54 can be pulled to move toward each other on the two first slide bars 52, so that the device with anti-dialysis function installed can be safely placed on the bed. The two displacement frames 54 of the sliding pad 56 can be fitted and clamped to the two ends of the patient to further firmly position the dialysis auxiliary device so that the dialysis auxiliary device can assist in the dialysis treatment. At the same time, the dialysis tube 67 is clamped into the two rubber recesses 66, and the two rubber recesses 66 are used to limit and fix the position of the dialysis tube 67. Then, the rotating seat 68 is rotated, so that the two pressure rods 69 equipped with the fourth spring 70 can further elastically position the dialysis tube 67, so that the dialysis tube 67 used for hemodialysis is not easy to bend and entangle, thereby ensuring the smooth progress of hemodialysis and improving the versatility of the dialysis auxiliary device when used.
