[0025] During use: Through the settings of the protective box 1, the partition 2 and the casters 51 with brakes, the movement of this product is facilitated. At the same time, during the movement, the protective box 1 and the box door 41 can protect the dialyzer 3, the blood pump 30, the dialysate pump 32, the dialysate bottle 28 and the liquid receiving bottle 29. And through the settings of the first mounting member 4, the first mounting seat 31, the second mounting seat 33 and the second mounting member 16, it can also prevent the dialyzer 3, the blood pump 30, the dialysate pump 32, the dialysate bottle 28 and the liquid receiving bottle 29 from shaking during the movement. During dialysis, arterial blood flows into the inner cavity capillary circulation of the dialyzer 3 under the traction of the blood pump 2, and then is input into the human vein through the sixth connecting tube. The dialysate in the dialysate bottle 28 enters the outer cavity dialysate chamber circulation of the dialyzer 3 under the traction of the dialysate pump 32, and then the dialysate flows into the liquid receiving bottle 29 through the fifth connecting tube to perform dialysis on the patient. Through the setting of the storage box 42, the storage of the sphygmomanometer is facilitated. And through the settings of the second driving member 43 and the sealing plate 50, it is also convenient to take out the sphygmomanometer. By starting the second motor 45 of the second driving member 43, the second motor 45 can drive the second external threaded rod 46 to rotate. The second external threaded rod 46 can drive the second screwed sleeve 47, the movable plate 48, the sliding column 49 and the sealing plate 50 to move upward, and then the sphygmomanometer in the storage box 42 can be taken out. By using the sphygmomanometer to monitor the patient's blood pressure, and then according to the data of the sphygmomanometer to predict the change of the patient's blood pressure, the opening degrees of the first solenoid valve and the second solenoid valve are adjusted, so as to control the blood dialysis speed to balance the blood pressure. When it is necessary to replace the dialysate bottle 28 and the liquid receiving bottle 29, first start the first motor 37 of the first driving member 34. The first motor 37 can drive the first external threaded rod 38 to rotate. The first external threaded rod 38 can drive the first screwed sleeves 39, the sliding plate 40 and the box door 41 on both sides to move away from each other. Then rotate the second screw rod 22 of the second mounting member 16, and the second ball will move away from the second end block 25. Then rotate the second connecting ring 20, which can drive the second external threaded tube 19 to rotate, and can drive the second docking rod 27, the second clamping ring 24 and the second sliding rod 26 to move away from the dialysate bottle 28 and the liquid receiving bottle 29. Then it is very convenient to replace the dialysate bottle 28 and the liquid receiving bottle 29. Using the same method as above, it is also very convenient to replace the dialyzer 3 that needs to be replaced.

[0026] The above description is only the preferred embodiment of the present invention and the description of the technical principles and other solutions used. At the same time, the scope of the invention involved in the present invention is not limited to the technical solutions formed by the specific combination of the above technical features.
