[0002] The dialysis machine is a medical device that can be used to treat the patient's blood extracorporeally when the patient's renal function is limited. The blood is drawn out of the body using a dialysis tube, passed through the permeable membrane of the hemodialysis machine, and after the metabolic waste and impurities in the blood are removed, the purified blood is transported back into the body to achieve blood exchange for the patient.

[0003] When using current dialysis machines, staff often find that: current dialysis machines usually use dialysis tubes to draw blood out of the body, pass through the permeable membrane of the hemodialysis machine to remove metabolic waste and impurities in the blood, and then transport the purified blood back into the body to achieve blood exchange for the patient. However, during the blood exchange process, due to the long dialysis tube path, after dialysis is completed, the temperature of the blood will drop, and the blood is prone to coagulation outside the body. If the coagulated blood is directly flowed into the patient's body, it is easy to cause damage to the patient. Summary of the invention

[0041] Reference Figure 3 and Figure 4A heating structure 8 is provided on the dialysis machine body 2, and the heating structure 8 is mainly composed of a fixed block 81. The fixed block 81 is provided on the dialysis machine body 2, and a rotating block 82 is rotatably connected to the fixed block 81. A heating groove 83 is provided on the fixed block 81 and the rotating block 82, and a heating rod 84 is fixedly connected in the heating groove 83. A temperature sensor 810 is fixedly connected to the fixed block 81. The heating rod 84 is started to heat the water in the heating tank 83, and the water temperature is monitored by the temperature sensor 810. When the water temperature rises to the set temperature, the heating is stopped, and when the water temperature drops to the set temperature, the heating is started again. The staff moves the dialyzer body 2 to the designated position, brakes the universal wheel 3 to fix the dialyzer body 2, installs the blood outlet blood 12 on the second peristaltic pump 6, installs the dialysis tube 15 on the first peristaltic pump 5, and connects one end of the blood outlet blood 12 and the dialysis tube 15 to the patient respectively, connects one end of the waste liquid tube 14 to the waste liquid bag, and hangs the waste liquid bag on the hook 11, and connects one end of the dialysis tube 15 to the dialysate tank, and operates through the display screen 4. The first peristaltic pump 5 and the second peristaltic pump 6 are started. The second peristaltic pump 6 transmits the blood in the patient's body through the outflow blood vessel 12 to the dialyzer 7. After being filtered by the dialyzer membrane in the dialyzer 7, the dialysate enters the dialyzer 7 through the dialysis tube 15 and exchanges substances with the blood. The first peristaltic pump 5 is started. The first peristaltic pump 5 transmits the dialyzed blood back to the patient's body through the return blood vessel 13. The rotating block 82 is turned to open, and the return blood vessel 13 is clamped between the fixed block 81 and the rotating block 82. The blood passes through the return blood vessel 13 and between the fixed block 81 and the rotating block 82. It will be heated by hot water and then flow back into the body. This avoids the situation that the temperature of the blood will decrease after the dialysis is completed due to the long path of the dialysis tube 15, and the blood is prone to coagulation in vitro. If the coagulated blood is directly flowed into the patient's body, it is easy to cause damage to the patient. A heat preservation plate 85 is fixedly connected in the heating tank 83, two heat preservation cottons 87 are fixedly connected to the fixed block 81 and the rotating block 82, and a heat conduction plate 86 is fixedly connected to the fixed block 81 and the rotating block 82. The heat preservation plate 85 can improve the heat preservation effect of water in the heating tank 83. The material of the heat preservation plate 85 can be selected on the market according to specific requirements, the heat preservation cotton 87 can further improve the heat preservation effect, and the heat conduction plate 86 can improve the heat conduction effect. A round button 88 is fixedly connected to the fixed block 81 and the rotating block 82, and a clamping block 89 is rotatably connected to one of the round buttons 88. The clamping block 89 is rotated so that the clamping block 89 is clamped on the round button 88 on the fixed block 81, so that the connection between the fixed block 81 and the rotating block 82 is more stable. A fixed plate 811 is fixedly connected to the dialysis machine body 2, and a sliding plate 812 is slidably connected to the fixed plate 811. The sliding plate 812 is fixedly connected to the fixed block 81. The sliding plate 812 can be slid to drive the fixed block 81 to move, thereby adjusting the distance between the fixed block 81 and the patient. A sliding groove 813 is provided on the fixed plate 811, and a sliding rod 814 is slidably connected in the sliding groove 813. The sliding rod 814 is fixedly connected to the sliding plate 812.The staff can adjust the sliding plate 812 by sliding the slide rod 814 to make the operation more convenient. A rectangular plate 815 is fixedly connected to the slide rod 814, and a round rod 816 is slidably inserted on the rectangular plate 815. A plurality of round grooves 817 are opened on the fixed plate 811. After the position of the sliding plate 812 is adjusted, the round rod 816 can be slid to make it fit into the corresponding round groove 817 to limit the sliding plate 812. A spring 818 is sleeved on the round rod 816, one end of the spring 818 is fixedly connected to the round rod 816, and the other end of the spring 818 is fixedly connected to the rectangular plate 815. When the round rod 816 is inserted into the round groove 817, the spring 818 is in a stretched state, so the rebound elastic force of the spring 818 acts on the round rod 816, making the limit more stable.

[0042] Reference Figures 5 to 7 A mounting structure 9 is provided on the dialysis machine body 2. The mounting structure 9 mainly consists of an adjusting groove 91. An adjusting block 92 is slidably connected in the adjusting groove 91. A mounting plate 93 is fixedly connected to the adjusting block 92. A sliding groove 94 is provided on the mounting plate 93. Two sliding blocks 95 are slidably connected in the sliding groove 94. A clamping block 96 is fixedly connected to the sliding block 95. A rubber pad 99 is fixedly connected to the clamping block 96. The dialyzer 7 is placed between the two clamping blocks 96, and then the two sliding blocks 95 are slid closer to each other so that the two clamping blocks 96 clamp the dialyzer 7, which is convenient for installing the dialyzer 7. The rubber pad 99 can increase the friction to improve the stability of the installation. A bidirectional screw 97 is rotatably connected in the sliding groove 94, and the two sections of threads on the bidirectional screw 97 are in opposite directions. The bidirectional screw 97 is threadedly connected to the two sliding blocks 95, and one end of the bidirectional screw 97 is fixedly connected to a first crank 98. When the staff turns the first crank 98, the bidirectional screw 97 can be driven to rotate, thereby driving the two sliding blocks 95 to slide synchronously in opposite directions, making the clamping operation more convenient and the clamping more stable. A threaded rod 910 is rotatably connected in the adjustment groove 91, and the threaded rod 910 is threadedly connected to the adjustment block 92. One end of the threaded rod 910 is fixedly connected to a second crank 911. When the staff turns the second crank 911, the threaded rod 910 can be driven to rotate, thereby driving the adjustment block 92 to slide, thereby adjusting the position of the dialyzer 7 to prevent the return blood vessel 13 from being too loose or too tight.

[0043] Working principle: the staff moves the dialysis machine body 2 to the designated position, brakes the universal wheel 3 to fix the dialysis machine body 2, installs the blood outlet tube 12 on the second peristaltic pump 6, installs the dialysis tube 15 on the first peristaltic pump 5, and connects one end of the blood outlet tube 12 and the dialysis tube 15 to the patient respectively, connects one end of the waste liquid tube 14 to the waste liquid bag, and hangs the waste liquid bag on the hook 11, connects one end of the dialysis tube 15 to the dialysate tank, turns and opens the rotating block 82, clamps the blood return tube 13 between the fixed block 81 and the rotating block 82, starts the heating rod 84 to heat the water in the heating tank 83, monitors the water temperature through the temperature sensor 810, stops heating when the water temperature rises to the set temperature, and starts heating when the water temperature drops to the set temperature. The first peristaltic pump 5 and the second peristaltic pump 6 are operated through the display screen 4. The second peristaltic pump 6 transmits the blood in the patient's body to the dialyzer 7 through the outflow blood vessel 12. After being filtered by the dialyzer membrane in the dialyzer 7, the dialysate enters the dialyzer 7 through the dialysis tube 15 and exchanges substances with the blood. The first peristaltic pump 5 is started. The first peristaltic pump 5 transmits the dialyzed blood back to the patient's body through the return blood vessel 13. The blood passes through the return blood vessel 13 between the fixed block 81 and the rotating block 82 and is heated by hot water, and then flows back to the body, thereby avoiding the long path of the dialysis tube 15. After the dialysis is completed, the temperature of the blood will decrease, and the blood is prone to coagulation in vitro. If the coagulated blood is directly flowed into the patient's body, it is easy to cause damage to the patient. The insulation board 85 can improve the insulation effect of the water in the heating tank 83. The material of the insulation board 85 can be selected on the market according to specific requirements. The insulation cotton 87 can further improve the insulation effect, and the heat conduction board 86 can improve the heat conduction effect. The card block 89 is rotated so that the card block 89 is stuck on the round button 88 on the fixed block 81, so that the connection between the fixed block 81 and the rotating block 82 is more stable. The sliding plate 812 can be slid to drive the fixed block 81 to move, thereby adjusting the distance between the fixed block 81 and the patient. The staff can adjust the sliding plate 812 by sliding the slide bar 814, so that the operation is more convenient. After the position of the sliding plate 812 is adjusted, the round rod 816 can be slid to make it stuck in the corresponding round groove 817 to limit the sliding plate 812. When the round rod 816 is stuck in the round groove 817, the spring 818 is in a stretched state, so the rebound elastic force of the spring 818 acts on the round rod 816, making the limit more stable.Place the dialyzer 7 between the two clamping blocks 96, and then slide the two sliding blocks 95 toward each other so that the two clamping blocks 96 clamp the dialyzer 7, which is convenient for installation of the dialyzer 7. The rubber pad 99 can increase the friction to improve the stability of the installation. The staff turns the first crank 98 to drive the bidirectional screw 97 to rotate, thereby driving the two sliding blocks 95 to slide synchronously in opposite directions, making the clamping operation more convenient and the clamping more stable. The staff turns the second crank 911 to drive the threaded rod 910 to rotate, and then drives the adjustment block 92 to slide, thereby adjusting the position of the dialyzer 7 to prevent the return blood vessel 13 from being too loose or too tight.

[0044] The present solution also involves a dynamic adjustment algorithm for the dialysis process, which is used for a dynamic adjustment device for the dialysis process, including a control algorithm. The control algorithm is a control method based on proportional-integral-differential, and defines a proportional parameter as Kp, an integral parameter as Ki, a differential parameter as Kd, and a critical temperature difference as Te. It is defined that when the absolute value of E is greater than Te, it is greater, and when the absolute value of E is less than or equal to Te, it is smaller. Under different E and EC states, the steps of adaptive heating control are as follows:

[0045] S1: When E is relatively large, take Ki=0, substitute E into Kp according to the proportional algorithm, and substitute into Kd according to the differential algorithm, so that Kp is positively correlated with E, and Kd is negatively correlated with E. At this time, if E is a positive value, the PWM signal duty cycle is positively correlated with E, and increases with the increase of E. The output power of the heating device is positively correlated with the PWM signal duty cycle, and increases with the increase of the duty cycle. The heating rate is positively correlated with the output power of the heating device, and increases with the increase of the output power of the heating device; if E is a negative value, the PWM signal duty cycle decreases as the absolute value of E increases, and the output power of the heating device decreases;

[0046] S2: When E is small, substitute E into Kp according to the proportional algorithm, and substitute it into Ki according to the integral algorithm, so that Kp is positively correlated with E, and Ki is positively correlated with E. Substitute EC into Kd according to the differential algorithm, so that EC and Kd are negatively correlated.

[0047] The temperature of the dialysate can be dynamically adjusted using the algorithm described above.
