Dynamic body position auxiliary dialysis system and method

The dynamic body position auxiliary dialysis system comprises a human body dialysis hemodynamic state detection device and a dynamic body position changing device, and the human body dialysis hemodynamic state detection device detects state parameters of a human body in the dialysis process and sends the state parameters to a control device; the control device adjusts the dynamic body position changing device according to the state parameters so as to change the body position in the human body dialysis composition, the dynamic body position changing device is formed by connecting a plurality of movably connected plate bodies, and the body position state of a patient is changed through control of a motor. The dynamic body position changing device comprises four body position modes of a horizontal position, a leg lifting position, a leaning position and a sitting position for selection. A proper body position can be selected in the dialysis process according to the specific condition of a patient so as to cope
