Hemodialysis tube

According to the embodiment of the invention, the hemodialysis tube comprises a dialysis tube body, the dialysis tube body is of a cylindrical structure with the two ends closed, and a first tubular electrode plate, a second tubular electrode plate and a third tubular electrode plate are arranged in the dialysis tube body; a tubular first reverse osmosis membrane is coaxially arranged between the first electrode plate and the second electrode plate, and a second reverse osmosis membrane is arranged between the second electrode plate and the third electrode plate. The two dialysate pipe cavities and the blood pipe cavity are arranged in a nested mode, so that the blood pipe cavity forms an annular pipeline, the inner side face and the outer side face of the annular pipeline can be adjacent to the dialysate pipe cavities, and compared with the mode that only the outer wall of the blood pipe cavity is adjacent to dialysate in the prior art, the structure is simple, and the structure is convenient.
