A hemoperfusion and dialysis device comprises a hemodialysis machine, a hemoperfusion apparatus, a net bag and a support, wherein the support is fixed on the hemodialysis machine through a fixing frame, the bottom of the hemodialysis machine is provided with a plurality of universal wheels, a hemodialyzer of the hemodialysis machine is fixed on the support and connected with the hemoperfusion apparatus through a pipe, the top end of the support is provided with a plurality of extension arms, the tail end of every extension arm is of a circular arc shape with an concave surface facing upwards, the net bag comprises a net bag body and a handle, the net bag is of an inverted circular cone structure with both ends opened, the hemoperfusion apparatus is arranged inside the net bag body and is fixed on the extension arm of the support through the handle of the net bag. According to the hemoperfusion and dialysis device, the hemoperfusion apparatus and the hemodialysis machine are effectively connected together though the net bag, and the hemoperfusion apparatus is fixed by the support arranged on the hemodialysis machine, so that dangers that torsion and bending of a hemodialysis pipe are easy to occur or the hemoperfusion apparatus is easy to drop off can be avoided effectively.
