ポンプを用いてなる人工血液透析装置。[Claims for Utility Model Registration] (1) An elastic tube for blood circulation whose both sides are drawn out of the casing is disposed along the arcuate inner surface of the casing, and rotates to the center of the arcuate inner surface. A rotor section having a shaft is provided with a plurality of rollers that locally press the elastic tube against the arcuate inner surface, and the rotor section is rotated to send out the blood in the elastic tube and to remove the casing. In the variable tube withdrawal direction blood pump, the tube withdrawal direction variable blood pump changes the withdrawal direction of the elastic tube by reversing the rotational direction of the rotor portion in response to the reversal, the plurality of rollers being rotatably supported, respectively. a support arm; these support arms are swingably supported, rotate in conjunction with the rotation shaft, and have a through hole formed in the center that engages with the rotation shaft on both the front and back surfaces; The rotor portion includes a rotating body that can be inserted into and removed from the rotating shaft, and a spring body that is provided between the support arm and the rotating body and presses the plurality of rollers against the elastic tube. A blood pump with variable tube drawing direction. (2) An artificial hemodialysis device using the variable tube withdrawal direction blood pump according to claim (1).
