Claims

[Claim for Utility Model Registration] A large number of hollow systems converging into a columnar appearance are housed in a cylinder with blood flow pipes protruding from both ends, and both ends are fixed with potting material. , a cap-shaped lid body having a gas or dialysate flow tube is integrally connected to both ends of the cylinder body, and a small chamber body having a volume expansion/contraction mechanism at both end sides of the cylinder body is installed in each cylinder body. A hollow fiber external perfusion type blood processing device characterized in that these chamber bodies are connected in a communicating state and are connected to an expansion/contraction drive device that operates the volume expansion/contraction mechanisms of each chamber body simultaneously and in opposite directions. Device.
